Unser Beitrag zur Nachhaltigkeit

How do we contribute to sustainability?

Sustainability is the future, but how do we get there?

Sustainability is for us to be a part of the circular economy where we reduce or eliminate: our outtake of finite resources, toxic in circular streams, and our consuming effect on future generations. Our contribution is within the phosphorus and waste incineration industries. Please read more on what problems these sectors have and how we contribute to a little more sustainable world.

Ash2Salt – extended information

Process overview


The Ash2Salt process is built upon two preceding steps (as can be seen in the picture above). Fly ash is washed with water in the fist step and out goes washed ash (residual sand), and a leachate of salt and heavy metals continues to step two. In step two sulfides is used to precipitate heavy metals from the leachate and thereafter the chloride filled liquid continues to the Ash2Salt process in step three. In step three the Ash2Salt process takes place and CaCl2 (solution), NaCl, and KCl are produced with a single evaporator. In addition are extracted water from the Ash2salt process recirculated to the first step.

In a wash-plant for fly ash without the Ash2Salt process, following limitations exist:

  • The wash-plant must have permission to discharge large amounts of chloride effluents
  • The chlorine content of the ash can vary depending on what the incineration plants burn resulting in different amounts of chloride effluent must be discharged.
  • A need for fresh water

The main advantages of having the third Ash2Salt process step are:

  • Enables washing of fly ash without a discharge of chlorides
  • Can handle variations of chlorine content from the ash
  • Creates a source of income by production of pure commercial salts and ammonia
  • No need for fresh water since the Ash2Salt washes fly ash with land fill leachate and process water.

LCA of our Ash2Salt process


A life cycle assessment (LCA) has been performed to compare Easymining's new Ash2Salt process with some of today’s fly ash treatment processes available for Swedish and European fly ash.

It can be concluded from table 1 that the Ash2Salt process substantially reduces the impact of CO2-emissions on today's fly ash handling. It should be noted that the CO2 reduction of the Ash2Salt process heavy depends on the (reasonable) assumption that the salts recycled from fly ash replaces conventionally produced salts.

The LCA was carried out as a master thesis Kristin Johansson at Uppsala University and the Swedish University of Agricultural Sciences. The thesis can be found here (only in Swedish).

CleanMAP – extended information

Process overview


Current methods of phosphorus production require high phosphoric acid concentrations to produce phosphate salts. These high concentrations are achieved by energy-intensive evaporation processes, and metal impurities such as cadmium are difficult to remove from the phosphoric acid.

The CleanMAP technology enables cost effective production of pure and well-defined mono-ammonium phosphate (MAP) or di-ammonium phosphate (DAP) of technical grade with a cadmium content < 1 mg Cd/kg P (< 0.5 mg Cd/kg P2O5). CleanMAP can be parallel-integrated into an existing production line (Figure 1), replace an existing production line (Figure 2), or be used in new plants.

Figure 1. CleanMAP technology parallel-integrated to an existing production line

Figure 2. CleanMAP technology replacing existing parts in a plant

The technology is based on selective extraction coupled with chemical precipitation. The technology is less dependent on the concentration of the phosphoric acid feed solution, and the main advantage is a reduction of energy demand since there is no requirement for phosphoric acid concentration by water evaporation.

State-of-the-art concentrating of phosphoric acid by water evaporation


To produce merchant-grade phosphoric acid, high acid concentrations are required and in a state-of-the-art system, this is done by evaporating water. Phosphoric acid is normally concentrated in three stages, as shown in Figure 3. The acid from the filter (28% P2O5) is concentrated to 40% P2O5 in a single stage vacuum evaporator. The acid is then clarified to remove precipitated solids and the clarified acid is further concentrated to 54% P2O5 in two stages. The inter-stage concentration is about 48% P2O5. The 54% P2O5 acid is then used for commercial ammonium phosphate production. Concentration of  phosphoric acid through evaporation is a very energy-intensive process.

Figure 3. Concentrating phosphoric acid using evaporation

Energy savings


The amount of steam required for concentrating phosphoric acid usually varies between 2.3 and 5 tons of steam per ton of phosphorus depending on production conditions. If the phosphoric acid is purified by solvent extraction the energy demand is about 7 tons of steam per ton of phosphorus. Figure 4 shows the energy cost of water evaporation to concentrate phosphoric acid.

Energy savings of approx 5 ton steam or 5 MW/ton phosphorus (2.2 ton steam per ton P2O5) can be achieved if evaporative concentration is avoided.

Figure 4. Energy consumption for phosphoric acid concentration

Capital savings


The CleanMAP technology renders entire plant sections to be unnecessary such as:

• Evaporators
• Steam distribution systems
• Condensation systems
• Cooling water systems
• Acid storage facilities
• De-sulfatationsystems
• De-fluorination systems

Capital costs for the new technology are lower than excluded plant sections.

Maintenance savings


Reduced maintenance costs are mainly due to the removed need for sludge and scale removal from evaporation systems.

Output from the CleanMAP process


Mono-ammonium phosphate, MAP (technical grade)

  • Application, fertilizer on agricultural field or in horticulture, feed ingredient
  • Quality, Technical grade 26,5% P (61% P2O5 and 12% N)
  • Cadmium content < 1mg Cd/Kg P (Cd < 0,5 mg / Kg P2O5)
  • Efficiency in application, very high, the product is fully water soluble and plant available
  • Corresponds to CAS-nr: 7722-76-1

Ammonium phosphates is produced in two quality levels, fertilizer grade and technical grade. Fertilizer grade is the large volume phosphorus commodity and contains 21-22% P (48% P2O5), but is not fully water soluble and also contains impurities from the production process (gypsum etc). Fertilizer grade also contains metals in relation to the content in the raw material and can only be distributed to the crop in solid form. The CleanMAP process always produce technical grade MAP (highest quality), which is fully water soluble and can be used for fertilization in solid or liquid form.

Summary of how the CleanMAP technology distinguish itself from state-of-the-art


State-of-the-art

  1. All water is removed by evaporation
  2. Limited to concentrated P streams
  3. Phosphate salts are concentrated
  4. Impurities remain in products

CleanMAP

  1. Phosphate is separated from water requiring steam through ion sorption 
  2. Enables processing of dilute P steams (no steam)
  3. Phosphate salts are precipitated
  4. Easy separation of impurities becoming resources

Ash2Phos – extended information

Process Overview


The Ash2Phos process can be divided into two concepts (as can be seen in the picture above) depending on the size of the plant and its location: the City concept and the Industrial concept.

City concept

The city concept is an option for smaller ash volumes and stops at the intermediate products, which will have to be upgraded to final products at a different industrial site. To lower operation costs, waste acid (low-quality hydrochloric acid, HCl) from the gas cleaning of a waste incineration plant can be used to dissolve the ash in the Ash2Phos process. Since the City concept handles lower amounts of ash, locally produced waste acid is often enough to match the City concept's acid demand. In addition to a lower operational cost for the Ash2Phos process, the incineration plant will also lower it's operational costs since it no longer has to neutralize and treat the waste acid.

Industrial concept

The Industrial concept includes the steps necessary to produce commercially valuable products, which are already traded on the market.

The Ash2Phos process consists of 3 steps: a first acidic step, a second alkaline step where intermediate products are produced, and finally a conversion step where the intermediates are processed into final products.

The main inputs of the process are

  • Ash from incinerated sewage sludge
  • Acid (hydrochloric acid, HCl)
  • Lime

The outputs of the process are

  • Phosphorus, preferably as ammonium phosphate (fertilizer, requires addition of ammonia to the process) or calcium phosphate (feed additive). It is also possible to produce phosphoric acid or super phosphate fertilizers.
  • Iron as iron chloride or iron sulfate
  • Aluminum as aluminum sulfate
  • Residual sand (undissolved ash consisting mainly of silicates)
  • Heavy metal precipitate (for safe disposal)
The process itself

The process consists of several successive chemical reactions undertaken at room temperature (though one process step may benefit from a temperature of 40 degrees C). There is no need for pressurized vessels or for exceptional materials to be used for the equipment. The mass balance of the process is favorable, since all input chemicals become part of the products.

Possible Phosphorus Products


Monoammonium phosphate, MAP

  • Uses: Fertilizer in agriculture or horticulture. Animal feed ingredient.
  • Quality: Technical grade, 26,5% P (61% P2O5) and 12% N
  • Cadmium content: < 1 mg Cd/kg P (< 0.5 mg Cd/kg P2O5)
  • Efficiency in application: Very high, the product is fully water soluble and plant available
  • Corresponds to CAS number: 7722-76-1

Ammonium phosphates are commercially produced in two quality levels: fertilizer grade and technical grade. Fertilizer grade is the large volume phosphorus commodity and contains 21-22% P (48% P2O5). Fertilizer grade products are not fully water soluble and can only be distributed to the crop in solid form. It also contains impurities from the production process, such as gypsum, and metals originating from the minerals used as raw material. The Ash2Phos process always produces the highest quality of ammonium phosphate, i.e. technical grade, which is fully water soluble and can be used for fertilization in solid or liquid form.

Dicalcium phosphate, DCP

  • Uses: Fertilizer in agriculture or horticulture. Animal feed ingredient.
  • Quality: Equal to currently available products with a phosphorus content of 18% P (41% P2O5)
  • Cadmium content: < 1 mg Cd/kg P (< 0.5 mg Cd/kg P2O5)
  • Efficiency in application: Equal to currently available products
  • Corresponds to CAS number: 7783-28-0

Phosphoric acid

It is also possible to produce phosphoric acid with the same low cadmium content of < 1 mg Cd/kg P (< 0.5 mg Cd/kg P2O5).

  • Corresponds to CAS number: 7664-38-2

Superphosphates

A less likely alternative is to produce single or triple super phosphate. These products are lower grade phosphorus fertilizers which were common in the past, but have been mostly replaced by ammonium phosphates.

Iron and Aluminum Products


Iron

Two different iron products can be produced in the industrial concept from the intermediate product ferric hydroxide.

Iron chloride, FeCl3

  • Application: Coagulant used for precipitation of phosphorus and organic materials in waste water treatment plants
  • Quality: The product equals the current commercial product
  • Correspond to CAS number: 7705-08-0

Iron sulfate, Fe2(SO4)3

  • Application: Coagulant used for precipitation of phosphorus and organic materials in waste water treatment plants
  • Quality: The product equals the current commercial product
  • Correspond to CAS number: 7782-36-0
Aluminum

Aluminum sulfate, Al2(SO4)3

  • Application: Coagulant for precipitation of phosphorus and organic materials in waste water treatment plants
  • Quality: The product equals the current commercial product
  • Correspond to CAS number: 10043-01-3

Residual Sand & Heavy Metal Precipitate


Residual sand

The remaining ash residue after dissolution

  • The washed sand consists mainly of silicates
  • The sand has several possible applications such as cement or filler in concrete
Heavy metal precipitate

The heavy metals are separated as a sulfide precipitate for disposal. Metal sulfides are chemically stable and sulfide precipitation is a state-of-the-art technology which is widely in within industrial water treatment.

Summary of the Ash2Phos Process


A chemical process with the following characteristics

  • Phosphorus from sludge ash is recovered as high value products (ammonium or calcium phosphates)
  • High phosphorus recovery rate (> 90%)
  • Clean phosphorus products with a very low cadmium content of < 1 mg Cd/kg P (< 0.5 mg Cd/kg P2O5)
  • Recovery of iron & aluminum as precipitation chemicals
  • Separation of heavy metals as chemically stable sulfides for safe disposal
  • Favorable mass balance
  • Low energy consumption since the process operates at ambient temperature and atmospheric pressure
  • Can use sludge ashes with lower phosphorus content than ash from mono-incineration
  • Can use waste acid from incineration plants

Fly ash

Air pollution control residue (APCR) from waste incineration

What is fly ash?


Fly- and bottom ashes are produced when waste is incinerated. The fly ash is light and has in the past exited from the chimney of the incineration plant. Modern legislation requires that the fly ash is captured before it reaches the air since it contains hazardous materials (depending on the source), such as, dioxides, heavy metals, and on average 20% chloride salts (mainly originating from plastic).

What problem comes with fly ash?


The captured fly ash from waste incineration is today difficult to land fill or use since it has high chlorine content. Fly ash from coal incineration can today be used in the cement industry, but that field of application is not possible if the ash has a high chloride content since chlorides lowers the abrasion resistance of the cement. Land filling of fly ash is today also difficult to manage since the chlorides easily leaches when it rains on land fill piles of fly ash.

How is fly ash managed today?


Sweden is every year producing approx. 300 000 ton of fly ash from waste incineration. The main part is considered a hazardous waste and needs to be stabilized (to avoid leaching of chlorides and heavy metals) to pass the regulatory requirement of land filling. Approximately half of Sweden's fly ash is exported to a nature reserve at an island in Norway. The fly ash that stays in Sweden is mainly stabilized with different methods and then land filled.

Is it possible to use fly ash to something useful?


All methods that are used today to take care of fly ash have in common that they are not a sustainable long term solution for fly ash management. So, what are the main problems that prevent useful applications for fly ash? The hazardous regulations for fly ash mainly comes from the chlorides, but also to a less extent due to heavy metals. Removing these contents would declassify the ash and at the same time open up possibilities for useful applications.

Is it possible to remove the chlorides?


Yes, it is possible. There are washing plants for fly ash available to the market, but today these washing plants comes with three big challenges:

  • The salt that is being washed out from the fly ash contains different types of chlorides (commercially useless) and therefore needs to be released to a recipient (preferably a water area that can handle large amounts of salt)
  • The washing plant needs to separate leaching heavy metals and nitrogen (which originates from ammonia addition during the flue gas treatment process)
  • Large investment

EasyMining's solution for a sustainable management of fly ash?


EasyMining’s Ash2Salt process has the ability to separate chlorides and heavy metals from fly ash. The main advantage is that the Ash2Salt process can produce three types of commercial salts from the chlorides in the fly ash:

  • Potassium chloride (KCl)- used as fertilizers or fertilizer raw material
  • Calcium chloride (CaCl2)- used for de-icing and road surfacing
  • Sodium chloride (NaCl)- used for road salt and input to chlor alkali industry

The main benefits are that:

  • The plant doesn’t need to be built near a water recipient.
  • Create a source of revenue from selling commercial salts.
  • Remove on average 20% of the fly ash mass.
  • Make the residual fly ash less hazardous and thereby available for applications.

Phosphorus

 

A necessary element for life

What is phosphorus and why is it important to care about?


Phosphorus (P) is an element and essential for all life on earth since all living cells contain phosphorus. Phosphorus is necessary for the growth of new cells, which leads to phosphorus biggest application today, mineral fertilizers for the agriculture and as feed supplements for animals. The world's food production would be halved without the addition of phosphate fertilizers. With a growing population demanding an increased food production, the phosphorus supply is and will be even more important in the future since phosphorus as an element can’t be replaced.

Where does the phosphorus come from?


Phosphorus is a highly reactive element and is therefore never found as a free element in the nature. Most of earth’s phosphorus are therefore contained as minerals in the earth's crust and rocks with high accumulation of phosphorus minerals, called phosphate rocks. The phosphate rock is mined and used to produce fertilizers for farming, feed stock, and other applications that needs phosphorus. The world's phosphate rock resources are not equally distributed, and the largest deposits are in Morocco (West Sahara), China, and Algeria.

Can we run out of phosphorus?


Phosphorus can’t be destroyed, but we can redistribute and thereby dilute the existence of concentrated phosphorus deposits, i.e. phosphate mines. Phosphorus is in that sense both a fossil resource and an unlimited resource. Peak Phosphorus refers to a point in time when humanity reaches a maximum production level of phosphate rock as a commercially viable raw material (if no changes in phosphorus management are done). After that point, mining phosphate rock will not be economically feasible and food production will therefore decline.

Can we avoid Peak Phosphorus?


A key difference between Peak Oil and Peak Phosphorus is that oil can be replaced with other forms of energy or materials when it gets to scarce while there isn’t substitute for phosphorus. A different approach must therefore be used to avoid Peak Phosphorus; effective management through recirculation of mined phosphorus and efficiency in production and use to extend its life cycle.

How can phosphorus be recirculated?


The phosphorus is accumulated in plants and animals when it's used as fertilizers and feed supplements by the agricultural industry. Humans eats the food and send most of the phosphorus to waste water treatment plants (WWTP). Most of the phosphorus is through the water cleaning processes accumulated in the sewage sludge. Avoiding to remove phosphorus from the waste water before sending it to the recipient causes massive over-fertilization of its surrounding environment. The Peak Phosphorus scenario can therefore be avoided or substantially delayed by extracting phosphorus from the sludge and recirculating it to the agricultural industry. For example, Sweden is using approx. 10 000 tons' phosphorus in agricultural fertilizing, while Sweden’s sewage sludge together with feed industry wastes (mainly slaughterhouse wastes) contains approx. 8 000 tons of phosphorus.

Are we recirculating any phosphorus from sewage sludge today?


Yes. Sweden and EU are respectively recirculating 25% and 48% of the phosphorus from the sewage sludge production through distributing it on agricultural land. Unfortunately, it doesn't come with no risks, since untreated sewage sludge contains heavy metals, pathogens, and medical residues. Heavy metals, such as, cadmium are absorbed by plants and constitutes a serious health risk to humans by increasing the risk of developing bone, kidney, and heart diseases. Pathogens and medical residues effect on agriculture have in recent years being studied extensively and gained higher importance since it is suggested that medical residues possibly can increase antibiotic resistance and pathogens can reach out to drinking water areas.

Why are we spreading sewage sludge on farmland if it can be harmful to humans and the environment?


Distributing sewage sludge on farmland is today considered as ”good enough” since it is seen as the easiest way to recirculate phosphorus and increase our sustainability. Sweden have a rigorous control system for WWTP, but new content limit legislation that require WWTPs to invest in upstream cleanness and other purification investments are causing them to look for other alternatives for disposal of their sewage sludge .

How can we increase the recirculation of phosphorus to the agricultural industry?


There are some competing technologies for recirculating phosphorus to the agricultural industry in addition to distributing sewage sludge to the farmland. There are two main ways of extracting phosphorus from sewage sludge. The first way is to extract phosphorus directly from the sludge. The other way is to first heat or incinerate the sludge and thereafter extract the phosphorus from the residue (such as ash). Both ways have their advantages and disadvantages.   

Direct extraction from sewage sludge

  • Advantages: Few process steps and relatively small capital investments. Mature technology and a simple infrastructure.
  • Disadvantages: The sludge are expensive to transport and manage since since the sludge contain large amounts of water. Technologies that extract phosphorus from the sludge have low extraction ratios of phosphorus and therefore also have high operative costs P/ton.

Extraction from ash of incinerated sewage sludge

  • Advantages: Incineration decreases the weight of the sewage sludge with 90% consequently making the transport considerably cheaper. In addition to concentrating the phosphorus, incineration kills all pathogens and evaporates all medical residues. The higher concentration of phosphorus (P/ton) makes the operative cost of extracting phosphorus lower.
  • Disadvantages: The incineration itself is expensive and requires relatively high capital costs. The technology of extracting phosphorus from ash is less mature and the infrastructure is more complex.

What do EasyMining think about the future of phosphorus recirculation?


The most important thing for a sustainable phosphorus management is that phosphorus is recirculated to the agricultural production and stays in the recirculating cycle. We believe that the future of sustainable phosphorus management requires phosphorus products that:

  • The agricultural industry accepts and are as good or better than today’s products
  • Are pure and safe to use
  • Have high plant availability
  • Can be used for precision fertilization
  • Mainly are based on recirculated phosphorus

How is EasyMining working to reach a sustainable phosphorus management?


EasyMining’s process for recirculating phosphorus from sewage sludge ash is called Ash2Phos and is a wet chemical process that uses ash from incinerated sewage sludge. The main advantage of Ash2Phos is that the process can produce pure commercial phosphorus products called mono-ammonium phosphate (MAP) or di-calcium phosphate (DCP) and at the same time separate heavy metals, such as, cadmium from the sludge.

Agriculture

Agriculture

Pure fertilizers enables safe and sustainable agriculture


We believe it's important that fertilizers used for agriculture are safe to use when it comes to contents of heavy metals, pathogens and medical residue. Phosphate rock (raw material for phosphorus fertilizers) can contain impurities, such as, high levels of cadmium and uranium. Impurities are today not separated during the production process and end up in the phosphorus fertilizer products. A heavy metal, such as, cadmium that accompanies phosphorus fertilizers from for example phosphate-mines in Morocco (world's largest deposits of phosphate rock) have proven to be toxic for human health and is one of six substances banned by the European Union's Restriction on Hazardous Substances (RoHS) directive. Recent data from epidemiological studies suggest that intake of cadmium through diet are associated with a higher risk of developing endometrial, breast and prostate cancer as well as to osteoporosis in humans.

Our starting points when we created the Ash2Phos process was that our fertilizer products need to be:

  1. A product that agriculture want and use today
  2. Pure and safe to use
  3. Delivering high plant availability
  4. Able to be used for precision fertilizing

We have made a comparison between the Ash2Phos product and the products from competing technologies below.


Comparison of Ash2Phos and competing technologies

Fertilizer industry

Fertilizer industry

Are you planning to or already producing MAP and want to lower your energy costs? EasyMining has the perfect solution for you!


High energy consumption can be a hassle when producing water soluble MAP (mono-ammonium phosphate). The central part of the CleanMAP technology is to extract phosphorus from P streams in the form of pure, solid and water-soluble phosphate salts (MAP, DAP) in a cost-effective way. We promote three main benefits of the Clean MAP process:

Reduced capital costs
The CleanMAP technology renders entire plant sections to be unnecessary such as evaporators, steam distribution systems, condensation systems, effluent gas treatment systems, cooling water systems, and acid storage facilities. Capital costs for the new technology are lower than excluded plant sections.

Reduced operational and maintenance costs
Reduced operational costs are mainly due to exclusion of the need for steam for acid concentration, and no need for complex effluent gas treatment. Reduced maintenance cost is mainly achieved due to the absence of sludge and scale removal from evaporation systems.

Quality difference – technical grade vs. fertilizer grade
The CleanMAP technology enables direct production of MAP or DAP of technical grade. Separation of pollutants such as cadmium, uranium and fluorine is achieved. The products are well defined and completely water-soluble. Phosphorus concentration is about 20 percent higher than in ammonium phosphates of fertilizer grade.


 

Incineration

Incineration of sewage sludge


Incineration of sewage sludge is an effective way of reducing the residual mass from waste water treatment plants (WWTP) with around 90%. One problem is what to do with the ash from the incineration? EasyMining provides the perfect solution!

The Ash2Phos process requires ash that comes from incinerated sewage sludge. We estimate that a phosphorus content in the ash of at least 4 % is needed for the Ash2Phos process to be economically viable. The consequence and benefit is that the sewage sludge doesn’t necessarily need to be mono-incinerated (around 9% phosphorus content), but also can to some extent be co-incinerated with materials that produce low amount of ashes.

Fly ash from incinerated waste


Fly ash is formed during air pollution control in waste incineration plants. The fly ash normally contains heavy metals and on average 20% chloride salts and is therefore characterized as hazardous waste. There are different ways of how the fly ash can be managed and land filled. Some ways are worse than others when it comes to sustainability.

Through a unique patented method called Ash2Salt can EasyMining extract commercial salts from waste incineration fly ash. In the Ash2Salt process the fly ash is washed and from the wash water commercial grade potassium chloride, sodium chloride and calcium chloride as well as an aqueous ammonia solution are extracted. By taking away the chlorides, the amount of waste is reduced by on average 20% and the commercial salts can be returned to society so that the extraction of virgin resources can be reduced. The washed fly ash (residual sand 80%) are now considered a non-hazardous waste and can be used in, for example, the cement/concrete industry.


The Ash2Salt technology creates a sustainable and circular flow of resources

Sewage treatment

Sewage treatment


A challenge for a waste water treatment plant (WWTP) is to effectively separate phosphorus from the outgoing water, but also how to recycle the phosphorus that ends up in the sewage sludge. There are some developing and developed solutions out there today, but many of them offers only a small recycling potential for the phosphorus in the waste water/sewage sludge. In addition, the recovered phosphorus products are often not compatible with the requirements and needs of the farmers, i.e. not well known fertilizer products. The consequence is that it’s hard if not impossible to get a monetary value from the phosphorus in the sewage sludge.

EasyMining has a process called Ash2Phos that can extract phosphorus from ash of incinerated sewage sludge. The main advantage of the Ash2Phos process is that it produces well known products that today are commercially traded and accepted in agriculture. In addition, the process extracts more than 90% of the phosphorus from the sewage sludge ash and at the same time produce iron chloride and aluminium sulfate (precipitation chemicals). The catch is that the Ash2Phos process doesn't directly use sludge but needs ash of incinerated sewage sludge for its process.The positive side is that almost all phosphorus in the sludge is recovered and that there is no need for new investment in the WWTP.

Ash2Salt

Background


Incineration is a common method for municipal solid waste treatment since it reduces the amount of waste, enables destruction of pathogens and organic contaminants, as well as possible recovery of energy in form of heat and/or electricity. Figure 1 visualize how fly ash is produced through incineration.

Even though incineration substantially reduces the waste's volume and mass, bottom- and fly ash are produced in large quantities. The fly ash is captured in the incineration plant's air pollution control and is often considered to be a hazardous waste when being disposed in a land fill. This is due to a high content of water-soluble chlorides and heavy metals in the fly ash. Because of its hazardous properties, it is expensive and problematic to manage.

Fly ash from Sweden is today mainly stored in special constructed land fills or on a discharged lime stone mine in Norway. The land fill and storing alternatives are not sustainable in a long-term perspective, but are temporary accepted because there is a lack of attractive alternatives.

Figure 1. How fly ash is produced

 

The problem


The high chloride content of the ash makes it impossible (with current legislation) to land fill it without proper pre-management that avoids leaching of chlorides and stabilizes heavy metals. This pre-management is expensive and today only a few players can handle the fly ash. About 50% of Sweden's produced fly ash is exported to Norway.

The solution


EasyMining’s patented Ash2Salt process is unique and can extract commercial salts from high chlorine containing fly ashes. After washing, the ash residue can be land filled without an exemption for high chloride contents. The Ash2Salt process can extract commercial grade:

  • Potassium chloride (KCl)
  • Sodium chloride (NaCl)
  • Calcium chloride (CaCl2)
  • Aqueous ammonia solution or ammonium sulfate

Economic benefits


  • Substantially reduces the hazardousness of fly ash
  • Lowers the fly ash's mass by (on average) 20%.
  • Creates an income source from commercial valuable salts and ammonia.

Technological benefits


  • A new energy effective and patented process for separating salts
  • In addition to the three salts types, the process also produce an ammonia product that can be used in incineration plants for flue gas treatment
  • Separates heavy metals from the fly ash
  • Can handle different levels of salts in the fly ash

Environmental benefits


  • Decontaminates and reduces waste
  • Converts a linear waste flow into a circular resource flow
  • Reduces the need for virgin raw materials
  • Recovers potassium, a valuable non-renewable plant nutrient

A new Ash2Salt plant is planned in Högbytorp in Sweden


EasyMining's parent company, Ragn-Sells have come far in the planning of a full scale Ash2Salt plant at their site in Högbytorp, Sweden.

CleanMAP

Background


From phosphate mines, phosphate rock is produced and shipped to fertilizer industries. The fertilizer industry is traditionally using large amounts of energy when producing highly concentrated phosphoric acid from the phosphate rock. The phosphoric acid is thereafter used as a raw material for different types of phosphate fertilizers.

Problem


A substantial part of the fertilizer industry's operational cost (energy) comes from the need concentrating for phosphoric acid through water evaporation. The processes also often lack the ability to remove heavy metals, such as, cadmium from the end product. 

Solution


The CleanMAP Technology enables cost effective production of pure and well defined mono ammonium-phosphate (MAP) or di-ammonium phosphate (DAP), of technical grade(i.e.fully water soluble). The cadmium content in the ammonium phosphate product is below 1 mg Cd/Kg P. The CleanMAP technology can be integrated parallel in existing production line, replacing existing production line or in new plants.

Economic benefits


  • Reduced operational costs are mainly due to exclusion of the need for steam for acid concentration, and no need for complex effluent gas treatment
  • Reduced maintenance costs are mainly due to no need for sludge and scale removal from evaporation systems
  • Energy savings of ca 5 ton steam/ton phosphorus (ca 2.2 ton steam per ton P2O5) is achieved compared to state-of-the-art production of fertilizer grade ammonium phosphate production

Technological benefits


  • Enables direct production of MAP or DAP of technical grade
  • Phosphorus concentration in MAP of technical grade is about 20 percent higher than in ammonium phosphates of fertilizer grade.
  • More energy-efficient than state-of-the-art
  • Separation of pollutants, such as, cadmium, uranium and fluorine is achieved

Environmental benefits


  • Low contamination of final products - The cadmium content in the ammonium phosphate is below 1 mg Cd/Kg P (<0.5 mg Cd /kg P2O5)
  • Less energy demanding than state-of-art

Ash2Phos

Background


Phosphate rock is the primary raw material source for phosphate production, but unfortunately is mineable phosphate rock a limited non-renewable resource. Large amounts of phosphorus end up in manures and in urban waste, mainly in sewage sludge and slaughterhouse waste. Today are EU countries re-circulating phosphorus by distributing 48% of the sludge back to farmland, as can be seen in figure 1. The positive aspect is that phosphorus is re-circulated, but it's not problem free. Sewage sludge can still contain viruses, heavy metals, and other substances that could be harmful to human health. Today 27% of the phosphorus is being transported to land fills or "other", which are routes that rarely recover any phosphorus. 25% of the sludge is incinerated and the ash is mainly transported to land fills. The Ash2Phos process can in a near future transform the sludge ash to a raw material for phosphorus extraction and thereby be a part of a circular solution for phosphorus management.

Figure 1. EU countries are good at capturing phosphorus from the sludge but not effective at recirculating it...

Problem


Ash from mono-incinerated sewage sludge has a high concentration of phosphorus (7-10%), iron, and aluminium (5-10%), but also contains unwanted heavy metals such as cadmium. The high content of metal creates an obstacle for possible applications for the phosphate rich ash.

Solution


In the Ash2Phos process, sludge ash is treated in a wet chemical process for the recovery of phosphorus, aluminium, and iron as clean commercial products, and at the same time are the unwanted heavy metals separated for disposal.

The Ash2Phos process comes in two designs, the MAP or DCP.  The commercial products from the MAP process are:

  • Mono-ammonium phosphate (MAP)
  • Calcium chloride
  • Iron Chloride
  • Aluminium Sulphate

The commercial products from the DCP process are:

  • Di-calcium phosphate (DCP)
  • Iron Chloride
  • Aluminium Sulphate

Economical benefits


  • Low energy consumption - 30 kton ash plant requires energy equivalent to approx 80 households
  • Favorable mass balance - Operative income/cost ratio estimation 1,55
  • Relatively low capital cost investment 

Technological benefits


  • Produce valuable high-grade commercial products independent of ash quality: MAP/DCP and Iron chloride & Aluminium sulfate.
  • Removes cadmium and heavy metals from the phosphorus (< 1 mg Cd/Kg P, < 0.5 mg Cd / Kg P2O5))
  • More than 90% recovery rate of phosphorus from the ash
  • Can use waste acid from incineration plants
  • Low labor intensity

Environmental benefits


  • Recovery of clean phosphorus products
  • Production of precipitation chemicals that can be recycled to waste water treatment plants
  • Detoxify the waste
  • Reduce the need for virgin rock phosphate
  • Reduce the amount of waste for disposal
  • Create a circular flow of resources

A new factory is planned based on the patented Ash2phos technology

Ny teknik för återvinning av fosfor

Den ”cirkulära ekonomin” bygger på att vi återanvänder, lagar och fixar till, alltså att det som du betraktas som ”skräp” egentligen är en tillgång som kan användas igen. Motsatsen är den ”linjära ekonomin” som bygger på uttag av råvara, tillverkning och användning av produkter, vilka kasseras och hamnar på soptippen. Den senare modellen fungerar så länge som vi förutsätter att jordens resurser är oändliga, tillgängliga och billiga
