ASHCRETE TECHNOLOGIES

ZERO ASH IN LANDFILLS INITIATIVE

Every day, millions of tons of Waste Incineration Ash are disposed of in landfills posing a great potential to contaminate ground and surface water, air, and soil, these are examples of Waste Incineration Ash currently disposed of in landfills:

Municipal Solid Waste (MSW) Incineration Ash or Waste to Energy Incineration Ash,

Hazardous Waste Incineration Ash,

Medical Waste Incineration Ash,

Industrial Waste Incineration Ash,

Water Treatment Plant Sludge Incineration Ash,

Biomass Incineration Ash, etc

At Ashcrete Technologies we have developed the unique technology in the world to treat, transform and upcycle “ASH” into a beneficial composite material that can be used instead of concrete.

The resulting composite material or “Ashcrete” is a true Ecological concrete “Ecoconcrete” or Green concrete as waste in this case “Ash” is used instead of aggregate (sand and gravel).

Our Initiative pretends to upcycle Ash that has been disposed of in landfills as well as the fresh ash that is generated daily and transform these waste streams into beneficial structures (Roads, Bridges, Barriers, Extreme Weather Condition Structures, Marine Environments, etc.).

We have tested around the world, and with the input from Governments, Professors and scientists, we were able to develop our technology, so far:

In the USA the Environmental authority is the State Department of Environmental Protection and the permit is called a Beneficial Use Determination, we have talked with several municipalities, in New York, we have already applied for Municipal Solid Waste Incineration Ash Beneficial Use Determination -Status: Pending BUD Petition No. 1395-0-00.

In Canada, the permit is issued by the Ministry of Environment, and we are already working with Metro- Vancouver and the BC Ministry of Environment.

In Singapore, the National Environmental Agency is responsible for ash beneficial uses permits, we have presented a project for Ash and other wastes characterization at Semamkau landfill

Once we have environmental permits and with the results of the municipality needs we proceed to transform the ash into beneficial structures.

This video will give you an idea of what needs to be done, this case example is the Municipal Solid Waste Incineration Ash Monofill located in Babylon, Long Island – New York, USA, which is about to reach full capacity.

How you can help! and why we need your help!

Our Research requires specialized testing as Ash must be fully characterized in order to determine the right ash treatment, all these tests are expensive, we would very respectfully like to ask for your economical support to contribute to our Research, if you wish to contribute by paying for the tests or do the tests at your lab we will send you the samples and we will be immensely grateful, additionally, if you wish to contribute with lab equipment it is also welcome, here are some of the tests that we usually require in addition to the engineering test.

BS EN12457- 1:2002, APHA 3120B or APHA 3125B, APHA 3500-Cr (B), APHA 3120B or APHA 3125B, APHA 3125B or APHA 3112B or Mercury analyzer, APHA 3120B or APHA 3125B, APHA 4110B, APHA 4110B or APHA 4500-C, APHA 4110B or APHA 4500-F, APHA 4110B, APHA 4500-NH3 (D) or (H), APHA 4500-N (C) or JIS K0102.45.5:2010, USEPA 6010C or APHA 4500-P (H) / (I) or HACH 8190, APHA 5310B, APHA 5220B or HACH 8000, USEPA 8260C, USEPA 5021A, USEPA SW-846-Test Method 1311 TCLP, USEPA 8270D or HACH 8047, USEPA 3545A, USEPA 8270C or USEPA 8270D, USEPA 3545, USEPA 8270D, USEPA 5021A or USEPA 3546, USEPA 8015C, NIOSH 9002, Column Leaching Test, XFS, others as required by the specific Ministry of Environment or State Environmental Authority.

Demonstration Project

In Canada, Metro Vancouver owns an Energy from Waste plant located in Burnaby, this facility generates 43,000 tons a year of Incineration Bottom Ash Ash and 11,000 tons a year of Incineration Fly Ash which are disposed of in landfills, ash transportation to landfills, treatment, and management exceeds 2.5 million dollars a year.

We have signed agreements with Metro Vancouver and are in the process of obtaining environmental permits from the British Columbia Ministry of Environment for a Municipal Solid Waste Incineration Combined Ash upcycling into green concretes or ecoconcretes pilot-demonstration project, the project overall pretends to stop All the Municipal Solid Waste Incineration Combined Ash (Bottom Ash and Fly Ash) from reaching the landfills, while dramatically lower current ash disposal and management costs and upcycle and transform the ash into beneficial structures to fight sea-level rise and coastal erosion in Vancouver.

Municipal Solid Waste (MSW) Incineration Bottom Ash and Combined Ash transformation.

At Ashcrete Technologies we have developed the unique technology in the world that transforms Municipal Solid Waste (MSW) Incineration Bottom Ash and Combined Ash (MSW Bottom Ash + MSW Fly Ash) into a composite material concrete-like that can be used to make Roads, Bridges, Barriers and Marine Structures turning this waste stream 100% sustainable contributing to a circular economy.

Ash transformation takes place at atomic level where ash ions get stimulated by nanocomposites allowing their absorption by the products generated during hydration reaction. The absorption can be divided into physical absorption and chemical absorption. Physical absorption is caused by van Der Waals forces between particles, while chemical absorption is the result of chemical bond formation.

Ashcrete is a true green concrete made with 100% Waste Materials (MSW Incineration Ash), the dense matrix prevents deleterious solutions from penetrating into the matrix, so the mechanisms that can cause conventional concrete to deteriorate are not present, consequently, durability properties, as measured by permeability tests, freeze-thaw tests, scaling tests, abrasion tests, resistance to ASR, and carbonation, are significantly better than those of conventional concrete.

The below table shows the migration of elements, in yellow raw ash elements, in green XRF elemental analysis of Ashcrete (Composite concrete-like material made with MSW I. Ash).

Ashcrete Strength

At 28 days Ashcrete surpasses the 30 Mpa (>4000 psi) mark.

ENVIRONMENTAL TESTS

Researching Hazardous Waste Incineration Ash Beneficial uses since 2010 and thanks to the input of different governments worldwide, Universities and Scientists, is that today the transformation of Municipal Solid Waste Incineration Ash is a reality, turning this waste stream into a beneficial structure with wide uses in infrastructure development.

Ashcrete is an impermeable, dense, and strong true green or eco-concrete, made with MSW Incineration Ash, the Ashcrete making process begins with Incineration Ash gradation to different particle sizes this process is imperative to achieve a perfect matrix particle packing.

The metals recovery from the Ashcrete process is >0.355mm.

Landfill and Monofill MSW I. Ash Transformation

Countries worldwide have used different methods for Ash storage, in some countries only Bottom Ash is stored in monofills and the Fly Ash after acid treatment is stored in other landfills, other countries treat the Fly Ash combine it with Bottom Ash and posteriorly store the combined ash in monofills, other countries due to space store in landfills MSW I. Ash along with other non-incinerable materials.

Ashcrete Technology can recycle any type of Ash Landfill or Monofill and transform the stored waste stream into beneficial structures that can be used in Land reclamation projects, Sea Barriers, Roads, Bridges, Barriers etc.
