Services/About Us

Research and Pro bono Consulting

We started our journey with a vision to improve the well-being of humanity and secure a brighter future for our children. Since 2010, we have been conducting research on the beneficial uses of hazardous waste incineration ash, CO2 capture technologies, and the storage of CO2 in ash.

Thanks to the collaboration and support of various governments, universities, and scientists worldwide, we have successfully transformed municipal solid waste incineration ash into a valuable resource for infrastructure development. It’s worth noting that all our research has been self-funded, and we have not received any financial support from any government, entity, or individual.

If you are researching any beneficial uses of ash, please do not hesitate to contact us.

Landfill and Ash Monofill MSW I. Ash Recycling

Various countries around the world have adopted different methods for storing MSW I. Ash, with some opting to store only Bottom Ash in monofills while treating and storing Fly Ash separately in landfills. Others have combined the two types of ash and stored them together in monofills (USA), while some countries store MSW I. Ash alongside other non-incinerable materials in landfills due to space constraints.

At Ashcrete Technology, we have developed a recycling process that can transform any type of Ash from landfills or monofills into useful structures that can be employed in a variety of projects, such as land reclamation, sea barriers, roads, bridges, and barriers.

Ash Landfill Characterization

Municipal solid waste (MSW) incineration is a widely used method for waste management that aims to reduce the volume of waste that is sent to landfills. However, the ash produced from the incineration process is still a significant environmental concern that requires proper disposal. MSW incineration ash monofills have been utilized as a means of disposing of the ash, but the environmental risks associated with their use necessitate proper characterization.

Characterizing an MSW incineration ash monofill is important to understand the potential environmental impacts that may arise from its operation. The characterization process involves gathering data on the physical, chemical, and biological properties of the ash monofill, which can help to identify potential hazards such as leaching of contaminants into the environment, air pollution from volatile organic compounds and heavy metals, and potential damage to soil and vegetation.

In addition to environmental risks, there are also potential health risks associated with MSW incineration ash monofills. Some of the contaminants present in the ash can be harmful to human health if they are released into the environment or if people come into direct contact with them. Therefore, characterizing an MSW incineration ash monofill is essential to ensure that the landfill is managed properly, and any risks to the environment and human health are minimized.

Municipal Solid Waste Incineration Bottom Ash Recycling

Welcome to Ashcrete Technologies, where we are committed to transforming ash into a valuable resource. We are proud to offer our innovative solution for recycling bottom ash, a byproduct of the combustion of Municipal Solid Waste or any other Waste, into a beneficial material that can be used in a variety of applications.

Our process involves recovering ferrous and non-ferrous metals greater than 0.45 mm from the bottom ash, while simultaneously encapsulating any heavy metal contaminants at the nano level. This ensures that the resulting material is safe and environmentally friendly.

One of the most exciting aspects of our process is that the ash ceases to exist, and is instead transformed into a new material that has numerous beneficial properties. This material can be used as a replacement for traditional construction materials, such as cement and concrete, and has been shown to be just as strong and durable, while also being lighter and more sustainable.

At Ashcrete Technologies, we are committed to sustainability and reducing the environmental impact of industrial processes. Our bottom ash recycling process is just one example of how we are turning waste into a valuable resource, while also contributing to a more sustainable future.

If you have any questions about our process or would like to learn more about how we can help your organization reduce its environmental impact, please don’t hesitate to contact us. We look forward to working with you!

Municipal Solid Waste Incineration Fly Ash Treatment and Recycling

Recycling Municipal Solid Waste Incineration fly ash requires treatment with acid, which upgrades it into a sand-like material suitable for mixing with other materials such as bottom ash, concrete debris, waste ceramics, waste glass, or sand. The alkalinity of the fly ash must be maintained within a specific range to prevent the solubility of lead or cadmium. During the process, soluble lead is converted into insoluble lead phosphate compounds chloropyromorphite and hydroxypyromorphite, while cadmium is converted into cadmium carbonate or cadmium hydroxypyromorphite. Both compounds become insoluble at pH levels above 8.0.
