We use all

Cutting-edge waste conversion through gasification

In the process of gasification, various byproducts are produced, including hydrogen, carbon dioxide (CO2), and slag.
By leveraging the applications of hydrogen, CO2, and slag, we can contribute to sustainability goals, reduce environmental impacts, and create value from waste materials.
These applications demonstrate the versatility and potential of hydrogen, carbon dioxide, and slag in various sectors, from energy and industry to construction and manufacturing, contributing to sustainability and resource efficiency goals.

Unmatched Feedstock Flexibility

Revolutionizing Recyclingy

“Unmatched feedstock” typically refers to materials or resources that are currently underutilized or not effectively matched with appropriate uses within a particular industry or context. In the context of a circular economy, unmatched feedstock could refer to materials that are being wasted or discarded instead of being repurposed or recycled.

Addressing unmatched feedstock is a key aspect of transitioning to a circular economy. By identifying and effectively utilizing these underutilized resources, businesses and industries can reduce waste, minimize environmental impact, and create economic value from materials that would otherwise be discarded. This often requires innovative technologies, processes, and business models to unlock the potential value of these materials and integrate them into the circular economy loop.

BIOTECHWORKS-H2 gasification can process waste with minimal pre-treatment of feedstock

BIOTECHWORKS-H2 gasification can handle wastes with 50% moisture content, though optimum results are
obtained at moisture contents below 20%

Gasification Process Functions

How Does Gasification Work

Our gasification is a fixed bed gasification system that breaks down waste at the molecular level. After the waste is shredded, it is fed into the top of the gasifier vessel through an airlock. Purified oxygen and steam are injected at supersonic speeds into the base of the gasifier using patented lances. The resulting thermochemical reaction occurs at temperatures close to 2,200°C (4,000°F). As the waste descends through the gasifier by gravity through four reaction zones: drying, devolatilization, gasification, and melting. These processes produce high-quality syngas, liquid metal, and inert stone.

01

Polisher zone

Condensable tars in the raw syngas exiting the top of the bed are fully converted to additional syngas using controlled reactions with oxygen and stream at 2,000°F(1,100℃).
The tar-free syngas then exits the top of the gasifier ready for downstream processing.

Oxygen and steam are injected into the bottom of the gasifier producing hot syngas that rises and exchanges heat with the bed of waste material.
This supports additional gasification reactions, devolatilization, and drying.

02

Drying and devolatilization zone

Waste enters the side of gasifier and is dried by rising hot syngas. The waste then descends into the devolatilization zone where a mix of light gases, hydrocarbons, and condensable tars are released at 1,300°F(704℃).

Solids that escape with the gas are cleaned out of the syngas and recycled back into the gasifier during gas cleaning.

03

Gasification zone

Gasification occurs in the lower section of the vessel where the remaining carbon-containing materials in the waste react with the steam and oxygen.

The exothermic gasification reaction raises the temperature of the lower zone from about 2,500°F(1,371℃) to 4,000°F(2,204℃) allowing for the through conversation of remaining carbon into syngas; the large amount of energy produced at this stage allows the system to be self-sustaining.

04

Melting zone

At 4,000°F(2,204℃), inorganic compounds and metals melt and collect at the bottom in a molten state. This is removed as non-leaching inert stone and recovered metals.

The ultra temperatures of the gasification allow the system to completely convert mixed waste without producing toxic by-products.
