Built Around Waste. Designed for Impact.
The Nexchar process begins where the environmental cost is highest — and converts it into something valuable.
Agricultural Residue
India generates approximately 500 million metric tonnes of crop residue each year. A substantial portion of this — largely rice and wheat straw — is burned in open fields, releasing particulate matter, carbon monoxide, and CO₂ into the atmosphere while destroying soil nutrients.
Each tonne of crop residue burned releases approximately 3 kg of particulate matter, 60 kg of CO, and 1,460 kg of CO₂. Nexchar's process diverts this residue stream, converting it into electrode carbon and soil-amendment biochar instead.
Carbon-Negative by Process
Biochar production from crop residue is an inherently carbon-negative process. Pyrolysis locks organic carbon into a stable form — removing it from the short-cycle atmosphere and storing it in solid biochar — rather than releasing it through burning or decomposition.
Life Cycle Assessment establishes that the combined carbon capture from biochar production and on-site syngas energy recovery outweighs the greenhouse gas emissions of the manufacturing process. Microwave-assisted pyrolysis reduces embodied energy further, contributing to a meaningfully lower lifecycle carbon footprint than conventionally produced imported activated carbon.

Energy From the Process Itself
Microwave-assisted pyrolysis generates gasification byproducts — syngas and bio-oil volatiles — which are combusted on-site to supply process heat. This closed-loop energy design reduces external energy demand and moves the platform toward operational self-sufficiency at scale.
Full-Spectrum Valorisation
Electrode Carbon
Activated carbon meeting EDLC electrode specifications — the primary product, supplied to supercapacitor manufacturers.
Soil Amendment Biochar
Biochar that does not meet electrode-grade specification is directed to agricultural use — improving soil water retention, carbon content, and microbial activity.
Amorphous Silica Co-Product
Amorphous silica recovered from rice straw deashing — a value-added co-product for construction, refractory, and coating applications.
Nothing from the input stream is wasted.
Carbon Credit Pathway
Nexchar's process is engineered to generate registrable biochar carbon removal credits under leading methodologies, including Verra and Gold Standard. Carbon registration is a deliberate part of our platform design — not an afterthought.
We are building toward European Biochar Certificate (EBC) BasicMaterials class certification, anchoring European market access and full carbon credit participation.
Community Impact
Direct jobs created per facility
Rural households supported indirectly through feedstock procurement
Feedstock procurement creates a local income stream for farmers from residue that previously had little commercial value
Modular plant design allows facilities to be sited close to biomass clusters — keeping economic activity local
