Environmental impact
Agricultural waste is diverted away from open burning and converted into long-lived carbon sinks — an expected 1,500 tonnes CO₂e removed per year, with soil fertility and water retention restored across agricultural plots.

Project overview
Built from
the ground up.
Located in West Sumatra, this project works with local farmers to turn abundant crop waste into biochar. The same “Pit-to-Plot” approach: no complex reactors, just pyrolysis in the soil where the residue already sits.
Each pit becomes a small carbon factory, turning what used to be burned into long-lived storage while improving soil fertility and water retention. Together they capture up to 1,500 tonnes of CO₂ a year.
Our pioneer site doubles as a living lab where farmers, researchers and nature are all part of the experiment. Audited by CERES-CERT AG and registered under Carbon Standards International, it is a blueprint for climate action that is simple, circular and built from the ground up.
The science
Simple yet impactful.
Energy efficiency
No fossil fuels
Low-input, high-output method relying solely on controlled pyrolysis of on-site biomass.
1:5 ratio
Net CDR-to-feedstock
For every 5 tonnes of crop waste, 1 tonne of stable carbon is sequestered — low operating cost, high scalability for distributed rural systems.
Living lab
National testbed
Agronomic trials run with agronomists, universities and carbon accounting partners, contributing to Indonesia’s evidence base for biochar removal.
dMRV
Three-layer verification
On-ground sampling and lab soil testing, remote sensing for biomass and land-use tracking, and data monitoring for transparency.
Expected soil results
+15–25% increase in soil organic carbon. +20% improvement in moisture retention within one cropping cycle. Up to 50% reduced fertiliser dependency, with improved crop resilience.
Carbon capture data
Each soil pit yields biochar locking away an estimated 2–3 tonnes of CO₂e per hectare, depending on feedstock composition and burn conditions.
Impact & benefit
What the project changes
on the ground.
Scientific advancement
The site is a national testbed for biochar research and agronomic trials, run with agronomists, universities and carbon accounting partners. The data contributes to Indonesia’s emerging evidence for biochar-based removal.
Community benefits
Local jobs in waste collection, pit construction and soil application. Training for farmers, students and researchers. A new income stream and circular agriculture capacity that strengthens local livelihoods.
Scalability
Simplicity drives scale.
Local potential
Up to 30,000 tCO₂e a year
Expanded across available agricultural waste in the regency alone, this model could offset up to 30,000 tonnes CO₂e annually. Now imagine it across the whole of Indonesia’s farming regions.
Modular design
Decentralised hubs
Scalable to farms of any size, adaptable to plantation waste, garden trimmings and crop residues, and accessible with minimal training and equipment investment.
