Agriculture Biomass Infrastructure at Industrial Scale

Despite millions of smallholder farmers in Southeast Asia bearing the cost of a climate crisis they did not create, the billions of capital beginning to flow in response were reaching almost none of them. We built Arukah to change that, and carbon removal credits were the instrument.

During COVID-19, an estimated 100 million people across Asia fell below $2 per day. The majority were smallholder farmers, families working plots of land typically smaller than two hectares.

Joanna Yeo, Arukah's founder, had spent a decade at Morgan Stanley and Figure Technologies building financial infrastructure that allowed institutional capital to enter markets it previously could not access with confidence. She turned that same expertise toward a different question: how do you connect climate capital to the farmer absorbing its consequences?

The answer was agricultural waste. 

Beyond 117 million tonnes of rice residue annually, vast quantities of broad agricultural byproducts are produced in Southeast Asia. A large share is burned openly: an estimated 60 to 70 million tonnes of rice straw alone is set alight each year, releasing CO₂ and fine particulate matter that contributes to respiratory disease, reduced visibility, and soil degradation in the  surrounding communities where farmers and their families  reside and work. Yet that same material, converted through pyrolysis, becomes one of the most durable forms of carbon storage and a soil amendment that measurably improves agricultural yields

The missing piece to utilize this agricultural waste to the benefit of the farmer at scale was the physical and financial infrastructure in between. Arukah built that infrastructure. 

What You Are Buying

Arukah issues biochar carbon removal certificates (CDRs) under Puro and Isometric. Each credit is permanent, independently verified, and traceable from feedstock intake to registry issuance. Our flagship facility in Takeo Province, Cambodia, Southeast Asia's largest biochar operation, processes 60 tonnes of feedstock per day. New facilities in Thailand and the Philippines are in active development, each targeting 10,000 CDRs annually. 

Every tonne carries a real-time provenance record through CarbonCast, our proprietary dMRV system, and on first issuance in Cambodia in March 2026, it delivered 0% post-audit deductions. The farmer income model is not peripheral to credit quality. It is the mechanism that stabilises it. Consistent payment produces consistent feedstock.

That is why the 50% revenue commitment exists, and it is a material reason the credits are as clean as they are.

What a Purchase Represents

For every $1 spent on CDR, $0.50 goes verifiably to farming households in the host country.

Agricultural waste that would otherwise have been openly burned is instead locked permanently into soil. Farmer income is verified individually for project participation.

49%
Independent estimates for annual income uplift per participating farmer in Cambodia.
Outcomes are tracked, verified and available for inclusion in annual sustainability reporting across CDP, GRI and TCFD frameworks.

Availability and Scale

By 2032, Arukah plans to operate 100 facilities across Cambodia, Thailand, and the Philippines, producing one million CDRs yearly. Each facility is built to the same infrastructure blueprint, runs on the same CarbonCast verification stack, and operates under the same farmer income model.

Forward offtake agreements across one to five year terms are available now. Buyers who move early secure supply and pricing from a producer with a clean audit record, before that window closes.
