Science and integrity first.
We only develop verifiable, clearly additional, permanent removal, backed by a documented chain of evidence from field to registry.

Every plantbreathes incarbon.
Kepler Carbon develops, certifies and delivers measurable CO₂ removal made from Chinese crop residues, and keeps that carbon in the soil for centuries.

01
Straw
Every year, Chinese farms leave behind vast amounts of rice and wheat straw.
Burned or left to rot, its carbon returns to the air.
We collect it from partner farms in Anhui, and turn it into something that stays.
02
Char
At a partner pyrolysis plant the straw is heated in the absence of oxygen. Instead of burning, it turns into biochar, a stable carbon skeleton that keeps much of the carbon the plant absorbed.
A
Heat without oxygen
Pyrolysis, O₂-free, with plant energy metered.
B
Measured, batch by batch
Each batch gets an ID and is sampled in an accredited lab. Its carbon content and stability ratios decide how many tonnes of removal it can claim, before anyone sells anything.

Soil
Dig down 20 cm. That black line is the product.
Most carbon credits are a number on a screen. Ours is a layer in a field you can photograph, sample and measure again in ten years. Spread with GPS-logged placement, the biochar holds water and nutrients for the farmer while its carbon stays out of the atmosphere for centuries.
0 cm
Crops and roots
Water and nutrients stay where roots can reach them, so yields hold steadier through difficult seasons.
0–10 cm
Topsoil moisture
Biochar pores store water and release it slowly, helping crops ride out dry spells.
10–20 cm
The biochar layer
The carbon store itself. Measured batch by batch, verified by independent bodies and issued by a registry.
20–30 cm
Nutrients and microbes
A vast charged surface holds nutrients and gives useful bacteria and fungi a home.

Proof
A tonne in the soil becomes a credit only when someone independent has checked it.
We develop biochar removal projects and issue and trade credits on Carbonfuture, Isometric and Puro.earth, so every tonne removed in Chinese fields becomes an asset recognised worldwide.
