Carbon you can see.
We develop, certify and deliver measurable CO₂ removal made from Chinese crop residues. Scroll to follow one tonne from orbit to the soil.
ScrollIt starts in Chinese farmland.
Every harvest leaves behind straw, stalks and husks: carbon the plants pulled from the air while they grew.
Straw that would burn, or rot.
Burned or left to decay, its carbon returns to the atmosphere within a few seasons. We collect it from partner farms instead.
Heated without oxygen.
At a partner plant in Anhui the straw does not burn. It turns into biochar, logged batch by batch with feedstock, temperature and weight.
Stable, porous carbon.
Every batch is tested in an accredited lab for carbon content and stability before a single tonne is sold.
Locked into the soil for centuries.
Spread into fields with GPS-logged placement, the carbon stays put while the soil holds more water and nutrients.
Most carbon credits are a number on a screen.
Ours is a layer in a field.

One material. Six ways it creates value.
Built around biochar, Kepler connects carbon credits, green agriculture, soil restoration and industry support into one value chain.
Credit generation and trading
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.
Carbon credits
Biochar fertilizer R&D
We blend biochar with organic fertilizer into low-carbon products that cut chemical input, build healthier soil and grow better crops.
Soil and fertilizer
Biochar-grown rice
Starting with healthy rice, we grow green crops with biochar fertilizer and build a supply chain from Chinese fields to international tables.
Crops
Balcony potting mix
Low-carbon living also happens on a city balcony. Our biochar-based mix lets households grow fresh, safe food in the smallest spaces.
Potting mix
Biochar soil remediation
Large areas of Chinese farmland suffer from acidification and salinization. We use biochar to restore soil structure and fertility.

China–Europe green hub
Through overseas investment and China–Europe green transition forums, we connect technology, capital and policy across borders.
China–Europe bridgeFrom Berlin to Hefei.
Standards, buyers and capital flow into China.
Biochar, removal and know-how reach the world.
14 tonnes. Our first international purchase, Zhejiang Baguatian on Below2.
Science and integrity first.
We only develop verifiable, clearly additional, permanent removal. Every credit is backed by a documented chain of evidence that buyers and auditors can follow from field to registry. Batches that fail the lab are excluded, and we record why.
Full-chain delivery.
From site to retirement, our teams cover project development, digital MRV and trading, and work with independent verification bodies at every issuance. Fewer hand-offs means less lost information, and one batch ID follows each tonne from plant gate to registry.
Global reach, local roots.
Our teams and projects span multiple countries. We are fluent in international registry rules and in the ESG procurement standards of multinational buyers, and at home in Chinese agriculture, working alongside governments, industrial parks and farmers.
Let's take carbon out of the air.
Buyers sourcing durable removal, plants and fertilizer companies looking for international registries, and investors backing the delivery record: there is a route for each of you.
