Kepler Carbon · Permanent carbon removal

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.

01 · The source

It starts in Chinese farmland.

Every harvest leaves behind straw, stalks and husks: carbon the plants pulled from the air while they grew.

02 · The problem

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.

03 · The process

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.

04 · The material

Stable, porous carbon.

Every batch is tested in an accredited lab for carbon content and stability before a single tonne is sold.

05 · The store

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.

The result

2.5 tonnes of CO₂ removed for every tonne of biochar.

What we do

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.

01 · Credits

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.

02 · Fertilizer

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.

03 · Crops

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.

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.

05 · Restoration

Biochar soil remediation

Large areas of Chinese farmland suffer from acidification and salinization. We use biochar to restore soil structure and fertility.

WHY KEPLER · 01

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.

WHY KEPLER · 02

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.

WHY KEPLER · 03

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.

Work with us

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.
