Straw Innovations offers the Straw Traktor® retrofit kit that enables standard combine harvesters to collect rice straw from flooded paddies, convert it into biochar, and broadcast it while rotavating the field in a single pass. The on‑site biochar acts as a durable soil amendment that improves yields and qualifies for carbon‑credit markets, while the integrated process cuts equipment costs and fuel consumption for rice growers.

Problem
Rice cultivation generates an equivalent amount of straw to the rice harvested, but the straw is difficult to extract from flooded paddies. Consequently, most straw is burned or left to decompose, releasing large quantities of methane and contributing to roughly 1 Gt CO₂e emissions annually—more than the global aviation sector.
Solution
Straw Innovations equips standard combine harvesters with the Straw Traktor® retrofit, a three‑in‑one system that harvests rice straw in waterlogged fields, broadcasts biochar onto the soil, and rotavates the land in a single pass. The collected straw is processed into biochar, a stable carbon product that serves as a high‑performance soil amendment, enhancing fertility and crop yields while sequestering carbon for centuries. By integrating straw removal, biochar application, and land preparation, the technology reduces the need for separate equipment, cuts fuel consumption, and lowers capital expenditures for farmers. The resulting biochar can also be sold or used to generate renewable energy, creating additional income streams and supporting carbon‑credit opportunities.
Target Audience
Primary customers are rice growers and agribusiness operators in Asia who manage flooded paddies, as well as rice millers and large‑scale agricultural cooperatives seeking to reduce emissions, improve soil health, and increase farm profitability.
