Rice Straw Biogas Hub
A collaborative climate mitigation project based in the Philippines, funded by Innovate-UK.

Work Packages 1 and 2

Establishing climate-friendly practices in rice production and farm operations through innovative technologies

Straw Innovations Ltd leads the Rice Straw Bioenergy Hub and is transforming rice straw into renewable energy for farmers in the Philippines.

To optimize the removal of rice straw from paddy fields, Straw Innovations has adopted a variety of advanced harvesters. This approach could potentially lower the costs of harvesting and collecting rice straw, addressing one of the major challenges in rice straw management. Traditionally, the slash-and-burn method has been a common practice, or rice straw is simply left to decay in the field. Both practices contribute significantly to greenhouse gas emissions, making the need for more sustainable alternatives even more urgent.

Meanwhile, the team is also working on testing out renewable energy technologies that could power rice drying. Thus far, the team already explored gasification, and anaerobic digestion (biogas production), and in 2025, they plan to execute the pyrolysis method.

Conducted several sets of anaerobic digestion treatment, exploring various ratio and proportion that will highlight rice straws potential for biogas production.

By the end of 2025, it is expected that all operations from efficient straw collection, through transportation and processing at the hub, to productive bioenergy use for drying and milling rice, will be completed. The system holds potential for cutting rice emissions by more than 50%, whilst creating added value and jobs for local rice farming communities.
