Rice is the world's number one food crop, but its stems and leaves (straw) are a major waste product in developing countries, especially in Asia where around 300 million tonnes of it are burned each year for disposal, damaging the environment and human health. It is generally a poor quality feed for livestock and is not suitable for incorporating back into flooded rice fields, which would result in emissions of methane - a powerful greenhouse gas. Prior research has shown that it can be made into a clean-burning cooking fuel (biogas) using anaerobic digestion, but there are many technical and non-technical barriers to be overcome, such as getting the straw from the field to a hub economically and overcoming challenges in processing it into fuel. This project brings together two innovative businesses and leading academics in their field to set up a field trial in the Philippines, backed up by significant lab work and analysis in the UK. The aim is to develop a practical solution that could profitably serve remote communities of rice farmers, who are among the 3 billion people worldwide who lack clean cooking fuel but are surrounded by this vast, underused bioenergy resource.

大米是世界上排名第一的粮食作物，但其茎和叶（稻草）是发展中国家的主要废物产品，尤其是在亚洲，每年大约3亿吨它被燃烧以处置，损害环境和人类健康。通常，这是牲畜的质量较差，不适合将其掺入淹没的稻田中，这将导致甲烷的排放 - 一种强大的温室气体。先前的研究表明，它可以使用厌氧消化制成清洁燃烧的烹饪燃料（沼气），但是有许多技术和非技术障碍物要克服，例如将稻草从经济上从田野中纳入枢纽，并克服了将其加工到燃料中的挑战。该项目汇集了两家创新的业务，并在其领域领先的学者在菲律宾建立了一次实地试验，并得到了英国大量的实验室工作和分析的支持。目的是开发一种实用的解决方案，该解决方案可以盈利地为稻农的偏远社区提供盈利，他们是全球30亿人缺乏干净烹饪燃料但被这种庞大，未充分利用的生物能源资源所包围的人之一。
