Unlike rice husks (that cover the grain), rice straw (stems and leaves) is left in the field after harvest and few major uses have been identified, so more than 300 million tonnes of it are simply burned each year as waste. To date, attempts to profitably collect and use this vast resource for clean energy have almost all failed. In this concept note, a consortium of leading experts outline their bold plan to be leaders in this emerging field and provide a route to clean, affordable, reliable energy for the world's 200 million small-scale rice farmers.Innovation: The novel approaches outlined here are designed systematically to overcome the four key barriers identified in the 3 year, UK-funded 'Rice Straw Energy project', which is now ending (September 2016). The barriers are: logistics of straw collection; rice straw fuel characteristics; lack of proven business models and policy support. The respective innovations to overcome them are: a simplified, village-scale supply chain that minimises collection costs and storage; a low-cost 'dry' anaerobic digestion technology appropriate for developing countries; packaged in an innovative business model with support from public funding to reduce the risks.

与稻壳（覆盖谷物）不同，收获后的稻草（茎和叶）被留在田间，很少有主要用途，因此每年仅将其中超过3亿吨被烧成废物。迄今为止，试图盈利地收集和使用这种庞大的资源来清洁能源，几乎都失败了。在此概念上，由领先专家组成的一个联盟概述了他们在这个新兴领域成为领导者的大胆计划，并为世界上2亿个小型水稻农民提供清洁，负担得起，可靠的能量的途径。Innovation：Inning概述的小说方法是系统地设计的，以克服三年的四个关键障碍，在英国Fund Fund fund fund'rice Project'，现在是2016年的最终范围。障碍是：收集稻草的物流；稻草燃料特征；缺乏可靠的业务模型和政策支持。克服它们的各自的创新是：简化的，乡村规模的供应链，可最大程度地减少收集成本和存储；适合发展中国家的低成本“干”厌氧消化技术；在公共资金的支持下，以创新的商业模式打包，以降低风险。
