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，稻草（茎和叶）在收获后留在田间，并且很少有主要用途被确定，因此每年有超过3亿吨的稻草被作为废物焚烧。到目前为止，试图以盈利的方式收集和利用这一巨大的资源作为清洁能源的尝试几乎都失败了。在这份概念说明中，一个由领先专家组成的联盟概述了他们的大胆计划，即成为这一新兴领域的领导者，为全球2亿小规模稻农提供清洁、负担得起、可靠的能源。创新：这里概述的新方法系统地设计，以克服在3年，英国资助的“稻草能源项目”中确定的四个关键障碍，现在已经结束（2016年9月）。这些障碍是：秸秆收集的物流;稻草燃料的特性;缺乏成熟的商业模式和政策支持。克服这些问题的相应创新包括：简化的村庄规模供应链，最大限度地降低收集成本和储存成本;适合发展中国家的低成本“干式”厌氧消化技术;在公共资金的支持下，包装在创新的商业模式中以降低风险。
