Agricultural waste in sub-Saharan Africa has significant untapped potential for biogas production. Biogas technologies are being applied to the conversion of some of these wastes into clean renewable energy, but to date this has relied largely on first generation 'wet' anaerobic digestion (AD) systems with high capital and operational costs and high parasitic energy loads.In this project, a consortium of leading experts outline to introduce innovative and efficient sequencing batch 'dry' AD system enabled by robust ancillary monitoring systems that will optimise the AD process. This will be supported in county with increased analytical capacity building that will support this project and the wider AD sector, addressing one of the key failure points for AD systems - lack of technical support.This will provide a route to clean affordable energy in rural sub-Saharan Africa by utilising high dry matter and high cellulose wastes.This novel approach is systematically designed to overcome the key barriers to adoption and sustainability of energy from waste fed AD systems; capital cost, complexity, operational cost and local capacity. The AD system will be designed as a flat pack system to be built in Kenya using local components for final installation. In the commercial phase this enables rapid roll out of the technology whilst the project developers ensure quality of build and IP.The business model looks to provide value to wastes through heat and power generation, selling these services to the agro processing sector, that are coming under increasing legislation in terms of waste control whilst having intermittent power supply. Excess biogas will be dried and compressed and used in local communities for cooking, lighting and cooling. Digestate will be processed to a compost and reused back in agriculture.The respective innovations will help to overcome the energy trilemma whilst providing commercial ecosystems services to business and communities.

撒哈拉以南非洲的农业废物在沼气生产方面具有巨大的未开发潜力。沼气技术正被应用于将其中一些废物转化为清洁的可再生能源，但迄今为止，这在很大程度上依赖于第一代“湿”厌氧消化（AD）系统，该系统具有高资本和运营成本以及高寄生能量负荷。领先的专家联盟概述了引入创新和高效的测序批量'干' AD系统，该系统由强大的辅助监测系统实现这将优化AD过程。这将在县得到支持，增加分析能力建设，以支持该项目和更广泛的反倾销部门，解决了AD系统的一个关键故障点-缺乏技术支持。这将为农村地区提供一条可负担得起的清洁能源之路，撒哈拉非洲通过利用高干物质和高纤维素废物。这种新颖的方法是系统地设计，以克服采用的关键障碍，来自废物进料的AD系统的能量的可持续性;资本成本、复杂性、运营成本和当地能力。AD系统将被设计为扁平封装系统，将在肯尼亚使用当地组件进行最终安装。在商业阶段，这使得该技术能够快速推广，同时项目开发商确保建设和IP的质量。该商业模式旨在通过供热和发电为废物提供价值，将这些服务出售给农业加工部门，这些部门在废物控制方面受到越来越多的立法，同时具有间歇性电力供应。多余的沼气将被干燥和压缩，并在当地社区用于烹饪，照明和冷却。这些创新将有助于克服能源三难困境，同时为企业和社区提供商业生态系统服务。
