Reducing contamination risk and increasing yields in the production of platform sugars from UK MSW

Fiberight创建了一个循环经济解决方案，从垃圾固体废物（MSW）中产生增值产品。该过程包括热机械处理和洗涤城市固体废物，以回收两个主要部分：可回收物和生物质。洗涤阶段产生含有可溶性有机物的洗涤水，其可以是高速厌氧消化器的进料，以产生沼气，可再生能源的来源。洗涤后的残余固体是富含木质纤维素纤维的“清洁”生物质，可以通过酶水解转化为糖：这些糖在基于废物的工业生物精炼厂中形成了各种产品的构建模块。该项目将测试新的方法，包括在城市固体废物洗涤阶段使用专门的添加剂，以改善洗涤纤维素纤维的质量并提高其糖产量，以及一种新的低成本pH控制剂，以减少食物废物和营养物质污染的风险，影响下游糖生产阶段。

Fiberight has created a circular economy solution to generate value-added products from municipalsolid waste (MSW). The process involves thermo-mechanically treating and washing the MSW to recovertwo main fractions: recyclables and biomass. The washing stage generates a washwater containingsoluble organic matter which can be a feed for high-rate anaerobic digesters to produce biogas, a sourceof renewable energy. The residual solid from washing is a 'clean' biomass rich in lignocellulosic fibre thatcan be converted into sugars via enzyme hydrolysis: these sugars form the building blocks for a widerange of products in a waste-based industrial biorefinery. The project will test novel methods includingthe use of specialised additives in the MSW washing stage to improve the quality of the washedcellulose fibre and increase its sugar yield, and a new low-cost agent for pH control, to reduce the risksof contamination from food waste and nutrients affecting the downstream sugar production stage.
