Transitioning to future circular economies and food systems will increase demand for biomass in society. Residual streams, which include food loss, food waste and by-products (e.g., rapeseed meal) from agriculture and food production are a valuable source of biomass in more circular food systems. It is currently unclear if and whether these residual streams should be utilised optimally: as animal feed, composted as organic fertiliser or for anaerobic digestion to produce biogas (methane) and digestate (fertiliser) to minimise environmental impacts from food systems.

如何在循环食品系统中利用残留的生物质流来最大限度地减少土地使用或温室气体排放


向未来的循环经济和食品系统过渡将增加社会对生物质的需求。在循环性更强的食品系统中，包括食物损失、食物浪费和副产品（例如菜籽粕）在内的残留流是生物质的宝贵来源。目前尚不清楚是否应该以最佳方式利用这些残余流：作为动物饲料，作为有机肥料堆肥或用于厌氧消化以产生沼气（甲烷）和沼渣（肥料），以最大限度地减少食品系统对环境的影响。
