As part of the EU Life + NOVEDI project, a new eco-efficient recycling route has been implemented to maximise resources and energy recovery from post-consumer waste glass, through integrated waste management and industrial production. Life cycle assessment (LCA) has been used to identify engineering solutions to sustainability during the development of green building products. The new process and the related LCA are framed within a meaningful case of industrial symbiosis, where multiple waste streams are utilised in a multi-output industrial process. The input is a mix of rejected waste glass from conventional container glass recycling and waste special glass such as monitor glass, bulbs and glass fibres. The green building product is a recycled foam glass (RFG) to be used in high efficiency thermally insulating and lightweight concrete. The environmental gains have been contrasted against induced impacts and improvements have been proposed. Recovered co-products, such as glass fragments/powders, plastics and metals, correspond to environmental gains that are higher than those related to landfill avoidance, whereas the latter is cancelled due to increased transportation distances. In accordance to an eco-efficiency principle, it has been highlighted that recourse to highly energy intensive recycling should be limited to waste that cannot be closed-loop recycled.
作为欧盟 Life + NOVEDI 项目的一部分，通过综合废物管理和工业生产，实施了一种新的生态高效回收途径，以最大限度地从消费后废玻璃中回收资源和能源。生命周期评估 (LCA) 已被用于在绿色建筑产品的开发过程中确定可持续性的工程解决方案。新工艺和相关的 LCA 是在有意义的工业共生案例中提出的，其中多个废物流在多产出的工业过程中得到利用。输入是传统容器玻璃回收中废弃的废玻璃和监视器玻璃、灯泡和玻璃纤维等特殊废玻璃的混合物。绿色建筑产品是一种再生泡沫玻璃 (RFG)，用于高效隔热和轻质混凝土。已对比了环境收益与诱导影响，并提出了改进措施。回收的副产品，如玻璃碎片/粉末、塑料和金属，对应于高于与避免垃圾填埋相关的环境收益，而后者因运输距离增加而被取消。根据生态效率原则，强调应将对高能耗回收的依赖限制在无法进行闭环回收的废物上。
