Industrial symbiosis (IS), where different entities collaborate in the management of energy, utilities, materials, or services, has been identified as an approach to improve resource efficiency and circularity in industry. This article assesses the environmental performance of an IS network with firms involved in waste management, soil, surfaces, paper, lumber, and energy. The aim is to highlight the environmental performance of an IS network and pay particular attention to the improved performance for products in the IS network. Life cycle assessment is used to compare the current IS network with a reference scenario and a potential future development. The results suggest that there are significant benefits from the IS network. Large reductions in greenhouse gas (GHG) emissions and abiotic resource depletion were identified. Furthermore, large reductions in local impacts, namely eutrophication and acidification impacts are illustrated. It was shown that all firms in the network benefit from the synergies involved, with a large share of the benefits stemming from the facilitated exchanges with the waste management company. The replacement of conventional products and energy streams with bio‐based counterparts from within the network is of significant importance. Finally, the results point to the importance of the facilitation of by‐product synergies, and the significant value this creates in the region, with large potential to improve the environmental performance of firms and their products.

评估通过工业共生生产土壤和表面的环境绩效

工业共生（IS）由不同的实体在能源，公用事业，材料或服务的管理方面进行协作，已被认为是提高工业中资源效率和循环性的一种方法。本文评估了与废物管理，土壤，表面，纸张，木材和能源相关的公司组成的IS网络的环境绩效。目的是强调IS网络的环境性能，并特别注意IS网络中产品的性能提高。生命周期评估用于将当前的IS网络与参考方案和潜在的未来发展进行比较。结果表明，IS网络有很多好处。确定了温室气体（GHG）排放量的大幅减少和非生物资源的消耗。此外，说明了局部影响的大幅度减少，即富营养化和酸化影响。结果表明，网络中的所有公司都受益于所涉及的协同作用，其中很大一部分收益来自与废物管理公司进行便利的交流。从网络内部用基于生物的对应物替代传统产品和能源流非常重要。最后，结果表明了促进副产品协同增效的重要性，以及在该地区创造的巨大价值，具有改善企业及其产品的环境绩效的巨大潜力。与废物管理公司进行便利的交流带来的巨大收益。从网络内部用基于生物的对应物替代传统产品和能源流非常重要。最后，结果表明了促进副产品协同增效的重要性，以及在该地区创造的巨大价值，具有改善企业及其产品的环境绩效的巨大潜力。与废物管理公司进行便利的交流带来的巨大收益。从网络内部用基于生物的对应物替代传统产品和能源流非常重要。最后，结果表明了促进副产品协同增效的重要性，以及在该地区创造的巨大价值，具有改善企业及其产品的环境绩效的巨大潜力。
