Full lifecycle-based sustainability evaluation for remanufacturing ecosystem service:A novel perspective of technology-ecology synergy

Ecosystems play a very important role in the sustainable development of remanufacturing. Research has often focused on the sustainability of remanufacturing systems from the aspect of general technological activities, for which there is a lack of an in-depth consideration of ecological services. This may lead to an imbalanced development of ecosystems. This paper proposes a full lifecycle-based sustainability evaluation model for remanufacturing ecosystem services (ESs) from the novel perspective of technology-ecology synergy. Firstly, by analyzing the coupling effect of technical activities and ecological services, a technology-ecology synergy in a lifecycle assessment (TES-LCA) computing model is established to quantify the sustainability of remanufacturing ESs. Secondly, the supply and allocation of ESs considering multiple users are proposed and addressed. Thirdly, regional differences in ESs are investigated. The sustainability of ESs is then analyzed and calculated on a multi-spatial scale. Finally, the feasibility of the proposed model is verified by performing a case analysis of the remanufacturing of a spindle of a machine tool that is to be adopted in two regions. The case study results showed that the air quality control service in both two regions is unsustainable; however, the water supply service is sustainable. The proposed model can provide data support for governmental policy makers and businesses to formulate relevant policies to maintain a balanced development of ecosystems
