Unlike other available inventory tools, this tool aimed at including environmental assessment features, that would allow warehouse managers to have an estimation of their environmental contribution associated to their sales performance without having to engage environmental experts regularly. The resulting open source software allows to keep an inventory of items available at the warehouse, export to an online shop and generate reports of the sales and environmental benefits of reusing some of the secondary materials sold. This article explains how the tool was developed, how the simplified LCA calculations were done and integrated to the tool, the difficulties encountered when compromising ease of use with the need for reliable data to do the environmental calculations, and reflects on the reliability and scalability of the developed tool.en500 Naturwissenschaften und Mathematik600 Technik, Technologie338 Produktionsecondary materialsUrban Resource Centressimplified LCA integrated to a digital inventory toolopen sourceIdematonline catalogueArticle2022-09-161755-1315
