Many organizations in Europe collect data and perform research on municipal solid waste and the secondary raw materials that can be produced from them through recycling, urban mining, or landfill mining. However, the information generated and presented thereby is often highly aggregated, while research activities are many a time isolated. Both reduce the usability of the data and information generated. In order to better structure the knowledge generation on secondary raw materials production from municipal solid waste, we suggest to learn from the traditional raw materials mining industry how to perform an integrated assessment and reporting of anthropogenic resources. This is exemplarily shown for the case of the anthropogenic resource municipal solid waste incineration bottom ash and air-pollution control residues. A network of expert institutions from countries throughout Europe was build up to compile the information on legal and technological aspects for the recovery of different secondary raw materials from these residues, including construction minerals, metals, and salts. We highlight in our article the strength of the combined knowledge of an expert network not only on legal and technological, but also local and site-specific aspects of the recovery of secondary raw materials. By doing so, we hope to kick-off a discussion for how to organize and implement a structure for a better management of knowledge on anthropogenic resources, in order to provide a sustainable supply of secondary raw materials for a greener and more circular economy.

欧洲的许多组织收集数据，并对市政固体废物和可通过回收，城市采矿或垃圾掩埋开采产生的次级原料进行研究。然而，由此产生和呈现的信息通常是高度聚合的，而研究活动往往是一次孤立的。两者都会降低所生成数据和信息的可用性。为了更好地构建有关城市生活垃圾二次原料生产的知识生成，我们建议向传统原料采矿行业学习如何对人为资源进行综合评估和报告。对于人为资源城市固体废物焚烧底灰和空气污染控制残留物的情况，示例性地显示了这一点。建立了来自欧洲各国的专家机构网络，以收集有关法律和技术方面的信息，以便从这些残留物中回收不同的二级原材料，包括建筑矿物质，金属和盐。我们在文章中强调了专家网络的综合知识的力量，不仅在法律和技术上，而且在二级原料的回收方面还具有本地和特定地点的方面。通过这样做，我们希望就如何组织和实施更好地管理人为资源知识的结构展开讨论，以便为绿色和循环经济提供可持续的二次原料供应。
