ReWaste4.0 is an innovative and cooperative K-Project in the period 2017–2021. Through ReWaste4.0 the transformation of the non-hazardous mixed municipal and commercial waste treatment industry towards a circular economy has started by investigating and applying the new approaches of the Industry 4.0. Vision of the ReWaste4.0 is, among others, the development of treatment plants for non-hazardous waste into a “Smart Waste Factory” in which a digital communication and interconnection between material quality and machine as well as plant performance is reached. After four years of research and development, various results have been gained and the present review article summarizes, links and discuss the outputs (especially from peer-reviewed papers) of seven sub-projects, in total, within the K-project and discusses the main findings and their relevance and importance for further development of the waste treatment sector. Results are allocated into three areas, namely: contaminants in mixed waste and technical possibilities for their reduction as well as removal; secondary raw and energy materials in mixed waste and digitalization in waste characterization and treatment processes for mixed waste. The research conducted in ReWaste4.0 will be continued in ReWaste F for further development towards a particle-, sensor- and data-based circular economy in the period 2021–2025.

“ ReWaste4.0”项目—回顾

ReWaste4.0是2017年至2021年间一项创新且合作的K项目。通过ReWaste4.0，通过研究和应用工业4.0的新方法，已经开始将无害的市政和商业废物混合处理行业向循环经济的转型。ReWaste4.0的愿景之一是将无害废物处理厂发展为“智能废物工厂”，在该工厂中，实现了物料质量与机器以及工厂性能之间的数字通信和互连。经过四年的研究和开发，已获得了各种成果，本综述文章总结，链接和讨论了七个子项目的成果（尤其是来自同行评审的论文），在K项目中进行讨论，并讨论主要发现及其对废物处理行业进一步发展的相关性和重要性。结果分为三个领域，即：混合废物中的污染物以及减少和清除污染物的技术可能性；混合废料中的次要原材料和能源材料，以及在废料表征和混合废料处理过程中进行数字化。在ReWaste4.0中进行的研究将在ReWaste F中继续进行，以便在2021-2025年期间进一步发展为基于粒子，传感器和数据的循环经济。混合废料中的次要原材料和能源材料，以及在废料表征和混合废料处理过程中进行数字化。在ReWaste4.0中进行的研究将在ReWaste F中继续进行，以便在2021-2025年期间进一步发展为基于粒子，传感器和数据的循环经济。混合废料中的次要原材料和能源材料，以及在废料表征和混合废料处理过程中进行数字化。在ReWaste4.0中进行的研究将在ReWaste F中继续进行，以便在2021-2025年期间进一步发展为基于粒子，传感器和数据的循环经济。
