The paper presents an extension of Pinch Analysis and namely, Total Site Process Integration. It benefits from up to date developments and introduction of Total EcoSite Integration for urban and industrial symbiosis. An important development is Pinch Analysis for Solid Waste Integration which is a crucial step for the symbiosis in a circular economy. As the potential EcoSites are usually extensive and cover various units, a methodology based on clusters has been used. The solution has been supported by graphical tools using the analogy with already implemented extensions of Pinch Analysis. The results of a demonstration case study revealed the potential of the novel approach. The identified integrated design increased the energy recovered from the solid waste by 11.39 MWh/d and diverted 2 t/d of the waste from the landfill, benefiting both the urban and industrial site. The proposed approach is also capable of minimising the requirement of energy-intensive thermal drying for waste whenever the process allowed, subsequently offer a solution with lower environmental footprint and cost. For future work, a even more comprehensive case study can be conducted by considering the other forms of the waste, recovery process and drying approaches.
本文提出了一种夹点分析的扩展，即总厂区过程集成。它受益于最新的发展和引入的城市和工业共生的总生态厂区集成。一个重要的发展是固体废物集成的夹点分析，这是循环经济共生的关键步骤。由于潜在的生态厂区通常很广泛，涵盖了各种单元，因此使用了基于集群的方法。该解决方案得到了使用类比已经实现的夹点分析扩展的图形工具的支持。一个演示案例研究的结果显示了新方法的潜力。所确定的综合设计将从固体废物中回收的能源增加了 11.39 MWh/d，并将 2 吨/天的废物从垃圾填埋场转移出去，使城市和工业厂区都受益。所提出的方法还能够在工艺允许的情况下尽量减少对能源密集型热干燥的需求，从而提供一种具有更低环境足迹和成本的解决方案。对于未来的工作，可以通过考虑其他形式的废物、回收过程和干燥方法，进行更全面的案例研究。
