Proper resources recycle or reuse planning helps the industrial sites to reduce reliance on raw resources. There are a lot of previous researches that had applied the Pinch Analysis on the resources recycling problem. However, there is not much work completed on targeting the materials headers or mains from the sources of the plants. This work extends the Material Recovery Pinch Diagram to provide an insightful yet straightforward approach to targeting the material headers/mains with minimum fresh resource consumption (e.g. water, hydrogen or CO₂) with single quality. The flowrates and the concentration of the exchanged streams in the material headers, as well as the minimum number of headers, can be targeted using a Pinch-based strategy, which can be applied at either process or Total Site scale. This study also proposes a novel algorithm to minimise the cross-plant material source transfer for the Total Site material network with header/mains design while ensuring the overall minimum fresh resource target is satisfied. A Source Transfer Diagram is proposed to identify optimal reuse opportunities of the purged sources from individual plants. A case study is used to demonstrate the proposed framework, comparing results obtained using direct integration and centralised headers. The benefits of this framework are two-fold. It provides the minimum resource consumption rates for the overall network, and it also enables the network and mains/header design through graphical visualisation, which is a non-linear problem. The graphical interface allows users to explore different source mixing options from individual plants while ensuring the number of headers, resource consumptions, and cross-plant source transfer are minimal.

正确的资源回收或再利用计划可帮助工业现场减少对原始资源的依赖。以前有很多研究将捏捏分析应用于资源回收问题。但是，针对来自工厂来源的物料集管或干线的工作还很少。这项工作扩展了材料回收捏合图，从而提供了一种有见地而又简单明了的方法，以最少的新鲜资源消耗（例如水，氢或CO _2）为目标的材料集管/主管。），质量单一。物料集管中交换流的流量和浓度以及集管的最小数量，可以使用基于Pinch的策略作为目标，该策略可以在过程规模或总站点规模上应用。这项研究还提出了一种新颖的算法，可以在使用总管/主管设计的同时，最大程度地减少跨站点物料网络的跨工厂物料源转移，同时确保满足整体最低的新鲜资源目标。建议使用“源转移图”来确定从各个工厂清除的源的最佳重用机会。案例研究用于演示提出的框架，比较使用直接集成和集中式标头获得的结果。该框架的好处有两方面。它为整个网络提供了最低的资源消耗率，并且还通过图形可视化实现了网络和电源/头设计，这是一个非线性问题。图形界面允许用户探索来自各个工厂的不同源混合选项，同时确保最小数量的标题，资源消耗和跨工厂源转移。
