Scalable Circular Supply Chain For the Built Environment

该项目将展示英国最大的行业之一如何利用数字平台来利用可持续循环供应链的好处，以减少浪费，提高安全性，并促进更大的财政责任。建筑，工程和建筑（AEC）部门在英国经济中发挥着至关重要的作用，雇用了200多万人来提供支撑我们经济增长的土木工程项目。作为GDP的最大贡献者之一，ACE行业代表着从个体承包商到跨国公司的商业活动，这些企业通过复杂的资产分销网络进行合作，贸易额超过100亿英镑。这个活动网络消耗数百万吨材料，产生的废物比所有其他行业的总和还要多。部分原因是无法保持对材料使用的行业广泛了解。由于密集的人工成本，填海占工业活动的一小部分，并且仅对于高成本，通常具有历史价值的材料具有经济可行性。因此，一个关键的挑战是不仅需要回收，而且需要在整个生命周期内跟踪所有材料/资产的使用情况。我们的方法是建立一个数字平台，并评估相关的商业模式，在该模式下，建筑环境可以提供材料的跟踪，而无需逃避建筑检查，以进行召回和恢复活动。研究的主要成果将是：1.一个数字（软件）平台，利用多层区块链的潜力，平衡交易记录/管理的本地自主权，同时在AEC生命周期的每个阶段保持记录活动的一致来源跟踪。“材料和服务护照”的概念和实施，以显示材料/组件/资产/服务的循环潜力，并使利益相关者（例如设计师，主承包商，制造商和客户）能够评估循环的可能性。3.基于（与行业）共同开发的数字平台和循环供应链模型的路线图，以激励集体供应链行为实现循环经济和环境可持续性。

This project will demonstrate how one of the largest industries in the UK can utilise a digital platform to harness the benefits of a sustainable circular supply chain, so as to reduce waste, increase safety, and promote greater fiscal responsibility. The Architecture, Engineering & Construction (AEC) sector plays a crucial role in the UK economy by employing over 2 million people to deliver civil engineering projects that underpin our economic growth. One of the biggest contributors to GDP, the ACE sector represents commercial activity spanning individual contractors through to multi-national corporations collaborating through complex asset distribution networks that account for over £10 billion of trade.This network of activity consumes millions of tonnes of materials and produces more waste than all other industries combined, partly due to an inability to maintain an industry wide knowledge of material usage. Reclamation accounts for a fraction of industry activity due to intensive manual costs and is only economically viable for high cost, often historically valuable, materials. A key challenge therefore is a need to not only reclaim, but to track all material/asset usage throughout their lifecycles. Our approach is to build a digital platform and assess the associated business models within which the built environment can provide the tracing of materials without evasive building inspections for recall and resume activity.The main outcomes of the research will be: 1. A digital (software) platform that harnesses the potential of multi-layered blockchains, to balance local autonomy of transaction recording/management, whilst maintaining a consistent provenance trail of recorded activity within each stage of the AEC lifecycle.2. The concept and implementation of a 'material & service passport' to show the circularity potential of materials/ components/ assets/ services and enable stakeholders (e.g. designers, main contractors, manufacturers and clients) to assess the likelihood for circularity. 3. A road map based on the co-developed (with industry) digital platform and circular supply chain models, to incentivise collective supply chain behaviours towards circular economy and environmental sustainability.
