Decarbonising Precast Concrete Manufacturing

**脱碳预制混凝土制造**项目旨在为Laing O‘Rourke位于Worksop的Steetley的探索制造现有预制混凝土生产流程实施深度脱碳干预措施提供全面的可行性研究。**战略重点--脱碳建筑**探索制造代表了建筑业非现场制造的最先进水平。政府到2025年的建筑业战略和建筑业交易的目标都是在建筑环境中实现更高的预制价值和50%的碳减排，以及2030年的净零目标。有必要进一步提供长期的脱碳机会，以满足这一战略方向。建筑业占英国GDP的6%，建筑环境贡献了所有温室气体排放的39%，特别是总排放量的11%来自资产建设[2017年全球状况报告]，因此碳强度将对英国的整体碳使用产生重大影响。将混凝土建筑生产从现场转移到异地(预制件)立即对降低建筑物中的碳含量产生重大影响；此外，我们正寻求通过预制件制造过程的深度脱碳进一步提高这一影响，预计可节省约56%的总成本。**全面和系统的可行性评估**我们的项目将调查生产过程的方方面面，从低碳、混凝土、钢铁和骨料材料和技术到整体模板和养护系统。这一初始范围将对预制生产过程的脱碳干预措施进行量化、优先排序和定义，然后将对这些干预措施进行可行性试验，包括采用低碳材料和生产技术以实现制造过程的脱碳。已确定技术的例子包括低碳混凝土、再生钢筋、再生骨料和替代骨料以及模板系统。这些试验将考虑对材料供应、处理、生产线的材料和技术引入、包括养护时间在内的生产能力考虑以及其他存储和物流问题的影响。可行性研究将以探索制造公司脱碳预制混凝土施工的影响优先路线图和商业案例结束。这将为行业中的其他公司提供一个复制从而扩大影响的旗舰范例。**高质量团队**这项研究将由Laing O‘Rourke领导，基于我们的探索制造设施，与以下合作伙伴合作：\*剑桥大学--领导碳量化和脱碳影响优先排序\*谢菲尔德大学，先进制造研究中心(AMRC)--过程影响模拟，以了解干预措施对产能和生产率的影响

The **Decarbonising Precast Concrete Manufacturing** project is to deliver a comprehensive feasibility study for implementing deep decarbonisation interventions at Laing O'Rourke's Explore Manufacturing existing precast concrete production process, based at Steetley, Worksop.**Strategic priority -- decarbonising construction**Explore Manufacturing represents the state of the art in offsite manufacturing for the construction industry. Government strategy through Construction 2025 and the Construction Sector Deal targets both higher pre-manufactured value and 50% carbon reduction in the built environment as well as a Net Zero 2030 target. There is significant need to further enable long-term decarbonisation opportunities to meet this strategic direction. Construction represents 6% of UK GDP and the built environment contributes 39% of all greenhouse emissions, specifically 11% of the total being upfront embodied carbon from construction of assets {Global Status Report 2017\], so carbon intensity will make a significant impact on overall carbon usage in the UK. Moving concrete building production from in situ to offsite (precast) immediately has a significant impact on lowering embodied carbon in buildings; moreover we are seeking to increase this further by deep decarbonisation of the precast manufacturing process offering anticipated total savings of some 56% .**Comprehensive and systematic feasibility review**Our project will investigate every facet of the production process from low carbon, concrete, steel and aggregate materials and technologies to the overall formwork and curing systems. This initial scoping will quantify, prioritise and define interventions for decarbonisation of the precast production process and will then conduct feasibility trials for these interventions, including incorporation of low carbon materials and production technologies to decarbonise the manufacturing process. Examples of identified technologies include low carbon concrete, recycled reinforcement, recycled and alternative aggregates, and formwork systems. These trials will consider implications into materials supply, handling, materials and technology introduction to production line, throughput considerations including curing time, and other storage and logistics issues.The feasibility study will conclude with an impact prioritised roadmap and business case for decarbonising precast concrete construction at Explore Manufacturing. This will provide a flagship example to others in the industry to replicate thus widening the impact.**High quality team**The study will be led by Laing O'Rourke, based on our Explore Manufacturing facility, in collaboration with the following partners:\*University of Cambridge -- leading the carbon quantification and decarbonisation impact prioritisation\*University of Sheffield, Advanced Manufacturing Research Centre (AMRC) -- process impact simulation to understand throughput and productivity implications of interventions
