为了实现到 2050 年工业二氧化碳排放量减少 50% 的目标，必须削减对钢铁和铝的需求。许多钢和铝产品都包含多余的材料，并且生产它们的制造路线使用的材料超过了必要的材料。轻量化设计和优化的制造工艺提供了一种减少需求的方法，同时创造出与现有产品提供相同服务的产品。本文探讨了减少需求的两种策略：轻量化产品设计；并通过产品供应链最大限度地减少产量损失。针对工字钢和食品罐等金属密集型产品的具体案例研究，估计了可能节省的质量。然后将这些估计值外推到其他部门，以得出对可能的需求减少的全球估计值。结果表明，轻量化产品设计可能会为某些产品节省高达 30% 的质量，而其他产品的产量可能会提高 20% 以上。如果这两种策略可以...
To meet targeted 50% reductions in industrial CO2 emissions by 2050, demand for steel and aluminium must be cut. Many steel and aluminium products include redundant material, and the manufacturing routes to produce them use more material than is necessary. Lightweight design and optimized manufacturing processes offer a means of demand reduction, whilst creating products to perform the same service as existing ones. This paper examines two strategies for demand reduction: lightweight product design; and minimizing yield losses through the product supply chain. Possible mass savings are estimated for specific case‐studies on metal‐intensive products, such as I‐beams and food cans. These estimates are then extrapolated to other sectors to produce a global estimate for possible demand reductions. Results show that lightweight product design may offer potential mass savings of up to 30% for some products, whilst yield in the production of others could be improved by over 20%. If these two strategies could be ...
