Global glass production grew to 150 million tonnes (Mt) in 2014, equating to approximately 21 kg per person. Producing this glass is energy intensive and contributes annual CO2 emissions of some 86Mt. An accurate map of the global glass supply chain is needed to help identify emissions mitigation options from across the supply chain, including process energy efficiency and material efficiency options. This map does not yet exist, so we address this knowledge gap by tracing the production chain from raw materials to end of life and producing a global Sankey diagram of container and flat glass making for 2014. To understand future demand for flat glass we also model the stocks of glass in vehicles and buildings. The analysis shows the relative scale of glass flows and stocks worldwide and provides a baseline for future study of the emission mitigation potential of energy and material efficiency of manufacturing with glass.

玻璃的全球物料流分析:从原材料到报废

2014年,全球玻璃产量增长至1.5亿吨(Mt),相当于每人约21公斤。生产这种玻璃需要消耗大量能源,并且每年会产生CO 2排放约86Mt。需要准确的全球玻璃供应链地图,以帮助确定整个供应链中的减排方案,包括工艺能效和材料效率方案。该地图尚不存在,因此我们通过追踪从原材料到报废的生产链并生成2014年全球Sankey容器和平板玻璃制造图来解决这一知识鸿沟。为了解平板玻璃的未来需求,我们还进行了建模车辆和建筑物中的玻璃库存。该分析显示了全球玻璃流量和库存的相对规模,并为将来研究使用玻璃制造的能源和材料效率的排放缓解潜力提供了基线。
