The　industrial　sector　is　the　primary　source　of　carbon　emissions　in　China.　In　pursuit　of　meeting　its　carbon　reduction　targets,　China　aims　to　promote　resource　consumption　sustainability,　reduce　energy　consumption,　and　achieve　carbon　neutrality　within　its　processing　industries.　An　effective　strategy　to　promote　energy　savings　and　carbon　reduction　throughout　the　life　cycle　of　materials　is　by　applying　life　cycle　engineering　technology.　This　strategy　aims　to　attain　an　optimal　solution　for　material　performance,　resource　consumption,　and　environmental　impact.　In　this　study,　five　types　of　technologies　were　considered:　raw　material　replacement,　process　reengineering,　fuel　replacement,　energy　recycling　and　reutilization,　and　material　recycling　and　reutilization.　The　meaning,　methodology,　and　development　status　of　life　cycle　engineering　technology　abroad　and　domestically　are　discussed　in　detail.　A　multidimensional　analysis　of　ecological　design　was　conducted　from　the　perspectives　of　resource　and　energy　consumption,　carbon　emissions,　product　performance,　and　recycling　of　secondary　resources　in　a　manufacturing　process.　This　coupled　with　an　integrated　method　to　analyze　carbon　emissions　in　the　entire　life　cycle　of　a　material　process　industry　was　applied　to　the　nonferrous　industry,　as　an　example.　The　results　provide　effective　ideas　and　solutions　for　achieving　low　or　zero　carbon　emission　production　in　the　Chinese　industry　as　recycled　aluminum　and　primary　aluminum　based　on　advanced　technologies　had　reduced　resource　consumption　and　emissions　as　compared　to　primary　aluminum　production.　©　2024　Chinese　Academy　of　Engineering
