Using Bottom-up Approach And Material Flow Analysis In Is Mode Of Solid Waste Utilization In Textile And Garment Industry

The light industry and building materials industry are the characteristic industries agglomerated in the region of southeast in China.However,the low quality utilization and low recovery rate of solid waste in the region requires to deplor an efficient development model of circular economy.The comprehensive utilization of solid waste performed in the textile and garment industry,leather shoes industry and stone processing industry as a group is an important way to solve the problems of environmental pollution in the southeast region.However,considering that the comprehensive utilization of solid waste via regional group involving many management lines with great uncertainty,needing multi-sectoral coordination and being difficult to achieve full coverage of the three major industries,in the study,the textile and garment symbiosis mode was employed as the main line in the group.Focusing on the dual environmental management objectives of multi-source solid waste collaborative disposal and industrial symbiosis,the pattern recognition and evaluation methods were modified,and an effective popularization was established.The application mechanism is an important breakthrough to give full play to the leading role of the textile and garment industry,and to promote the innovation of solid waste consumption mode in light industrial building materials from point to area.The bottom-up modeling(bottom-up approach referred to as ’ BU ’)was employed to study the symbiotic mode of textile and garment.And based on the ecological and environmental benefits assessment,the textile and garment industry coordinates the demands of various solid waste objects and types in resource recycling were analyzed to provide a theoretical basis for building a regional group of solid waste comprehensive utilization of green technology integrated innovation system.The traditional bottom-up modeling method is mainly applied to the study of energy policy and pollutant emission reduction.The methodology developed in this study proposes to apply it to the construction of industrial symbiosis network,breaking the limitations of the previous implementation of cleaner production technology by single project and single enterprise.In order to establish a mode of solid waste collaborative symbiosis utilization in the agglomeration area,which can be copied and extended,this paper summarizes the production of polyester filaments for textiles using r-PET bottles as raw materials.The production of zipper monofilament for textiles using PET waste textiles as raw materials.The production of polyester filament for textiles using r-PET bottle piece and polyester waste silk as raw materials.The production of reinforced monofilament for inorganic artificial stone using polyester waste silk as raw materials.The production of recycled fiber for nonwoven textiles using scrap corner as raw materials.Fiber-source unsaturated resin was produced from waste corner materials for organic artificial stone.Collaborative disposal and utilization of loose fiber debris,PU precursor and active rubber powder.Eight symbiotic modes of textile and garment for producing fiber-plastic composites with r-PE or r-PP as continuous phase and PET waste textile as reinforcing agent.On this basis,to carry out the Quanzhou demonstration city textile industry symbiosis network application mechanism research.The results show that the carbon emission reduction benefits of recycled materials replacing raw materials are significant,and it is necessary to construct the symbiosis paradigm of China’ s textile and garment industry.Through the popularization and application of the symbiosis model of Baichuan-Pengxiang-Sanjing enterprise group,nearly zero emissions can be achieved.
