从产业链的角度分析,塑料要有管理地用,才能可持续地用。完整的产业链要顾及三个层次:一是政策法规的方向性与强制性;二是科学技术的可行性与经济性;三是社会环境的接受性与可持续性。还必须考虑塑料的“立足之本”。塑料的“立足之本”是其赖以存在,赖以发展的根本,是其本身具有的或通过我们的努力而获得的。(1)节能减排——塑料质轻,生产容易,使用方便,可实现节能减排从产业链考虑,有诸多环节可以节能减排,比如:
From the industrial chain point of view, the plastic should be managed to use in order to be sustainable. A complete industrial chain should take into account three levels: First, the direction of policies and regulations and mandatory; Second, science and technology feasibility and economy; Third, the social environment of acceptability and sustainability. Must also consider the plastic “foothold ”. Plastic “foothold ” is the root of its existence, depends on the development of its own or through our efforts and obtained. (1) energy-saving emission reduction - plastic light weight, easy production, easy to use, can achieve energy-saving emission reduction Consideration from the industrial chain, there are many aspects of energy saving can be reduced, such as:
