华南典型废塑料循环技术综合绩效评价

COMPREHENSIVE PERFORMANCE EVALUATION OF TYPICAL WASTE PLASTIC RECYCLING TECHNOLOGIES IN SOUTH CHINA

我国华南地区废塑料循环利用技术种类众多,尚未形成多元循环技术综合绩效对比分析的方法体系。以华南地区废聚丙烯(PP)为例,构建了废PP循环技术的环境-经济综合绩效评价计算方法。综合绩效结果表明,改性再生技术具有最高的综合绩效。华南地区各循环技术的综合绩效对比结果表明,应对降级利用技术进行升级,减少化学裂解与焚烧发电技术的市场占比,以达到华南地区最高的综合绩效。为此,相关行业应扩大对改性再生技术的宣传,提高该技术在废塑料循环市场的占有率。此外,政府应通过相关推广政策、加大循环工艺设施财政投入,将降级利用技术升级为改性再生技术,一方面提高技术应用企业的经济绩效,另一方面减少华南地区间的环境污染成本。

There are many types of waste plastic recycling technologies in South China, and a method system for comprehensive performance of multiple recycling technologies has not been formed. This study intends to take waste polypropylene(PP) in South China as an example to construct an environmental-economic comprehensive performance evaluation method for waste plastic recycling technology. The comprehensive performance results show that the modified regeneration technology has the highest comprehensive performance. The comparison results of various recycling technologies in South China indicate that the use of degraded technologies should be upgraded to reduce the market share of chemical cracking and incineration power generation technologies to achieve the highest comprehensive performance in South China. Based on this, relevant industries should expand the promotion of modified recycling technology and increase the usage rate of the waste plastic recycling market. In addition, the government should adopt relevant promotion policies and increase financial investment in recycling process facilities to upgrade degraded utilization to modified regeneration. It will not only improve the economic performance of technology application enterprises, but also reduce the cost of environmental pollution in South China.
