“双碳”目标下济南市城市废旧资源循环利用研究

Research on the Recycling of Urban Waste Resources in Jinan City Under theCarbon Peaking and Carbon Neutrality

为响应我国“双碳”战略目标,城市废旧资源的循环利用成为有效途径。以济南市为研究对象,通过实地调研与问卷调查相结合的方式开展调查研究。结果表明:济南市城市工业固体废物产生量仍然会呈现不断上升趋势,但是增长率明显降低。而生活垃圾呈现波动上升趋势,济南市生活垃圾日处理能力将突破万吨,能够完全满足生活垃圾资源化、无害化处理需求。与此同时,济南市废旧资源循环利用仍存在诸多问题:工业企业循环利用主要存在废旧资源处理种类偏少、成本过高以及资源回收企业面临发展困境等问题;而生活垃圾的循环利用方面则存在垃圾分类认知不足、回收的认知、行为、意愿与回收利用设施之间不匹配,城市宣传力度不足、生活垃圾中部分可再生资源回收率低、垃圾分类的利益分配和责任分担有争议等主要问题。针对上述问题,从强化组织领导、强化要素支持、强化监管执法和强化宣传引导4个方面提出了相应对策建议。

In response to China's strategic goal of carbon peak and carbon neutrality,the recycling of urban waste resources has become an effective way.This paper takes Jinan City as the research object,and carries out the investigation and research through the combination of field research and questionnaire survey.It is found that the amount of municipal industrial solid waste generated in Jinan City will still show a rising trend,but the growth rate is significantly lower.While the domestic waste shows a fluctuating upward trend,the daily processing capacity of domestic waste in Jinan City will exceed 10000 t,which can fully meet the demand for resourceful and harmless treatment of domestic waste.At the same time,there are still a lot of problems in the recycling of waste resources in Jinan.The recycling of industrial enterprises is mainly due to the problems of fewer types of waste resources treatment,high costs and the development difficulties faced by resource recycling enterprises;while the recycling of domestic garbage is characterized by insufficient knowledge of garbage classification,mismatches among the knowledge,behavior and willingness to recycle and recycling facilities,insufficient publicity,and low recovery rates of some renewable resources in domestic garbage.The recycling of domestic waste is characterized by insufficient awareness of waste classification,a mismatch between awareness,behavior and willingness to recycle and recycling facilities,insufficient publicity in cities,a low recycling rate of some renewable resources in domestic waste,and disputes over the distribution of benefits and responsibility for waste classification.In view of the above problems,this paper puts forward corresponding countermeasures and suggestions in four aspects,namely,strengthening organizational leadership,strengthening elemental support,strengthening supervision and law enforcement,and strengthening publicity and guidance.
