Experience and enlightenment of recycling system of packaging waste in Europe

As economy explodes and packaging industry flourishes, it is a critical issue that international community encounters the waste of resources and environmental pollution caused by packaging waste. As far as the Packaging Waste Management is concerned, European countries are abundant in worthwhile experiences, which could be used for reference to China＇s Construction of Packaging Waste Recycling System. Based on the analysis of industrial chain of European Packaging Waste Recycling System, this paper illuminates the corresponding policies, managements and role of distinguished interest-individual in different stages, which administers suggestions on how to put forward policies and implementing ordinance to China＇s Packaging Waste Management.

报废汽车回收体系结构模型研究

报废汽车的回收重用一方面是＂生产者责任延伸制＂在汽车行业贯彻实施的结果,另一方面来源于再制造环节中蕴藏的丰厚利润的诱导.目前我国回收利用报废汽车的方式比较落后,主要是对原材料进行重用.本文构建了一个由汽车制造商牵头纽建,以功能多样化的回收中心作为中心处理单元的报废汽车回收体系结构模型,以期实现更高层次的回收重用.

我国城市建筑垃圾资源化现状及对策研究

随着我国基础设施的大规模建设以及城镇化进程的快速推进,建筑垃圾的产生量日益增多。建筑垃圾资源化作为解决当前环境问题的一种有效途径,对实现资源的优化配置以及经济社会的可持续发展具有重要意义。论文首先阐述了建筑垃圾资源化的基础理论,并采用建筑面积估算法对我国城市建筑垃圾的产生量进行了估算,进而分析了我国建筑垃圾资源化的现状,并提出了实现建筑垃圾资源化的具体对策。     

产品包装废弃物的污染与回收利用

产品包装废弃物对生态环境产生严重影响：使城市的生态环境污染加剧．占用大量的耕地，使蚊蝇滋生，造成资源的大量浪费。产品包装废弃物的回收与利用可产生巨大的经济效益和社会效益，但必须解决如下几个问题：地方政府职能缺位、法律体系不健全和有法不依、国民环境意识淡薄及企业社会责任缺失。     

Design concept for the solid waste landfill site： a case study of Chuzhou City, China

1. Introduction Domestic waste has become a worldwide hazard. It has been listed in Preferential Programmes in China for 21st Century. The combination of the three techniques, the transformation of domestic waste into useful resources, the reduction of do- mestic waste and the innocent treatment of domes- tic waste is the long-term guideline in China. In the spirit of the guideline, several laws and regulations have been enacted, including Technical Standards of Municipal Solid Landfill, …     

建筑垃圾处理与循环经济

建筑垃圾对环境的影响以及对建筑垃圾的资源化利用已成为亟待研究和解决的问题。循环经济把经济活动组成一个“资源一产品一再生资源”的反馈式流程,从而最大限度地减少经济活动对生态环境的影响。通过对建筑垃圾分类、组成和我国目前在处理方法上存在问题的分析,提出应用循环经济的“3R原则”资源化处理建筑垃圾的对策。     

Forcing Firms to Think About the Future: Economic Incentives and the Fate of Hazardous Waste

What is the cost of off-site hazardous waste disposal? In addition to paying for disposal fees and shipments costs, generators of hazardous waste can potentially be held liable for the cost of cleanup if the waste disposal site contaminates the environment after closure or abandonment and thus falls under the federal or state Superfund legislation. This paper empirically examines the sensitivity of individual hazardous waste generators to these categories of costs, exploiting the variation across states in factors influencing disposal costs, and in the structure of the liability imposed on waste generators under certain circumstances by state laws. We fit nested logit models to predict the waste management method (incineration or landfill disposal) and the state of destination for shipments of halogenated solvent waste used for metal cleaning in manufacturing and reported in the Toxic Release Inventory in 1988–1990. Waste generators respond to transportation costs and to proxies for current disposal costs. Generators also find the concurrent presence of strict and joint-and-several liability a deterrent, but this deterrent effect does not vary with the wealth of the firm or the volume of the waste shipped.     

论废弃产品问题与生产者责任延伸制度的回应

产品在消费后阶段所凸显的环境污染与资源浪费问题,即废弃产品问题,源于产品的资源性和潜在污染性,自然处置方式的不能和焚烧、填埋处置方式的不当。生产者责任延伸制度概念的提出为废弃产品问题的解决找到了合理的责任承担主体,减轻了政府在此方面的责任,为通过立法建立具体的生产者责任延伸制度提供了雏形。建立生产者责任延伸制度,施行回收处置方式是破解废弃产品问题的制度回应。
