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, … 相似文献

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. 相似文献

论废弃产品问题与生产者责任延伸制度的回应 总被引:1,自引:0,他引:1
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。 相似文献

Studies have demonstrated the inadequacy of relying on existing administrative boundaries or simple proximity to define an affected community. The proposal and siting of hazardous facilities can have a range of impacts upon people across wide areas, with some more affected than others as a result of living with the physical impacts of construction or the fear associated with perceived risk. We term those most affected the directly affected population and propose a two-stage model for identifying an affected community which places those most affected at the centre of the definition. The second stage is to identify the relationships those most affected have with the wider elements of the sense of community to discover the existing community or communities which are affected. Illustrated by the siting of a low-level radioactive waste disposal facility at Dounrey in the north of Scotland, we show that elements of the lived community experience may have very different shapes, extents and conflicting interests which pose challenges for their incorporation into a siting process. The two-stage model presented in this paper, by placing those most directly affected at the centre and working from there out into the existing communities, identifies issues early in any siting process to improve their incorporation and amelioration. 相似文献
