Collectively, small hotels constitute a significant solid waste management (SWM) problem. Little research has focused on the SWM practices of small hotels. In the United Kingdom, much of the solid waste generated by small hotels goes to landfill. This study uses a constructionist approach to investigate SWM issues in small hotels in a local authority in Wales and examines the role of the public sector in helping small hotels manage their solid waste effectively. The results revealed that only a minority of small hotels were considering the adoption of sustainable SWM practices, either because hoteliers felt negatively about sustainable SWM alternatives or perceived challenges – an issue which necessitates government intervention. At the time of this study, the public sector provided only very modest services to enhance SWM practices. This study proposes a best practice model for the public sector to encourage small hotels to manage their solid waste effectively, in order to reduce or even eliminate waste for landfill. Local authorities' support is required to make waste management hierarchy options more accessible to small hotels and should incentivise better waste management through increasing the gap between the costs of landfill and recycling waste. 相似文献

铬渣产量大、毒性剧烈,是严重污染环境和危害人类健康的危险废物。铬渣的环境污染问题已经引起了国家的高度重视,要求2010年底前,所有历史堆存铬渣实现无害化处理。铬渣堆放所产生的含铬渗滤液已对周围的土壤、地下水乃至居民身体健康造成危害。因此,在铬渣得到治理的同时,含铬渗滤液必须得到有效治理。系统评述了铬渣渗滤液的各种治理技术和应用现状,并展望了含铬废水处理技术的发展前景。 相似文献

昆明市采用原生垃圾卫生填埋的单一方式处理垃圾,资源化程度低,同时对环境造成了严重的二次污染.昆明市生活垃圾处理应该采用基于垃圾分类(分选)的综合处理技术,即对于易降解的有机生活垃圾采用厌氧消化的处理方式,可以得到绿色能源和肥料;不易降解的部分进行回收或生产废弃物复合材料.卫生填埋只能作为垃圾产业化处理的最终处置方式. 相似文献

The UK will introduce in 2004 a system of tradable permits for the landfill of municipal waste, in response to an EU directive setting limits on such activity. Tradable permits are becoming an increasingly popular method of dealing with some environmental issues — for example, sulphur dioxide (SO2) emissions in the USA. This paper describes the background to the landfill proposals and provides an analysis of how the permit system might work. Estimates are made of the possible savings in compliance costs of a permit system compared with a conventional ‘command–and–control’ approach. These estimates are subject to a considerable degree of uncertainty, related to factors discussed in the paper. 相似文献

以某地生活垃圾填埋场渗滤液处理工程升级改造为例,介绍了一种有效的渗滤液处理工艺.实践证明,采用“均质—MBR超滤—纳滤”工艺,并预留反渗透等深度处理工艺接口,是生活垃圾填埋场渗滤液处理工程升级改造的可行途径. 相似文献
