F.O. Ongondo I.D. Williams J. Dietrich C. Carroll 《Waste management (New York, N.Y.)》2013,33(12):2600-2606
In Europe, socio-economic enterprises such as charities, voluntary organisations and not-for-profit companies are involved in the repair, refurbishment and reuse of various products. This paper characterises and analyses the operations of socio-economic enterprises that are involved in the reuse of Information and Communication Technology (ICT) equipment. Using findings from a survey, the paper specifically analyses the reuse activities of socio-economic enterprises in the UK from which Europe-wide conclusions are drawn. The amount of ICT products handled by the reuse organisations is quantified and potential barriers and opportunities to their operations are analysed. By-products from reuse activities are discussed and recommendations to improve reuse activities are provided. The most common ICT products dealt with by socio-economic enterprises are computers and related equipment. In the UK in 2010, an estimated 143,750 appliances were reused. However, due to limitations in data, it is difficult to compare this number to the amount of new appliances that entered the UK market or the amount of waste electrical and electronic equipment generated in the same period. Difficulties in marketing products and numerous legislative requirements are the most common barriers to reuse operations. Despite various constraints, it is clear that organisations involved in reuse of ICT could contribute significantly to resource efficiency and a circular economy. It is suggested that clustering of their operations into “reuse parks” would enhance both their profile and their products. Reuse parks would also improve consumer confidence in and subsequently sales of the products. Further, it is advocated that industrial networking opportunities for the exchange of by-products resulting from the organisations’ activities should be investigated. The findings make two significant contributions to the current literature. One, they provide a detailed insight into the reuse operations of socio-economic enterprises. Previously unavailable data has been presented and analysed. Secondly, new evidence about the by-products/materials resulting from socio-economic enterprises’ reuse activities has been obtained. These contributions add substantially to our understanding of the important role of reuse organisations. 相似文献

强化活性炭吸附技术深度处理焦化废水的可行性研究 总被引:3,自引:0,他引:3
采用混凝沉淀、活性炭吸附以及混凝沉淀 活性炭吸附工艺对焦化厂生化出水进行深度处理.单独混凝沉淀或活性炭吸附均可以将水样中COD降到100 mg/L以下,达到国家污水一级排放标准和冷却用水建议标准.活性炭根据不同的材质和进水而表现出不同的吸附性能,对于焦化厂生化出水,煤质炭Ⅰ和果壳炭均表现出良好的吸附效果,并使出水COD<100 mg/L,但处理成本较高.混凝沉淀 活性炭吸附工艺充分发挥适合去除大分子污染物的混凝沉淀与适宜去除小分子污染物的活性炭吸附技术两者的协同增效作用,吸附单元采用廉价的煤质炭,使出水水质达到个别生产或生活用水回用标准,并且降低深度处理成本.研究结果表明,混凝沉淀 活性炭吸附作为焦化厂生化出水回用工艺是经济可行的. 相似文献

Creta Farm Plc, owns the largest meat producing (pigs rearing), processing and packaging unit in the island of Crete, in Greece, placed outside the city of Rethymnon in the north coast of the island. From the farm, where more than 20 000 pigs of various ages and sizes live, 300–320 m3 of wastewater are collected in a daily basis. From the slaughterhouse and the processing unit another 100–125 m3/d are produced. The wastewater treatment system is a combination of settling and aeration tanks, with decanters operating in different phases of the process, mainly for the removal of the solids from the wastewater. The average biochemical oxygen demand and total suspend solids values of the treated effluent are 40 and 80 mg/l, respectively. From this almost secondary treated effluent about 100 m3 are used for cleaning the sewage pipes of the rearing unit (animals houses). The remaining 300 m3 are disinfected with a weak chlorine solution before used for irrigating trees, grass and various other plants. More than 2000 eucalyptus trees, 1500 tamarix trees and a large number of olive trees are growing in the site creating a pleasant view and at the same time help minimising the odour problem. 相似文献

我国是世界上13个贫水国之一,水资源紧缺的问题在一些地区已制约经济和社会的发展。中水主要是指城市污水或生活污水经处理后达到一定的水质标准,可在一定的范围内重复使用的非饮用杂用水。中水的水质介于上水和下水之间,是水资源有效利用的一种形式。开展中水回收工作,已经显现出开源和减轻水污染的双重功能。 相似文献

Based upon a survey on household electronic and electrical equipment, this paper provides information on the public's perception of the local environmental quality, environmental awareness and environmental performance, and of their willingness to pay for improving environmental quality and making green purchases. The results indicate that Ningbo residents are not satisfied with the local environmental quality, and they would like very much to share environmental responsibility. About 64% of the respondents are aware of Chinese environmental labeling. Nearly 70% and 80% of the respondents are willing to pay for environmental improvement and to purchase environmentally friendly products, respectively. The amount of household electrical and electronic equipment has increased dramatically and most of them are phased out within their product lifetimes. Of all the respondents, 61% chose to reuse and recycle waste electrical and electronic equipment. 相似文献
