Local Area Quotas for Industrial Emissions along Reaches of the Pearl River in Guangdong

There is an obvious departure from the regional equilibrium of developments between the upper and lower reaches of the Pearl River in Guangdong, which resulted in ＂the effects of contra-geography-grads development＂. It is mainly because the upriver mountainous areas have been deeply stuck in industrialization delay and marginalization plights, so that nearly 40 million local people have conceived a dream to get rid of ＂the vicious circle of poverty＂ by speeding up industrial development. But the problem is that such industrialization efforts on a large scale in mountainous areas are encountering the bottleneck of environmental capacity that strictly limits industrial emissions along the upper reaches of any water system. As a solution, an institutional arrangement called ＂the Local Area Quotas for Industrial Emissions along the Pearl River＂ is put forward supposed to give corresponding compensation to the rights of industrial development yielded by some areas with lower environmental capacity through the distribution and trading of IDQs.     

谁污染,谁付费--关于广东省垃圾处理费征收的思考

2002年1月1日,《广东省城市垃圾管理条例》(简称《条例》)颁布实施,这是全国规范城市垃圾管理的第个地方性法规。《条例》第24条规定:“从事城市垃圾经营服务的单位接受委托清扫、收集、运输、处理垃圾,实行有偿服务。有偿服务的具体办法由省人民政府另行制定。”至此,一段时间来引人关注的城市垃圾处理费的征收方案在广东仍暂不得实施。

一种回收废聚苯乙烯（PS）泡沫塑料方法：蒸汽熔融挤压法的工艺分析

本文介绍了一种可在生产厂内回收废聚苯乙烯(PS)泡沫塑料的简单方法。该法将粉碎后的PS泡沫塑料颗粒装填在成型模具内,经蒸汽加热表面熔融后,外力挤压冷却成型。从而在基本不改变废物原料外型的情况下对其进行低能耗回收,获得性能与原产品较为接近的回收产品。文中对该法的原理、设备、操作工序及工艺条件等作了介绍和分析。
