An introductory note on the environmental economics of the circular economy

This paper provides an introduction to some of the fundamental principles and approaches in environmental economics which are of significance to achieving an integrated sustainability science. The concept of a circular economy, introduced by the late David Pearce in 1990, addresses the interlinkages of the four economic functions of the environment. The environment not only provides amenity values, in addition to being a resource base and a sink for economic activities, it is also a fundamental life-support system. Environmental economists have suggested that, taking these four functions as an analytical starting point, unpriced or underpriced services should be internalised in the economy. In Europe significant advances have been achieved in the pricing of externalities by means of truly interdisciplinary analysis which accounts in detail for the environmental consequences. The monetary estimates reached as a result of such interdisciplinary research are gradually being applied to the economic analysis of environmental policy priorities. Although such figures provide only a partial and incomplete picture of the environmental costs at stake, they support and inform the analysis of the virtues of a circular economy for individual resources as well as for sustainability as a future trajectory.     

城市中水回用环境经济效益分析——以福州市洋里污水处理厂出水回用为例

以福州市洋里污水厂出水回用为例,运用费用效益分析方法计算得出静态投资回收期为2.64 a,远远小于基准投资回收期15~20 a。效益-费用比为1.44,大于1。结果表明,洋里污水厂达标出水作为中水回用的经济效益良好,并且具有明显的社会效益和环境效益。     

中水回用工程投建与运行实践

沈阳理工大学学生城中水设施的建设，不仅提高了水资源的重复利用率，创造良好的环境效益和经济效益，同时也为中水回用工作的推广实施积累了经验。尤其是采用比较简单的污水处理工艺达到中水回用的标准，其中最主要的部分是沉淀和生物接触氧化以及最后的过滤和消毒，这样的工艺比较适合中等规模的投资，从回用水的经济效益上看这样的中水回用系统还是比较适合推广。     

循环经济与上海可持续发展

建立能够体现化工行业特点的行业排放标准初探

化工行业具有传统的工业类型和新兴产业交叉渗透的特点。现有的污染物排放标准因涵盖行业过多、细化内容不够、可操作性不强、行业特点不突出,故不太适应化工行业的发展,建立新的化工行业污染物排放标准势在必行。文章概要介绍了我国现有污染物排放标准,分析了美国、欧盟、日本、德国等一些国家和组织的排放标准,提议建立能够体现化工行业特点的行业排放标准,以达到淘汰落后工艺和促进清洁工艺的目的。     

青岛市建设循环型经济社会的探讨

川西北哲波山微细浸染型金矿床岩浆岩特征

对川西北哲波山金矿区内出露的中 -酸性岩脉、岩株的类型、化学成分、地质特征以及微量元素、同位素、稀土元素等特征进行了研究 ,指出印支晚期和燕山早期的岩浆岩均属钙碱质岩系列 ,均起源于幔壳混源区 ,原始岩浆在成分上和演化上又存在着一定的差异性。岩浆岩为成矿提供了一定的物质基础。     

沉淀—树脂吸附法处理对氨基偶氮苯盐酸盐生产废水的研究

对氨基偶氮苯盐酸盐（ＰＡＢＳ）是生产染料的重要中间体。在ＰＡＢＳ生产过程中，排放出高浓度（ＣＯＤ４万～８万ｍｇ／Ｌ）、高色度（４万～８万）、高毒性（含苯胺和对氨基偶氮苯）和高氯（Ｃｌ－４万～１０万ｍｇ／Ｌ）的废水。利用中和沉淀—大孔吸附树脂吸附法进行了处理工艺的小试研究。结果表明，废水色度去除率达到９９９％，降到２０以下；出水中基本不含对氨基偶氮苯（ＰＡＢ）；出水中苯胺的浓度降到３ｍｇ／Ｌ。ＧＣ／ＭＳ分析的结果表明，乙醇脱附液中苯胺是最主要的有机物，所以利用该工艺能实现苯胺的回收。     

Landfill reduction experience in The Netherlands

Modern waste legislation aims at resource efficiency and landfill reduction. This paper analyses more than 20 years of landfill reduction in the Netherlands. The combination of landfill regulations, landfill tax and landfill bans resulted in the desired landfill reduction, but also had negative effects. A fierce competition developed over the remaining waste to be landfilled. In 2013 the Dutch landfill industry generated €40 million of annual revenue, had €58 million annual costs and therefore incurred an annual loss of €18 million. It is not an attractive option to prematurely end business. There is a risk that Dutch landfill operators will not be able to fulfil the financial obligations for closure and aftercare. Contrary to the polluter pays principle the burden may end up with society. EU regulations prohibiting export of waste for disposal are in place. Strong differentials in landfill tax rate between nations have nevertheless resulted in transboundary shipment of waste and in non-compliance with the self-sufficiency and proximity principles. During the transformation from a disposal society to a recycling society, it is important to carefully plan required capacity and to guide the reorganisation of the landfill sector. At some point, it is no longer profitable to provide landfill services. It may be necessary for public organisations or the state to take responsibility for the continued operation of a ‘safety net’ in waste management. Regulations have created a financial incentive to pass on the burden of monitoring and controlling the impact of waste to future generations. To prevent this, it is necessary to revise regulations on aftercare and create incentives to actively stabilise landfills.
