Burn or bury? A social cost comparison of final waste disposal methods

This paper evaluates the two well-known final waste disposal methods, incineration and landfilling. In particular we compare the social cost of two best-available technologies using a point estimate based on private and environmental cost data for the Netherlands. Not only does our comparison allow for Waste-to-Energy incineration plants but for landfills as well. The data provide support for the widespread policy preference for incineration over landfilling only if the analysis is restricted to environmental costs alone and includes savings of both energy and material recovery. Gross private costs, however, are so much higher for incineration, that landfilling is the social cost minimizing option at the margin even in a densely populated country such as the Netherlands. Furthermore, we show that our result generalizes to other European countries and probably to the USA. Implications for waste policy are discussed as well. Proper treatment of and energy recovery from landfills seem to be the most important targets for waste policy. Finally, WTE plants are a very expensive way to save on climate change emissions.

Embedded industrial production systems: Lessons from waste management in zinc production

To meet the sustainability challenge private companies must implement corporate strategies and adopt novel technologies. The technical and social embeddedness of industrial production systems, however, complicates these systems' transition towards sustainability. In the paper, mechanisms and conditions are reported for the development and implementation of waste management options in embedded industrial production systems. The focus is on the Dutch zinc production industry, which had to deal with a major waste problem; the generation of jarosite. The industry's options were to increase the jarosite waste storage capacity, to develop a jarosite treatment process or to switch to a zinc-ore of low-iron content whereby no jarosite waste would be generated anymore. Required conditions appeared to be a combination of technological capability and technical embedding and favourable economics. Case study research, however, revealed that adequate stakeholder management is crucial to address social pressure exerted and to obtain external acceptance for any transition strategy. Whilst appropriate, internal technological capabilities are important, effective interactions with and enrolment of various firm-external actors are crucial. In the case of zinc, access to the heterogeneous external actor network was critical for the development of the jarosite treatment solution direction. In conclusion, both the technical, organizational and social embedding of new technologies are crucial for successful implementation.     

构建我国个人信用体系保障机制--韩国"坏银行"重整制度考察之思考

我国个人消费信贷近几年的发展十分迅速，但是在个人消费信贷的快速发展中，银行由于个人不良信贷所引发的不良债权比重逐年上升，而且信用环境不良有恶化这一问题的趋势。个人信用制度的建设、个人不良信贷资产的处置和我国个人信用安全体系的构建，已经成为摆在我们面前的现实问题。韩国资产管理公司在处置信用卡公司不良债权中的“坏银行”重整制度，构成了韩国金融安全网络的重要组成部分，这一制度设计值得我们借鉴。     

淮河流域污染治理需要企业实施绿色营销

作为我国重要的农产区和传统工业生产基地,淮河流域污染严重,治理污染刻不容缓。由于淮河最主要的污染源来自工业企业,本文着重从工业企业这一微观角度出发,引入绿色营销的概念,分析了企业加强环保意识的重要性,并通过对企业实施绿色营销的博弈分析,指出绿色营销是企业保证可持续发展的必然选择。     

油井采出液处理效果分析及改进措施研究

通过对油站和污水站的化学成分分析，找出了电脱水器跳闸的原因：由于污水中的一些成分导致腐蚀，腐蚀产生的硫化铁和铁颗粒，随着油水混合液在管线中运移，在电脱水器上越积越厚，致使电脱水器上导电率增高，电脱水器跳闸。提出了改善注入水水质，减缓腐蚀的有利措施。     

我国商业银行不良资产的现状与治理对策

不良资产问题是困扰全球银行业的一个难题。事实上，不良资产问题是商业银行经营发展中不可避免的时常要遇到的问题，许多国家为化解银行不良资产进行了长期、艰苦的探索。当前，我国的银行业同样面临着不良资产比例过高、处置艰难的障碍。由于不良资产问题事关金融体系的稳定，事关国家经济的发展和社会稳定，而且极大地制约了银行的信贷投放能力和积极性，因此，面对不良资产形成与处置中的困难与问题，从研究不良资产在制度、法律、社会信用及银行自身的组织及管理机制出发，探索符合我国国情的银行不良资产的化解途径和办法，具有十分重要的现实意义。     

Managing sustainable practices in cruise tourism: the assessment of carbon footprint and waste of water and beverage packaging

This paper's aim is to present an analysis of the carbon - dioxide emissions and waste associated with water and beverage packaging. The assessment of the packaging's carbon footprint (CF) and waste is also considered for all passengers who visit Italian ports on cruise ships. These factors are considered at two points in time (2010 and 2018) to allow for the evaluation of changes due to technological innovations in the packaging sector. Finally, a best-case framework scenario for the management of water and beverage packaging materials is identified to evaluate whether the use of appropriate strategies can reduce CF and waste in this sector. The results indicate that adequate changes in packaging can minimize waste and reduce the consumption of materials and energy resources in the packaging production cycle, thus creating environmental benefits.     

北京山区果园生态系统消解畜禽粪便的服务功能及其价值分析——以北京市平谷区果园为例

山区面积占北京市土地总面积的62%,主要担负着北京的生态屏障功能,而山区经济的发展是山区生态功能发挥的有力保障,果树产业的健康发展是协调二者关系的有效途径。因此,文章以北京市平谷区为例,在分析历年畜禽养殖量及粪便排泄量的基础上,针对果园生态系统的废物处理功能及其经济价值进行了估算,以期为果树产业的健康发展提供依据。结果表明,平谷区畜禽养殖规模发展较快,2006年畜禽粪便的排泄量已达133.86万t;而果园生态系统在对畜禽粪便的消纳方面发挥了较大的作用,果园生态系统消纳畜禽粪便的物质量已经由1997年的24.52万t增加到2006年的52.42万t,消纳量增加了98%,平均每公顷果园每年消纳畜禽粪便166t猪粪当量。消纳畜禽粪便的生态服务价值逐年递增,到2006年已达43 620.35万元(2008年现价),与1997年相比增加了21 549.81万元(2008年现价)。
