为了给危险废物处理处置企业开展清洁生产提供一些基础性引导,先对比分析了危险废物处理处置企业和常规企业开展清洁生产的异同,然后以采用水泥回转窑协同处置危险废物的R公司为例,从8个方面进行产排污和清洁生产潜力分析,并结合危险废物处理全过程开展物料平衡分析,提出可行的无/低费方案和中/高费方案共19项。研究结果表明,危险废物处理处置企业存在可观的清洁生产和节能减排潜力,通过开展清洁生产可有效从源头防治二次污染,实现节能减排。     

火电行业清洁生产与末端治理技术对二氧化硫减排效果评估

为探明清洁生产技术在我国大气污染物削减中所起的作用,本文以火电行业为例,以SO_2作为特征污染物,对“清洁生产”和“末端治理”技术进行了筛选,建立了削污和减排效果分析模型,并收集火电行业的权威统计数据,计算了火电行业“清洁生产”技术削污量与“末端治理”技术减排量及两类技术各自削减量占比情况,研究了建国以来(1949—2013年)我国火电行业清洁生产技术削污效果和末端治理技术减排效果及其演变规律,并在此基础上提出政策建议.研究结果显示,以火电行业发电效率最低的低温低压发电技术为基准线,1949—2013年65年期间电力行业通过清洁生产技术累计实现SO_2削污量为4.94亿t,节约4940亿元的环保资金投入,削污率达到58.5%;2002—2013年12年期间电力行业末端治理技术累计实现SO_2减排量为1.10亿t,减排率为13.0%.

The Application of Chemical Leasing Business Models in Mexico

- DOI: http://dx.doi.org/10.1065/espr2006.02.294 Background, Aim and Scope. To better address the requirements of the changing multilateral order, the United Nations Industrial Development Organization (UNIDO) Cleaner Production Programme, in 2004, developed the new Sustainable Industrial Resource Management (SIRM) approach. This approach is in accordance with the principles decided at the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil in 1992. Unlike the traditional approaches to environmental management, the SIRM concept captures the idea of achieving sustainable industrial development through the implementation of circular material and energy flows in the entire production chain and reduction of the amount of material and energy used with greater efficiency solutions. The SIRM approach seeks to develop new models to encourage a shift from selling products to supplying services, modifying, in this manner, the supplier/user relationship and resulting in a win-win situation for the economy and the environment. Chemical Leasing represents such a new service-oriented business model and is currently being promoted by UNIDO′s Cleaner Production Programme. Main Features. One of the potential approaches to address the problems related to ineffective use and over-consumption of chemicals is the development and implementation of Chemical Leasing business models. These provide concrete solutions to the effective management of chemicals and on the ways negative releases to the environment can be reduced. The Chemical Leasing approach is a strategy that addresses the obligations of the changing international chemicals policy by focusing on a more service-oriented strategy. Mexico is one of the countries that were selected for the implementation of UNIDO's demonstration project to promote Chemical Leasing models in the country. The target sector of this project is the chemical industry, which is expected to shift their traditional business concept towards a more service and value-added approach. This is being achieved through the development of company specific business models that implement the above-indicated Chemical Leasing concept with the support from the Mexican National Cleaner Production Centre (NCPC). Results and Conclusions. The implementation of Chemical Leasing in Mexico has proven to be an efficient instrument in enhancing sustainable chemical management and significantly reducing emissions in Mexico. Several companies from the chemical industrial sector implement or agreed to implement chemical leasing business models. Based on the positive findings of the project, several Mexican companies started to negotiate contents of possible Chemical Leasing contracts with suitable business partners. The project further aimed at disseminating information on Chemical Leasing. It successfully attracted globally operating companies in the chemicals sector to explore possibilities to implement Chemical Leasing business models in Mexico. At the international level, the results of the UNIDO project were presented on 20TH September 2005 during a side event of the Strategic Approach to International Chemicals Management (SAICM) Preparation Conference in Vienna. Recommendations and Outlook. To facilitate the promotion and application of Chemical Leasing project at international level, UNIDO is currently developing a number of tools to standardize Chemical Leasing projects. These include, among others, Chemical leasing contract models; Chemical Leasing data base to find partners for chemical leasing; and guidelines to implement Chemical Leasing projects and work programmes.
