An AHP-based water-conservation and waste-reduction indicator system for cleaner production of textile-printing industry in China and technique integration

The textile-printing industry in China makes an important contribution to the national economy. However, the associated pollution problems have caused gradual deterioration to the environment and adverse impacts on the local community. The indicator system of cleaner production gives a powerful tool to measure the level of cleaner production of textile-printing enterprises. In China, it has been a big problem of the textile-printing enterprise that consuming large amounts of fresh water and discharging large number of pollutants, and it is lacking in a scientific water-conservation and waste-reduction cleaner production evaluation system. To solve such problems, the establishment of water-conservation and waste-reduction cleaner production indicator system in textile-printing industry is proposed and assessed by the means of analytic hierarchy process (AHP) in this article. The judgement matrix is then determined with the Delphi Method combined. Finally, with the Yaahp software, the weight of each indicator is obtained. As an effective way to save water resource and reduce waste emission, the cleaner production technique integration is provided for the enterprises to solve the above problems and achieve the goals of saving water and decreasing the amount of disposed pollutants.     

Application of gray correlation analysis for cleaner production

The current methods used to select the schemes for cleaner production in China have some disadvantages. This paper presents research on gray correlation analysis with application to one cement factory in Chongqing, China. The results show that the gray correlation analysis can effectively avoid the subjective bias on the scheme selection for cleaner production. Schemes for cleaner production selected by the gray correlation analysis have better performance than those selected by the traditional method based on economic, environmental and technical indices.     

Barriers towards cleaner production for optimizing energy use and pollution control for foundry sector in Howrah,India

The most pressing environmental problems of casting production in small-scale foundry sector are gaseous emission and utilization of energy. Promotion of clean technology towards cleaner production has achieved significant improvement. But that technology was not widely accepted due to different barriers. However, incremental innovation with the existing technology got preference. For realization of the scenario, operational performances of cupola and pollution control system were evaluated in 12 units and 15 units, respectively. The study revealed that foundry sector, as a whole, could not ensure proper utilization of the energy and the control of emission. The parameters governing the efficiency of these technologies varied remarkably, which questions its consistency and reliability. This study focused the major barriers towards cleaner production with an aim to define the strategies to overcome the eco-friendly casting production.

Evaluation of cleaner production audit in pharmaceutical production industry: case study of the pharmaceutical plant in Dalian,P. R. China

The pharmaceutical industry in China makes an important contribution to the national economy. However, the associated pollution problems cause gradual deterioration of the environment and impact adversely on the local community. Cleaner production (CP) technology, an effective way to reduce waste emission and save resources, has been widely employed in the pharmaceutical industry in the developed countries. Such technologies have been applied in a number of factories in China, although there is no integrated assessment and implementation procedure for implementing CP technologies in pharmaceutical plants. To solve such problems, a series of CP options are proposed and assessed here. CP is a powerful tool for decreasing waste production, limiting environmental pollution and natural resource depletion. Moreover, the return on investment in CP is quick, so it would seem that CP activities should be very much in demand by enterprises. Reality is less optimistic: frequently only limited interest is expressed, even after an explanation; business people hesitate to become actively involved. The processes in the pharmaceutical production industry produce a vast amount of waste, including wastewater with high concentrations of organic substances (the principal component), solid waste, and organic off-gas. To solve such problems, a series of CP options are proposed and assessed in this study. Having consideration to environmental impacts and economic efficiency, four groups of medium/high cost CP options were screened in an integrated assessment. To verify the proposed options, a case study was conducted in Degussa Luyuan, Northeast China. The characteristics of resource consumption and waste emission during the production process were identified. The proposed options were evaluated according to different aspects. An integrated CP system based on the proposed options was designed and then implemented in the factory. In three years of practical use, the productivity and quality of alcohol product were improved, with a reduction in waste and pollution and a marked increase in water/energy savings. This study provides theoretical and practical support for the extensive application of CP technologies and sustainable development in China’s pharmaceutical industry. These methods include ways to clean up production that are incorporated in the process design, reforming present production technologies, updating the equipment, exploiting new producing flowcharts, using cleaner energy, building recycling into the manufacturing process, recycling waste, enhancing management, developing environmental protection technology, and ensuring satisfactory end-of-pipe disposal.     

浅析电镀行业的清洁生产措施

NewIndustrial Revolution and Environmental Protection

Serious environmental problems have appeared in China since the rapid economic growth 30 years ago, which affect human's health and become a limiting factor for further development. It has brought about the rethinking of traditional ways for economy development and environmental protection, and realized that the change in the model of development and environment protection is of significance. A new industrial revolution is needed for protecting the environment and promoting sustainable development. This paper discusses the characteristics of the new industrial revolution for sustainable development including cleaner production, circular economy, and industrial ecology. Lessons from China and abroad will be introduced to prove that new strategies for environment protection and economic development are needed.     

Financing resource efficiency and cleaner production in Central America

Resource efficiency, including cleaner production and energy efficiency (CP/EE), is an important strategy for developing countries to grow their economies in a sustainable manner. However, informational, technical and economic barriers often limit the implementation of such strategies in the private sector, particularly among smaller enterprises. Since the 1990s, international aid agencies, governments, banks and non-governmental organizations have supplied financial incentives to encourage enterprises to adopt resource efficient practices in Latin America. “Pathways to Cleaner Production in the Americas” (PCPA) was a 3-year multinational project focused on promoting cleaner production practices in micro, small and medium size enterprises (MSMEs) through collaboration with academia. In this paper, we examine the availability and utilization of different types of financing instruments for CP/EE in MSMEs in Central America. We survey nineteen programs across five countries to examine how effectively these instruments are utilized, barriers that hinder their adoption, and best practices for increasing their uptake. We also incorporate the experience of 39 MSMEs that participated in PCPA, with respect to their demand for CP/EE and external financing options. We find a mismatch between MSMEs’ demands and expectations with the supply and interest of financing programs, leading to the underutilization of the funds.
