The main research question of our study was as follows: What opportunities for upgrading material efficiency and waste minimisation can be found in small and medium-sized enterprises (SMEs)? The empirical material consisted of 41 theme interviews in Finnish industrial SMEs. In the article, the SMEs are assigned to four different categories according to their attitudes towards environmental protection. This analysis also explains why SMEs build up environmental management systems (EMSs). The EMSs do not appear to provide much impetus for SMEs to implement waste minimisation. The reduction of wastes in SMEs is driven more by the costs of raw materials than by waste costs. From the standpoint of environmental authorities, it is therefore crucial to find procedures to support SMEs in increasing their efficient use of materials. 相似文献

Hedonic research indicates that residential property values are reduced by increased proximity to hazardous waste sites, a measure of diminished environmental quality. Standard hedonic procedures measure proximity by the linear distance between a property and a waste site of interest. A sample of properties is then used to estimate a distance-to-site coefficient that measures the effect of the hazardous waste site on surrounding property values. These estimates can help policy makers assess the external effects of hazardous waste sites and may also be useful in both prioritizing and assessing the benefits of cleanup. In an urban situation, hazardous waste sites are often located near other industrial disamenities such as railroads, storage tanks, industrial noises, and air pollution. This spatial grouping of hazards may be due to economic forces or due to policy instruments such as zoning. As a result, distance to hazardous waste site may be correlated with distances to other industrial disamenities. Standard hedonic procedures that use a distance-to-site variable may suffer from omitted variable bias when the bundled industrial disamenities are present but ignored. Our empirical analysis examines this bias by assessing hedonic regressions with and without a measure that accounts for industrial activity. 相似文献

Just as the application of technology in mining processes can cause pollution, it can also be harnessed to minimise, and sometimes eliminate, mine-related contaminants. Waste minimisation can be achieved through decreased waste production, waste collection, waste recycling, and the neutralisation of pollutants into detoxified forms. This article reviews examples of how technology can be used to minimise air, water, land and noise pollution in the mining industry. 相似文献

Life cycle assessment is emerging as a powerful tool in the evaluation of the environmental impact of manufacturing processes. This paper describes a general methodology for the life cycle analysis of manufacturing processes taking into account the flexibility and decision-making potential of knowledge base systems. Emphasis is placed on on-site waste minimisation and associated sustainability characteristics in relation to environmental impact assessment and process improvement. The ensuing software model is applied with some success to an initial study of pulp and paper manufacture. 相似文献

Human gene therapy is currently seeing an increase in the use of plasmid (pDNA)-based vectors as a preferred choice of vehicle for delivery of the therapeutic gene into the body. In this regard, the environmental impacts of the waste streams from the possible industrial scale manufacture of pDNA require more detailed assessment. In this study, an initial assessment was made of the nutrient phosphorus (P) inputs to four fermentation processes recommended for the industrial scale production of pDNA for the purposes of gene therapy. Phosphorus inputs to each of the four selected fermentation processes ranged from approximately 60 mg l?1 up to 3000 mg l?1 in the fresh media. However, the spent media waste from each of the processes exhibited only a minor reduction in the phosphorus concentrations indicating minimal uptake of P by the microorganisms. This unutilised excess level of phosphorus nutrient within the waste streams poses a strong potential for environmental impact. Waste minimisation studies were undertaken on one model fermentation process with the aim of reducing unnecessary phosphorus input. An optimised media containing a 98% reduction in added P to the media was developed. This phosphorus-minimised media had little quantitative effect upon cell biomass produced and no effect upon the quantity or quality of pDNA produced, relative to the control media. The reduction in P requirement results in an overall cost savings of 12% per fermentation batch, would simplify subsequent wastewater treatment and would contribute to slowing the depletion rate of a valuable, finite natural resource. 相似文献
