Industrialization and urbanization result in significant changes in lifestyle. These lifestyle changes seem to lead to unsustainable
consumption patterns and increase the generation of various kinds of environmental loads, especially the amount of municipal
solid waste (MSW). Taiwan is a small island with scarce natural resources. The economic development in Taiwan has resulted
in the generation of large amounts of MSW. As a result, the Taiwan Environmental Pollution Administration (TEPA) has produced
regulations for waste minimization and has imposed several important policy measures that have successfully reduced the MSW
discard rate in recent years and have established a public recycling network as a part of the MSW collection. Nowadays, the
objective of the MSW policies in Taiwan is to develop a “zero-waste society.” This article aims to review the MSW management
progress in Taiwan and to project future MSW discards up to 2011 based on the national plan and assumed scenarios for socioeconomic
variables. According to the analysis results, a more sustainable consumption pattern can be proposed and the corresponding
MSW management system can be planned so as to develop a low-waste-discard society. 相似文献

Introduction
This article examines the extent to which investing in safety during the creation of a new chemical installation proves profitable.Method
The authors propose a management supporting cost-benefit model that identifies and evaluates investments in safety within a chemical company. This innovative model differentiates between serious accidents and less serious accidents, thus providing an authentic image of prevention-related costs and benefits. In classic cost-benefit analyses, which do not make such differentiations, only a rudimentary image of potential profitability resulting from investments in safety is obtained.Results
The resulting management conclusions that can be drawn from such classical analyses are of a very limited nature. The proposed model, however, is applied to a real case study and the proposed investments in safety at an appointed chemical installation are weighed against the estimated hypothetical benefits resulting from the preventive measures to be installed at the installation.Conclusion
In the case-study carried out in question, it would appear that the proposed prevention investments are justified.Impact on industry
Such an economic exercise may be very important to chemical corporations trying to (further) improve their safety investments. 相似文献993.

公路隧道发生火灾开启横通道后,形成通风网络。本文以重庆地区吕家梁隧道为工程依托,进行了斜井前后不同位置发生火灾的通风网络模拟。结果表明,斜井前发生火灾时,受斜井浮力效应、风流密度变化等的影响,主风机的工作压力降低,而体积流量增加;当火灾发生在斜井前隧道时,采用斜井单抽方式可实现全部火灾烟流从竖井中排除,斜井前设射流风机增压调节、斜井后设射流风机增阻调节是一较好方案;对于斜井后发生火灾,采用全射流火灾通风和斜井压入两种通风方案均能满足火灾风流控制要求,虽然后者需要开启轴流风机,通风能耗大,但火灾通风的时效性要好于前者。 相似文献

Based on the flood affected area (FA) data of the provinces in China from 1950 to 2005, the article discusses the change of the flood patterns in China, and investigates its relationship with climate change and human activities. The flood center shifted from North China and the Yangtze-Huaihe basin in the 1950s towards the south, north and west of China, and located in the south of the Yangtze River and South China after the 1990s. The FA in the western provinces was continuously on the rise since the 1950s. There are two characteristics for the future flood pattem in China. The pattern of "flood in the south and drought in the north" depends on the north-south shift of the maximum rainfall region in eastern China. The flood intensification to the west of Hu Huanyong's line mainly results from the increase of rainfall, extreme precipitation and the melting of glaciers under the background of human activity magnification. 相似文献
