清洁生产审核是实施清洁生产最有效的,也是最具可操作性的方法。在清洁生产审核预评估和评估阶段提出可行的无/低费方案,并按照"边审核边实施"的原则对所提的无/低费方案加以实施,能够使企业在短时间内达到"节能、降耗、减污、增效"的目的。以某化肥企业为例,找出企业存在的问题,评估企业的产排污情况,有针对性地提出了无/低费方案,并得以实施,为企业创造了一定的经济效益和环境效益。 相似文献

Because of its large population and rapidly growing economy, China is confronting a serious energy shortage and daunting environmental
problems. An increased use of fuels derived from biomass could relieve some demand for nonrenewable sources of energy while
providing environmental benefits in terms of cleaner air and reduced emissions of greenhouse gases. In 2003, China generated
about 25.9 × 108 metric tons of industrial waste (liquid + solid), 14.7 × 108 metric tons/year (t/y) of manure (livestock + human), 7.1 × 108 t/y of crop residues and food-processing byproducts, 2 × 108 t/y of fuelwood and wood manufacturing residues, and 1.5 × 108 t/y of municipal waste. Biofuels derived from these materials could potentially displace the use of about 4.12 × 108 t/y of coal and 3.75 × 106 t/y of petroleum. An increased bioenergy use of this magnitude would help to reduce the emissions of key air pollutants:
SO2 by 11.6 × 106 t/y, NOX by 1.48 × 106 t/y, CO2 by 1.07 × 109 t/y, and CH4 by 50 × 106 t/y. The reduced SO2 emissions would be equivalent to 54% of the national emissions in 2003, whereas those for CO2 are 30%. It is important to recognize, however, that large increases in the use of biomass fuels also could result in socioeconomic
and environmental problems such as less production of food and damage caused to natural habitats. 相似文献

Indicators for sustainable energy development in Mexico 总被引:1,自引:0,他引:1

This article presents a summary of a study on the application to the Mexican energy sector of a core set of indicators for sustainable energy development (ISED), developed by the International Atomic Energy Agency (IAEA). The study focused on the elaboration of socio‐economic and environmental indicators related to energy production and use, and was aimed at assessing Mexico's existing energy policies and identifying strategies and possible policies that could bring about improvements in major priority areas: energy intensity, atmospheric emissions, energy import dependency and use of renewables. While positive trends have been observed in relation to energy intensity and atmospheric emissions, Mexico is becoming more dependent on imports of gasoline, natural gas and other high‐value secondary energy sources, while exporting significant amounts of primary fuels, such as crude oil. Also, no significant increase has been observed in the use of renewable sources of energy. Social, economic and environmental policies need to be formulated for the energy sector and related investments (public and private) reinforced so that all economic sectors have access to energy from cleaner and more diverse sources. 相似文献
