Role of Technology in Pollution Control
Some technologies are important for helping other technologies reduce pollution. For example, process controls such as meters and sensors can make many production processes more efficient and less polluting by providing improved control, which reduces waste and defects. Centrifuges can reduce the amount of solids in wastewaters, thereby reducing water pollution. Catalytic converters on engine exhaust systems can reduce air pollution. There are many such examples of technologies that help other technologies be cleaner. This is important in situations where there is a large investment in an existing technology already installed that cannot be easily or economically replaced with new and cleaner technology.
Remote Sensing Technology Analyzes Pollution - Softpedia
Life cycle analysis (LCA) is needed to determine if a particular technology really pollutes less than its alternatives. LCA is the examination of the environmental impacts of a product, from its origins as raw material through processing and production to use and final disposal. This can be a complex process. For example, fluorescent light bulbs may seem to be less polluting than incandescent light bulbs because they use much less energy. However, they actually use polluting chemicals such as mercury that are not found in incandescent light bulbs. So they use less energy, but more toxic chemicals. The choice of indicators for P2 performance and LCA, such as toxicity or energy efficiency, is important for evaluation.
