Air pollution can be reduced by using bag filters, electrostatic precipitators and cyclone separators that separate large and small particulate matter from emission gases. Sewage treatment plants can be used for the purification of wafer.
These technologies require large investments. However, a cost-benefit analysis of losses due to pollution and gains by using technology indicate that, purely in monetary terms, the gains double up for the money spent. Our country has meagre resources, so a more desirable strategy is the prevention of pollution by waste reduction. Studies have shown that in industrial sector waste reduction makes tremendous economic sense and helps in curbing pollution.
