Municipal solid waste has become one of the largest contributors of pollution globally, and especially in developing economies like India. Landfills have marred our city- scapes and polluted our air and water.
Landfills are no more a solution!
Not only in times of increasing urbanisation and population or of the growing industrialisation of countries does waste treatment become more and more demanding. Each year thousands of acres of land are lost to landfills. The methane produced from decomposing waste is a potent greenhouse gas. And the costs associated with using a landfill are rising as cities and countries truck their waste ever farther away.
Reasons like these, and others, are causing municipalities to re-evaluate the benefits of waste to energy facilities.
Additionally, more and more governments establish subsidiaries for an ecological and friendly waste treatment.
Waste to Energy is often viewed as primarily a waste management solution rather than a valuable energy resource. Consequently, its full potential has not been realised.
An efficient and reliable technology is the key to harnessing energy from waste and provides many benefits.
Computerised controlling of key parameters is most important in the reaction process to maximise the performance of the plant. Except for providing the feed at the pre-digester, all process is human independent. The following parameters are monitored constantly with necessary corrective measures for each of them, if required.
Below is a typical flow diagram of a Biogas Plant:
