Most of the chemical manufacturing industries use electricity generated from coal for heating purposes. Use of coal generates oxides of carbon, nitrogen and sulphur which are responsible for Environmental Pollution. In view of this, attempts have been made to use alternate energy processes. This book deals with the use of microwaves, sonication and photo activation as alternate energy sources. Besides these energy processes, some reactions can also be carried out by just mixing of the reactants in a pestle-mortar or by just heating at low temperatures (40 - 70 C). These alternate energy processes will go a long way in minimizing the pollution of the environment.
