Recycling of waste is an
important component here. We can make use of this in paper industry and
aluminium can manufacturing industry where used product has an intrinsic value.
In Japan, more than half of its waste materials are recycled. Modernization of
technology can also be used for energy conservation. Developed countries are
using modern technologies and are able to reduce the energy consumption during
production. Waste heat utilization is a significant way of energy conservation,
especially in glass industry. Flue gases produced from the furnace of a glass industry
can be used for the generation of electric power by proper mechanism. The
exhaust from backpressure turbine during electric power generation can be used
for crop drying and similar applications. If there is any condensed water
vapors, we can use it for heating fish farm, poultry farm, pig farm etc.
Optimum use of proper types of energy and fuel can save energy considerably.
Cogeneration where electricity and heat are generated in a single installation
is an excellent tool for energy conservation. Manpower skill is an important
component in energy conservation. Proper training has to be given to improve
their skill and attitude. Proper training helps them to carry out proper
operation and maintenance.
