Developing Clean Biomass Energy Using Briquettes Machines

Visualize about the food and other requirements of crore of people being well met. It is cleaned and processed cereals and pulses, coffee and coir, groundnut and oil, etc. that are made available in the market. What about the residues? These residues such as rice husk, jute sticks, bagasse, groundnut shells, coffee husk, mustard stalks are produced in huge quantities. They only pollute the environment.

Thanks to the emergence of briquette press manufacturers, who have revolutionized conversion efficiency of agro residues, facilitating the development of biomass energy resources. No more widespread air pollution or low thermal efficiency when loose biomass is directly burnt! No disposal of carbonaceous ash or sawdust!

The growing importance of the use of briquettes in homes and for industrial uses and the easy availability of technology solutions for conversion have only mitigated the various pollution problems related with agro residues. Awareness needs to be spread on a large scale so that biomass energy is properly exploited, thus saving the environment and saving the earth's natural resources for future generations.

Technological solutions for converting agro residues into biomass energy are generally available in two types - screw press and reciprocating ram/piston press. Briquetting plant of both types is used worldwide. Extensive exploitation of available technological solutions locally is still an issue and is yet to get a robust foothold, though the energy sources produced act as alternate fuel for wood, coal and lignite. But technical constraints are no longer a problem, as innovators and developers are manufacturing solutions to suit local conditions. It is lack of knowledge to adapt to the technology that is the constraint.

Where use of renewable source of energy is advocated on a large scale to conserve the earth's natural resources including forestry, the government should spread awareness about the importance of the production and use of biomass energy. Easy availability of raw materials for producing biomass energy in almost every village is an advantage in India.
Biomass densification is no new phenomenon. Use of briquettes machines, though limited, has been popular since the 1950s in several countries. This industry is still at its nascent stage in India. The Indian Renewable Energy Development Agency (IREDA), a finance granting agency, has financed many a projects with a view to improve this segment.

It is the piston press type of technology that is exploited more in India. IREDA regularly holds seminars to educate entrepreneurs, especially manufacturers about the attributes of biomass energy, technological innovations, etc. directed towards reviving this industry in India. Recent developments in technology have indeed initiated the interest factor in the Indian manufacturing community and end users alike.
