It has been rightly said that waste not, want not. This is because waste can prove to be potential resource because they can be recycled and used as sustainable fuel.
The global economy is dominated by technologies that rely on fossil fuel like petroleum, coal, natural gases to produce power, fuel, materials and chemicals. Even the use of conventional fuel like oil coal and electricity has increased in the last 25 years in Asian countries.
India still imports crude oil and petroleum that comes to over 111.92 million tonnes per year. This leads to heavy dependence on imported oil and leads to a number of social and economic uncertainties. Presently there is a worldwide interest to conserve biomass that leads to development of renewable source of energy for both economic and environmental set-ups.
Biomass: Means for Employment Generation
Biomass is a domestic energy resource that is available abundantly and presents as promising renewable source of fuel. It can prove to be an alternative for various fossil fuel resources. Biomass is the third largest primary source of energy in the world after oil and coal.
This alternative source of energy still meets the fuel requirement in rural areas in most developing nations. According to briquette machine suppliers in India the agricultural residues comprise of one of the important sources of biomass fuel which are divided into two groups that are crop residues and agro-industrial residues.
Major Sources of Agro Wastes
Some of the major crop residues in India are oil seed crops, maize stalks and cobs, cotton and mustard stalks, pulses, sorghum, wheat, miller, paddy and branches of varied shapes, densities and form. The agro-industrial residues are groundnut shell, cotton wastes, coir pith, coconut shell, mustard husk, tamarind shell, cassava peel etc.
Over the past few years the government is looking forward to aid its expertise in agro waste briquetting technology. This can prove to be one of the economic solutions for supplementing all fuel requirements and socio-economic developments in rural areas. It can also prove to be source of income generation for rural population.
Biomass Briquettes: The Green Charcoal
Biomass briquettes are also known as ‘green charcoal’ or simply organic briquettes derived from organic waste. They are manufactured using briquette press machines for small business and domestic institution. This creates a number of job opportunities and leads to less destruction of woods.
Broadly speaking there are two types of briquettes which are carbonised and non-carbonised. Briquettes can be made of various shapes and sizes depending on whether they can be used in household, industry level or institution. They are primarily made of three ingredients, which are: binder, char from waste and filler mixed in right proportion.
The briquettes are manufactured using machines in which the mixture is loaded directly into the briquetting mould to form uniform sized cylindrical briquettes. It can be used an alternative source of fuel for cooking, in tea shops, tandoor chulhas, small hotels and laundering. To sum it, briquetting can prove to be an excellent source for rural India.
