Beehive briquetting technology

Your Rating:

This technique is an adaptation of methods used to produce charcoal for fuel. Unwanted biomass and industrial waste (e.g., saw dust, rice husk, and waste paper), used for making different kinds of bio-briquette. In this case from the forest weed ‘banmara’ (Eupatorium adenophorum), is converted into charcoal in a charring drum and then turned into solid fuel bio-briquettes. The charcoal powder is mixed with bentonite clay at a ratio of 3:I, pressed into honeycomb-shaped moulds, and sun-dried. The biobriquettes can be used for cooking or heating. They can be ignited easily from below using waste paper or dried leaves and twigs. Once the lower portion catches fire, the flames start coming up through the nineteen holes in the briquette; the airflow ensures smokeless burning – a pollution free and environmentally friendly source of energy. Biobriquettes can also be make from industrial waste such as saw-dust and waste papers. 

Biomass briquettes are made from agricultural waste and are a replacement for
fossil fuels
 
such as oil or coal, and can be used to heat boilers in manufacturing plants, and also have applications in
 
developing countries
.
 
Biomass briquettes
 
are a renewable source of energy and avoid adding fossil carbon to the atmosphere.

A number of companies in India have switched from furnace oil to
 
biomass briquettes
 
to save costs on boiler fuels. The use of biomass briquettes is predominant in the southern parts of India, where coal and furnace oil are being replaced by biomass briquettes. A number of units in
 
Maharashtra
 
(India) are also using biomass briquettes as boiler fuel. Use of biomass briquettes can earn Carbon Credits for reducing emissions in the atmosphere. Lanxess India and a few other large companies are supposedly using biomass briquettes for earning Carbon Credits by switching their boiler fuel. Biomass briquettes also provide more calorific value/kg and save around 30-40 percent of boiler fuel costs.

A popular biomass briquette emerging in developed countries takes a waste produce such as sawdust, compresses it and then extrudes it to make a reconsistuted log that can replace firewood. It is a similar process to forming a wood pellet but on a larger scale. There are no binders involved in this process. The natural
 
lignin
 
in the wood binds the particles of wood together to form a solid. Burning a wood briquette is far more efficient than burning firewood. Moisture content of a briquette can be as low as 4%, whereas green firewood may be as high as 65%.


Achievement

Near the vicinity of the community forest area, there is a possibility of much more biomass as a raw materials of this activities. So, most of the biobriquette factory is situated at the periphery of the community forest area. The local people can get the opportunity to work in these factories in the leisure time from their farm activities. The major workers are mostly the female villagers. Workers are easily available in the near vicinity villages with cheap remuneration (Rs 3/- per piece). Those factories are situated at the roadhead. So, the market is easily accessible with the appropriate price. The demand of this briquette is gradually increasing in the urban and the vicinity town areas with the fast growing populations.
