Welcome to BG-RCNN
“Promoting the Bio-Briquette Sector in Nepal through Organizational Collaboration, Knowledge Transfer, & Information Dissemination”
The BG-RCNN is a loose network of national non-government organizations (NGO’s), national organizations, international organizations, government organizations, industry leaders and business, educational institutions, research institutions and any other groups that may have valuable expertise, information and product knowledge relevant to the bio-briquette sector. The purpose of the BG-RCNN is to form a network of appropriate organizations that will collaborate, transfer knowledge and disseminate relevant information to stakeholders to promote the awareness, use, feasibility, and functionality of bio-briquettes within Nepal.
History of Bio-Briquette in Nepal
Briquetting is the process of converting low bulk density biomass into high density and energy concentrated fuel briquettes. People have been using traditional animal dung briquettes for cooking inrural Nepal since time immemorial. These low-pressure traditional briquettes made from animal dungand biomass (rice straw, jute sticks, etc) are of different shapes, sizes and composition. The first biomass briquetting plant Nepal Bio-Extruder Industry in Nepal was established in 1982 in Thapathali Kathmanduwith the annual production capacity of 900 metric tons. It used the pyrolyzing technology based on rice husk. Another factory with annual production capacity of 1200 tons of briquettes was established in Butwal (1984) and a third one followed in Dharan (1984) with annual production of 600 tons.
Beehive Briquette Production Process
The beehive briquette is the most commonly promoted briquette in Nepal. It is formed through the use of pyrolizing (charring) technology. It relies on partial pyrolysis of biomass mixed with a binding agent, and made into briquettes by casting and pressing. It is commonly known as the beehive briquette due to the holes in the briquette that provide improved combustion. You can learn more about the beehive briquette by consulting our Resources page.
