RWEDP Report No.23, 1996
The International Workshop on Biomass Briquetting was organised by the Department of Chemical Engineering of the Indian Institute of Technology-Delhi. The Workshop was sponsored by the Technology and Development Group of the University of Twente, The Netherlands, and the Indian Renewable Energy Development Agency Ltd., India. The Workshop reported the main results of the Biomass Densification Research Project, which was jointly implemented by the two named universities and two private sector companies (Solar Sciences Consultancy Pvt. Ltd, and DENSI-TECH). Results from briquetting activities in other countries in Asia were also reported, and various technical and financial aspects of briquetting were addressed in the International Workshop.
It is clear from the Workshop that substantial progress has been made in briquetting technology and practices in recent years. Briquetting of biomass residues for fuel is an important option for substitution of wood and loose biomass residue fuels, under certain conditions. However, the option should be carefully evaluated and any implementation should be based on a thorough understanding of the requirements and constraints.
During the workshop a variety of presentations was made dealing with resource availability, experiences with briquetting technologies, prospects for marketing the products, etc. Given the fact that large amounts of agro- and forestry residues remain unused in the region, it was recommended that efforts be made by various national and international organisations to promote the technology (see also Biomass Briquetting: Technology and Practices).
