This company is gathering pine needles from an invasive species, combining with sawdust and making briquettes as a replacement for coal.
“India produces millions of tons of waste each year in agriculture and forestry. But this biomass contains much more than just rubbish. That’s something groups in northern India have realized too. They’re now producing briquettes from the biomass and selling them to local brick kilns.”
Coconut Shell Briquettes
“Wood is the main source of energy in Cambodia, which has resulted in widespread deforestation. In response, French NGOs have developed an alternative – charbriquets made from coconut shells and dried organic waste. The fuel does not use chopped lumber – giving it a clear advantage. The briquets are inexpensive and burn longer than wood. Factory manager Carlo Figa Talamanca who took over the company from his former employers now wants to reach a wider market, He is working with a French aid group that turns students into a sales force.”
