A pioneering Cambodian business is turning leftover coconut shells and other waste into clean-burning briquettes for use as cooking fuel in Phnom Penh's homes and restaurants. Most Cambodians cook on wood charcoal, which contributes to the country's rampant deforestation and air pollution. Led by Carlo Figa Talamanca, Sustainable Green Fuel Enterprise can scarcely keep up with demand. Users like Lin Haiy, who runs a family restaurant explains why the briquettes are so popular. "The old charcoal used to burn your clothes and it was smoky and dirty. This is much better: it burns longer".
