A British man had the idea to use the great quantity of fallen leaves in autumn to make them “logs” for fire.
One million tonnes of leaves fall every year in the UK, and Peter Morrison, aged 45 years, being sick of collecting the leaves, each year, from his yard in Birmingham, thought to turn them into a “green” fuel to replace wood.
He started by creating a tablet the size of a coin, which, lited, generated enough heat to boil a liter of water.
Currently, a company called Biofuels International Limited (BIFL) produces cylindrical leaves “logs” – called Leaf Log – with a length of 28 cm, which are already in British shops and are used as fuel in homes.
The “Leaf Logs” ignite easily and burn very efficiently, providing 28,000 kilojoules (the best coal give approx. 29,000 kilojoules)
