Back in 2006, a campaign was launched to plant one billion trees every year. In the first five years alone, over 12 billion were planted, and the campaign rolls on today.
The Billion Tree campaign is now managed by the United Nations Environment Agency and efforts like these have had an important role to offset the billions of trees cut down every year.
Of course, all this wood processing creates sawdust and there’s a long list of uses for this by-product including fuel briquettes, animal bedding, mushroom growing, soil amelioration, ‘smoking’ food, building products and more.
One of the latest development involves researchers at Katholieke Universiteit Leuven (KU Leuven) in Belgium, the Leibniz-Institute for Solid State and Materials Research in Dresden, Germany, and the chemical engineering department at the California Institute of Technology in USA.
They have managed to convert sawdust into building blocks for gasoline.
