Answer:
Yes wood is a biofuel because a biofuel is anything that you can burn which is made from living things or their waste products ... :) LOL x
(DarthBismarck) Edit:
There's a number of factories going up around the planet at the moment that will take wood in any form and compress it into 'pellets' of varying size to act as a clean alternative to coal. As opposed to the toxins and pollution thrown out by coal-fire generators, these wood pellets are carbon-neutral, meaning they only emit an amount of carbon dioxide equivalent to what the tree itself would release should it have been allowed to naturally decompose.
What's better, when used in this form, the wood used in these pellets could be, have been, and in many cases currently are, the leftovers, remnants, and waste products from any industry that makes use of wood, from sawmills to the pulp and paper industry - one is as good as the others.
