"I grew up in the logging business,and always believed we needed to collect the MASSIVE amount of scrap left behind....there is a dump truck load of useable material around that Cat"
I co-own a shutter making shop and the amount of sawdust we have to get rid of is incredible. If there was an economical way to utilize it for fuel conversion, thousands of tons of sawdust could be collected from woodshops every week.
Read about another process of pelletizing sawdust,similiar to what they do with corn waste,to use for heating.
