Artificial Wood Chips/Smoke for smoking meat I am looking for alternatives to using wood chips for smoking meats.  I would like the process to actually smoke the meat.  Liquid smoke/marinades are not what I'm looking for.  

Has anyone heard of any projects or items that could be used?  I'm thinking of a more environmentally friendly way to smoke meats without relying on wood such as apple, cherry, hickory or mesquite.  The cost of obtaining these woods in some parts of the world make it cost-prohibitive.
I'm confused. 
You don't want fake smoke but you don't want to use wood? Are you asking for a synthetic substance you can burn that will not be worse for the environment than burning wood?

First of all- burning wood is not bad for the environment- that carbon has not been sequestered and so it would be released into the atmosphere anyway when the wood decayed.

Secondly- mesquite is a cancerous weed here in Texas and I encourage everyone to smoke with it to restore the damaged ecosystem.

Thirdly- You can't fake the taste of smoking with wood. That's the point. Even liquid smoke is actually made by distilling real smoke.
