Hi Robert

>From what country are you? What are the resources available in your
community? Who are your intended clients/customers.

To begin with, you may visit the website of the Legacy Foundation. They
have very rich library of the briquetting technologies and the on the
ground experiences.

You may also see my work in the report in the www.holeyroket.wordpress.com.
Briquetting and pelletizing should come together with a serious production
of appropriate designs of stoves. I hope these sites will help you.

Feel free to call for inquiries after.

Best regards

Jed Guinto
