Exeter Charcoal Retort

Exeterra, LLC produces the Exeter Charcoal Retort for distribution in the United States, Canada, Mexico, and the Caribbean. We accomplish this through a license from the Carbon Compost Company of Exeter, Devon, England.

The Exeter offers solutions for the economical conversion of available biomass into valuable products by transforming wood into lump charcoal and biochar and livestock and wild game bones into bone char.


IMG_3357The Exeter is particularly useful for natural and organic farms, small forest enterprises, compost and greenhouse operations, and livestock processors.

It can merge into existing operations, or be used to create a stand-alone business that generates revenue from low-value biomass.

Processing livestock and game bones in an Exeter is a great way to produce a fertilizer rich in calcium and phosphorous.

For on-farm use, or to sell for revenue as a locally-made soil amendment.
