BET’s PRD technology provides continuous, automated biochar production for commercial and industrial applications. Designed to process a wide range of biomass and organic feedstocks, PRD systems deliver reliable operation, high-quality high-carbon biochar, and scalable production from the PRD500 through the PRD8000.
Continuous systems designed for projects ranging from smaller commercial operations to high-capacity industrial facilities.
Process suitable biomass with moisture levels up to 60% without the need for pre-drying.
Designed for 24/7 production with automated controls, remote monitoring, and minimal operator involvement.
Transform forestry residuals, wood waste, agricultural biomass, and other suitable feedstocks into valuable, high-carbon biochar while reducing landfill disposal.
PRD500 Biochar Production System — Smart. Small. Continuous.
Compact biochar equipment designed for smaller commercial projects requiring reliable, automated, continuous biochar production.
The PRD converts waste into biochar, energy, and carbon credits—efficient, continuous, and built for impact.
Turning waste into profit—biochar, energy, and carbon credits with every rotation.
Watch the PRD system transform wood residues into high-quality biochar, showcasing Metzler Forest Products’ commitment to innovation and resource efficiency.

In addition to our PRD biochar production equipment, BET offers a proven line of biomass gasification systems for commercial and industrial thermal energy applications. Designed to utilize wood waste and other suitable biomass feedstocks, BET gasifiers provide reliable, high-temperature renewable energy for a wide range of applications.
Two PRD3000 Systems with Hurst Boilers — Rice Hull–to–Biochar Conversion for Cold Steppe in Arkansas
This installation for Cold Steppe in Arkansas pairs two PRD3000 units with Hurst boilers to convert rice hulls into high-quality biochar while providing dependable thermal energy. The system efficiently converts rice hulls into biochar, lowers fuel costs, and delivers carbon-negative operation while generating valuable carbon-credit revenue.
