Our Story

BET began by acquiring the Conifer gasifier technology, building on a gasification heritage dating back a century. That foundation became an integral part of a new approach to converting biomass residuals into valuable products.

Through years of development, testing, and design, BET introduced its first Pyrolysis Rotary Drum (PRD) in 2020. That original machine remains in operation today.

The first PRD model, the PRD24, evolved into today's PRD1000. BET later developed the PRD3000 and PRD8000, increasing processing capacity while preserving the core qualities of the original design: durability, efficiency, ease of operation, and high-quality biochar production.

Today, more than 30 PRD systems and hundreds of gasifiers are in the field. These systems process a wide range of waste streams and high-moisture feedstocks, producing premium-grade biochar and thermal energy that can be used directly or recovered for electricity generation.

From the first prototype to today's installations, BET continues to build on the same purpose: practical, dependable technology that turns challenging materials into useful resources.
