As the market for biochar and bio-energy matures, the company’s emphasis on a durable, self-contained business model and a commitment to scalability offers a distinct proposition for producers.

The Evolution of a Technology

The foundation of BET’s technology traces back to a fascination with gasificationGasification is a high-temperature, thermochemical process that converts carbon-based materials into a gaseous fuel called syngas and solid by-products. It takes place in an oxygen-deficient environment at temperatures typically above 750°C. Unlike combustion, which fully burns material to produce heat and carbon dioxide (CO2​), gasification More and high-temperature processes. The company’s origins are rooted in a partnership between Henry Giesbrecht, who developed a keen interest in the field from a young age, and Mark Leid in Versailles, Missouri, who had acquired a patent for a system with pre-cast grates. This collaboration led to a shift from low-temperature gasification to high-temperature applications, ultimately culminating in the invention of a pyrolysis system that incorporated a rotary drum. This evolution created a core technology designed to withstand extreme heat, a foundational element that defines BET’s current product line.

A central feature of BET’s pyrolysis technology is its capacity to process wet and green biomass without the need for pre-drying. This capability addresses a common logistical and energy-intensive hurdle in the biochar production process. The system utilizes the moisture in the feedstock, converting it into gas that is then used to heat the system itself, a process that is proprietary to the company. This technical approach streamlines the input process, allowing producers to focus on feedstock acquisition rather than costly and time-consuming preparation. The company’s technology is built on a single core design, available in different scales to meet varying operational needs. The PRD 1000, PRD 3000, and PRD 8000 units are named for their processing capacity in pounds per hour. This approach allows clients to select a system that aligns with their specific production volume requirements without compromising on the underlying technology.

Operational Philosophy and Manufacturing

Operationally, BET’s systems are engineered for sustained performance. They are designed for continuous, 24/7 operation, with the company recommending 320 operating days annually. This preference for continuous use stems from the equipment’s refractory lining, which performs optimally when consistently heated and avoids the stress of repeated heating and cooling cycles. The headquarters primary manufacturing facility is located in Versailles, Missouri, BET also has a small office in Canada to help support the Canadian market as well.

The company’s target market is broad, encompassing any entity facing a waste management challenge that can be converted into energy. BET’s systems have demonstrated versatility with a range of feedstocks, including pecan shells, walnut shells, sawmill waste, hemp, and rice hulls. A notable example of this application is the case study of Metzler Forest Products in Pennsylvania, a client that employs a BET PRD 10000 unit to process sawmill waste. The system not only produces biochar but also generates heat, which Metzler harnesses to dry firewood. This integration has reportedly resulted in the displacement of over 200,000 gallons of LP gas annually, saving the company over half a million dollars. This case illustrates the potential for BET’s technology to generate a dual revenue stream from both biochar and heat reclamation.

A Focused Business Model

BET’s business model is centered on the manufacturing and sale of equipment, a deliberate strategy to avoid potential conflicts of interest. The company explicitly chooses not to engage in joint ventures or take a percentage of biochar sales or carbon credits from its clients. This approach aims to allow BET to focus on providing consistent support and to maintain a transparent relationship with all of its clients. Derrick Giesbrecht, the company’s COO, notes that this model allows them to focus “on equipment building… and to be able to provide everybody equal opportunity”. The company suggests that a one-year return on investment is “very, very attainable” for clients who have secured a decent offtake agreement for their product and are participating in carbon credit markets.

The systems are also equipped with full automation, remote monitoring, and control capabilities. This feature enables clients to manage operations efficiently and receive support from BET’s team, which provides a full parts list and spare custom parts that cannot be sourced locally. This practice is intended to minimize downtime, which is a critical concern for continuous-flow operations.

Challenges and Future Outlook

Despite its successes, BET faces challenges, particularly in the energy reclamation aspect of its technology. The company has partnered with Boiler Systems for thermal production and Electrotherm for electricity generation. However, a key challenge is finding an “affordable power generation system” that can convert hot air into a substantial amount of electricity at a reasonable price point. A further complication is that certain electricity grids,, do not accept excess power production from these types of facilities.

The company’s growth trajectory is focused on strategic expansion. BET’s near-term goal is to establish market dominance within the United States before expanding its presence internationally. They have an interest in pursuing projects in the UK and Eastern parts of the world. A driving force behind this vision is a belief in the future of decentralized power grids. Giesbrecht envisions a future with “a lot of many grids instead of one big grid,” a network that would enhance security and sustainability. In this model, biochar production facilities would act as key drivers of these localized energy systems.

Looking to the future, BET is confident in its ability to support large-scale projects and continue to refine its technology. The company maintains that its systems are “high quality American-made.” Giesbrecht attributes the company’s success to this combination of simplicity and capability, stating that the systems are “stupid simple, but complex to a point where we can take in green and wet material.” This philosophy of building durable, effective equipment without unnecessary complexity appears to be a core tenet of their approach.

BET’s operational footprint currently spans from Florida to Washington state, with gasification clients also located in the UK. The company plans to be a sponsor at the upcoming North American Biochar Conference and will have a small unit on display. This engagement is part of an effort to increase exposure and provide an opportunity for prospective clients to see the technology firsthand and learn more about biochar production.
