How it Works
Industrial, continuous flow, energy efficient engineering. Through highly disciplined development, which respects industry standard technology readiness levels (TRLs), Biowave™ was developed as a disruptive technology for the waste treatment sector.
Our early applied research and development focused on the fundamental interactions of microwave energy on organic feedstocks.
This research output provided the foundation for rigorous pilot scale and now, industrial, commercial scale deployment.
Microwave pre-treatment of organic waste for enhanced renewable gas production enables greater yields, in a faster time, for less cost.

Common Questions
Biowave™ can treat any kind of organic waste stream from 1 to 25% total solids content. We work with energy-dense, but poorly degrading organic wastes from municipal wastewater treatment plants, dairy processors, industrial, and food and beverage processors. Talk to us about your needs here.
Biowave™ thermal treatment is more energy efficient than conventional thermal methods because it uses microwaves absorbed by polar compounds on a molecular level to heat the feedstock. The resulting vibration of polar compounds generates heat in situ and uniformly across the feedstock material. This leads to rapid heating and faster chemical reactions.
By contrast, conventional heating relies on conduction and convection from an external heat source throughout the material and results in uneven heating and the formation of hotspots and cold spots. Microwave heating incurs lower energy losses than conventional heating and saves time and energy.
Biowave™ pre-treatment improves the hydrolysis of macromolecules like proteins, lipids, carbohydrates, and polymeric substances, and reduces the particle size of solids. These effects make the feedstock more bioavailable to the microorganisms in AD. Results are accelerated gas production and higher methane gas yields. By facilitating the hydrolysis of the feedstock, shorter hydraulic retention times or higher organic loading rates are more accessible.
Biowave™ reduces the concentration of recalcitrant compounds, such as LCFAs and EPS. For example, we have demonstrated up to 66% reduction of LCFA in dairy fat waste. These compounds are inhibitory to AD. Breaking these compounds down using Biowave™ makes the energy-dense feedstock accessible to AD microbes with no inhibitive effects.
