Next-Generation Biomass Processing

Qualterra’s patented biomass processing technology combines time-proven gasification and energy generating processes with modern, automated control systems to convert biomass into renewable energy and biochar. The Biomass Processing Unit (BPU) is housed in a rugged, modular shipping container and paired with various input and output modules, and is adaptable to accommodate a variety of biomass types and site requirements.

Highlights of our BPU Technology

  • Cleanly eliminates biomass waste.
  • Designed for high silica field residue to produce unique biochar derived from crops.
  • Controlled parameters to get consistent product every time.
  • Deployable, portable and scalable to meet demand.
  • Fully autonomous, continuous feed gasification system.
  • Eliminates waste and produces clean, renewable energy.
  • Designed for high volume manufacturing.
  • Technology covered by three US patents.

Qualterra biomass processing technologies reduce agricultural waste by turning it into biochar, a beneficial soil amendment, that improves plant health. Additionally, energy created by the biomass processing unit can then be captured and utilized in a variety of capacities.

Biomass Processing Units Offer an Integrated Solution to Process Waste and Renew Soils

Carbon Sequestration through Biomass Processing

Most agricultural wastes, including those with high silica content, can be effectively processed using our Biomass Processing Unit, converting waste to a valuable soil amendment with roughly ¼ the mass of the original material. Our continuous flow design and remote monitoring means the system requires minimal management. Qualterra’s biomass processing engineers will work with you to integrate the Biomass Processing Unit into your existing systems, maximizing autonomous function. Unlike compost and other forms of biomass which degrade within years and release carbon dioxide, biochar stably sequesters carbon for hundreds of years, reducing the environmental impact of your agricultural enterprise.

Generating Renewable Energy

Syngas produced by the BPU can be used for heating or for generating electricity. It is frequently used to help offset energy costs of warehouses, greenhouses, or buildings.

Biochar Production

Qualterra’s BPU is designed to produce a high-quality, consistent biochar product. While biochar can also be used as a filter media, its most common use is as a soil amendment which can boost crop yields, enhance soil health, and reduce water and fertilizer consumption. The unique and porous structure of biochar retains water and nutrients, leading to reduced nutrient leaching and improved water and nutrient use efficiency. Soil structure is improved by increasing pH and organic matter, leading to improved soil aggregation and providing a suitable host environment for microbial activity. Root growth is increased, and the improved root surface area aids in plant nutrient uptake. Biochar is a stable carbon structure lasting thousands of years in the soil, removing it from the atmosphere and providing valuable benefits for the farmer. Qualterra’s BPU offers a reliable and eco-friendly alternative to process waste and the resulting biochar soil amendments can improve plant growth, health, and yield.
