Functional Biocarbon Materials

Program Overview

Carbon is an essential element in nature. Functional biocarbon materials are developed to utilize waste biomass resources as high value carbon-based product for a variety of applications. For example, biochar is a stable, carbon-dense material that can sequester atmospheric carbon dioxide for millenia while providing benefits to soil, water, and plants. Other materials can also be developed, such as sorbents for water and air purification, composite fillers, and battery components.

NRRI leads an interdisciplinary program in pyrolytic technologies to produce functional biochar materials through substantial investments in biomass thermal processing equipment at the bench and pilot scales. This is supported by unique capabilities in materials characterization and chemical modifications.

Collaborations with external partners include:

  • Urban, agriculture and forest soil enhancement
  • Water treatment
  • Landfill remediation

NRRI is also pursuing new opportunities in metallurgy, energy, and infrastructure.

NRRI R&D programs have produced these materials from wood and agricultural residuals over the past ten years with pilot facilities designed to treat biomass for energy applications. Further strategic investments in equipment and facilities allow us to produce more technically challenging materials that require stringent processing conditions, and focus on the stepwise scale-up from the laboratory to the pilot scale.

Program Goals

  1. To establish a diverse and sustainable biochar industry for Minnesota.
  2. To develop co-production of bioenergy with biochar.
  3. To assist partners with biochar demonstrations aimed at encouraging carbon sequestration, soil improvement, water treatment, and sustainable management of forest and urban trees.
  4. To work with external partners to establish biochar specifications for biochar used in different applications.
