Biochar Filtration Media

Biochar (aka Evergreen BioCarbon) is produced from clean, southeastern US pine biomass and is composed of >80% fixed carbon. BioCarbon is very porous with abundant internal surface area and high adsorption capacity. BioCarbon has undetectable amounts of live microorganisms due to production temperatures >800o C. As an agricultural amendment or remediation media, it can provide benefits in the soil for >100 years because it resists decay. BioCarbon is also called Activated Biochar.

Qualities Some of the potential benefits of Evergreen BioCarbon include:

  • High adsorption capacity
  • High carbon content
  • Long half-life (100s of years)
  • High water-holding capacity
  • High nutrient retention capacity
  • High pesticide retention capacity
  • Improvement of soil quality and water retention
  • Increased beneficial microbes by providing substrate and refugia
  • Increased Cation Exchange Capacity (CEC)
  • Can enhance crop growth with less agronomic inputs

Pollutants: Biochar Takes Up and Adsorbs:

  • Nutrients (can be designed with denitrification in mind)
  • Heavy & Dissolved Metals
  • COD & BOD promoting Organics
  • Hydrocarbons
  • Bacteria

Biochar filters and breaks down even more with microbial (bacteria, fungi, algae, and protozoans) additives to the media in a balanced consortium based on pollutants of concern and site specifics.
