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.
