Carbon Fertilizer is Super Biochar loaded with organic matter, carbon, and nutrients that is directly applied to soil, and blended with other fertilizers and soil amendments.

Carbon Fertilizer makes restoring soil carbon, organic matter, and biology simple and easy.

  • Dry granular particles provide a drop-in substitute for chemical fertilizers.

  • Inoculation with nutrients and organic matter is not required like wood biochar.

  • Compatible with dry fertilizer spreaders on farms, golf courses, and in households.


The Benefits of Carbon Fertilizer™

Carbon Fertilizer™ is a revolutionary bio-fertilizer made entirely from wasted bio-resources that is designed to sequester carbon and rejuvenate soils.

Made in the USA from locally sourced organic matter, carbon, and nutrients (biosolids and wood).

Sequesters carbon in soil, enhancing hydration and reducing erosion.

Pyrolysis process eliminates PFAS, VOC contaminants, odors, and pathogens found in biosolids.

High cation exchange capacity (CEC) improves nutrient capture, storage, and transfer to roots.

Minimizes nutrient losses from leaching and runoff, reducing the need for additional

Gradually releases nutrients to plant roots as needed, supporting healthy growth.

Promotes robust root growth by providing essential nutrients, oxygen, and moisture.

Accelerates early-stage plant development and boosts crop yields.

Organic matter enriches soil and fosters microbial and fungal proliferation.

Environmentally friendly process and soil application result in a negative greenhouse gas footprint. 

Sequesters its weight in greenhouse gas emissions when applied to soil, aiding in
climate mitigation.

How It Works

Carbon Fertilizer is more than a common fertilizer.  It’s Super Biochar that delivers nutrients to plants and feeds soil!

  • Delivering nutrients to plants.

    Its high cation exchange capacity (CDC) attracts and interacts with nutrients that are co-applied, or already in the soil; pulling them into a porous structure to avoid leaching and runoff. Roots are attracted to the oxygen, water, and nutrients in the biochar, and seek it out and tap it in the soil.  Nutrients and moisture are released “on demand” as the plant requires them for growth.

  • Feeding soil.

    Carbon Fertilizer’s high organic matter and porosity create an all-inclusive hotel package for microbes and fungi which fosters their proliferation in the soil.  Organic matter feeds the microbes and fungi to improve moisture content and nutrient retention.  Carbon Fertilizer’s porous structure provides a place for microbes and fungi to replicate after feasting on organic matter.

Saratoga Biochar

Carbon Fertilizer comes in four particle sizes:

Granular SGN 400
(average diam. 4mm)

Designed for agricultural and soil restoration applications: drop-in substitute for chemical fertilizers.

Granular SGN 200
(average diam. 2mm)

Designed for farm, lawn & garden, landscaping, horticulture, sod farms, soil restoration, and soil remediation: drop-in substitute for chemical fertilizers.

Greens Grade SGN 80
(average diam. 0.8mm)

Designed for golf courses and applications that require a smaller particle size: drop-in substitute for chemical fertilizers.

Seed Coating – Powder
(average diam. <0.5mm)

A powder used in coating seeds, plant propagation, and other applications that require a very small particle size.

Climate Friendly Process

The SBS facility employs a proprietary climate friendly process that beneficially recycles biomass and protects human health and the environment. 


Feedstock Prep

Biosolids and wood waste are sized, mixed, and sent to dryer.



Feedstock is dried utilizing heat generated from advanced combustion.


Dried feedstock is heated without oxygen to separate PFAS and other VOC contaminants from Carbon Fertilizer.

Advanced Combustion

Remediates PFAS and other contaminants separated by pyrolysis and generates heat for pre-drying feedstock.


Air & Odor Treatment

Employs benchmark air treatment to manage air emissions, odors, and our reputation.

Climate Change Tool

Carbon Fertilizer’s production and use generate three GHG emissions offsets, or credits, based on avoided and sequestered GHG emissions. 

Avoided Biosolids Disposal GHG Emissions Credit

  • Bringing biosolids to the SBS facility avoids GHG emissions that would otherwise be incurred through current biosolids disposal practices in New York. This includes the methane and nitrogen dioxide emissions associated with decomposition, GHG emissions related to transport, as well as the relative share of GHG emissions that incinerators and other disposal practices contribute.

  • Generates a 95% GHG reduction credit relative to SBS facility GHG emissions.

Carbon Sequestration Credit

  • Carbon Fertilizer use sequesters carbon in soil where it is needed to improve water and nutrient retention in perpetuity.  Carbon Fertilizer contains approximately 30% fixed carbon that is resistant to degradation for centuries (i.e., petrified).  

  • Generates a 106% GHG reduction credit relative to SBS facility GHG emissions.

Displaced Chemical Fertilizer Production Credit

  • Carbon Fertilizer use displaces chemical fertilizer as a direct substitute in crop production and avoids GHG emissions associated with chemical fertilizer production and transportation.

  • Generates a 36% GHG reduction credit relative to SBS facility GHG emissions.

Carbon Fertilizer’s life cycle GHG Analysis yields a 137% net GHG reduction after deducting SBS facility and transport GHG emissions.

In the GHG emissions context, being negative is a very positive thing as traditional energy has a positive GHG footprint and renewable energy, like solar and wind, typically have a carbon neutral life cycle GHG footprint.
