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 USA from American organic matter, carbon, and nutrients (biosolids and wood).

Sequesters carbon in soil where it’s needed to improve hydration and reduce erosion.

Pyrolysis removes PFAS, VOC contaminants, odors, and pathogens that constrain biosolids use.

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

Reduces nutrient losses from leaching and runoff, and fertilizer use over time.

Slowly releases nutrients “as needed” by roots which seek it out in the soil.

Enhances root growth by supplying nutrients, oxygen, and moisture to roots.

Expedites early-stage plant development and increases crop yields.

Organic matter feeds the soil and helps microbes and fungi proliferate.

Climate friendly process and use in soil achieves a negative GHG footprint.

Sequesters its weight in greenhouse gas emissions when applied to soil.

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 three particle sizes:

Granular SGN 240

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

Granular SGN 220

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

Greens Grade SGN 207

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

Seed Coating – Powder
(< 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.

The SBS Facility

The SBS Facility located in upstate New York is designed to process 15% of New York’s biosolids and turn it into Carbon Fertilizer that restores soil.

Climate Friendly Process remediates PFAS and other contaminants that constrain biosolids beneficial use in agriculture and soil products.

Produces ultra-low air and odor emissions that meet NYS Climate Leadership and Community Protection Act (CLCPA) requirements and environmental justice considerations.

Helps solve New York State’s Biosolids Disposal Problem. 

Provides a Climate Change Tool that helps New York meet its ambitious climate change goals.

New York State’s Biosolids Problem

The SBS Facility substantially reduces NYS’s biosolids disposal problem by providing an in-state beneficial-use solution that meets New York’s rigorous environmental laws and regulations and helps achieve the State’s ambitious climate change goals. 

Biosolids generation already outpaces disposal capacity making NYS the largest net exporter of biosolids nationally.

Over 68% of biosolids are landfilled with an increasing amount destined for out-of-state landfills. 

NYS biosolids disposal options are declining as landfills and incinerators reach their end of life. 

NYS PFAS regulations further constrain recycling methods which beneficially utilize the nutrients and organic matter in biosolids.

NYS Climate Leadership and Community Protection Act (CLCPA) promotes diverting biosolids from landfills, limiting biosolids acceptance in landfills, and reducing environmental injustices associated with odors and air emissions from biosolids disposal and recycling.
