Improve Your Composting Process

Applying 10% Persist Biochar by volume and a 1:500 dilution of Persist PAF to composting piles significantly increases microbial activity and aeration while lowering bulk density and moisture loss.  As a result, compost matures faster — improving overall yields and lowering long-term processing costs.

Reduce GHG Emissions

Multiple studies have concluded biochar decreases greenhouse gas emissions, including nitrous oxide, methane, and ammonia from composting piles. Biochar also mitigates unpleasant odors and reduces leaching, preserving valuable nutrients in the compost where they belong.

Enhance Compost Effectiveness

When added to soil, compost amended with biochar and PAF will see increased microbial activity and diversity, improved nutrient retention, higher humification, and increased production overall. The water holding capacity also increases, further improving compost's effectiveness in drought-stricken soils.

Ultra-porous Persist™ Biochar provides superior performance

Our proprietary manufacturing process creates an extremely porous biochar with an intricate network of microscopic cavities and channels. The result is a massive surface area-to-volume ratio, which provides superior water holding capacity, nutrient binding, and overall microbial benefits. The porosity of Persist biochar is significantly greater than most other products on the market.

Persist™ Biochar is now a USDA Certified Biobased Product.

Let's reverse climate change.

Biochar helps to reverse climate change.  Persist™ biochar is produced from 100% California-grown pistachio shells – a waste product sent to the landfill – that would otherwise decompose and release CO2 back into the atmosphere. This CO2 is captured in the biochar in a stable form for over 1,000 years.

Composting is a fantastic use for organic waste …

Persist™ Biochar + Persist™ PAF make it better.

  • Faster composting = increased yield
  • Increased aeration
  • Increased microbial action
  • Reduced leaching
  • Reduced odors
  • Reduced harmful gas emissions
  • Reduced Nitrogen (N) loss
  • Improved humus content
  • Reduced ‘clumping’ in compost pile
  • Enhanced plant yields

How to use Persist™ Biochar and Persist™ PAF in composting.


To start, add approximately 10% biochar by volume and apply a 1:500 dilution of PAF to a new compost pile (≈ 1/2 tablespoon per gallon). Persist Biochar and PAF can be added between layers of organic matter or worked into compost, with the goal of establishing a uniform distribution.


As compost is turned, or from time-to-time in the process, add an additional 3-5% biochar by volume. To maintain elevated microbial activity and to prevent compost from drying, apply an additional 1:750 dilution of Persist PAF (≈1 teaspoon per gallon water).


The beneficial microorganisms in compost need both Carbon (C) and Nitrogen (N) to thrive.  Maintaining a C/N ratio between 25:1 and 35:1 is ideal.  When biochar is included in compost, Nitrogen loss is reduced, so it's important to ensure this ratio is in the proper range.

Persist™ Biochar Advantages

CAUTION: Not all biochars are the same. Biochar characteristics, including carbon and ash content, should be verified with a lab analysis.

  • Produced from 100% California-grown pistachio shells -- a waste product otherwise destined for the landfill.
  • Higher porosity and surface area ratio compared to other biochar on the market.
  • Absorbs and holds water in soil 6x longer.
  • Carbon content greater than 90%, which is significantly higher than most other brands of biochar.
  • Ultra-low ash and VOC content.
  • Consistent particle size distribution.
