Let’s reverse climate change.

If we stop fossil fuel emissions tomorrow, global temperatures will still rise significantly. There’s simply too much CO2 in the atmosphere. Recent studies suggest up to ten gigatons globally must be sequestered by 2050 to prevent catastrophic climate impact. Climate experts estimate that biochar alone could address as much as 40% of the needed carbon removal, while simultaneously mitigating other environmental issues.
  • Every ton of Persist biochar removes three equivalent tons of CO2 from the atmosphere helping to reverse global warming.
  • Persist products are made by VGrid, an innovative clean energy company producing sustainable electricity from agricultural and forestry waste.
  • This green energy reduces our reliance on dirty fossil fuels while decreasing landfill waste.

How VGrid is fighting climate change with Persist

Persist™ PAF and Biochar provide a 14% yield increase in marketable strawberries per acre.

      • Outdoor production trial conducted by Holden Research and Consulting (Ventura County, California, U.S.A.); September – December 2022.
      • Before planting, Persist™ Biochar was placed in the slot at a rate of 480 lbs/acre. Persist™ PAF liquid was applied at 1% dilution with a backpack sprayer at a total rate of 3.5 gal/acre (four applications total).
      • Results compared to grower’s standard regimen. At planting, all treatments received controlled release fertilizer and in-season applications of nitrogen and phosphorous, along with foliar pest control.

Persist treatment produces 7% more soybean plants per acre and 4% larger plants.

* SynTech Research Group (Jefferson City, Iowa, U.S.A.)
Treatment included a unique blend of Persist PAF liquid and a biochar tea. Two liquid applications were made: One at pre-plant and the second at six weeks after planting.

The Persist™ Biochar Difference


Persist biochar is manufactured in a high-temperature gasification process that maximizes the removal of volatile organic compounds (VOCs) from the biomass. This proprietary process also yields a biochar with greater than 90% fixed carbon content, which is significantly higher than most other brands of biochar. Persist has low ash content, consistent particle size distribution, and is made from 100% California-grown waste pistachio shells, which would otherwise go to the landfill.


Persist’s proprietary high-temperature production process also creates an extremely porous biochar with an intricate network of microscopic pores, cavities, and channels. The result is a massive “surface area-to-volume” ratio, which maximizes the water holding capacity and nutrient binding capabilities. One ounce of Persist™ in fact has a surface area equal to 1-1/2 football fields. Persist’s surface area of 200-300 m2/g compares to other biochar at <20 m2/g.


Biochar is an effective method for capturing carbon that would otherwise enter the atmosphere. But how much carbon is captured and for how long is not the same for all biochar. Persist is over 90% fixed carbon, meaning that more carbon is captured per pound compared to others. Additionally, if the oxygen-to-carbon (O:C) ratio of biochar is less than 0.2, then the half-life is greater than 1,000 years.  With an O:C ratio of 0.05, Persist provides significantly longer sequestration.

Biochar saves water, reducing the impact of drought.

49 Day Drought Trial with Flowers

Before and after comparison

A series of studies were conducted to evaluate the water holding capacity of biochar. In one, flowers were planted in two self-watering pots, which were then top-watered and filled.

After 15 days, the water level indicator in the non-biochar planter dropped significantly but remained virtually unchanged in the biochar-amended planter, even after 30 full days of no water.

After 49 days of no additional watering, the flowers in the biochar-amended pot were still in bloom and the leaves were green and healthy.  Flowers in the non-biochar pot were dead.

NEW Micronized biochar for fertigation, drip irrigation, and foliar spray systems.

  • Carefully screened particles less than 75 microns (0.075 mm) designed for liquid suspension and application.
  • Enhances dispersibility of biochar in soil for more precise nutrient delivery while reducing loss from volatilization.
  • Micronized particles further improve water retention, nutrient availability, and microbial activity in soils.
