Impact bioenergy

Based in Washington, Impact Bioenergy manufactures portable systems that convert organic waste to produce electricity and fertilizer. The company started manufacturing its own biofertilizer product called “ProBiotic Plant Food” (PBF)  in July 2020. PBF is a compost biofertilizer, which is made by first creating a “smoothie” from waste food such as spent yeast, curds, whey, and trub. This is then digested by microbes in a 30-day process to convert it into PBF. The final product is dried and pulverized to create a mix called “PBF Mix No 7.” Based on a trial conducted by Forest Garden Farm for a butternut squash tree, PBF increased yields by almost 30% compared to using a standard fertilizer. 

The company also adds fish bone meal, poultry feather meal, biochar, and mealworm frass to the base product to produce different blends of PBF, which is offered as a dry blend or concentrated liquid blend that can be mixed with water to make a fertigation liquid. PBF initially was available to B2B customers on a subscription basis and then later targeted B2C customers selling online via ecommerce sites such as Amazon.
