After conversion the biochar is crushed and screened into chip, medium, small and powder sizes, each optimized for distinct applications.
Improves soil structure
Retains nutrients
Reduces water consumption
Balances soil pH
Please note: unlike those that sell biochar by weight, we sell by volume, because biochar absorbs almost 6 times its weight in water, which is not fair to the customer.
The biochar production process begins with the raw, dry biochar entering the crusher, where it is broken down into smaller, more manageable pieces. These crushed biochar pieces are then fed into a four-output screener, where they are separated into four distinct sizes: chip, medium, small, and powder.
Each size has its unique characteristics and applications, making them versatile products for various industries. The biochar then undergoes further processing, including drying and activation, before being utilized in agriculture, environmental remediation, or other applications.
We sell our biochar in 1 cubic foot bags for the home garden retail market, and for our wholesale customers requiring truck or container loads, the biochar is bagged in 1 cubic yard super sacks.
When making a biochar size selection please note that for agricultural use including home gardens, the Chip and Medium sizes are used the most. For use as an additive to concrete, plastics, asphalt, cardboard pulp and for its many other industrial uses, see the size table below and fill out the request for consultation and quotation form.
