Biochar helps the soil retain water and nutrients and provides a great base for the soils microorganisms.  California produces half of the fruit and veg of the entire US. That creates millions of tons of waste, such as nut shells. We use this waste, and up cycle it into a carbon form called biochar. This biochar, when mixed with nutrients, helps anchor the good things near the roots, where the crop needs them.  Our only product is biochar, and that's what we focus on. No oils, gases, electricity or anything else. Just a good clean carbon for the soil.  Our production is local - the nut shells travel less than 50 miles from where they grew. We strive to be efficient.
