Skip to Abstract

Transporting livestock manure to nutrient deficient fields can often be cost prohibitive without manure processing. Pyrolysis converts manure solids into biochar resulting in significant mass and volume reduction, while retaining high nutrient value. This fact sheet introduces the basics of pyrolysis technology, discusses the benefits and end uses of manure-derived biochar, and provides an overview of cost and technology limitations.
