Abstract
A material processing method produces a fiber product by anaerobic digesting of input material such as dairy flush to produce a gas product and a liquid and solid fiber product, by thereafter separating liquid components and solid fiber components of the liquid and solid fiber product, and by thereafter aerobic conditioning of the solid fiber components to derive the fiber product useful as a soil amendment in the manner of peat moss.
