Abstract

The stabilization of bio-organic sludges such as those derived from sewage, meat works or dairy works effluent, against putrefication or microbial decomposition is disclosed. The stabilization is achieved by adding a bio-organic material, such as coir fibre, straw ,flax and/or ground bark and/or a source of carbohydrate. Preferably, the final concentration of water in the product is at least 15% by weight water, with a preferred upper limit of 70% by weight water.
