ABSTRACT:
Processes are provided for the thermophilic digestion (55.degree. C. to 65.degree. C.) of chitinous wastes to produce a solubilized form of chitin that may be applied to plants to stimulate their resistance to disease and attack by insects and fungi. Also provided are processes for treating a combined waste, including a waste containing chitin and an organic waste, to produce a substantially human and plant pathogen-fee product that may be used not only to stimulate plant resistance, but also to act as a fertilizer. The thermophilic digestion processes may be carried out with ubiquitous organisms, under at least marginally aerobic conditions, and preferably at a near-neutral pH.
