To reutilize foodstuff waste products containing much of salt-components and oil-components as feed for livestock, fertilizer, etc., by subjecting the waste products to recycling treatment.
The foodstuff waste products containing the salt-components, oil-components, and moisture discarded from foodstuff factories are crushed by a disposer 2 and are subjected to a solid-liquid separation by a solid-liquid separating machine 8. The solid contents obtained by the solid-liquid separation treatment are dried by a drying machine 15 and a waste water is introduced into the disposer 2 and is utilized as washing water. The tail gas from the drying machine 15 is utilized as a heat source for heating the washing water and the washing water is introduced as warm water to the disposer 2 to wash the foodstuff waste products. Since the salt-components and oil-components of the foodstuff waste products are efficiently washed out, the foodstuff waste products are effectively recycled and reutilized as the feed for the livestock and others.
