Various useful materials are contained in fisheries and agricultural waste. It has been, however, difficult to transform of the waste into resources, because the former one contain toxic heavy-metals bound tightly to heavy-metal-binding proteins or the latter one were constituted of chemically rigid structures caused by inorganic salts, respectively. During a sequential treatment of the waste with sub-critical conditions and microorganisms, toxic metals in fisheries one were released as free-ion forms and rigid structures in agricultural one were destroyed to fermentable mono-saccharides. These results suggested that fisheries and agricultural waste could transform to resources like feed for cattle and ethanol, respectively, by the sequential treatment.
