Improving The Profitability Of Finfish Processing Waste: Options For Fish Processors With An Emphasis On Mechanical Deboning (Mincing), Hydrolysis (Liquid Fertilizer Production), And Composting

About half of what comes into a fish processing plant leaves it as product; the other half leaves as waste. Disposing of this waste has become a serious problem in recent years as communities and legislatures have taken action against air and water pollution. This report for the operators of small- to medium-sized plants describes current technologies for increasing the value of fish processing plant waste and decreasing pollution. It also discusses the appropriateness of these technologies, their cost and implementation. Marketing efforts and product development are emphasized because although technology alone may be able to reduce pollution, only the integration of technology with product development and marketing can increase profits for the processor. The technologies discussed yield human food products, feed and fertilizer products, and a variety of minor products. The focus is on mincing, hydrolysis, and composting options.
