HATCHERY WASTE AS A RESOURCE

摘要

In some parts of the world large quantities of waste matter are discharged into the sea from hatcheries located along the coast. However, as some operators have discovered the waste can also be of great benefit in the agricultural sector."If the waste is collected and used as fertilizer in greenhouses, in agriculture or is processed into biogas, it constitutes a resource and not a problem," says Ole-Kristian Hess-Erga from the Norwegian Institute for Water Research (NIVA). "This use of waste matter will improve the resource utilization, reduce the environmental impact and increase profitability and sustainability for both the fish farmers and the collaborating industries," he says.
