In-Depth Information
This method could also lead to the achievement of green growth via the promotion of
resource recycling, which is a current goal in Korea (Mathews, 2012).
In addition, this
process could address impending problems concerning the release of fishery wastes into the
sea.

ONCLUSION
This chapter examined the possibility of using biodegraded culture broths of seaweed
wastes as a liquid fertilizer. The profiles of the major reaction parameters during the
biodegradation indicated that the stable metabolic reactions of seaweed polysaccharides took
place and that the 4-d biodegraded culture broths of three different types of seaweeds
exhibited comparable fertilizing ability with the commercial fertilizer with non-phytoxocity.
This finding implies that the culture broths of seaweeds adequately contain plant-growth-
enhancing compounds, including oligosaccharides, amino acids and mineral elements.
Together with fishery wastes, therefore, this successful reutilization of seaweed wastes
accomplished perfect resource recycling, exhibiting a zero-emissions process. In addition, the
reutilization of fishery wastes, including seaweeds and fish, as a liquid fertilizer can save
money and reduce environmental pollution by the replacement of chemical fertilizers.
Furthermore, this result addresses the impending problems that are related to the release of
fishery wastes into sea and to loss recovery.
