Contribution of Biotechnology-Based Valorisation of Forestry By-products to Achieving SDG14

Abstract

It is estimated that the largest share of future food fish will come from aquaculture production and that sustainable aquaculture is a precondition to realising this potential. Sustainable aquaculture will also play a key role in achieving several of the targets set out in SDG14. It is now established that most of the aquafeed ingredients used today are not sustainable and cannot support the projected growth of the sector, hence the need for sustainable alternatives. Sustainable aquaculture is multidimensional, therefore, this chapter focuses on sustainable feed ingredient sourcing. The authors explored a group of highly promising emerging novel ingredients known as microbial ingredients (MIs), means of producing them and how they can help achieve sustainable aquaculture and SDG14 targets. Specifically, the chapter narrows down on producing MIs from Norwegian spruce tree hydrolysates using a biotechnological approach and how Foods of Norway, a centre for research-based innovation at the Norwegian University of Life Sciences is leading efforts to produce feed-worthy MIs from industrial and agricultural by-products through biotechnology-based valorisation. MIs such as yeast, fungi, and bacterial meal can support the growth of Atlantic salmon without compromising the health of the fish. Thus, MI has a net positive impact on climate and can help achieve some targets in SDG14 by reducing pressure on marine resources used as fish feed ingredients. Suggestions on how to address current bottlenecks in scaling up MIs have also been provided in the chapter.
