Book (stand-alone)Production and utilization of fish silage
A manual on how to turn fish waste into profit and a valuable feed ingredient or fertilizer
2018Also available in:
The processing of fish leads to a significant removal of parts of the fish, such as heads, bones, guts, etc., these parts can represent between 30-70% of the fish. The fish silage process transforms fish waste into a liquid mix of hydrolysed proteins, lipids, minerals and other nutrients, easily digestible by both terrestrial and aquatic animals. It can also serve as an excellent fertilizer. Fish silage could make a difference in terms of; i) environmental impact - by reducing levels of waste, ii) animal health - by providing nutrients and bioactive components, iii) economic gains - as waste is converted into a valuable product that can replace expensive feed ingredients, or be used as a fertilizer. This manual will provide technical guidance and explain each step and main principles of production and utilization of fish silage. -
Book (stand-alone)Fish silage production and use in the Caribbean: Feasibility study for Barbados and Saint Kitts and Nevis 2020
Also available in:
No results found.It is estimated that per year in Barbados, 585 tonnes of fish waste are generated at the two main public fish markets, and 936 tonnes of waste are generated at private fish processors across the island. Therefore, Barbados produces an aggregate of 1 521 tonnes of fish waste annually. At present, approximately 90 percent of fish waste and by-products are discarded at the landfill. To produce fish silage on a large scale in Barbados the baseline cost (based on a 90 percent yield rate) is estimated to be USD 265 920, excluding the cost of fish waste and acids. Sales revenues based on competitor prices range from USD 528 485 to USD 2 044 900. During the fish silage demonstration workshop held from 23 to 26 July 2019 in Bridgetown, the cost of small-scale production (100 kg) was estimated to be USD 900 and USD 254 when using the chemical and biological methods, respectively. The existing regulatory framework has the potential to facilitate the production and utilization of fish silage. However, clearance and permission may have to be institutionalized in order for fish silage to be produced and utilized in, and or as, animal feed. These conclusive findings subsequently prompted FAO to engage in a partnership with the Caribbean Agriculture Research and Development Institute (CARDI), to develop the silage-based feeds and document their effects on the growth performance of select animals. -
ProjectBananas in Pakistan's Bioeconomy: Transforming Waste into Textile: Project Document 2024
Also available in:
No results found.As a top-ten textile-producing nation with existing commitments to reform its textile industries and agrifood sector, Pakistan presents a prime opportunity to pilot transformative innovations upstream in its textile supply chain. Pakistan’s textile value chain (VC) is heavily dependent on cotton with substantial chemical use and a high-water footprint. Pakistani cotton production has fallen from 11 million bales (2018) to 7 million bales (2022). Industry is urgently seeking viable alternatives to reduce its dependence on imports. Pakistan is also a significant producer of bananas, producing approximately 150,000 tonnes annually with strong growth potential. This project will support institutionalizing sustainable and circular bioeconomy principles in Pakistan’s banana production. The banana plant’s significant biomass pseudostem results in substantial volumes of agricultural waste.
