The major findings regarding the production of biogas/biomethane from fish waste (WP1) was not only in the testing of some organic streams but also in the development of a standard method. It is now possible in Iceland to test diverse products for biogas production. Skýrsluna má nálgast hér.

This project is a collaboration between ReSource International ehf. (RSI) and the Innovation Center of Iceland (ICI). ICI has been working on many energy projects related to production of bio-diesel, methane, methanol and hydrogen. There are good facilities and knowledge at ICI to do experiments and measurements on liquid biofuels. RSI has also great experience in running projects related to methane production and designing equipment and measuring devices for monitoring biogas production. In addition, the company RSI has recently built within the company incubator of the ICI, the only operating laboratory specialized in biogas in the country, offering a great opportunity for collaboration between the two organizations.
The project main goal was to determine the feasibility of using by-products from the fishery industry in order to produce biofuels (Biomethane and Biodiesel).
The major findings regarding the production of biogas/biomethane from fish waste (WP1) was not only in the testing of some organic streams but also in the development of a standard method. It is now possible in Iceland to test diverse products for biogas production. The production of Biodiesel (WP3-4) from fish-oil by-products showed little potential due to the high amount of chemical and energy required for extraction. In order to keep costs low and have added-value on the use of energy and resources, biogas production from these by-products are preferred (see WP2).
The project also proposed to look at the production of micro-algal biomass using waste-based growing medium. Even though it was possible to grow micro-algae using digestate from biogas production, the low micro-algal density did not show promising results for high volume production. Furthermore, the utilization of digestate into the growing medium might make the extraction of high-value micro-algal product not feasible.
Based on the results from this project the company RSI is developing further R&D work on the topic of biomethane production from fish waste into a new project called “Framleiðsla lífeldsneytis úr fiskúrgangi – Fjárhagsleg og tæknileg úttekt”. The testing method now commercially available has allowed the company to get international customers for testing their streams toward production of environmentally friendly biofuel. Icelandic companies can have access to specific services for biomethane production given them the opportunity to reduce their environmental impact and transform waste streams into revenue streams.
