NTNU Oceans and NTNU Sustainability have established a joint initiative titled NTNU Action Ocean Plastic Waste, currently for the 3-year period 2020-2022. The purpose of the initiative is to contribute to NTNU's vision 'Knowledge for a better world', more specifically with activities for increased knowledge in the area of plastic waste, marine plastic littering and plastic pollution, in line with UN SDG No. 14 and its targets.

The EU-funded ATLANTIS project will develop a model for quantifying impacts on ecosystem service losses, as well as impacts of marine plastic debris and of marine invasive species within the life cycle assessment framework. The findings will help ensure sustainable marine ecosystem management.

Blue Circular Economy (BCE) is a three-year (2018-2021), transnational project co-funded by the EU Interreg Northern Periphery and Arctic Programme (NPA). Its aim is to support the development of the fishing net waste industry in regions across Europe’s Northern Edge. This project builds on the previous project called Circular Ocean(2015 – 2018). Blue Circular Economy (BCE) aims to help small and medium-sized enterprises (SMEs) offering products and services within fishing gear recycling solutions in the NPA region to attain a greater market reach.

The objective of the GoJelly project is to use jellyfish as source of innovative solutions to combat marine litter, in particular microplastic pollution. It aims at  developing a microplastics filter for commercial and public use, where the main raw material is jellyfish mucus. In doing so, it addresses the problems of both jellyfish and microplastics, ultimately leading to less plastic in the ocean, a demand for jellyfish raw material, and more jobs for commercial fishermen in off-seasons.

The pilot study is a multidisciplinary research activity where researchers and doctor students collaborate to cope with the complex societal interactions in changing coastal communities. It is initiated by NTNU Oceans, aiming at establishing a deeper knowledge base of the dynamic interplay between education, identity, society and industry across generations in coastal communities.
