Circular economy How do Interreg 2 Seas projects contribute to increase the adoption of new circular economy solutions in the 2 Seas area.


The NEREUS project seeks to establish wastewater as a valuable source of water, nutrients and energy. The partnership will install nine wastewater plants to pilot relevant technologies and will subsequently develop strategies and tools to support implementation on a large scale.

Many of these pilot sites are close to being fully operational. For example, CAPSO has found a way to optimise sludge treatment, resulting in dried sludge that can be reused on local farmlands.


The Horti-BlueC project’s goal is to increase the adoption of circular economy solutions through the sustainable up-cycling of agri-food and fishery by-products in horticulture. By optimising waste pre-treatment and processing, they aim to prove the feasibility of four valorisation chains for producing innovative materials for soil-less cultivation through pilots and collaborative platforms.

This will save resources, drastically reduce CO2 emissions and limit the use of chemical pesticide and fertiliser within greenhouse horticulture.
