Citisystem

Biobased material constitutes one of the largest waste streams in European cities, and a central concern is how to use these streams in a circular way.

According to the waste hierarchy, after prevention, the preferred options are reuse, recycling and use as an energy source. However, disposal still occurs. Biowaste’s potential in contributing to circularity is notable, because it provides valuable soil-improving materials, fertilisers and biogas. With a share of 34%, biowaste is the single largest component of municipal waste in the EU. The recycling of this biowaste is key to achieving the EU’s goal of recycling 65% of municipal waste by 2035.

Objectives

The aim of the CITISYSTEM project is to support cities in promoting the biobased circular economy by increasing specific actions in urban areas and involving the community in learning about the nutrient and energy flows of their closest environment.

To achieve this main objective, CITISYSTEM proposes focusing change at both the community and system level. The idea is to carry out the following actions:

• Create circular economy solutions, such as organising the selective collection of biowaste, supporting the innovative use of biowaste in products and supporting the biogas and compost production process to promote local energy and nutrient loops.
• Increase awareness and understanding among communities and stakeholders of the importance of the regional biobased circular economy, that is, one that makes full use of regional resources.
