This study investigates biowaste valorization’s (BV) sustainability implications based on the Sustainable Development Goals (SDGs) interaction analysis using a mixed-methods approach. Firstly, the authors synthesise current scientific knowledge through a literature-based analysis. Secondly, they investigate insights on BV-SDG interactions at a national context: the authors elicit stakeholder views through semi-structured interviews in Greece as a national case application.

The valorisation of urban biowaste can contribute to a circular and sustainable resource management. However, biowaste valorisation is not inherently sustainable. This study employs the Sustainable Development Goals (SDGs) to investigate the sustainability implications of biowaste valorisation. A narrative literature review provided an overview of the current scientific knowledge on interactions between biowaste valorisation and selected SDG targets. Then stakeholder interviews yielded insights into such interactions in a national context. The authors’ findings show the potential for 19 synergies and 11 trade-offs between biowaste valorisation and 20 selected SDG targets that are addressed in detail. Although the synergies outnumber the trade-offs, different context-dependencies influence the nature and strength of the interactions. The authors highlight three types of context-dependencies relating to governance. This study informs the scientific community and decision-makers on planning for sustainable biowaste valorisation that addresses context-dependencies. The insights can guide countries and cities at early transition stages towards biowaste valorisation.
Project / Urban waste into circular economy benefits (UrbanCircle) is developing a way to integrate waste management and resource recovery into a circular economy.
Project / Regions4Climate will implement innovative actions to enhance climate resilience within the real-life environments of partner regions.
Past event / This event will focus on how to incorporate the circular economy principles and criteria on the strategic level in local municipalities.
Project / Together with UNCDF and ICLD, SEI is empowering African municipalities to access climate finance and build resilient communities.
