I am an environmental engineer working for the transition towards circular economy. While current production and consumption models face increasing environmental, social and economic challenges, re-designing the economic and technical systems promises steady steps to a more sustainable future.

My PhD project is a part of the EU H2020 research project DECISIVE (Decentralised management scheme for innovative valorisation of urban biowaste) which explores decentralised bio-waste management strategies. This PhD research focuses on the development of circular bio-economy alternatives for local management systems while it assesses their environmental benefits and backsides. Moreover, complementary and alternative ways to promote citizens' awareness and communication practices are investigated by exploring the roles of eco-industrial networks in the transition process.


The aim of the PhD is to assess benefits and drawbacks of the transition from linear, large scale to circular, decentralised biowaste management systems.


The first paper provide o proof-of-concept for the DECISIVE DST, a decision support tool based on lifecycle assessment, by comparing the enviromnental results with a lifecycle assessment performed in SimaPro. The second paper is a systemic review supported by statistical analysis of the results that compares the biowaste quality deriving from different collection schemes. The third paper explores the relationship between economic feasibility and environmental performance of different scale biowaste treatment methods, e.g., anaerobic digestion. The fourth paper maps the transition from small scale to large scale anaerobic digestion and solid state fermentation, in the form of a lifecycle assessment.
