Opportunity for increasing the anaerobic digestion of bio-waste in the perspective of the circular economy

Coordinated by: Francesco di Maria, University of Perugia (IT); Maria Cristina Lavagnolo, University of Padova (IT)

The EC indicated the anaerobic digestion (AD) as the most suitable process for the implementation of the circular economy in the treatment of the bio-waste. By the way, for several reasons, its implementation in this sector still remain quite limited. Nowadays the approaching to the end of the economic support period for many existing AD facilities exploiting biomasses could represent an important opportunity for increasing the use of AD in the bio-waste sector. In fact , there is a growing interest of the managers of these plants in finding alternative substrates, as the bio-waste, able to allow the viability of these facilities in the next future.
The goal is to discuss and give an informative description of the different technical, technological, economic, environmental aspect to be faced to grab this opportunity.
Furthermore, also other experiences related to other solutions, as the co-digestion of bio-waste with sludge, acidogenic fermentation of organics to produce renewable materials (e.g. bioplastics) could be presented and discuss.
The workshop context will contribute to deepen the knowledge about the roleof AD in sustainable development and circular economy.
