With the transition to the virtual event we have the chance to accept further proposals for presentation and to introduce additional topics to be explored and discussed at the Venice Symposium 2020, as detailed below. Late abstracts can still be submitted through the online submission form.
• LOW TEMPERATURE CONVERSION PROCESSES
The valorisation of biomass as a fuel source can be limited by some unfavourable properties (low heating value, high moisture, low energy density, etc.). These properties can affect transportation and handling costs, storage, combustion quality. Low-temperature thermal treatments can modify these properties supporting the energy valorisation.
• SOURCE SEPARATION OF MSW
Source separation has important effects of waste-to-energy options: food waste selective collection can support an efficent biogas generation through anaerobic digestion; residual MSW can result in a higher LHV. Transient scenarios of source separation must be managed carefully in order to avoid mismanagement.
• SITING OF PLANTS
Both for biomass to energy and for waste to energy, the siting issue is one of the main problems to face; aspects of economic sustainability, social acceptance and environmental compatibility must be taken into account through an integrated approach that, today, can take advantage of a remarkable evolution of scientific methodologies and tools.
• SMALL THERMOCHEMICAL WASTE TREATMENT PLANTS
Decentralisation is an option of growing interest in the sector of special waste. In some cases the quali-quantitative characteristics of the generated waste and the simplification of the authorisation pathway make interesting the adoption of processes suitable for small plants.
• WASTE TO ENERGY AND CIRCULAR ECONOMY
Circular economy is clearly oriented to material valorisation. However, waste to energy can still play an integrated role, both in terms of biogas generation and energy valorisation of non-recyclable waste.
• DIGITALIZATION AND AUTOMATION
Digitalization and automation are more and more present in the technological sectors. Their potentialities in supporting biomass and waste to energy options must be taken into account for the success of a project.
• INTEGRATED ENERGY SYSTEMS
The concept of integrated energy systems refers to the implementation of strategies based on synergies allowed by the energy sector characteristics. Various energy fuels and carriers are available together with end-users belonging to sectors where carbon consumption and related emissions must be reduced. An efficient integration can avoid energy losses and waste.
• ENERGY VALORISATION OF SEWAGE SLUDGE AND P REMOVAL FROM ASHES
Final treatments of sewage sludge can be based on specific energy recovery strategies. This scenario can be enriched by material recovery strategies: the recovery of Phosphorus from ashes is growing of interest taking into account the availability of natural reserves and the environmental impact of mine activities.
