Periodic Reporting for period 2 - DECISIVE (A DECentralIzed management Scheme for Innovative Valorization of urban biowastE)
Reporting period: 2018-03-01 to 2019-08-31
• Assessment of the DECISIVE concept sustainability
The work on the concept assessment progressed a lot especially with the design of life cycle inventories, the decision of sustainability indicators to be included in the DST and a network analysis achievement. Moreover a numerical method to plan the spatial organisation of the decentralised treatment network on an urban area has been developed. It uses conjointly geographical inventories of biowaste production, urban and peri-urban farms, etc. and a mixed integer linear program for optimisation.
• DST development
A first version of the DST has been developed and delivered to be used freely through a web-interface. This DST is now being tested to assess the decentralised management applicability to 10 cities in Europe. Moreover feedback is expected from users outside of the DECISIVE consortium.
• Processes development
Process development knew a real progress during this period with the design of pilots for both the new dry mAD process and the SSF process. First performance results have been obtained and delivered and the processes will continue to be tested and improved up to the end of the project.
• Demonstration site preparation
During period P2 the project really entered the demonstration step with the concrete organization on the chosen sites. The implementation of a mAD demonstration on the site initially forecasted in Catalonia had to be abandoned (difficulties with University) and the final real demonstration sites for the project have been confirmed as follows: the LYON demonstration site in France and the DOLINA demonstration site in Italy. In the first case, the demonstration has already been implemented by setting up AD pilot on the Lyon urban farm exploited by reFARMERS in the close surrounding of Lyon. The demonstration is now starting. In the second case, AD device has been chosen and will be set up by mid-2020 in the urban area of Dolina. This area is located far from centralized waste management facilities and its waste management is led by A&T2000, who will operate the demonstration. In addition to these two real demonstration sites, and in order to benefit from the work developed in Catalonia by ARC to study the possibilities to implement a demonstration on the UAB Campus (near Barcelona), it has been decided to test there the waste prevention effect due to the implementation of a decentralised treatment (community composting) and linked communication. Finally, a test study of new collection system will be performed in Lübeck by TUHH.
• Data collection for the assessment of the concept benefits and impacts
Data collection is on-going and exchanges among partners and especially on the demonstration sites are planned for the following months in order to gather technical, environmental, economic and social data to complete LCI and assessment databases.
