DECISIVE A DECentralised management Scheme for Innovative Valorisation of urban biowastE – aims to help with the reform of urban waste management systems for our ever-growing cities and populations. 

Project co-funded by the European Commission, under the Horizon 2020 programme.


The thirteen DECISIVE partners have met in Hamburg from 17 till 19 October 2017 for the project’s 3rd General Assembly.

Hosted by the Hamburg University of Technology, the meeting was an excellent opportunity to look into recent project developments, namely the micro-AD and SSR process specifications and the decision-support tool.

Additionally, the two pilot implementations were extensively discussed. These sites will demonstrate the feasibility and benefits of decentralised bio-waste handling systems in two different contexts:

  • In Lyon the plant will be implemented close to the Refarmer urban farm. It will treat about 50 tonnes per year of bio-waste collected in restaurants. This site will highlight potential synergies between urban farms and the DECISIVE system;
  • In Catalonia the unit will be implemented on a university campus, treating about 200 tonnes per year of bio-waste from both inhabitants and collective catering.

More details are available on the DECISIVE project's website.



 This project will look to alter the current urban metabolism for organic matter, energy and biowaste, to a more circular economic model and to assess the impacts of these changes on the whole waste management cycle.

The project will thus contribute to change the management of urban organic material fluxes from a linear paradigm (import of goods without thoughtful interaction between external, peri- and intra-urban area, consumption, external disposal of waste) to a circular paradigm. It will help moving waste management towards a "Zero-Waste" strategy and to achieve the objectives of the European Resource Efficiency Roadmap.




The objective of the DECISIVE project is to demonstrate the ability to decrease the generation of urban waste (from household or assimilated) and increase recycling and recovery by focusing efforts on decentralised management and valorisation of the organic fraction of waste, i.e. biowaste, in a short cycle.
