The project REEF 2W

The project REEF 2W faces the INTERREG CENTRAL EUROPE programme challenge of developing and implementing solutions for increasing energy efficiency and renewable energy production in public infrastructures, focusing on the municipal solid waste chain and the waste water treatment plants (WWTP).

The issue is addressed through a multiple approach:

  • by combining and integrating the relevant public infrastructures;
  • by upgrading their input mix and their energy outputs through the enrichment of the upstream supply chain providing compatibility with a wider biomass mix from agriculture, agro-food and public green biomasses;
  • by strengthening the integration and the empowerment of internal processes for maximizing the energy efficiency and the renewable energy outputs (electricity, heat, biogas, bio-methane, bio-products) as well as the sustainable closure of the organic waste cycle. In the considered scenario, the energy recovered from these biomasses will be mainly addressed for local use at WWTP, to feed public/private electric/heat/gas grids or used for the public mobility and waste collection trucks.

 

The project will show, through five pilot feasibility studies in different Central Europe regions, how the new REEF 2W approach could lead to an abatement of energy needs in many WWTPs and to a significant increase of renewable energy production, in the meantime decreasing the impact of organic waste disposal and excess sludge management from WWTPs.

Pilot cases become key enablers for WWTPs self-sustainable energy production, or even “positive renewable energy”, ideal for describing new scenarios for self-production of green energy to be applied in the next coming smart-cities.

Costs decrease or induced profits can be reinvested in improving urban services or in renewing the WWTPs themselves. This last result can help also to solve a problem affecting many old WWTPs, relying on the need to fulfil new stringent environmental regulations, with consequent negative increase of operating costs and energy unbalance. The project, with a transnational approach, will make available for all public administrators and stakeholders knowledge, information about REEF 2W solutions, set up the criteria to identify suitable REEF 2W sites, provide tools for feasibility studies, perform feasibility studies, start the design of new REEF 2W plants, identify and help to remove barriers/obstacles that can hinder REEF 2W realizations in the programme area, where more than 20.000 WWTPs are operating.
