WHY THIS PROJECT Potential energy recoverable from wastewater
There is more energy in wastewater than is needed for treatment about 5X more But not only from wastewater. Energies recoverable from solar radiation, hydraulic power, gasification and incineration processes is considered

REEF 2W PROJECT
- REEF 2W project involves 5 countries (IT
, AT , DE, CZ, HR), 10 Partners and 3 associated partners
- REEF 2W was the only project of the call involving 5
private companies in the activities of the project
- Started in June 2017duration 36 month

SCOPE OF THE PROJECT
- To identify possible critical points for the energy efficiency of
the WWTPs
- Help to define strategies and technologies and evaluate possible
future scenarios for the waste treatment platforms integrating waste, wastewater and other renewable energy sources
- To provide an assessment on the excess of energy available and
where it can be delivered as electricity, heat, biofuel, biomethane to the nearby community to decrease its energetic impact.
- To provide a simple interactive TOOL able to help policy makers
and stakeholders to define the health state of the treatment plant and to identify possible improvements

SCOPE OF THE PROJECT
- To provide an environmental assessment of the actions
implemented
- To provide an economic assessment for the implementation of
different technologies
- Identify obstacles and barriers for the implementation of more
efficient system to recovery energy from organic wastes
- Involve local authorities to test the tool, and use it to contribute
at a better design of the energetic planning

PILOT SITES
- Technologies considered are
- Anaerobic digestion, biogas upgrading, power to gas, CHP
- Heat recovery from treated wastewater
- Gasification, Hydrothermal carbonization, composting,
incineration
- Photovoltaic, thermal and hybrids panels
- Hydroelectric power
- Others will be possible to implement in future (effects of
nutrients recovery, filtration technologies, wind, etc.)

INTEGRATED SUSTAINABILITY ASSESSMENT (ISA)
- ISA approach has been used to connect all the relevant aspects:
- Energy assessment
- Spatial assessment
- Environmental assessment
- Economic assessment
- Strong involvement of the user in collecting available data and
defining future credible scenarios

FURTHER ACTIONS
- Training courses for groups of Public Administrations and
Stakeholders have been delivered in the 5 countries to help them in the evaluation of possible opportunities to decrease the energy impact recovering energy from wastes
- Training courses will be conducted to train advisors
(Reef2w@gmail.com)
- Setting up of action plans at a regional levels to promote the use
- f REEF 2W approach in energy and waste planning and signature
- f MoUs with political authorities
- Book with the description of the experience developed in the
project
Involvement of Public Administrations and Stakeholders
