18th INTERNATIONAL SYMPOSIUM ON WASTE MANAGEMENT
AND SUSTAINABLE LANDFILLING / 11-15 OCTOBER 2021

Hydrogen production from waste

THURSDAY 6 MAY 2021 / 10:00 - 13:00 (GMT+2)
Luca Alibardi, Cranfield University (UK)
Aldo Muntoni
, University of Cagliari (IT)





Hydrogen has often been considered a chimera in the energy sector, a promising solution with potential benefits but difficult to be implemented. Now the situation is different. The strong commitments from nations and organisations to reduce carbon emissions and the momentum from the public opinion in asking for real changes towards a low carbon and circular society are highlighting how hydrogen can solve a number of challenges that electrification alone would struggle to deliver.
Sustainable hydrogen can be extracted from water, sludge and waste via a variety of electrochemical (water electrolysis), thermo-chemical (e.g. gasification, wet oxidation) and biological (e.g. biophotolysis, photo-fermentation, dark fermentation, microbial electrolysis cells) processes. Some of them are applicable in waste management schemes and can create innovative treatment systems that can create value recovery chains from waste.

The webinar will provide an understanding of the role of hydrogen to support a low carbon society and an overview of the status of the technologies for hydrogen production from waste. Webinar will be beneficial for professionals working in the waste and wastewater management sectors willing to explore hydrogen possibilities and links with carbon emissions reduction.

TOPICS FOR THE WEBINAR:

  • Hydrogen for a low carbon society
  • Hydrogen production processes for waste management
    - Thermochemical processes
    - Biological and bio-electrochemical processes
  • Dark fermentation and the biorefinery concept


 


Dr Alibardi is Lecturer in Separation Processes at the Water Science Institute of Cranfield University (UK). He holds a degree and a PhD in Environmental Engineering from the University of Padova (IT). Dr Alibardi’s research interests centre on the development of separation technologies and systems integration to lead on the transition towards the circular and hydrogen economies. He is active in the definition of the role of hydrogen to decarbonise the wastewater sector and on the development of the concept of biorefinery for the waste management sector. He works the area of energy recovery systems from wastewater network to understand the wider impact of these systems and on the use of coarse separation systems as an alternative to conventional membranes to develop combined membrane-biological processes to sustain the production of added value products from waste materials.

Dr Alibardi is Centre Manager of the EPSRC Centre for Doctoral Training in Water Infrastructure and Resilience (WIRe - www.cdtwire.com). He is also Co-Leader of the Task Group on Waste Biorefinery of the International Waste Working Group (IWWG - www.iwwg.eu).
