Hydrogen production from waste

THURSDAY 6 MAY 2021 / 10:00 - 13:00 (GMT+2)

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.


  • 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).

Aldo Muntoni is full professor of Environmental Engineering at the Department of Civil-Environmental Engineering and Architecture of the University of Cagliari, Italy, where he teaches the academic courses of Contaminated Sites Recovery and Remediation and of Soild Waste Management. He has been chairman of the PhD programs in Earth and Environmental Sciences and Technologies (EEST) and in Geoengineering and Environmental Technologies of the University of Cagliari. His main fields of interest are solid waste management, energy and material recovery from waste, hazardous waste stabilization, soil and sediment remediation. Author and co-author of more than 250 scientific papers published on international and national journals, international and national books, proceedings of international conferences. Reviewer for international journals. Responsible for several International and National research projects. He received awards, including the “National Energy Globe Award” in 2010 for research on combined production of hydrogen and methane from biodegradable waste.
