HBI's Urban Circular Biorefinery
Sustainable innovation for the sewage sludge treatment
Driving partner for change
HBI is an Italian high-innovation company and the creator of the Urban Circular Biorefinery model — the new frontier of wastewater treatment — where sewage sludge is transformed into valuable resources, renewable energy, and water. In this model, the treatment plant becomes a true pillar of the European circular economy.
Since 2016, we have been developing solutions that integrate engineering and research, transforming wastewater treatment plants into strategic water and energy reserves serving local communities and the circular economy — systems capable of recovering water, renewable energy, and critical raw materials such as phosphorus.
