Asker, Norway, 28 January 2024 

Cambi has signed a major contract to supply a thermal hydrolysis process (THP)
system to the City and County of Honolulu's Department of Environmental Services
at the Honouliuli wastewater treatment plant. 

Honouliuli is Oahu's second-largest wastewater treatment plant with a design
capacity to process 51 million gallons, or 193,000 m3 of wastewater per day. The
plant has been modernized with a secondary treatment step before deep ocean
outfall and is now investing in modern thermal hydrolysis solids treatment
before anaerobic digestion. 

Thermal hydrolysis from Cambi will increase solids processing capacity for the
existing digesters and accommodate the increasing solids volumes arising from
the introduction of secondary treatment without the need to build two new
digesters. The THP will also significantly increase biogas production and
produce dryer biosolids providing volume reduction.  

"Cambi is proud to be entrusted with this important project to improve the
economics and environmental footprint of solids treatment in Oahu. We look
forward to a fruitful cooperation with main contractor Hensel Phelps and the
Department of Environmental Services in the coming years, to bring thermal
hydrolysis to Hawaii on time and budget," said Cambi acting CEO Lars-Petter
Traa. 

The project is Cambi's 12th in the US. The THP system will be delivered to site
in 2026, with operations scheduled to start in 2027.
