Asker, Norway, 24 July 2023
Cambi has been awarded a contract for two thermal hydrolysis process (THP)
systems to be integrated into the Moa Point wastewater treatment plant in
Wellington, New Zealand, as part of the new Sludge Minimisation Facility (SMF).
The project will revolutionise the way the city manages its wastewater solids.
THP will more than halve the required anaerobic digester volume, increase green
electricity production from biogas, and improve dewatering sufficiently to
reduce the size and energy requirement of the thermal drying facility by more
than 40%.
The Wellington City Council is committed to investing in innovative and
sustainable solutions for water and wastewater treatment. Apart from the
significantly improved energy balance, thermal hydrolysis will open safe avenues
for reuse to improve soil health or produce energy, reducing the volume taken to
the landfill by 80%. The new facility will reduce carbon emissions from solids
treatment and processing by more than 60%.
"Cambi is thrilled to enable the Wellington City Council to meet the target of
halving climate emissions by 2030 on the way to net zero. We look forward to
fruitful cooperation and the first thermal hydrolysis plant in the land of the
long white cloud", said Eirik Fadnes, Cambi CEO.
The Moa Point wastewater treatment plant services Wellington's more than 200,000
residents before discharge in the Cook Strait. The sludge minimisation project
is an essential step to improve the local environment and reduce carbon
emissions. The project is Cambi's southern- and easternmost yet.
HEB Construction and McConnell Dowell is the awarded contractor and will execute
the SMF project, with the thermal hydrolysis scheduled for operation by 2026.
