Building and protecting
the planet's future

Cambi's greatest environmental impact comes from the emission reductions our technology enables in wastewater solids treatment.

• Our thermal hydrolysis process (THP) enhances biogas production, reducing reliance on fossil fuels. Additionally, it reduces the overall volume of sludge, which in turn minimises transport emissions and decreases the need for energy-intensive disposal methods such as drying or incineration. In some projects, THP also replaces new digester tanks, which typically have much higher embodied carbon.

• By transforming wastewater solids, stone meal, and garden waste into peat-free soil products, Grønn Vekst provides an alternative to peat extraction, a significant source of carbon emissions. Shifting to sustainable soil products helps preserve natural carbon sinks, while also reducing the emissions associated with synthetic fertiliser production.
• Cambi's carbon impact extends across the entire sludge management cycle – from treatment to energy recovery and final reuse. Hence, a detailed carbon accounting of this positive impact is complex due to varied operational conditions in numerous countries and many interdependent factors. Cambi is exploring ways of better quantifying this impact while improving its own sustainability performance.

Cambi's solutions enable the recovery and reuse of valuable resources from wastewater, contributing to the circular economy.

• Our thermal hydrolysis process (THP) transforms wastewater solids into safe, high-quality biosolids, which can, in some places, be reused in agriculture as organic fertilisers, reducing the need for synthetic alternatives while enhancing soil health.

• Beyond wastewater treatment, Grønn Vekst transforms treated biosolids and garden waste into peat-free soil products, reducing landfill dependence and promoting sustainable land use.

As global challenges around climate change, resource scarcity, and circular economy adoption grow, we seek innovative ways to enable wastewater utilities and industries reduce emissions, optimise energy use, and recover valuable resources.

• We continuously enhance our modular THP systems to improve energy efficiency, operational resilience, and system adaptability.
• By integrating digital monitoring, automation, and process optimisation, we help operators improve plant performance, reduce downtime, and lower operating costs.
• Our subsidiary, Grønn Vekst is developing sustainable alternatives to peat-based soil products based on compost, stonemeal and other ingredients.
• Cambi actively partners with research institutions, universities, technology providers, and industry leaders to develop next-generation solutions for wastewater and biosolids management.
• Our participation in research programs, pilot projects, and industry initiatives enables us to test and scale new approaches for emissions reduction, energy efficiency, and nutrient recovery.
