SUEZ invests in Airex Energy and Subeca, specialized in decarbonation and WaterTech

SUEZ, a world leader in circular and digital solutions for water and waste, announced its acquisition of stakes in the innovative North American companies Airex Energy and Subeca, amounting to 8 million euros.

These two investments in support of climate change adaptation and mitigation reinforce SUEZ’ innovation dynamic. They fall within the Group’s open innovation policy.

SUEZ reasserts its stance in carbon sequestration through the acquisition of a stake in a Canadian company

In July 2023, SUEZ, Airex Energy and Groupe Rémabec announced the creation of the joint venture Carbonity to build Canada’s first biochar plant in Port-Cartier (Quebec). Produced from forestry and agriculture biomass, biochar offers several benefits: carbon sequestration, increased nutrient retention, optimized water availability and soil aeration. It was identified by the Intergovernmental Panel on Climate Change (IPCC) as one of the five most efficient negative-emission solutions.

SUEZ’ arrival as shareholder of Quebec-based Airex Energy illustrates the two firms’ desire to take their collaboration further, and additionally ties in with the low-carbon goals set out in SUEZ’sustainable development roadmap. Capitalising on Airex Energy’s technology, the two companies intend to develop annual production capacity of more than 350,000 tonnes of global biochar from hitherto insufficiently or unexploited agricultural and forest biomass resources. This collaboration also aligns with the 2050 net zero target qualified as indispensable at COP 28.

SUEZ invests in WaterTech in the United States

Based in Dallas, Texas, Subeca is an Internet of Things (IoT) specialist that develops smart water metering solutions compatible with Amazon Sidewalk, a free-to-connect communication network for IoT that covers more than 90% of the American population. Advanced metering infrastructure (AMI) is an essential tool to help reduce water consumption and preserve resources, cutting volumes by up to 16% thanks to leak detection and use monitoring. Subeca’s IoT solution makes for the simple and cost-efficient deployment of this water metering. In the US, it could enable more than 40,000 water utilities and private companies currently locked out of advanced metering to gain access to remote water meter reading and monitor their consumption effectively.
