Within the context of its proactive innovation policy, SUEZ’s strategy is keeping with a partnership approach with third-party companies through “Innovation Technological Tests”.
Regardless of whether provided by partners who are start-ups, large groups, or small to medium enterprises, these tests enable innovative solutions to be tested under industrial conditions. This approach has the advantage of being able to considerably accelerate time to market and therefore to market new technological solutions meeting out clients’ needs. Representing an overall financial commitment of nearly 5 million Euros per year, these tests co-funded by the Group have already given rise to 26 achievements since they started at the end of 2010. They tend to generate offers in a minimum amount of time and result in commercial partnerships.
A genuine revolution on the collection market, the 100% electric refuse truck is the result of work between SITA PVI, the leader in electric vehicle traction, Dow Kokam, a lithium/ion battery manufacturer and SEMAT, specialists in collection and waste management equipment. Besides being silent, each truck avoids the emission of 1300 tonnes of CO2 per year, has an autonomy of 18 hours and can collect up to 16 tonnes of waste in two rounds. The vehicle enjoys excellent manoevrability, and a totally panoramic view from the driving seat, which allows it to fit in easily with the urban environment whilst maximising safety.
The 100% electric refuse collection vehicle in service in Courbevoie (France) since 2011, precisely meets the local authorities requirements by improving the life of local residents.
In an economy where raw materials ares becoming scarce and the use of renewable energy is encouraged, sludge represents a resource which can be used because once treated, it can become a valuable product containing water, organic matter and minerals. Inspired by the industrial production of fruit juice, Degrémont, an operations company within SUEZ, developed an innovative, efficient and economical treatment solution for sludge in partnership with Bucher Unpektin. Using the Group’s experience in Switzerland, this sludge dewatering technology enables a higher dry content in sludge to be achieved than that obtained by so-called traditional methods such a centrifuge or filter press and without having to add lime. Sludge dewatering before drying enables significant energy savings to be made and allows up to 20% more room to be saved compared to a filter press. Therefore, this sludge can be recovered in landfills (used in caps) or in cement kilns as well as the current outlets for land spreading and composting.
From Open source data, Aqualogy developed InMap, a tablet-based GIS application for field operation. This tool is based on a geographic viewer and provides the operator with a mobile GIS enriched with external spatial data (Google Maps), and even third-party data. InMap has already been deployed in Aïgues de Barcelona.
