Degrés bleus is an innovation from Lyonnaise des Eaux, subsidiary of SUEZ ENVIRONNEMENT, which allows them to recover the heat from wastewater to heat buildings, a renewable energy that hadn't been used until now. This technological…
Turn end of life plastic (ELP) into diesel, it is possible! SITA UK, subsidiary of SUEZ ENVIRONNEMENT, and Cynar Plc are building, until end of 2011, first operating plants in Great Britain to convert the plastic end of life into diesel…

The research and innovation (R&I) carried out at SUEZ ENVIRONNEMENT is structured around several governance bodies. These bodies aim to propose, identify, finance and monitor research projects on a long- or short-term basis.
SUEZ ENVIRONNEMENT has restructured the governance of its R&I programs around 3 areas:
The Group also has an innovation investment fund: Blue Orange. This fund supports the commercial and industrial development of young companies that create innovative technology in the environmental services sector. With a budget of €50 million over 10 years, Blue Orange positions itself as an investor and industrial partner.
At the same time, SUEZ ENVIRONNEMENT has launched Innovation Task Force, a system to govern and steer innovation. It identifies innovative projects that could be accelerated by financing technological tests and industrial pilot projects. Over 20 projects have already been launched.
SUEZ ENVIRONNEMENT is making a difference by continuously offering innovative solutions to its customers. The Group helps customers reconcile economic performance with environmental performance by ensuring:
The Group is helping establish a new development model focused on operations inspired by natural cycles. Its proposed solutions intervene in the great water cycle to protect water quantity and quality. These solutions also protect biodiversity through specific programmes such as the tailored management of industrial sites.
With the innovative Degrés Bleus, Lyonnaise des Eaux supplies all or part of the energy a building consumes for heating and air-conditioning by recovering heat from the wastewater treatment network. By using a heat pump the system is reversible: it can provide hot air during the winter and cool air during the summer. This is the case, for example, at the Levallois-Perret Aquatic Center, one of the first buildings to be fitted with such a system.
Optimal temperature from wastewater heat
SITA France and the Paprec Group, two of the leading recycling companies in France, have joined forces to create a unique site for processing sorted plastic bottles to produce other food-grade bottles.
SITA UK and its partner Cynar Plc give plastic a new lease on life, limiting the amount of waste sent to landfills by recycling some of the bottles into fuel.
