| Using innovative chemical processes, we can recover materials contained in industrial baths, effluents, sludge and components. Today, we can recycle metals, solvents, hydrocarbons and soiled packaging under economically viable conditions.
In France, we recycle fluorescent tubes at end-of-life. After specific treatment, the various components are reused as secondary raw materials: aluminum, fluorescent powders, iron and glass. We have processed more than 2 million tubes (450 metric tons) and have established a collection service from electricians, using a specific recovery kit.
Saline and alkaline batteries are treated using a new process that extracts the solid metals and plastics, and zinc and manganese oxides. Once dissolved, these materials are extracted and recovered. For the BRGM (French Geological Survey) and Antéa, we have developed a process to recover phenol-laden spent foundry sand. In Chaingy, we grind the sand, remove the ferrous and non-ferrous content and mix it with bacteria that feed off the phenol. It can then be reused in road base layers or as backfill.
The CREED research center is testing and developing a solution to incorporate in concrete the glass recovered from TV cathode ray tubes. In partnership with manufacturers, it is also involved in research on the dismantling and recycling of plasma screens. In conjunction with the University of Metz, CREED has patented a process for the selective recovery of two metals in the industrial wastewater from a chemicals plant. Recovered in the form of a 95-97% pure hydroxide, it is then sold to a metallurgical company
In Hong Kong, MARPOL waste from ocean-going vessels is delivered to the Enviropace site. There, we treat and process it into a refuse-derived fuel. In the United Kingdom, we provide services to cruise liners, merchant ships and aircraft carriers berthing in the Solent, for which we use a 176-ton ship: the Douglas McWilliam. It pumps out the slops and collects all types of waste: general on-board waste, medical, scrap metal, lead batteries and hydrocarbon liquid waste. It then ferries its load to our Marchwood center. Liquid sludge is heated to 100°C to collect the oil that is then sold. |
