Cadbury owner Kraft and Swiss confectionery giant Nestlé have joined a consortium backing Enval, a technology company that has developed a system to separate and reprocess aluminium and plastic laminates. Enval opened a test site in Luton last year to demonstrate the ability of its technology to extract the aluminium from multi-layer formats such as aseptic cartons, pouches and toothpaste tubes. The Cambridge University spin-off firm is now planning to build its first commercial-scale plant and is expecting to open the facility in early 2012. Enval’s process extracts aluminium from laminate materials for recycling, and uses microwaves to turn plastics and other non-aluminium materials into pyrolysis gas that can be used in generating electricity. David Boorman, Enval business development director, told Packaging News that talks were underway over the exact location of the facility. He said that the business was also in talks with other “tier one” brand owners over funding the facility. Kraft Foods senior director for packaging research, development and quality Perfecto Perales said: “We’re hopeful the Enval Consortium will build on our past successes with other groups that proved effective in driving the collection and re-use of post-consumer flexible packaging waste.” Boorman added: “The primary purpose of the consortium is to share the capital cost of building the first Enval commercial plant and drive awareness of the technology to accelerate its adoption. “Enval’s focus now is on constructing the new plant so that it is ready for commissioning early next year and then commencing commercial operations soon after that.” Financial details of Kraft and Nestlé’s involvement in the consortium have been kept confidential.
