Elkem scales up silicone upcycling
Silicones maker Elkem has announced that technical implementation of its chemical recycling project for silicone waste at its facility at Saint-Fons near Lyon is now being carried out at pilot scale . This uses a patented depolymerisation featuring low process temperatures ,
lower carbon emissions , high conversion rates and chemical selectivity to recover raw materials from waste for reuse in making new silicones .
“ The pilot unit will provide vital scale-up information for safe and energy-efficient recycling of silicones at the industrial scale , and supply Elkem ’ s target customers with representative quantities of silicone with recycled content ,” Elkem said .
The Resourcing Silicones Polymers ( REPOS ) project , as it is known , project began in 2021 . It was developed in partnership with CP2M and IMP academic labs , and the SMEs Activation and Processium . Funding came from the France 2030 national innovation and industry investment programme and the EU ’ s NextGenerationEU fund .
Subsequently , Elkem secured € 1.8 million in EU funding for its Elkem Sicalo ( Silicon production with carbon looping ) project at its site in Kristiansand , Norway . Sicalo aims to capture the carbon emitted from the furnace and reuse it as a reductant in the silicon production process . A pilot plant is now being completed .
