Starlinger has a nose for low-odour recycling
‘A bad smell in recycled materials may be generated by impurities, which also greatly reduces the possibilities for its further use,’ Starlinger notes. Its recycling technology, presented at the recent K-2016 trade show in Germany, significantly reduces nasty odours during and after recycling.
Visitors were able to test this personally at the firm’s so-called ‘smelling table’ by sampling treated and untreated materials. Starlinger’s method works without the use of additives, achieving ‘excellent resin quality’ with improved smell on a permanent basis.
The odour-reduction process consists of three steps: material preparation in a SMART feeder where the material is heated and homogenised until the ideal operation point is reached; a C-VAC degassing module with 300% increased melt surface for the highest possible degassing efficiency; and a Smell Extraction Unit.
The permanently odour-improved regranulate is ‘of the highest quality’ and can be used in a wide range of applications, Starlinger insists. The manufacturer reports that the first line equipped with the new odour-reduction technology has already been sold and will be installed and commissioned within the next few months.
‘Odour is a burning issue for a lot of plastic recyclers,’ says Paul Niedl, head of sales for recycling technology at Starlinger. ‘Many visitors came to our booth (at K-2016) specifically to request information on our odour-reduction process because they have to deal with this problem and had heard about our solution in the run-up to the exhibition.’
