When Closed Loop London began producing food contact grade HDPE from transparent bottle material back in 2008, the company turned to B+B Anlagenbau GmbH and Erema Engineering Recycling Maschinen und Anlagen GmbH for support in meeting the technical requirements this involved. Due to increased demand for recycled material from major brand owners, it was not long before more capacity was needed. Closed Loop London decided to expand its existing plant capacity to 4,800 kg/h in total, and once again called in the services of B+B Anlagenbau and EREMA
Closed Loop is a recycling company headquartered in Australia with more than 10 years experience in providing comprehensive environmental solutions across industries including aviation, hospitality and health. Located in Melbourne, Sydney, London and Hong Kong, Closed Loop is the first in the world to recycle both PET and HDPE plastic bottles into food grade material for new food and drink packaging. The new expansion line in this case was for the production of food grade recycled HDPE from HDPE milk bottles, a process involving "dry cleaning," air classification, hot wash, sink float separation, mechanical drying from B+B and subsequent extrusion with upstream decontamination from EREMA.
