CHICAGO — Sorema Plastics Recycling Systems of Como, Italy, has designed a modular recycling system, giving companies the ability to add equipment as business expands.
In a June 17 interview at NPE 1997 in Chicago, Sorema President Aldo Previero said the system allows customers to start conservatively, then grow with added business and new application niches.
``Beginners have less capital at the beginning, which grows with experience,'' Previero said.
The 21-year-old firm began supplying PET recycling equipment consistently about nine years ago. It now has more than 200 recycling lines in operation around the world.
Sorema's recycling process can be broken down into several steps: bottle and film prewashing, wet and dry grinding, storage, hot washing of flakes, multistage washing centrifuges, rinsing centrifuges, separation tanks, mechanical drying, hot drying, extrusion and materials handling. The equipment needed for each step can be integrated with the other recycling machinery.
``We recommend the needed equipment around our design and [to] target specific contamination [in the recycling stream],'' Previero added. ``Then we implement the next process for finer quality when it is needed.''
Sorema's modular concept can recycle PET, high density polyethylene, PVC and polystyrene.
Replastic, which claims to be the largest Italian organization for recycling, has used this system for a year. It processes as much as 6,000 pounds of PET per hour, according to Previero.
He said Sorema also has sold the equipment to a large fiber manufacturer in Italy.
