The manufacturer of single-screw extrusion equipment and screen changers, among other equipment, claims it is the first extruder manufacturer to receive an unrestricted Non Objection Letter from the U.S. Food & Drug Administration (FDA) for its complete PET recycling system. The company already in 2010 received a Non Objection Letter from the FDA for a complete PET recycling system including a solid state polymerization (SSP) system.
Now, Gneuß (Bad Oeynhausen, Germany and Matthews, NC) has received an unrestricted Non Objection Letter (NOL) for food packaging products of all types (classes C - G) for its extrusion process. This means users of the system can do without any treatment of PET before or after extrusion.
Explains managing director Stephan Gneuss, "The FDA Non Objection Letter for the processing of up to 100 % PET bottle flakes only using an extruder - without any pre- or post- extrusion treatment of the material - is a unique selling point." The manufacturer says it has sold more than 20 of these extruders since the market launch in late 2007....
