PETpla.net Insider 01+02 / 2010

PET bottle-to-bottle recycling plants After more than 100 market surveys it is now time to turn our attention to machinery used in bottle to bottle recycling. We have for a long time been deliberating on whether to explain the technique used to transform used bottles into new bottles to you. We have decided not to bother. Because, at the end of the day, you are only interested in one thing and that is what goes in (material, energy, water) and what comes out (granulate with approval). As is so often the case in practice, something that sounds very simple to start with may turn out in the end to be not quite so easy after all. Ultimately, the input variable “Material“ is, to a major extent, dependent on the local circumstances. Systems ranging in size from 5 - 40,000t/a are particularly suitable for on-site installation, and depending on the local collec- tion systems, the input variable “Material“can be highly differentiated. However, in order to make the systems comparable, we have opted by way of input variable for materials that are freely traded. When it comes to bottles it is almost a worst-case sce- nario - unsorted bottles in all colours and pressed into bales, whereas with the flakes it is a matter of slightly higher quality wares, clear with only a few contaminants. Whilst PETplanet Insider has have made every effort to ensure that the information in this new survey is up to date no claims are made regarding completeness or accuracy. All data is as supplied by the manufacturers. 01+02/10 MARKET survey  PET bottle-to-bottle recycling plants Caps and closures Conveyers for preforms and empty bottles Preforms Preform moulds and SBM moulds 2-stage SBM machinery Preform and single stage machinery Resins and additives Filling equipment Compressors Company name Erema Engineering Recycling Maschinen und Anlagen GmbH Postal address Telephone number Web site address Contact name Function Direct telephone number Fax E-Mail Unterfeldstr. 3 A-4052 Ansfelden, Austria www.erema.at Christoph Wöss Vacurema Product Manager +43 732 3190-352 +43 732 3190-23 ch.woess@erema.at Bottle to Granulate cooporation with different wash plant manufacturers Input variable: collected pressed bottles, various colours Output: Granulate with approval Capacity [t/a] Floor space [m²] Which approvals Fresh water consumption per tonne output [m³/t] Consumption kWh per tonne output [kWh/t] Flakes to Granulate Vacurema - 3 models: Basic, Advanced, Prime Input variable: Flakes, coloured proportion max 5%, not much chlorine Basic flakes specification see below - Principle: Higher contamination levels are basically possible to process, after discussion and agreed by Erema, but could influence the quality of the pellet.
