Using recycled PET (in short R-PET) for packaging production reduces energy consumption and CO2 emissions.
Climate protection is a major topic globally requiring sustainable corporate management. The Austrian packaging producer Greiner Packaging is meeting the challenge of this development with two approaches. Robert Obermayr, Product Group Director K1/K2, explains: - On the one hand, we are continuously optimising energy consumption and the production processes for processing classical plastic materials. On the other hand, we are pushing the use of alternative materials, in particular R-PET.
The responsible handling of raw materials and resources characterises the sustainable actions taken by Greiner Packaging. Examples include saving energy through production equipment or reducing the weight of new packaging solutions. A particularly environmentally-friendly packaging technology is K3, the plastics-cardboard combination. It saves plastic material and can be separated well in terms of recycling. By using cardboard and recycled cardboard, we speak of renewable raw materials.
R-PET is taking an ever increasing role with respect to CO2 emissions and the conservation of non-renewable resources. Greiner Packaging can process R-PET at any existing PS plant at various production locations. Obermayr claims: - Major benefits when using R-PET are the reduction of the sealing temperature and very good peeling properties. Thus, valuable energy can be saved during the production process and CO2 emissions are reduced.
Greiner Packaging has already provided an array of packaging solutions made from R-PET for customers in Great Britain.
Great Britain and the USA in particular give fresh impetus to an increased use of R-PET. Major trading groups are making huge efforts towards climate protection. In doing so, they offer the means for orientation, such as scorecards or carbon footprint labels to manufacturers, suppliers and consumers. These contain information on the CO2 emissions generated during the production of the product concerned.
- The less CO2 emitted during the production of the package, the more interesting the final product is - explains Obermayr. - Moreover on the market in Great Britain, rubbish collection fees are reduced in proportion to the percentage of recycled R-PET contained - he adds.
R-PET originates from PET bottles, which become part of the so-called “homogeneous material circuit”. They are pressed in bales and then cut up and cleaned in specialised recycling companies. During this procedure flakes are created, which are normally processed further into granulate. The further processing of R-PET includes the reconstruction of the molecular chain.
Greiner Packaging is one of the leading companies in the European packaging industry. In 2008, the company achieved annual sales of EUR 376 million or 34 per cent of the total Greiner Group sales. Greiner Packaging employs a workforce of 2,935 employees at 21 production sites throughout Europe.
Greiner Packaging manages its business sustainably and counts on R-PET
