Material Recycling of Polyolefin-Rich Plastic Fractions

The material recycling of plastic waste has still an enormous potential, even in countries like Austria or Germany, which have a highly developed waste treatment system. At the moment, approximately 2/3 of the utilized packaging plastics are treated thermally, i.e. as waste derived fuels, and only 1/3 are routed for material recycling.

Implementation of a Recovery System with Optimized Interfaces - The Total Plastic Concept

The German system for recovery of mixed dry recyclables has been established in the early 90s. It was installed to increase the recycling rates additional to the already existing system: the separate collection of papaer and glass.

Plastic Waste Recovery in Spain - Overview of the Market and Applied Technologies

Plastic consumption in different Spanish industrial sectors was 2.840.000 tonnes in 2010 and generated approxomately 2.206.000 tonnes of plastic waste in 2010. About 23% of this waste was recycled and 17% recovered, being landfilled about 60% [2].

Challenges of Mixed Plastics Recovery from MSW Sources in the United Kingdom

Part of the integrated waste management approach in the United Kingdom is a mechanical pre-treatment of MSW prior to either EfW (Energy from Waste) or AD (Anaerobic Digestion). As a consequence of the pre-treatment some unwanted material is being separated form the primary target material, and in most cases this material contains some valuable sub grades. One of these sub grades is mixed plastic. The amount and quality of recoverable mixed plastics within MSW depends firstly on the collection and transfer and storage scheme prior to the mechanical pre-treamtent and secondly on the consumer and education from the Local Authority who is ultimately responsible for the local or regional waste management strategy and education.

Recovery of Plastics from Household Waste by Mechanical Separation

Plastic packaging in the waste of private households used to be incinerated in the Netherlands until the end of 2008. In January 2009, a source separation system for plastic packaging waste (PPW) was established to reduce the amount of residual waste and secure access to secondary resources. Between 2009 and beginning of 2011 three mechanical-biological treatment plants started to recover PPW from municipal solid refuse waste of some municipalities.

Post-Consumer Plastic Packaging Waste - How to Increase the Yield and Reduce the Cost
© TK Verlag - Fachverlag für Kreislaufwirtschaft (10/2012)
Recycling schemes for post-consumer plastic packaging waste are politically motivated, create environmental benefits for the society and increase the business costs in general. These recycling schemes are shaped by the local presence of converting industries that are able to use the recyclates as raw materials. Choices for recycling schemes should therefore be based on the expected compliance, efficiency (the lowest environmental impacts for the least costs) and the present local industry.

Fields of Research in Optical Sorting of Different Types of Waste
© TK Verlag - Fachverlag für Kreislaufwirtschaft (10/2012)
Optical sorting appeared for the first time in 1994 in Germany, France and in the USA. Initially, it was limited to the recognition of the main packaging types, as found in the "yellow bin", using the NIR spectroscopy to differentiate molecular bonds: PET, HDPE, PVC, Tetrapak were the main targets. Colour sorting was later introduced for very fine colour nuances (e.g. clear vs light blue bottles). Today, most MRFs in Europe use Optical Sorting for packaging.

Industrial quality raw material: Mixed PET plastic can be prepared for mechanical recycling
© Deutscher Fachverlag (DFV) (6/2010)
The Fraunhofer Institute for Chemical Technology ICT in Pfinztal-Berghausen near Karlsruhe (Southern Germany) has developed and tested a process to prepare mixed PET (polyethylene terephthalate) from sorted packaging waste for mechanical recycling. The material can be used for injection moulded parts in technical applications.

"At first, they just smiled at us": PVC window recycling pays off
© Deutscher Fachverlag (DFV) (6/2010)
Apparently, recycling worn out PVC windows and doors pays off - at least for Veka Umwelttechnik GmbH. The eastern German company recently put its second recycling line into operation and is considered a specialist in the window recycling industry.

Complete utilisation of plastics: A study looks at the consumption and utilisation of plastics in Germany
© Deutscher Fachverlag (DFV) (6/2010)
Consumption of plastic in Germany continues to increase. The issue of waste utilisation in Germany has been clarified: more than 96 per cent of plastic waste is now utilised. Consequently, plastics are an important resource even after their first usage phase.
