and hot water. The label adhesive is then removed, and the material is mechanically and thermally dried. Finally, the air stream of the zig-zag separa- tor separates the bottles and caps from label particles according to their bulk density. To isolate the HDPE from the other components
for reuse at the end, the PP is separated using NIR technology. After compounding, it is regranulated into rHDPE and can be directly reused to produce new bottles. In the project,
Pla.to was able to produce 20,000 bottles through this method for recycling rHDPE. These bottles have passed all the necessary tests. They are dimensionally accurate, stable, odourless and have no imperfections such as specks or inclusions. Just like containers made from virgin material, they can be labelled and close tightly with a newly applied PP cap. “This proves that HDPE can be fully, efficiently and sustainably recycled with low wastewater on an industrial scale,” says Schnettler. Amut Recycling Technology has been selected
for Australia’s largest post-consumer PE recycling plant, which includes two washing lines. Amut and its Ecotech division have been awarded a contract to design and supply the plastics recycling plant, which will convert locally collected kerbside materials into high quality food grade rHDPE and rPP resin. Amut is the turnkey supplier for the Pact Group and Cleanaway’s Choir project, comprising a new plastic waste recycling plant in Victoria (which trades as Circular Plastic Australia), plus the two washing lines. Amut says it has been “chosen for his unique position as a company in the plastic waste recycling field able to supply turnkey plants including the front-end section for the best sorting solution and hi-tech washing plants (patented process) to achieve high purity on final flakes”. The Victoria plant will treat a stream of mixed plastic bottles in different polymers and colours, pots, trays and non-packaging plastics, ferrous and non-ferrous materials. It is expected to process

20,000-24,000 tpa of waste. Sorted plastics streams will include valuable materials, such as natural colour HDPE containers, coloured HDPE containers and PP containers. These materials, stored in separate buffers, will be automatically dosed to two washing lines. The first one with an output of 2,000 kg/hour is dedi- cated to natural colour HDPE containers, while the second with the same output is dedicated to coloured HDPE or PP containers. Both washing lines, if needed, are capable of processing natural colour HDPE for food grade applications. Amut says that its washing lines are equipped with the best technical solutions to guarantee high purity of the final PE flakes and in particular the removal of organic and inorganic contaminants and separation of labels and glue. In addition, a double stage friction washing system will complete the delivery, as it did for the country’s largest PET recycling facility in Albury, where Amut supplied the post-consumer PET bottle sorting and washing line, along with the final polymer and colour flake detector. These highly automated washing lines ensure extremely low operational costs with reduced power and water consumption. Amut has also supplied Viridor with the UK’s
largest multi-polymer plastic recycling plant. The facility in Avonmouth is powered by the energy produced at Viridor’s energy recovery facility, which is integrated with the plant. Amut’s Ecotech division designed and developed a custom-engineered plastic recovery facility integrated with a highly efficient washing plant. The turnkey facility process- es 90,000 tpa of waste composed of PET, HDPE and PP bottles to produce prime quality and high purity flakes and granules to be sold for food grade and commercial end use. According to Piergianni Milani, Amut Group’s
President, the company’s R&D department has developed recycling plants that minimise water and energy consumption and chemicals usage. The customised, automated washing lines reduce freshwater usage to 1.1 litre for each kg of high purity flakes of PET, HDPE and PP, due to its friction washer unit.
