In conversion with Priya Rao,General Manager of Sikoplast Maschinenbau Heinrich Koch GmbH,Fritz Bufe discusses the benefits of PET recycling and its future prospects.
“By using good recycling equipment,rPET is more or less equal with virgin PET”
What are the advantages of rPET compared to virgin material?
By using good recycling equipment,rPET is more or less equal with virgin PET.So rPET could be used for the same high quality products instead of producing and using new virgin material.For our environment,this means we will get the same result with less energy and pollution.
What process is used to recycle PET?
This depends on the final use.For technical applications normally a washing line for PET post consumer bottle is used.As a result of this process,one receives clean and dry high quality flakes,which could be reused in most production line.For bottle to bottle or special products,the washed PET flakes are re-palletised after the washing line.The results are clean,filtrated rPET pallets.For bottle to bottle,the washing line is very often equipped with an acid stage to achieve highest possible cleanliness in combination with ultra friction washer for a mechanical surface peeling.
