Recovery And Reuse Of The Entire Process Of Processing

After the bales entering the rPlanet Earth workshop are separated into separate bottles and thermoformed containers, multiple sorting processes are performed. The magnetization sorter removes debris such as wires; the near-infrared scanner identifies the PET material and separates it from other polymers, and an additional sorting step sorts the PET materials by color.

Next, go into the drying process and press the material into a thin sheet. In this step, pay attention to waterproofing, because water can carry ink and adhesive, which will affect the quality of recycled PET products. The first involvement of water is the washing process before the material is moved into the recovery tank. During this process, the PET material with a higher density than the water sinks and the labels, binders and other impurities are removed.

In the final step, the flakes were fed into a Krones MetaPure reactor at a temperature of 200 and vacuum. The SSP raises the viscosity of the recycled PET material to different standards depending on the needs of the intended use.

rPlanet Earth uses its own plastic processing line to skip the granulation step and add value to the flakes. “By bypassing the granulation step, it is possible to prevent the appearance of the product from being damaged, because the color effect of the melting process can be completely avoided,” said Mr. Daviduk. “Our customers are looking for products made from real closed loop recycling systems.” He said that rPlanet Earth can provide 100% sheet, thermoformed packaging products and models made from recycled PET, depending on whether the customer asks for it or not. A certain proportion of the original PET material.
