The increasing demand for recyclates and the shortage of food-grade PET flakes pose challenges for batch quality and color consistency.

Repi offers various additives for recycling PET, which can be used, for example, to prevent the material from darkening.

“Nothing Speaks against the Use of Recyclates for Demanding Components”

The quality of recyclates can be improved very well by means of suitable additives. An overview of the variety of products and their suppliers.

Vitamins for the Circular Economy

The quality of recyclates is seen as too low. Improvements are possible by using additives, as was shown by the exchanges during the Forum Plastic Recyclates.

Quite clearly, the central theme of this year’s conference  was additives for recycling materials.

To close the recycling loop for end-f-life tires, Pyrum will in future produce pyrolysis oil from discarded tires using its own pyrolysis process. BASF will then feed this into its Verbund at the start of production.

End-of-life tires are tires that are no longer suitable or approved for their intended use.

“In difficult economic times, recycling is a reason to invest”

Interview with Korbinian Kiesl, President of Billion SAS

Mr. Kiesl, the circular economy requires that plastic recyclates can also be processed. How far advanced is Billion in this field?

The processing of recyclates has switched from being a vision to an everyday topic. These days, we no longer even ask ourselves whether our injection moulding machines can process recycled material. This is now a matter of course. Around 80 percent of our customers already run recyclates on our machines, some more, some less, but 80 percent is an immensely high proportion considering that almost no one was doing this a few years back. Three years ago, these customers were looking at K to see what was technically possible. They asked if we had any experience with these new materials. We were hardly ever asked this question about our experiences. Now, however, we are capable of dealing with concrete projects very quickly.

What role does quality play for your customers?

The more homogeneous the recyclate, the better the results for our machines, both in terms of physical properties and appearance, aesthetics. This requires a very good separation of used plastics. The machine can do everything, it‘s just a matter of whether you want to see the used recyclate or not. In the cosmetics industry – which represents an important customer group of ours – the use of recyclates was hardly conceivable until a few years ago. There, it was always a question of maintaining a flawless appearance. Today, there are customers in this industry who even want a package to show that it contains something recycled.

All customers today place their ecological interests and sustainable actions in the foreground. Within the consumer goods sector in particular, there is increasing pressure to do something. But as commercial enterprises, they are naturally looking closely at what is happening in terms of cost, plus there is a lot to be said for recyclates at present. Inflation, as well as the real cost explosion on the raw material side, be it virgin material or even all additives, mean that recycling is becoming more and more worthwhile. Recycling is a reason to invest, especially in difficult economic times.

Some users need their products to look good. What can you offer them?

If someone wants to have a smooth surface for aesthetic reasons, then our machine can make a product using the so-called sandwich process. The recycled material is inside the product. On the outside, it is surrounded by virgin material. The recyclate is therefore not visible. The prerequisite is that the chemical properties of the materials used are not mutually exclusive. For example, a furniture manufacturer uses our process to produce flower pots from recycled plastic. Customers from the cosmetics industry are also increasingly requesting this method. In times like these, it is also worthwhile in terms of cost. The product is still flawless on the outside, and cheaper recyclate is processed on the inside.

The process works with multi-component technology. There are two injection units that bring the different materials together. We first inject the virgin material into a mould. It clings on the inner walls. Then the second material is injected into the centre of the part, and finally the initial material is used to close the mould, so to speak.

In 2019, you had future ideas and visions, in 2022 you have the products and the customers who use them. What’s next on the agenda?

More and more users will utilise recyclates. This trend is irreversible. In addition, it is already becoming apparent today that non-polymeric waste will also be processed. Our customers are already occasionally making products from biomass. They obtain the material from composting plants. These products are then biodegradable at the end of their lives. The use of renewable raw materials and biodegradable raw materials, including biodegradable plastics, will definitely increase in the coming years. Certainly, it will not initially happen in such quality-sensitive areas as medical technology or the automotive industry. But in the consumer goods sector, in white goods or in packaging, for example, the use of renewable or biodegradable raw materials will rise.

2022-08-22 VDMA Interview Billion

The world is facing major challenges: climate change must be fought; the environment must be protected, and resources must be conserved. It is also important to make good use of the opportunities offered by digitalisation. The plastics industry has a key role in this process because plastics are ubiquitous in the world.

Climate protection, digitalization and the circular economy are therefore also the three major topics at K 2022, the world’s leading trade fair for the plastics industry. To get in the mood for the industry meeting in autumn 2022, the VDMA is letting representatives of the plastics machinery industry and all other stakeholders in the sector have their say through weekly interviews.
