Plastic: Part of the Problem . . . Part of the Solution – Part 4: Efficient Use of Recyclates

The problem of plastic waste seems insurmountable. The good news is plastic recycling is on the rise and that is good for the circular economy. In parts 1, 2 and 3, we delved into the role of the waste management and recycling industry and how material sorting technologies can help. Part 4 is all about the increased use of recyclates as an essential part of properly closing the plastic cycle.

The plastics industry is facing a great many challenges. Harvesting recyclates from waste is only worthwhile if the plastic has been properly sorted and does not contain any metal, and if the products made from the secondary raw material are similar in quality to those made from new plastic.

Manufacturing recyclates from plastic waste is the first step. But in order to fully close the plastic cycle, more recyclates need to be used in the manufacturing of new products. This is a lucrative business for plastics processors, as recyclates are cheaper than new materials.

With material costs in the plastics industry accounting for 40% to 80% of total expense, depending on the segment, using recycled materials can significantly increase profitability. In addition, the secondary raw material in its ultra-pure state has practically the same characteristics as new plastic.

Yet there are still a number reservations in the industry when it comes to recyclates. The quality of the input material is particularly important in this regard. Recyclates must be free from any contamination to protect processes and machines from damage and ensure that the final products meet high standards of quality.

Plastic: Part of the Problem . . . Part of the Solution – Part 3: Sorting Technology

As I mentioned, this 4 part presentation is being done by Sesotec GmbH, a company which manufactures recycling equipment. Even so the information given by Sesotec is to the point on the topic of pollution by man made packaging and products which can be sued again and again and in some cases up to 8 times. Fair warning as the pitch comes with regards to Sesotec’s abilities.

Around 70 years after the first plastic product hit the market, a world without plastic waste now seems like a distant vision. It’s time for a new perspective on this supposed waste. In the third instalment of our series, we focus on how we must all manage how we deal with plastics in future, and the role materials sorting technologies and contaminant detection systems play in recycling.

Each year, Europeans generate 25 million tonnes of plastic waste. At a global level, 78 million tonnes of plastic waste is created annually. The world has to respond to this global problem together, as recycling rates everywhere have been at a low level so far: 30% in Europe, 25% in China, and just 9% in the USA (Plastikmüll-Statistik 2017). A large portion of the supposed waste is still incinerated, or ends up in landfills and the environment, which harbors risks for our water, air, and food chain.

To achieve a Circular Economy, it’s important that all players contribute to this task: from product design and manufacture on the part of the plastics industry, along with conscious use and avoidance of plastics as well as waste separation on the part of consumers, followed by proper recycling and sorting by the waste and recycling sector, all the way up to conversion into high-quality secondary raw materials and their use in the manufacture of new products.

Plastic: Part of the Problem . . . Part of the Solution – Part 2: the European Union’s Solution

As you can read for yourself, this is the second part  of the series. This part will introduce the EU’s proposed solution to plastic waste material of which Sesotec is to be a part of the solution. Since I am using Sesotec’s information, I will be stating their name as owner’s of this information from time to time.

Some 70 years after the first plastic products hit the market, a world without plastic waste still appears far off. We need a different approach to dealing with what many consider to be rubbish – and we need it fast. In this multi-part series, we will take a look at the role that the waste management and recycling industry can play in the process. Part I took us to China. Now it is time to take a look at Europe.

China is no longer taking on the world’s plastic waste, and our oceans could soon be home to more pieces of plastic than fish. The time to act is now.

There are many ways to reduce plastic waste. Banning their use is one of them. A great deal of plastic packaging is, in fact, unnecessary. Yet it also offers benefits in certain areas, such a hygiene and shelf life, making a complete ban rather unrealistic.

Another approach is to avoid plastic in many situations and to practise “plastic fasting”. Still, even that will not work everywhere, especially in the industrial sector. It is therefore essential to find an alternative solution – one that is also reflected in the EU’s plastics strategy: a circular economy.

The European Union presented its plastics strategy on 16 January 2018. Under the strategy, all plastic packaging must be either reusable or recyclable at low cost by 2030. One of the EU’s goals in its plastics strategy is to stop marine litter. The long-term goal must be to avoid marine plastic waste entirely. However, creating a circular economy and recognising the value of a material that is widely considered to be refuse will be essential to achieving this aim.

The overall EU strategy is based specifically on four basic tenets:

  • manufacturing recyclable products
  • optimising the separation and collection of plastic waste
  • increasing recycling capacities
  • reusing recyclates in production
