Introduction: I am still on the mailing lists of quite a few resin and plastics companies. This particular presentation is from Sesotec GmbH (“company with limited liability”). Sesotec was an exhibitor at the K trade fair in Düsseldorf and now is reflecting on an exciting and positive trade fair appearance (for them) with its topic of a “Circular Plastics Economy.” This is part 1 of a 4 part presentation which I believe to be done in an exemplary manner and worthy of repeating.  Having cost modeled plastic parts at SY and Yazaki NA and purchased resins for Marquardt, Flex, and Stoneridge, I enjoyed the presentation.

This is why I thought this was worthy of presentation  at Angry Bear: “The K trade fair is held every three years and is an optimal opportunity to learn about current topics in the industry and to exchange information about these topics.

Marc Setzen, CEO of Sesotec GmbH: ‘We are more than satisfied with the results of the trade fair. With concern to the focal topic of the K trade fair, the Circular Economy not only is a technical challenge but also requires a change of the way people think. The attitude of plastics being throwaway products must be abandoned and people must become aware of the fact plastics being valuable reusable materials. Our machines and systems only are one component in the material cycle; but nevertheless, they make an essential contribution because they ensure the high quality of secondary raw materials made from recyclate and guarantee that the cycle really works.'”

This fits with what we must change to and be doing today.

Some 70 years after the first plastic products hit the market, the vision of a world without plastic waste still appears far off. Yet this substance – a plague once it becomes waste – is an extremely attractive material. What we need is a different approach to dealing with plastic waste. 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 1 takes us to a variety of destinations, including China.

The production of plastic has increased dramatically around the world in recent decades and currently stands at 200 times the amount manufactured by factories back in 1950. Europe is responsible for one-quarter of the world’s plastic consumption, mainly due to packaging that lands in the rubbish bin after being used for only a short time. Plastic is also used in construction (20%), vehicles (8.6%) and electronics (5.7%).

After the leap, how China and the EU are increasing the pressure . . .

China and the EU up the pressure

Even today, used plastic is often considered to be refuse and is seen as a problem that can be taken care of by simply throwing it away. In recent years, a large amount of used plastic has been shipped to China, destined for what many believed was a solution. Roughly 51% of the world’s plastic waste, or 7.5 million tonnes, ended up in China in 2017. At the time, China was the world’s largest importer of plastic waste. Transporting waste there by ship, and then loading the ships with new consumer goods for the journey back to their home countries, was long seen as a profitable business model. However, this cycle has since been made more difficult by China’s National Sword initiative. What is the idea behind it?

In January 2018, the Chinese government stopped the import of low-quality plastic waste as part of its National Sword programme. Only plastic waste with a purity level of 99.5% or more is still allowed into the country. China no longer wants to act as a dumping grounds for other countries. The Asian countries that subsequently stepped in at short notice to take on the waste have been overwhelmed and will eventually issue their own bans on imports. As a result, they are not a solution to the current problem, presenting the waste management and recycling industry with a number of challenges. Finding alternatives is an absolute must.

The EU has also acknowledged the problem. In early 2018, it adopted a plastics strategy, stating that all plastic packaging must be either reusable or recyclable at low cost by 2030.

The strategy poses another challenge for the waste management and recycling industry that ultimately places it in the same position as China’s National Sword initiative: ensuring the utmost purity of plastic waste prior to its recycling and reuse – an essential part of its ability to be employed as a secondary raw material.

Plastic – and no end in sight

The first plastic product hit the market in 1950. At the time, the world
produced around 1.5 million tonnes of plastic every year. In 2017, that figure
stood at roughly 350 million tonnes annually. A total of 8.3 billion tonnes of
plastic were manufactured between 1950 and 2017.
China is the largest producer of plastic (26%), followed by Europe (20%)
and North America (19%). According to estimates from Plastics Europe, plastic production is set
to increase to 1,124 million tonnes.

A floating problem

The world’s oceans are already home to 150 million tonnes of waste. Three-quarters of it is plastic waste, and 1 million tonnes is added to that amount every year. Many living creatures die a painful death as a result. So far, little research has been performed on the effects that plastics in the world’s oceans can have on the health of humans, who are exposed to it through the food chain. But what has been proved is that plastics take 350 to 400 years to decompose.

Packaging material disposed of along the shoreline, residues from rivers and fishing waste, such as leftover nets or ropes, are the main causes of marine pollution and the suffering of many marine organisms.

The long-term goal must be to avoid marine plastic waste entirely. However, creating a circular economy and recognising the value of material that is widely considered to be refuse will be essential to achieving this aim.

Tracking down marine debris

Plastic waste is mainly concentrated in five regions: in the north
Pacific, Indian Ocean, south Pacific, north Atlantic and south Atlantic. In
each region, the waste gathers close to the equator, where various water
currents and temperatures converge.

The largest patch of floating debris is the Great Pacific Garbage Patch
in the northern Pacific Ocean, with an area of roughly 1.6 million square
kilometres and an estimated 1.8 trillion pieces of plastic.

Purity matters

With plastic consumption and waste constantly on the rise, fast and efficient methods of recycling and reuse at the locations where waste is generated are of the essence. A new way of thinking and a new approach are also necessary from a sustainability perspective. Plastic waste can no longer be seen as rubbish. In times of dwindling fossil resources, it is a valuable commodity. Top-quality recycling material is the key to top-quality reuse.
