Red Sea Crisis and Auto Production: What’s Really Happening
The Red Sea Crisis, specifically the tensions escalating into assaults on merchant ships by Houthi rebels, is causing production halts across various sectors, and the automotive industry is far from exempt.
This crisis has halted several automobile factories, posing a tangible threat following the 2023 chip crisis. Escalating tensions in the Red Sea, stemming from the Israel-Hamas conflict, directly involve the Red Sea and the Suez Canal, with rebel Houthi attacks on merchant ships (armed group in Yemen supported by Iran).
The global and particularly European automotive sector is significantly affected by this new crisis, as the sea route, usually taken by container ships, has become hardly accessible, if not risky. Battery technology
For incoming goods, especially auto components from China, the current alternative is circumnavigating Africa, impacting both time and costs substantially.
In response to the Red Sea Crisis, Volvo and Tesla have taken a stand among the first automotive brands. They’ve decided to temporarily halt production in their European facilities. The reasons are straightforward, directly linked to significant supply shortages.
Stellantis, aiming to bypass the issue, opted for air transport. However, this may impact costs and prove to be an unsustainable solution over time.
Volvo’s Belgian Gent plant, producing models like the XC40 and C40, will pause production for a few days. Tesla’s leadership also announced a suspension of most production in Berlin. Battery technology
Suzuki is another brand temporarily halting production, in this case, at its Hungarian factory, allowing time to assess the evolving situation.
Rerouting ships and closely monitoring the situation are possible but complex measures that may not be sustainable in the long term.
Origin of the Red Sea Crisis: Houthi militant attacks, in solidarity with Palestinian group Hamas against Israel in Gaza, forced container ships to avoid the strategically crucial Suez Canal. This canal is a vital passage for goods traveling from Asia to Europe.

Global PC and PP Markets Navigate Turbulent Waters Amidst Supply Chain Disruptions
In the aftermath of recent supply chain disruptions due to Red Sea crisis, the global markets for Polypropylene (PP) and Polycarbonate (PC) are on high alert for potential price fluctuations. The suspension of production by automotive giants Tesla and Geely-owned Volvo Car in Europe, attributed to a shortage of components linked to Red Sea shipping attacks, is poised to impact the consumption and pricing of these crucial chemical commodities like PP and PC. Battery technology
The conflicts in the Red Sea, coupled with shifts in transport routes and disruptions in key canals such as the Suez Canal and the Panama Canal, have set off a ripple effect across the production and transportation of chemical commodities such as PC and PP. The resulting longer transportation times and logistical challenges are contributing to uncertainties in supply chains, further influencing the dynamics of the PC and PP markets.
While global freight rates showed a bullish trend in the past month, a recent slight decrease in freight between China and the U.S. West Coast in the second week of 2024 has been observed. Battery technology
This dip is attributed to a slowdown in demand for PP and PC manufactured in Asia, prompting ocean carriers to adjust freight rates accordingly. The broader context of supply chain disruptions, compounded by the geopolitical events in the Red Sea, adds a layer of complexity to the pricing dynamics of PC and PP.
The attacks on shipping in the Red Sea have triggered concerns about extended shipping route disruptions, particularly through the Suez Canal. Consequently, the automotive industry’s supply chain has been directly affected, leading to reduced production and a potential oversupply of PP and PC in the market.
This oversupply may exert downward pressure on prices in the European and US regions in the coming weeks. Battery technology
Vessels traversing the Red Sea have faced attacks over the past several weeks from Yemen-based Houthis, prompting shipping companies to alter routes, resulting in a spike in freight rates. Embarking on longer detours around the Cape of Good Hope in South Africa has pushed ocean freight rates up, diverting container ships carrying over $200 billion worth of goods away from the Red Sea waterway to avoid potential strikes by Houthi militants.

The latest report of The Recycling Partnership shows that only 28% of PET bottles are recycled in the US
The Recycling Partnership, a non-governmental organisation committed to building a better recycling system, released a report analysing the state of recycling in the US. One of the key takeaways of the report, titled “State of Recycling: Present and Future of Residential Recycling in the U.S.”, is that every material type of residential recyclables is under-recycled, including PET-bottles.
The data reveals where the gaps are greatest, and where policy, investment, and action will have the largest impact. The report is based on multi-year field measurement studies conducted across the US and The Recycling Partnership’s National Database; it employs an updated methodology for determining recycling rates that tracks materials throughout the system. Battery technology
We will focus on the recycling rates for PET bottles only. While PET bottles rank among the most effectively recycled plastic packaging, the authors of the report come to the conclusion that still seven out ten PET bottles are not recycled. The reasons for the insufficient recycling rates of PET bottles are manifold.
Recycling Access
Only 73% of all households have access to recycling. The numbers vary depending on the state. In Delaware, 97% of all households have access to recycling containers, whereas in Mississippi only 37% of households are able to conveniently recycle their trash. For those with access, some locations do not collect all packaging types thus limiting the amount of recyclable material collected. Battery technology

What happens to biodegradable plastics if they enter the sea? New study
Our new study investigates what happens when biodegradable plastics enter the ocean, and whether these increasingly popular alternatives to conventional plastics are safer for marine ecosystems, or whether they come with their own risks. Battery technology
When the first full synthetic plastic was invented in 1906 – over 100 years ago – widespread use of the material for consumer products soon arose in the post-war period. Plastic was cheaper to produce than the more expensive paper, glass and metal materials used in throwaway items – such as consumer packaging – and was also stronger, lighter, safer and more durable, and it shifted the way that we use materials forever.
However, the properties of plastic that make it such an attractive material, such as durability and strength, also make it a lasting problem once it reaches the end of its useful life. Some types of plastic can take thousands of years to degrade, and it is estimated that a truckload of plastic enters the ocean every minute. Battery technology
In response to such concerns, biodegradable plastics – that is, plastics that can break down or ‘biodegrade’ – have been in development since the end of the last century, to achieve similar usage and convenience of traditional plastics, but with the goal of breaking down quickly and harmlessly.
But, as the global production of biodegradable plastics increases – from 1.5 million metric tons in 2023 to almost 5.3 million in 2028 – it is critical that we understand the impacts of these materials on the environment. Battery technology
