The combustion engine is dead, long live the combustion engine !?
The discussion about the end of the internal combustion engine has been part of every industry and climate debate for years. In 2025/2026, however, it has entered a new, contradictory phase: At the political level and in parts of the EU bureaucracy, there is a debate about postponements and adjustments to Euro 7/2035 rules; OEMs are responding with very different strategies in the product ranges; at the same time, suppliers and engineering service providers are pushing new co

Urban Mining: Waste is the New Ore
Urban Mining Gold in the trash – and Europe is sleeping through the opportunity China has shown the way: What was long considered waste is becoming a resource. E-waste – discarded smartphones, laptops, batteries, vehicles and industrial equipment – contains metals that are indispensable for modern technology. Copper, cobalt, nickel, rare earths, gold and silver are found in circuit boards and batteries – in concentrations that are sometimes higher than in natural deposits." U

🔋 Electromobility 2.0 – Beyond the battery hype
Why we can't just talk about reach now The discussion about electromobility has changed fundamentally in recent years. In the past, the question of whether e-cars would prevail at all was raised, but today it has long been a question of how we can make this transformation efficient, sustainable and suitable for the masses. The euphoria about ever longer ranges and ever larger batteries has given way to a more differentiated debate. The focus is now on topics such as: Second

As a result, the defence industry is also becoming the focus of governments, companies, investors and workers. More money,
