Lithium-ion batteries (LIBs) have consolidated their place in the technology market for the energetic transition, with global manufacturing capacity exceeding 1 TWh in recent years and costs falling in this competitive environment. At the same time, the number of end-of-life LIBs is increasing, stimulating the recycling industry to process battery streams, thus promoting the circular economy to meet the increased demand for strategic raw materials and decarbonization. Vehicle electrification is the main driver of battery production, but their end-of-life will take some time to be significant in volume in the next years. Consumer electronics such as smartphones, laptops and power tools are now available at an appropriate volume enabling the preparation of recycling industry for the moment. In this scenario, recyclers are looking for sustainable routes to absorb all these streams and the different LIBs chemistries (LFP, NCA, NMC, LCO, LMO) to recover the critical metals (Ni, Co, Cu, Mn
In response to increasing environmental awareness and the automotive industry's push for sustainability, the development of lightweight and robust components has become a key area of focus. This paper presents a multidisciplinary approach to the design and optimization of an aluminum parking brake lever, leveraging advanced structural optimization techniques to enhance performance while meeting stringent environmental standards. Traditional manufacturing processes for automotive components, such as stamping, often rely on steel due to its strength and ease of processing. However, the high density of steel can significantly impact the overall weight of the vehicle, leading to increased fuel consumption and emissions. In contrast, aluminum’s superior strength-to-weight ratio offers a promising alternative. This study employs Finite Element Analysis (FEA) to model the initial stress history of the lever, followed by the application of structural optimization tools to refine its geometry
Whether it’s the meeting room of an office building, the exhibition room of a museum or the waiting area of a government office, many people gather in such places, and quickly the air becomes thick. This is partly due to the increased humidity. Ventilation systems are commonly used in office and administrative buildings to dehumidify rooms and ensure a comfortable atmosphere. Mechanical dehumidification works reliably, but it costs energy and — depending on the electricity used — has a negative climate impact.
The path toward carbon-neutral mobility represents one of the greatest cultural transformations in recent human history. Positioned between industrial heritage, emerging mobility technologies, and the energy supply sector are the users of 1.5 billion motor vehicles worldwide. Conflicting publications on raw material availability, energy efficiency, and the climate neutrality of propulsion systems have led to widespread uncertainty. This Illustrated Energy Primer provides a new foundation for orientation. It begins with a visual explanation of the basic concepts of energy and power, followed by illustrative comparisons of typical energy demands in vehicles and households. The focus then shifts to common types of energy generation systems. Using regional examples—from coal-fired power plants to wind farms, solar installations, and balcony solar panels—the guide provides clear and accessible performance benchmarks for energy production. Next, nine individual experience profiles highlight

Why smart electrical distribution is the new frontier in sustainable manufacturing. From transitioning to renewable energy, embracing the circular economy and pursuing carbon offsets, today's automakers are actively working to become more sustainable. Many OEMs have big goals to become fully carbon-neutral by 2050. Some believe they can get there even earlier. But look past the cars and sources of energy right into the factories in which the vehicles of today and tomorrow are born and focus on a key question: how can carmakers make significant strides inside their plants to cut waste and improve sustainability?
The next generation of mobility, driven by shared, driverless, connected, and electrified vehicles, holds strong potential to advance sustainability through lower emissions and improved resource efficiency. However, critical questions remain regarding their true environmental impact, including battery lifecycle management, material consumption, and circular manufacturing practices. Sustainable Circular Future Mobility: Environmental Impact of Next-gen Vehicles explores these unresolved issues, focusing on the shift from internal combustion to electric vehicles, supply chain challenges, regulatory gaps, and the operational realities of sustainable productization. It also critically examines the risks of greenwashing, the need for consistent standards, and the role of intersectoral collaboration—with energy, urban planning, information and communications technologies, and waste management sectors—in building resilient, scalable solutions. The report provides strategic recommendations and
Suppliers are learning several new and unwelcome lessons as the dynamics surrounding U.S. light vehicle trade and emissions legislation quickly shifts. Two major issues are at play here. As the industry continues to feel the impact of reduced or eliminated battery electric vehicle incentives in several North American and European jurisdictions and governments are retrenching on light vehicle emissions legislation - OEMs are questioning the size of the near- and mid-term market. Similarly, as of this writing, the saga surrounding future vehicle and parts tariffs between the U.S. and its major automotive trading partners continues. This unfortunate combination has driven OEMs to delay, extend and rescope future product programs. This jams a stick in the financial spokes of the supply base. Some context is in order. Like clockwork, in the highly competitive global light vehicle market, our industry was trained to expect a regular cadence for product renewals and product cycles. The
Cummins has expanded its Centum diesel generator series that elevates sustained performance while maximizing power density. The latest addition to the company's portfolio is a 17-liter engine platform that can provide up to one megawatt of power. “The S17 is engineered to redefine what you expect from an emergency standby package,” said Emily Scheuerell, Cummins power generation global engineering leader. According to Cummins, the S17 was a clean-sheet design that supports HVO (hydrotreated vegetable oil) fuel flexibility and complies with EPA Tier 2, UL2200 and CSA 22.2 emissions standards.
The American Petroleum Institute's (API) Proposed Category 12 (PC-12) is currently under development. A target first license date has been set for January 2027, and industry stakeholders are currently at work on PC-12's testing requirements, limits and other criteria that will make up the final performance category. That means change is coming to the heavy-duty diesel lubricants space. The introduction of a new category provides opportunities for enhanced lubricant performance in areas such as improved drain intervals, fuel economy and engine deposit protection. However, one major area of focus for next-generation lubricants will be greater protection and enablement of aftertreatment devices, helping heavy-duty OEMs comply with stringent new emissions standards set by the U.S. Environmental Protection Agency in 2022.
