Swedish Innovations Aim to Revolutionize Environmental Cleaning and Excavation Safety

Two notable Swedish innovations announced on March 5, 2026, are advancing environmental and infrastructural safety. Researchers at Malmö University, led by Andriani Tsompou, are exploring purified water as an eco-friendly alternative to traditional detergents. Their work eliminates surfactants—which can damage skin and pollute water—by using purified water with increased pH to remove stains such as olive oil from glass surfaces. Removing oil from plastic proved challenging, requiring enzyme additives. Future research will expand stain testing to textiles and assess bacterial removal, with hopes to replace conventional detergents entirely.

In infrastructure, the Digital Ledningsanvisning project addresses excavation damages, costing Sweden approximately 400 million kronor annually. By digitizing utility information for real-time access in excavators, the project replaces cumbersome manual handling of data, thus improving safety and efficiency. After 15 months of successful field tests, organizations including Vattenfall Eldistribution, VTI, and RISE have jointly advanced this innovation. The project is nominated for Årets innovationsprojekt, with a decision expected this spring.

Mattias Moëll of Vattenfall emphasized the importance of collaborative efforts to tackle associated risks and challenges, while Sandra Hemlin noted that data quality and safety processes remain critical. Meanwhile, Tsompou is optimistic that purified water could soon supplant chemical detergents, revolutionizing laundry practices with environmental benefits.
