<p>This study investigated the relationship between biological effects and contamination profiles in sediments from 17 stormwater sedimentation facilities across four Swedish municipalities. Sediment extracts were...EN

Researchers combined two assessment techniques to simultaneously identify where groundwater is abundant and where it's vulnerable to contamination—a critical pairing for water-stressed regions. The approach, tested in Iraq, helps utilities and governments plan sustainable extraction and protection strategies rather than managing crises after aquifers are already damaged.EN

Swedish preschools with official environmental certifications teach sustainability no better than uncertified ones, according to a new study of 50 schools. The finding challenges the assumption that eco-labels drive meaningful educational change—and suggests policymakers may need different strategies to embed sustainability into early learning.EN

Researchers discovered that combining iron and sulfur compounds dramatically accelerates methane generation in thermophilic microbial cultures—a finding that could improve biogas production efficiency at industrial scales. The synergistic effect works only at high temperatures, offering a low-cost chemical lever for optimizing anaerobic digestion systems.EN

Researchers analyzed a peat bog in southeastern Iran and discovered a 2,600-year pattern of wet and dry cycles that correlates with cultural shifts and settlement patterns. The findings offer policymakers a historical template for understanding how climate volatility drives resource scarcity, migration, and social change—insights increasingly relevant as modern regions face similar water stress.EN

Researchers discovered that documenting and collectively reflecting on urban climate projects—through a method called "learning history"—helps cities learn faster and coordinate better. Three Swedish cities pursuing 2030 climate neutrality used this approach to identify recurring obstacles and adapt strategies, suggesting a replicable tool for accelerating transitions in other municipalities.EN

A new study identifies the psychological barriers preventing consumers from using digital platforms to recycle old phones, computers, and other e-waste. Understanding these obstacles could help businesses and policymakers boost recycling rates while tapping into a growing market for circular economy solutions.EN

Researchers have developed a dashboard that pinpoints exactly where factories waste energy by combining data from production systems, machinery, and power grids. The tool could help manufacturers cut costs and emissions simultaneously—a key advantage as energy bills rise and climate regulations tighten.EN

A new study found that rotating bed reactors remove dangerous PFAS chemicals three to sixteen times faster than traditional methods. But faster removal doesn't mean better long-term performance—a critical distinction for companies and municipalities investing millions in remediation infrastructure.EN

Scientists have detailed how a common compound released by pine trees chemically transforms in the atmosphere, producing volatile organic nitrates. The findings help explain how natural forest emissions contribute to air quality and climate, information crucial for refining pollution models and setting accurate environmental regulations.EN

A four-year study redefines the role of solar designers as relationship-builders rather than pure technicians, offering a three-layer framework that integrates personal expertise, technology, and ecological thinking. For companies and institutions scaling solar adoption, this insight suggests hiring and training practices need to prioritize design thinking and stakeholder engagement alongside engineering skills.EN

A new study reveals how multilateral negotiations on sustainable diets succeed by papering over fundamental disagreements rather than resolving them. Researchers found that consensus-driven UN policymaking masks conflicting interests through strategic ambiguity—a pattern likely affecting other global governance issues from emissions targets to supply chain standards.EN

A head-to-head test in Tunisia shows integrated solar water heaters outperform traditional thermosiphon systems by a significant margin, producing 25 liters of usable hot water daily versus 19 liters. The findings could reshape solar thermal strategies in arid regions where water scarcity and energy costs present major economic constraints.EN

Researchers simulated how four types of polymer coatings breach bacterial cell membranes, revealing that positively charged polymers are most effective at disrupting the protective outer layer. The findings could help manufacturers design better antimicrobial coatings for medical devices, reducing hospital-acquired infections and the need for antibiotics.EN

Researchers have cracked a long-standing waste problem: converting vinasse, a caustic byproduct of ethanol production, into edible fungal biomass loaded with protein and B-vitamins while cleaning the wastewater. The breakthrough could turn a disposal liability into a revenue stream for sugar-ethanol producers worldwide.EN

Scientists have discovered evidence of slow-motion lithospheric dripping—where chunks of Earth's crust sink into the mantle—beneath Europe's rift valleys. The finding reshapes how geologists model continental stability and could improve predictions of volcanic activity and seismic risk in economically vital regions.EN

A new analysis argues that incremental, fragmented climate adaptation approaches won't prevent societal collapse under cascading shocks. Researchers call for overhauls to governance, equity, and risk management—embedding adaptation into disaster planning and nature-based solutions—or risk making things worse.EN

Researchers have discovered how to convert sugarcane bagasse—a fibrous agricultural waste—into electricity using microbial fuel cells, with sewage as an added bonus improving efficiency. The finding offers industrial operators a dual payoff: generating renewable power while treating wastewater, potentially offsetting energy costs at sugar mills and treatment facilities.EN

A new study reveals that even in governance-friendly Nordic countries, most grassroots sustainability initiatives stall when expanding beyond pilot stage. Researchers identified three critical capabilities—stakeholder buy-in, policy integration, and sustained funding—that separate successful scaled programs from those that remain stuck at local level, offering a roadmap for companies and governments seeking to multiply climate solutions.EN

<p>Exterior building materials contribute to stormwater runoff pollution but knowledge of how ecological impacts may vary between different types of building materials remains limited. This study combined chemical...EN

A new analysis reveals that farmers avoid installing wetlands and buffers not because they don't work ecologically, but because the financial benefits flow elsewhere—to downstream communities and ecosystems, not to the farm gate. Closing this value gap requires new revenue models and business structures that let farmers capture returns from water management.EN

A new analysis reveals that Sweden's application of EU water protection law leaves room for interpretation on when environmental costs are "too expensive" to implement—creating uncertainty for renewable energy operators and policymakers. The ambiguity could delay ecological restoration projects or lead to inconsistent enforcement across Europe.EN

<p>In response to growing concerns over water scarcity and climate impacts in northern Europe, this study evaluates the performance and sustainability of rainwater harvesting (RWH) systems for non-potable use in...EN

Researchers have mapped how tilting water-in-glass solar tubes increases flow rates and reduces mean temperatures—findings that contradict decades of engineering literature. The discovery could reshape how companies design and optimize solar thermal systems for both residential and industrial applications.EN

Researchers studied how universal design principles are applied to playgrounds, finding that experts prioritize whole-environment planning over individual components. The findings matter for municipalities and real estate developers facing pressure to comply with accessibility standards while managing budgets and community expectations.EN
