Germany is stepping up its game in sustainable building! 🏡✨ With new standardized practices for Building-Integrated Photovoltaics (BIPV), it’s becoming easier to incorporate solar energy into roofs and facades. A handy web tool is streamlining the process, and training programs are prepping tradespeople for this exciting shift.
This is a significant move toward greener cities and renewable energy adoption! 🌍⚡️

Denmark is painting the town red—for the bats. In a world-first initiative, the municipality of Gladsaxe has switched to red LED streetlights along key roadways to protect local nocturnal wildlife, particularly bat species sensitive to artificial light.
The core scientific insight is that traditional white and blue light spectrums disrupt bats' echolocation and feeding patterns. Red light, however, offers a safe, sustainable alternative that maintains public safety while preserving the local ecosystem.
This isn't just a quirky experiment; it's a smart blueprint for eco-conscious urban planning. The shift reduces light pollution and energy consumption, demonstrating how city infrastructure can meet global sustainability goals (like the UN SDGs) and successfully coexist with nature.

📰 Circular management of human excreta as a pillar of sustainable cities and food systems
https://hal.science/hal-05478504
This is the written summary of a presentation I gave at the annual meeting of the International Fertiliser Society (you can watch the presentation here: https://video.ploud.fr/w/qb3a8rXPxW7QQmWN7uBBKS)
I discuss the limitations of sewer-based sanitation in the face of climate change and increasing water scarcity: can we still afford the amount of water that is needed for sewers to effectively carry fecal matter all the way to the treatment plant?
Obviously I also mention how alternative management methods are being tested throughout Europe, including in large neighborhoods in Hamburg, Sneek, or Helsingborg (and soon Paris).

Human excreta (urine and faeces) is a major nutrient deposit; in the context of sustainable agri-food systems, it would in fact constitute the largest source of renewable phosphorus. However, current management through sewer-based sanitation leads to significant degradation of this resource as well as to the loss of the majority of the nutrients to the environment. This article details the flows of nitrogen throughout the French sanitation system and discusses the levers and obstacles to nutrient recovery in sewer-based sanitation systems. Using monitoring data from wastewater treatment plants (WWTPs) as well as records on population and dietary intakes, we assessed the flows of nutrients from food, through sanitation systems, and to the environment or environmental parcels. The mass flow diagram showed that 90% of the nitrogen and 50% of the phosphorus entering the system were not returned to agricultural fields but lost to the environment, thus inducing an intrinsic dependence on external nutrient imports. Though legislation has contributed to reducing water pollution by limiting the amount of nutrients discharged to the water, they have had little effect on recycling, especially for nitrogen. Further regulations on WWTPs are unlikely to enable the high nutrient recycling rates that could help secure domestic fertilizer supply chains. Because of this and given the vulnerability of sewer-based sanitation in the face of climate change and increasing water scarcity, we investigate the potential of excreta source-separation to provide high-quality resources for bio-based fertiliser production. We show that, if secured to fertilise crop production for human consumption, the nutrients in French excreta could cover a third of the nutrient requirements of domestic food consumption.
