Can anybody tell me what this #fossil could be? My grandson discovered it in our backyard in outer #Melbourne, #Australia?
The rock in this area is #Silurian #sandstone.

I photographed the layered sandstone at Sunset Cliffs, where erosion and time shape the coast. Muted tones and gentle motion convey a quiet mood.

Which corner of your home would this view suit? Do you prefer the soft sky or stronger contrast? A subtle, grounding piece for your space.

This #GreenConcrete Is Made From #Urine: German Scientists Recreate Sandstone Texture Using Waste in #EcoTech Breakthrough

In a groundbreaking development that could redefine sustainable construction, researchers at the University of Stuttgart have successfully transformed human urine into a robust and eco-friendly bio-concrete, paving the way for innovative building materials that dramatically reduce environmental impact.

The bio-concrete’s chemical composition closely resembles that of natural #sandstone, indicating a harmonious blend with nature.

🌿 Researchers at the University of Stuttgart have developed an eco-friendly #BioConcrete using human urine.
🔬 The innovative process involves microbial #biomineralization, where bacteria convert urea into #CalciumCarbonate crystals.
🏗️ Bio-concrete offers a sustainable alternative to traditional concrete, reducing environmental impact and emissions.
🚀 The project aims to integrate bio-concrete into a #CircularEconomy, transforming waste into valuable building materials.

"In a groundbreaking exploration of sustainable construction methods, researchers at the University of Stuttgart have pioneered a method to transform waste into a valuable resource. By converting human urine into eco-friendly bio-concrete, they are paving the way for a new era of green building materials. This innovative approach not only seeks to reduce the environmental impact of construction but also leverages a commonly wasted resource to create something beneficial for society. The project’s implications stretch beyond mere construction, hinting at a sustainable future where waste is a key ingredient in building our world."
