🌿 New open-access study: indoor plants release negative air ions (NAIs) that help clean indoor air.
🪴 45 species tested
🌡️ Temp & humidity key factors
🔥 High temps cause a “rapid NAI surge”

#Hempcrete innovation update!
Geopolymer binder (70% clay, 30% CSH) = highest strength, but lower thermal & acoustic results
Hydrated lime + calcined clay + limestone = best acoustic & thermal performance
📊 XRD confirms stable structural phases

Our latest study on spent coffee grounds (SCGs) as a sustainable soil amendment!
Key insights:
Raw SCGs ≥ 35% is toxic.
Composting SCGs for at least 6 months reduces phytotoxicity & boosts growth.

Very often, 🏙️ cities become heat islands
Green cities are not only cooler, they also benefit our physical & mental health.
