Pro Tip: Households with AI energy management save 20–30 % on monthly bills (World Bank 2024).

💧 2. Smart Water Management

• IoT sensors detect leaks and alert you instantly.
• Smart irrigation systems adjust watering based on weather and soil moisture.
• Rainwater harvesters connected to apps show tank levels and usage.

🗑️ 3. Waste Reduction & Recycling

• Smart bins with fill-level sensors notify collection services to avoid overflow.
• Home composters convert kitchen waste into fertilizer in 48 hours.
• QR-tagged recycling systems reward users for proper sorting.

🏠 4. Green Building Materials

Tech-enabled manufacturers now produce eco-friendly bricks, cool roofs, and insulating windows that reduce AC demand by up to 40 %.

🌿 5. Bangladesh’s Path to Sustainable Living

• Solar rooftop programs expanding in Dhaka and Rajshahi.
• IoT water projects piloted by Dhaka WASA for leak reduction.
• Municipalities testing smart waste bins for urban cleanliness.

✅ Conclusion
