Biodegradable thermal and sound insulation boards from agro and medical waste

Overview

This innovative solution presents biodegradable thermal insulation and sound absorption boards developed from agro and medical waste. The boards utilize various binders such as wood adhesive and cornstarch to create polymer-bound or hybrid composites. By recycling waste materials like palm tree fibers, wheat straw, and discarded medical protective equipment, these boards offer an eco-friendly alternative to traditional petrochemical insulators. They boast a thermal conductivity coefficient between 0.04 and 0.07 W/mK and a sound absorption coefficient greater than 0.4 at certain frequencies, making them suitable for building applications.

Technical specifications

Key features:

• Utilizes agro and medical waste for material composition
• Low thermal conductivity (0.04 - 0.07 W/mK) for effective insulation
• High sound absorption coefficient (>0.4 at specific frequencies)
• Biodegradable and eco-friendly
• Thermally stable up to 200°C
• Low moisture content

The boards have been developed in a lab setting and are undergoing further mechanical and thermal tests to ensure performance comparability with existing insulation materials. Scanning Electron Microscopy has been utilized to analyze the surface morphology, and chemical composition testing has been conducted.

Technology readiness level

This technology is currently at TRL 5, indicating that it has been validated in a lab environment. Future plans include producing boards using a variety of waste materials based on trial results and customer feedback, along with comprehensive mechanical and thermal testing, to advance the readiness for commercial application.
