Basic Research of Material Properties of Mycelium-Based Composites

Area of Science:

• Mycology
• Material Science
• Sustainable Architecture

Background:

• The construction industry significantly contributes to global CO2 emissions.
• Developing sustainable building materials is crucial for environmental impact reduction.
• Mycelium-based composites present a carbon-neutral alternative to conventional materials.

Purpose of the Study:

• To investigate the fundamental material properties of mycelium-based composites.
• To assess the viability of mycelium composites for architectural applications.
• To establish a foundational database for future research and development.

Main Methods:

• Cultivation of mycelium composites using beech sawdust substrate.
• Evaluation of two specific mycelium strains: *Pleurotus ostreatus* and *Ganoderma lucidum*.
• Material characterization including density, compression, flexural strength, and water absorption tests.

Main Results:

• Mycelium composites demonstrated suitability for compression-only structures and insulation.
• Material and mechanical properties were quantified and compared.
• Data on density, strength, and water absorption were systematically collected.

Conclusions:

• Mycelium-based composites show promise as eco-friendly building materials.
• Further research is needed to optimize properties and expand applications.
• The study provides essential data for defining the potential and limitations of mycelium composites.
