Researchers at the University of Washington have discovered a groundbreaking method to transform used coffee grounds into a 3D printing paste. This paste, enriched with Reishi mushroom spores, creates a mycelial network that binds the material, resulting in a strong and eco-friendly alternative to traditional plastics. The study explores sustainable solutions for small businesses and packaging needs, aiming to reduce plastic waste.
• The paste, named "Mycofluid," combines coffee grounds, brown rice flour, mushroom spores, xanthan gum, and water.
• A specialized printer head was developed to facilitate the extrusion of Mycofluid, allowing for intricate designs.
• Objects like vases and statues were printed, with mycelium forming a protective layer that fuses separate parts together.
• The final product is biodegradable, with mechanical properties similar to polystyrene foam, and low water absorption.
This research is significant as it opens doors to sustainable materials from food waste, addressing the critical issue of plastic pollution. By utilizing coffee grounds, a common waste product, the project encourages innovative recycling and supports small-scale production of eco-friendly items.
