Coffee grounds and Reishi mushroom spores can be 3D printed into a compostable alternative to plastics

Summary by Science Daily
Researchers developed a new system for turning used coffee grounds into a paste, which they use to 3D print objects, such as packing materials and a vase. They inoculate the paste with Reishi mushroom spores, which turn the coffee grounds into a resilient, fully compostable alternative to plastics.

Coffee Grounds and Mushroom Spores Can Be 3D Printed Into a Compostable Plastic Alternative, Researchers Say

In a new study, researchers have made a promising discovery: a compostable material that can serve as an alternative to plastic. The material is made from a combination of used coffee grounds and spores from Reishi mushrooms that are made into a paste, then 3D printed. The idea started when Danli Luo, corresponding author of the study and doctoral student of human-centered design and engineering at University of Washington, noticed the amount of…

University of Washington: Coffee grounds and Reishi mushroom spores can be 3D printed into a compostable alternative to plastics | ResearchBuzz: Firehose

University of Washington: Coffee grounds and Reishi mushroom spores can be 3D printed into a compostable alternative to plastics. “[Danli] Luo and a UW team developed a new system for turning those coffee grounds into a paste, which they use to 3D print objects: packing materials, pieces of a vase, a small statue. They inoculate the paste with Reishi mushroom spores, which grow on the objects to form that mycelial skin. The skin turns the coffee…
