Technology

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

Summary

Nutrition label

80% Informative

Only 30% of a coffee bean is soluble in water, and many brewing methods aim to extract significantly less than that.

Of the 1.6 billion pounds of coffee Americans consume in a year , more than 1.1 billion pounds are knocked from filters into compost bins and garbage cans.

Researchers developed a new system for turning used coffee grounds into a paste, which they use to 3D print objects.

They inoculate the paste with Reishi mushroom spores, which grow on objects to form that mycelial skin.
