Born out of an effort to make sure used coffee grounds do not go to waste, Alex White and his father-in-law John Mohr founded the eco-friendly venture 'Coffee Printed.' But instead of using the grounds as fertilizer or beauty products, the duo came up with a way to turn spent coffee into dyes for screen printing.

Coffee Printed is an e-commerce site that sells coffee-themed T-shirts made with coffee-based dyes. The coffee grounds are collected from local coffee shops and roasters and then brewed in a vinegar based solution. This process creates a thickened mixture that is similar to water-based screen-printing ink. The repurposed coffee ink is then used to dye shirts with humorous coffee-based designs such as a stylized French press or a mug decorated with the word 'LOVE.'

The unique venture demonstrates just one of the ways that businesses are using waste materials such as coffee grounds and giving them new life.
