Welcome to C4CEC’s blog — a space where circular economy principles come to life!

At C4CEC, we focus on piloting innovations, advancing research, and developing practical solutions to transform coffee waste into valuable resources—from farming to consumption and disposal. But technical papers and best practice guides can only go so far. To reach a wider audience, we’re sharing real-world examples and interviews that highlight the full potential of circular economy solutions in the coffee value chain.

In collaboration with Dr. Hans-J. Langenbahn, we’re bringing you stories of circular transformation—spotlighting the people leading change and their entrepreneurial journeys.

Through these firsthand experiences, you’ll see how coffee waste is being repurposed into new opportunities, from turning coffee husks into biodegradable materials to using coffee pulp in food and incorporating spent coffee grounds into cosmetics.

By showcasing these innovations, we hope to make circular economy solutions more accessible, practical, and impactful.
