Single-serve coffee pods generate significant waste, with an estimated 40 billion capsules entering landfills annually. Traditional aluminum and plastic pods can take centuries to decompose, while their mixed material composition—combining metals, plastics, organic matter, and filters—makes conventional recycling challenging and often economically unfeasible.

The core challenge lies in developing pod materials and systems that maintain coffee freshness and brewing performance while enabling practical end-of-life disposal solutions.

This page brings together solutions from recent research—including polyhydroxybutyrate-based biodegradable capsules, automated pod separation systems, and reusable pod architectures with disposable filters. These and other approaches focus on maintaining beverage quality while addressing the full lifecycle of coffee pod materials, from manufacturing through disposal.
