26 patents in this list
Updated:
Single-use coffee pods generate over 100,000 tons of aluminum and plastic waste annually. While these materials effectively preserve coffee freshness and withstand brewing pressures of 9-15 bar at temperatures of 90-96°C, their environmental persistence has created an urgent need for biodegradable alternatives that maintain comparable barrier properties and brewing performance.
The core challenge lies in developing materials that can simultaneously provide oxygen impermeability, structural integrity during brewing, and complete biodegradability after use.
This page brings together solutions from recent research—including polyhydroxybutyrate-based polymers with enhanced barrier properties, polysaccharide shells with specialized coatings, multi-layer compostable lid designs, and plant-based wax waterproofing systems. These and other approaches focus on achieving commercial-grade performance while ensuring end-of-life decomposition in both industrial and home composting conditions.
