Coffee lovers worldwide are increasingly aware of their environmental footprint, especially when it comes to single-use coffee pods. Traditional pods contribute significantly to landfill waste, as they are often made from non-recyclable materials. The quest for sustainability has led to the development of biodegradable coffee pods, aiming to reduce waste without sacrificing convenience or flavor.

Creating a pod that breaks down efficiently while preserving the coffee's quality presents unique challenges. Materials must withstand brewing conditions yet decompose in a reasonable timeframe. Achieving the right balance between durability and biodegradability requires innovative approaches, from plant-based wax coatings to fiber-reinforced bioplastics.

This page explores a range of solutions, including dissolvable beverage pods, compostable capsules with enhanced barrier properties, and automated systems for filling and sealing. These advancements aim to make sustainable brewing a reality, offering eco-friendly options that maintain the integrity of your morning cup.

1. Dissolvable Beverage Pod with Water-Soluble Body and Biodegradable Protective Cover

Ruben Perez, Maria Perez, 2023

Single-use dissolvable beverage pods containing coffee or tea powder that instantly makes a beverage when dropped into hot or cold water. The pods have a water-soluble body made of food-grade materials that dissolves completely in water. A biodegradable cover protects the pod before use. This allows users to make coffee or tea without machines or appliances by simply dropping a pod in water. The dissolvable materials reduce waste compared to traditional sachets.

2. Biodegradable Coffee Capsule with PHB-Based Polymer Blend and Enhanced Barrier Properties

MY TEA CUP AG, 2023

Single-use coffee capsules that are biodegradable and compostable, while having a good barrier function with regard to oxygen and water vapor. The capsule contains a polymer formulation that includes polyhydroxybutyrates (PHB) and optionally silicates, vitamin E, and proteins. The capsule container is injection molded from this biodegradable polymer blend and filled with coffee powder. The capsule also has a biodegradable seal. The PHB-based capsules have barrier properties comparable to aluminum capsules but can biodegrade in industrial and home composting.

3. Machine with Rotating Platform for Filling and Sealing Biodegradable Pods with Ground Food Products

Gorby LLC, 2023

A machine for filling and sealing single-serve biodegradable pods with ground food products like coffee. The machine has a rotating platform that moves empty pods to a filling station where augers or valves fill them. Then the pods move to a sealing station where a heated block seals and trims a film lid onto the pods. The machine automates the process of filling and sealing pods to produce single-serve packaged food products.

4. Compostable Capsule with Polysaccharide Shell Encasing Beverage Ingredient Core

DELICA AG, 2022

A compostable capsule for preparing hot beverages, like coffee, that is made of a compostable non-crosslinked polysaccharide shell encasing a core of beverage ingredients like coffee powder. The cladding material can be made of polysaccharides like carboxymethylcellulose, microfibrillated cellulose, sodium alginate, pullulan, or chitosan. The capsule provides a compostable alternative to plastic and aluminum coffee pods.

5. Recyclable Plant-Based Wax Coating Comprising Sugarcane Wax, Rice Bran Wax, and Calcium Stearate

J & J Green Paper, Inc., 2022

A recyclable, plant-based wax coating for waterproofing paper and cardboard food containers like cups and coffee pods. The coating composition contains a mixture of sugarcane wax, rice bran wax, and calcium stearate. This plant-based coating can be applied to paper and cardboard products to make them waterproof and suitable for hot beverages while still being recyclable and biodegradable.

6. Biodegradable Beverage Capsule with Polysaccharide Body and Polyvinyl Alcohol Coating

SWISS COFFEE INNOVATION AG, 2022

Beverage capsule that is biodegradable and environmentally friendly. The capsule uses a polysaccharide capsule body coated with polyvinyl alcohol and a polysaccharide layer. The coating layers provide gas barrier and water resistance. The capsule can be filled with beverage powder like coffee, tea, cocoa. It is suitable for beverage preparation by introducing water into the capsule.

7. Beverage Container Composed of Multi-Material Biodegradable Structure with Differential Decomposition Rates

G-PAK Technology Inc., 2021

Biodegradable single-use beverage containers that rapidly break down after use. The containers are made from two or more different biodegradable materials, such as bio-plastics or cellulose, that decompose at different rates. The faster decomposing material accelerates decomposition of the slower material when they are mixed together in the container.

8. Bioplastic Composite Incorporating Sunflower Seed Hull Fiber Reinforcement

SPC Sunflower Plastic Compound GmbH, 2020

Bioplastic using sunflower seed hull fibers as reinforcement to improve the mechanical properties of biodegradable plastics like PBS. Sunflower seed hull fibers are added to biodegradable plastics like PBS to improve mechanical properties like modulus. The sunflower hull fibers are obtained as a byproduct of sunflower oil production. The sunflower hull fiber reinforcement can be used in biodegradable products like coffee capsules and plant pots.

9. Compostable Beverage Capsule with Piercable Lid Featuring Weakened Portion

COSSA POLIMERI S.R.L., 2020

A fully compostable and biodegradable capsule for preparing infusion or soluble beverages like coffee that avoids the environmental issues of conventional capsules. The capsule has a body made of a compostable/biodegradable material and a lid closure made of a compostable/biodegradable material. The key innovation is the lid design that enables the use of compostable materials without sealing problems. The lid has a weakened portion that allows it to be easily pierced by a brewing machine. This avoids needing a sealing layer like aluminum or glue that wouldn't be compostable.

US10717592B2-patent-drawing

10. Compostable Multi-Layer Lid with Oxygen Barrier and Biodegradable Fiber Layer for Coffee Capsules

Ahlstrom-Munksjö Oyj, 2020

A compostable lid for sealing a capsule containing coffee, such as a coffee pod. The lid is made of layers that satisfy the conditions of use in coffee machines while being compostable. The lid has a support layer, an oxygen barrier layer, an adhesive layer, and a non-woven layer containing biodegradable fibers. The lid can seal the capsule without tearing when pierced, prevent coffee grounds from passing through, and provide an oxygen barrier. The lid layers are arranged in different configurations to balance properties.

11. Biodegradable Coffee Pod with Reusable Holder and Resealable Packaging System

Brett C. Richardson, 2020

Biodegradable coffee pod system as an environmentally friendly single-serve coffee option. The system comprises a biodegradable pod made of filter material containing coffee grounds, a reusable holder to keep the pod in place during brewing, and a resealable low-waste packaging for transporting multiple pods. The biodegradable pod can be placed in a compatible coffee machine, brewed like a regular coffee pod, and then disposed after use. The system aims to reduce the waste of single-serve coffee pods by providing a biodegradable alternative.
