Coffee pods offer convenience but create significant waste, posing a challenge for sustainability in the coffee industry. Millions of pods end up in landfills, with their complex materials making recycling difficult. Addressing this issue is crucial for reducing environmental impact and promoting a greener brew.

Professionals face the challenge of designing pods that balance usability with recyclability, while minimizing waste. The task involves developing materials that decompose efficiently or designing systems for easy separation and recycling of components.

This page presents a range of solutions, from biodegradable capsules with enhanced barrier properties to reusable systems with disposable filters. Discover devices for separating components and innovative designs for collecting and recycling used pods, all aimed at fostering a sustainable coffee culture.

1. Biodegradable Coffee Capsule with Polyhydroxybutyrate-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.

2. Reusable Coffee Pod System with Detachable Ring and Lid Assembly for Single-Serve Brewers

Savepod Inc., 2023

Reusable single-serve coffee pod system that reduces landfill waste while maintaining flavor compared to disposable plastic pods. The system uses a reusable ring, lid, and disposable filter to make a pod that can be used in single-serve brewers. After brewing, the ring releases the filter for easy cleaning. The pod assembly apparatus facilitates filling and assembling the pods.

3. Device for Separating Coffee Pods Using Penetrating Teeth and Dislodging Ridges

Connor Feeney, 2022

Device for separating single-use coffee pods into recyclable components for recycling. The device features a handle with teeth that penetrate and separate the foil lid from the pod, and ridges that dislodge the coffee filter from the pod rim. This allows the plastic pod, foil, and filter to be individually recycled, while the coffee grounds can be composted.

4. Reusable Coffee Capsule with Shell, Sealing Film, and Compression Hoop Mechanism

Xiaofeng LIU, 2022

A coffee capsule that can be filled multiple times with coffee powder and reused, reducing waste and cost compared to disposable capsules. The capsule has a shell to hold the coffee and a sealing film covering the shell opening. A hoop compresses the film edge against the shell to seal it. This allows the capsule to be filled and sealed with coffee multiple times while still fitting capsule coffee machines.

5. Reusable Coffee Pod System with Open-Bottomed Ring and Biodegradable Filters

John Mamtsaderis, 2022

Reusable single-serve coffee pod system that is environmentally friendly and provides a better tasting cup of coffee. The pod system consists of a reusable open-bottomed ring and disposable filters. The filters are biodegradable and can be quickly and easily assembled and disposed of using a dedicated assembly station.

6. Bag with Closure Flap and Extension Portion for Isolating Used Coffee Capsules

Mettler Packaging LLC, 2021

A bag for collecting and recycling used coffee capsules that provides a reliable way to collect used coffee capsules such as aluminum capsules for recycling without requiring cleaning. The bag has a closure flap, an extension portion, and optionally compartments. The bag is made of plastic layers with cavities that isolate the capsules. The bag can be filled with used capsules, closed, and shipped to recycling centers.

7. Device for Cleaning and Collecting Coffee Grounds from Reusable Pods with Housing and Filter System

GERARD LYNCH, 2021

A device to clean and collect coffee grounds from reusable pods used in coffee machines like Keurig. The device fits over the pod and has a housing to catch the grounds and a lid with a filter. After brewing, the pods are emptied by tapping or rinsing them into the housing. The grounds fall through the filter into the housing and excess water drains out. The filter can be disposable or reusable.

8. Coffee Machine with Integrated Capsule Opening and Emptying Mechanism for Recycling

ILLYCAFFE' S.p.A., 2021

A coffee machine with a used capsule disposal assembly that enables extracting beverage from capsules and then opening and emptying them for recycling. The machine has a mechanism that moves used capsules to a cutting device that opens the capsule lid with a partial cut to allow access to the contents. It also has a scraping device to extract all the beverage from the capsule. The machine separates the opened capsules from unopened ones and collects the empty capsules for recycling. The extraction chamber is removable for cleaning. The cutting blade has an opening to prevent full lid detachment. The machine extracts, opens, empties and collects used coffee capsules for recycling.

9. Device with Undulating Aperture Base and Plunger for Separating Infusion Capsules into Recyclable Components

Leslie Alexander Gort-Barten, Alexander Charles Gort-Barten, 2021

Device for separating single-serve infusion capsules like coffee pods into their recyclable components, such as plastic and aluminum, for recycling. The device has a base with an aperture to receive the capsule body and a plunger to push the capsule through the aperture. The base has a undulating surface surrounding the aperture that cause the capsule to deform and separate when pushed through.

10. Coffee Pod Dismantling Device with Adjustable Cutter and Size Adapter

Steven Jay Self, 2020

A device to easily and safely dismantle used coffee pods for recycling. The device has a handle, pod holder, and cutter. The pod holder securely holds the coffee pod while the cutter slices through the shell to open it. This allows the pod components to be separated and recycled. The cutter can be adjusted to cut just the shell or cut through the filter inside as well. An adapter is provided to accommodate smaller pods in the holder.

11. Liquid-Tight Shipping Bag with Adhesive Closure for Collecting Used Coffee Capsules

Mettler Packaging LLC, 2020

Simple and efficient recycling of used coffee capsules, particularly aluminum capsules, by providing a shipping bag designed for collecting and transporting the damp waste in a sealed and liquid-tight manner. The bag has adhesive strips for closure to prevent leaks during shipping. This allows users to easily recycle used coffee capsules without the need for cleaning them.

US20200071072A1-patent-drawing

12. Device with Chamber, Plunger, and Ejection Mechanism for Compressing and Discharging Used Coffee Pods

Walter Graham Magnus, 2019

A device for compressing and discharging used coffee pods to reduce their size and make disposal easier. The device includes a chamber that holds the pod, a plunger that compresses the pod, and an ejection mechanism to discharge the compressed pod. The plunger is moved back and forth using a handle to compress the pod inside the chamber. Once compacted, the ejection mechanism pushes the compressed pod out of the chamber for disposal.
