A single-serve coffee container is a container filled with coffee grounds, used in coffee brewing to prepare only enough coffee for a single portion. Single-serve coffee containers come in various formats and materials, often either as hard and soft pods or pads made of filter paper, or hard aluminium and plastic capsules. Single-serve coffee containers can both reduce the time needed to brew coffee and simplify the brewing process by eliminating the need to measure out portions, flavorings, and additives from large bulk containers. They can also help to keep the unused product fresher by individually packaging portions separately without exposing the entire supply batch to air and light. Paper coffee pods can be functionally identical to plastic and metal coffee capsules, if the paper pods are individually sealed in separate bags. At the same time, the disposable single-use products add to global waste production.

History

In 1958, the Flemish Rombouts coffee company launched its pre-filled One Cup Coffee Filter for the Brussels World Exhibition. Unlike newer capsules and pods, this system consists of a single-use drip coffee filter placed over the cup. In 1964, the company began marketing the concept, gaining success in the horeca and retail sectors. The company was founded in Antwerp in 1896, and in 1966 was appointed a "Certified Royal Warrant Holder of Belgium".

Variations

Several different systems exist:

Comparison of systems

The plastic and metal coffee capsules typically are used in a non-removable receptacle on the brewing device. The capsules have an outer ring or rim that stays dry during use, allowing for removal and disposal after use without getting the user's hands wet or sticky. Handling of a used moist coffee pod is not necessary if the brewing device has a removable filter tray. This tray is removed after brewing and inverted to eject the used coffee pod. Coffee pods, bags, and capsules can be sized for individual or multi-serving portions. In food service businesses, pods and capsules used with automatic brewing can help to provide consistency of product strength and flavor for customers. Paper coffee pods such as those used in Easy Serving Espresso Pod or Senseo machines have the benefit of being a fully biodegradable product that can decompose naturally, while plastic and metal capsules such as those used in Keurig or Nespresso machines either are not recyclable, or require additional processing to separate the plastic/metal container from the organic waste products. Many capsule machines specifically warn the user to not disassemble the machine or put their fingers inside the capsule receptacle, as the devices commonly use sharp razor-edge tubes or prongs for piercing the coffee capsule during use. Different single-cup systems are not interchangeable; some systems force machine owners to buy capsules from a single company (usually the patent owner), locking the machine owner into a single source of coffee. Coffee pods are made by a variety of manufacturers and are interchangeable between brand of pod and model of pod brewer most of the time.

Environmental impact

Environmental activists have said that single-use coffee pods are harmful, as they are often composed of a mix of plastic, aluminium, and organic material (the used coffee) which makes them difficult to recycle. In early 2016 the German city of Hamburg banned coffee capsules from state-run buildings on environmental grounds. There are some capsules that are plant-based and that can be compostable as bio-waste.
