How can pleasurable end-of-life experiences be designed for biodegradable packaging to support circular material flows?

Concept

The idea of biobased and biodegradable packaging materials as an alternative to petroleum-based, non-degradable ones is nothing new. One key reason they have not been used for a long time is that disposal infrastructure is lacking. The question of how these materials can be returned to the biological cycle remains unanswered.

 

The project “Designing the Afterlife” deals theoretically and practically with the development of disposal scenarios for seaweed-based, biodegradable packaging materials to close the biological material cycle and use the currently existing disposal infrastructure. The result is the “Water to Water” product series: packaging for solid and oil-based cosmetics that dissolves in water (the first time the product is used) and is disposed of in the sewage system, as it breaks down completely by microorganisms in the sewage treatment plant.

 

The work focuses on the communication of the product to the consumer. The packaging communicates how to dispose of it properly, with disposal designed to be simple. Part of the communication strategy is a QR code printed on the packaging, which leads to a video that explains the afterlife of the packaging clearly and playfully.

Water to Water

Intro

Beginning with the end of life, the project took as its starting point a seaweed-based packaging film developed at mujō, for which an adequate disposal infrastructure was lacking. The research phase included interviews and conversations with waste management experts. The findings revealed that existing systems – such as industrial composting – are unsuitable due to inconsistent regulations, limited processing times, and unclear benefits for waste operators. As a result, consumers are frequently confused about how to dispose of biodegradable packaging correctly. Based on these insights, the design brief aimed to enable the packaging to close the biological cycle within existing disposal infrastructures, while making the disposal process intuitive, clearly communicated, and user-friendly.

Development

Water to Water is a packaging series that rethinks disposal by making use of an infrastructure already present in nearly every household: the sewage system. To enable this approach, a fully water-soluble packaging for cosmetics was developed – including the film, adhesive, and printing paste – allowing it to be disposed of directly via wastewater.

 

In treatment plants, the material can be broken down by microorganisms, and the resulting sludge can be reused as fertilizer. In this way, the biological cycle is closed within the existing disposal infrastructure. The approach was validated through degradation tests conducted in collaboration with Berliner Wasserbetriebe, which showed that the material decomposed within approximately one week under real wastewater conditions.

Communication Design

A second central focus of the project was the communication of the disposal process. The packaging clearly indicated how it should be disposed of, making the experience simple and intuitive. As part of the communication strategy, a QR code printed on the packaging linked to a video that explained the packaging’s end of life in a clear and engaging way.
