A socio-technical experiment with a resource efficient product service system

•A product service system (PSS) based on infant mobility products (car seats and pushchairs) achieved 1044 uses by families.•Multiple uses of products by different families were achieved, which supports the resource productivity of the PSS.•A quality assured refurbishing process was necessary to reassure users of the safety of using the pre-used rented products.•Environmental benefits included reduction of particulate plastics released in the environment and transportation.•The niche protected experiment exhibits good ability to predict pressures to be encountered in the open market. This paper describes a socio-technical experiment relating to a sustainable innovation project conducted in a protected niche or “living lab” and evaluates the ability of the experiment to generate learning and strategic direction. The study focused on a Product Service System (PSS) for renting infant mobility products to consumers. A PSS is a resource efficient system of products and services supported by networks and infrastructure. In the experiment, refurbished products were rented to 1044 families, with some products being reutilized three times. Learnings were generated through five stages: combining competences and resources, steering and facilitating change, engaging users at early stages, offering users opportunities to modify practices through trial and capturing and mediating mutual learning through knowledge co-creation. The observed environmental benefits included reduction of particulate plastic matter released into the environment and transportation of materials. Considerable barriers to the implementation of the PSS in the open market were identified, including attrition through loss or damage, product liability and consumer distrust in sharing products due to fear of contagion.
