Abstract

Sustainable product-service systems (PSSs) have proven to be a very good alternative for developing new business models and transforming traditional offers into sustainable ones. Environmental, social and economic benefits support the idea of developing this type of system. However, there are identified challenges that have stopped the expansion of the concept into the market. The framework that explains the principles and building blocks of a circular economy according to the Ellen MacArthur Foundation can be an interesting lens to analyse the challenges companies faced when they wanted to implement a sustainable PSS. This framework is particularly useful to understand the internal and external forces companies are dealing with in a transformation from traditional business models to ones like sustainable PSSs that need special conditions of operation. Design for sustainability as an area of study will shift in the coming years to focus its attention on the requirements of circular economics as the paradigm of production and consumption. Sustainable products, services and systems will be developed according to the conditions established by those circular conditions.
