Pre-study on circular street lighting

Important results from the project

The overall aim of the project is to reduce street lighting´s climate impact and material needs, by increasing circularity in the value chain. The goal has been to investigate the feasibility of new business models and new product design for publicly managed street lighting, regarding business ecosystems, organizational impact, and estimate economic and environmental effects.

Expected long term effects

The prestudy has contributed to an improved understanding about obstacles and opportunities for achieving more circular street lighting. Luminaires are relatively long-lived and considered measures are to ensure that they are resistant to external factors so that they can be used for as long as they are designed to do, as well as to use the lighting with care. The project has found that the concept of circularity is too comprehensive to be used in its entirety and suggests that it should be broken down into smaller components in order to more easily take steps in a more sustainable direction.

Approach and implementation

The prestudy included a global monitoring of similar challenges and previous research, semi-structured interviews with project actors, workshops both physically and digitally, as well as calculations of the economic and environmental potential with input from the project actors.
