Background: Despite the obvious attraction for “greener” solutions in all industries, the different sustainable measures adopted by governments, business associations, andbusinesses themselves, the remaining high number of landfilled solid wastes from allindustries per year, especially the construction industry, suggests that a waste managementtowards valorisation is not systematically the first chosen option for the firms collecting the wastes. Purpose: To increase awareness, develop knowledge and show how collaboration within abusiness ecosystem and adapted corporate strategy allows the development of sustainablewaste management. Methodology: A comparative case study on the waste valorisation and innovation creationprocess, approached throughout a semi-structured qualitative data collection of fivepractitioners within a similar business ecosystem. Findings: The findings indicate that mutli-strategy level collaboration within and betweenbusiness ecosystems is a nursery for the development of innovation in the context of waste valorisation.
