Analysis of the effect of incorporating construction and demolition waste on the environmental and mechanical performance of earth-based mixtures

•Assessment of environmental and mechanical performance of earth-based materials using CDW.•A correlation between mechanical strength and environmental impact is established.•CDW has shown potential to increase the compressive strength of earth mixtures.•CDW can positively contribute to the environmental performance of earth mixtures.•Studies on the replacement of binder in earth mixtures with CDW are encouraged.
