| Abstract | Today, more than ever, the consuming society produces enormous quantities of wastes that have to be collected, stored and treated. But all these activities consume energy and pollute the environment. Using these wastes into the concrete industry has good consequences: eliminating the wastes and producing another type of material the green concrete. Since this industry expands, it is necessary to evaluate both characteristics: mechanical and environmental. Waste could be used as substitute for cement and for aggregates. The paper presents the results of a study on the mechanical properties and environmental performances of lightweight concrete prepared by substitution of sand in different percentages with chopped PET or wood waste. The new composite materials were experimentally tested by determining the mechanical characteristics and the embodied energy and global warming potential were evaluated. The eco-mechanical index for the experimented mixtures was also estimated. The study results introduce new types of building materials that use recycled materials, contributing to circular economy.
