Recycling of construction and demolition waste produce materials, which can be used as primary resources replacement. However, these recycling processes can be very energy consuming and therefore environmental impacts of such processes should be considered. We assessed environmental impacts of recycled concrete and brick aggregates and also environmental impacts of products with recycled content. The Life Cycle Assessment method was used as analytical tool for evaluating environmental impacts of recycled materials (1 t of concrete or brick aggregates), products (1 m3 recycled concrete mixtures) and constructions (blocks and building foundations). Also, various effects on environment were discussed such as ecotoxicity of concrete products, the consequence of landfilling limitations and carbonation effect. We present the results of environmental impacts assessments to show, what influence the chosen function of recycled product has. We suggest to assess environmental impacts of recycled aggregates considering their future function.
