Recycling of this material, which is the symbol of construction today, becomes not only technical innovation, but also the needs of modern urban society. The paper presents basic ecology and economic criteria about use of recycled aggregates in concrete production. Some advantages of these materials are also presents. An accent is given to that we need to start thinking about our environment.
