The recovery/recycling of solid industrial waste is a major environmental, economic and productive reality in the context of waste management activities. One of the main aspects related to the application of recovery technologies is the removal of waste from landfills and it is sufficient to observe the consequent proportional decrease in quantities of industrial waste in landfills in order to confirm the progressive development of recovery technologies related to the world of waste. Disposal and recovery/recycling aim at minimizing environmental impacts and promoting the efficient use of resources. In the current landscape of waste recycling, there are consolidated activities in constant search of technological improvements aimed at optimizing recovery efficiency. In this context, the final goal of this study is the production of lightweight artificial aggregates through the recycling of industrial solid waste, such as fly ash, blast furnace slag, and marble sludge. The results show that the aggregates produced can be classified as lightweight aggregates and are suitable for road paving.
