A SOLUTION FOR QUARRY LIMESTONE DUST RECYCLING
2019
Quarry dust is a product of the extracting process. In quarrying activities, the rock is extracted and transformed into various sizes: as a waste, a fine aggregate generally useless to be disposed of and able to produce environmental pollution is produced. The disposal of this type of waste is a further cost of the extracting process, further it is a risk especially for subsoil reserves of wa-ter that can be easily reached during rainfalls and for the sea when quarries are close to the coast. The productive use of quarry dust with the double aim of disposal and protection of the environment seems a right strategy. The Italian-Maltese extracting industry covers a great segment in the world w…
Preliminary Evaluation of Plasmix Compound from Plastics Packaging Waste for Reuse in Bituminous Pavements
2021
Finding an appropriate technical solution for reusing waste plastics is crucial for creating a circular plastic economy. Although mechanical recycling is the best option for recycling post-consumer plastics, some heterogeneous mixed plastics cannot be recycled to produce secondary material due to their very low properties. In this case, alternative routes should be considered in order to limit their disposal as much as possible. Therefore, in order to solve the environmental problems in the landfills of plastic waste recycling, and to improve the mechanical performance of bitumen for road pavement, the reuse of these post-consumer plastic wastes are preliminarily evaluated for the modificat…
