The 4.9 million cubic metres of waste is five times greater that estimated for the Malta to Gozo tunnel, which is projected to produce one million cubic metres of waste if carried out. Land reclamation is one of the options to dispose of the construction waste. The calculation is based on an estimate provided by international experts appointed by Transport Malta to conduct a technical study for a proposed metro. Arup was appointed as consultant in December 2016. In its consideration on the best transport system, Arup considered five options: a bus rapid transit, a surface tram, the proposed underground light metro, an elevated light metro, and a combined system with an underground light metro and a surface tram. Each of the modes were then assessed under certain criteria which included capital and operational costs, the reliability and quality of public transport, and the impact on existing transport networks. The underground light metro option was chosen as the preferred one because...
