Landfill is one of the most primitive and widely implemented waste management systems on earth. Adelaide has also depended on landfill. To achieve zero waste goals in Adelaide, certain disposal strategies should be considered in the future. Fig. 12 shows the experts' feedback on waste disposal systems in Adelaide. Even though half of the experts agreed that different initiatives should be implemented to achieve a 100% diversion to landfill, very few of them agreed that Adelaide should put restrictions, a ban or impose higher taxes on landfill use, on the contrary, they disagreed with both restriction and a higher landfill tax.
