Benefits of Smart Technologies Current Scenario : Riyadh has approximately 1,400 waste collection vehicles. The annual contract for waste collection is 500,000,000 SR. Daily cost per waste collection cycle for one truck is 970 SR. Benefits of Smart Collection : Case studies from Malaysia and South Korea showed cost reductions in waste collection by 50% and 43% respectively. If Riyadh adopts a conservative 40% reduction in waste collection costs through smart monitoring systems: Cost per cycle per truck would decrease to 582 SR/Day. The annual cost would drop to 297,402,000 SR, a savings of 202,598,000 SR. Potential of Recycling in Riyadh : Using U.S. Environmental Protection Agency (EPA) data as a reference for recycling potential: Plastic : 9.5% recyclable, with an annual volume of 61,898 tons. Potential revenue: 77,372,500 SR. Metal (aluminum) : 3.1% recyclable, with an annual volume of 5,592 tons. Potential revenue: 27,728,000 SR. Glass : 26% recyclable, with an annual volume of 49,236 tons. Potential revenue: 22,156,000 SR. Paper : 65% recyclable, with an annual volume of 423,510 tons. Potential revenue: 50,821,000 SR. Total Estimated Recycling Revenue : If all recyclable waste is utilized, the estimated annual revenue is 178,077,700 SR. Source : F K Alqahtani et al 2022 IOP Conf. Ser.: Earth Environ.
