Smart Planning of Waste Management System in Saudi Arabia; Challenges and Opportunities

Abstract

Solid waste management is one of the most critical problems facing urban areas worldwide. It is quickly becoming a significant issue in emerging countries with high population growth. Waste collection is a time-consuming procedure requiring enormous sums of money and meticulous logistics management. The amount of household waste produced in Riyadh has fluctuated over the years, with the majority being dumped in landfills instead of using them. This inefficient method of waste disposal has several adverse financial and environmental consequences, as landfills take up a large area of the city and emit foul odors and infections. An innovative waste management system should be adopted to address these difficulties, beginning with waste reduction and trash disposal in modern engineered landfills. Waste management solutions include reducing, reusing, recycling, energy recovery, and disposal. This research will focus on recycling, recovery, and disposal since social awareness campaigns could implement the first two strategies to reduce and reuse waste. The analysis also gives a sufficient cost analysis for the proposed methodology. This study opens new avenues for incorporating the value recovery aspect into garbage collection planning and the use of new data capture technologies that allow municipalities to track the mix of recyclables contained in various trash systems.

Evaluation of Multi-Utility Models with Municipal Solid Waste Combustion as the Primary Source under Specific Geographical and Operating Conditions

“…Manual sorting was conducted to segregate the different components. The generation rate was estimated to be 11,232 tons per day or 4,100,000 tons per year, which were dumped in a centralized dumping yard where 94% of the waste was dumped with the help of 1400 trucks [19] using the relationship given in Equation ( 16) [20].…”

Analysis of community participation in waste management that supports the agricultural sector in Takalar

“…Population growth with various activities, changes in consumption patterns and lifestyles increase waste volume, type, and characteristics (Alqahtani et al, 2022;Bulekova et al, 2022;Cahyani et al, 2022;Handayani et al, 2022 ). The composition of household solid waste was dominated by food and plastic waste (Sunaryani, 2022).…”

“…The composition of household solid waste was dominated by food and plastic waste (Sunaryani, 2022). The increase in the amount of waste is not balanced with the government's ability to handle it, so that waste becomes a complex problem faced by all countries, including Indonesia (Alqahtani et al, 2022;Bunditsakulchai & Liu, 2021;Cahyani et al, 2022;Mappau et al, 2022). So far, waste management is still conventional, namely collecting and transporting it directly to the TPA and not implementing optimal waste segregation (Aslam et al, 2022;Kovalenko et al, 2022), burning waste or throwing garbage anywhere, which causes accumulation of waste in various locations.…”

“…Some have carried out campaigns or counseling and assistance to implement 3R, set up waste banks, compost, decompose organic waste using magot, make regulations on waste, supervise and enforce laws, and provide adequate facilities and infrastructure, efficient transport routes using GPS. There are even areas that have converted waste into energy (Alqahtani et al, 2022;Bulekova et al, 2022;Fauzan et al, 2022;Janetasari & Bokányi, 2022;Ramaditya et al, 526 2022;Pratama et al, 2022;Sulistyaningsih, 2022;Sunaryani, 2022;Wahyuni et al, 2022;Xu et al, 2017). However, until now, waste management has not been satisfactory; for example, the 3R activities, namely reuse, reduce, and recycling, have not run optimally (Brotosusilo et al, 2022;Grishaeva et al, 2022;Mwanza et al, 2018;Ramaditya et al, 2021;Oktariani et al, 2022;Sulistyaningsih, 2022;Wahyuni et al, 2022).…”
