As the world's population continues to grow, so does the amount of waste generated. Proper waste disposal is essential for public health and environmental sustainability. However, finding effective waste disposal strategies that balance environmental impact and economic viability remains a significant challenge. The traditional approach to waste disposal has been landfilling, where waste is buried in designated areas. Landfilling is a relatively cheap and straightforward method of waste disposal. However, it has several environmental drawbacks. Landfills can contaminate groundwater and release harmful gases, such as methane, into the atmosphere [1].

Incineration is another waste disposal method that has been widely used in the past. Incineration involves burning waste to reduce its volume and mass. While incineration can generate electricity and reduce the amount of waste sent to landfills, it also releases pollutants into the air, such as dioxins and heavy metals. To address the environmental concerns associated with landfilling and incineration, many countries have implemented waste reduction and recycling programs. These programs aim to reduce the amount of waste generated and promote the reuse of materials. Waste reduction involves minimizing the amount of waste generated by individuals and businesses. This can be achieved through practices such as composting, reducing packaging waste, and reducing food waste. By reducing the amount of waste generated, less waste needs to be disposed of, and the environmental impact of waste disposal is reduced [2].

Recycling is another critical waste disposal strategy. Recycling involves collecting and processing materials that would otherwise be thrown away and turning them into new products. Recycling helps to conserve natural resources, reduce greenhouse gas emissions, and reduce the amount of waste sent to landfills and incinerators. While waste reduction and recycling programs have been successful in many areas, they are not without their challenges. One of the most significant challenges is the cost of implementing these programs. Recycling and waste reduction programs can be expensive to implement, requiring investments in infrastructure, education, and outreach. Another challenge is contamination of recycling streams. Contamination occurs when non-recyclable materials are mixed with recyclable materials, making it difficult and expensive to separate them. Contamination can lead to the rejection of entire batches of recyclables, which can increase waste disposal costs and undermine the economic viability of recycling programs [3].

To overcome these challenges, governments and businesses have been exploring innovative waste disposal strategies that balance environmental impact and economic viability. One promising strategy is waste-to-energy (WTE). WTE involves using waste as a fuel source to generate energy. This can be done through incineration or through other processes, such as gasification and pyrolysis. WTE can generate electricity, heat, and fuel, and can reduce the amount of waste sent to landfills and incinerators. However, WTE is not without its challenges. WTE facilities can be expensive to build and operate, and can generate air pollution and greenhouse gas emissions. The environmental impact of WTE depends on the type of waste being processed, the technology used, and the management of emissions and waste residues [4].

Another promising strategy is the circular economy. The circular economy aims to keep materials in use for as long as possible, by promoting reuse, repair, and recycling. The circular economy can reduce the amount of waste generated, conserve natural resources, and reduce greenhouse gas emissions. To implement the circular economy, governments and businesses must redesign products and systems to prioritize resource efficiency and waste reduction. This can involve promoting the use of durable, repairable, and recyclable products, implementing extended producer responsibility programs, and investing in new technologies and infrastructure to support circular practices. Ultimately, finding effective waste disposal strategies that balance environmental impact and economic viability requires a comprehensive approach that considers the entire waste management system. This includes not only waste disposal, but also waste reduction [5].
