- According to the EPA, the average American generates 4.4 pounds of trash per day, which could be reduced through conscious consumption and buying less disposable items.
- Tips: Avoid single-use plastics, buy in bulk, choose products with less packaging, and adopt a low-waste lifestyle.
2. Reuse materials
- Reusing materials saves the emissions associated with extracting raw materials and manufacturing new products. The EPA estimates recycling 1 ton of paper saves 17 trees, 7,000 gallons of water, 4,100 kWh of energy, 60 pounds of air pollutants, and 3 cubic yards of landfill space.
- Tips: Donate old items, shop at secondhand stores, use reusable shopping bags and water bottles.
U.S. EPA: When cleaning, opt for reusable mops, rags, and sponges, and use cleaning products sparingly and according to directions to reduce waste.
3. Recycle waste
- The global recycling rate for municipal solid waste is around 32% 5. In the US, 94 million tons of waste were recycled and composted in 2018, equivalent to a 32.1% rate.
- Tips: Properly sort recyclables, avoid “wishcycling” non-recyclables, and support policies to improve recycling infrastructure.
4. Compost organic waste
- 25% of landfill waste could potentially be composted. Composting also avoids methane emissions; landfills are the third largest source of methane in the US.
- Tips: Start a home compost pile, participate in city composting programs, use compost in gardening and landscaping.
5. Combust waste for energy
- Waste-to-energy plants provide 2.2% of renewable energy in the US by combusting over 29 million tons of waste in 2018, avoiding over 16 million metric tons of CO2-equivalent emissions.

Understanding the Current Waste Management Landscape
The waste generation landscape is currently dominated by diverse sources, including domestic, commercial, industrial, municipal, and agricultural activities. The Gulf Cooperation Council (GCC) region is no exception to this phenomenon, with rapid urbanization and industrialization causing a significant surge in natural resource consumption. Consequently, this growth has led to increased emissions and posed considerable challenges to urban sustainability, necessitating a comprehensive understanding of the sustainable waste management landscape.
One critical aspect of sustainable waste management is striking a balance between economic development and the mitigation of environmental problems. To achieve this, a robust and integrative strategy for waste management is essential, one that aligns with the United Nations Sustainable Development Goals (SDGs). Among the viable strategies for addressing urban sustainability concerns is the Waste-to-Energy (WTE) process. This approach enables the production of clean energy while mitigating the harmful gases, such as methane, that result from traditional waste disposal methods like landfilling.
WTE processes provide a means to produce clean energy while mitigating the production of gases, including methane, from traditional waste disposal methods such as landfills.
By implementing state-of-the-art WTE facilities equipped with advanced pollution control technologies, it becomes possible to reduce emissions and recover valuable clean energy from waste materials. It is crucial to explore solutions that effectively address the challenges brought about by the escalating waste production, making it possible for future generations to enjoy a cleaner, greener, and more sustainable environment. The successful implementation of these strategies heavily depends on the collective efforts of stakeholders from various waste sources, engaging in best practices for urban sustainability and waste management.
