Quezon City is the largest and most populated city in Metro Manila, with a population of over 3 million people generating around 3,000 tons of solid waste per day. Around 54% of the city's waste is biodegradable, with kitchen and food waste making up 43.17%. Quezon City has various programs to manage its solid waste, including waste collection, materials recovery facilities, education campaigns, and projects to reduce waste. It also operates a biogas facility at its closed landfill that converts landfill gas into electricity. While the city has many programs, it still faces challenges in e-waste collection and management.
