National Waste Awareness Day, observed in Indonesia every February 21, commemorates the victims of the 2005 Leuwigajah landfill disaster, which resulted in at least 143 deaths. This day highlights the critical issues surrounding waste management in the country, particularly the rising amounts of plastic waste, with Indonesia producing over 3.2 million tonnes of unmanaged plastic annually. Events and activities are organized by the Ministry of Environment and Forestry, along with various local, national, and international environmental organizations, educational institutions, and community leaders. The day serves to emphasize the importance of responsible waste management and recycling practices. The Leuwigajah landfill, which was the primary disposal site for Bandung and Cimahi, experienced a catastrophic landslide due to unstable garbage piles, exacerbated by heavy rain and methane explosions, drawing attention to the dangers of poor waste management.
