Landfills are a major source of human-caused greenhouse gas emissions. As waste breaks down, it releases large amounts of methane (CH₄) and carbon dioxide (CO₂). These emissions, along with other by-products from decomposing waste, can harm nearby ecosystems and the health of surrounding communities. Air pollutants produced from organic waste (such as nitrogen oxides and fine particulate matter) are linked to serious health issues, including heart and lung disease. They can also trigger or worsen chronic conditions like asthma, bronchitis, and other respiratory illnesses.

In January 2022, California implemented Senate Bill 1383 (SB 1383), part of the state’s effort to reduce short-lived climate pollutants. This law focuses on cutting methane emissions as a way to slow atmospheric warming. When organic waste, such as food scraps, spoiled foods, yard trimmings, and certain paper products, are placed in green waste bins, they can be recycled through composting and turned into nutrient-rich soil. This process supports water conservation, improves soil quality across the state, and encourages recirculation of products that would otherwise be landfill waste. 

Although composting plays a key role in reducing environmental harm, cutting back on single-use and even recyclable items is equally important. Choosing reusable alternatives (such as durable water bottles, metal or bamboo utensils, and reusable shopping bags) can significantly reduce waste. Recycling should be considered a last step, following the waste hierarchy: Refuse, Reduce, Reuse, Recycle. Prioritizing reduction has the greatest environmental benefit because it conserves natural resources and decreases the volume of waste sent to landfills.

The most effective way to minimize landfill waste is to divert materials at the source by sorting them correctly. Organic and recyclable materials can be recovered and repurposed instead of being discarded. By making mindful choices at the point of disposal, individuals and communities can play a crucial role in reducing environmental impact and promoting sustainability.
