2021 Disposal Facility-Based Waste Characterization Study

California Threw About 40 Million Tons of Trash in Landfills in 2021

To help California plan how to cut waste and pollution, CalRecycle oversees a study of what gets dumped into landfills, called California’s 2021 Disposal Facility-Based Waste Characterization.

California sent about the same amount of trash to landfills in 2018 as 2021, but sent 6% less organic waste with the statewide launch of food and yard waste recycling to cut landfill climate pollution.

California Recycling Programs Are Based on Scientific Research


To fight trash and climate pollution, CalRecycle conducts scientific trash studies to understand better what we throw away and what could be recycled. This information provides the foundation for new legislation, policy decisions, and programs targeted at reducing what we bury in landfills.

In 2021, CalRecycle conducted a landfill study to analyze how much residents and businesses throw away. This study also investigated different categories of food waste and packaging.

These studies provide detailed information about the types of materials we throw away and how our trash changes over time as new products are introduced to the economy. We also gain insights into how trash varies from homes to various businesses and how much recyclable material is not yet collected for recycling.

In 2021, CalRecycle conducted a disposal facility-based study at a landfill and sorted the material into 88 categories from 4 sources.
