Properly dispose of commercial hazardous waste

Conditionally Exempt Small Quantity Generators (CESQG) of hazardous wastes looking to dispose of them are welcome at the Materials Recovery Facility (MRF) without an appointment. Please note that disposal of household hazardous waste may be subject to facility fees. Learn more about CESQG here. Learn which hazardous wastes are accepted at the MRF and current disposal fees, here.

Soil Acceptance Application

Soil filters the water we drink, grows the food we eat, and captures the carbon dioxide that can be harmful to our environment. The Solid Waste Facility Permit for the Western Regional Sanitary Landfill (WRSL) prohibits the acceptance of contaminated soils; therefore, only clean soils are accepted at the Western Regional Sanitary Landfill. By filling out the Soil Acceptance Application, here, you will help us determine if -- and under what conditions -- your soil can be accepted by our facility.

Understanding commercial organics requirements

The WPWMA has been composting green waste since the mid-1990s and conducting small-scale composting of food waste from select businesses for several years. Now, with new statewide waste reduction mandates and the implementation of innovative technologies, the WPWMA is significantly increasing the amount of recyclables recovered, including commercial organics.

How to comply with California’s commercial recycling and composting laws

The WPWMA serves as a resource to help your business understand and comply with California’s recycling and composting laws. This section explains the reasoning behind the laws and offers information and additional resources to support businesses in complying with these waste and disposal mandates.

For Placer County contractors, please review this document for information on computing diversion and recovery rates for your projects.

When food and other organic materials decompose, they generate methane, a greenhouse gas over 70 times more potent than carbon dioxide over a 20-year span. Greenhouse gases play a significant role in climate change. Methane also contributes to public health problems, including heart disease and asthma. As of 2020, landfills produced at least 21% of the state’s methane emissions.

California is one of the first states in the nation to enact a statewide program to reduce greenhouse gas emissions through the diversion of commercial solid waste from landfills. As part of this effort, two laws established recycling requirements for businesses operating in California.

These laws are:

Methane emissions reduction targets for California set by law in Senate Bill 1383 (SB 1383, Chapter 395, Statutes of 2016) mandate that by 2025, organic waste disposal must be reduced by 75% and that at least 20% of currently disposed of surplus food must be recovered for people to eat. SB 1383 aims to reduce greenhouse gas emissions and remove up to 26 million tons of organic material from landfills annually by 2025. This change in organic waste disposal will reduce greenhouse gas emissions, help create thousands of new jobs, and improve the health of the state’s population.

SB 1383 requires all jurisdictions to provide organic waste collection services to all residents and businesses and recycle these organic materials using recycling facilities. All businesses must recycle their organic waste (food and green waste).

For compliance, a businesses must either:

  • Subscribe to and participate in their jurisdiction’s organics curbside collection service


  • Self-haul organic waste to a specified composting facility, community composting program, or other collection activity or program.

Businesses that sell food must also comply with these requirements under SB 1383:

  • Recover the maximum amount possible of surplus edible food generated
  • Partner with one or more food recovery organizations or services to pick up or receive your surplus edible food
  • Have a written contract or agreement with the food recovery organization(s) or service(s).
  • Track and maintain records of food recovered each month, including type, frequency of collection and amounts in pounds.

Approximately half of California’s waste stream is organic material like landscape trimmings, food waste, and lumber. Organic material can be diverted from landfills into composting and anaerobic digestion facilities, where it is transformed into soil amendments and biofuel. By 2025, California aims to reduce the amount of organic waste sent to landfills by 75%. To achieve this target, AB 1826 (Chapter 727, Statutes of 2014) requires commercial businesses to arrange for organic waste recycling services if they generate 2 or more cubic yards of solid waste per week. Please email if you have questions about commercial organics recycling.
