What the Experts Say

"The plant will process the organic solid waste at a thermophilic temperature of 131°F (55°C). The higher processing temperature ensures that spores, bacteria, and harmful seeds are eliminated, completely sanitizing the organic matter during processing. Equally important, the higher temperature permits the carbon-neutral biogas potential to be fully exploited."

How We Create Good Things from Green Waste

When you collect your kitchen scraps, food waste, lawn trimmings and other green waste and put them in your green bin, it comes to our state-of-the-art renewable energy and recycling facility. 

In 30 days, your organic waste is converted into all-natural compost and liquid soil amendment, used by local farmers and wineries to grow healthy crops. The recycling process also creates carbon-negative biogas that is turned into renewable electricity.

It all adds up to a clean, sustainable way to turn waste into valuable materials, reduce our carbon footprint, and divert waste from landfills.

In addition, it helps achieve the 75 Percent Initiative launched by California in 2011, which sets out the state’s declared goal of achieving a 75% reduction in total waste by 2020.

How Can You Help?

Here are some easy tips to know what goes in your green bin.  

Did you know you can put all sorts of food waste into your green bin? Leaves, grass clippings, produce trimmings… and SO much more. 
And even better and easier for you — just put your organic waste directly into your green bin. No compostable baggies needed. 

  • Our digester loves to eat: 
  • Kitchen scraps from vegetables
  • Kitchen scraps from meats
  • Dairy and egg waste (including shells)
  • Coffee grounds and tea leaves
  • Meat (including bones)
  • Fish and shellfish (including bones)
  • Fat
  • Lawn clippings
  • Leaves
  • Brush and vines (maximum 3 feet long and 6 inches diameter)
  • Our digester can't eat: 
  • Plastic bags (even the compostable ones)
  • Lumber and wood scraps
  • Cans and glass
  • Diapers
  • Pet and animal waste
  • Rocks and dirt
  • Tree stumps
  • Nursery pots

When you feed your organic waste to our digester, we all benefit. 

If organic waste is disposed of in landfills, it can create methane gas, which is a greenhouse gas that is 25 times worse than CO2 and significantly contributes towards global warming.

When organic waste goes to our recycling facility instead, we all help by:  

  • reducing the carbon footprint of our community
  • diverting organic waste from landfills
  • creating enough energy to power 600 homes for a year

Waste Facts

Organic waste accounts for more than a third of California’s waste stream. Now, thanks to the partnership and actions of key participants, the San Luis Obispo County Organics Recycling System is now operating in a sustainable way at the Kompogas SLO Recycling Center.

Benefits of Kompogas SLO Organic Waste Recycling System

  • Local organic waste is recycled locally, not going to the landfill, and is extending the life of area landfills 
  • System contributes to California’s reduction in greenhouse gas emissions
  • The Dry Anaerobic Digestion plant generates renewable electricity
  • The Dry Anaerobic Digestion plant produces compost and liquid soil amendments for growers
  • Production of the renewable fuel biogas and compost as a byproduct will further enable the ecologically sustainable and profitable recycling of organic waste as a resource
  • System contributes to California’s goal of 75 percent reduction of organics from landfill by 2025
  • System contributes to SLO IWMA Regional Strategy to Meet California Solid Waste Diversion Mandates

With $4 million awarded and administered by CalRecycle, The Kompogas SLO Facility is part of California Climate Investments, a statewide program that puts billions of Cap-and-Trade dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment — particularly in disadvantaged communities. The California Energy Commission has provided an additional $4 million for development under the Electric Program Investment Charge (EPIC) Program.

In November 2018, our state-of-the-art, high heat, dry anaerobic digestion facility started converting organic waste into carbon-neutral biogas and high-grade natural compost.

Zurich-based Hitachi Zosen Inova (HZI) designed, financed, built, owns and operates the plant. HZI is a global leader in energy and material from waste solutions.
