Basics of Composting
Composting is a natural process that transforms organic waste into nutrient-rich soil. It plays a vital role in reducing landfill waste and improving soil health. Understanding the fundamentals of composting can help Los Angeles residents contribute to a more sustainable city.
What is Composting?
Composting is the controlled decomposition of organic materials. It involves breaking down kitchen scraps, yard trimmings, and other biodegradable items into a dark, crumbly substance called compost. This process requires a balance of carbon-rich “browns” (like dry leaves) and nitrogen-rich “greens” (such as food scraps).
Microorganisms, including bacteria and fungi, drive the decomposition process. They thrive in warm, moist environments with adequate oxygen. A well-maintained compost pile reaches temperatures between 120-160°F, which helps kill weed seeds and pathogens.
Composting can be done in various ways, from simple backyard piles to more advanced bin systems or tumblers. The method chosen often depends on available space and the volume of compostable materials generated.
Benefits of Composting for Soil and Climate
Compost enhances soil structure and fertility, making it an invaluable resource for gardeners and farmers. It improves soil’s water retention capacity, reducing irrigation needs. Compost also introduces beneficial microorganisms that support plant health and root development.
From a climate perspective, composting helps mitigate greenhouse gas emissions. When organic waste decomposes in landfills, it produces methane, a potent greenhouse gas. Composting diverts this waste, reducing methane emissions.
In Los Angeles, composting aligns with the city’s sustainability goals. It supports local agriculture, reduces the need for chemical fertilizers, and helps combat soil erosion – a significant issue in Southern California’s arid climate.
Different Types of Compostable Material
Compostable materials fall into two main categories: greens and browns. Greens are nitrogen-rich and include:
- Fruit and vegetable scraps
- Coffee grounds and tea bags
- Fresh grass clippings
- Plant trimmings
Browns are carbon-rich materials such as:
- Dry leaves
- Shredded paper and cardboard
- Wood chips
- Straw or hay
Some items require special consideration. Meat, dairy, and oily foods should be avoided in home compost piles as they can attract pests. Diseased plants or weeds with seeds are best left out to prevent spreading issues to gardens.
Yard trimmings make excellent compost material. Los Angeles residents can compost fallen leaves, small twigs, and grass clippings from their yards.
Composting in Los Angeles
Los Angeles has made significant strides in promoting composting. The city launched its composting program in 2019, aiming to reduce organic waste in landfills.
Residents can participate by using green bins provided by the Bureau of Sanitation. These bins accept food scraps, yard trimmings, and other compostable materials.
The RecycLA program expanded composting services to businesses and multi-family properties. This initiative aligns with Senate Bill 1383, which mandates organic waste reduction across California.
Los Angeles offers various composting options:
- Curbside collection (green bins)
- Community compost hubs
- Farmers market drop-offs
- Backyard composting
The city provides educational resources and workshops to help residents compost effectively. These programs teach proper composting techniques and highlight the benefits of organic waste recycling.
Composting in Los Angeles helps:
- Reduce methane emissions from landfills

- Support local agriculture and green spaces
Los Angeles continues to expand its composting infrastructure. The city aims to increase participation and divert more organic waste from landfills, contributing to a more sustainable urban environment.
Home Composting Setup
Setting up a home composting system in Los Angeles is straightforward and rewarding. A well-designed setup reduces waste, creates nutrient-rich soil, and helps combat climate change by diverting organic matter from landfills.
Choosing the Right Composter
Selecting an appropriate composting bin is crucial for successful home composting. Options include:
- Tumbling bins: Easy to turn and aerate
- Stationary bins: Larger capacity, good for yards
- Worm bins: Ideal for apartments or small spaces
Consider factors like available space, amount of organic waste produced, and desired composting speed. For Los Angeles’ climate, choose a bin with proper ventilation and moisture control. Avoid compostable plastic containers, as they may not break down fully in home systems.
Setting Up Your Composting Bin
Place your composting bin in a convenient location with good drainage. Follow these steps:
- Choose a shady spot in your yard or balcony
- Ensure easy access for adding materials and harvesting compost
- Start with a layer of brown materials (leaves, cardboard) at the bottom
- Add a thin layer of soil to introduce beneficial microorganisms
- Keep a small kitchen pail near your prep area for collecting food scraps
Proper setup helps maintain the right balance of materials and facilitates efficient decomposition.
Maintaining the Compost Pile
Regular maintenance is key to successful composting:
- Balance green (nitrogen-rich) and brown (carbon-rich) materials
- Keep the pile moist but not soggy
- Turn the compost regularly to aerate and speed up decomposition
- Monitor temperature: a warm pile indicates active composting
Avoid adding meat, dairy, or oily foods to prevent odors and pests. In Los Angeles’ dry climate, water the pile periodically to maintain moisture. Well-maintained compost piles produce rich soil amendments in 3-6 months, reducing greenhouse gases and enriching gardens naturally.
What Can and Cannot Be Composted
Composting is an effective way to reduce waste and create nutrient-rich soil. Knowing which materials can be composted and which should be avoided is crucial for successful composting in Los Angeles.
Green Materials for Composting
Green materials are nitrogen-rich and provide essential nutrients for microorganisms in the compost pile. These include:
- Fruit and vegetable scraps
- Coffee grounds and filters
- Tea bags (remove staples)
- Eggshells (crushed)
- Grass clippings
- Fresh leaves and plant trimmings
These materials break down quickly and help maintain moisture in the compost. It’s best to chop larger items into smaller pieces to speed up decomposition.
Brown Materials for Composting
Brown materials are carbon-rich and provide energy for decomposers. They also help aerate the compost pile. Examples include:
- Dry leaves
- Straw or hay
- Sawdust (from untreated wood)
- Cardboard (torn into small pieces)
- Paper (without glossy coating or colored ink)
- Wood chips
- Dryer lint (from natural fibers)
These materials decompose more slowly than green materials. A good compost mix should have a balance of green and brown materials.
Non-Compostable Waste
Some items should never be added to compost bins:
- Meat, fish, and dairy products
- Oils and fats
- Diseased plants
- Weeds with seeds
- Pet waste (including dog poop)
- Treated wood products
- Plastic, glass, and metal
- Glossy paper or magazines
These materials can attract pests, create odors, or introduce harmful substances into the compost. They should be disposed of through appropriate waste management channels.
Community and Urban Composting
Los Angeles offers innovative solutions for composting in urban environments. Community-driven initiatives and accessible hubs make it easier for residents to participate in sustainable waste management practices.

Compost Use in Gardening
Compost plays a vital role in creating healthy, thriving gardens. It enriches soil structure and provides essential nutrients for plants, making it an excellent alternative to chemical fertilizers.
Enriching Your Soil with Compost
Compost improves soil structure by increasing its water retention capacity and enhancing drainage. It adds organic matter, promoting beneficial microbial activity and creating a more balanced ecosystem in your garden.
Mix compost into existing soil at a ratio of 1:3 (compost to soil) for best results. For new garden beds, spread a 2-3 inch layer of compost and work it into the top 6-8 inches of soil.
In container gardens, use a mix of 1 part compost to 3 parts potting soil. This combination provides nutrients and improves moisture retention in pots.
Compost as a Fertilizer Alternative
Compost serves as an excellent natural fertilizer, reducing the need for chemical alternatives. It releases nutrients slowly, providing a steady food source for plants throughout the growing season.
Apply a 1-2 inch layer of compost around established plants as a nutrient-rich mulch. This method, known as top-dressing, feeds plants while conserving soil moisture and suppressing weeds.
For vegetable gardens, incorporate compost into planting holes when transplanting seedlings. This gives young plants a nutrient boost and encourages strong root development.
Using compost as fertilizer lowers your garden’s carbon footprint and promotes sustainable gardening practices in Los Angeles.
Composting Laws and Regulations
California Senate Bill 1383 mandates statewide organic waste reduction to combat methane emissions. This law took effect in 2022, with enforcement beginning in 2024.
Los Angeles residents are now required to separate food scraps and other organic waste from regular trash. The city provides free compost pails to assist with this process.
Waste management companies must offer recycling services that include organic waste collection. This applies to both residential and commercial properties.
The law sets limits on the amount of finished compost that can be sold or given away from certain operations. Agricultural composting has specific exemptions under California Code of Regulations, Title 14.
Public agencies are tasked with education and outreach to ensure compliance. They must also implement inspection and enforcement programs.
