Composting is a natural process that transforms organic waste into nutrient-rich soil amendment.
Over 28% of household waste is organic material that can be composted instead of ending up in landfills.
Composting at home helps reduce waste and creates valuable fertilizer for your garden.
Leaves and grass clippings are essential “browns” and “greens” for effective composting¹.
Composting can improve soil health and water retention, making it a sustainable practice.

What is Composting?

Composting turns organic stuff like leaves, food scraps, and yard trimmings into a special soil booster called compost. This process uses tiny organisms, fungi, and more to break down these materials. It makes a great resource for gardens and farms².

Understanding the Composting Process

Composting mixes “greens” (like food scraps and grass clippings) with “browns” (such as leaves and paper). It also needs air and the right amount of moisture. As everything breaks down, tiny helpers release nutrients for the soil³.

Benefits of Composting

Composting has lots of perks. It cuts down on landfill waste, lowers methane emissions, boosts soil health, saves water, and reduces food waste. By taking organic stuff out of landfills, it also reduces methane, a strong greenhouse gas². Plus, the compost makes soil better for plants, helps it hold water, and supports healthy plant growth³.

Composting Benefits	Description
Waste Reduction	Keeps organic materials out of landfills, cutting down on waste.
Methane Emission Reduction	Stops methane, a strong greenhouse gas, by keeping organic waste out of landfills.
Soil Health Improvement	Compost adds nutrients to soil, making it better for plants and water.
Water Conservation	Compost helps soil keep moisture, so you don’t need to water as much.
Food Waste Reduction	Composting at home cuts down on food waste sent to landfills.

“Composting turns organic matter into a soil booster. It’s easy and good for the planet, helping your garden or landscape grow.”

Reducing Waste and Methane Emissions

Composting is a great way to recycle the organic waste we make at home. Food scraps and garden waste make up over 28% of what we throw away⁴. Sending this waste to landfills is expensive and makes methane, a strong greenhouse gas that traps heat in the atmosphere⁵. By composting at home, we can keep organic waste out of landfills and cut down on methane emissions.

Some cities, like San Francisco, have big composting programs. These programs help them keep over 80% of waste out of landfills⁴. Households that join these programs send 4.2 kilograms of waste to compost, which is 25% less than before⁴. Moving a ton of organic waste to compost can cut methane emissions by 6% to 26%⁴.

The U.S. government is working to reduce waste and methane emissions too. The USDA has given millions to research, grants, and programs to help with food donations, reduce food waste, and support organics recycling⁶. The Bipartisan Infrastructure Law also gave $83 million for organics recycling projects⁶.

Working on methane reduction is key to cutting greenhouse gas emissions by 50% by the end of the decade⁵. The Waste Methane Assessment Platform (WasteMAP) offers data and resources to help communities and industries lower waste methane emissions⁵.

Organic Waste Recycling

“Reducing methane emissions is one of the most effective strategies we have to slow the rate of global warming in the near term and keep 1.5°C in reach.”
– United Nations Environment Programme

By using composting and other zero-waste strategies, we can greatly reduce waste, lower methane emissions, and help create a sustainable future⁴⁶⁵.

Improving Soil Health and Water Conservation

Compost is a key tool for better soil health and saving water. It acts as a⁷ natural fertilizer, packed with nutrients like nitrogen, phosphorus, and potassium. Studies show that adding organic matter, like compost, boosts a soil’s ability to hold water⁸. This means more water for farmers with the same amount of land, leading to better crops⁸.

Compost as a Natural Fertilizer

Compost is a top choice for making soil healthier and more productive⁷. It’s better than synthetic fertilizers because it also improves soil structure and supports beneficial microbes⁹. By using compost, farmers can cut down on chemical fertilizers and make farming more sustainable⁹.

Water-Retaining Benefits of Compost

With water becoming scarcer, compost’s ability to hold water is a big plus for farming⁸. Soils with compost do better at absorbing water, losing less and holding more, helping plants survive dry spells and needing less water⁸. Adding compost to farms saves water and creates healthier, stronger soils⁸.

Benefit	Description
Nutrient-Rich	Compost is full of nutrients like nitrogen, phosphorus, and potassium, plus trace elements.
Soil Structure Improvement	Compost’s organic matter makes soil better at letting water in and air through.
Water Conservation	Soils with compost hold more water, so you need to water less often.
Microbial Diversity	Compost feeds a rich soil life, crucial for nutrient cycling and plant health.
Sustainable Farming	Using compost cuts down on synthetic chemicals, making farming more eco-friendly.

“Compost is a natural wonder that can transform the health and productivity of your soil, while also conserving precious water resources. It’s a win-win for farmers and the environment.”

By using compost, farmers can boost soil health, save water, and use fewer chemicals. This leads to farming that’s sustainable and strong⁷⁸⁹.

Organic Waste Recycling at Home

Even with our best efforts, some food scraps can’t be eaten. Composting is a great way to recycle these scraps instead of throwing them away. The NRDC says the average American family throws away about $150 worth of food each month. Fruits and vegetables are often the top items wasted¹⁰. By composting, we can keep these materials out of landfills and make valuable soil.

Minimizing Food Waste

Organic waste, like food scraps and yard waste, makes up a big part of our trash¹¹. Studies show it’s about 25% of what we throw away¹¹. Recycling organic waste helps us reduce trash and work towards zero waste goals¹¹. California’s SB 1383 aims to cut down on organic waste in landfills to fight climate change¹⁰.

The City of San Diego offers weekly Organic Waste Recycling for homes, with different bin sizes¹⁰. Businesses and apartments can get recycling bins from approved haulers or recyclers¹⁰. California wants to give 20% of extra food to those in need by 2025, thanks to SB 1383¹⁰.

Commercial Edible Food Generators	Tier One	Tier Two
Specific Criteria	Annual sales, facility size, number of seats/rooms	Annual sales, facility size, number of seats/rooms

By composting at home, we can cut down on food waste and make rich soil for our gardens. Composting at home is a simple yet impactful way to support a more sustainable future.¹¹

“Organic waste recycling can help reduce the amount of waste put in trash bins, moving closer to zero waste and climate action goals.”

Types of Home Composting

There are two main ways to compost at home: cold or passive composting and hot or active composting. Each method has its own benefits, fitting different lifestyles and needs¹².

Cold or Passive Composting

Cold composting, or passive composting, is easy and slow. It means just piling organic waste and letting it break down naturally. This process can take 6 months to a year to finish¹². It’s perfect for those with little waste or who like a simple composting method.

Hot or Active Composting

Hot composting is faster and needs more work. It requires balancing carbon and nitrogen levels, keeping air and moisture right for fast breakdown. With the right mix, a hot compost pile can be ready in 4 weeks to 12 months¹². This method is great for those with lots of waste and time to keep an eye on their compost.

Both cold composting and hot composting are great for recycling waste and making garden soil rich¹²¹³.

Composting Method	Time to Produce Compost	Maintenance Level	Ideal for
Cold (Passive) Composting	6 months to 1 year	Low	Limited organic waste, hands-off approach
Hot (Active) Composting	4 weeks to 12 months	High	Larger volumes of organic waste, active management

“Composting is an easy and effective way to reduce household waste and create nutrient-rich soil for your garden. Whether you choose cold or hot composting, the benefits of recycling organic matter are well worth the effort.”

Knowing the differences between cold composting and hot composting helps homeowners pick the best method for them. This choice supports a greener future¹²¹³.

Setting Up a Compost Bin

Starting to turn your organic waste into compost begins with the right setup. Pick a spot that’s dry, shaded, and easy to get to for upkeep¹⁴. You can buy a compost bin or make one with wire mesh and strong poles. It’s important to mix green (nitrogen-rich) and brown (carbon-rich) materials right. Also, keep it moist and airy for quick breakdown.

Choosing the Right Location

Think about easy access, shade, and being close to your kitchen or garden when picking a spot for your compost bin¹⁴. It should be dry and have good airflow, but not in direct sunlight to avoid drying out too fast. Having the bin near your garden or vegetable patch makes adding the finished compost easy.

Selecting a Composting Method

There are many composting methods, each with its own perks. Cold or passive composting is easy to manage, while hot or active composting needs more work but works faster¹⁴. Choose the method that fits your time, space, and goals for composting to have success with backyard composting.

“Composting is a remarkable process that transforms your organic waste into a nutrient-rich soil amendment. With the right setup and a bit of care, you can create a sustainable cycle of waste reduction and soil rejuvenation right in your own backyard.”

Composting Ingredients

Composting turns organic waste into nutrient-rich soil for gardens. It’s all about the right mix of compost ingredients. You need nitrogen, carbon, air, and water for it to work well¹⁵.

“Greens” for Nitrogen

“Greens” like fresh grass clippings, food scraps, and coffee grounds add nitrogen-rich materials to the compost. These help the decomposition process and feed good microorganisms¹⁶.

“Browns” for Carbon

“Browns” include dead leaves, branches, twigs, and paper. They add carbon-rich materials to the mix. These “browns” give energy to microorganisms, helping them break down the waste. Aim for a compost ratio of 30:1 carbon to nitrogen for best results¹⁵¹⁶.

Nitrogen-Rich “Greens”	Carbon-Rich “Browns”
Fruit and vegetable scraps Grass clippings Coffee grounds Eggshells Tea bags	Dry leaves Shredded newspaper Cardboard Sawdust Straw

Knowing about compost ingredients helps gardeners make a great compost pile. It turns waste into a soil booster¹⁵¹⁶.

Maintaining the Compost Pile

Creating a successful compost pile needs careful compost maintenance. It’s key to keep an eye on the carbon-to-nitrogen ratio and air and moisture levels in the pile¹⁷.

Achieving the Ideal Carbon-Nitrogen Ratio

The perfect carbon-to-nitrogen ratio for compost is between 25:1 and 30:1. Too much carbon makes the pile dry and slow to break down. Too much nitrogen makes it wet, smelly, and fast to break down. Turning the pile often and adding water helps keep it right for composting¹⁷.

Monitoring Air and Moisture Levels

Good air flow and moisture are key for compost troubleshooting. The pile should be warm enough to kill harmful germs and break down materials well¹⁷. Keeping moisture between 40% and 60% helps the decomposers work best¹⁷. Turning the pile and adding water keeps it just right for composting¹⁷.

Compost Maintenance Factor	Optimal Range
Compost Pile Height	4 to 5 feet maximum, 3 1/2 feet minimum¹⁷
Temperature Range	Not specified but crucial for pathogen destruction and decomposition by thermophiles¹⁷
Composting Speed	Approximately 6 weeks under optimum conditions¹⁷
Moisture Percentage	40% to 60% balance, too dry or too wet conditions impact decomposition efficiency¹⁷
Volume Reduction	Approximately one-third of the original volume¹⁷
Compost Moisture Level	Similar to that of a wrung-out sponge to ensure proper hydration for decomposer organisms¹⁷

“Composting is a method of organics recycling that accelerates decomposition by creating an ideal environment for decomposing organisms to thrive, such as bacteria, fungi, earthworms, termites, and millipedes.”¹⁸

Vermicomposting: Using Worms

Vermicomposting uses worms to break down organic waste. It’s a green way to compost at home. Red wiggler worms are perfect for this, loving the moist, rich environment of a worm bin¹⁹. These worms can grow from 1,000 adults to 2,000–3,000 in a home bin¹⁹. They control their numbers based on space, moisture, and food¹⁹.

Setting Up a Worm Bin

To start vermicomposting, you need a bin with drainage and air holes, some moist bedding, and the worms. You can keep the bin inside or outside. It needs regular care to keep the worms happy and working¹⁹. Worms can make babies when two meet, and they need the right conditions to thrive¹⁹.

They do best in temperatures between 55 and 77 degrees Fahrenheit, with the right moisture and air¹⁹. Vermicomposting uses two earthworm types: Eisenia foetida and Lumbricus rubellis, which work well together¹⁹. The end product, vermicompost, is full of nutrients that help plants grow strong¹⁹.

“Vermicompost can increase plant growth and yield as well as suppress pests and diseases, proving its effectiveness in horticultural settings.”²⁰

It takes 3-6 months to make a lot of vermicompost, depending on the worms and what you feed them²⁰. Letting it cure for 8-10 weeks makes it better for plants²⁰. Vermicompost is full of nutrients and helps plants grow well²⁰.

Using vermicompost tea gives plants more nutrients and helps them grow²⁰. Aeration makes the tea work better, helping plants and fighting pests²⁰.

Worm Species	Effectiveness in Vermicomposting
Eisenia foetida	Highly effective
Lumbricus rubellis	Highly effective

With a worm bin, you can turn your waste into a great soil amendment for your garden¹⁹²⁰.

Organic Waste Recycling Tips

Composting is great, but there are more ways to recycle organic waste and help the planet. Starting big community composting programs can really help reduce waste²¹. Learning how to cut down on food waste, like with the NRDC’s “Save the Food” campaign, also makes a big difference²².

Trying to live a zero-waste life is another big step. This means setting up spots for collecting food scraps and yard waste to be turned into something useful²¹. By following these tips, you can really help the environment.

To cut down on waste even more, try composting food scraps at home or use a Kitchen Caddie to carry them to your compost bin²¹. These easy steps can help meet waste reduction goals, like California’s AB 1826 and SB 1383²¹.

Organic Waste Recycling Benefits	Key Metrics
Reduce methane emissions from landfills	SB 1383 aims to reduce organic waste landfill disposal by 75% by 2025 from 2014 levels, diverting over 20 million tons from landfills²².
Contribute to food waste reduction	20% of edible food in California needs to be recovered and given to those who don’t have enough food as part of the SB 1383 law²².
Improve soil health through composting	Home composting is a great way to reduce waste and lessen methane production, a strong greenhouse gas²².

By using these tips for organic waste recycling, you can really make a difference. You’ll help reduce your environmental impact and work towards a greener future²¹²².

“Composting is not just about reducing waste – it’s about creating a renewable resource that can enrich our soil and nourish our plants. It’s a simple, yet powerful, way to live more sustainably.”

Troubleshooting Common Composting Issues

Composting is great for reducing waste and making soil rich for your garden. But, even experts may face issues like bad smells or slow breakdown. There are steps to fix these problems and keep your compost pile healthy²³.

Getting the right mix of carbon and nitrogen is key to composting. Aim for 3 parts brown materials to 1 part green ones²³. Bad smells mean your mix might be off, so add more dry leaves or newspaper²³. If things are breaking down too slowly, add more green stuff like food scraps or grass clippings²³.

Keeping the right moisture is also important. Aim for it to be as damp as a wrung-out sponge²⁴. Too wet can cause bad smells and slow things down, while too dry slows it down too. Turn the compost often and adjust the moisture to keep it just right for the tiny helpers that break it down²⁴.

Some pests like fruit flies and pill bugs can be a problem. They’re drawn to too many kitchen scraps or a wet pile²⁴. Use a tarp or a lid on your bin to keep them out²⁴.

Fixing composting problems is about finding balance and making changes as needed. Keep an eye on your compost and fix any issues quickly. This way, you’ll get great compost that’s good for your garden and the planet²³²⁴.

“Composting is not just about reducing waste – it’s about creating a valuable resource for your garden. With a little troubleshooting, you can ensure your compost pile is working its magic to enrich your soil and reduce your environmental footprint.”
