Why Should You Start Home Composting? The Benefits of Composting

Beyond the satisfaction of diverting waste from landfills, home composting offers a wealth of benefits, both for you and the environment. Understanding these advantages will fuel your motivation and make the process even more rewarding.

Environmental Benefits

• Reduces Landfill Waste: A significant portion of household waste consists of organic materials that can be composted. By home composting, you significantly reduce the amount of trash sent to landfills, where it decomposes anaerobically (without oxygen) and releases harmful greenhouse gases like methane.
• Lowers Greenhouse Gas Emissions: As mentioned, landfills produce methane. Home composting, when done correctly, promotes aerobic decomposition, which minimizes methane production. Furthermore, you reduce the emissions associated with transporting waste to landfills.
• Conserves Water: Compost-amended soil retains moisture better, reducing the need for frequent watering. This is particularly beneficial in drought-prone areas.
• Reduces the Need for Chemical Fertilizers: Compost is a natural fertilizer that provides essential nutrients to plants. By using compost, you can reduce or eliminate the need for synthetic fertilizers, which can pollute waterways and harm beneficial soil organisms.

Benefits for Your Garden

• Enriches the Soil: Compost improves soil structure, aeration, and drainage. It helps sandy soils retain water and clay soils drain better.
• Provides Essential Nutrients: Compost is a slow-release fertilizer, providing plants with a steady supply of nutrients over time. It contains essential macronutrients like nitrogen, phosphorus, and potassium, as well as micronutrients that are vital for plant health.
• Suppresses Plant Diseases: Compost contains beneficial microorganisms that can help suppress plant diseases and protect plants from harmful pathogens.
• Improves Plant Growth: Healthy soil leads to healthy plants. Compost promotes strong root growth, vigorous foliage, and increased yields.

Personal Benefits

• Saves Money: By creating your own compost, you can reduce your reliance on expensive fertilizers and soil amendments.
• Reduces Your Carbon Footprint: Home composting is a simple yet effective way to reduce your environmental impact.
• Connects You with Nature: The process of home composting can be a rewarding way to connect with nature and appreciate the cycle of life.
• It’s Educational: Learn about decomposition, soil science, and the interconnectedness of ecosystems.

Choosing the Right Home Composting Method for You

Several home composting methods cater to different lifestyles, space constraints, and commitment levels. Consider your available space, the amount of waste you generate, and the time you’re willing to dedicate to the process when choosing a method.

Backyard Composting (Pile or Bin)

This is the most traditional method, suitable for those with a yard or garden. You can create a simple compost pile or use a commercially available compost bin. It typically involves layering “brown” and “green” materials.

Setting Up a Backyard Compost Pile or Bin

1. Choose a Location: Select a well-drained area that is easily accessible and receives partial sunlight. Avoid areas near water sources or sensitive areas.
2. Build or Purchase a Bin: You can build a simple compost bin using wood, chicken wire, or plastic pallets. Alternatively, you can purchase a commercially available bin, which may offer features like aeration and insulation. Consider a tumbling composter for faster results.
3. Start with a Layer of Browns: Begin with a layer of coarse “brown” materials, such as twigs, branches, or shredded cardboard, to provide aeration and drainage.
4. Add Greens and Browns in Layers: Alternate layers of “green” and “brown” materials, ensuring that the materials are mixed well.

Vermicomposting (Worm Composting)

Vermicomposting uses worms to break down organic waste. It’s an excellent option for those with limited space, such as apartment dwellers. Worms rapidly decompose food scraps, producing nutrient-rich castings (worm poop) that are highly beneficial for plants.

Setting Up a Vermicomposting System

1. Choose a Worm Bin: Purchase a commercially available worm bin or build your own using plastic bins. Ensure the bin has drainage holes and a lid. Many online tutorials show you how to build a simple system.
2. Add Bedding: Provide a suitable bedding material for the worms, such as shredded newspaper, coconut coir, or peat moss. Moisten the bedding thoroughly.
3. Introduce the Worms: Purchase red wiggler worms (Eisenia fetida) from a reputable supplier. Add the worms to the bedding and allow them to acclimate for a few days before adding food scraps.
4. Feed the Worms: Feed the worms a variety of food scraps, such as fruit and vegetable peels, coffee grounds, and tea bags. Avoid feeding them meat, dairy, or oily foods.

Bokashi Composting

Bokashi composting is an anaerobic (without oxygen) fermentation process that uses inoculated bran to pickle food waste. It’s excellent for handling all types of food waste, including meat and dairy, which are typically avoided in other composting methods. After fermentation, the pickled waste is buried in the garden or added to a traditional compost pile to fully decompose.

Setting Up a Bokashi System

1. Obtain a Bokashi Bucket: Purchase a Bokashi bucket with a tight-fitting lid and a spigot to drain excess liquid. These are readily available online.
2. Add Food Waste: Add food waste to the bucket, layering it with Bokashi bran. Press down firmly to remove air pockets.
3. Drain the Liquid: Drain the liquid (Bokashi tea) every few days. This liquid can be diluted and used as a fertilizer.
4. Bury the Fermented Waste: After the bucket is full and has fermented for at least two weeks, bury the pickled waste in the garden or add it to a traditional compost pile.

What to Compost: The Dos and Don’ts of Home Composting

Understanding what materials are suitable for home composting is crucial for a successful and odor-free operation. Generally, materials are categorized as “greens” (nitrogen-rich) and “browns” (carbon-rich).

“Greens” (Nitrogen-Rich Materials)

• Fruit and Vegetable Scraps: Peels, cores, stems, and other scraps.
• Coffee Grounds and Tea Bags: A great source of nitrogen and beneficial microbes.
• Grass Clippings: Use sparingly and mix well with browns to avoid compaction and odor.
• Plant Trimmings: Non-diseased plant material.
• Manure: From herbivores like cows, horses, and chickens (avoid pet waste).

“Browns” (Carbon-Rich Materials)

• Dried Leaves: An excellent source of carbon and helps to aerate the compost pile.
• Shredded Paper and Cardboard: Avoid glossy or colored paper.
• Twigs and Branches: Chop or shred them into smaller pieces to speed up decomposition.
• Sawdust: Use sparingly, as it can compact the pile.
• Straw: A good source of carbon and helps to retain moisture.

What Not to Compost

• Meat and Dairy Products (Except in Bokashi): These attract pests and can create foul odors.
• Oily Foods: Can disrupt the composting process and attract pests.
• Diseased Plants: Can spread diseases to your garden.
• Weeds with Seeds: The seeds may survive the composting process and sprout in your garden.
• Pet Waste: Can contain harmful pathogens.
• Chemically Treated Wood: Can leach harmful chemicals into the compost.

Maintaining Your Home Composting System

Maintaining a healthy home composting system involves regular monitoring and adjustments to ensure optimal decomposition. The key factors to consider are moisture, aeration, and the carbon-to-nitrogen ratio.

Moisture

The compost pile should be moist, but not soggy. It should feel like a wrung-out sponge. If the pile is too dry, add water. If it’s too wet, add more “brown” materials.

Aeration

Compost needs oxygen to decompose properly. Turn the pile regularly (every few days or once a week) to aerate it. This can be done with a pitchfork, shovel, or compost turner. Tumbling composters make aeration easy.

Carbon-to-Nitrogen Ratio

The ideal carbon-to-nitrogen ratio for home composting is around 25:1 to 30:1. This means you should have approximately 25 to 30 parts carbon-rich materials for every one part nitrogen-rich material. If the pile is not decomposing properly, adjust the ratio by adding more of either “greens” or “browns.”

Troubleshooting Common Composting Problems

Even with careful planning and maintenance, you may encounter some common composting problems. Here’s how to troubleshoot them:

Odor

Problem: Foul odors, such as ammonia or rotten egg smell.
Solution: This indicates anaerobic conditions. Turn the pile more frequently to aerate it. Add more “brown” materials to absorb excess moisture. Avoid adding meat, dairy, or oily foods.

Slow Decomposition

Problem: The compost pile is not decomposing quickly enough.
Solution: Ensure the pile is moist but not soggy. Turn the pile regularly to aerate it. Check the carbon-to-nitrogen ratio and adjust as needed. Make sure the materials are chopped into smaller pieces.

Pests

Problem: Attracting pests, such as flies, rodents, or raccoons.
Solution: Avoid composting meat, dairy, or oily foods. Bury food scraps deeply in the pile. Use a tightly sealed compost bin. Consider using a Bokashi system to pre-treat food waste before adding it to the compost pile.

Compost Too Wet

Problem: The compost is too wet and slimy.
Solution: Add more brown materials such as shredded paper or dried leaves. Turn the pile more frequently to improve aeration and allow excess moisture to evaporate.

Using Your Home Compost

Once your compost is finished, it’s time to reap the rewards and use it in your garden! Finished compost should be dark brown, crumbly, and have a pleasant earthy smell. Here are some ways to use your home composting creation:

• Soil Amendment: Mix compost into garden beds before planting to improve soil structure and fertility.
• Potting Mix: Use compost as part of your potting mix for containers and seedlings.
• Top Dressing: Spread a thin layer of compost around existing plants as a top dressing to provide nutrients and suppress weeds.
• Mulch: Use compost as mulch to retain moisture, suppress weeds, and regulate soil temperature.
• Compost Tea: Steep compost in water to create a nutrient-rich liquid fertilizer.
