What is Composting?

Composting is the process of decomposing organic waste into nutrient-rich soil that can be used in gardens and landscaping. It involves breaking down food scraps, yard waste, and other organic matter in a controlled environment to create a fertile soil amendment that can benefit plants and the environment.

The benefits of composting are numerous. By diverting organic waste from landfills, composting helps reduce greenhouse gas emissions and prevents the buildup of methane gas. Additionally, compost can improve soil health by promoting good soil structure and providing essential nutrients to plants, leading to healthier and more bountiful gardens.

There are two main types of composting: backyard composting and home composting. Backyard composting involves using a bin or pile in a backyard or garden to create compost. Home composting, on the other hand, involves using a compost tumbler or other small-scale system inside a home or apartment. Both types of composting have their own benefits and challenges, depending on the needs and resources of the individual composter.

Compostable vs Non-Compostable: Understanding the Difference

One of the key aspects of successful composting is understanding the difference between compostable and non-compostable materials. Compostable materials are those that can break down into organic matter, which can be used to enrich soil. Non-compostable materials, on the other hand, are those that do not break down or can even harm the composting process.

Compostable items: Some common compostable items include fruit and vegetable scraps, coffee grounds, leaves, grass clippings, and eggshells. These materials are high in nitrogen and carbon, which are essential elements for healthy compost.

Non-compostable items: Certain items should never be added to a compost pile. These include meat, dairy products, oily foods, pet waste, and anything containing pesticides or chemicals. These materials can attract pests, emit foul odors, and slow down the decomposition process.

It’s important to note that some materials may be compostable in certain conditions or with additional processing. For example, paper products are generally compostable, but glossy or colored paper may contain chemicals that could be harmful to the compost. To ensure the safety and success of your composting process, it’s always best to research and double-check any materials you plan to include.

Don’ts

  • Don’t add meat, dairy, or oily foods: These items can attract pests and slow down the decomposition process. Stick to plant-based materials for your compost pile.
  • Avoid adding pet waste or diseased plants: These materials can introduce harmful bacteria to your compost and potentially spread disease to your garden.
  • Don’t add weeds or invasive plants: These plants can take root and spread in your garden, causing problems down the line.

By following these do’s and don’ts, you can create a healthy and productive compost pile that will benefit both your garden and the environment.

What Can be Composted?

Composting is a great way to reduce waste and create nutrient-rich soil for your plants. But what exactly can be added to a compost pile? Here are some common composting materials:

Composting Materials Examples
Brown materials Dry leaves, branches, twigs, sawdust, shredded paper, cardboard
Green materials Fruit and vegetable scraps, grass clippings, coffee grounds, eggshells, tea bags
Other organic materials Wood ash, hair, shredded newspaper, dryer lint, cotton and wool rags

It is important to note that larger materials, such as tree branches, should be chopped or shredded before adding them to the compost pile. Doing so will help them decompose more quickly and evenly.

Remember to avoid adding non-compostable materials, such as meat, dairy, oily foods, and pet waste, to your compost pile. These materials can attract pests and potentially harm the environment.

By including these composting materials in your pile, you can create a healthy, nutrient-rich soil that will support the growth of your plants and help reduce waste in your community.

What Can’t be Composted?

While there are many materials that can be added to a compost pile, there are also several items that should not be composted. Knowing what to avoid is just as important as knowing what to include, as adding the wrong materials can have negative consequences for both the compost pile and the environment. Here are some common materials that should not be composted:
