Composting is a process that transforms organic waste into nutrient-rich compost, enhancing soil quality and promoting healthy plant growth. This transformation is driven by microorganisms, such as bacteria and fungi, in the presence of oxygen and moisture. Composting is a sustainable way to manage waste and reduce the amount of trash sent to landfills.

Composting at home can contribute to a greener lifestyle and positively impact the environment. In this article, we’ll explore some common household items that you can safely compost to enrich the top layer of the soil in your garden or compost pile. 

What is Composting and How Does it Work?

Understanding the Composting Process

A lot of our trash is made up of things that come from plants and animals, like food scraps, leaves, and more. Instead of throwing these things away, we can turn them into something good for the soil by composting.

Composting is like nature’s recycling system. It’s the way stuff from plants and the kitchen breaks down naturally. When you compost, food scraps, leaves, and old plant parts turn into a special dirt called compost. Microscopic creatures, like bacteria and fungi, help by eating the stuff and turning it into simpler things.

Imagine your compost pile or bin as a big salad with brown leaves, green veggies, and a little sprinkle of water and air. Over time, it all mixes and turns into fantastic compost you can use in your garden. 

To make compost, you need to mix things with lots of carbon (like dry leaves or cardboard, the “browns”) and things with lots of nitrogen (like food scraps or fresh grass, the “greens”). You also need to keep it airy and moist.

The Benefits of Composting

Composting offers many advantages for both the environment and your garden:

  • Reduces Greenhouse Gases: Composting diverts organic waste from landfills, which helps decrease the release of harmful greenhouse gases, like methane, that contribute to climate change.
  • Decreases Chemical Use: Compost provides essential nutrients to the soil and encourages healthy soil microorganisms, reducing the need for chemical fertilizers and pesticides.
  • Improves Soil Quality: Compost enhances soil structure, increases water retention, and improves drainage, resulting in healthier plants and higher yields.

Starting a compost pile at home is relatively easy, and you can compost a wide range of organic materials. Here are some steps to get you started:

  1. Choose a suitable location for your compost pile or bin. It should be well-drained and easily accessible.
  2. Select a compost bin that suits your needs. There are various options, including open bins, enclosed bins, and tumblers. Make sure the bin allows for proper aeration and drainage.
  3. Add a “brown” layer to the compost bin’s bottom. This could include dried leaves, straw, or shredded newspaper. Aim for a ratio of roughly three parts “browns” to one part “greens.”
  4. Add your “green” materials, such as fruit and vegetable scraps, coffee grounds, and grass clippings, to the “brown” layer.
  5. Continue layering “browns” and “greens” materials, making sure to mix them as you go. This will promote the breakdown of the organic matter and speed up the composting process.
  6. Keep the compost moist, like a damp sponge, by watering it regularly. This will help the microorganisms thrive and facilitate decomposition.
  7. Avoid adding dairy products, meat, or oily food scraps to your compost pile, as these can attract pests and slow down the composting process.
  8. Turn the compost pile with a pitchfork or shovel every few weeks to aerate it and promote even decomposition. This will also help speed up the composting process.
  9. the organic materials will break down into dark, crumbly compost after several months. This indicates that it is ready to be used in your garden.

What Can be Composted in a Home Composting Bin?

By knowing which materials are suitable for your home composting bin, you can not only divert organic waste from landfills but also produce valuable compost to enrich your potting soil.
