Introduction

Looking for a smart and eco-friendly way to reduce kitchen waste and help your garden thrive? You’re in the right place! In this blog post, we’re diving into a fun and practical project: Homemade compost bin DIY.

Making your own compost bin at home is easier than you might think — and you don’t need any fancy tools or expensive materials. Whether you live in a house with a backyard or an apartment with a balcony, you can start composting today. It’s a great way to recycle food scraps, improve your soil, and do your part for the environment.

What is Homemade Compost Bin DIY?

Homemade compost bin DIY is a do-it-yourself method of creating your own compost bin using simple materials you probably already have at home. Instead of buying a store-bought compost system, you build one yourself — usually with items like a plastic bin, bucket, or wooden box.

The goal is to create a space where food scraps, yard waste, and other natural materials can break down over time and turn into rich, healthy compost. This compost can then be used to feed your plants, flowers, or garden — completely free and chemical-free.

It’s a budget-friendly, beginner-friendly way to start composting, and it’s perfect for anyone who wants to live more sustainably without spending a lot of money.

Step-by-Step Guide: Homemade Compost Bin DIY (June 2025)

Creating your own compost bin is a practical and sustainable way to manage kitchen and garden waste. With just a few household materials and a little effort, you can start producing rich, organic compost to nourish your plants and reduce landfill waste.

What You’ll Need

1 plastic storage bin with a tight-fitting lid (18–30 gallons)
A drill or screwdriver
Bricks or wood blocks (for elevation)
Dry leaves, shredded newspaper, or cardboard (carbon source)
Kitchen scraps (vegetable peels, fruit waste, coffee grounds)
Garden waste (twigs, grass clippings, a small amount of soil)

Step 1: Choose a Suitable Container

Select a sturdy plastic bin with a lid. A dark-colored bin is ideal, as it absorbs heat and speeds up the composting process. Choose a size based on your household’s waste volume—18 to 30 gallons works well for most households.

Step 2: Drill Ventilation Holes

Use a drill or screwdriver to create ventilation and drainage:

Drill 10–15 holes in the lid for airflow.
Drill 6–10 holes on each side of the bin to allow oxygen in.
Drill 6–8 holes in the bottom for drainage to prevent waterlogging.

Proper airflow and drainage help prevent bad odors and support decomposition.

Step 3: Elevate the Bin

Place the bin on bricks, wooden blocks, or plant pot stands to lift it off the ground. Elevating the bin promotes air circulation and allows excess moisture to drain out from the bottom.

Step 4: Create a Carbon-Rich Base Layer

Add a few inches of shredded newspaper, cardboard, or dry leaves at the bottom of the bin. This layer helps absorb excess moisture and provides essential carbon for balanced composting.

Step 5: Add Kitchen and Garden Waste

Start adding your waste in alternating layers:

Greens (nitrogen-rich): Fruit and vegetable scraps, coffee grounds, tea bags
Browns (carbon-rich): Dry leaves, paper, cardboard, straw

Maintain a 3:1 ratio of browns to greens to keep the compost balanced and odor-free.

Step 6: Mix and Maintain the Compost

Every 3 to 5 days:

Stir or turn the compost with a stick or garden fork to introduce oxygen.
Check moisture levels—compost should be damp but not soggy.
Add more browns if the mix is too wet, or sprinkle water if it’s too dry.

Regular mixing helps speed up decomposition and prevents unpleasant smells.

Step 7: Keep Adding Material

Continue to add waste regularly. Cut large pieces into smaller bits to accelerate breakdown. Always cover fresh food waste with a layer of browns to deter pests and control odor.

Step 8: Monitor the Process

Over time (typically 4 to 8 weeks):

The pile will shrink in volume.
The material will darken and become crumbly.
You’ll notice a rich, earthy smell.

This indicates your compost is nearly ready.

Step 9: Harvest the Compost

When the compost is fully broken down:

Scoop out the finished compost for your garden or potted plants.
Sift out any larger pieces and return them to the bin for further decomposition.

Advantages and Disadvantages of a Homemade Compost Bin

Creating a compost bin at home is an effective way to manage organic waste and support a more sustainable lifestyle. However, like any DIY project, it comes with its pros and cons.

Advantages	Disadvantages
Cost-Effective Homemade compost bins can be built using inexpensive or recycled materials like old storage bins, buckets, or crates—eliminating the need to purchase commercial compost systems.	Time and Maintenance Required Homemade compost bins require regular attention—turning, moisture checks, and monitoring for balance. Neglect can lead to odors or pests.
Reduces Household Waste A large portion of kitchen and yard waste is compostable. Composting helps divert this waste from landfills, reducing overall garbage output.	Slower Decomposition Without insulation or aeration features found in commercial bins, decomposition in homemade bins may take longer, especially in cooler climates.
Improves Soil Health Homemade compost enriches soil with nutrients, improves structure, and enhances moisture retention—ideal for gardens, lawns, and potted plants.	Odor and Pest Risk If not properly managed, compost can emit unpleasant smells or attract insects and rodents, particularly in urban or small-space settings.
Environmentally Friendly Composting reduces methane emissions from landfills and lowers your carbon footprint, making it a simple yet powerful climate action.	Limited Volume Most DIY bins are small or medium-sized, which may not accommodate large volumes of waste or support large-scale gardening needs.
Customizable You can design and size the bin to suit your space, whether you live in an apartment, townhouse, or rural area.	Aesthetic Concerns Homemade compost bins might not look as tidy or appealing as store-bought ones, especially if placed in a visible area like a balcony or patio.
