What to Put in Your Compost Bin: The Ultimate Guide for Organic Waste

What Goes in a Compost Bin: A Comprehensive Guide


Composting is an environmentally friendly practice that turns organic waste into nutrient-rich soil, reducing the amount of waste that ends up in landfills. If you’re new to composting or want to enhance your composting skills, it’s crucial to understand what items can be added to a compost bin and which ones should be avoided. In this blog post, we’ll provide you with a detailed breakdown of what goes in a compost bin.

Green Ingredients for Your Compost Bin

Fruits and Vegetables Scraps

One of the vital components for a healthy compost pile is food scraps from fruits and vegetables. Include peels, cores, leaves, stems, and any unused parts of these plant-based foods. However, remember not to add cooked food or oily residues as they may attract unwanted pests.

Coffee Grounds and Tea Bags

Coffee grounds are rich in nitrogen and make an excellent addition to your compost bin. Tea bags made from natural materials like paper or silk can also be included. Avoid using tea bags that contain staples or are made from synthetic materials.

Garden Trimmings

When pruning plants or mowing your lawn, collect the clippings for your compost pile. These green materials contribute valuable nutrients while improving airflow throughout the pile.


Rinse out eggshells thoroughly before adding them to your compost bin. They provide calcium carbonate which helps maintain pH balance in the final product.

Brown Ingredients for Your Compost Bin

Dry Leaves

Fallen leaves are abundant during autumn; collecting them not only keeps your garden neat but also provides an excellent source of carbon-rich material for your compost bin.

Straw and Hay

Straw or hay can be used to balance out the moisture levels in your compost pile. However, ensure it is free from seeds to prevent unwanted plants from sprouting in your garden later.

Newspaper and Cardboard

Shredded newspaper or cardboard acts as a carbon-rich “brown” ingredient that helps maintain proper moisture levels in the compost bin. Avoid using glossy or plastic-coated paper materials.

Avoid These Items

Meat and Dairy Products

Avoid adding meat, fish, bones, dairy products, or oily foods to your compost bin as they may attract pests and create unpleasant odors.

Invasive Weeds and Diseased Plants

Weeds with mature seeds or invasive roots should not go into your compost pile since they might survive the decomposition process. Additionally, avoid including diseased plants as this could spread harmful pathogens back into your garden upon use.

Composting Tips for Success

– Maintain a balanced mix of green (nitrogen-rich) and brown (carbon-rich) ingredients.
– Chop large items into smaller pieces to accelerate decomposition.
– Turn the pile regularly to aerate it and speed up breakdown.
– Keep the compost moist but not soggy; aim for the consistency of a wrung-out sponge.
– Add finished compost gradually to flower beds or vegetable gardens throughout the year.


By understanding what goes in a compost bin, you can create nutrient-dense soil amendments while minimizing waste. Remember to include fruit/vegetable scraps, coffee grounds, dry leaves, straw/hay, eggshells along with other appropriate materials while avoiding meat/dairy products and invasive weeds. With these guidelines in mind and regular maintenance practices like turning your pile occasionally and maintaining the right moisture levels, you’ll be well on your way to producing black gold for your garden!
