What Can Be Added to Your Compost Bin

What Can Go in a Compost Bin: A Comprehensive Guide to Effective Composting

Welcome, eco-conscious enthusiasts and gardeners! In this blog post, we will dive into the world of composting and address the burning question: “What can go in a compost bin?” Whether you’re an experienced composter or just starting your journey towards sustainable living, this comprehensive guide will help you make informed choices when it comes to filling up that compost bin.

The Basics of Composting

Before we explore what items can be added to your compost bin, let’s quickly review the basics. Composting is a natural process that involves breaking down organic material into nutrient-rich soil. With proper maintenance and care, you can transform kitchen scraps and yard waste into valuable fertilizer for your garden.

Fruit and Vegetable Scraps

One of the most common types of material suitable for compost bins is fruit and vegetable scraps. These include discarded peels, cores, rinds, seeds (non-hybrid only), and any other parts not used during meal preparation. Remember to chop them into smaller pieces before adding them to your compost bin to speed up decomposition.


  • Avoid including citrus fruits as they take longer to break down due to their high acidity levels.
  • Steer clear from using diseased plant materials or those treated with pesticides/herbicides as they may harm beneficial organisms in your compost pile.

Coffee Grounds & Tea Bags

Your morning coffee routine can also contribute positively to your compost bin! Coffee grounds are rich in nitrogen — an essential element for successful decomposition. Similarly, tea bags made from biodegradable materials like paper or jute can be tossed into the mix. However, be sure to remove any staples or adhesive tags before composting them.


If you’re concerned about pH levels in your soil, remember that coffee grounds are slightly acidic. Therefore, ensure a balanced mix of other materials to maintain an optimal pH for your compost.


Don’t toss those eggshells into the trash! They make great additions to your compost bin. Eggshells provide calcium and help balance acidity levels in the soil as they break down. Crush them before adding them to speed up decomposition and deter critters from taking an interest in your compost pile.

Garden Waste

If you have a green thumb, there’s good news – garden waste is ideal for composting! Prunings, leaves, grass clippings (in moderation), small branches (chopped), and dead plants can turn into nutrient-rich humus when added to the compost pile. It’s crucial to create a balance between “green” nitrogen-rich materials like fresh grass clippings and “brown” carbon-rich materials like dry leaves for optimal decomposition results.

Paper Products

Yes, certain paper products can join the party too! Shredded newspaper without colored ink or glossy pages is an excellent choice for composting since it adds carbon content while aiding moisture retention. Additionally, cardboard cut into smaller pieces can also be added but avoid using wax-coated or plastic-lined varieties.

Avoid These Items!

While it may seem tempting to throw everything organic into your compost bin, some items should be kept out:

  • Meat and dairy products: These attract pests due to their high protein content and slow down decomposition processes significantly.
  • Oily or greasy food scraps: Fats can create unpleasant odors and attract unwanted critters.
  • Coal ash or pet waste: These contain harmful chemicals that can pollute the soil.

In Conclusion

Now that you’re well-versed in what can go in a compost bin, it’s time to put this knowledge into practice! Remember to maintain a good balance between “green” and “brown” materials while avoiding anything detrimental to your compost pile. With dedication and patience, you’ll soon be rewarded with dark, crumbly compost — the perfect foundation for healthy plants and sustainable gardening practices.

Happy composting!
