Never Put These Things in Your Compost Bin


Composting is a great way to reduce waste and create nutrient-rich soil for your garden. However, not everything can be thrown into your compost bin. Certain items can disrupt the composting process, attract pests, or even contaminate the final product. In this article, we will discuss the top things that you should never put in your compost bin in 2023.

1. Meat and Dairy Products

While fruits, vegetables, and yard waste are great for composting, meat and dairy products should never be added to your compost bin. They can attract rodents, raccoons, and other unwanted pests. Additionally, they take longer to break down and can create unpleasant odors.

2. Oily Foods

Greasy or oily foods, such as salad dressings or cooking oils, should also be avoided in your compost bin. These substances can create a barrier that prevents air from reaching the compost, leading to anaerobic conditions and unpleasant smells. It’s best to dispose of these items in your regular trash instead.

3. Diseased Plants

If you have plants in your garden that are diseased or infested with pests, it’s best not to add them to your compost bin. The composting process may not kill the pathogens or pests, and you risk spreading them to your other plants when you use the compost in your garden.

4. Weeds with Mature Seeds

Weeds are a common addition to compost bins, but be cautious when adding them. Weeds that have already produced seeds can survive the composting process and germinate when you use the finished compost. Make sure to remove any mature seeds before adding weeds to your bin.

5. Pet Waste

Although organic in nature, pet waste should never be included in your compost bin. It can contain harmful bacteria and parasites that may not be killed during the composting process. Instead, dispose of pet waste in a separate designated area or use biodegradable pet waste bags.

6. Synthetic Materials

Avoid putting synthetic materials like plastic, rubber, or metal in your compost bin. These items do not break down and can contaminate the compost. Stick to organic materials like food scraps, yard waste, and paper products.

7. Ashes from Charcoal or Coal

While wood ashes can be beneficial for composting, ashes from charcoal or coal should be avoided. They can contain chemicals and toxins that are harmful to plants and soil. Only use wood ashes in moderation and avoid adding them if you’re unsure about their source.

8. Glossy or Colored Paper

While newspaper and plain cardboard are great additions to compost, glossy or colored paper should be kept out. These papers are often treated with chemicals and can take longer to break down. Stick to unbleached and uncoated paper products for composting.

9. Invasive Plants

If you’re dealing with invasive plants in your garden, it’s best not to include them in your compost bin. Even after the composting process, some seeds or plant parts may survive and spread when you use the compost. It’s better to dispose of invasive plants separately.


Composting is a sustainable way to reduce waste and create nutrient-rich soil for your garden. However, it’s important to be aware of what you put in your compost bin. By avoiding meat and dairy products, oily foods, diseased plants, weeds with mature seeds, pet waste, synthetic materials, ashes from charcoal or coal, glossy or colored paper, and invasive plants, you can ensure a successful composting process and a high-quality end product.
