What Not to Throw in a Compost Pile

Composting is an easy, effective way to recycle table scraps and other materials into rich, beneficial soil for your garden. Not only does this green practice help improve the growing environment for plants and vegetables, it can also help save on planting prep time.
While there are dozens of foods and materials that can be used for composting, not every food scrap can be added to your compost pile. Some items can attract rodents and other pests, others can deter the composting process and some can even be toxic. So what items should you not compost?
Here are some materials should definitely keep out of your compost pile:


Animal waste: Kitty litter and dog waste have contaminants that can be harmful to your soil.
Citrus peels: The acidity levels in citrus peels can slow down the composting process, and this can affect the maturity of the composted soil.
Diseased house plants: Throw dead, wilted plants in the garbage, as the fungus or bacteria that affected the plants can be transferred to your compost.
Meat products: This includes animal fat, bones and fish. Such items can attract larger rodents to your yard.
Milk products: Although dairy products such as cheese, milk and yogurt will break down, they also attract pests that can cause harm to our garden.
Tea and coffee bags: While adding coffee grounds and tea leaves to your compost adds a host of welcome nutrients - like potassium and nitrogen - to your soil, you cannot add their bags or filters to your compost. They are most likely made of synthetic fibers that are unable to break down.
These are just a handful of items you should not compost. When in doubt, contact your municipal waste management department for details about specific items.
