Discover Which Items are Compostable and Help Reduce Waste

What Items are Compostable: A Guide to Sustainable Waste Management

In recent years, there has been a growing emphasis on adopting sustainable practices to minimize our ecological footprint. One crucial aspect of this movement is composting. Composting allows us to transform organic waste into nutrient-rich soil, thereby diverting it from landfills and reducing greenhouse gas emissions. However, understanding which items can be composted can sometimes be confusing. In this blog post, we will provide you with a comprehensive guide on what items are compostable and how you can make the most out of your organic waste.

The Basics of Composting

Before delving into the specific items that can be composted, let’s briefly cover the basics of composting. Composting is a natural process where microorganisms break down organic matter into humus (a dark brown or black organic material). This process requires oxygen, water, and heat for optimal decomposition.

Fruit and Vegetable Scraps

If you’re wondering what to do with those leftover fruit peels or vegetable scraps after cooking a delicious meal – worry not! Fruit and vegetable scraps are excellent candidates for composting. This includes banana peels, apple cores, carrot tops, potato peelings – anything that comes directly from plant-based sources.


Eggshells are another common household item that is great for composting. Not only do they add valuable calcium to your pile but also help balance its pH levels. Be sure to crush them before adding them to speed up decomposition.

Coffee Grounds and Tea Bags

If you enjoy starting your day with a cup of coffee or tea, don’t throw away those used grounds or tea bags just yet! Coffee grounds contain beneficial minerals like nitrogen, while tea bags provide organic matter rich in tannins. Both coffee grounds and tea bags contribute to creating a nutrient-rich compost heap.

Paper Products

Did you know that many paper products can be composted instead of being tossed in the trash? Unbleached paper towels, newspaper clippings (without colored ink), cardboard, and shredded office paper are all examples of items that can break down naturally in a compost pile.

Napkins and Paper Plates

If you’ve hosted a party or have leftover napkins from takeout meals, fear not – these too can find new life as part of your composting efforts. However, do ensure they are made from unbleached materials without any plastic or wax coatings.

Brown Paper Bags

The next time you bring back groceries in brown paper bags, don’t just throw them away! Tear them into small pieces and add them to your compost bin. Brown paper bags decompose relatively quickly compared to other forms of packaging materials.

Yard Waste

In addition to kitchen scraps and paper products, yard waste is another substantial component suitable for composting. Grass clippings, leaves, branches (chopped into smaller pieces), bark chips, flowers – all these biodegradable materials make excellent additions to your outdoor composter.

Weeds (without seeds)

If you’ve spent hours battling weeds in your garden or backyard – put those pesky plants to good use by adding them to your compost pile. Just ensure that the weeds have been deprived of their reproductive capacity by removing their seeds beforehand!

Pruned Branches

After pruning trees or shrubs around your property, gather up the branches and cut them into smaller pieces. These pruned branches can provide a valuable source of carbon to balance the nitrogen-rich kitchen waste in your compost heap.

What Should NOT Be Composted

While it’s important to know what can be composted, it is equally crucial to understand which items should not be included in your compost pile:

Dairy Products and Meat

Avoid adding dairy products like milk, cheese, or yogurt, as well as meat scraps or bones to your compost bin. These items may attract pests and cause unpleasant odors.

Oily Foods

Fats, oils, and greasy foods should also be kept out of your compost bin. They decompose much more slowly than other organic materials and can disrupt the natural breakdown process.

Invasive Weeds with Seeds

Although weeds without seeds are suitable for composting, invasive weeds that have begun producing seed heads should not be added. Introducing these seeds into your garden through finished compost might lead to unwanted plants taking over!

The Benefits of Composting

Beyond reducing landfill waste and greenhouse gas emissions, there are several benefits associated with adopting a regular composting routine:

Nutrient-Rich Soil Amendment

The end product of successful decomposition – known as humus – makes an excellent soil amendment due to its high nutrient content. Adding this rich humus back into your garden beds boosts plant growth while improving the soil structure.

Water Retention Capability

The organic matter found in well-composted soil helps improve water retention capabilities by increasing its ability to absorb moisture effectively. This reduces the need for frequent watering while promoting healthier root systems for plants.

In conclusion

Composting is a simple yet rewarding way to contribute positively to the environment while nourishing your garden. By understanding what items are compostable, you can effectively reduce waste and create nutrient-rich soil for your plants. Remember, it’s always beneficial to do thorough research on composting methods and guidelines specific to your local area.
