Composting Tips: 13 Things Not to Compost

Composting Made Simple: What to Avoid and How to Use a Compost Tumbler

Composting is one of the most effective and eco-friendly ways to manage food waste, reduce landfill contributions, and nourish your garden with nutrient-rich soil. However, not all waste is suitable for composting, especially when using mechanical composting appliances like compost tumblers. To maximize your composting success and protect your equipment, it’s essential to know the 13 things not to compost and understand how to use a compost tumbler properly.

The 13 Things Not to Compost: Protect Your Compost and Your Machine

Augewei, a leader in sustainable kitchen appliances, emphasizes that certain materials should never enter your compost tumbler. Including these can damage your composting device or disrupt the composting process:

1. Large Bones: Tough and slow to break down, they can jam or damage blades.

2. Animal Shells: Like large crab or lobster shells—they are too hard for home composting systems.

3. Fruit Shells with Tough Rinds: Such as coconut shells, which take a very long time to decompose.

4. Plastics: Completely non-biodegradable, plastics contaminate compost and damage equipment.

5. Metal Items: Including foil and other metals that can cause mechanical failure or injury.

6. Oily Foods: Excess oils can create bad odors and hinder microbial activity.

7. Dairy Products: These attract pests and cause unpleasant smells.

8. Meat Scraps: Likely to generate odors and attract rodents; better avoided unless you have specialized composting systems.

9. Pet Waste: Contains harmful pathogens not suitable for compost.

10. Diseased Plants: Risk spreading disease when compost is used in gardens.

11. Glossy Paper: Often coated with chemicals that do not decompose well.

12. Synthetic Fabrics: Non-biodegradable and should never be composted.

13. Charcoal Ash: Contains toxic substances harmful to soil life.

Avoiding these materials helps maintain the integrity of your compost tumbler, prevents foul odors, and ensures the composting process proceeds smoothly.

How to Use a Compost Tumbler: Tips for Success

A compost tumbler is a convenient and efficient tool that speeds up decomposition by aerating the compost regularly through rotation. Here’s how to use it effectively:

• Balance Greens and Browns: Compost needs a proper mix of nitrogen-rich “greens” (fruit and vegetable scraps, coffee grounds) and carbon-rich “browns” (dry leaves, shredded paper, cardboard). Aim for roughly a 2:1 ratio of browns to greens to maintain a healthy microbial environment.

• Layering: Start your tumbler by adding a layer of browns, followed by a layer of greens. Alternate these layers as you add waste. This helps maintain aeration and moisture balance.

• Maintain Ideal Moisture: Compost should be as damp as a wrung-out sponge. Too much water causes anaerobic conditions and odor; too little slows down decomposition. Add water or dry material as needed.

• Rotate Regularly: Turn or rotate the tumbler every few days to aerate the pile. This supplies oxygen to microbes, speeds up breakdown, and prevents clumping.

• Temperature Monitoring: Composting generates heat as microbes work. A healthy compost tumbler will feel warm inside, indicating active decomposition.

• Avoid Overfilling: Don’t fill the tumbler beyond its capacity. Overfilling restricts airflow and slows the process.

• Use in a Suitable Location: Place your tumbler where it’s convenient but not obstructive. Partial sunlight helps maintain warmth, but avoid full, harsh sun exposure to prevent drying out.

Benefits of Proper Composting

When done right, composting transforms kitchen scraps and yard waste into nutrient-dense soil amendments. This enriches garden beds, promotes plant growth, and reduces the need for chemical fertilizers. Moreover, by diverting organic waste from landfills, you reduce methane emissions—a potent greenhouse gas—supporting a healthier planet.
