Can you use a compost tumbler for meat and dairy? While compost tumblers are excellent for managing kitchen scraps and garden waste, using them for meat and dairy is generally discouraged due to potential issues like odor, pests, and pathogens. However, with proper management, some advanced composters might successfully compost these materials.
Why Avoid Meat and Dairy in Compost Tumblers?
Composting meat and dairy in a compost tumbler can lead to several challenges:
- Odor: Meat and dairy can produce unpleasant smells as they decompose, which can be a nuisance in residential areas.
- Pests: These items attract pests like rodents and flies, which can become a problem if not managed properly.
- Pathogens: Meat and dairy can harbor harmful bacteria and pathogens, posing health risks if the compost doesn’t reach high enough temperatures to kill them.
Can You Compost Meat and Dairy Safely?
Despite the challenges, it is possible to compost meat and dairy with careful attention:
- High Temperatures: Ensure the compost reaches temperatures above 140°F (60°C) to effectively kill pathogens.
- Balance: Maintain a proper balance of green (nitrogen-rich) and brown (carbon-rich) materials to aid decomposition.
- Aeration: Regularly turn the compost to provide oxygen and prevent anaerobic conditions that cause odors.
Practical Tips for Composting Meat and Dairy
If you decide to compost meat and dairy, consider these tips:
- Small Pieces: Cut meat and dairy into small pieces to speed up decomposition.
- Layering: Layer with plenty of carbon-rich materials like leaves or wood chips to absorb odors and moisture.
- Compost Additives: Use compost accelerators or bokashi bran to enhance microbial activity and break down proteins faster.
Alternatives to Composting Meat and Dairy
For those unwilling to risk the challenges, consider these alternatives:
- Bokashi Composting: This method ferments food waste, including meat and dairy, using beneficial microbes in an anaerobic environment.
- Municipal Composting: Some cities offer composting services that accept meat and dairy, utilizing industrial processes to handle these materials safely.
- Pet Food: In some cases, leftover meat can be safely repurposed as pet food, reducing waste.

How often should you turn a compost tumbler?
For optimal results, turn your compost tumbler every 2-3 days. Regular turning introduces oxygen, which is essential for the aerobic bacteria that break down organic matter.
Can you compost bones in a tumbler?
Composting bones in a tumbler is challenging due to their slow decomposition rate. However, small bones can be broken down more effectively if crushed and mixed with other compostable materials.
What materials should not be composted?
Avoid composting materials like diseased plants, glossy paper, synthetic chemicals, and pet waste. These can introduce pathogens or toxic substances into your compost.
How long does it take to compost in a tumbler?
Composting in a tumbler typically takes 2-3 months, depending on the materials used and environmental conditions. Regular turning and maintaining the right moisture and temperature levels can accelerate the process.
Conclusion
While composting meat and dairy in a compost tumbler is challenging, it is possible with careful management and attention to detail. For those seeking safer and easier options, consider alternatives like bokashi composting or municipal services. By understanding the risks and benefits, you can make informed decisions about your composting practices.
