Composting Safety Tips: What Not to Compost and Avoiding Hazards

Composting is an excellent way to reduce your environmental impact, recycle organic waste, and create nutrient-rich soil for your garden. However, there are certain materials that should not be composted due to potential health risks and environmental hazards.

What Not to Compost:

Meat, Fish, and Dairy Products
  • Meat, Fish, and Dairy Products: These items can attract pests and rodents, contaminate the compost with harmful bacteria, and release unpleasant odors.
  • Bones: Bones take a long time to decompose and can harbor harmful bacteria.
  • Fats, Oils, and Grease: These materials can slow down the composting process and attract pests.
  • Diseased Plants: Plants infected with diseases can spread the infection to other plants in your compost pile.
  • Weeds with Seeds: Composting weeds with seeds can lead to their spread throughout your garden.
  • Treated Wood or Lumber: Treated wood contains chemicals that can contaminate the compost and harm plants.
  • Pet Waste: Pet waste can contain harmful bacteria and parasites that can spread to humans and other animals.
  • Chemicals and Pesticides: Chemicals and pesticides can contaminate the compost and harm plants and soil.

Avoiding Hazards:

Wear Gloves When Handling Compost
  1. Properly Maintain Your Compost Pile: Regularly turn and aerate your compost pile to prevent anaerobic conditions that can lead to the production of harmful gases and odors.
  2. Wear Gloves When Handling Compost: Composting materials can contain harmful bacteria and pathogens. Always wear gloves to protect your hands when handling compost.
  3. Store Compost Properly: Keep your compost pile in a secure location away from children and pets. Cover the pile to prevent pests and rodents from accessing it.
  4. Use Compost Responsibly: Apply compost to your garden or lawn sparingly to avoid nutrient overload and potential plant damage.
  5. Be Aware of Local Regulations: Some areas have specific regulations regarding composting. Check with your local authorities to ensure you comply with these regulations.
