⚠️ Potential Risks

Risks
  • Attracting pests: Smaller pieces might attract pests like rodents or insects if not properly managed within the compost pile.
  • Slow decomposition: Shrimp shells decompose more slowly than many other organic materials, so be patient.
  • Potential for odor: If not properly buried or managed in a well-aerated compost pile, shrimp shells can contribute to unpleasant odors.

💡 Best Practices

Best Practices
  • Crush shells before adding them to the compost to speed up decomposition.
  • Mix them well with other "brown" and "green" materials in your compost heap for a balanced mix.
  • Ensure your compost pile is well-aerated to prevent foul odors. Turn your pile regularly.
  • Add shells in small quantities to avoid overwhelming the compost with calcium.
