Source Reduction Examples at Home and in Industry: AP Environmental Science

📚 Quick Study Guide

• 🌱 Definition: Source reduction, also known as waste prevention, aims to minimize waste generation at its source. It's the most preferred waste management strategy.
• 🏠 At Home:
  • 🛍️ Choose reusable shopping bags.
  • 💧 Buy products in bulk to reduce packaging.
  • 🛠️ Repair items instead of replacing them.
  • 📝 Reduce junk mail by opting out of mailing lists.
• 🏭 In Industry:
  • ♻️ Implement closed-loop systems where waste from one process becomes input for another.
  • 📦 Redesign products to use less material.
  • 🧪 Optimize manufacturing processes to minimize scrap.
  • 💸 Implement inventory management to reduce surplus.
• ⚖️ Benefits:
  • 📉 Reduces the amount of waste needing disposal.
  • ⬇️ Conserves natural resources.
  • 🌍 Minimizes pollution from manufacturing and disposal.
  • 💰 Saves money for both consumers and industries.
• 🔢 Key Formula: Waste Reduction Efficiency = $\frac{\text{Original Waste} - \text{New Waste}}{\text{Original Waste}} \times 100$%
