Key Points

  • Waste can be classified into two main categories: biodegradable and non-biodegradable.
  • Biodegradable waste includes organic materials like food scraps, paper, and plant debris that decompose naturally.
  • Non-biodegradable waste includes plastics, metals, and glass that do not decompose easily and may harm the environment.
  • It is essential to separate dry waste (like plastics, metals, glass) and wet waste (organic waste) for proper disposal and recycling.
  • Segregation of waste aids in the efficient recycling process and minimizes environmental hazards.
  • Biodegradable waste can be turned into compost, which is beneficial for agriculture, while non-biodegradable waste can be recycled to reduce pollution.
  • Proper waste segregation practices align with global efforts to promote sustainable waste management.
