DIFFERENT-TYPES-OF-WASTES

Types of Waste

  • Basic Categories of Waste: Includes solid waste, liquid waste, gaseous waste, biodegradable waste, and non-biodegradable waste.

Waste Management Methods

  • Main Strategies:

    • Composting: Converting organic waste into useful compost.

    • Landfill: Burial of waste in designated areas.

    • Recycling: Processing materials to create new products.

    • Reducing: Minimizing waste creation through careful consumption.

    • Reusing: Extending the lifespan of products through repeated use.

    • Incineration: Burning waste to reduce volume and generate energy.

Understanding Waste

  • Definition of Waste: Unusable or unwanted materials discarded after primary use; materials that are worthless or defective.

Waste Generation in the Philippines

  • Accelerated Waste Production Factors: Increasing industrialization, urbanization, and population growth are leading to higher waste generation, particularly in urban areas.

Types of Waste by Form

  • 1. Solid Waste:

    • Comes in various forms including domestic (household), commercial, and industrial waste (e.g., plastics, papers).

  • 2. Liquid Waste:

    • Includes chemicals, oils, and wastewater; covers sewage and industrial wastewater.

  • 3. Gaseous Waste:

    • Discharges from industrial processes, including carbon dioxide and methane.

Biodegradable vs. Non-biodegradable Waste

  • A. Biodegradable Waste:

    • Kitchen scraps and garden waste; also termed moist waste.

  • B. Non-biodegradable Waste:

    • Involves materials like plastics and broken glass that do not decompose easily; considered major pollutants.

Detailed Types of Waste

  • Municipal Solid Waste:

    • Includes household garbage, construction debris, and sanitation residues managed by municipalities.

  • Industrial Waste:

    • Generated by manufacturing processes, comprising both solid and liquid waste from various industries.

  • Agricultural Waste:

    • Wastes from farming activities, predominantly biodegradable. Includes fishery wastes from coastal activities.

  • Radioactive Waste:

    • By-products of nuclear processes or industries producing radioactive isotopes.

E-Waste

  • Definition: Electronic wastes derived from discontinued electrical and electronic devices, often containing hazardous substances.

5 R's of Waste Management

  • 1. Reduce:

    • Minimize consumption and waste production; practical tips include avoiding single-use plastics, shopping in bulk, and mindful purchasing.

  • 2. Reuse:

    • Finding new uses for items to extend their utility and reduce waste; applicable to various materials like furniture and glass.

  • 3. Recycle:

    • Process of reusing materials; crucial for conserving resources and limiting landfill waste.

  • 4. Repurpose:

    • Giving items new roles beyond their original use; helps reduce landfill contributions.

  • 5. Refuse:

    • Act of declining unnecessary items; promotes a more sustainable lifestyle and less waste production.

Health Impacts of Waste

  • Effects on Human Health:

    • Risks include chemical poisoning, increased cases of cancer, congenital malformations, and neurological diseases due to exposure to uncollected waste.

Environmental Effects of Waste

  • Effects on Ecosystems:

    • Waste leads to soil, air, and water contamination; contributes to climate change and disrupts local wildlife.

Waste Treatment Methods

/

  • Major Methods:

    • Thermal Treatment: Incineration, gasification, pyrolysis, and open burning.

    • Dumps and Landfills: Traditional waste storage practices.

    • Biological Treatment: Methods to decompose organic waste effectively.

Incineration Process

  • In a waste-to-energy facility:

    • Solid waste is burned to generate steam, which turns turbines to produce electricity. Emissions are filtered through pollution control technologies to mitigate harmful airborne particles
