    Study Notes

    Waste Sorting and Disposal

    • Different coloured containers are used for specific types of waste:
      • Blue: Paper-based waste (boxes)
      • Yellow: Metallic waste (iron)
      • Orange: Plastic waste (bottles)
      • Grey: Glass-based waste (broken glass cups)
      • Red: Electronic waste (broken cell phones, chargers, batteries)
      • Green: Organic waste (food remains)

    Importance of Proper Waste Disposal

    • Prevention of Disease Spread: Accumulated waste attracts insects (houseflies, mosquitoes) and rodents (rats) that spread diseases like dysentery, cholera, and malaria.
    • Prevention of Unpleasant Smell: Decomposing waste produces a foul odor that can be disturbing.
    • Keeping the Environment Clean: Scattered waste makes the environment unsightly, while proper disposal keeps it clean and attractive.
    • Prevention of Accidents: Accumulated waste can hide dangerous organisms (snakes, scorpions, centipedes) and sharp objects (broken glass, metal pieces) that can cause injury.
    • Prevention of Water Pollution: Waste can contaminate water sources with toxins and pathogens, affecting human and animal health.

    Waste Sorting

    • Waste sorting helps with proper disposal and recycling by categorizing waste based on its properties.
    • Waste types include:
      • Combustible Wastes: Dry waste (paper, wood, leaves, clothes)
      • Non-combustible Wastes: Ceramics, utensils, glass, metals
      • Hazardous Wastes: Harmful to the environment and living things, require special disposal (expired medicines, batteries, radioactive waste, scrap metals)
      • Non-hazardous Wastes: Harmless to the environment and living things (paper, wooden materials)

    Waste Disposal Methods

    • Incineration:
      • Uses high temperatures to burn waste and reduce volume.
      • Incinerators typically have the following components:
        • Combustion Chamber: Where waste is burned
        • Chimney: Releases smoke upwards to minimize air pollution

    Incinerator Location Considerations

    • Distance from Settlements: Built far from human settlements to avoid smoke and odor.
    • Wind Direction: Constructed considering wind direction to prevent smoke from blowing towards settlements.
    • Combustible Materials: Located away from flammable materials to avoid accidents.
    • Electrical Lines: Distance from electrical lines to prevent accidents.
    • Water Sources: Should be far from water sources to prevent pollution.

    Waste Disposal

    • Different coloured containers are used to dispose of different types of waste.
    • Blue containers – Paper waste (boxes)
    • Yellow containers - Metallic waste (iron)
    • Orange containers – Plastic waste (plastic bottles)
    • Grey containers – Glass waste (broken glass cups)
    • Red containers – Electronic waste (broken cell phones, chargers, batteries)
    • Green containers – Organic waste (food remains)

    Choosing Waste Disposal Areas

    • Waste disposal should be done in a safe way that does not harm people or the environment.
    • Waste should be disposed of in areas that will not contaminate water sources.
    • Waste disposed of in an area can occupy a lot of land.
    • Waste can be destroyed by methods such as compaction or ash formation, which frees up land for other purposes.

    Benefits of Incinerators

    • Heat from incinerators can generate electricity, which is useful for operating machines and equipment.
    • The heat can also be used to boil water, producing steam that can then be used to run electric generators.
    • Heat from incinerators can warm houses, which is especially useful in cold climates.
    • Incineration can also be used to produce fertilizer from burned waste, which is useful for increasing crop yields.
    • Proper waste disposal can reduce the harmful effects of toxic wastes on soil organisms.

    Waste Disposal Methods

    • Crushing and landfilling is a method for disposing of solid waste that cannot be easily burned.
    • Solid waste that can be burned is disposed of using fire.
    • Incinerators are used to burn solid waste. Incinerators have three main parts: air inlet and ash vent, combustion chamber, and chimney.
    • The air inlet and ash vent allows air into the incinerator, which helps to burn the waste. It is also used to remove ashes after the waste is burnt.
    • The combustion chamber is where the waste is placed and burned.
    • The chimney releases the combustion gases into the air.

    Criteria for Incinerator Construction

    • Incinerators should be located far from human settlements to prevent harm and pollution.
    • Incinerators should be located in areas that have plenty of waste to burn.
    • Incinerators should be located far from combustible materials to prevent fires.

    Advantages of Burning Waste

    • Burning waste can help to prevent the spread of disease-causing organisms and insects.
    • Burning waste is also relatively inexpensive.

    Disadvantages of Burning Waste

    • Burning waste reduces soil fertility.
    • Burning waste can also cause air pollution.

    Waste Collection & Disposal

    • Different coloured containers are used for different types of waste, including paper, metal, plastic, glass, electronic waste, and organic waste.
    • An incinerator is a device used to burn waste materials.
    • The main parts of an incinerator are:
      • Air inlet and ash vent: Allows air into the incinerator for burning and is used to remove ashes.
      • Combustion chamber: This is where wastes are placed and burned.
      • Chimney: Emits smoke and gases high into the atmosphere.
    • When choosing a location for an incinerator, consider the following:
      • It should be away from human settlements, but easily accessible.
      • It should be built considering wind direction to prevent smoke from blowing toward settlements.
      • Avoid constructing near combustible materials.
      • Avoid constructing near electrical lines.
      • Avoid constructing near water sources to prevent pollution.

    Advantages of Waste Disposal

    • Proper waste disposal can prevent the spread of diseases by eliminating breeding grounds for insects like houseflies and mosquitoes.
    • Proper waste disposal can prevent unpleasant smells caused by decomposing waste.
    • Proper disposal keeps the environment clean and attractive.
    • Proper waste disposal can avoid accidents caused by hazardous waste materials or animals attracted to waste.
    • Waste disposal helps prevent water pollution by ensuring waste does not contaminate water sources.

    Incinerator Construction

    • Simple incinerators can be constructed using iron ore, cement, coarse aggregates and sand.
    • Materials used for incinerator construction depend on the intended use.
    • Industrial incinerators are made with steel that cannot easily melt.
    • Incinerators are not a perfect solution for all waste, as they can contribute to air pollution.
