Study Notes

Waste and Its Impact

  • Waste consists of discarded materials from homes, factories, offices, schools, markets, hospitals, and hotels.
  • Waste negatively impacts the environment through land, water, and air pollution.
  • Improper waste disposal leads to unclean surroundings and blocked drains, causing foul odors.
  • Garbage serves as breeding grounds for disease-spreading pests like flies, mosquitoes, and rats.
  • These pests spread diseases.
  • Proper waste disposal is crucial for maintaining a healthy environment.
  • Waste leads to dirty and unsightly areas.

Two Categories of Waste

  • Waste is divided into biodegradable and non-biodegradable types.

Biodegradable Waste

  • Biodegradable waste rots easily and mixes with the soil.
  • Examples include leftover food, fruit and vegetable peels, paper, fallen leaves, and animal waste. Additionally, human waste is biodegradable.
  • Microorganisms like bacteria and fungi decompose biodegradable waste.
  • Human waste is biodegradable.

Non-biodegradable Waste

  • Non-biodegradable waste does not rot easily and remains in the environment for long periods, causing pollution.
  • Examples include plastic goods, polythene bags, silver foil, aluminum cans, glass, metals, and electronic parts.
  • Non-biodegradable waste pollutes the soil.
  • Non-biodegradable waste persists in the environment for extended durations and causes environmental pollution.

Waste Disposal

  • Home waste goes into dustbins and is collected by garbage collectors.
  • Local municipal authorities transport the waste and use different disposal methods.
  • Garbage collectors gather waste and put it into large garbage bins in the locality.
  • Trucks from local municipal authorities collect garbage.

Open Dumping

  • Open dumping involves disposing of waste in open areas away from urban centers.
  • This method pollutes the environment.
  • Waste is transported away from the town or city and dumped in the open.
  • Disposing of waste in the open pollutes the environment.

Landfills

  • Landfills involve burying waste in deep ditches, then covering them with soil when full.
  • Parks or gardens are sometimes built on top of completed landfills.
  • Landfills are usually on the outskirts of cities.

Incineration

  • Incineration is the burning of waste to ashes.
  • It involves burning waste at high temperatures in a furnace called an incinerator.
  • The heat generated can be used to produce electricity.

Composting

  • Composting involves placing biodegradable waste in compost pits or bins for decomposition into compost.
  • Compost is used as a natural fertilizer by farmers.
  • Composting is an environmentally friendly and cost-effective method for disposing of biodegradable waste.
  • Composting is among the cheapest and easiest ways to dispose of biodegradable waste.
  • Compostable waste is collected from kitchens and gardens.

The 3 R's

  • Reduce, Reuse, and Recycle comprise an effective approach to waste management and environmental conservation.
  • The most effective way to dispose of waste and conserve the environment is to follow the three R's.
  • It advocates for producing less waste and finding ways to reuse and recycle items.

Reduce

  • Lowering waste production helps minimize pollution.
  • Individuals should aim to buy only what they need and avoid wasting food.
  • Producing less waste helps reduce pollution.
  • Reducing waste involves changing consumption habits.

Reuse

  • Reusing items for different purposes extends their usability.
  • Examples include using cardboard boxes or shoeboxes for storage, plastic jars or aluminum cans as pencil holders, and old clothes transformed into shopping bags or dusters.

Recycle

  • Recycling converts waste materials into new products, conserving resources and energy.
  • Recycling reduces pollution.
  • Paper is a recyclable material; plastic and metal can also be recycled.
  • Sorting waste before disposal is recommended to facilitate recycling efforts.
  • Recycling saves materials and energy required to produce them.
  • Segregating waste before disposing of it is important.
  • Plastic and metal can be recycled.
