What is Waste Disposal?
Waste disposal is the systematic act of collection, processing, and disposal of waste produced from industrial, agricultural, and domestic sources.
How can Waste Disposal be Improved?
There are four ways to improve waste disposal:
- Composting: Composting is the controlled decomposition of degradable organic wastes into stable products with the help of microorganisms.
- Recycling: It is the reprocessing of waste materials into usable products, reducing the consumption of fresh raw materials, energy usage, air pollution (from incineration), and water pollution by reducing the need for “conventional” waste disposal.
- Reduce packaging: Excessive packaging can instantly multiply the amount of waste. Choosing low-packaging alternatives can help eliminate disposable products like bottled water altogether.
- Going paperless: Papers account for almost 35% of the waste that is dumped in landfills. Paper waste can be reduced by replacing paper towels with old clothes for cleaning around the house.
Why is Improper Waste Disposal a Problem?
Improper disposal of waste has grave environmental impacts and can cause serious health problems.
- While some waste will eventually rot, some will not, and in the process, it becomes malodorous, produces methane, which contributes to the greenhouse effect.
- The production of leachate during the decomposition of wastes may cause land and water pollution. Ill-managed landfill sites become a breeding ground for vermins or cause litter.
- Incinerating plastic wastes could lead to the production of toxic substances like dioxin. Moreover, the gases from incineration may cause air pollution and contribute to acid rain, while the ash in the incinerators may contain other dangerous toxins and heavy metals.
Are Waste Disposal Units Environmentally Friendly?
Waste disposal units are much more environmentally sound than simply throwing the garbage into a landfill. Putrefying wastes give off methane gas, which pollutes the air and contributes to the rising problem of greenhouse gases.
