MCQ on Solid Waste Management

Advertisements

Solid waste management refers to the process of collecting, treating, and disposing of solid waste in a safe, effective, and environmentally sound manner. Solid waste includes all non-liquid waste generated by human activities, such as household waste, industrial waste, and construction debris.

The goal of solid waste management is to reduce the negative impacts of waste on the environment and public health, while maximizing the value that can be obtained from waste. The main methods of solid waste management are:

  1. Source reduction: This involves reducing the amount of waste generated by producing fewer waste products, using more durable products, and avoiding over-packaging.
  2. Recycling: This involves collecting and reprocessing waste materials into new products. Recycling can reduce the need for raw materials, save energy, and reduce pollution.
  3. Composting: This involves breaking down organic waste into compost, which can be used as a soil amendment. Composting can reduce the amount of waste that goes to landfills and can also reduce greenhouse gas emissions.
  4. Incineration: This involves burning waste to generate energy or reduce the volume of waste. Incineration can be used for non-recyclable and non-compostable waste, but can also release pollutants into the air.
  5. Landfilling: This involves burying waste in an engineered facility designed to prevent environmental contamination. Landfills can be used for non-recyclable and non-compostable waste, but can also take up a lot of space and can release methane gas into the atmosphere.

Hazardous waste, such as chemicals and medical waste, requires special handling and disposal to prevent harm to public health and the environment. Hazardous waste is often treated through methods such as chemical treatment, thermal treatment, or secure landfills.
