Assessment
Answer the following questions
1. Why is it necessary to segregate our garbage at source?
Ans: Segregating garbage at source is crucial for several reasons:
Efficient Waste Management: Segregation simplifies the waste management process, allowing for more efficient collection, transportation, and treatment of different waste streams. This reduces the burden on landfills and incineration facilities.
Resource Recovery and Recycling: Segregated waste facilitates resource recovery and recycling. Valuable materials like paper, plastic, metal, and glass can be extracted from segregated waste streams and processed into new products, reducing the need for virgin resources and conserving natural resources.
Environmental Protection: Proper segregation of waste prevents hazardous materials from contaminating non-hazardous waste, minimizing the risk of environmental pollution. It also reduces the release of harmful greenhouse gases from landfills and incinerators.
Economic Benefits: Segregation promotes a circular economy, creating opportunities for job creation and economic growth in the waste management and recycling sectors. It also reduces the costs associated with waste disposal and environmental cleanup.
Public Health and Safety: Segregating waste at source promotes public health and safety by preventing the spread of diseases caused by improper waste disposal. It also reduces the risk of accidents and injuries associated with unsegregated waste handling.
Sustainable Future: Segregating waste is an essential step towards achieving a sustainable future. It reduces our reliance on finite resources, minimizes environmental pollution, and promotes a more responsible approach to waste management.
