Question : Statement 1: Waste segregation at source is an effective waste management practice that involves separating different types of waste for proper disposal or recycling.
Statement 2: Waste segregation helps reduce the burden on landfill sites, promotes recycling, and minimizes environmental pollution.
Option 1: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Option 2: Both statement 1 and statement 2 are true, but statement 2 is not the correct explanation of statement 1 .
Option 3: Statement 1 is true, but statement 2 is false.
Option 4: Statement 1 is false, but statement 2 is true.
Correct Answer: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Solution : The correct option is (A) Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1.
Statement 1 is true: Waste segregation at source is indeed an effective waste management practice. It involves separating different types of waste at the point of generation, such as homes, businesses, or institutions. The purpose of waste segregation is to sort waste into specific categories, such as recyclables (e.g., paper, plastics, glass, metal), organic waste, and hazardous waste. This segregation allows for proper disposal, recycling, or treatment of different waste streams, maximizing resource recovery and minimizing environmental impacts.
Statement 2 is the correct explanation of statement 1 . Waste segregation does help reduce the burden on landfill sites, promote recycling, and minimize environmental pollution. When waste is segregated at source, recyclable materials can be diverted from landfill and sent for recycling or reuse, reducing the amount of waste that ends up in landfills. This helps prolong the lifespan of landfill sites and reduces the environmental and health risks associated with landfills, such as groundwater contamination and methane emissions. Additionally, by separating organic waste, it can be composted or used for anaerobic digestion, which contributes to nutrient cycling and reduces greenhouse gas emissions. Proper segregation of hazardous waste also ensures its safe disposal or treatment, minimizing potential harm to human health and the environment.
Both statements are true, and statement 2 provides the correct explanation for statement 1.
Question : Statement 1: E-waste recycling is an essential aspect of sustainable waste management.
Statement 2: Improper disposal of electronic waste can lead to environmental pollution and the release of hazardous substances into the ecosystem.
