FAQs on Waste Management Video Lecture - Chemistry Class 11 - NEET

1. What is waste management?
Ans. Waste management refers to the process of collecting, treating, and disposing of waste materials in an environmentally friendly and sustainable manner. It involves various activities such as recycling, landfilling, incineration, and composting to minimize the negative impact of waste on the environment.
2. Why is waste management important?
Ans. Waste management is crucial for several reasons. Firstly, it helps to protect the environment by reducing pollution and preventing the release of harmful substances into the air, water, and soil. Secondly, proper waste management promotes public health and safety by preventing the spread of diseases and reducing the risk of accidents. Additionally, it conserves natural resources, reduces greenhouse gas emissions, and contributes to a more sustainable future.
3. What are the different methods of waste management?
Ans. There are several methods of waste management, including: 1. Landfilling: Waste is disposed of in designated landfills where it is compacted and covered with soil to prevent contamination. 2. Recycling: Materials such as paper, plastic, glass, and metal are sorted, processed, and transformed into new products. 3. Incineration: Waste is burned at high temperatures, producing energy and reducing the volume of waste. However, this method should be accompanied by proper air pollution control measures. 4. Composting: Organic waste, such as food scraps and yard trimmings, is decomposed naturally and transformed into nutrient-rich compost for soil enrichment. 5. Waste-to-energy: Certain types of waste, such as non-recyclable plastics, can be converted into energy through processes like gasification or pyrolysis.
4. How can individuals contribute to waste management?
Ans. Individuals can play a significant role in waste management through the following actions: 1. Reduce waste generation by practicing mindful consumption and avoiding unnecessary packaging. 2. Reuse items whenever possible instead of buying new ones. 3. Recycle materials that are accepted by local recycling programs. 4. Separate organic waste for composting, either through home composting or community composting initiatives. 5. Properly dispose of hazardous waste, such as batteries and electronic devices, by utilizing designated collection points or programs.
5. What are the challenges faced in waste management?
Ans. Waste management faces various challenges, including: 1. Lack of public awareness and participation: Many people are not sufficiently informed about the importance of proper waste management and the actions they can take to contribute. 2. Insufficient infrastructure and resources: Adequate facilities, such as recycling centers and composting facilities, may be lacking in certain areas, making it difficult to manage waste effectively. 3. Illegal dumping and littering: Improper disposal practices, such as illegal dumping and littering, contribute to environmental pollution and pose health risks. 4. Increasing waste generation: As populations and consumption patterns continue to grow, the amount of waste generated also rises, putting additional strain on waste management systems. 5. Technological advancements: The rapid pace of technological advancements introduces new types of waste, such as electronic waste, which require specialized handling and disposal methods.
