Integrated Solid Waste Management-II

The correct hierarchy for the Principles of Waste Generation is Reduce-Reuse-Recycle-Recover-Res. Management. This hierarchy emphasizes the importance of first reducing waste generation by minimizing consumption and using resources efficiently. Next, it promotes the reuse of materials and products to extend their lifespan and reduce the need for new production. Recycling comes next, which involves converting waste materials into new products. Recovering refers to the extraction of energy or valuable resources from waste through processes like incineration or anaerobic digestion. Lastly, Res. Management involves proper management and disposal of waste that cannot be reduced, reused, recycled, or recovered.

IC&I stands for Industrial, Commercial, and Institutional. These are the sources of Municipal Solid Waste (MSW). Industrial waste refers to waste generated by manufacturing and production processes. Commercial waste includes waste generated by businesses and offices. Institutional waste refers to waste generated by schools, hospitals, government buildings, and other institutions. Therefore, IC&I is the correct answer as it encompasses the various sources of MSW.

The statement "DLC Wastes managed at private sites" is true. This means that DLC (Dangerous and Hazardous Waste) is handled and disposed of at private sites rather than public or government-owned sites. Private sites may include specialized facilities or companies that are licensed and equipped to handle and manage hazardous waste in a safe and environmentally responsible manner.

DLS Wates are not putrescible.

Changes in society's standards of living, conveniences, and economic wealth directly impact the composition of waste in landfills. As societies become more affluent and technologically advanced, their consumption patterns change, leading to the generation of different types of waste. For example, increased use of electronic devices and single-use plastics contribute to the growing amount of electronic waste and non-biodegradable materials in landfills. Additionally, changes in lifestyle and consumer behavior, such as the shift towards fast fashion or the adoption of disposable products, further influence the composition of waste. Therefore, it is true that changes in society's standards of living, conveniences, and economic wealth are major factors causing changes in the composition of waste in landfills.

Packaging can sometimes reduce overall waste by providing protection and extending the shelf life of products, thus reducing the likelihood of spoilage and the need for replacement. Additionally, packaging can facilitate efficient transportation and distribution, reducing the energy and resources required for shipping. Properly designed packaging can also enable recycling and promote the use of sustainable materials, further minimizing waste. However, it is important to note that excessive or unnecessary packaging can contribute to waste generation, so the overall impact of packaging on waste reduction depends on its design and usage.

The correct answer is "Recycle" because putting food scraps into a backyard compost bin is a form of recycling. Composting is the process of breaking down organic materials like food scraps into nutrient-rich soil that can be used to fertilize plants. By composting, Lyle is diverting waste from the landfill and creating a valuable resource for his garden.

The given correct answer is "Recycle" because MEC sells fleece jackets made from 2L pop bottles. This indicates that MEC is taking used pop bottles and processing them in a way that allows them to be used again in the production of jackets. Recycling is the process of converting waste materials into reusable materials, and in this case, MEC is recycling the pop bottles to create new products, promoting sustainability and reducing waste.

The correct answer is "Reuse" because Rolf is wearing his brother's hand-me-down clothes, which implies that he is reusing them instead of throwing them away or buying new clothes. Reusing clothes is a great way to reduce waste and minimize the environmental impact of the fashion industry.
