Which of the following sequences of disposal options for low hazardous solid waste from industrial and urban sources is in order of increasing desirability?
Indiscriminate dumping < Landfill < Incineration < Reuse
When disposing of low hazardous solid waste from industrial and urban sources, it is crucial to choose methods that are both environmentally and socially sustainable. Here's a step-by-step explanation of the correct order of increasing desirability for disposal options:
- Indiscriminate Dumping: This is the least desirable option. It involves carelessly dumping waste without considering environmental or health implications. It can lead to pollution and health hazards. As such, it is not a recommended practice.
- Landfill: This option involves disposing of waste in designated areas. While better than indiscriminate dumping, landfills still pose risks such as soil and groundwater contamination. Properly managed landfills can mitigate some of these issues but are still not the most preferred option.
- Incineration: This method involves burning waste to reduce its volume. Incineration is more desirable than landfills as it can significantly reduce the waste volume and, in some cases, recover energy. However, it can release harmful emissions if not managed properly.
- Reuse: The most desirable option, reuse involves finding new ways to use materials that would otherwise become waste. This method conserves resources and reduces the need for waste treatment and disposal.
The sequence from least to most desirable practices based on this explanation is: Indiscriminate dumping < Landfill < Incineration < Reuse.
