What is Solid Waste Management (SWM)?

Back

SWM is a system associated with the control of generation, storage, collection, transfer, transport, processing, and disposal of solid wastes in a manner that adheres to public health, economic, engineering, conservation, aesthetic, and environmental considerations.

Front

What are the two fundamental objectives of solid waste management?

Back

1. To minimize waste. 2. To manage the waste still produced.

Front

What are the main components of the 3R approach in solid waste management?

Back

1. Reduce - Minimizing the amount of waste generated. 2. Reuse - Finding ways to use materials again. 3. Recycle - Processing waste materials for reuse.

Front

What historical methods were commonly used for solid waste disposal at the turn of the century?

Back

1. Dumping on land 2. Dumping in water 3. Plowing into the soil 4. Feeding to hogs 5. Reduction 6. Incineration.

Front

What is the significance of the industrial revolution in waste generation?

Back

The industrial revolution marked the beginning of a technological society, leading to increased waste generation alongside the benefits of technology.

Front

What are the effects of modern technological advances on solid waste management?

Back

Modern technological advances create a constantly changing set of parameters for waste management, increasing the complexity of designing solid waste facilities.

Front

What is the role of resource recovery in solid waste management?

Back

Resource recovery involves reclaiming materials from waste for reuse, recycling, or energy recovery, thus minimizing the amount of waste that needs to be disposed of.

Front

What are the key activities associated with waste generation?

Back

Waste generation is an activity that is not easily controllable, but future efforts will focus on exercising more control over the generation of wastes.

Front

What is the importance of on-site storage in waste management?

Back

On-site storage is crucial for public health and aesthetic considerations, as it helps manage waste before collection.

Front

What are the steps involved in the transfer and transport of solid wastes?

Back

1. Transfer waste from smaller collection vehicles to larger transport equipment. 2. Transport the wastes to processing or disposal sites.
