Bangalore method is a method of?

Appeared in: KPSC Staff Nurse - 2015

Explanation

The Bangalore method is a scientifically developed technique for the disposal of solid municipal waste.
It specifically uses anaerobic composting (decomposition without oxygen) to break down a mixture of town refuse and night soil (human excreta).
The process takes place in trenches and results in the production of manure over 4-6 months, making it a method of waste disposal and resource recovery.
It is classified under composting, which is a principal method of refuse disposal.

Option A: While the Bangalore method uses night soil (excreta), its main purpose is to process large volumes of solid municipal refuse. It is a combined disposal system, not solely for excreta.
Option C: Water purification involves processes that remove contaminants from water to make it safe for consumption. This is entirely different from solid waste management.
Option D: Vector control is a secondary benefit of the Bangalore method. The high temperatures generated during composting kill fly larvae and other pests. However, the primary purpose of the method is waste disposal, not vector control itself.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Methods of Waste Management as background academic context rather than a clinical decision trigger.
Understanding waste management methods is crucial for community health nurses to prevent the spread of infectious diseases.
Improper disposal of waste and excreta can lead to contamination of soil and water, causing outbreaks of diseases like cholera, typhoid, dysentery, and parasitic infections.
Nurses play a key role in educating communities about sanitary practices, including proper waste disposal, to reduce environmental health hazards.

How to Approach the Question

First, identify the key term in the question: 'Bangalore method'.
Recall topics related to environmental health and sanitation from your community health nursing studies.
Recognize that this is a specific, named technique for managing waste.
Evaluate the options. 'Waste disposal' is a broad category. 'Excreta disposal' is a sub-part of waste management. 'Water purification' is a different environmental health topic. 'Vector control' is often related to waste but is a consequence, not the primary method.
Confirm that the Bangalore method is a type of composting, which falls directly under 'Waste disposal'. Eliminate the other options as either too narrow, incorrect, or a secondary benefit.
