A household chooses to repair old electronic items instead of discarding them and buying new ones. This practice is an example of which of the 3Rs?
Reduce
Reuse
Recycle
Refuse
Reuse
The 3Rs principle is a waste management hierarchy aimed at environmental sustainability. Repairing an item to extend its functional lifespan before discarding it is classified as 'Reuse', as it prevents the item from entering the waste stream.

If you patch a hole in your jeans rather than throwing them away to buy new ones, you are reusing the fabric instead of demanding new production.
R3: Reduce (use less), Reuse (use again), Recycle (process into raw material).
╬ФE=EnewтАЛтИТErepairтАЛ тАФ the energy saved by opting to repair rather than manufacture new items.
Reuse operates on the principle of resource conservation by maintaining the object's original form and function. By delaying the transition of an object into waste, the demand for raw materials required to manufacture a new replacement is mitigated, significantly lowering the total energy expenditure (EtotalтАЛ) associated with the product lifecycle.
Reuse prevents the immediate generation of electronic waste (e-waste).
It maintains the embedded energy already invested in the product's original manufacture.
Repairing is chemically and physically preferable to recycling, which often involves complex chemical decomposition or high-temperature melting.
Reduces the requirement for extracting virgin raw materials.
Lowers the carbon footprint of the consumer.
Decreases the volume of hazardous materials released into the environment.
May be cost-prohibitive if repair parts are unavailable.
Technological obsolescence can limit the utility of repaired electronics.
Repairing a broken smartphone screen.
Refurbishing old desktop computers for reuse in schools.
The 3Rs hierarchy is prioritized: Reduce > Reuse > Recycle.
Option A (Reduce) involves consuming fewer resources initially; Option C (Recycle) involves breaking the item down into base materials; Option D (Refuse) involves declining to use non-sustainable products altogether.
B is correct тАФ Repairing an item extends its lifecycle, keeping it in active use rather than turning it into waste.
In competitive exams, remember that 'Recycle' requires an industrial process of conversion into raw materials, whereas 'Reuse' keeps the item in its current functional form.
