Match List I with List II:

The correct matches are recycling generating employment, incineration generating fly-ash, pyrolysis heating waste in an oxygen depleted environment, and salvage separating reusable articles manually.

Recycling pairs with generating employment opportunities as collection and processing need labour.

Incineration pairs with generating fly-ash, the fine residue left after burning solid waste.

Pyrolysis pairs with heating solid wastes in an oxygen depleted environment to break them down.

Salvage pairs with manually separating reusable articles from the waste stream.

These methods represent different strategies of solid waste handling, from recovery to thermal treatment.
