After processing electronic waste, remaining plastics are used for which purpose?

• A. Used as aggregates for making pavements.
• B. Melted into reusable beverage containers.
• C. Converted into fuel for power generation.
• D. Burned for energy without recovery.

Answer: (A)

The main idea here is turning waste into construction material through material recycling. After processing electronic waste, plastics can be ground and repurposed as aggregates in road construction. This upcycling helps reduce the need for virgin aggregates, lowers landfill use, and fits with sustainable waste management.

Using plastics as aggregates in pavements can be done by incorporating them into asphalt mixes or asphalt concrete, sometimes as a partial substitute for natural aggregates or as a modifier to improve certain performance characteristics when done properly.

Other paths—melting plastics into new beverage containers, converting plastics into fuel for power generation, or burning them for energy without recovery—are less practical in this context. Beverage-grade recycling needs clean, specific food-contact plastics not typically present in e-waste; converting to fuel is an energy-recovery route that doesn’t reuse the material in a form suitable for road construction; burning without recovery wastes potential energy and materials.
