What are three primary methods for the disposal of plastics?

The answer highlights three primary methods for disposing of plastics: landfilling, recycling, and incineration.

Landfilling is one of the most common methods of plastic disposal where waste is buried in designated areas. This method, while straightforward, raises environmental concerns such as soil and groundwater contamination.

Recycling is critical as it allows for the recovery of useful materials from used plastics, promoting sustainability and reducing the demand for new raw materials. Through recycling, plastics are processed and converted into new products, which not only helps to manage waste but also decreases the environmental impact associated with raw material extraction and processing.

Incineration involves burning plastics at high temperatures, which can reduce the volume of waste significantly. However, it is essential to manage this process carefully to minimize harmful emissions and environmental pollution. In energy recovery incineration, the heat generated can be harnessed for electricity or heating.

The other options do not accurately represent primary methods for plastic disposal. Burning and burying are somewhat aligned with incineration and landfilling but lack the specificity and comprehensive coverage that the correct choice provides. Shredding, melting, and remolding describe processes related to recycling rather than methods of disposal. Storing, recycling, and donating mix disposal with alternative waste
