Final answer:
Plastics recycling faces challenges, and the lack of market for recyclables can result in landfill or incineration. Metal recycling is more efficient than plastic recycling, and reducing plastic use is recommended.
Step-by-step explanation:
Plastics recycling faces challenges due to its massive production and non-biodegradable nature. With no market for many recyclables, these items may end up in landfills or incinerators. Recycling is a preferred approach to reduce environmental contamination, but it still requires a lot of energy to process recycled goods. Metal recycling, especially aluminum, is the most effective, while plastic recycling is less clear in terms of energy and resource efficiency. Therefore, reducing plastic use may be the best solution.
