Final answer:
The synonym for 'dross' is trash. The term refers to municipal solid waste, which encompasses various types of everyday discarded items. Proper waste management, including recycling, is crucial for minimizing landfill usage and protecting the environment.
Step-by-step explanation:
The synonym for 'dross' in the context of the question is trash. When communities discuss how to dispose of dross as landfills are filling rapidly, they are dealing with the ever-growing challenge of municipal solid waste (MSW) disposal. MSW, commonly called trash or garbage, includes everyday discarded items from households and businesses. The waste stream mainly consists of inert wastes like plastic film and non-recyclable packaging materials, especially where effective recycling systems are not in place.
Reducing, reusing, and recycling solid waste are pivotal in managing the volume of waste in landfills and incinerators, thus promoting a safer and cleaner environment. However, with landfills reaching capacity and concerns about groundwater contamination, alternative waste disposal methods such as waste-to-energy processes are gaining attention.
Although these methods produce energy, they share environmental impacts similar to coal plants, like air pollution and ash generation. Hence, local recycling authorities play a crucial role in informing residents about proper waste separation to ensure materials are either recycled or disposed of correctly.
