What is a key benefit of recycling in sanitation work?

Recycling is incredibly beneficial in sanitation work because it primarily leads to a significant decrease in landfill space usage. When materials are recycled, they are diverted from traditional waste disposal methods, reducing the volume of waste that ends up in landfills. This helps extend the lifespan of existing landfills and can even lead to the closure of new landfill sites, which can be environmentally detrimental. By recycling, valuable materials are recovered and reprocessed to create new products, which minimizes the demand for raw materials and the environmental impact associated with extraction and manufacturing processes.

The other choices do not align with the primary environmental and operational benefits that recycling brings to sanitation work. For instance, increasing the weight of waste transported or requiring more manual labor does not serve the goal of improving waste management efficiency and sustainability. Additionally, while recycling can lead to cost savings in the long run, it does not always guarantee lower expenses immediately. Thus, the key benefit of recycling in the context of sanitation work is its capacity to decrease landfill space usage effectively.
