Final answer:
The best example of a hotel using recycling to reduce its carbon footprint is implementing a composting system for food waste. This turns waste into compost, which can help fertilize gardens, thus directly involving recycling.
Step-by-step explanation:
The question asks for the best example of a hotel using recycling to reduce its carbon footprint. Among the options provided, implementing a composting system for food waste is most directly related to recycling strategies. This approach involves collecting food waste and diverting it from the landfill by turning it into compost, which can then be used to enrich the soil. By doing so, the hotel reduces methane emissions from the decomposition of organic waste in landfills, thus contributing to a lower carbon footprint.
This approach enables hotels to recycle organic matter by turning food waste into nutrient-rich compost, which can be used to fertilize hotel gardens or provided to local agricultural endeavors. While other options like offering energy-efficient lighting, installing low-flow water fixtures, and providing eco-friendly toiletries are positive green initiatives, they are not direct examples of recycling.
