Hotels supply utensils and containers to guests for room service. Offering non-disposable containers and utensils provides quality service without the waste. Non-disposable containers and utensils can be used, washed, and then re-used for many years.
Non-disposable items reduce waste because they are not thrown out after use. The items may have a higher up-front cost, but over time they may return a savings since hotels will not have to purchase and restock disposable items. Many guests also prefer to be served on china/ceramic and use metal utensils rather than plastic or paper because it imparts a sense of superior quality.
