McDonald's is making strides toward providing zero-waste solutions for its disposable food and beverage packaging. Their latest change to the way they serve their beverages brings them one step closer to the goal of sourcing all of their packaging from renewable, recycled, or certified sources at all restaurant locations by 2025. The chain announced on Wednesday that they will start testing a reusable cup next year in select locations in the United Kingdom. In a partnership with recycling company TerraCycle, based in the U.S., McDonald's will provide its customers the option of choosing a durable, reusable cup for a small deposit. Once the cup is returned to a McDonald's location, it will be washed and reused, and customers will be able to redeem their deposit. Or, they can simply keep reusing their McDonald's cup themselves. This is great news for anyone concerned with the devastating impact of wasteful single-use packaging on the environment. The chain is already operating a similar program in other countries like Germany. In the U.S., while no such efforts have yet been announced, the company is involved in an open innovation initiative  NextGen Cup, a global design competition calling for best new ideas on how to create an easily scaleable and commercialized solution to the single-use cup.
