The reuse of glass bottles is primarily accomplished through recycling processes, where they are crushed and melted to create new glass products. This recycling method is highly effective because glass can be recycled indefinitely without losing its quality or purity. The crushed glass, known as cullet, can then be mixed with raw materials and formed into new glass items, including bottles and jars, reducing the need for new raw materials and lower energy consumption during production.

While glass bottles can also be used in various ways, such as being filled with new liquids or used as decoration, the most common and sustainable method of "reuse" within environmental practices refers to recycling and incorporating the glass back into the production cycle. Disposing of glass bottles in landfills is not a form of reuse, and while they can serve decorative purposes, this is not typically considered a wide-scale or environmentally friendly practice compared to recycling. Hence, the most accurate response to how glass bottles are typically reused aligns with the process of crushing and melting them to create new products.
