[step] Glass bottles come in a variety of colors, from clear to brown to green. Clear bottles are used the most and are made of sand, soda ash, and limestone. <sep> (A) Brown and green glass bottles are usually used for drinks like wine and beer. Clear, brown, and green glass bottles can all be recycled. (B) [substeps] Be wary about putting clear plastic cans or glasses in the recycling pile. This is how plastic is collected and recycled. (C) Green bottles come in different finishes, including paint and enamel, and are full of dirt.

(D) Rain, ice, or heat can also affect glass bottles' surface quality. [substeps] You can recycle glass bottles by passing the glass bottle's case to a local recycling company that will collect them for you.
