Packaging is all around us — different types of plastics, paper, glass, metal and other materials help contain innumerable products and substances. Unfortunately, much of this packaging is considered disposable, and even if it's recyclable, it often doesn't end up recycled. Additionally, some of the materials used in packaging contain harmful elements (specifically plastics). Many companies have worked to provide eco-friendlier packaging, which helps reduce waste, improve efficiency and prevent exposure to chemicals. (Photo: Flickr)
