Implications - When a product is made from upcycled materials, it automatically has a unique selling point that the increasing amount of green consumers will appreciate. This, combined with a pleasant, clean aesthetic, will make a product truly irresistible. It simply isn't enough to have one element or another any more, prompting companies to combine the two and make a product that would still be attractive if it weren't pretty or eco-friendly.
