So can plastic truly be recycled? Let's break it down, plain and simple...
Materials like metal, glass and paper can truly be recycled because they can be remade into the same form without needing any additional materials to do so. A recycled glass container can be continually remade into a glass container, over and over and over again, without ever needing new material and without ever needing to go to the landfill.
Plastic on the other hand, cannot be. The process of recycling plastic weakens it, so new, virgin plastic must be added to it in order to make the same form again. Essentially, plastic can be DOWN-cycled but not truly REcycled. For example, a recycled plastic water bottle can be down-cycled into teddy bear stuffing or a synthetic rug, but not into another water bottle without needing to add new plastic. And eventually, this down cycled plastic will run it's lifecycle to the end and will end up in the landfill.
So now you can see why recycling is definitely not the answer. Not much of plastic gets recycled anyways, and that which does, is destined one day to end up in the landfills or waterways. So what is the answer??? Refusal! Not using it at all, and instead, finding a truly sustainable alternative that can be reused, recycled or will biodegrade and return to the earth one day.
