There is so much wrong with this I don't know where to begin... lol
We need to attack the root of the problem, not cover it up. The issue is that we are using processes to create materials that are harmful to the planet. There are other processes that create "green" materials that are biodegradable. They just cost more, and everything boils down to economics.
We need to improve upon our recycling programs, and rather than trying to get rid of our "waste" we need to reprocess it and use it again. If we keep throwing everything into outer space, eventually we will not have enough raw materials to continue supporting the growth of our planet.
We have created this concept of trash, and it is so accepted in the minds of everyone that we don't think twice about it. We need to focus on solutions to cutting down on the creation of waste and more into recycling. Recycling takes a lot of energy, but if that were obtained through fusion or solar energy, we would be on the right path.
