A huge part of sustainability is figuring out ways that we can re-use old resources to make new ones. Recycling plastic, glass, and metals is now a pretty common practice. But unfortunately, recycling plants have a much harder time sorting plastics than sorting metals and so many plastic ends up buried, burned, in the ocean or in a giant pile in a developing country. All of these things have significant environmental effects, and pose huge human safety issues for the people working in and near plastic burning facilities.
In his TED talk, Matt Biddle talked about his innovative way of sorting and recycling left over plastics. His shows us where plastics end up and how he developed a recycling plant that has lower energy costs, recycles old materials, and makes a plastic product equal to traditional plastics.
