The circular economy is about ensuring all waste can and is reused or recycled. A new report by McKinsey suggests that redesigning our economies to run in this way would ultimately save $340 to $630 billion per years in material costs alone. Versus the current linear economy we live in where much can’t be reused or recycled and is toxic to some degree.
It’s about minimising materials used and ensuring that those that are used don’t get so mixed up you can’t easilly reuse or recycle them.
