Most plastics are made entirely from fossil fuels. Every year the plastics industry consumes as much oil as the entire aviation sector and that amount is growing. As a global population, it is critical we move away from a reliance on these fossil fuel content and increasingly on renewable and recycled materials. We define renewable materials as being sourced from material streams that regenerate consistently on a human time scale and can be sustainably managed. Trees, crops, and other organisms that derive their energy from the sun are considered renewable, and in accordance, paper pulps are also considered renewable. In order to move towards a functioning circular economy and reduce carbon emissions it is critical that we move towards systems that mimic the natural world.
