Carbon Negative Plastics? Using Bio-Based Carbon in a Circular Economy
Recent advances have included the inclusion of biocarbon in products that are compostable in less than 90 days, or can be fully converted back to pure carbon for re-use in a matter of minutes. The production of carbon from waste biomass sequesters three tons of carbon dioxide for every ton of biocarbon produced. This carbon can be added at up to 50% in plastics providing stiffness, color, and ultraviolet protection.
This presentation provides an overview of the opportunity to generate substantial and valuable carbon credits during the production of renewable plastics additives. Biomaterials inputs are cleaner products at competitive prices and can perform equal to, or better than, fossil fuel-based inputs. Product manufacturers that use renewable biocarbon can save money by reducing resin loading and the use of alternative fossil-based additives such as carbon black.
