How to make plastic bottles from sugarcane and captured CO₂ #Plantastic

Bagasse harsha k r 800x536

This is uplifting research showing that plant-based plastics can economic, practical and good for the environment!

Via Ars Technica:

A new study led by Durham University’s Long Jiang, Abigail Gonzalez-Diaz, and Janie Ling-Chin lays out a pathway to making plastic bottles from waste organic material and CO2 captured from power plants. A thorough analysis of the economics shows this process could even be cost competitive for making things like plastic bottles.

The process could start with something like the leftover plant material from sugarcane pressing. After a few reaction steps, which include the addition of some captured CO2 and some ethylene glycol produced from corn plants, you’d end up with a plastic polymer called polyethylene furandicarboxylate—otherwise known as PEF. Functionally, it’s similar to the PET plastic used for water and soda bottles, denoted by the number 1 recycling symbol.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
