Not a complete solution but I'd like to see us migrate plastic packaging back to coated paper product where possible; create pellet fuel with the used material. Paraffin coated paper makes a heck of a (clean burning) stove fuel. There would be plenty of both supply and demand.
Maybe I am callous but I doubt I would spend a lot of capital on anthropological climate change mitigation.
You are not alone.
Existing power production will get more efficient and clean over time anyway, and bringing clean, modern, nuclear on board as part of the package is nearly a necessity if you want inexpensive power to support a large number of electric vehicles. It’s certainly better than solar/wind as an economic means to generate power.
Throwing money down some pipe dream of combating climate change is insanity. It exists to excuse the third world and their pollution while destroying the quality of life of the developed world, while the left enjoys the money and virtue signaling.
I love hearing articles about ways researchers have found to break down plastics, using either microbes, or new processes which are more energy efficient.
I honestly think funding that type of research would be a much better return on investment. It would likely advance our knowledge in materials science and engineering significantly and might be very useful to space programs other future endeavors.
Wouldn’t it be amazing if the USA could be paid by countries around the world to process their trash to produce new raw materials.
