Plastic has long been made from oil, but today it’s increasingly made from ethane, a component of natural gas. To turn ethane into the building block of plastic, petrochemical companies are investing in ethane cracker plants, raising concerns about what these facilities could mean for air pollution and climate change.
Leaks of methane from gas and oil wells are a major source of climate pollution but it’s tough to detect the odorless and colorless gas. Now, a new competition is spurring inventors to come up with cheaper and more effective methane detectors. The World’s Jason Margolis profiles two of the inventors.
