The PR re Sustainable Aviation Fuel (#SAF) continues. And this article touches on some of them - such as is there enough waste cooking oil to support the need at today's demand for flying.

But there is another demand issue: If we want to dramatically reduce fossil C extraction (esp oil), then we need substitute feedstocks to supply the feedstocks for critical chemical processes. Waste cooking oil and other food and organic waste may well be the best source - if we can convert it to SAF, we can convert it to useful chemicals that now come from oil. Yet there is not enough organic waste to support SAF demand, let alone for all the paints, lubricants, polymers, medicines, ... we rely on. (And if we continue to insist on wasting resources on single use plastics, such as PET food and beverage packaging, the problem is even worse)
#FalseClimateAction is a threat, and SAF is likely in that category as a long-term strategy.
