Better Infrastructure vs. Better Tech

[unspeakablehorror]

Was just thinking about how PLA plastic is produced from plants rather than fossil fuels, fairly widely available, and both recycleable and biodegradable, but it's not currently a good solution to our plastic problem because it needs to be heated a bit in order to biodegrade cleanly and a lot of recycling centers aren't set up to process it.  This would require more composting and recycling infrastructure to support this plastic.  What I'm wondering is why issues like this aren't a bigger focus.  Is it because people lose interest in technology as soon as it becomes commonplace?  That seems to set up a perpetual problem with this infrastructure issue, where little effort is put in to improve the usage of current technology and instead the bulk of our society's energy is put into trying to invent The Next Big Thing to solve our problems which will then also have little to no infrastructure built up around it to support that technology as a solution.
