European scientific decision-making is often overtly political and that can lead to decisions which defy common sense.
Case in point; disposing of food waste.

In some countries they can.
There is no way for science to Brexit so companies, researchers and even pro-science politicians remain stymied in parliament-style governments, which must cater to numerous constituencies, often in conflict with each other.
