Trending sectors for searchfund acquisition in Europe ?

Hi, I would like to brainstorm on the best sectors to invest in, considering a acquisition in a "traditional" industrial SME in Belgium / Europe ?

What are the trending sectors ?

Here are some of my ideas :

• (Houses) Insulation / window screens (global warming)
• Cooling machines (global warming)
• Water retention & storage (global warming)
• "tools" for the elderly - walkers frame, ...
• healthy food

Any other thoughts / ideas ?

Thank you for the input.

Regards,
