Mains air compressor for cleaning electronics instead of canned air?

So I was working out how to throw away my used up canned air - not an easy task in Germany with 6 different household rubbish categories plus drop points for all sorts of rubbish that the manufacturers are legally required to accept and recycle/dispose of. But it does get you thinking about waste and sustainability.
