Recycling is really less necessary than it would seem. There are >50 escape rooms in Warsaw. If I visit one every two weeks, I'd start running out of options only after two years. Going to escape room twice a month is pretty often anyway...
I didn't realise that one city's market could be large enough to support that many. In Vancouver I've only seen 5-6 of them, and in Mumbai where this just started, I only know of one company running them. Yes, if you have >50, recycling won't be a problem.
