sorry if this is slightly off-topic...

but as I was watching the CBB housemates building the Lego Wall
my mind wondered to the topic of plastic recycling.

Only a few types of plastic can be recycled and the rest go to landfill and
I was wondering if instead the plastics can be melted down into Lego style
bricks and then sold off (Lego is still very popular). The funds receive could then be invested into recycling projects.
