My former employer had a bag where we could recycle milk bottle tops (UK milk bottles are glass with an aluminium foil top and are delivered to the doorstep).
I saw many of my colleagues washing the tops in copius amounts of hot water before throwing into the bag. Question. What's the energy saving in recycling 10cm2 of aluminium foil compared to say heating say 500ml water to 40C?

It does bring the whole thing into perspective, doesn't it ? Good point. Oh - 2 points.

I don't know why they are washing up the bottle tops. The aluminium smelter who receives these bottle tops (together with all kinds of other alu scrap like soft drink cans) will run the scrap metal trough a cleaning bath anyway.....
And then it is thrown into a 700 degreeC oven....who cares about some drops of milk...?!

It relies upon on their sorting kit. If the cartons are capped, the presses ought to have spikes to puncture the cartons till now pressing them or the air tension could face up to till the burst potential of the carton ensuing in injury to the presses and ability injury to the staff. additionally the cartons must be chopped till now sorting as a fashion to chop up the plastic from the cardboard. no longer all recycling centers have the comparable kit. I oftentimes uncap all bins yet throw the caps into the bin.

dunno really. all i know is that when i used to have milk delivered i would wash the tops in the washing up water - saved using more water - and gave them to the local primary school to use when they make pictures and stuff.
