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 bagQuestionWhat'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 pointOh - 2 points.
