What is more environmentally friendly? Disposable cups or washing glasses in detergent producing waste water?
Washing glasses in detergent is far more environmentally friendly than buying disposable cups for ever time you want a drink. Most disposible cups are made from either polystyrene or plastics so their production is far more damaging to the environment than glass production. Also they take longer to break down so will be hanging around for much longer than galss will which can be re-cycled. Although you would be producing waste water by washing the glasses, the water will be recycled too as is will be treated and put back into the water system. Make sure that the detergent you use is environmentally friendly if you can (Ecover is a good one) but as long as you don’t use too much of it then it is a far better way to go.
