I am quite aware that everything that we use is quite expensive, so I always try to use things in a more efficient way. For example we have some special bottles with filters and they say that you can fill it up to 250 ml, but I have worked out that I can actually put 400ml in them, so I can use less bottles and there is less waste then!
Do you mean environmentally friendly? If so, then yes – all research institutes and universities will have an environmental care policy. If you really DO mean economically friendly – well, we all like saving money!
