Are NWPP bags really environmentally friendly?
The term ‘environmentally friendly’ implies that polypropylene leaves no ecological footprint. NWPP is manufactured in factories using fossil fuels, and so contributes to greenhouse gas emissions. However, the evidence above combined with the fact that polypropylene contributes to waste reduction and the movement away from one-use products, means that its ecological footprint is smaller than that of similar alternatives. Please make the effort to recycle polypropylene bags where facilities are available. http://archive.greenpeace.org/toxics/pvcdatabase/bad.
