This is the common site in India when empty bulk pack containers are transported. Can we think of a bettr way to transport these? They simply transport air and burn energy. If these need to be recycled, may be companies can crush & compact them. This would also reduce their improper use like many a times such chemical containers are used to transport drinking water too. What do you say? This is the picture I took in Hyderabad. Thse are also quite dangerous for the safety on roads. And we do not want our packaging to cause accidents, do you?
