Milk can be delivered in plastic bottles, glass bottles, or paper cartons. We preclude from using the latter two because the glass bottles are considerably heavier than plastic ones. So if we can deliver 2000 liters of milk in plastic bottles in a single vehicle we'd require 4 such vehicles to transport the same quantity in glass bottles; thus killing the motive entirely as it will have a much larger carbon footprint. In the case of paper cartons, the walls of a paper carton micro-perforations & thus chances of contaminant seeping through are much higher. 

Yes, Provilac uses BPA-Free PET bottles that are highly inert, thus, able to maintain the goodness of milk till it reaches your doorsteps. 

Yes, Provilac plastic bottles are recycled; all you have to do is leave the milk bottles outside your door where the milk gets delivered. Our delivery executives are trained to take them back to our facilities from where they are sent for recycling.

While there is no difference in the product, milk bottles are convenient while storing in your refrigerators and are easily recyclable.
