Until stated otherwise, I'm going to assume these paper bottles will be plastic-lined, like milk "cartons", and so just as non-biodegradeable and non-recyclable

Until stated otherwise, I'm going to assume these paper bottles will be plastic-lined, like milk "cartons", and so just as non-biodegradeable and non-recyclable. Most of the time I've seen a switch from glass to plastic or "not plastic", the real reason is to cut down on product loss due to glass breakage en route, which is pretty big.
