There is a total energy savings compared to making new plastic, but it is only like 10-20% less energy. But that is a better solution than jusy dumping into a landfill. And yeah a plastic plant recycling material for new plastic bottles is like 16-20% recycled and the rest new material, so you need to make 4 bottles at least to consume an old one, so it is an expanding pyramid of bottles required.
