It's not clear to me from that link whether those savings apply to the whole supply chain or not.
So when they say stuff like... "Producing recycled paper requires about 60 percent of the energy used to make paper from virgin wood pulp."
... does that include costs of reasonably sustainable forestry vs. reasonably sustainable old paper separation & collection?
... does it include non-financial costs made by the end-users of the original paper?
... does it include implicit costs of potentially lower quality paper (or if that's ever the case, the values of higher-quality)?
... does it include the opportunity costs (probably small) of whatever else you might do with that old paper, such as sequester carbon or burn for energy?
... does it consider costs of energy (some joules are cheaper and less damaging than others; so e.g. it may be wood->paper factors run where energy is trivially cheap and simply haven't bothered to try and be energy-efficient)?
... does it consider non-energy resources?
Basically, it's not clear to me whether this is a technical argument about one of the important steps in the respective processes, or an overall assessment about the approaches going forward.
