| How about this information from CT's DEEP which quotes the EPA for the majority of it's information? Compared to virgin materials, using recycled materials more efficient by: - 40% for paper - 60-74% for steel and tin cans - 33% for plastics - 30% for glass - 5% for aluminum cans These numbers appear to be referencing the generation of new products using recycled vs new materials, but do they fail to take in to account the cost of actually getting those recycled materials (ie going from trash to the recycled paper pulp)? I always thought the 3 R's are in the order they are for a reason. Reduce - first step realize that happiness is not automatically linked to consumption. This is harder than it seems because this extends beyond product consumption to other forms of material consumption like traveling by plane or car (IC vs EV vs hybrid is a whole other debate) Reuse - once you have something, get the full use out of it, and try to repurpose it for other uses too if possible. Recycle - once you have used something to the point that can no longer serve it's purpose adequately because it's worn out, place it or parts of it in a recycling bin if possible. What this article and discussion has prompted me to do is research further into which parts of something deserve to be placed in the recycle bin (whether or not there is an established way to recycle them, ie plastics) and if certain reduction techniques aren't all they're cracked up to be (reusable straws and shopping bags) Reference: https://www.ct.gov/deep/cwp/view.asp?a=2714&q=440320 |
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.
