I’ve been thinking about postconsumer waste lately (apparently, I have too much time on my hands). What I was wondering was this:
Postconsumer waste is only one of three waste streams for unused paper. There is also mill broke (scrap collected at the mill and recycled back into the same type of paper from whence it came); and there is pre-consumer waste (paper trimmings and other scrap collected at the printing or converting site and recycled back to the mill before reaching the hands of the consumer).
So here’s what I’m wondering. Both mill broke and pre-consumer waste are recycled back much earlier in the process, so they require less energy to transport. They also need less processing in most cases because they have not yet been printed, glued, laminated or otherwise converted. Post-consumer waste, on the other hand, has to be collected from millions of individual homes and businesses around the country. Then it has to be sorted and processed, and sometimes even bleached. The energy and processing requirements are far greater. So why is post-consumer waste considered greener?
