Is pittmoss a replacement for peatmoss?

Hi All,
There have been concerns about using peatmoss, so people started switched to coco coir. There have been concerns about coco coir, and now I hear of people switching to pittmoss. I just finished listening to a Joe Gardener podcast on Pittmoss, and it sounds promising, though I have not dug into it yet. This is a manufactured product using organic paper sources to create a peat free growing medium.

Is anyone familiar with this product? Could this be an alternative to peatmoss and coco coir? I'm wondering how it would do with soil blocks. I recall a couple people here on Permies were looking for ways to make soil blocks without peatmoss. Maybe this is it?

How exciting!

I was unaware of this product, but I would be curious to see what/how they start the process into making Pitmoss. I browsed their website and their use of the term 'organic' seems to be a little free and loose. I'll hold my judgement for now but if anybody finds information on their production process I might be able to chime in with some papermaking knowledge.

I've seen promotion of wool pellets (and also mats of felted wool, and fleece in general) for gardening use in part as a peat moss alternative. There's lots of wool that goes to waste from sheep bred more for meat and dairy purposes, and the dirtiest parts of any sheep. The wool pellets are a particularly good use of the dirty bits (extra nutrients from plant matter and sheep poop) and get heat treated as part of the process to kill any weed seeds and pathogens.

You can get low grade sheep fleeces for free or cheap if you can pick it up from a sheep farmer - sometimes they resort to burning them. Or if you know someone who spins (or felts) and starts with raw fleeces you could ask them to save the bits that they "skirt" out.
