This is not about recycling. Not really. More about starting from where you are, with what you have.
The word comes from Latvian — tīrums, a field. A place that was once forest, cleared of roots and old growth, now open. Something grows there. Or it's just mud. It took a long time to get that way.
Paper was forest once too.
The root of the word is tīrs: clean, clear. Not sterile, more like uncluttered. The kind of clear that comes after letting stuff and baggage go.
What remains are things made slowly, from materials that already had a life.
