The niche isn’t “machine to grind plastic into pellets” which already exists. The niche is “machine that sorts a bucket of random plastic waste into different types, so that when you turn them into pellets they’re only made of one type of plastic, not a random assortment which don’t melt at the same temperature and don’t bond well to one another.”

A recycling grinder into filament machine shouldn’t be that difficult to make.
