TileGreen, which started three years ago, aims to make the country's construction industry more environmentally friendly.
So much blablabla. Where do they get it from? What "tiny shards" are that supposed to be? Why do they then mention regular plastic waste, which are clearly not "tiny shards"? How stable is the product they make (both time and force)? What can it actually be used for? Does it need new plastic mixed in? Is it going to break down to micro plastic real quick? This is pure green washing.
Seems to be a greenwashed scam I would say based on their website. Their tech document is highly suspect.

Direct Google Drive document they link.
It's downcycling into pavers and roofing tiles, which is pretty much the most you can hope for with soft plastics with today's technology.
The resulting products cannot be used for anything else after they wear out.
To say nothing of leaching chemical runoff, questionable longevity of the bricks/tiles, shedding microplastics, inconsistent mechanical properties limiting use as construction materials, etc.
This process of shredding plastics, melting, adding sand, and shoveling into molds, has been known for a long time, and there are numerous videos showing entrepreneurs in 3rd world countries using it.
Here's a video from 2015 about a downcycler in Cameroon, and it says the guy had been doing this for 15 years already back then.
Plastic waste recycling is primarily done by shedding the plastic into tiny shards. Sometimes it's even sorted by color
