Does anyone know if this could be used to build high-rises? I imagine it has enough strength for a 10 story building, but the fire risk might be too high.

Cross-laminated timber is already being used for 10-story buildings today. Here's an 18-story one: https://www.dezeen.com/2019/03/19/mjostarne-worlds-tallest-timber-tower-voll-arkitekter-norway/ https://www.dezeen.com/2019/03/19/mjostarne-worlds-tallest-t... And there's a 12-story one in Portland: https://www.archpaper.com/2017/06/framework-portland-timber-tower/ https://www.archpaper.com/2017/06/framework-portland-timber-...

Contrary to what people believe, timber actually has very good fire resistance characteristics: https://csengineermag.com/fire-design-of-mass-timber-members/ https://csengineermag.com/fire-design-of-mass-timber-members... No need for densified wood to build midrises, structured timber products like CLT (basically, fancier plywood) are already being used to construct 5 - 10 story buildings with the tallest wooden skyscrapers being planned at 20 - 70 stories tall: https://edition.cnn.com/style/article/wooden-skyscraper-revolution-timber/index.html https://edition.cnn.com/style/article/wooden-skyscraper-revo...
