Moss as a fine dust filter: Liam Kastner’s ingenious invention

Mosses can filter fine dust from the air. The student Liam Kastner is fascinated – and uses the effect for his start-up.

My most important insight from the past few years is: just start building! Just start and take the first step. This is how my project for Jugend forscht became a start-up. In the summer I will sell the first moss filters, there are already 300 customers on the waiting list for the “Mozz”.
