Intro

It was on a university trip that Kenyan entrepreneur Joseph Nguthiru first came across water hyacinth in Lake Naivasha.

It is an incredibly harmful and invasive weed that is currently blocking waterways and devastating fish populations all over the world.

Joseph, who was an engineering student at the time, tells us how he came up with a solution to use the plant as a material for making packaging - and how he's founded a successful business, HyaPak Ecotech, as a result.
