What's ACO? Why, that's my new name for the abaca fibers, coconut parts and olive pits that find their way into some Mercedes models. The rubberized coconut - a by-product of Brazil's coconut industry - is made into seat padding. The olive pits - also food waste - are crushed and carbonized and then used in air filters. And the fibers of the abaca plant (a kind of banana-like plant) are used as underfloor cladding of A- and B-Class cars. Newspress reminded us about the ACO products in Benz vehicles from the Geneva Motor Show, but you can get a solid background from this old post at Green Car Congress.
