I wish to protest about the introduction of a more complicated method of waste collection which, in my opinion, would create a greater degree of confusion and contaminated waste and therefore not solve the problem it was intending to alleviate. More expense would be needed and wasted on additional boxes which would possibly required resorting due to the number segments required.
My only consideration would be to enable one simple addition of a separate box for "glass only" which could not be confused with other types of materials and therefore easy to understand and achieve a result.
