The composition of ashes stemming from the burning of medical waste is similar to that of urban waste. Specific pieces of evidence are looked for that allowed distinguishing some components in those waste products. A selection is carried out and some elements are included in a glass matrix. An unexpected result is presented here. It is possible to differentiate sterile and non-sterile medical gloves. The main difference is the relative amounts of calcium, in glass forming. Glasses are manufactured with a mono-ammonium phosphate since it is a natural product in Morocco. Several compositions are tried and studied. These compositions are expressed in usual two ternary and one quaternary systems built with the four equivalent components： SiO2, A1203, P205 and CaO and then compared to a patented composition.
