An oxygen-fuel burner for a glass-melting furnace generally includes a first (or inner) conduit for fuel, a second (or middle) conduit for waste glass cullet, and a third (or outer) conduit for combustion oxygen. The first, second, and third conduits are nested and define respective paths for fuel, cullet, and oxygen flows. A cullet supply funnel is coupled to the second conduit such that cullet can be introduced into the second conduit through the funnel. Organic contaminants in the waste glass cullet are incinerated in an almost pure oxygen environment proximate where cullet particles exit from the burner and prior to reaching the glass surface below.
