摘要

The chemical composition of container glass has evolved over many years to become almost generic, providing a material which fits its purpose very well and is a cost effective form of packaging. However the melting of glass is an energy-intensive process which is becoming increasingly expensive. The process also has a significant environmental impact, with the creation of carbon dioxide (CO_2), nitrogen oxides (NO_X), sulphur dioxide (SO_2) and particulates. Thermal NO_X is very temperature sensitive, particularly at the high operating temperatures in a glass furnace. A glass furnace with a crown temperature of 1600 deg C will emit around 2400mg/m~3 thermal NO_X, whereas one operating at 1500 deg C will emit only 1500mg/m~3 - reducing NO_X emissions by nearly 40 percent. If and when a European carbon tax is introduced, this will add to the growing number of factors pushing the glass industry to re-evaluate glass formulations. This must be done with a view to lower energy consumption and lower environmental impact.
