the float glass process) and expanding uses for glass. During the 1970's, major events like the oil embargo, subsequent fuel shortages and the ensuing economic recession created a new challenge for glass manufacturers—increasing energy efficiency. The industry responded with a range of innovative products that

Executive Summary ii. Glass Manufacturing Industry industries. Manufacturing techniques vary from small electrically heated furnaces in the ceramic fibre sector to cross-fired regenerative furnaces in the flat glass sector, producing up to 700 tonnes per day. The wider glass industry also includes many smaller installations

PROCESSES AND HAZARDS. Figure 1 shows a process flow chart for manufacturing glass. Raw materials are mixed, melted, formed and heat treated to make the finished product. Scrap glass from throughout the process, called cullet, is returned to the glass melting furnace. Returning the cullet reduces waste and saves.
The grinding and polishing of flat glass to pro- duce plate glass have become obsolete since the development of the float glass process. The chemical makeup of detergents that may be used in float glass manufacturing can vary signifi- cantly—some may contain phosphorus. In blow- ing and pressing, pollutants in effluents
THE MANUFACTURING PROCESS. Glass is made from its raw materials in a carefully controlled two-step process, and is then molded to form either sheet glass or bottles. A schematic diagram of this process is given in. Figure 1. Step 1 - Batch mixing. Glass is made of different ingredients in differing proportions depending
