Manufacture of glass and glass products

NACE v2.1 Code: C23.1

About manufacture of glass and glass products

NACE code 23.1 covers the manufacture of glass and glass products, a critical industry that plays a vital role in the global economy. Glass production is a centuries-old process that has evolved significantly, providing a wide range of materials essential for various industries, from construction and automotive to healthcare and consumer goods. This industry's importance lies in its ability to supply high-quality, versatile, and sustainable materials that contribute to the development and advancement of numerous economic sectors.

Production process

The primary production techniques used in the manufacture of glass and glass products involve the melting of raw materials, such as sand, soda ash, and limestone, at high temperatures. The molten glass is then shaped using various methods, including blowing, pressing, and drawing, to create a diverse range of products, from flat glass and containers to fiberglass and specialty glass items. Advanced technologies, such as automated production lines and computer-controlled processes, have further streamlined the manufacturing process, improving efficiency and quality.

Production inputs

The key inputs required for the manufacture of glass and glass products include raw materials like silica sand, soda ash, limestone, and various other minerals and additives. Additionally, the industry relies on specialized machinery and equipment, such as furnaces, molds, and cutting tools, as well as a skilled workforce capable of operating these complex systems.

Production outputs

The primary outputs of the glass and glass products manufacturing industry include a wide range of products, such as 23.11 Manufacture of flat glass, 23.12 Shaping and processing of flat glass, 23.13 Manufacture of hollow glass, 23.14 Manufacture of glass fibers, and 23.19 Manufacture of other glass, including technical glassware. These outputs are then consumed by various other industries, including 41.2 Construction of residential and non-residential buildings, 29.3 Manufacture of parts and accessories for motor vehicles, and 32.5 Manufacture of medical and dental instruments and supplies.
