About clays

cpc code 154 covers the industry of clays, which are naturally occurring, fine-grained, earthy materials that are widely used in a variety of applications. Clays play a crucial role in various industries, including ceramics, construction, and manufacturing, making them an essential component of the broader economy. The extraction and processing of clays are vital activities that contribute to the production of a wide range of products that we use in our daily lives.

Production process

The production of clays typically involves the extraction of raw materials from clay deposits, followed by various processing steps. These may include crushing, screening, washing, and drying to remove impurities and prepare the clay for its intended use. Depending on the specific application, the clay may undergo further processing, such as blending with other materials or firing at high temperatures to enhance its properties.

Production inputs

The main inputs required for the clay industry include the raw clay materials, which are sourced from natural deposits. Additionally, the industry relies on specialized equipment and machinery for the extraction, processing, and transportation of the clay. Energy sources, such as electricity or fuel, are also necessary for the various stages of production.

Production outputs

The primary outputs of the clay industry are the processed clay products, which are then used as inputs for a wide range of industries. These include the 201 Ceramics industry, the 202 Glass and Glass Products industry, and the 203 Cement, Lime, and Plaster industry, among others. The specific applications of clay products can vary widely, from the production of bricks and tiles to the manufacture of advanced ceramic materials.
