manufacturing companies in California vary in size and range from small privately held companies to large
multinational corporations. There are
four major segments in the glass manufacturing industry which are separated by
the type of end products generated.
These segments include container glass, fiberglass, flat or float glass,
and pressed or blown glass (also known as specialty glass). Production and consumption
for all four segments of the glass manufacturing industry are often concentrated
near U.S. population centers due to very high shipping costs of both raw materials and
products, and the heavy concentration of end‑use customers.
The container glass segment produces bottles, jars, and other containers
that compete with alternative materials such as plastic, aluminum, steel,
and paper. Most of the market for the flat
glass segment is comprised from residential and construction, and
automotive industry products. Other
products from this segment include mirrors, instrumentation gauges, and architectural
items such as table tops and cabinet doors.
The fiberglass segment is composed of two distinct
sub-industries: insulation, which is often referred to as glass wool, and
textile/reinforcement fibers, which are continuous fiber strands used to reinforce plastics
and other materials important to the transportation, marine, and construction
industries. The specialty glass segment
is very diverse and consists of traditional products, such as lighting,
cookware, and television glass components along with newer products
such as fiber optics, photonics, flat screen displays, and liquid crystal
There are federal regulations on the glass manufacturing industry that
regulate the emission of toxic air contaminants (TACs) and/or criteria
districts have either incorporated these regulations or have been granted equivalency and
given authority to implement district rules to reduce emissions of criteria
pollutants and TACs from fiberglass manufacturing plants and criteria
pollutants from all other glass manufacturing plants.
In addition, California
Beverage Container Recycling Program (CA
Beverage Container Recycling & Litter Reduction Act) and
Fiberglass Recycled Content Act
of 1991 require glass container
manufacturers in California to use at least 35 percent cullet (recycled
glass) in their products and fiberglass manufacturers that manufacturer or sell
in California to use at least 30 percent cullet in their products. CalRecycle, officially known as the Department of Resources Recycling and Recovery, is the agency that implements the California Beverage Container Recycling Program and the Fiberglass Recycling Content Act of 1991.
