Steel products are needed to support the
development of the manufacturing industry and
other strategic industries in Indonesia. The
steel industry is one of the contributors to CO2
gas emissions, which contributes about 15
percent of greenhouse gases (GHG). PT. XYZ,
which is one of the largest steel industries in
Indonesia, produces CO2 waste from the
reduction process in the exhaust gas by an
average of 20 tons/hour to produce its steel.
This study aims to utilize CO2 waste in exhaust
gas into liquid CO2 so that its utilization can
reduce CO2 emissions to the environment.
Waste minimization by PT. XYZ is by recycling
CO2 waste into liquid CO2 with CO2
Purification technology. Liquid CO2 is useful
in various industries such as the manufacture
of carbonated beverages, food and beverage
preservation, and the welding industry. Waste
minimization has resulted in a 10% reduction
in CO2 emissions by an average of 10%. The
magnitude of this decrease is influenced by the
limited production capacity and storage tank
capacity. The results of the study also show
that the variables that are considered for the
use of CO2 emissions are the purity of CO2,
raw gas CO2.
