A carbon dioxide scrubber is a device that absorbs carbon dioxide. It is used to treat exhaust gases from industrial plants and life support systems in spacecraft, submersibles, and sealed chambers. Carbon dioxide scrubbers are also used in controlled atmosphere storage.

1. A carbon dioxide scrubber is a device which absorbs carbon dioxide (𝑐𝑜2
). It is used to treat
exhaust gases from industrial plants or from exhaled air in life support systems such as
rebreathers or in spacecraft, submersible craft or airtight chambers. Carbon dioxide scrubbers are
also used in controlled atmosphere storage.

2. What is released from car
exhausts
• The major products of the complete combustion of petroleum-
based fuels in an internal combustion engine are carbon
dioxide and water, with nitrogen from air comprising most of
the remaining exhaust. A very small portion of the nitrogen is
converted to nitrogen oxides and some nitrated hydrocarbons.

3. Carbon scrubber in car exhaust
system
• The CO2ube attaches onto the end of your tailpipe using
hose clamps. A combination of algae and sodium
hydroxide filters out the carbon dioxide as it exits from
car.
• A single CO2ube is going for a pledge price of $45. The
company behind the product, Ecoviate, has created
working prototypes and is looking to produce the device
in quantity. A smartphone app is also intended to
accompany the CO2ube. The app would let you track
your emissions over time.

scrubber work

6. Advantages of the 𝒄𝒐𝟐
Scrubber
• A 𝑐𝑜2
scrubber can help protect the economy by diminishing the need to reduce the
use of fossil fuels, which remain less expensive than renewable and alternative
energy source.
• Finding ways to reduce carbon in the atmosphere, some argue, is simply pragmatic,
because most consumers and corporations are not willing to reject fossil fuel use.
• Using a 𝑐𝑜2
scrubber will reduce the amount of greenhouse gases that lead to global
warming.
• It is estimated that the amount of carbon in the atmosphere is nearly 40 percent
higher than before the Industrial Revolution, so some environmentalists argue that
scrubber technologies are needed regardless of advances in alternative energy
sources.
