Researchers at the UPM have discovered how to produce
activated carbon from sewage sludge that can be used to purify liquids or gases
generated in various production processes.
The problem involved in gas emissions of greenhouse effect
has boosted diverse strategies of capture and storage of the most common gas
which is the CO2. A strategy used by the group of Environmental Technology and
Industry Resources of the UPM consists of the adsorption of CO2 through
activated carbon obtained from sewage sludge ("Carbon dioxide adsorption
in chemically activated carbon from sewage sludge"). The use of waste as a
raw material to produce activated carbon has a double objective: it allows us
to assess the waste as well as reducing the production cost of produced carbon.
