PQ Corporation products are utilized in the NETL (National Energy Technology
Laboratory) Carbon Sequestration Program in order to capture and store carbon
dioxide (CO2) in an effort to reduce greenhouse gas emissions. The technologies
of carbon sequestration capture and store CO2 that would otherwise reside in the
Earth's atmosphere for long periods of time. PQ Corporation is committed to this
and other comprehensive manufacturing and energy efficiency initiatives.

PQ silicates are non-toxic and one of few oilfield chemicals that can be beneficial
to the environment both on-land and offshore. Potassium silicate is a source of
soluble potassium and soluble silica and in many countries PQ potassium silicate
is registered as a fertilizer. On-land, this makes potassium silicate a natural choice
for drilling. Offshore, sodium silicate is preferred. When discharged into the sea,
the soluble silica aids in diatom growth.
