Hydrogen peroxide (H2O2) is a mildly acidic pale blue liquid that appears colorless in dilute solution. Used as bleach in the pulp paper industries, as a teeth whitening agent, laundry bleach and rocket propellant.

What goes into hydrogen peroxide

Hydrogen peroxide is manufactured by bubbling compressed air through a solution of anthracene, hydrogen gas and metal catalyst convert the solution back to anthracene after extraction of the hydrogen peroxide in a closed loop system.

Chemical contamination

Because hydrogen peroxide reacts so readily with water and breaks down quickly to form oxegen, it's not considered a toxin or harmful substance. Hydrogen peroxide can be pumped into waterways that have had slurry spills to re-oxygenate the water.

Lifetime embodied energy

Manufacture and use does not entail large quantities of energy, the biggest end user being the paper/pulp industry as a bleach.

Recycling and material recovery

Hydrogen peroxide is a simple chemical, although no material recovery is possible, as it breaks down quickly whith contact with water to produce oxegen, no impact occures from disposal into the environment.

Factoids [1]

Hydrogen peroxide is one of the two chief chemicals in the defence system of the bombardier beetle, the other being hydroquinone.
