US technology firm UXB International says it has helped successfully destroyed lethal chemical weapons in Libya.

Toxic arms, which include artillery shells and aerial bombs, have been “eliminated” by a system supplied by UXB and subcontractor Dynasafe International to Californian engineering firm Parsons Corporation, according to a press statement.

In the statement, UXB says 1.6 metric tonnes of weaponised sulphur mustard within Libya’s declared chemical weapons stockpile was disposed of.

UXB describes itself as a global environmental technology and response solutions company with core business in military munitions, explosives, and reactive chemical support services.

”The successful completion of this project represents a significant milestone in international efforts to destroy chemical weapons stockpiles around the world,” said UXB International CEO Richmond Dugger.

“UXB is honored to be a part of this project and is pleased to have the opportunity to demonstrate our unique solutions for the elimination of chemical weapons hazards within recent theatres of war. We hope that this successful project will be used as a template for similar projects in the future.”

In particular, UXB explains in a statement that it delivered a “customised and transportable static detonation chamber (SDC)” for the destruction of the chemical weapons on 26 January, 2014.

Libya is recovering from a violent 2011 civil war that led to the ousting and killing of former Libyan dictator Muammar Gaddafi.

However, this year two Libyan militias have called for the country's legislators to step down or be detained, sparking fears of instability in the country again.
