Product

The material can be disposed of by removal to
a licensed chemical destruction plant or by controlled incineration
with flue gas scrubbing. Do not contaminate water, foodstuffs,
feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and
offered for recycling or reconditioning.
Alternatively, the packaging can be punctured to
make it unusable for other purposes and then be disposed of
in a sanitary landfill. Controlled incineration
with flue gas scrubbing is possible for combustible packaging materials.

TantalumTantalum is a chemical element with the symbol Ta and atomic number 73.
Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.
Tantalum has been investigated for the treatment and prevention of Osteoarthritis, Knee Osteoarthritis, Intraoperative Bleeding, and Adolescent Idiopathic Scoliosis.
Its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers.
Tantalum, always together with the chemically similar niobium, occurs in the mineral groups tantalite, columbite and coltan (a mix of columbite and tantalite, though not recognised as a separate mineral species). Tantalum is considered a technology-critical element.
