Methanex Corp. has begun producing methanol from its 1.1 million-ton plant in Geismar, and expects to ramp up to full production in the next few weeks.

The plant successfully produced methanol, used in making plastics, on Jan. 24. Methanex moved the plant from Punta Arenas, Chile.

The startup marks another key milestone in the company's plan, announced in 2013, to grow capacity by approximately 3.3 million tons over three years, said John Florien, president and chief executive officer. Methanex also is making progress in the construction of its second Geismar plant. Production at that 1.1 million-ton facility should begin in the latter part of the first quarter of 2016.

The Geismar 1 plant was completed over roughly a 2½-year period. The estimated total cost for the completion of the two Geismar plants remains about $1.4 billion, Florien said.

Methanex is a Vancouver-based, publicly traded company and is the world's largest producer and supplier of methanol to major international markets.
