Thailand: TPI Polene, Thailand's third-largest cement maker, plans to spend US$341m from 2013 to 2016 to develop a new production line at its Saraburi cement plant and to expand into renewable energy.

The project has been postponed since the financial crisis in 1997, said chief executive Prachai Leophairatana to the Bangkok Post. The fourth line will be developed at TPI Polene's existing plant in Saraburi province for US$194m. Production capacity will be raised by 33% to 12Mt/yr by 2026, making it the largest cement plant under one roof in the world.

"TPI Polene is the first Thai cement maker to invest in capacity expansion since 1997," said Prachai. "We saw cement demand gradually recover over the past few years. Additional demand will come from from the government's train projects over the next seven years."

TPI Polene has signed a memorandum of understanding to develop the project with Belgium firms P&V Project (Siemens), ALC Tournai, Atlas Copco and Magotteaux.

Thai cement exports from all producers are expected to come to 7Mt in 2013, down by 30% from 10Mt in 2012. TPI Polene aims to trim its exports to 700,000t in 2013 from 1Mt in 2012.

The company is also preparing to develop a 90MW unit fuelled by community waste, pending an environmental review. Around 60 MW from the new plant will be sold to the Electricity Generating Authority of Thailand, with the rest consumed in-house. The company also plans to generate additional revenue from the new power plant via sales of carbon credits under the Clean Development Mechanism concept.
