State-owned Indonesian cement producer PT Semen Tonasa has begun construction of a new 300,000t capacity packing plant in the Belang Belang port area, Mamuju District, West Sulawesi.

Speaking at the inaugural ceremony to launch construction of the IDR100bn project, Tonasa's president director, Unggul Attas, said the plant is being built in cooperation with PT Latanindo Graha Persana and is expected to be completed in a year.

He said that demand for cement in West Sulawesi was high so that PT Semen Tonasa which was based on South Sulawesi`s pangkep District, decided to build the plant in West Sulawesi.
