Suzano is the largest pulp and paper company in Latin America and a leader in the paperboard market. The company is also the world’s largest producer of eucalyptus pulp.

The ANDRITZ ARC plant removes the harmful chloride and potassium from the ElectroStatic Precipitator (ESP) ash and returns valuable chemicals to the chemical recovery cycle. The plant to be supplied is designed to handle 550 tonnes of ESP ash daily.

Featuring new energy recovery technology, the ARC plant will optimize energy efficiency significantly. This technology is also based on an enhanced evaporative crystallization concept that will improve the recovery process.

According to ANDRITZ, this order, the value of which has not been disclosed, is demonstrating the company’s “strong global position” in the supply of state-of-the-art and environmentally friendly ARC plants.

The estimated start-up date for the ARC plant is the first half of 2022.
