Taiwanese potassium sulfate (SOP) producer Green On has added two new Mannheim production lines totalling 20 000 tpy to its current 80 000 tpy facility, and is expected to reach 100 000 tpy of total capacity by the 2Q26.
The Mannheim process refers to the industrial method of producing SOP and a by-product of hydrochloric acid from using muriate of potash (MOP) and sulfuric acid. SOP is a potash fertilizer that is mainly used on chlorine-sensitive crops like tobacco, and certain fruits and vegetables.
Green On will flexibly allocate the total output of each grade – standard, water-soluble and granular SOP – according to market demand, the producer said.
Green On is currently working on the expansion and construction is progressing smoothly. They will need another six months to complete the planning of various auxiliary facilities of the expansion plant according to regulatory requirements in Taiwan and expects to start commercial production earliest by April 2026.
Fellow Taiwanese producer Sesoda is also planning to add capacity to its 140 000 tpy Mannheim plant. Sesoda is currently carrying out internal evaluation and has yet to announce any firm dates for reaching commercial production for its additional capacity.
