The plant is fully operational and designed to produce both mash and pelleted feed.
The latest commitment follows the US$270 million National Poultry Transformation Programme, formalised in August with four investment partners.
Thailand’s fast-growing pet food industry and position as the world’s second-largest exporter make it a key growth market for Purina.
The investment will expand production capacity, meet growing demand and strengthen supply resilience in growing feed markets.
The project will be the largest aquaculture installation of Coldep’s Vacuum Air Lift (VAL) technology delivered worldwide to date.
The facility will separate fresh grass into a protein-rich juice stream and a fibre-rich press cake.
The agreement spans feed, hatcheries, farming, processing, cold chain and distribution.
The company had previously announced plans to acquire 65% of EL.VI.Z, with a further 35% stake planned to be acquired within three years.
The site is the company’s first ground-up factory in more than 50 years.
The acquisition expands access to local grain and strengthens Kalmbach’s feed, pet food and ingredient operations.
