The refurbishment and modernisation of fertilizer plants offers the opportunity to reduce operating costs, raise production capacity, improve energy efficiency and cut emissions.

A selection of innovative products and technologies that have recently been brought to market.

Wet process phosphoric acid plants require reliable cooling water facilities. Jan Tytgat, engineering manager, De Smet Agro, shares his insights on the design and operation of cooling water networks, pumps and towers.

The phosphate fertilizer industry is turning to production methods that are able to consume low-grade phosphate rock and/ or generate pure gypsum as a by-product. Gypsum-free processes, and technologies that capture phosphorus from waste streams, are also on the rise.

Reclaiming phosphorus from sewage sludge ash holds great potential for the fertilizer industry – by helping to reduce dependency on global supply chains, ensuring resilience and even raising quality. But successful phosphorus recovery largely depends on the process used, as EasyMining’s Anna Lundbom, Sara Stiernström and Christian Kabbe explain.
