Hanfeng Evergreen, Inc., the largest producer of slow and controlled release fertilizers in China, has completed commissioning of the second phase of its 100,000 ton per annum (tpa) expansion of the Heilongjiang facility in China. The 50,000 tpa polymer/sulfur coated compound (PSCF) plant was completed on budget and ahead of schedule. Hanfeng announced the completion of the first 50,000 tpa sulfur coated NPK (nitrogen, phosphate, potash) compound fertilizer plant (SCF) in November 2007.
Both coating technologies, developed by Hanfeng’s own R&D team in Shanghai, allow the custom designing of various multiple nutrient blends, including micronutrients. The PSCF product, using Hanfeng’s polymer coating, provides more precise control of the releasing period for the nutrients. Although traditionally more expensive to manufacture, Hanfeng’s polymer coating process allows the company to produce and sell the PSCF at very competitive levels.
The existing Heilongjiang tower granulation plant will supply the compound NPK granules for the high-margin specialty coating plants. With the completion of the 50,000 tpa second phase, the Heilongjiang facility has 450,000 tpa of design capacity, with a full product offering that includes homogeneous granules, blended products, compound fertilizers and specialty coating products. Combined with the Jiangsu facility, Hanfeng now has 700,000 tpa of design capacity from seven plants in China.
