General The PHILPHOS fertilizer plant is the Philippines leading producer of phosphatic fertilizer and has one of the largest processing capacities in the ASEAN region with a rated capacity of approximately 1.17 million metric tons per annum. The complex covers an area of 128 hectares within the 435-hectare Leyte Industrial Development Estate (LIDE) in Isabel, Leyte, the largest industrial estate in the country.  Isabel, Leyte is the ideal site for the fertilizer complex because of the abundant energy supply (very near to the Tongonan Geothermal Power Plant), its deep natural harbor, and its convenient location in the central region of the Philippines.

News June 13, 2018 - The Philippine Phosphate Fertilizer Corporation (Philphos) will start on July 1st the rehabilitation of its plant complex in Isabel, Leyte which was totally damaged by super typhoon Haiyan locally known as Typhoon Yolanda in 2013.  Philphos Chairman Salvador Zamora made the disclosure following a successful talk with Dubai’s G.S. Gupta, Chairman of Agrifields which agreed to invest USD150-million to kick-off the rehab plan. Zamora revealed that the entire complex of Philphos was re-insured by the Lloyds of London for USD300-million but that only USD150-million had been released so far.  Philphos was the biggest phosphate producer in Southeast Asia with an output of not less than one metric ton annually.  The rehabilitation, Zamora said, will be completed early 2019. More than 400 employees were displaced following the devastation caused by Yolanda. He expects to employ some of them as laborers during the rehabilitation and then employ them once the plant goes back to normal operations.  Zamora said he was motivated to revive the project because of the support that the Duterte administration is giving to farmers. He said that while Atlas Fertilizer of Cebu produces phosphate the country now resort to importation to augment the shortage. He said that Philippines used to be the biggest phosphate fertilizer exporter.  Philphos makes use of the sulphuric acid which is the byproduct of Philippine Aluminum Smelting & Refining (PASAR) Company which is also based in Leyte. Zamora explained that PASAR spends USD15-25/ton to get rid of sulphuric acid.  “We will erase these negative trade," he said.  Zamora added that phosphate production has its byproduct which he, and a probable Chinese partner will manufacture into a strong construction component that would drastically bring down the cost of socialized housing under the Duterte administration. No details had been mentioned except that there is an ongoing talks with a China group on this one.  www.pna.gov.ph

March 6, 2014 - Nearly four months after typhoon Yolanda (Haiyan) hit Eastern Visayas, hundreds more workers suffer job loss and forced leaves as companies fail to resume operations due to power outages or ongoing repair.  Around 350 contractual workers in PHILPHOS were retrenched in February this year as the fertilizer-producing company is still unable to operate due to power shortages. Over 1,000 contractual and regular workers of the same company were forced to take leaves on rotation while operations are still at a halt.  PHILPHOS, one of two major fertilizer companies in Isabel, Leyte was severely devastated by Typhoon Haiyan on November 2013; all of its 12 plants were completely damaged. While there have been repairs in the factory, the power supply in the province is very low as the Tongonan Geothermal Plant in Cananga, Leyte is still under repair and will be finished on August this year.  According to the PHILPHOS local union President, Pelagio Galban, the company targets to re-open only one of its 12 plants on April which may ease the job situation as some workers can go back to work. But until the company can fully operate, most of the workers are in precarious condition.  “It has become extremely difficult for workers to cope with the damages to property and subsequent job loss wrought by Typhoon Yolanda. Job opportunities in PASAR (another fertilizer company in Isabel) and in rehabilitation projects are mostly for skilled laborers. If you are an ordinary worker like what most of the contractual workers are, it will be  really harder to land on jobs,” Galban explained.  Galban also said that while some workers used to live in farming communities, they have already abandoned their farms in the countryside to become wage workers so they cannot easily go back to the farm, apart from the fact that farming communities were also devastated by the typhoon.  Galban also expressed fear that the situation might worsen if PHILPHOS suddenly declares bankrupcy. “We were scheduled to have a collective bargaining agreement this week but because of the stoppage our negotiations is also hanging. All we can do now is hope that the situation will become better.”  Meanwhile, another 60 workers in Tolosa Oil Mill Inc (TOMI). in Tolosa, Leyte were affected by the company’s temporary closure due to ongoing rehabilitation. Twenty-five of these 60 workers were already terminated while the rest are still fighting to be able to go back to work when the company resumes operation.  Arman Hernando, Documentation Coordinator of Center for Trade Union and Human Rights, expressed the same worry as workers’ welfares and rights are not well-protected whenever natural disaster occur. “While it is true that some companies may incur losses due to typhoons and flooding, sometimes these natural disasters are also being abused by some capitalists to declare bankruptcy to the detriment of the workers.”  Hernando said that some companies in the past have used disasters as opportunities to remove regular employees or bust unions and resume operation with a new set of workforce that are all unorganized and contractual. “It is good PHILPHOS has not totally closed down, but we cannot stop worrying especially now that hundreds of workers have already been displaced.”  The group urged the government to do something to protect the workers’ job security in times of disaster and not just the businesses.
