General

Formed in 1976, the company actively pursued the construction of the plant in Leyte which was completed in 1983 to signal the Philippine Government's industrialization plans for the country. PASAR's primary product is electrolytic copper cathodes, the raw material used for manufacturing various kinds of electric cables, telecommunication wires, copper shapes and copper-alloy products. The PASAR Copper Cathode is registered as Grade A Copper in the London Metal Exchange (LME) and as COMEX High Grade Copper in the Commodity Exchange (COMEX) Division of the New York Mercantile Exchange (NYMEX). It is also listed in the Shanghai Futures Exchange.

The location of PASAR copper smelter and refinery in Leyte in the central Philippines has resulted in many advantages for the company and its partners. The port possesses a deep-harbor facility which is being reconstructed to berth and handle vessels up to 50,000 DWT. It lies in the center of the Philippine archipelago, ready to serve the smelting needs of the country's reviving mining industry.  The complex includes pollution abatement facilities; port and bulk handling facilities; an airstrip; a medical facility; and housing, recreation and educational facilities for company personnel and their dependents.  The PASAR plant complex occupies 80 hectares in the 424-hectare Leyte Industrial Development Estate (LIDE). Completed in 1983 at the cost of US$300 million with the capacity to produce 138,000 metric tonnes of Grade A electrolytic copper cathodes annually, it was expanded in 1993 to its current production capacity of 172,500 metric tonnes per year.

In June 1999, a consortium of Philippine investors and Swiss trader, Glencore International AG, procured 90% of the Philippine Government's shareholding and its receivables from PASAR. This acquisition was carried out as part of the country's privatization program, thus, transforming the company into a privately-owned corporation.  Subsequently, the shares owned by the Japanese consortium were sold to a privately-held company.  Now, the capacity of the smelter has been expanded to 720,000 mtpy of concentrates in 2006, and the refinery will be expanded to 215,000 mtpy of cathodes by mid-2007.  The design of the plant was patterned after Japan's Tamano smelter and refinery plant, considered as one of the world's most efficiently-run smelters. The flash smelting process developed by Outokumpu Oy of Finland and modified by the Mitsui Mining and Smelting Company, was adopted for more flexibility in processing different grades of copper concentrate, high recovery of sulfur, and reduced power and oil consumption.  Copper concentrate, the basic feedstock undergoes a smelting and refining process in which impurities are removed and refined copper is extracted. Precious metals and other byproducts are also recovered in the process.  PASAR has expanded its smelter capacity to 720,000 mtpy of concentrates in early 2006. In May 2007, PASAR will complete a brownfield conversion from conventional starting sheet electrorefining to ISA process. Refinery capacity will be increased from 172,500 mtpy to 215,000 mtpy of coppr cathodes.

News January 11, 2018 - Operations at Glencore’s Pasar copper smelter have been suspended since last week due to a leakage in the sulfuric acid plant, Metal Bulletin has learned.  www.metalbulletin.com

August 27, 2017
- The Philippine Associated Smelting and Refining Corporation (Pasar) is due for a 15-day shutdown starting September 12, as it allegedly received several complaints regarding the foul odor emitting from its processing plant inside the Leyte Industrial Development Estate (Lide) in Isabel, Leyte. Lawyer Noli del Rosario, senior vice president for Legal and Corporate Affairs of Pasar, said the shutdown will give way to a “search and explore” activity to find any possible leaks in the plant’s system and equipment. Del Rosario said the Pasar’s anti-pollution protocols are “still in place and working," as he vowed to look into the complaints and address them. People living near the area have been complaining of the stench, believed to be sulfur dioxide discharge, coming from Pasar's plant, saying this poses environmental hazard to the populace. Also, about a hundred workers of its closest neighbor, the Philippine Phospate Fertilizer Corporation (Philpos), said that as per in-house monitoring, the ambient air surrounding Pasar's plant “has strong content of sulfur dioxide” and is apparently “beyond allowable level.” Philphos and affected Lide officials have filed a series of complaints before the regional Environment Management Bureau of the Department of Environment and Natural Resources (DENR), Department of Health, and local government of Isabel for a swift action on the problems caused by the harmful chemical coming from the plant. Asked for comment, Del Rosario said Pasar is committed to complying with all DENR standards and regulations on emissions, including those related to sulfur dioxide (SO2). “In the last month, some quarters have complained of SO2 emissions coming from Pasar alleging that these are of 'mild,' 'strong' or 'very strong' intensity. These complaints are couched in qualitative and subjective terms incapable of precise measurement,” Del Rosario said. He added: “Pasar has in place a Continuous Emissions Monitoring System or CEMS which records SO2 emissions in real time. With regard to the qualitative complaints raised, Pasar has not exceeded the TWA (Time Weighted Average) taken over any eight hour period.” The DENR, through the Clean Air Act of the Philippines, has set 0.07 ppm allowable level for sulfur dioxide discharge. But observers in the area said the initial ambient air readings at the area go as high as 6 ppm. Health experts said sulfur dioxide is a non-flammable colorless gas that is heavier than oxygen. It has strong and pungent odor that causes irritation to the eyes, conjunctivitis and corneal burns. Long exposure can cause irritation to the mucous membrane of the lungs and respiratory tract, bronchospasm, pulmonary edema, pneumonitis and acute airway obstruction. It can aggravate chronic pulmonary diseases such as asthma. Moderate to high exposure can cause skin irritation, nausea, vomiting, and abdominal pain. Those most at risk of developing problems, if they are exposed to sulfur dioxide, are people with asthma or similar conditions. Glencore, one of the world’s largest diversified commodities trader, owns 78 percent of Pasar. It acquired Pasar from the Philippine government in 1999. The Pasar incident contradicted the environmental policy of Glencore, which assures international and industry-specific environmental standards and requires their assets to undertake detailed risk assessment reviews and identify appropriate mitigation actions. “Our assets continually review their waste management procedures and identify opportunities for improvement, to minimize the impact of the waste we produce,” according to Glencore’s Waste Management Policy.  www.sunstar.com.ph

- Glencore Xstrata’s Pasar copper smelter in the Philippines plans to restart as soon as January 15, after being damaged by Typhoon Haiyan in November, two sources said on Wednesday.  The Pasar plant, majority owned by Glencore, is in Leyte province, southeast of Manila. It has been shut since around Nov. 7.  “Pasar have now told mine suppliers (to expect a) smelter restart Jan 15,” a trader in Europe said.  Another industry source confirmed plans to reopen from mid January.  Pasar produced 98,000 tonnes of copper in 2012. Analysts estimate the nine week shut down will lead to a loss of around 15,000-30,000 tonnes of refined copper. Pasar is expected to produce around 155,000 tonnes of refined copper in 2013.

- Commodities titan Glencore Xstrata PLC said Monday it has suffered heavy structural damage at Pasar, the Philippines' sole copper smelter, after supertyphoon Haiyan ravaged the central part of Philippines at the weekend."Initial assessments confirm that Pasar has sustained heavy structural damage to its operations," a company spokesman said in an e-mailed statement. "Preliminary estimates put a return to normal operations of at least four to six weeks," he added.Glencore Xstrata began to shut down the copper smelter on Thursday, a day before the supertyphoon, known locally as Yolanda, hit the country. The typhoon was the strongest storm to make landfall in the Philippines since 1991 and has resulted in an official death toll of 255 although the grim hunt for bodies is expected to result in substantially higher numbers. The Red Cross said it had ordered for 10,000 body bags."Our thoughts are with those employees and their families who have been impacted by Yolanda," said the Glencore Xstrata spokesman. "Pasar will offer all necessary support where we can," he added.Pasar is 78% owned by Glencore Xstrata, while the remaining 22% is owned by local investors. Copper production at Pasar fell 40% in 2012 due to a fire that halted production for about six months. Pasar has a copper cathode production capacity of 215,000 metric tons a year.

Outotec has been awarded a contract by Philippine Associated Smelting and Refining Company (PASAR) for the modernization of PASAR's copper smelter in the Philippines. The contract value exceeds EUR 12 million and it has been booked in Outotec's third quarter order intake. PASAR's copper smelter is based on Outotec® Flash Smelting technology. The original Outotec® Flash Smelting license dates all the way back to 1977. Over the years PASAR has regularly upgraded the smelter together with Outotec.Outotec's scope of modernization work this time includes equipment deliveries such as modern proprietary concentrate feeding system and burner, process advisor, furnace cooling system and anode casting shop including the supervision services. "PASAR and Outotec long-term relationship is a good example how the smelting technology can evolve by working together. By renovating and upgrading the older generation smelting plants with latest technology developments and our rebuild services, our customers can meet the increasing efficiency and environmental requirements and ensure their competitiveness far in the future", notes Robin Lindahl, head of Outotec's Metals, Energy & Water businesses.

February 1, 2012 - It took an unexpected snag in the operations of an important plant, to prod temporarily out-of -job workers to try other jobs.  Around 2,000 casuals and contractual workers were affected by the closure of the Philippine Associated Smelting and Refining Corp (PASAR) in Leyte. To help the displaced workers, the local government of Isabel had been conducting job fairs for skilled workers like pipe fitters and welders to help them find jobs outside the country.  An official of the local government unit (LGU) of Isabel, Leyte has expressed concern on the stoppage of operations of the Philippine Associated Smelting and Refining Corp. (PASAR) located inside the Leyte Industrial Development Authority in Isabel, Leyte.  It might be remembered that PASAR management temporarily shut-down its operations when its acid plant, where the electrostatic precipitator (EP) was located, burned down at around six o’clock in the morning of January 2. The EP is vital to the operations of the plant.  Allan Borinaga, senior administrative assistant to Isabel town Mayor Saturnino Medina expressed concern on the effect of the stoppage of operations saying that the town stands to lose in income as PASAR is the top source of income generation for the municipality.  Borinaga disclosed that with the stoppage PASAR management is seeking for a moratorium of sales tax payment. The LGU would suffer a big lose to as much as P 5 million every quarter from the non-payment of sales tax alone. He also said that the income received from PASAR is used by the LGU to defray the costs for its various programs and projects for the people.

January 9, 2012 - The Philippine Associated Smelting and Refining Corp. (Pasar), the only copper smelter and refinery in the country, has stopped its operations after a fire damaged its acid plant located within the Leyte Industrial Development Estate in Isabel, Leyte.  But Pasar management has assured its 800 regular employees and 1,500 service contractors will continue to report to work and will be paid although will be temporarily assigned to different tasks.  “We foresee a challenging time ahead due to the shutdown as we repair and rebuild the damaged portions of the acid plant. We are not yet sure how long this will take, but we are assessing what needs to be done in rebuilding the EP (electrostatic precipitator), to keep the shutdown as short as possible and to restart operating at full speed as soon as possible,” Pasar president Sias H. Els said.  Els added that Pasar is doing everything in exploring all the possible options and actions to recover immediately.  “Everyone will therefore continue reporting for work as usual until further notice, although perhaps with different work assignments, and everyone will get paid. We need to use the opportunity to do housekeeping and properly clean and do repairs where needed,” Els said.  Pasar’s acid plant, where the EP was located, was burned down in the morning of January 2. It took five hours for fire fighters to contain the fire.  The extent of the fire was severe but no fatalities and no direct injuries were reported. Minor burns were suffered by an employee, Orland Matuguina, who was involved in the fire fighting operations.  Fire probers initially estimated the damage at P15 million. But according to J. Paul Tan, Pasar’s assistant vice-president for industrial and community relations department, the damage could reach as $1 million.  “We could not immediately determine the actual damage. Our assessment continues. The acid plant alone costs a little over $1 million. But right now we are sending people to China and Japan to find for replacements of the burned machineries. We need it custom-built and that is why it will take us sometime to resume operations,” Tan said.   Tan admitted that Pasar’s operation is “not normal” and has affected the production of electrolytic copper cathode and refined copper anode where markets are very high in China, Korea, Taiwan, Vietnam, Thailand, Malaysia, Indonesia and Japan.  Tan said the company wants to restart operations by February.  “What happened was an integral risk of smelting. With the full support of our shareholders, we will overcome this challenge,” Tan said.  Tan added the company could continue operating but electronic precipitators is vital to its anti-pollution measures.
