SHANGHAI — Shanghai Intco Industries Co. Ltd. was established 20 years ago in the United States as a trading company, but now based in China, the firm claims to be one of the world's largest recyclers of polystyrene waste.
Every month almost 5,000 tons of expanded and extruded PS comes to Intco's three facilities, in Shanghai, Shandong and Anhui.
The end result? Picture frames.
Founder Frank Liu began his scrap recycling and manufacturing business when he returned to China. The technology was developed in the United Kingdom using virgin PS, and a South Korean company invented the process of using recycled PS instead. Intco claims to be the first company in China to use the technology.
For Intco, the process starts in countries around the world where PS is collected and compacted into blocks. Intco pays up to 40 cents per pound for the best quality material (depending on quality and location), which it ships to China and extrudes it into long profiles.
The finished product is sold under the brand name Greenwood.
When the company opened its first factory in Shanghai in 2001, more than 90 percent of its products ended up in Wal-Mart Stores Inc., Michaels Stores Inc. and Target Corp. stores in the U.S. But as other global markets are growing, the U.S. now accounts for 60 percent of its sales, with Europe right behind.
Mia He, sales administration supervisor for Greenwood Products, says sales have been growing 20 to 30 percent per year for more than five years. Each month, Intco loads up 400 40-foot long shipping containers worth of products to be sent to global markets, netting the company 2013 sales of $150 million.
The company is expanding its end product market and beginning to manufacture garden barriers and furniture, but they are faced with one big problem, says Lucy Shen, Intco's EPS recycling global manager: scrap PS is hard to come by.
The company is buying as much scrap as it can, but it's still not enough to feed the growing company. Currently its biggest source supply is from Japan, which sends 2,000 tons a month. Europe sends another 1,000 tons. The U.S. sends only 500 to 600 tons per month, Shen said.
“Now everything is limited by the amount of raw material,” Shen said.
