LEWISTON — Compounding Solutions announced Tuesday that it’s doubling the size of its Goddard Road building to 120,000 square feet, growing the business and the number of employees.

The company makes high-quality plastic pellets that are melted and then either extruded or molded to become everything from medical catheters to L.L.Bean boot bottoms.

“We expect to grow to 100 people over the next two years, which would be an additional 25 to 30 jobs from where we are currently,” spokesman Nick Norton said.

The construction, which will start this spring, will enable the company to create eight additional compounding lines. It currently has 13. The expansion also allows for more warehouse space.

Norton said 80 percent of Compounding Solutions’ business is with medical device manufacturers. Much of the rest is with companies that make sporting and household goods.

“We have a bunch of customers all over the U.S. and then we’re growing in China, in Europe — the rest of Asia actually — and getting into Central America and some South America,” he said. “China is the biggest growth area.”

Compounding Solutions originally built its facility at 258 Goddard Road in 1999, the same year the company was founded by Scott Neal. It has expanded several times since.

The company runs two 12-hour shifts several days a week with much of the work done in a certified clean room.

“It’s all environmentally controlled; you have to gown up when you go in there, wear hairnets,” Norton said. “It just keeps everything completely clean so you don’t get contamination in the pellets. The sensitively of the products, you don’t want something to get in there and cause a problem during a surgery.”
