LDPE film recycling: Foam Industrial doubles its recycling capacity to about 14 thousand tons per year

Introducing the shredder-extruder combination

The Central American company from El Salvador, Foam Industrial, produces disposable plastic bags and food packaging. Founder and CEO Axel Rivera's demands on production were high from the very beginning: In the spirit of the circular economy, he wanted to recycle plastic waste and integrate it into his production process. As a result, recycling has been part of the story at the production site since the company’s inception in 1998.

To start with, Axel Rivera built the machines for LDPE film recycling himself. Later he purchased low-cost equipment from Taiwan. But he did not find any of these solutions satisfactory. It was only PURE LOOP recycling technology that met all his requirements. "More flexibility, more throughput, lower power consumption, and more efficiency. PURE LOOP delivers it all. I was - and still am - highly satisfied!" he says about the plant, which started production in 2015.

Second recycling plant already purchased

In 2020, based on the high level of satisfaction and high profitability, Foam Industrial decided to invest in another ISEC evo recycling plant. "We want to use the latest innovation and technology of PURE LOOP for the development of the country and my company," says Axel Rivera, "After the successes with the first plant, we decided to expand our business. It was an easy decision to make."

Following the purchase of the second plastic recycling machine, the company doubled its capacity in LDPE film recycling. As a result, they increased the throughput from 7 to around 14 thousand tons of plastic per year.

"We have a very good business relationship with PURE LOOP and we are sure that we will buy more machines," says Axel Rivera about the way the two companies continue to work together.

This is due to the special way in which the materials are fed into the extruder.

Prior to extrusion, the plastics are pre-shredded by the single-shaft shredder. They are then fed into the extruder by the conical feed system, without the need for additional propulsion by compressed air, for example. Meanwhile, the active rotor and stationary knife cooling system ensures that the materials are subjected to the lowest possible thermal stress.

The patented double feed ram system is responsible for keeping the extruder filled up. Because the plastic materials are processed at such a low temperature, it is possible to feed the plant semi-continuously.
