Recycling Solution

PURE LOOP solution delivers impressive recycling of challenging production waste - Kilometres of quality: the best recycled pellets for irrigation pipes


The shredder-extruder combination from recycling technology provider PURE LOOP is the ideal solution for recycling challenging production waste. This category includes drip tapes and irrigation pipes that accumulate as waste during the production of irrigation systems or are rejected during quality inspection. Manufacturers who already implement this technology reuse production waste in the form of recycled pellets in proportions of up to 20 percent - without any loss of quality compared to production from virgin material.

"This level of reuse can still be significantly increased thanks to the high quality of the recycled pellets," says Manfred Dobersberger, Managing Director of PURE LOOP. "The high demands on the recycling process result from the high volume of the bulky input material as well as the material composition of the drip tapes and irrigation pipes," he explains. Their job is to ensure that crops can grow and thrive, using as little water, fertiliser and pesticides as possible. For this purpose, either thin-walled HDPE drip tapes laid on the surface or HDPE irrigation pipes buried in the ground are used. The water is distributed through emitters. In the case of the thin-walled drip tapes (150 - 250 µm), these are LLDPE injection-moulded parts which are spaced at regular intervals of around 20 cm. In the case of thick-walled irrigation tubes (over 300 µm), the emitters are also fitted with a silicone membrane for pressure compensation, so that the same flow rate of water is discharged from each emitter over the entire length of the tube and the flow of water is not obstructed by soil, sand or roots growing into the emitter.
