Daly Plastics selects Bollegraaf Recycling Solutions

The Appingedam, Netherlands-based company Bollegraaf Recycling Solutions has completed installation of a plastics sorting system at Daly Plastics, Zutphen, Netherlands. The capacity targets for the modular system were exceeded by more than 50%, according to Bollegraaf, separating 7 tonnes of plastics per hour. This enables Daly Plastics to realise its ultimate goal—production of regranulate for use as raw material in high-quality new products, the equipment supplier says.

“We chose Bollegraaf because their quality was higher than all other candidates and they possess the necessary expertise in the design, engineering, construction and supervision services required for the installation of an innovative system like this,” says Peter Daalder, director of Daly Plastics.

“Another important reason for selecting Bollegraaf’s systems is their robust yet flexible nature due to the modular structure. Recycling of waste is a process that is continually changing. If the range of materials for recycling changes, then the system can be easily modified and restructured without incurring high costs,” he says. “In addition, they are a reliable partner who provide all of the knowledge and services required to optimise processes and get the most out of the systems.

Frits Eding, project manager at Bollegraaf Recycling Solutions, says, “Daly Plastics’ goal was to process 4 tonnes per hour, yet they are currently achieving between six and seven.”

The first part of the system is a coarse shredder, followed by the removal of iron contamination. The resulting output is then processed through ballistic separators—Ellipticals by Lubo Systems B.V. (a member of the Bollegraaf Group)—to remove small contaminants, such as sand. By means of optical scanning, the material is then separated into different types and, if desired, different colours. A manual check can then be carried out if necessary. The output goes through a baler to be processed into homogenous bales. This material is then further reprocessed using a DRD dry-cleaning system and granulation. Daly Plastics now has all of this technology at its disposal.

The Lubo Elliptical is used to separate 2D materials from 3D materials. The adjustable grilles on the paddles ensure the desired separation size, according to Bollegraaf. They also feature up to 2,500 milimetres of functional width, air support to optimally aid the screening process.

The facility also features the Mistral Film machine from Pellenc ST, which uses near-infrared and vision technology.
