Biffa Polymers has equipped its food grade high-density polyethylene (HDPE) bottle recycling plant with a new swan neck conveyor solution.

Manufactured by recycling engineering specialists Middleton Engineering, the conveyor is designed to feed material at up to 2t per hour or 50t per day.

Materials are transported through an electronic sorting unit that removes non-compliant material and lets the clean HDPE waste stream pass into the granulator.

The HDPE is then heated, extruded and cut into pellets. It is sold in the market to make new dairy bottles and other commodities.

"The plant is up and running following an earlier major refit and we continue to lead the market in closing the loop on post-consumer plastics recycling."

The conveyor operates as part of Biffa Polymers' milk bottle processing line for post-consumer plastics. This was designed after carefully determining the optimal design by considering the size of vertical rubber flights to ensure efficient delivery of material even at higher speeds.

Middleton designed the conveyor to minimise spillage issues and overcome overloading and jamming at the foot of the conveyor.

Biffa Polymers Engineering and Maintenance manager Martin Brass said: "We visited a number of Middleton customer sites before selecting the company to design and install the new conveyor.

"It's running well and the team reacted very promptly to initial issues with the rubber belt untracking, making permanent design modifications following our input.
