Closed Loop gets flexible with new silos

Genesis Process Solutions has just completed the supply and installation of an internal storage system for Closed Loop Recycling in Dagenham.

Closed Loop Recycling takes waste soft drinks and water bottles made from PET along with HDPE milk bottles and recycles them back into food-grade plastic.

As part of a major expansion on site, Genesis Process Solutions was selected to supply three, flexible silos on load cells together with rotary valves. Other companies supplied cyclones, pipework and pneumatic conveying to fill the silos with Genesis ensuring a smooth connection between the silos and other filling equipment.

The silos will contain HDPE flake that has been granulated, washed, dried, float separated ready to be delivered to the extrusion lines. Phil Cameron at Genesis Process Solutions said: “We have been working with Closed Loop Recycling for quite a while as they had some of our silos on site and it made life easy in specifying the silo system as we knew what was required for this tricky material. We were entirely dependent on other suppliers delivering on time with ‘As Drawn’ equipment, which would ensure that everything fitted together.”

The new silos measure 2.1m x2.1m by 7.5m high and, because of the flow characteristics of HDPE flake, have been fitted with sweeping arm, flat bottom dischargers which eliminate the chances of ‘rat-holing’ or product bridging – a well-documented issue with flake material.

These three new silos brings the total number of flexible silos at Closed Loop Recycling to eight.

Genesis Process solutions will be exhibiting a Flexible silo, Brabender feeders and its own range of hopper flake dischargers at Interplas 2014.
