Pulp egg trays become valuable biofuel

A briquetting press and shredder has helped Cheshire-based pasteurised egg producer D Wise turn a waste stream into a valuable biofuel.

With a large number of waste egg trays produced daily, a commercially viable and environmentally friendly disposal alternative to landfill was essential. Egg trays are now converted into high-density fuel briquettes without the need for additives, thanks to Weima equipment supplied by UK distributor Fercell Engineering. Paper briquettes deliver a similar calorific value to that of brown coal.

The turnkey solution included a Weima WL4a single shaft shredder with high-volume hopper, 18.5kW three-phase belt drive and a patented 252mm diameter by 600mm 'V' rotor. The enhanced volume of cutters improves the efficiency of the standard WL4 and, with programmable logic control, many machine safety features are possible along with ram load limit switch protection.

Inter-connection between the shredder and briquetter is via a worm screw out-feed conveyors.
