Waste streams - 2 shot molded PC rejects

Hello again

Not really a standards or requirements post but really struggling to find a reliable waste stream to collect NOK plastic parts for regrind / recycle . They are panels for a lawnmower and are 2 shot PCs with a foil feature . Possibly a garden furniture manufacturer or something similar could use to granulate the parts are approx 15cm by 15cm . We also produce weekly 4 octi bins , so large quantity . Could anyone point me in the right direction to try and keep away from incineration and land fill .
