The suppler I use was happy to collect small amounts when I had a delivery but things changed and 'management' stopped them doing it! I now pay for a 'not to landfill' waste collection each month!.
You could try Perspex - they do have a set up that collects and recycles but they were more interested in having a contract rather than a one off!
