    I worked out a while ago it was cheaper to buy a good quality used plastic welder to fix my bumpers than it was to pay someone to do it .......... This leads you onto an exploration of plastic welding (obviously). The welder can only weld certain plastics, some must be glued with specific glues etc..

    First you need to work out what type of plastic it is. Once you have, you need to use a "glue system" or a plastic welder with the correct base material as a welding rod to join it.

    Identify Plastics

    Have a read here, there is another really good site I found and printed out a while back on identifiying and welding/joining plastics. You local plastic shop will sell the varieties of welding rods that you need.

    Glueing Plastic

    Mocky,

    AFAIK the white chopping board plastic is a nylon material. As far as a potential adhesive for nylon material goes a quick internet search pointed me towards "Locktite Epoxy Plastic Bonder" with suitability advice as follows:-
    Recommended For

    Bonding substrates such as: PVC, polycarbonate, acrylic, ABS, FRP, Nylon™, Mylar™, Delrin, phenolic, aluminum and stainless steel

    Not Recommended For

    • Applying at temperatures below 40°F (5°C) or above 70°F (21°C)
    • Bonding polyethylene, polypropylene, Teflon™ or other non-stick surfaces
    • Use in continuously wet areas, prolonged immersion in water or use in potable water systems
    There are others as well, but they seem less common and more specialised. Loctite products I would think would be relatively easy to source. Not sure what you're doing, but might be worth trying on a sample.

    Cheers

    Dave

    Mocky, how's it going mate, I had to glue some plastic a while back and to find out what sort of plastic and what glue was suitable it required that you cut a thin sliver (shaving) of the plastic and set it alight. Depending on the smoke colour and how it reacted, this would point to the type of glue needed, unfortunately I cannot find the literature on it. I would advise reading "Identify Plastics" posted by DoubleChevron, good luck, Regards Frank.
