Disposing of current paint cans

According to Deluxe website

Can I recycle empty paint cans?

Yes.

Empty paint containers can be recycled, both plastic and metal, where facilities exist.

Local Authorities will be able to tell you how and where this can be done – many have Household Waste Recycling Centres or Civic Amenity Sites where paint containers can be disposed of responsibly.

Can I recycle the Dulux colour guide?

When you've finished with the colour guide you can recycle it in the same way you would any magazine or paper.

This piece of information particularly caught my interest 

You may be surprised to notice that the Dulux colour guide is not printed on recycled material - this is due to reasons of colour accuracy. However we do work closely with our printers to ensure waste is minimised and that the paper used is PEFC certified. This means that the wood used for the paper comes from forests that employ world recognised, sustainable management programmes but wherever we can, we specify the use of recycled paper and cardboard in our business.
