Got an interesting email through the other day telling me all about biodegradable foam board. They state

Paper Spectrum Biodegradable Foamboard

Our white 5mm foamboard now has a 15% recycled and biodegradeable centre formulated with bio resins which will degrade in the bacteria rich environment of landfill sites in 1 – 5 years, compared with 80 – 450 years with conventional foam boards. In all other respects it will perform equal to, or better than, conventional foam board.

I have had a quick look and it looks very impressive, so next time I need foamboard I know where I shall be going.

Also whilst I am not advocating this particular supplier, the product looks good and it also demonstrates the email marketing can work …
