The Christmas decorations have #e down and the Santa costume has been put away for another year. But what to do with that tired-looking Christmas tree?
   
    Well there is a new option for the carbon-conscious... why not eat your tree?!
   
    A chef in Copenhagen has decided that the best way to give an old tree a new lease of life is to put it on a plate.
   
    Rene Redzepi's gastronomic experiment has proven so popular that customers are flying round the world to eat at his ?150-a-head (1,500 yuan) restaurant.
   
    BBC reporter Stephen Sackur said that "the needles from your average Christmas fir can be delicious" and was impressed by Redzepi's green credentials. The chef's raw materials are sourced locally. He avoids adding to his business's carbon footprint by buying products foraged from the sea, the shore or the forest. And ingredients that have to be farmed are supplied by organic producers.
   
   
    Eating your tree is one way to stop all that Christmas cheer going to landfill.
   
    But other eco-friendly options are open to the less adventurous. Leftover food makes for some simple but wonderful suppers. This year's Christmas cards can be recycled as decorations next year. And that reindeer jumper you received as a gift from Auntie Mary might just be next year's present for Cousin Ben - some call it "re-gifting".
   
    As the old saying goes: one man's junk is another man's treasure.
