These are not actually trees but more of making it look like them. The Frozen Trees were something that were meant for the Christmas Season but the real twist here is that they are made from IKEA Plastic Bag Dispensers.
The Frozen Trees were actually designed for the D. Pedro IV square in Lisbon, Portugal, offering a sensuous touch to the public area. Credit goes to LIKE Architects for coming up with this neat design. The said Frozen Trees were made of recyclable polypropylene plastic which in turn produced 30 ethereal, LED-illuminating street lights, something cool to see and conservative as far as energy consumption needs are concerned.
