REUSED BOTTLE CHRISTMAS TREE, SPAIN
Wednesday 04 Apr 2012
Simple, austere, contemporary, reusable and low energy consumption were the premises for the Christmas tree promoted by the "Mancomunidad de la Comarca de Pamplona".
Pamplona's Common Region is an entity which manages urban waste collection and recycling thereof, among other competences, for 355.000 inhabitants.
Due to Christmas celebrations and with the aim of sensitizing the citizens about recycling, a tree with reused and reusable glass bottles was projected and installed. The structure of the tree consists of a cone-shape steel structure. This cone has four quadrants, screwed to each other. This fact allows a comfortable assembly and dismantling of the structure, as well as its transportation and storage. This means that the reusability of the structure and of the bottles is guaranteed throughout the years.
A 3.300 kg counterweight has been projected to support wind's push and suction which can also be dismantled.
The tree is 6m high and has 4,80m diameter on the base.
It has been located in "Baluarte's Auditorium" Square during 2011-2012 Christmas time.
The number of the bottles used is of 2.328. The 90% of them are green glass, and the 10% transparent glass.
The illumination has been carried out by Waterproof luminaire (IP65) for linear fluorescent lamps. PHILIPS TCW060, with TL-D lamps and HF ballast, 2 versions: 2x18W (16 pcs) and 2x36W (24 pcs), colour temperature 840, total installed power of 2.3 kW (2.304W).
The lights are arranged radically into three circular rings in parallel planes to the base. The light is projected towards the cone's vertex illuminating the bottles.
An explanatory panel was located next to the tree with a message about the responsible attitude of the citizens in terms of recycling. The 2.328 bottles involved the glass recovery of 13 families of Pamplona's region along a year.
