or marbles. Light sculptures are also made in everything from wire-mesh frogs to artificial palm trees outlined in rope lights. In Pakistan, fairy lights are often used to decorate in celebration of Eid ul-Fitr at Chaand Raat, which occurs at the end of Ramadan. In India on Diwali too, homes, shops and streets are decorated with strings of fairy lights. Environment, recycling, and safety Christmas lighting leads to some recycling issues. Annually more than 20 million pounds of discarded holiday lights are shipped to Shijiao, China (near Guangzhou), which has been referred to as "the world capital for recycling Christmas lights". The region began importing discarded lights circa 1990 in part because of its cheap labor and low environmental standards. As late as 2009, many factories burned the lights to melt the plastic and retrieve the copper wire, releasing toxic fumes into the environment. A safer technique was developed that involved chopping the lights into a fine sand-like consistency, mixing it with water and vibrating the slurry on a table causing the different elements to separate out, similar to the process of panning for gold. Everything is recycled: copper, brass, plastic and glass. More cities in the US are establishing schemes to recycle Christmas lights, with towns organizing drop-off points for handing in old lights. As of December 2019, most scrap metal recycling centers will purchase traditional incandescent Christmas lights for between US$0.10/Lb - USD$0.20/Lb (€0.20/Kg - €0.40/kg). This scrap value is primarily derived from the recycling value of the copper found inside the wire, and to a lesser degree, other metals and alloys. As an example, a standard strand of modern incandescent Christmas lights weighing about 0.72 Lbs (0.33 kilo) was found to have less than 20% recoverable copper by weight. Installing holiday lighting may be a safety hazard when incorrectly connecting several strands of lights, repeatedly using the same extension cords for the lights to plug into or using an unsafe ladder during the installation process. Light sculptures Christmas light sculptures, also called motifs, are used as Christmas decorations and for other holidays. Originally, these were large wireframe metalwork pieces made for public displays, such as for a municipal government to place on utility poles, and shopping centers to place on lampposts. Since the 1990s, these are also made in small plastic home versions that can be hung in a window, or on a door or wall. Framed
