Used plastic candle containers are piled up in a yard before they are decomposed at Plastkom's factory in Jesenice, Slovenia, November 6, 2017. Plastkom, a Slovenian candle-recycling company that is one of the few of its kind in Europe, decomposes about 1,400 tonnes of candles per year and exports most of the material to Germany. Company director Mojca Korbar says recycled materials include paraffin, metals and plastic. Plastkom, based in the city of Jesenice and employing 14 people, was established in 2010 and has since doubled its annual output of recycled candles. Staunchly Catholic Slovenians use about 6,400 tonnes of candles a year, mainly for placing on family graves, especially on All Saints Day on Nov. 1 and at Christmas and Easter. The Slovenian Court of Audit says Slovenia's government should do more to reduce the number of candles people use and educate them on the environmental impact of discarding melted wax.
