One week's worth of plastic waste, used and collected by the Downie family, is displayed in Pitlochry, Scotland, Britain, May 28, 2018. "We recycle what we can, and try to minimise waste generally, including food which is composted," said Karen. "Even the plastic that is recycled will ultimately have an impact. Discarded plastic does not decompose and presents a serious and irreversible long-term threat to the health of our planet, and more immediately to animals which should enjoy pristine habitats," she added. "Alternatives do already exist in many cases, but it seems are simply not widely offered because plastic offers cheap convenience. Manufacturers, retailers and governments need to do more to drive the necessary decline in use of plastic." REUTERS/Russell Cheyne

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.
