bottles with deposit, but due to the deregulation of the Systembolaget's suppliers, the former sole supplier V&S Group dropped the deposit on their bottles due to the restricted bottle shapes giving V&S a disadvantage compared to the competitors. The bottles could be returned and deposit refunded until early 1999 at Systembolaget. The legislation regarding container deposit systems was updated so that from 1 January 2006, containers from other plastics and metals, e.g., steel cans, can be included in the deposit systems. The law also makes it illegal in Sweden to sell consumption-ready beverages in containers that are not part of an authorized Swedish container deposit system, with the exception of beverages that mainly consist of dairy products or vegetable, fruit, or berry juice. However, private importation from (mainly Eastern European) countries without deposit occurs by vendors that thus compete with a somewhat lower customer price. The recycling of these contraband cans has not been seen as a problem, but Returpack made a campaign in 2010 offering 0.10 krona for each imported can (without deposit) to the benefit of WWF, retrieving 17 million cans. In 2011, a similar campaign was repeated, retrieving almost 18 million cans. The 1.5 L refillable PET bottle with a deposit of 4.00 kr has been discontinued, and has been replaced by the 1.5 L recycle PET bottle. The last day for returning bottles made by Spendrups for deposit was 30 June 2007, and the last day for bottles made by Coca-Cola Sweden was 30 June 2008. Although Sweden is one of the leading countries in recycling of beverage containers, Returpack uses TV commercials to promote more recycling. Commercials have been made with well-known melodies sung, like "Guantanamera" and "Pata pata"—sounding like Returpack's slogan "panta mera" (i.e., "recycle more"). In 2016, the overall recycling rate was 84.9% for both aluminium cans and PET bottles, which translates to 177 packages per person in Sweden. Switzerland and Liechtenstein In Switzerland, there is a government ruling that 75% of containers must be returned, otherwise a deposit system may be introduced. Currently a handful of beverages, including milk, sold in glass bottles are done so with a small deposit of 30 or 50 rappen paid by the purchaser, which is returned when the empty bottle is brought back to the store. According to the Swiss Federal Office for the Environment, The IGORA-Genossenschaft aluminium recycling cooperative levies a prepaid disposal fee on
