On World Clean Up day, September 15, 2018, Ecologists Without Borders in Slovenia organized a national voluntary clean-up activity, the third in the history of Slovenia. The Greenpeace team, which took part of the activity with volunteers and supporters, cleaned up at Rudnik in Ljubljana and collected about 2200 L of plastic waste and other waste. In addition a brand audit was also conducted, to find out which brands are most responsible for environmental pollution.
