Peretz noted that Israel and Bulgaria face many similar environmental challenges. He stressed the importance of the Maintenance of Cleanliness Fund, river and stream rehabilitation, and enforcement of the "polluter pays" principle in dealing with some of those challenges. "Unequivocal enforcement [of polluter pays] gives polluters the necessary motivation to use technologies that are more advanced and less polluting," said Peretz.
Mihaylova was in Israel to attend Watec Israel 2013 – the international conference and exhibition on water technology and environment control held annually in Israel. She also was here to encourage environmental cooperation between Bulgaria and Israel and to learn from Israel’s experience in management of water resource and waste. To that end, MoEP professionals presented to the minister and her staff the principles behind their activities.
Israel and Bulgaria signed a Declaration of Intent on Cooperation in the Field of Environmental Protection in 2011. While here, Mihaylova also invited Peretz to visit Bulgaria, and asked for his support in the promotion to Israeli entrepreneurs of a Bulgarian water conference, to take place in March 2014.
