Life+ RusaLCA project Ana Mladenovič, 3.10.2016
Nanoremediation of water from small waste water treatment plants and reuse of water and solid remains for local needs Partners: Program LIFE+ - ZAG (coordinator) Duration of the - Jožef Stefan Institute project: 2013 - 2016 - PKG Šprinzer Mirko - Structum - NLZOH, Novo mesto - Municipality of Šentrupert - Esplanada
Kick off meeting, Ljubljana, 2013
What was the motivation behind the proposal?
Water is everywhere - 71 % sufrace of the planet is covered with water - the most common substance on earth.
Water is a finite source
Water is the main costituent of living organisms: 70 - 85 wt. % of human weight – the most important nutrition
Tree: 75 wt. % of water
Earth salt water (97 %) : fresh water (3 %)
Some facts about fresh water 70 % of this fresh water is actually frozen in the icecaps of Antarctica and Greenland. Of all the water on the earth, humans can used only about 0.3 % of this water. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.
If all the world's water were fit into a gallon jug, the fresh water available for us to use would equal only about one tablespoon. 4.5 litres
Climate changes 1880 - 2012 Average temperature of oceans and land has increased for 0,85 ° C.

T he world’s ever growing population is putting more and more strain on the fresh water supply.
Water consumption
Urban water crisis - water is the oil of 21. century • Finite sources of fresh water • Growing population • Climate changes
In Slovenia we have an exceptional abundance of water But- how long will it last? Privatization of water sources: 17 out of 29 boreholes belonging to our food production industry have passed into the hands of foreign owners. The level of grounwater in Slovenia has been geting lower since 1984, and the quality of water has also been reduced.
Climate changes – drought Jezersko - Planšarsko jezero, April 2012
Sustainable water treatment • reduction in the needs for water, • use of renewable sources of water, • efficient use of water.
Aim of the RusaLCA project 1. To reduce the consumption of water obtained from natural sources by up to 30 % - using remediated water from small biological wastewater treatment plant in Šentrupert 2. To establish of a protocol about the use of solid waste obtained from that plant, and from nano- remediation tanks, in different types of composites for use in the construction industry. 3. To disseminate of knowledge and good practice among the technical and lay public.
