The Nižná Slaná landfill is located on the northeastern side of the village of Nižná Slaná in the hills directly above Etelka Huta, one of the most unique technical monuments in the Gemer region or perhaps in the entire country, representing the long and rich history of mining in that region. The landfill contains waste from ore processing in the region and, according to estimates, reached a volume of almost 5.5 million. m3. the retention wall itself is about 95 meters high. In the past, several experiments were conducted to determine whether it was possible to cover the area with vegetation. Our associates asked the mayor if they could test our humic acid formula on site to see if there would be any reaction. A month later, some very noticeable changes were observed.
Area: around 21 Ha (12.5 Ha – tailings pond)
Environmental burden: open unsecured landfill with a high concentration of toxins (As, Cd, Pb, Hg, etc..)
Goal: prevent the mobility of harmful dust by covering the entire site with vegetation
application of HUMAC® Agro with grass seeds on an area of approximately 16 m2 as a first test (August 7, 2020)
after one month (September 7), the area was covered with grass where HUMAC® Agro was applied
a large part of the test area was unfortunately damaged by motorcycle riders.
