About this project:<\/span><\/h3>\n[\/vc_column_text][vc_column_text css=”” text_direction=”default”]Sodecon investigated whether microbial degradation<\/strong> of contaminants can be accelerated by targeted soil heating. The technique was tested in the laboratory at two sites: one with petroleum hydrocarbons in soil, and one with butanol and methyl ethyl ketone in both soil and groundwater. <\/p>\n

Innovative approach<\/strong>
\nBy raising the temperature to 25-30 \u00b0C, a strong stimulation of methanogenic degradation processes<\/strong> was observed. The major advantage of this technique is that only heat needs to be applied – no chemicals or above-ground treatment plants are needed. In addition, heat disperses relatively homogeneously in the subsurface, ensuring efficient stimulation even in less permeable zones.[\/vc_column_text][vc_column_text css=”” text_direction=”default”]Results<\/strong><\/p>\n

    \n
  • Petroleum hydrocarbons degradation was accelerated up to 3 times<\/li>\n
  • An acceleration by a factor of 2 to 5 was observed for butanol and methyl ethyl ketone<\/li>\n
  • Biogas production was measured to quantify degradation rate<\/li>\n<\/ul>\n

    The technique is particularly suitable for hard-to-reach organic contaminants<\/strong>. In addition, the use of solar panels<\/strong> offers a sustainable way to heat the soil locally. <\/p>\n

    This innovative approach offers new prospects for the remediation of contaminated sites without heavy infrastructure or complex injection techniques.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
