Scientists of Perm Polytechnic University (PNIPU) developed a method to convert toxic sulfuric and base waste from oil production to a harmless road soil suitable for a hard Russian climate. This was reported to the “Gazeta.ru” in the press service of the scientific institution.
Sulfuristic and base wastes produced during oil purification have high toxicity and disposal requires significant costs. Researchers proposed a way to process a cellular silicate material that did not harm the environment.
To test the polytechnics, a sample was formed by mixing sulfur-base wastes with an amorphous trepel (sedimentary rock) and subjecting the heat treatment mixture at a temperature of 700 ° C. The samples then spent freezing cycles (-20 ° C) and dissolution (6 ° C) to assess their resistance to winter conditions.
“After the first cycle of ice cream clutch, the specific clutch of the soil decreased to half and 15%with the tenth loop. During the compression, the deformation module doubled, but from the third one to the tenth cycle, 70%grew. At the same time, the density of the technogenic soil is 30% lower than the natural, which reduces the load at the base. ”
The use of technogenic soil not only solves the disposal of toxic wastes, but also allows you to save natural resources.
