Resource activation method by sorting buried wastes

Technology / Service Summary

This technology can effectively utilize resources by sorting wastes which are dumped illegally or generated by the disaster of a huge earthquake or heavy rain into soils and wastes by type and recycling.


Utilizing resources by sorting illegally damped waste or disaster wastes into soils and wastes by type


a) Determine the sort flow and equipment to be used according to the mixing ratio of soil and waste, the type of waste to be sorted, the required low
b) Available to improve sorting accuracy by mixing an appropriate amount of quicklime or polymer-based modifier, in case of high hydroscopic wastes
c) Available to support from small-scale systems to large-scale that can sort and treat wastes of 500 m3 or more per day


a) Excellent long-term stability of effect after treating the contaminated soil
b) Soil strength does not become excessive after treating
