Assessment of soil quality in the area of casting parts waste storage specific to cast iron activities


Keywords: cast iron, sand waste, soil, assessment

The purpose of this paper was to present an environmental assessment specific to a case study with reference to the storage of sand waste from a cast iron foundry, a factory with a long period of operation located in Transylvania, Romania. The environmental assessment started from the need to achieve compliant conditions for long-term storage of waste specific to cast iron casting parts activities. The activities performed in the project were carried out in stages and in parallel with the activities of sand waste valorification from the non-compliant deposit. The collaboration of the factory owner with the local environmental authorities was able to effectively materialize the objectives of the soil evaluation and facilitated the obtaining conditions for new compliant deposit construction. The evaluation of the soil quality was performed in areas where the deposited material, respectively the sand waste from the casting of the cast iron was already valorificated and, in that case, the access to the soil layer was facilitated. Thirty soil samples and a control sample were analyzed and interpretation of the results was performed in corelation to specific legislation. The conclusions of the study were provided to the beneficiary and, also to the environmental authorities in order to authorize future activities (capitalization of the remaining waste, arrangement of a new landfill).
