Negative Effects

Cement kiln co-processing technology is one of powerful method for disposal soild hazardous waste internationally owing to advantages of economic and environmental friend. However, It seems to be abused in brownfield remediation in Chongqing recently, for instance, it is ubiquitously recommeded or pratically applied for disposal chromium conteminated soil. To help local environmental protection departments clarify the advantages and limitations of cement kiln for Cr-contaminated soil treatment, this paper focuses on advantages and the negative effects of co-polluters in Cr-contaminated soil.

The Cost

It is shown that the mechanical remediation of oil-contaminated soil is carried out quickly and radically, and the cost of this method (from 3.8 to 62.4 million rubles/ha) is several times higher than the cost of bioremediation. Soil cleaning by in situ bioremediation can last from 1 to 3 growing seasons, but it does not require the transportation and disposal of hazardous waste and does not destroy the soil cover. Adding sorbents and ameliorants for bioremediation of oil-contaminated soils is often justified, since it significantly expands the capabilities of the method, although it increases the cost of cleaning from 1.0–4.3 to 1.1–18.3 million rubles/ha, depending on the type and dose sorbent.

Stable Glass

Various types of contaminated soil and hazardous waste that have a negative impact on the environment and human health can be treated with the vitrification process. This process is based on thermal treatment of contaminated soil or waste at high temperatures, with the addition of additives, whereby the soil/waste melts and a stable glass is formed. The resulting glass and glass-ceramic products have good mechanical resistance, chemically are resistant and immobilize contaminants, thus preventing their further negative impact on the environment. This paper presents a literature review of the vitrification process of different types of contaminated soil and hazardous waste.

Effective Assessment

Effective assessment and remediation of hazardous waste sites dictates that analytical methodologies be developed which assist in the evaluation of site contamination and simultaneously make efficient use of sampling time and resources (1). Optimally, a technique would provide on-site personnel with immediate and accurate information concerning the identity and concentration of inorganic soil contaminants (2).

scholarly journals Remediation and treatment of dioxin contamination: a former sawmill site with soil and sediments contaminated with dioxin and pentachlorophenol have been remediated using excavation methods, and the most dioxine impacted soil have been successfully treate

Excavation Methods

Between 1928 and 1976, a sawmill was located at the shore of Brosjön in the small village of Ydrefors in Ydre municipality in eastern Sweden. During the last ten years of the sawmill’s operating years, a product namned Servarex was used to prevent fungus attacks of the timber. Servarex caused a contamination of dioxins in the soil, as well as pentachlorophenol (PCP) in groundwater. In the main study, the sampling revealed concentrations of dioxins (610,000 ng/kg) that was the highest detected level in Sweden. During the autumn of 2013, RGS 90 performed remediation of dioxins contaminated soil and sediment through excavation. The dioxins contaminated soil with levels above the hazardous waste limit (15,000 ng/kg) is not allowed to be deposed in Sweden. The soil was therefore successfully treated with chemical oxidation at RGS 90:s facility in Norrköping, Sweden.
