Environmental Sustainability Assessment of Soil Amendments for Enhanced Phytoremediation
Publication: Urbanization Challenges in Emerging Economies: Energy and Water Infrastructure; Transportation Infrastructure; and Planning and Financing
ABSTRACT
Phytoremediation is a feasible and promising technique to treat mixed contamination in soils because of its good field-scale applicability. However, survival of the plants in highly contaminated areas is one of the most important limiting factors. The addition of organic matter to the soil buffers the negative impact of heavy metals and promotes biodegradation of organic contaminants thereby increasing the chances of survival of the plant species. In this study, an environmental impact assessment of the use of four different organic amendments namely biosolids, biochar, compost, and animal manure applied to a field-scale phytoremediation for treatment of mixed contaminated soil is performed. The environmental impacts associated with the production of each of the soil amendments alone are assessed. Thereafter, the total environmental impacts from the material production and transportation of the materials to the field site are evaluated. The results from the environmental sustainability assessment show that the use of biosolids as organic soil amendment is the most sustainable option.
