“…An increase of 13-41.5% after SS or SSCh application was detected for Ba, a nonessential and toxic element to plants and animals [41]. Plant removal of Ba from the soil was in the range of 12-20%, and our results agree with Norini et al [42] and Barbosa et al [43], who reported low Ba plant accumulation from the SS of biochar-amended soils.…”

Soil Remediation after Sewage Sludge or Sewage Sludge Char Application with Industrial Hemp and Its Potential for Bioenergy Production

Sewage sludge reuse in agriculture is increasing and is highly encouraged; however, it may pose environmental risk. Therefore, an integrated approach combining soil phytoremediation and further plant usage for bioenergy production is needed. In this study, we have examined the potential of industrial hemp (Canabis sativa L.) to remediate sewage sludge (SS) and sewage sludge char (SSCh)-amended soil (25–200 Mg ha−1) and improve soil quality. Additionally, hemp’s biomass and probable bioenergy yield was calculated for biomass and methane production. Heavy metal soil content increased with SS and SSCh dose, though hemp cultivation significantly reduced their soil concentrations. The heavy metals’ removal efficiency could be ranked Zn > Cu > Cr > Ni. There was an enrichment of micro- (Ca, Mg, Mn, S) and macro-nutrients (P) in SS and SSCh-amended soils. P and S removal by hemp was highly efficient, whereas other macronutrients did not show a substantial decrease in the soil. Only marginal removal was detected for Ba, Fe, Na, Ti and Al. The study showed that the optimal fertilization with SS or SSCh could be up to 25 Mg ha−1, when the highest efficiency of contaminant removal from the soil and the highest plant biomass production and bioenergy production were observed.

“…This effect was previously reported for mine soils (Madrid, Spain) enriched in the same elements, amended with sheep/horse manure, wood compost, Sphagnum peat and pine bark [40]. These opposite responses have been already documented by other studies [41][42][43], in which plants (Catharanthus roseus G. Don, B. napus, Alocasia macrorrhiza L. and Sedum alfredii (Hance) cultivated on pure SS showed enhanced growth compared to those grown on control soil, due to the abundance of organic matter, N, P and other micronutrients, such as Mn, Cu, and Zn. On the other hand, SS can also suppress plant growth due to its toxicity, as was reported by Suchkova et al [44], who did not record any natural plant species (i.e., Amaranthus albus L., Cynodon dactylon (L.) Pers., Portulaca oleracea L.) growing on 100% municipal sludge from Sindos (Greece), compared to sludges from other WWTPs.…”

Trace Metal Accumulation and Phytoremediation Potential of Four Crop Plants Cultivated on Pure Sewage Sludge

Phytoremediation is a viable strategy to remove trace metal contaminants from sewage sludge but still is poorly investigated. The aim of this study was to quantify the trace metal removal of B. napus, B. juncea, H. annuus, Z. mays grown on pure sewage sludge. Each species was grown on six different sewage sludge for 8 weeks and sludge were analysed for trace metal content and physico-chemical characteristics. Our results confirmed that all the tested sludge supported plant growth. The tested sludge showed a plant vigorousness lower (46% of sludge) or similar/increased (54% of sludge) compared to control treatment. B. juncea and B. napus were the most efficient species in the bioaccumulation, of trace metals. The average percentage of metals removed by the selected species was 0.2% for As, 0.85% for Cd, 0.09% for Cr, 0.36% for Cu, 0.36% for Ni, 4.2% for Se, 1.2% for Zn. In conclusion, our results showed that phytoremediation can be applied to sewage sludge, despite the chosen species have low efficiency in trace element removal. Further studies using hyperaccumulator species are needed which may lead to a higher efficiency of the process opening up new possibilities for the management strategies of this waste.

“…The combination of different biological strategies could lead to an improvement in the remediation performance as demonstrated for different micro-, vermi-and phyto-remediations applied in a sewage sludge polluted landfill 698 . Experiments placing earthworms, bacteria, and plants led to removal rates around 20-25% for heavy metals (Cd 15%-35%; Ni 24%-37%; Pb 15%-33%; Cr 7%-39%), roseus for which the translocation process was progressive in the treatment 699 .…”

“…Recent examples indicated the phytoremediation of As, Ba, Cd, Cu, Cr, Ni, Pb, Se, and Zn in sewage sludge-based substrates demonstrating the efficiency of Catharanthus roseus for which the translocation process was progressive in the treatment. 699 The microbial population present in activated sludge provides the chemical energy required by these processes. Thus, bioelectrochemical or microbial electrochemical systems are capable of converting chemical energy into electrical energy while employing microbes as catalysts.…”
