“…Results obtained in the literature regarding the bioleaching of metals from soils, obtained under similar experimental conditions (use of Thiobacillus microorganisms, sample agitation (120–170 rpm), extraction time (5–48 days) and temperature (28–30 °C)) have shown that good extraction yields can be obtained for: Cu: 44% [ 39 ], 46% [ 40 ], 20–73% [ 41 ], 72. 8% [ 42 ], 69–92% [ 43 ], 95% [ 44 , 45 ], 51–72% [ 46 ], 78% [ 47 ], 80.6% [ 33 , 34 , 35 ], 82% [ 31 ], 83% [ 48 ], 89–96% [ 49 ], 95–96% [ 50 ]; Pb: 10–54% [ 43 ], 16–60% [ 50 ], 18% [ 40 ], 33–72% [ 51 ], 39.4% [ 42 ], 75–84% [ 49 ]; Ni: 10–47% [ 50 ], 35–65% [ 51 ], 69–92% [ 43 ], 75–93% [ 49 ], 78% [ 40 ], 90% [ 33 , 34 , 35 ]; and Cr: 14% [ 40 ], 10–41% [ 43 ], 9–20% [ 51 ], 53–92% [ 49 ], 64% [ 39 ].…”

Extraction of Metals from Polluted Soils by Bioleaching in Relation to Environmental Risk Assessment

et al. 2022

Environmental pollution has particular implications for the whole geosystem and increases the global risk to human and ecological health. In this regard, investigations were carried out on soil samples to perform the quality status assessment by determining: pH, texture, structure and metal concentration, as well as carrying out an assessment of anthropogenic activity by determining pollution indices: Cf (contamination factor), Cd (degree of contamination), PLI (pollution load index), Er (ecological risk index) and PERI (potential ecological risk index). Analyses on soil samples showed high concentrations of metals (Cu: 113–2996 mg kg−1; Pb: 665–5466 mg kg−1; Cr: 40–187 mg kg−1; Ni: 221–1708 mg kg−1). The metal extraction experiments were carried out by bioleaching using Thiobacillus ferrooxidans, microorganisms at different amounts of bioleaching solution (20 mL and 40 mL 9K medium) and a stirring time of up to 12 h. The results on the degree of contamination, pollution loading index PLI (2.03–57.23) and potential ecological risk index PERI (165–2298) indicate that the soils in the studied area have a very high degree of pollution. The decontamination procedure by bioleaching showed a decrease, but at the end of the test (12 h), the followed indices indicate high values, suggesting that bioleaching should continue. The depollution yield after 12 h of treatment is, however, encouraging: Cu 29–76%, Pb: 10–32%, Cr: 39–72% and Ni 44–68%. The use of yield–time correlation equations allows the identification of the optimal exposure time on the bioleaching extraction process to obtain optimal results. The aim of the research is to determine the soil quality, soil environmental risk, extraction of metals from polluted soils by bioleaching and to identify influencing factors in achieving high remediation yields.

“…It is also more and more involved in international collaboration, e.g., by participation in research and development projects (R&D) in the field of new technologies of raw material recovery and waste management (under European Institute of Innovation & Technology; EIT Raw Materials). The raw materials recovery sector has had a significant impact on the innovation (including eco-innovations) [61,62] and competitiveness of the national economy through the development and implementation of innovative technologies for waste management [63][64][65] and recovery of raw materials [66,67]. A growing level of processing of secondary raw materials with the use of more and more innovative processing technologies has been observed [68], which could contribute to the improvement of the level of innovation in the Polish economy [69], although the existing processing capacity of the infrastructure in this scope should be assessed as insufficient.…”

Drivers and Barriers for a Circular Economy (CE) Implementation in Poland—A Case Study of Raw Materials Recovery Sector

2021

View full text Add to dashboard Cite

Mobilizing industry and transforming industrial sectors to a circular economy (CE) is one of the key areas of activities in the European Green Deal (EGD)—the newest strategy of economic growth in European Union (EU). In the CE, the raw materials that can be recovered from various waste streams play a key role, therefore, recommendations for their management were developed, both at the European and national level. In Poland, the raw material recovery sector is one of the strategic sectors (key industries) described in several documents determining the further directions of economic growth in the country. This paper presents the revision of these documents and guidelines for the implementation of the CE in the raw material recovery sector. The scope of the paper also includes a description of the current state of the raw materials recovery sector and its return, supported by the analysis of drivers and barriers in its further development. In previous years, a dynamic development of the recovery industry was observed, followed by formation of new companies (dominated by medium-sized companies comprising ~50% of entities in the sector) and increasing amount of people employed (~70,700 people). A growing level of processing of secondary raw materials with the use of more and more innovative technologies has been observed, which could contribute to the improvement of the level of innovation of the national economy. There also some barriers, such as the lack of sufficiently developed industrial symbiosis (IS) and long-term support for the implementation of recovery technologies. The growing ecological awareness of society and enterprises themselves, as well as the growing belief in the importance of resource recovery for environmental protection, suggest the possibility of subsequent development of the raw materials recovery sector. Further actions in this field will be taken to strengthen the implementation of the CE in the country.

“…Among aquatic pollutants, mercury, cadmium, copper, zinc, nickel, lead, chromium, aluminum, and cobalt are considered a priority for removal due to their toxicity [35]. It is possible to effectively remove metals from wastewater and leachate by sorption to very low concentrations in water, using cheap and readily available biowaste [36,37].…”

Industrial human activity has led to the release of substantial amounts of heavy metals into the environment. Contamination of water with heavy metals such as lead, cadmium, copper, zinc, chromium, or nickel represents a serious problem. As part of the circular economy, it is appropriate to use biowaste from agriculture, fisheries, and the timber industry as biosorbents. In this literature review, the potential of using these biowaste groups as biosorbents for metal removal is presented. This biowaste is characterized by the presence of carboxyl, hydroxyl, carbonyl, amide, amine, sulfydryl, and other groups on their surface, which form complexes and chelates with metals present in water. Biosorption seems to be a potential alternative to conventional technologies for removing or recovering heavy metals from water or wastewater, which are uneconomical and generate additional waste. The paper demonstrates that harnessing the potential of biowaste to remove metals is beneficial to the environment as they can solve the problem of incineration and realise recycling that meets the circular economy. Although the choice of a suitable biosorbent for the removal of a particular metal involves a lot of research, the high biosorption efficiency, low cost, and renewability justify their use.
