Full textThe increase of waste from electric and electronic equipment has pushed the research towards the development of high sustainability treatments for their exploitation. The end-of-life printed circuit boards (PCBs) represent one of the most significant waste in this class. The interest for these scraps is due to the high Cu and Zn concentrations, around 25% and 2% respectively. Biohydrometallurgical strategies are gaining increasing prominence, for the possibility to decrease the environmental costs. Nevertheless, these techniques show the main limit due to the low treated PCB amount, which makes unsustainable the further scale-up. To overcome this criticality, the present research introduces an innovative bioleaching process carried out by At. ferrooxidans. The developed technology allows to reach high PCB concentration thanks to a high efficiency two-step design, able to reduce the metal toxicity on the bacteria metabolism. The treatment uses the Fe3+ generated by bacterial oxidation, as oxidant, to leach Cu and Zn from PCBs. The possibility to overcome the solid concentration criticality is combined with high yield of 95% for Cu and Zn. The best selected conditions are: 30°C, pulp density of 5% (w/v), 10 g/L of Fe2+, time of treatment 11 days. A mathematical model to study the kinetic of the chemical reaction for the Cu leaching from PCBs, by Fe3+, is reported and an activation energy of 18-25 kJ/mol is estimated. The mechanism of the bioleaching process is studied in detail, integrating the previous model results with two differential equation to describe the bacteria growth and metabolism rate. The developed model is consistent with a R2 higher than 0.97. The results confirm the positive effect of the new innovative process. The determined mathematical model, suitable for the implementation at industrial scale, could be an important tool to predict the bioleaching mechanism. In the next step, the research is focused on the selective metal recovery from the leaching solution. The best identified conditions include: the Fe precipitation with NaOH, followed by the Cu cementation with Zn and a final Zn precipitation with oxalic acid. The metals show recovery efficiencies and purities higher than 95%. The experimental results are further enhanced by the carbon footprint assessment which proved the environmental advantage, compared to both the reference chemical treatment through Fe3+ and literature processes (hydrometallurgical and bioleaching approaches). The environmental impact assessment drives the optimization and improvement of the developed process in laboratory scale. It is used to identify the best conditions for the bioleaching process able to make the treatment actually sustainable. Overall, the environmental assessment identifies, as main criticalities to solve: the high energy demand of bioleaching process and the raw materials demand of the following recovery steps. These preliminary results have determined the choices in the further experiments. More in detail, the bioleaching process is improved by the increase of treated PCB concentration from 5% to 10% (w/v) maintaining a leaching efficiency higher than 95% for Cu and Zn. This technical improvement is translated into the halved of energy demand. Furthermore, the environmental load of recovery can be reduced by a double strategy: avoiding Zn recovery or substituting the hydrometallurgical techniques by electrochemical approaches. In the last chapter, a sustainable process, which uses the fungal strain Aspergillus niger for metal extraction from PCBs, is described. The best identified conditions are PCB addition after 14 days, Fe3+ as oxidant agent, and a pulp density of 2.5% (w/v). Extraction efficiencies of 60% and 40% for Cu and Zn, respectively, are achieved after 21 days of fermentation. The ecodesign of the process is further enhanced by using milk whey as substrate for the fungal growth and the consequent citric acid production.

Full textLignocellulose is the major structural component of woody and non-woody plants, representing a major potential source of renewable organic matter. Lignocellulose is primarily composed by two carbohydrate polymers, cellulose and hemicellulose and by lignin (an aromatic polymer). These complex polymers on the one hand often constitute a residual biomass of agro-food production chain, but at the same time they contain different sugar monomers and phenolic precursors, harbouring an enormous biotechnological value, since they can potentially be converted into different value-added products. In a scenario where the world population is increasing together with the generation of waste and pollution at the expenses of planet resources and human wellbeing, this project aims at proposing an example of circular bioeconomy and industrial symbiosis. More in detail, the project starts from the quali-quantitative evaluation of residual agricultural biomasses to the valorization of a subset of interest for our territory into folates, exploiting yeasts as microbial cell factory. Folate (Vitamin B9) is a water-soluble B vitamin with important roles in nucleic acid synthesis, repair and methylation, produced only by green plants and some microorganisms: for these reasons it represents an essential nutritional component for humans. Vitamin B9 commercially available is chemically synthetized as folic acid, suboptimal in terms of bioactivity for humans; the production of natural folates by microbial fermentation is therefore becoming a sustainable and desirable alternative for human supplementation. During the project the ENEA methodology for the analysis of resource flows and for the creation of possible synergies between the various companies present in the Lombardy region was acquired and applied. Thanks to this work it was possible to identify the main waste biomasses produced in the area in the agro-food sector and unfermented grape marcs was then selected for further studies in laboratory, and compared with previously utilised residual biomasses, deriving from sugar process of production. The non-conventional yeast Scheffersomyces stipitis was exploited as natural but never investigated host for the production of vitamin B9. The growth was optimized and folate production was assessed first in shake flasks and then in bioreactor in formulated media mimicking lignocellulose hydrolysates. The maximum folate production was 3.7 ± 0.07 mg/L, which to date is the highest reported when considering wild type microorganisms. Moreover, folate production was evaluated in shake flasks starting from three different residual biomasses: sugar beet molasses (SBM), sugar beet pulp (SBP) and unfermented grape marcs (UGM). S. stipitis was able to metabolize these biomasses, reaching folate titers of 188.2 ± 24.86 μg/L, 130.6 ± 1.34 μg/L and 101.9 ± 6.62 μg/L respectively. In parallel, the yeast Saccharomyces cerevisiae, amenable for genetic manipulation, was engineered into the anabolic pathway of folate production to acquire novel knowledge on possible targets for unlocking bottlenecks of production. Eight different genes were manipulated for the first time in the same genetic background and exploiting different engineering strategies. This was pivotal for testing the best strain in bioreactor and in bringing folate production and productivity up to 620.0 ± 12.30 μg/L and 41.33 μgfol/Lh respectively, among the highest in the literature. Overall, these results provide solid evidence of possible up-cycling microbial-based processes of lignocellulosic biomasses that characterize specific territory. The value in terms of circularity of the resources, minimization of management costs of wastes and generation of values in the logic of industrial symbiosis was demonstrated, matching the initial scope of the PhD project.
