Thesis (M.Sc.)
Potato peel is a tuber-based biomass produced in huge quantities worldwide , requiring an appropriate management strategy to meet the waste - to-wealth concept The conventional treatment of dye - laden wastewater generates large amounts of sludge with toxic compounds , necessitating sustainable management techniques This thesis addresses the management of potato peel for methylene blue (MB) adsorption and recycling for dual biogas and char production The thesis is broken down into three parts Part one involves the production of biochar from potato peel waste (PPBC) via pyrolysis at 600 °C for 2 h The chemical and physical properties , such as biochar yield , elemental composition , crystallography , surface area , and functional groups, were analyzed and discussed before and after adsorption The effectiveness of the synthesized PPBC was tested for MB removal from an aqueous solution The essential operating parameters were examined and optimized through experimental testing and modelling using Box-Behnken design (BBD) in a response surface approach The optimized time and adsorbent dosage were 55.2 min and 2.6 g/L, giving 81.88% removal at initial MB= 50 mg/L and pH= 9. A verification experiment was conducted under this optimized condition , showing a measured removal percent (R%) of 81.76%. This value complies with the R% predicted by the quadratic model The reusability and regeneration test revealed that PPBC could be used over three cycles without significant loss Part two involves the production of biogas from chicken droppings. The exhausted biochar was regenerated and supplemented to an anaerobic digester using a biochar: chicken droppings (CD) ratio of 1:4 (w/w) at 37 °C for 25 days Gompertz model was established using IBM SPSS Statistic 25 to analyze the cumulative methane production (CMP). The biochar/CD synergy exhibited a bio- CH4 yield of 159.6±10.5 mL/g CODinitial greater than the sole CD digester (as a control) by 32.4%, owing to biochar amendment in the digester Part 3 involves char production from the digestate to maintain a sustainable circular economy The anaerobic digestate was thermally treated at 500 °C for 60 min. The morphological, structural, and chemical properties of the digested char were examined using characterization techniques The generated biochar acquired a yield of 0.62 g/g sludge-cake, exhibiting a heterogenic surface and significant amounts of essential nutrients, which could be further utilized as an effective soil amendment in farmlands
