Hylobius abietis is a plant parasitic insect belonging to the order Coleoptera and which causes severe damages to coniferous forests in Northern and Eastern Europe.This current study is aimed to provide a new viewpoint into the waste of this insect by producing chitosan.Dry insect corpses consisted of 27.9%chitin and 86.2%of the chitin was converted into the chitosan.FT-IR spectra analyses confirmed the purity and the deacetylation degree of the produced chitosan(molecular weight of chitosan;7.3 kDa).This chitosan exhibited antimicrobial activity against 18 bacterial strains.Further,biodegradable chitosan composite films with β-carotene were produced.Antioxidant activity of chitosan films were found to be higher than chitosan gels;andβ-carotene incorporation further increased the antioxidative properties of the chitosan films.This study demonstrated that the waste of parasitic insect like H.abietis can be evaluated as a source for production of biodegradable and edible chitosan-based films for applications in food coating. 展开更多

This study analyzes the potential of an agricultural residue,hazelnut shells,as raw material in a combined ther-mochemical process to obtain pyro-gas and biochar for environmental remediation.The novelty of this study relies on the definition of a pyrolytic polygeneration process to simultaneously attain an energy-type product and abiochar to maximize the versatility of the products and their usage.To this aim,the heating value of the gas and its potential to feed a micro combined heat and power(micro-CHP)system was evaluated.Additionally,the resulting biochar was chemically activated and tested as adsorbent for the removal of contaminants from an aqueous solution.Results show that the pyro-gas from the shell-type residue was suitable to be used as feed stream in a micro-CHP unit,which was able to operate near the full-load(91.9%)with electrical and thermal efficiencies of 27.6%and 57.9%,respectively.In the case of the biochar fraction,poor results were found for the char prior to activation.Instead,once it was activated with KOH,the resulting activated carbon presented high effectiveness as adsorbent and complete removal of the measured compound(methylene blue)was achieved. 展开更多
