“…Annually 1.3-1.6 billion tonnes of MSW is generated with a composition of 25-30% of paper and cardboard, 26-35% of organic waste, 5-12% of metal and glass, 7-10% of plastics and 2-4% of wood, textile and rubber (Glushkov et al 2018). The amount of MSW could exceed 2.2-2.4 billion tonnes per year by 2025 (Veses et al 2020). About a quarter of biomass-rich MSW is utilized; meanwhile, the remaining part is sent to landfilling or incineration (Gabbar et al 2018).…”

In this study, two-step pyrolysis of biomass-rich municipal solid waste was studied on nickel supported ZSM-5 catalyst. In the first stage of the reactor, constant temperature (T = 550 °C) was applied, and in the second stage, the reactions took place at 500, 700 and 850 °C. Effects of operating parameters (temperature = 500, 700, 850 °C, steam rate = 1, 5 g/h) and catalyst load (0.5, 1.0, 2.0) were studied on yields and compositions, particularly on the hydrogen contents. In order to determine the significance of the operating parameters, response surface methodology was used. Considering the experimental data, the values of hydrogen/carbon monoxide molar ratio, lower heating value and the simulation, it was found that the favourable operating parameters of two-step pyrolysis of biomass-rich municipal solid waste were 850 °C temperature and 1 g/h steam rate (gas yield: 27.1%, hydrogen yield: 9.96 mmol g−1 waste, hydrogen/carbon monoxide molar ratio: 1.8). From the data of response surface methodology, it was also concluded that temperature has a more critical effect on gas yields and composition than steam rate. However, in some cases, the synergistic effect of the two factors can also be significant. Graphical abstract

“…Among the thermochemical processes, two-step pyrolysis seems to be a promising method because of the improved contact between the derived pyrolysis products and catalyst and the higher hydrogen content of the produced syngas (Veses et al 2020).…”

The presented study assessed the effect of bovine (BC) and fish (FC) waste-derived collagen, poly(hexamethylenebiguanide) hydrochloride (PHMB) and waste dolomite on the emergence of seedlings, growth and development of pea (Pisum sativum L. ‘Lasso’) plants. The seed coating method was used to apply the binding agents. Some of the studied agents were showed to significantly affect the index of emergence velocity (IEV) and of emergence synchrony (IES), but not the final emergence percentage (FEP). The results showed that treatment of the pea seeds with BC, FC and PHMB had a slightly positive effect on plant growth, whereas negative effects of dolomite were observed, i.e., detrimental differences in morphological traits of stipules. Moreover, BC, FC and PHMB improved maximal efficiency of PSII (FV/FM) and did not negatively influence chlorophyll content. Analyses demonstrated positive effects of FC and PHMB and negative ones of BC and dolomite on elemental composition of roots and shoots of the studied plant species. We suggest that the FC and PHMB can be used as promising agents for improvement of plant growth, whereas usage of BC and dolomite should be limited.

“…Comportamento semelhante foi observado quando comparado o valor de PCI encontrado pela amostra (12,7 ± 1,1 MJ Nm -3 ), com o processo de gaseificação para as amostras de CDR (9,9 ± 1,0) e resíduos sólidos municipais (5,5) avaliados por (AGON et al, 2016;CHAN et al, 2019), respectivamente. O valor de PCI da amostra de garrafas PET é semelhante ao encontrado por Veses et al (2020) ao analisar amostras de resíduos sólidos municipais (17,0 ± 4,7 MJ N m -3 ).…”

“…Para as amostras de resíduos sólidos municipais avaliada por Chan et al (2019), o valor encontrado de PCI do gás de síntese gerado durante o processo de gaseificação foi de 5,5 MJ Nm -3 , enquanto que Veses et al (2020) encontraram um valor de 17,0 ± 4,7 MJ Nm -3 , valores estes bem diferentes ao encontrado neste estudo (25,5 MJ Nm -3 ), Tabela 26. Esta discrepancia pode estar associada ao tipo de processo utilizado (pirólise), temperatura, pressão, tipo de reator, composição da matéria prima e até mesmo ao processo de pré-tratamento realizado nas amostras.…”

Thermochemical processes (pyrolysis and gasification) are alternatives that minimize and convert fuel derived from solid urban waste (CDRSU) into energy, as combustible gases such as CO, H2 and C1-C6 and other non-combustible gases can be generated fuels: CO2, N2, O2, etc. Therefore, this work reports for the first time a method for the simultaneous determination of H2, O2, N2, CO, CO2, CH4, C2H2, C2H4, C2H6, C3H4 (propadiene and propyne), C3H6, C3H8 and C4H10 (n-butane and iso). -butane) by gas chromatography (GC) using thermal conductivity (DCT) and flame ionization (DIC) detectors. GC/DCT/DIC separations were obtained in a capillary column (0.32 mm internal diameter, 30 m long and 15 µm porous film layer thickness). The method was optimized and validated according to the protocols recommended by the National Institute of Metrology, Standardization and Industrial Quality (INMETRO) in Brazil. Under the optimized chromatographic conditions, the determination of the number of moles of the analytes ranged from 1.410 5 to 4.110 4 moles with a value of r 0.99 in its linear range and the limits of quantitation ranged from 1.410 5 to 2.710 4 mols (depending on the analyte). Furthermore, it was demonstrated that the method developed by CG/DCT/DIC can be applied to quantify these analytes during the pyrolysis process of CDRSU, PET bottles and PS cups, as it showed high accuracy, with recoveries ranging from 98-101%, and high precision, with a relative standard deviation of less than 2%.
