“…The third peak at 700-750 • C was attributed due to the decomposition of the residues. Similar trends were also observed in manure pyrolysis [41,44]. After 750 • C, the DTG curve has stabilized and the final residue has stayed in the range of 30-40%.…”

In this study sustainable valorization of cattle manure, recycled polyester, and their blend (1:1 wt.%) were examined by the thermogravimetric analysis (TGA) method. Pyrolysis tests were performed at 10, 30, and 50 °C/min heating rate from room temperature to 1000 °C under a nitrogen environment with a flow of 100 cm3/min. Kinetics of decomposition were analyzed by using Flynn–Wall–Ozawa (FWO) method. Based on activation energies and conversion points, a single region was established for recycled polyester while three regions of pyrolysis were obtained for cattle manure and their blend. Comparison between experimental and theoretical profiles indicated synergistic interactions during co-pyrolysis in the high temperature region. The apparent activation energies calculated by FWO method for cattle manure, recycled polyester. and their blend were 194.62, 254.22 and 227.21 kJ/mol, respectively. Kinetics and thermodynamic parameters, including E, ΔH, ΔG, and ΔS, have shown that cattle manure and recycled polyester blend is a remarkable feedstock for bioenergy.

“…After the drying step, solid digestates can be converted into pellets for combustion 107,120 . Combustion is a thermochemical process based on the complete oxidation of organic wastes to produce energy in the form of heat 121 . Net calorific values of digestate pellets varying between 16.5 and 17.3 MJ kg -1 DM have previously been reported 120 .…”

“…However, the pyrolysis of lignocellulosics carry some limitations: (i) derived pyrolysis bio-oil contains an abundance of oxygenated compounds and (ii) the bio-oil is too acidic [13]. Aside from lignocellulosic materials, other suitable feedstocks for pyrolysis include N-containing wastes, such as algae [14], manure [15,16], potato peel [17], and activated sludge [18][19][20][21][22][23]. Of these, activated sludge is arguably the most similar to RBB, due to both being comprised primarily of bacteria.…”

a b s t r a c tPolyhydroxyalkanoate (PHA) production generates a significant amount of residual bacterial biomass (RBB) after PHA extraction. The RBB as a zero-value waste contains proteins, carbohydrates, phenolics, and ash, which can be managed and converted to bio-oil and biochar products by pyrolysis. Thermogravimetric analysis (TGA) was used to investigate the thermodegradation kinetics of RBB and pyrolysis-GCMS studies were employed to determine potential chemical products. Pyrolysis was conducted on a laboratory-scale auger reactor at 500 • C. The bio-oil and biochar yield were 28 and 46%, respectively. The pyrolysis bio-oil was characterized by the combination of GCMS, high-pressure liquid chromatography (HPLC), and electrospray ionization mass spectrometry (ESI-MS). The bio-oil was dominated by nitrogen-containing, hydrocarbons, and aromatic compounds. The biochar was studied for its specific surface area and pore size, chemical functionality by Fourier transform infrared (FTIR) and Raman spectroscopies, and butane absorption activity. Biochar was comprised of a large part of polycondensed phenolic and majorly disordered amorphous carbon.
