“…This fact demonstrates that the addition of PS to the GSs feedstock synergistically promotes the formation of aromatic compounds [45]. These results agreed with the literature [7,14,46] where it was demonstrated that PS incorporation into lignocellulosic biomass improved the quality of the upgraded bio-oil, due to transformation of oxygenated compounds into aromatic…”

Co-pyrolysis of grape seeds and polystyrene was conducted in a fixed-bed reactor, followed by an analysis of the organic phase for possible further application as a drop-in fuel. Significant positive synergistic effects were found with the addition of polystyrene (5-40 wt%) to the conventional pyrolysis of grape seeds. There was a considerable improvement in the organic phase yield, in particular, reaching values over 80 wt%, markedly higher than those obtained from conventional pyrolysis (61 wt%). Fuel properties of the bio-oil were also upgraded, with a decrease in oxygen content and an increase in the heating value. An organic bio-oil fraction with pH values ranging from 5.4 to 6.2 was obtained, reducing the issues associated with handling bio-oils obtained from common pyrolysis of lignocellulosic biomass, usually ranging between 2 and 3. Finally, an increment in the desired compounds, mainly aromatics, was also attained, while at the same time achieving a low content of undesired compounds, such as phenols. It was demonstrated that polystyrene can act as a H 2-donor, favoring oligomerization, cyclation and hydrodeoxygenation reactions into aromatic compounds.

“…The calori c value increased from 32 MJ/ Kg for SB bio-oil to 41.05 MJ/kg for SB: TW co-pyrolysis liquid product. The calori c value of the copyrolysis liquid product was found a little higher than the range of values reported in the literature by (Suriapparao et al 2018). The elemental analysis results manifested an improved 'C' content (82.15%) in the case of co-pyrolysis liquid product as compared to SB thermal pyrolysis bio-oil (65.64 %).…”

The current study explores co-pyrolysis of sugarcane bagasse, and thermocol waste in a semi-batch reactor to evaluate the in uence of temperature, and blending ratio on yield of products, and reaction time, and thereby characterize the maximum liquid product. The properties of liquid product (bio-oil), and the solid product (bio-char) obtained from thermal sugarcane bagasse, and co-pyrolysis sugarcane bagasse: thermocol waste bio-oil were investigated for physicochemical characterizations. The compositional analysis result of the co-pyrolysis liquid product established the presence of several aromatic compounds. The co-pyrolysis liquid product manifested a higher calori c value, carbon, and hydrogen content as compared to sugarcane bagasse thermal pyrolysis bio-oil. The co-pyrolysis liquid product can be used as a liquid fuel in internal combustion engines, as well as a precursor for valueadded chemicals. The properties of bio-char suggested it can be used as a solid fuel, as well as an adsorbent.

“…It has been shown that the mixed waste biomass and plastics resi-dues can be converted into more valuable products than that obtained from pyrolysis of individual components. The higher heating value (HHV) of co-pyrolysis bio-oil obtained from biomass (rice husk, wood sawdust, groundnut shell, bagasse) and plastic (polypropylene, polystyrene) blends was high (38-42 MJ/kg) compared to bio-oil obtained only from biomass pyrolysis (20-30 MJ/kg) [13]. The presence of polystyrene boosted the production of aromatic hydrocarbons, while polypropylene promoted aliphatic hydrocarbons in co-pyrolysis bio-oil.…”

Two promising techniques-anaerobic digestion (AD) and microwave pyrolysis (MP)-have been presented in this work for possible recycling of organic waste. The main products of AD are biogas and digestate, which can be utilized for production energy, fuels and valuable materials. MP products are gases, liquids and char, which can be used as substrates for producing hydrogen, biodiesel, kerosene, and activated carbon. MP provides fast heating and can be used for various material waste blends including biomass-plastic mixtures. AD and MP can be combined for a synergic effect with respect to system efficiency.
