“…Many authors gave TG curves for biomass, wood and different types of plastics [75]- [77], [80], [85], [89], [92], [100], [107], [116], [117], [119], [121]- [124]. Figure 6 gives the TG and DSC curves as a function of temperature of HDPE, PS, PVC and for poplar wood (PW) and a waste wood sample (W3).…”

“…This means that the experimental values, for example the gas, oil or char yield, or the gas composition, differ from those calculated by linear interpolation on the basis of the results for the pure components in the feedstock. The mechanisms of these synergistic effects were studied by different authors [75]- [77], [79], [80], [86], [89], [92], [96], [100], [102], [107], [115]- [117], [121], [122], [138], [145] . Plastics (PS, PE, PP, PET, PVC) devolatilise in a higher temperature range (300-500°C) than biomass (200-400°C) (see 3.2.…”

“…PET and PS produced lower olefin concentrations. Biomass/PS mixtures and biomass/PET mixtures, behave in a different way than biomass/polyolefines mixtures during thermal conversion [92], [100], [121], [138]. For PET, a variety of oxygen-containing products and aromatic hydrocarbons are released upon degradation.…”

Waste Biomass Valor

Over the past few decades, the sharp rise in post-consumer plastic and biomass waste has resulted in an ever growing challenge to treat such waste sustainably. Co-pyrogasification of plastics and biomass mixtures, as opposed to separately converting these waste streams, offers several advantages including an improvement in syngas quality and composition (H2/CO ratio) in relation to the desired application, and an easier reactor feeding of plastics. Furthermore, many studies have shown that co-pyrogasification promotes the conversion of waste to gas rather than char and tar. However, in order to achieve the desired product distribution or syngas composition, operating parameters such as the reactor temperature, equivalence ratio (air or oxygen), steam/fuel ratio and catalyst, have to be optimized. Thus, this paper aims to review literature studies on the co-pyrogasification of plastics and biomass by considering various aspects including the process principle, reactors, influence of feedstock characteristics and operating parameters on the products, as well as the synergies observed during the thermoconversion of plastics and biomass mixtures with some reference to coal mixtures when necessary.

“…Biomass is the only renewable carbon resource that can be directly converted into fuel [2]. Especially in the last decade it has attracted more attention as a low risk and capital required renewable energy source [3][4][5][6]. Biomass is an abundant energy resource accounting for 9% of electricity consumption in the world in 2015.…”

“…The synergism in co-pyrolysis is seen as an increase in product yield, improvement in product characteristics, and decrease in emissions [21]. In many studies synergy during co-pyrolysis has depicted by the higher weight loss than the theoretical values calculated via a weighted average of single materials [3,36]. In some studies, however, a negative impact of co-pyrolysis on volatiles yields has observed [37].…”

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.

Co‐pyrolysis of bamboo and plastic powder was conducted in order to investigate how to produce “ecological” solid fuel. The mixing percentage of the powders wp and the setting temperature of the reactor wall TS were changed. At TS = 573 K the decomposition of the simulated waste plastic was progressed on the surface of the bamboo char during co‐pyrolysis while the tar from bamboo pyrolysis was wrapped by the molten plastic. The pores on the surface of the bamboo particles decreased with wp because they could be wrapped by the molten plastic. The particle size increased with wp. On the other hand, at TS = 673 K the co‐pyrolysis of bamboo and simulated waste plastic was disturbed partly by the interaction during co‐pyrolysis of polypropylene (PS) and Polyethylene terephthalate while the co‐pyrolysis of bamboo and PS was progressed. The grindability increased with TS and decreased with wp as most of the molten plastic coagulated after co‐pyrolysis because the shape of particles changed from small fibrous particles to large granular particles with wp. At 30 wt% < wp < 70 wt%, the higher heating value (HHV) at TS = 673 K was mostly lower than that at TS = 573 K because the char yield in the mixture was lower than that of the expected char yield due to the progress of the simulated waste plastic pyrolysis at TS = 673 K. The energy yield had a local minimum value at wp = 10 wt% because the char yield increased by the coating of molten plastic during co‐pyrolysis even if the TS increased. The energy yield decreased with TS. The optimum condition for the solid fuel, which was evaluated by grindability, HHV, and energy yield was TS = 623 K and wp = 10 wt%.
