“…Abnisa et al [23] found that higher percentages of PS in the feedstock resulted in higher liquid yields, whilst gas and solid fractions decreased, with the biomass-to-PS ratio being the most significant variable on the distribution of products. Similar results were obtained by Shadangi et al [21]. These authors also reported that the largest liquid yields were attained from the highest amounts of PS in the feedstock.…”

“…In line with this, Pinto et al [49] concluded that co-pyrolysis of PS and rice crop wastes led to a higher yield of aromatic hydrocarbons in the final liquid. Likewise, Shadangi et al [21] found that using a karanja and niger seeds-to-PS ratio of 2, the resulting bio-oil mainly consisted of aromatics such as benzene, toluene and styrene, and a small group of oxygenates such as esters and acids.…”

“…Shadangi et al [21] studied co-pyrolysis of PS wastes with two types of biomass in different proportions using a semi-batch lab-scale. The results confirmed that this process had a positive influence on the yields and quality of the oil, which was especially reflected in improved viscosity and a higher heating value of the upgraded bio-oils.…”

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.

“…On pyrolysis of plastic by mixing biomass causes the improvement in liquid product yield than the plastics pyrolyzed individually (Brebu, 2010). Copyrolysis of plastic waste with different biomass such as karanja & niger seeds (Shadangi, 2015), red oak (Xue, 2015), rice husk (Costa, 2014), almond shell (Önal, 2013), oil shell (Aboulkas, 2012), pine cone (Brebu, 2010), wood biomass (Sharypov, 2002), forestry biomass wastes (Paradela, 2009), lignocellulosic materials (Jakab, 2001) has been studied widely. Oxidative thermal degradation of the waste High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) by mixing Jute fiber is a novel pathway to obtained high yield of liquid fuel from polyethylene waste (Dixit, 2016).…”

“…Plastic with higher hydrogen content could be used as a hydrogen donor in co-pyrolysis with biomass or coal of less hydrogen content, which could balance the carbon, oxygen, and hydrogen in the feedstock. This process could result in a strong upgrading effect on its derived product, such as bio-oil and bio-char (Shadangi and Mohanty 2015). Previous studies have demonstrated that co-pyrolysis of biomass with plastic results in an increase in bio-oil yield and an improvement in bio-oil quality (Onal et al 2014).…”

Bio-chars were produced by co-pyrolysis of lignin with high-density polyethylene at 350 °C, 450 °C, and 550 °C. X-ray diffraction (XRD), Raman spectroscopy, automated surface area and pore size analysis, scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and electron spin resonance (ESR) spectroscopy were performed on bio-char to reveal the effect of temperature on its physical structure and chemical properties. All of the bio-chars demonstrated a highly disordered, turbostratic structure and exhibited a wide pore distribution. Dramatic losses of carbonyl, hydroxyl, and C-H groups indicated the development of condensed aromatic structure in the bio-chars. Specifically, biochar produced at 450 °C showed the highest degree of aromaticity, which is the relative content of aromatic structure with small fused rings and free radical concentration. This structure has more potential application in composite production and as solid fuel for its combustion or gasification. Moreover, biochar produced at 550 °C had the greatest porosity development, favoring its use as a precursor for activated carbon production.
