“…These elemental results are clearly in the range for a mixture of lignocellulosic biomass such as cardboard and plastic or wax 12,15,30,31 . The small amount of ash (2.1%) may have come from inorganic additives such as talc 32,33 . The low N content (0.1%) confirms that the WCCB has very little protein.…”

Corrugated cardboard (CCB) comprises a substantial portion of municipal solid waste, of which ~5% is wax coated CCB (WCCB) to enhance its performance. WCCB cannot be recycled, making it a suitable resource to recover wax and produce char. The WCCB was characterized for its extractable wax, lignin, and carbohydrate contents and by thermogravimetric analysis to study its thermal degradation behavior. WCCB was preliminarily examined by pyrolysis‐gas chromatography–mass spectrometry to determine product composition. WCCB samples were then pyrolyzed in auger and tube reactors at 450, 500, and 550°C, and their pyrolysis wax‐oil and char products characterized. WCCB and char were subjected to proximate, ultimate, surface area, analyses. The highest char yield was 36% at 450°C, and the highest wax‐oil yield was 53% at 550°C in the tube reactor. The wax‐oil fraction contained mainly alkanes, alkenes, and dienes (C9–C36), and chain length decreased with pyrolysis temperature. This wax fraction could be recovered and used as bunker fuel (C12–C40) or further converted to diesel (C10–C20).

“…Previous studies related to the pyrolysis of cellulose demonstrated that anhydrosugars, furans, aldehydes, and ketones were the predominant products in bio-oils. − However, phenol and alkyl-phenols were also detected in some previous reports, in which the pyrolysis of cellulose was performed. , It was concluded that phenols were formed directly from glucose units. Benzene derivatives were also observed in WTP-derived oil, but WMO-derived oil contained alkanes and alkenes. The major compound in the WMO-derived oil was found to be tricosane.…”

Influence of Co-Pyrolysis of Waste Tetra Pak with Waste Motor Oil on Product Distribution and Properties for Fuel Application

In this work, waste tetra pak (WTP) and waste motor oil (WMO), with different blend ratios of WTP/WMO (4:1, 2:1, 1:1, 1:2, 1:4) were subjected to co-pyrolysis at 500 °C. For the purpose of comparison, individual pyrolysis of WTP and WMO was conducted under identical conditions. Pyrolysis/co-pyrolysis products were collected as liquids (containing an oil phase and an aqueous phase), solid residue, and gaseous products. The highest oil yield was 72.14 wt % and was obtained at a blend ratio of 1:4 (WTP/WMO). Synergistic effects on oil yields were observed in all blends. Heating values of the oils from blends ranged from 45.2 to 46.1 MJ kg −1 . The heating value of the gas product obtained from the co-pyrolysis of WTP with WMO at a blend ratio of 1:1 (WTP/WMO) was 24.5 MJ Nm −3 . Heating values of the solid residue ranged from 24.2 to 26.7 MJ kg −1 , comparable to that of sub-bituminous coal. These results suggest that WTP could be co-pyrolyzed with WMO to produce liquid, solid, and gaseous fuels.

“…The research about the potential risk of biochar remained to be a hotspot. The research on biochar risk was shifted from plant and soil fauna to enzymatic activity and microbial population (Mierzwa-Hersztek et al 2016Oleszczuk and Koltowski 2018;Raclavska et al 2018). Enzymatic activity and microbial population were considered as sensitive and effective bio-indicators, and important for the assessment of the potential risk of biochar amendment into soil (Mierzwa-Hersztek et al 2017).…”

Biochar is the carbon-rich product obtained from the thermochemical conversion of biomass under oxygen-limited conditions. Biochar has attained extensive attention due to its agronomical and environmental benefits in agro-ecosystems. This work adopts the scientometric analysis method to assess the development trends of biochar research based on the literature data retrieved from the Web of Science over the period of 1998-2018. By analysing the basic characteristics of 6934 publications, we found that the number of publications grew rapidly since 2010. Based on a keyword analysis, it is concluded that scholars have had a fundamental recognition of biochar and preliminarily found that biochar application had agronomic and environmental benefits during the period of 1998-2010. The clustering results of keywords in documents published during 2011-2015 showed that the main research hotspots were "biochar production", "biochar and global climate change", "soil quality and plant growth", "organic pollutants removal", and "heavy metals immobilization". While in 2016-2018, beside these five main research hotspots, "biochar and composting" topic had also received greater attention, indicating that biochar utilization in organic solid waste composting is the current research hotspot. Moreover, updated reactors (e.g., microwave reactor, fixed-bed reactor, screw-feeding reactor, bubbling fluidized bed reactor, etc.) or technologies (e.g., solar pyrolysis, Thermo-Catalytic Reforming process, liquefaction technology, etc.) applied for efficient energy production and modified biochar for environmental remediation have been extensively studied recently. The findings may help the new researchers to seize the research frontier in the biochar field.
