“…The gas production continuously increased with increments in temperature from 400 o C to 800 o C. According to Zadeh et al (2021), the maximum bio-oil yield from fast pyrolysis of softwood (spruce) and hardwood (populace) was obtained at 600 o C and 700 o C, respectively. Another study reported an optimum temperature of 550 o C for bio-oil production from swine manure (Wang et al, 2020a). Moreover, Efeovbokhan et al (2020) reported that the bio-oil from pyrolysis of yam peel increased with temperature until 450 o C, and then it started to decline.…”

Thermochemical processes, which include pyrolysis, torrefaction, gasification, combustion, and hydrothermal conversions, are perceived to be more efficient in converting waste biomass to energy and value-added products than biochemical processes. From the chemical point of view, thermochemical processes are highly complex and sensitive to numerous physicochemical properties, thus making reactor and process modeling more challenging. Nevertheless, the successful commercialization of these processes is contingent upon optimized reactor and process designs, which can be effectively achieved via modeling and simulation. Models of various scales with numerous simplifying assumptions have been developed for specific applications of thermochemical conversion of waste biomass. However, there is a research gap that needs to be explored to elaborate the scale of applicability, limitations, accuracy, validity, and special features of each model. This review study investigates all above mentioned important aspects and features of the existing models for all established industrial thermochemical conversion processes with emphasis on waste biomass, thus addressing the research gap mentioned above and presenting commercial-scale applicability in terms of reactor designing, process control and optimization, and potential ways to upgrade existing models for higher accuracy.

“…Improper treatment of swine manure may also result in air pollution by toxic gases (foul odour), soil and water contamination, which can have a significantly negative effect on the environment [64]. Wang et al [64] studied the swine-manure-derived bio-binder. They concluded that the bio binder derived from the swine-manure-derived improves low temperature cracking of an asphalt mix.…”

The global road network spans 64.3million km and is of huge significance for the social and economic development. The level of investment in road construction and maintenance is high, e.g. EU €44billion/year (2019), China €614.7billion/year (2019) and US €94billion/year (2019). Despite the level of investment, there has been minimal investment in the development of new asphalt technologies, particularly when compared with R&D investment in other industries, such as the automotive industry. Despite the limited investment, there have been some innovations in asphalt technology. For the past 20 years, researchers have developed bio-inspired asphalt technology, self-healing and bio-binders and have applied them to asphalt pavements. This research has emerged as a response to global warming and the need to reduce both carbon emissions and reliance on oil in asphalt technology. This paper charts the development of two bio-inspired technologies and considers their significance in relation to the need to reduce carbon emissions and oil dependence (in line with the UN strategic goals, specifically: SDG 9, 11 and 12). This paper considers the potential benefits of bio-inspired technologies and outlines the current barriers to their further development. This paper aims to begin a conversation with stakeholders on how to speed up the acceptance of bio-inspired asphalt technologies and their adoption in road design, construction and maintenance. Or is it the case that we have reached the end of the road for bio-inspired road construction materials?

“…It is renewable, ecofriendly and has rheological properties comparable to conventional asphalt. Bio-oil may be derived from a wide range of biomass sources throughout the globe, including algae (Abdul Latif et al, 2019), switchgrass (Yue et al, 2017), corn stover (Yang et al, 2017), swine manure (Fini et al, 2011;Mills-Beale et al, 2014;Wang et al, 2020b), waste wood resources (Gürer et al, 2020;Ingrassia et al, 2020;Yang et al, 2013;2014) and waste cooking oil (Sun et al, 2016;Wen et al, 2013;Zahoor et al, 2021). Particularly in Malaysia, the extraction of palm oil results in a substantial amount of biomass waste, including mesocarp fruit fibres (MF), palm kernel shells (PKS), palm oil mill effluent (POME), and empty fruit bunches (EFB).…”

Bio-asphalts feature economic, social, and environmental benefits and may thus be potentially substituted for petroleum-based asphalt in asphaltic concrete mixtures. This article presents the experimental investigation of adding palm bio-oil derived from empty fruit bunches (WBO) into the conventional asphalt binder at 5, 10 and 15 wt%. The physical properties of bio-asphalt were assessed via the penetration, softening point, rotational viscosity, ductility, and mass loss after the rolling thin-film oven (RTFO) tests. Fourier-transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS) tests were used to identify the chemical composition and functional groups of the bio-oil and bio-asphalt samples. The binder coatability was assessed by static water immersion and water boiling tests. The addition of bio-oil lowers the softening point and viscosity of the binder while increasing its penetration, ductility and mass loss after RTFO. The main absorption peaks for WBO bio-oil and WBO bio-asphalts were corresponding to C=H stretching of alkanes and aliphatic compounds, respectively. The bio-oil was mostly composed of aromatic and oxygenated compounds, as observed from GC-MS results, which justified the FTIR analysis for WBO bio-oil. The addition of WBO bio-oil improved the bonding characteristics of asphalt-aggregates, indicatingthat it has a significant potential for use in the production of bio-asphalt.
