TL;DR: In this article , microwave-assisted pyrolysis, supercritical water gasification, and plasma gasification are compared to highlight their advantages and limitations in process and techno-economic feasibility.
Abstract: ABSTRACT Growing non-biodegradable waste plastics pose a significant environmental challenge that cannot be addressed by conventional methods alone. Therefore, alternative waste management methods such as plastic-to-fuel methods that convert waste plastics into valuable biofuels via thermochemical degradation must be investigated. Waste plastic pyrolysis and gasification are popular plastic-to-fuel technologies that will be instrumental in circular economies. Therefore, they must be discussed and compared to highlight their advantages and limitations in-process and techno-economic feasibility. Thus, this paper tries to reach three technologies: microwave-assisted pyrolysis, supercritical water gasification, and plasma gasification, highlighting their strengths and weaknesses. It appears that the diesel-like pyrolysis oil from microwave pyrolysis can be used in internal combustion engines to mitigate fossil fuel dependence. Moreover, gasification technologies could help in the growth of integrated biorefineries that can extract hydrogen from syngas to produce value-added chemicals. It is anticipated that their industrial-scale implementation could be beneficial for landfill reclamation and mitigation of plastic-related environmental harm. However, these technologies are currently at low technology readiness levels. Therefore, more studies are required to spotlight their in-depth techno-economic feasibility and provide a research direction to economize these technologies further to maximize their economic rate of return.

TL;DR: In this article, the authors explored co-pyrolysis of sugarcane bagasse and thermocol waste in a semi-batch reactor to evaluate the influence of temperature, and blending ratio on yield of products, and reaction time, and thereby characterize the maximum liquid product.
Abstract: The current study explores co-pyrolysis of sugarcane bagasse, and thermocol waste in a semi-batch reactor to evaluate the influence 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 calorific 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 value-added chemicals. The properties of bio-char suggested it can be used as a solid fuel, as well as an adsorbent.

TL;DR: A review of the recent developments in the wood pyrolysis and reports the characteristics of the resulting bio-oils, which are the main products of fast wood pyrotechnics, can be found in this paper.
Abstract: Fast pyrolysis utilizes biomass to produce a product that is used both as an energy source and a feedstock for chemical production. Considerable efforts have been made to convert wood biomass to liquid fuels and chemicals since the oil crisis in mid-1970s. This review focuses on the recent developments in the wood pyrolysis and reports the characteristics of the resulting bio-oils, which are the main products of fast wood pyrolysis. Virtually any form of biomass can be considered for fast pyrolysis. Most work has been performed on wood, because of its consistency and comparability between tests. However, nearly 100 types of biomass have been tested, ranging from agricultural wastes such as straw, olive pits, and nut shells to energy crops such as miscanthus and sorghum. Forestry wastes such as bark and thinnings and other solid wastes, including sewage sludge and leather wastes, have also been studied. In this review, the main (although not exclusive) emphasis has been given to wood. The literature on woo...

TL;DR: In this article, the authors reviewed scientific and technical developments in applications of bio-oil to date and concluded with some suggestions for research and strategic developments, and concluded that biooil is a renewable liquid fuel and can also be used for production of chemicals.
Abstract: Fast pyrolysis of biomass is one of the most recent renewable energy processes to have been introduced. It offers the advantages of a liquid product, bio-oil that can be readily stored and transported. Bio-oil is a renewable liquid fuel and can also be used for production of chemicals. Fast pyrolysis has now achieved a commercial success for production of chemicals and is being actively developed for producing liquid fuels. Bio-oils have been successfully tested in engines, turbines, and boilers, and have been upgraded to high-quality hydrocarbon fuels, although at a presently unacceptable energetic and financial cost. The paper critically reviews scientific and technical developments in applications of bio-oil to date and concludes with some suggestions for research and strategic developments.

TL;DR: The wet pyrolysis process, also known as hydrothermal carbonization, opens up the field of potential feedstocks for char production to a range of nontraditional renewable and plentiful wet agricultural residues and municipal wastes as discussed by the authors.
Abstract: The carbonization of biomass residuals to char has strong potential to become an environmentally sound conversion process for the production of a wide variety of products. In addition to its traditional use for the production of charcoal and other energy vectors, pyrolysis can produce products for environmental, catalytic, electronic and agricultural applications. As an alternative to dry pyrolysis, the wet pyrolysis process, also known as hydrothermal carbonization, opens up the field of potential feedstocks for char production to a range of nontraditional renewable and plentiful wet agricultural residues and municipal wastes. Its chemistry offers huge potential to influence product characteristics on demand, and produce designer carbon materials. Future uses of these hydrochars may range from innovative materials to soil amelioration, nutrient conservation via intelligent waste stream management and the increase of carbon stock in degraded soils.
