Solid Waste as a Renewable Source of Energy: A Comparative Study on Thermal and Kinetic Behavior of Three Organic Solid Wastes

Abstract

Pyrolytic characteristics of three different organic solid wastes, municipal solid waste (MSW), digested MSW (DMSW), and digested swine manure (SWD), were investigated at heating rates of 10, 15, and 20 °C min–1 in a thermogravimetric analyzer coupled with mass spectrometer. Three stages of devolatilization, dehydration (0–200 °C), decomposition of major structural components (200–500 °C), and decomposition of solid residue (500–800 °C), appeared during the pyrolysis of all the samples. The major devolatilization stage (stage II) is characterized with three peaks at 319, 379, and 438 °C for MSW, two peaks at 339 and 430 for DMSW, and one peak with a shoulder on the right at 332 and 444 °C for SWD, respectively. The evolved gas species were quantified by using a semiquantitative approach, and H2, CO and CO2 were noticed to be predominant gas species in the above-mentioned range. While the evolution of H2 is mostly temperature dependent, the evolution of CO and CO2 occurred all through the run. Isoconversional methods along with compensation effect and master plots were used to determine the kinetic triplet for the pyrolysis process. The mean activation energies were 172.02–172.3, 202.21–202.55, and 213.84–215.22 kJ mol–1, while the pre-exponential factors were 1.81 × 1010, 1.04 × 1018, and 2.26 × 1019 for MSW, DMSW, and SWD, respectively.

Production and characterisation of activated carbon and carbon nanotubes from potato peel waste and their application in heavy metal removal.

“…This reliance brings with it the environmental concerns that are often attributed to products produced via these means, such as CO 2 emissions. Therefore, study into alternative sources and methods to produce energy is crucial (Kim et al 2019, Vuppaladadiyam et al 2019, Yasar et al 2001, Zhang et al 2019. One such alternative source stems from the utilisation of biomass to make products suited for energy applications.…”

Influence of microalgae on synergism during co-pyrolysis with organic waste biomass: A thermogravimetric and kinetic analysis

“…[1] Owing to facts such as depletion of fossil fuels, rises in greenhouse gases emissions, the research in the last few decades has been directed to identify alternative energy resources [2]. Biofuels generated from sources like biomass are considered to be ideal substitutes to traditional fossil-based fuels and are extensively studied in the recent past [3][4][5]. Additionally, legislation of biofuels, in many developed countries, as renewable fuel standard and renewable portfolio standard has been done to promote their early adoption [6].…”

“…Additionally, a sustainable and carbon neutral mode of biofuels production can be made possible when the microalgae cultivation units are integrated with powerplants/cement industries and wastewater treatment units [10]. In addition to microalgae based biofuel production, domestic waste biomass, which contain materials such as paper, plastic food waste, textile and wood materials, has been widely considered as potential resource for sustainable energy production J o u r n a l P r e -p r o o f and resource recovery [3]. China, which is the world most populated country, has produced ca.…”

Limiting factors for biogas production from cow manure: energo-environmental approach

“…However, because of environmental concerns, the world is shifting towards renewable energy resources (Afsharzade et al, 2016;Baena-Moreno et al, 2019;Eder & Mahlberg, 2018;Lyytimäki, 2018;Nethengwe, Uhunamure, & Tinarwo, 2018;Rosa et al, 2018;Vochozka, Maroušková, & Šuleř, 2018). Consequently, we have also been witnessing major technological advances in renewable energy systems (Baranyai, Mosavi, Vajda, & Varkonyi-Koczy, 2017;Imani, Zalzar, Mosavi, & Shamshirband, 2018;Moeini, Ahmadpour, Mosavi, motivation to move towards using various types of solid wastes for the purpose of energy production (Dabe, Prasad, Vaidya, & Purohit, 2019;Lino & Ismail, 2018;Tiwary, Spasova, & Williams, 2019;Vuppaladadiyam, Zhao, Memon, Soomro, & Wei, 2019a, 2019b.…”

“…There are several reasons for the significant lack of renewable energies, such as lack of public awareness about renewable energies, inexpensive fossil energy resources in Iran, a lack of a sense of environmental pollution threats and the high cost of renewable energies in Iran (Seyyed aram & Najafi, 2016). The literature includes a number of methods to address this issue (Dabe et al, 2019;Lino & Ismail, 2018;Tiwary et al, 2019;Vuppaladadiyam et al, 2019aVuppaladadiyam et al, , 2019b. One of the most efficient proposed methods is to switch to biogas production technology (BPT), which can provides a part of the energy needs as a clean energy resource.…”
