“…This ban will lead to saturated markets and price decreases, which will greatly An oxidative environment has different impacts on the decomposition of plastic materials. Pyrolysis without oxidation seems to be much simpler and easier to manage than oxidative pyrolysis, and elimination of the presence of oxygen is very important not only considering the quality of the resulting pyrolysis products, but also considering the simplicity of the operation of the pyrolysis equipment [15,16].…”

“…Thus, to advance the processing of municipal waste materials containing plastic, there is a need to increase the understanding of the thermal transformation process of plastic waste materials. This knowledge is especially valuable considering the need to develop pyrolysis/gasification technologies [14][15][16].…”

For decades, significant work has been conducted regarding plastic waste by dealing with rejected materials in waste masses through their accumulation, sorting and recycling. Important political and technical challenges are involved, especially with respect to landfilled waste. Plastic is popular and, notwithstanding decrease policies, it will remain a material widely used in most economic sectors. However, questions of plastic waste recycling in the contemporary world cannot be solved without knowing the material, which can be achieved by careful sampling, analysis and quantification. Plastic is heterogeneous, but usually all plastic waste is jointly handled for recycling and incineration. Separation before processing waste through the analytical approach must be applied. Modern landfill mining and site clean-up projects in contemporary waste management systems require comprehensive material studies ranging from the macro-characterization of waste masses to a more detailed analysis of hazardous constituents and properties from an energy calorific standpoint—where, among other methods, thermogravimetric research coupled with life cycle assessment (LCA) and economic assessment is highly welcomed.

“…The degradation of the major biomass material occurs between 200 and 400°C with a T p ranging from 355 to 370°C ( Chen et al, 2015 ; Cozzani et al, 1997 ; Sørum et al, 2001 ). The decomposition of lignocellulosic components usually consists of two stages: the first stage is attributed to the degradation of hemicellulose (200–350°C), cellulose (250–400°C), and partial decomposition of lignin (200–400°C); and the second stage is attributed to the degradation of the remaining lignin and charring of leftover (400–800°C) ( Boumanchar et al, 2017 ; Chhabra et al., 2019 ; Heikkinen et al, 2004 ; Porshnov et al., 2018 ; Skreiberg et al, 2011 ). In biomass mixtures, the DTG shoulder of hemicellulose might seem as a pronounced shoulder of cellulose rather than as a well-defined peak due to their similar decomposition ranges resulting in partial overlap ( Bosmans et al., 2014 ; Grønli et al, 2002 ).…”

Characterisation and composition identification of waste-derived fuels obtained from municipal solid waste using thermogravimetry: A review

et al. 2020

Thermogravimetric analysis (TGA) is the most widespread thermal analytical technique applied to waste materials. By way of critical review, we establish a theoretical framework for the use of TGA under non-isothermal conditions for compositional analysis of waste-derived fuels from municipal solid waste (MSW) (solid recovered fuel (SRF), or refuse-derived fuel (RDF)). Thermal behaviour of SRF/RDF is described as a complex mixture of several components at multiple levels (including an assembly of prevalent waste items, materials, and chemical compounds); and, operating conditions applied to TGA experiments of SRF/RDF are summarised. SRF/RDF mainly contains cellulose, hemicellulose, lignin, polyethylene, polypropylene, and polyethylene terephthalate. Polyvinyl chloride is also used in simulated samples, for its high chlorine content. We discuss the main limitations for TGA-based compositional analysis of SRF/RDF, due to inherently heterogeneous composition of MSW at multiple levels, overlapping degradation areas, and potential interaction effects among waste components and cross-contamination. Optimal generic TGA settings are highlighted (inert atmosphere and low heating rate (⩽10°C), sufficient temperature range for material degradation (⩾750°C), and representative amount of test portion). There is high potential to develop TGA-based composition identification and wider quality assurance and control methods using advanced thermo-analytical techniques (e.g. TGA with evolved gas analysis), coupled with statistical data analytics.

“…Figure 2 illustrates the compositions of municipal solid waste. Hence, the refuse-derived fuel fraction in municipal solid waste can be potentially used as another source of energy since it contains around 18 MJ/kg of calorific value which is comparable with soon-to be-depleted fossil fuel in less than 50 years from now (Porshnov et al 2018 ; Shahbaz et al 2016 ). Utilization of refuse-derived fuel as one of the energy sources is also well-aligned with the 7th sustainable development goal: affordable and clean energy (Dada and Mbohwa 2018 ).…”

Gasification of refuse-derived fuel from municipal solid waste for energy production: a review

et al. 2021

Dwindling fossil fuels and improper waste management are major challenges in the context of increasing population and industrialization, calling for new waste-to-energy sources. For instance, refuse-derived fuels can be produced from transformation of municipal solid waste, which is forecasted to reach 2.6 billion metric tonnes in 2030. Gasification is a thermalinduced chemical reaction that produces gaseous fuel such as hydrogen and syngas. Here, we review refuse-derived fuel gasification with focus on practices in various countries, recent progress in gasification, gasification modelling and economic analysis. We found that some countries that replace coal by refuse-derived fuel reduce CO 2 emission by 40%, and decrease the amount municipal solid waste being sent to landfill by more than 50%. The production cost of energy via refuse-derived fuel gasification is estimated at 0.05 USD/kWh. Co-gasification by using two feedstocks appears more beneficial over conventional gasification in terms of minimum tar formation and improved process efficiency.
