Pre-Treatment of Furniture Waste for Smokeless Charcoal Production

Abstract

The aim of this study was to assess the possibility of using furniture waste for smokeless fuel production using the pyrolysis process. Four types of wood-based wastes were used in the pyrolysis process: pine sawdust (PS), chipboard (CB), medium-density fiberboard (MDF), and oriented strand board (OSB). Additionally, the slow and fast types of pyrolysis were compared, where the heating rates were 15 °C/min and 100 °C/min, respectively. Chemical analyses of the raw materials and the pyrolysis product yields are presented. A significant calorific value rise was observed for the solid pyrolysis products (from approximately 17.5 MJ/kg for raw materials up to approximately 29 MJ/kg for slow pyrolysis products and 31 MJ/kg for fast pyrolysis products). A higher carbon content of char was observed in raw materials (from approximately 48% for raw materials up to approximately 75% for slow pyrolysis products and approximately 82% for fast pyrolysis products) than after the pyrolysis process. This work presents the possibility of utilizing waste furniture material that is mostly composed of wood, but is not commonly used as a substrate for conversion into low-emission fuel. The results prove that the proposed solution produced char characterized by the appropriate properties to be classified as smokeless coal.

Pyrolysis of Pruning Residues from Various Types of Orchards and Pretreatment for Energetic Use of Biochar

“…The lowest biochar yield, in turn, was produced during FP of PR performed at 600 °C (26.5 wt %), followed by AP (27.3 wt %) and PL (30.1 wt %). An analogous relation also was observed by other authors who described various wood biomasses such as birch wood [ 45 ], pine wood [ 46 ], or other wood-based materials [ 42 ].…”

“…The comparison of the above-described results with wooden biomass revealed the presence of a twofold process with overlapping stages [ 42 ]. The mass loss curve was more inclined in the main decomposition temperature range, and the values of dm/dt were higher.…”

Prospective Utilization of Wood Waste From Wood-based Industries in Ethiopia: Synthesis

“…Charis et al (2019) stated that between 2013 and 2017 there has been the production of modified 'smokeless' briquettes by using new densification techniques in Zimbabwe. According to (Kazimierski et al, 2020), furniture waste is a favorable material for smokeless fuel production through the densification process. The densification process reduces the moisture content of the wood waste, increases the bulk density, increases the calorific value of the fuel, and as well as improving the handling and transporting characteristics (Rominiyi et al, 2017).…”

Advanced Biofuels Based on Fischer–Tropsch Synthesis for Applications in Diesel Engines

“…These biofuels are produced from non-food and waste biomass such as forest biomass, including mining residues, agricultural waste (straw, hay, corn, rape, and other residues), energy plants (pterosaurs, sorghum, sorrel, etc. ), and biological waste from households, such as used frying oil, waste animal fat, and municipal waste [ 5 , 6 , 7 ]. Second-generation energy crops have a significantly higher transformation potential for biofuels than the first generation [ 8 ].…”
