“…On the other hand, Zannikos et al [ 17 ] investigated the combustion properties of various compositions of solid fuel briquettes derived from waste plastic of PET and sawdust. Similar work was conducted by Garrido et al [ 18 ], who produced fuel briquettes from sawdust and pelletized date palm trunk with plastic waste. From the literature, we can conclude that plastic waste-derived fuel briquettes exhibited low calorific values when compared to char briquettes made from biomass waste [ 19 , 20 , 21 , 22 ] (see Table 1 ).…”

Slow pyrolysis using a batch reactor at 450 °C was applied to the polypropylene (PP) powder derived from Coronavirus Disease 2019 (COVID-19) isolation gown waste to yield char briquettes, using sugar palm starch (SPS) and a manual hydraulic press. These studies are significant because of reductions in plastic waste from the preparation of barbecue coal due to environmental sustainability. The results presented here include the physical, morphological, thermal, combustion, and mechanical properties of char when reinforced with various percentages of SPS loadings (0, 10, 20, 30, and 40%), which act as a matrix/binder to produce char/sugar palm starch (C/SPS) composites. The physical and morphological characteristics of C/SPS composites were determined using Fourier transform infrared (FTIR) and field emission scanning electron microscopy (FESEM). On the other hand, the thermal and combustion properties of the C/SPS briquettes were studied via thermogravimetric and bomb calorimeter analysis. The results show that the compressive strength of the briquettes increased as the SPS loading increased, whereas the higher heating values (HHV) reduced. The findings indicate that C-80/SPS-20 briquettes presented excellent combustion characteristics (1,761,430 J/g) with satisfactory mechanical strength (1.463 MPa) in the compression test. Thus, C-80/SPS-20 briquettes are the most suitable composites for domestic and commercial uses.

“…Agro-wastes, which can be used for briquettes production are corn straw, leaves of various species, coconut husk, bagasse, sawdust, etc. (Tamilvanan, 2013;Garrido et al, 2017). The SMS biomass generated after mushroom harvesting and recovery of enzymes can be converted into highquality biofuel products by compacting into a highdensity product called briquettes -a source of green energy (Garrido et al, 2017).…”

Spent Mushroom Substrate (SMS) comprises sugarcane bagasse, coconut coir, chicken manure, and paddy straw; inoculated with and farmed for Agaricus bisporus. At present, the waste generation at a mushroom cultivation plant in Goa is 40 tons/day (15,000 tons annually). Valorization of this waste has been explored in terms of extracting lignocellulolytic enzymes and briquette production. SMS was screened for the presence of lignocellulolytic enzymes and then was used to make briquettes. The enzymes found in SMS were cellulase and laccase, which were further concentrated via tangential flow filtration (TFF). Enzyme activity for Cellulase increased by four-fold (from 255.34±1.30 U/mL increased to 1022.21±4.84 U/mL) and Laccase increased by three-fold (from 4.83±0.02 U/mL to 13.21±0.05 U/mL). The concentrated enzyme cocktail was used to decolorize congo red dye. After only eight hours of enzymatic treatment at pH 4.8 on congo red, approx. 40-49% decolorization was accomplished. The color removal was due to the presence of the laccase enzyme. After enzyme extraction, all the residual SMS was utilized to generate briquettes with an initial reduction in its moisture content from 50% to 10%. The resulting briquette gave a Gross Calorific Value of 4,143 Kcal/kg with 12.60% ash content. Thus, SMS proves to be a valuable source for recovering enzymes and a cost-effective material for briquette production rather than going into landfills.

“…Donato et al 10 state that charcoal produced for metallurgical purpose should have mechanical strength equal to or greater than 70 kgf.cm -2 . Other methods of pelletizing charcoal with thermoplastic binders or other amounts of these in the blend can improve the mechanical properties of briquette 11 .…”

Physicochemical Properties of a Solid Fuel from Biomass of Elephant Grass Charcoal (Pennisetum purpureum Schum.) and Recyclable PET and HDPE

In the search for new solid fuels that can mitigate emissions of greenhouse gases and reduce municipal solid waste, it is proposed to produce a solid fuel from elephant grass charcoal (EGC) and blend it with the following binding recyclable materials, polyethylene terephthalate (PET) and high-density polyethylene (HDPE) with the aim of increasing their mechanical strength. Immediate analysis results indicate that there was an increase in volatile material content from 21.18% to 28.02% and a reduction in fixed carbon from 65.00% to 58.40% with the addition of binding agents. The higher heating value of pure charcoal was 5924.16 kcal/kg and there was no significant alteration by adding HDPE, however, with the addition of PET, there was an average reduction of 4.82%. According to the elemental analysis of charcoal, there were no significant amounts of sulphur, but silicon and potassium oxides were predominantly composed followed by aluminium, titanium, magnesium and iron according to the analysis of ashes. The addition of thermoplastic binders allowed producing pellets and it was found that those produced by using HDPE are stronger than those produced with PET.
