“…In recent years, the interest in the use of biomass as a sustainable substitute for fossil fuel replacement has intensified due to its envisaged role in reducing greenhouse gas emissions, especially carbon dioxide (CO 2 ). 1,2 Thus, the production of bioenergy (energy from biomass) extracted from the lignocellulosic residues presents an interesting niche for research and development.…”

This work aims to investigate the energy-related characteristics of apple bagasse, orange bagasse and cashew-apple bagasse to identify their potential as bioenergy feedstocks. For this, a detailed characterization was performed, including proximate analysis, ultimate analysis, atomic molar ratio, heating values, chemical composition, bulk density, bioenergy density, fuel-value-index (FVI), fossil fuel equivalence and potential CO 2 retention. Proximate composition revealed moisture, volatile matter, fixed carbon and ash contents in the range of 7.8-9.3%, 67.1-74.2%, 16.2-22.0% and 1.6-5.7%, respectively. Typical values for carbon (44.8-49.9 wt.%), hydrogen (5.5-6.6 wt.%) and oxygen (40.1-44.2 wt.%), with low sulfur (< 0.1 wt.%) and nitrogen (< 2.7 wt.%) contents were found. In regard to bulk density (237.7-554 kg m −3 ) and bioenergy density (3.93-10.1 GJ m −3 ), juice processing residues have substantial values when compared with well-known lignocellulosic residues. Recoverable energy potential from the juice processing residues varied from 15.24 to 17.03 MJ kg −1 . From FVI analysis, apple bagasse is expected to be more suitable for thermochemical processing. Orange bagasse, on the other hand, has the highest equivalent in fossil fuel volume. Consequently, its use as solid fuel may lead to a decrease in CO 2 emissions from reference fuels.

“…This study aims to evaluate the capabilities of biochar and Fe-coated biochar produced from corncob husk (CH) and sugarcane bagasse (SB) of Brazilian crops to remove As(III) from highly contaminated aquatic systems. These feedstocks can be readily available, particularly in countries like Brazil and China, which have big sugarcane and/or maize crops (Bueno et al, 2017;Moraes et al, 2012). In addition, the use of leftover biomass from maize (corncob husk) and sugarcane (bagasse) production would minimise the waste generation and impact of these crops on the environment (Manochio et al, 2017).…”

Water contamination of As is a big issue in many areas around the globe. Therefore, cheap and efficient techniques are essential facing traditional treatment methods. Then, biochars (BC) emerged recently as material that can be used for As removal. However, research about efficiency of BC produced from local feedstock is still needed. The purpose of this study is to assess the efficiency of BC produced from sugarcane bagasse (SB) together with corncob husk (CH) with and without Fe(III) (BC) modification to be used for removal of As(III) from waters. The BC and BC produced at different pyrolysis temperatures were characterised using FTIR and SEM/EDS. Adsorption capacities of BC and BC were evaluated via batch adsorption, desorption and column tests and their performance was compared with adsorption using activated carbon. The results showed that Fe modification improve substantially the As(III) adsorption in a way that both BC and BC removed from 85% to 99.9% from 1000 µg/L As(III) solutions. Both materials fitted well in Langmuir model and the maximum adsorption capacity was 20 mg/g for BC and 50 mg/g for BC. The adsorption kinetics of BC was fast (≤ 30 min) and it had a better performance than activated carbon. The column tests showed that the process is efficient even at high As(III) concentrations. The fast removal process and good removal results make the BC and BC attractive for in situ and commercial (filters) use, since time and efficiency are required in new technologies.
