Abstract

The sustainable management of waste generated by human activities is now a global concern. The valorization of waste by pyrolysis is a recycling method aiming at obtaining a biochar which can contribute to improve the fertility of soils and to limit the use of chemical fertilizers. It is in this perspective that the present study aims to valorize cassava peelings into biochar. Slow pyrolysis was applied for biochar production using an artisanal oven at 400 °C and the obtained biochar was characterized. FTIR analysis revealed that cassava peelings biochar consists of hydrophilic surface functional groups (mainly -OH and -COOH). EDX analysis showed that the biochar is mainly composed of carbon (78.65%), oxygen (18.65%), phosphorus (0.26%), potassium (1.91%), calcium (0.30%), magnesium (0.13%), silicon (0.10%), and nitrogen (1.14%), was determined by Kjeldahl method. SEM micrographs revealed that the biochar has a rough and porous surface. The BET surface area and BJH average pore diameter of the biochar are 341.11 m2/g and 1.44 nm, respectively. X-ray diffraction showed that the biochar is amorphous and consists largely of calcite (CaCO3). C/N ratios of 68.51; O/C of 0.23 and H/Corg of 0.03 were also obtained. These results show that the biochar produced has acceptable qualities and can be used as a soil amendment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
