Endocarp residues remaining after coconut oil extraction from Acrocomia aculeate are traditionally used for combustion as fuel. As an alternative, we propose its conversion into biochar to substitute peat in planting substrates. To test the feasibility of this approach, untreated endocarp residues (particle size approx. 10 mm) and materials...

The aim of this study was to prepare a complex between the olive phenolic compounds, hydroxytyrosol (HT), 3,4-dihydroxyphenylglycol (DHPG) and their mixture, with the soluble and insoluble dietary fiber of apple cell wall. A strong interaction between phenols and the apple cell wall occurred during the drying phase and it was confirmed by...

Self-standing films of poly(ω-hydroxyl hexadecanoic acid) [poly(ω-OHC16)] have been prepared by noncatalyzed melt-polycondensation in air at 150, 175, and 200 °C. Poly(ω-OHC16)s obtained are characterized as polyesters by infrared spectroscopy (FT-IR) and solid state magic angle spinning 13C nuclear magnetic resonance (13C MAS-NMR)....

Hydrothermal carbonization and dry pyrolysis transform sewage sludge (SS) into nitrogen- (N) and phosphorus- (P) rich hydrochars (Hyd) and pyrochars (Py), respectively, which may act as slow-release fertilizers with carbon (C) sequestration potential. Whereas this has been mostly studied with short-term experiments, this study focused on the...

The application of biochar as an organic amendment in polluted soils can facilitate their recovery by reducing the availability of contaminants. In the present work, the effect of biochar application to acid soils contaminated by heavy metal spillage is studied to assess its effect on the quantity and composition of soil organic matter (SOM),...
