Summary: In this study, a calcium modified biochar (CaBC800) was successfully fabricated to simultaneously remove phosphate and tetracycline from wastewater. The experimental results showed that CaBC800 had high adsorption capacities for both pollutants and the adsorption process followed pseudo-second-order kinetics and Langmuir adsorption isotherm. Chemical precipitation and ligand exchange were the main mechanisms for phosphate adsorption, while hydrogen bonding and pi-pi interactions were the main mechanisms for tetracycline adsorption.

Summary: A novel carbon nanotube-incorporated eucalyptus-derived activated carbon-based adsorbent was synthesized for the removal of dyes from wastewater. The maximum adsorption efficiency for methylene blue and eosin yellow was found to be 49.61 and 49.15 mg/g, respectively, with the pseudo second order model best describing the reaction kinetics involved in the process. This activated carbon adsorbent shows great promise for water decontamination applications.

Summary: The study demonstrates that torrefaction pretreatment can improve the efficiency of coffee grounds pyrolysis, decrease activation energy, and promote the generation of C=C. The optimal conditions are pyrolysis temperature > 600 degrees C and torrefaction temperature <= 270 degrees C. Different torrefaction temperatures have an impact on the composition ratio of bio-oils, with 200 and 250 degrees C potentially being more suitable for the torrefaction of coffee grounds.

Summary: Anaerobic mono- and co-digestion of coffee pulp, cattle manure, food waste, and dewatered sewage sludge were evaluated using biochemical methane potential tests. Mono-digestion of coffee pulp and food waste yielded higher methane yields compared to the co-digestion ratios examined, with no synergistic or antagonistic effects observed. Nine different kinetic models were compared, with cone and modified Gompertz models identified as best-fit for mono- and co-digestion of coffee pulp and cattle manure, and superimposed model for food waste and dewatered sewage sludge.
