Reducing CO2 emissions is urgently needed to slow down the impacts of climate change. capture using an amine solution has been developed and implemented at pilot commercial scales. However, scrubbing, in particular, produces a lot degraded solvents as waste energy intensive. Solid sorbents have used overcome these drawbacks. In this work, biomass-derived carbon materials were characterized. Advanced thermal chemical processes, i.e., hydrothermal pyrolysis applied produce from agrifood waste, such soybean okara. It was found that functional groups (-C=O -OH) appeared synthesized materials, implying generation surface oxygenated groups. Preliminary results showed activated carbons obtained with good yields relatively high areas, which may be adsorption solve emission problems.

Pyrolysis of residues enriched with carbon, such as in agroforestry or industrial activities, has been postulated an emerging technology to promote the production biofuels, contributing circular economy and minimizing waste. However, during pyrolysis processes a solid fraction residue is generated. This work aims study viability these chars develop porous carbonaceous materials that can be used for environmental applications. Diverse discharged by factory have activated KOH. Concretely, char came from olive stone, pine, acacia splinters, spent fuel, cellulose artificial casings. The changes textural, structural, composition characteristics after activation process were studied N2 adsorption-desorption isotherms, scanning electron microscopy, FTIR, elemental analysis, XPS. A great porosity was developed, SBET within 776–1186 m2 g−1 pore volume 0.37–0.59 cm3 70–90% micropores contribution. adsorption CO2, leading CO2 maximum uptakes 90–130 mg g−1. There good correlation between uptake microporosity oxygenated surface groups chars. Moreover, their ability contaminants aqueous solution also evaluated. there heavy metals, i.e., Cd, Cu, Ni, Pb, Zn, organic pollutants concern caffeine, diclofenac, acetaminophen.
