“…To address this global challenge, the use of potato peel as a valuable resource to produce value-added bioproducts has considerable potential [9] . Thus, several studies have investigated the feasibility for recovering phenolics compounds from potato peel by organic solvent extraction [10,11] or natural deep eutectic solvent [12] and glycoalkaloids from potato peel using electro-membrane extraction method [13] . In addition, the valorization of potato peel into bioenergy and biofuels might be another productive area of research due to the merits of thermochemical conversion including (1) fast reaction rate, (2) the abilities for processing of various types of feedstocks, and (3) the potential for producing other valuable bioproducts like biochar produced from gasification.…”

“…In addition to the bio. Furthermore, the lignocellulosic composition of biomass affects the liquid yield, as it has great potential for producing transportation fuel on a very large scale [57]. Biomass containing higher amounts of cellulose also increases bio-oil or liquid yields, such as esters, ethanol, aldehydes, acids, phenol, alcohols, and other organic compounds [15].…”

This study aims to evaluate the physicochemical properties of rubberwood sawdust (RWS) and sewage sludge (SS) for producing biofuel or liquid products via pyrolysis and co-pyrolysis. The chemical and thermal properties of both samples were observed to have superior bioenergy production capabilities. RWS and SS had significantly different physicochemical properties, such as particle-size distribution, bulk density, ultimate and proximate analysis, lignocellulose composition, thermal-degradation behaviour, and major and minor elements. The composition of extractives was found to only marginally affect the end product. Carbon and hydrogen content, the two main elements for biofuel enhancement, were found to correlate with the organic components of both RWS (48.49, 7.15 wt.%) and SS (32.29, 4.06 wt.%). SS had a higher elemental composition of iron, calcium, and potassium than RWS. Both samples had a higher heating value of 13.98 to 21.01 MJ/kg and a lower heating value of 11.65 to 17.66 MJ/kg, a lesser energy potential than that of fossil fuels. The findings from these blends are relatively moderate due to the related lignocellulosic potential composition. The novel contribution of this research was to optimize the use of local waste materials as a new raw material for biofuel production that could serve as a sustainable fuel source.

“…However, the researchers turned their attention to huge availability of wastes rich in carbon (e.g., plastics, agricultural) as raw materials for activated carbon synthesis, trying to solve two issues at the same time: waste disposal and CO 2 capture [20][21][22]. In this context, the sewage sludge resulting from wastewater treatment plants could be a promising candidate for CO 2 adsorbents obtaining and energy or fuel production through different processes, such as pyrolysis [8], gasification [23] or combustion [24].…”

Sewage Sludge Derived Materials for CO2 Adsorption

et al. 2021

The study tried to contribute to solving two serious environmental issues: CO2 reducing and sewage sludge disposal. Thus, sewage-sludge-derived materials were obtained in order to be evaluated for CO2 adsorption capacity. Therefore, the char resulted after the sewage sludge pyrolysis was subjected to oxidation and chemical activation processes by using different quantities of alkaline hydroxide. One of the obtained materials, activated with a lower quantity of alkaline hydroxide, was also treated with acid chloride. Further, the materials were structural and texturally characterized, and material treated with acid chloride was used for CO2 adsorption tests, due to high surface area and pore volume. The handmade system coupled to a gas chromatograph allowed the adsorption efficiency evaluation using different feed gases (rich and poor in CO2) by completed purge of pipe line and on-line check. Additionally, the adsorption capacity, separation efficiency, and CO2 recovery were calculated. Taking into account the values for adsorption capacity (separation efficiency and CO2 recovery), it can be concluded that the sewage sludge derived material could be a promising solution for CO2 reduction and waste disposal.
