“…At the end of the optimization process, the most efficient sewage sludge-based sorbent for the carbon dioxide separation, with an uptake of 102.5 mg/g, was produced in the following conditions: A similar adsorption capacity result was obtained from other studies considering other starting biomass. Recently, the wood ash from the biomass combustion was adopted for the gas cleaning [46], and there is the possibility to use such ashes for the CO 2 removal for the biomethane production [47]. Juarez et al (2018) developed a study wherein the fly ash from incinerated waste was adopted for CO 2 removal; the uptake ranged from 35 to 135 kg/t dry ash [46].…”

Anaerobically digested sewage sludges were used as feedstock in the production of activated carbons through physical activation. These char samples were experimentally tested as adsorbents for the removal of CO2 from a simulated biogas mixture. The CO2 concentration level allowed in biomethane was fixed from the European Standards EN 16723-1 and EN 16723-2. The char yield and the subsequent adsorption capacity values were studied, considering the operating parameters of the process. A physical activation process was considered with the following parameters: the temperature, the dwell time, the activating agent, the heating rate, the flow rate, and the method. Among the adsorption tests, the activating temperature and the agent employed affected the CO2 removal. The maximum adsorption capacity was achieved with nitrogen as an activating agent at 600 °C, with 2 h of dwell time (102.5 mg/g).

Abstract:The coupling of fuel cell technology with wastewater treatment plants (WWTPs) is within the sustainable development imperative for the integration of energy production purposes and recovery of materials, even if research is still under development in this field. The anaerobic digestion process can be used for fuel cell feeding, only if trace contaminants are removed continuously. The most harmful and frequent contaminant is H 2 S. This article shows the results of H 2 S adsorption on activated carbon fixed-beds (dry process), since it is one of the best solutions from both the complexity and costs perspectives. Inside the wide range of commercial activated carbons, a specific commercial carbon has been used in test campaigns, since it is also used in the Società Metropolitana Acque Torino (SMAT) real plant. Thermal regeneration of spent carbons was exploited, using different conditions of temperature, treatment time and atmosphere, since it is a better cost-effective and environmentally sound option than immediate carbon disposal after adsorption. Regeneration with CO 2 showed the best regeneration ratio values. In particular, the best conditions achieved were 300 • C and 75 min of thermal treatment time, with a regeneration ratio of 30%.

“…fossil fuels), the greenhouse gas emissions can be lower when woods are used [18], while some industries, such as wine production, can become more profitable by using their own residual biomass as a fuel [95]. It should be noted that, in the spirit of the circular economy, that the residual char/ash left after combustion can also have further use as catalysts/filters/scrubbers [96][97][98].…”

There is a growing interest in the utilisation of biomass for a range of applications. Coupled with 22 this is the appeal of improving the circular economy and as such, there is a focus on reusing, 23 recycling and upcycling of many materials, including biomass. This has been driven by society 24 in terms of demand for more sustainable energy and products, but also by a paradigm shift in 25 attitudes of the population to reduce their personal carbon footprint. Herein we have selected a 26 number of types of biomass (woody, herbaceous, etc.) and surveyed the ways in which they are 27 utilised. We have done this in combination with assessing some kinetic modelling approaches 28 which been reported for the evaluation of different processes for the recycling, reuse and 29 upcycling of biomass. 30
