“…Batch experimentations were performed using 250 mL bottles with 200 mL working volume and 37 °C water path. Methane-rich biogas was obtained by connecting the gas outlet of each digester to an alkaline solution (0.5 M NaOH) [18]. An inverted 50-mL measuring cylinder was used to quantify the biogas volume by water displacement.…”

“…Hence, a portion of terephthalic acid could be eliminated by adsorption onto the anaerobic sludge. Additional smaller peaks between 1545 and 1440 1/ cm were bonded into two strong peaks at 1631 and 1413 1/ cm after pyrolysis, probably because multiple oxides combined with the adjacent carbon elements to form a single carbon-oxygen bond [18]. Other peaks at 1120 and 1051 1/ cm revealed the presence of Si-O stretching and siloxanes.…”

“…Sludge pyrolysis was conducted in a muffle furnace (Linn High Therm) at 500 °C (rate of 12 °C/min), where an autoclave was used to maintain an oxygen-free atmosphere. The solid samples (sludge and biochar) were characterized following the procedures reported in our previous research [18]. For instance, a scanning electron microscope (JCM-6000PLUS NeoScope Benchtop SEM, Japan) was used to determine the surface morphologies of the AS and AS-BC samples.…”

This study investigates the utilization of petrochemical and domestic wastewater (PCW and DW) for dual biogas and biochar production, focusing on the economic and sustainable development criteria. Biogas yield by anaerobic co-digestion of a 0:1 (PCW:DW) feed was 306.4±11.8 mL per g chemical oxygen demand (COD) removed, which dropped by 12.7% with changing PCW:DW to 1:0. The results indicated that increasing the DW fraction in the feed encouraged the conversion of COD into more biogas and sludge amounts. The anaerobic sludge was subjected to pyrolysis to generate biochar with a yield of 0.6 g/g dry sludge. The delivered biochar showed appropriate surface morphology, elemental composition, physical properties, and surface functional groups, as demonstrated by SEM/EDX, XRD, and FTIR characterizations. The COD mass balance estimation of the anaerobic digestion system, with biochar yield, was used to determine the economic feasibility of treating 30 m3/day of wastewater. The 1:0 (PCW:DW) condition provided the most feasible scenario, with profits of 3340, 192, and 2819 USD/year for energy income, biochar selling, and pollution reduction, respectively. This economic benefit was equivalent to a payback period of 5.38 years. The fulfillment of multiple sustainable development goals (SDGs) related to clean and renewable energy production, human health protection, and economic growth was highlighted. Graphical abstract

The impetus to predicting future biomass consumption focuses on sustainable energy, which concerns the non-renewable nature of fossil fuels and the environmental challenges associated with fossil fuel burning. However, the production of rice residue in the form of rice husk (RH) and rice straw (RS) has brought an array of benefits, including its utilization as biofuel to augment or replace fossil fuel. Rice residue characterization, valorization, and techno-economic analysis require a comprehensive review to maximize its inherent energy conversion potential. Therefore, the focus of this review is on the assessment of rice residue characterization, valorization approaches, pre-treatment limitations, and techno–economic analyses that yield a better biofuel to adapt to current and future energy demand. The pre-treatment methods are also discussed through torrefaction, briquetting, pelletization and hydrothermal carbonization. The review also covers the limitations of rice residue utilization, as well as the phase structure of thermochemical and biochemical processes. The paper concludes that rice residue is a preferable sustainable biomass option for both economic and environmental growth.

Biomass is currently the main energy source in Nigeria, but it is being used and managed unsustainably, resulting in significant health and environmental risks. To support Nigeria's transition to an affordable, reliable, and low‐emission future, there is a need to shift from traditional biomass use to modern bioenergy applications. The research reviews the existing knowledge on themes relevant to developing sustainable modern bioenergy for Nigeria in the context of agri‐residues. It synthesizes the key findings on the themes from 161 scientific literature published between 2010 and 2021 on Nigeria and Sub‐Saharan Africa. The findings show that most literature focused on agri‐residues potentially available in large amounts but highly disaggregated, such as cassava and palm residues. Furthermore, the literature highlighted the importance of understanding agri‐residue aggregation, technological, economic, socio‐economic, governance framework of bioenergy, and the interactions with other sectors to unlock the full potential of modern bioenergy. While research acknowledged that bioenergy could enhance energy security, economic growth, and social co‐benefits, there has been less focus on the benefits of novel bioenergy solutions co‐created by relevant stakeholder groups in Nigeria. Involving relevant stakeholders in developing novel bioenergy solutions would address the missing link between resource assessment, appropriate technology deployment, and end‐user demand. It would also enhance the analysis of the bioenergy market and nonmarket benefits and ensure that bioenergy solutions in Nigeria are aligned with community needs and foster inclusivity.This article is categorized under: Sustainable Energy > Bioenergy Policy and Economics > Governance and Regulation
