Special Issue Information

Dear Colleagues,

Today, with rapid economic development and the continuous growth of the world population, energy consumption is sharply increasing. However, fossil fuel resources still dominate the energy market, accounting for 87% of global energy consumption. In response to the climate crisis and environmental pollution, many countries have revised their energy schemes, in which process renewable energy plays an important role. In this context, energy production from renewable biomass is one of the most attentive topics and currently seems to be a potential alternative to replace fossil fuels and reduce hazardous gas emissions. Among the different forms of renewable energy, biomass has been considered a crucial resource that can provide a variety of energy needs, including generating electricity, fuelling vehicles, and providing heat. According to some estimations, biomass is considered the fourth largest energy source in the world after coal, petroleum, and natural gas, accounting for 14% of the world’s primary energy consumption. The main advantage of biomass, as the only renewable carbon source, over all other renewable resources, is the possibility to be converted into solid, liquid, and gaseous fuels through different conversion routes. Although the process of conversion of renewable biomass to energy production has many advantages, the process still fails at a commercial scale due to several challenges.

This Special Issue aims to publish recent advances in the basic research and technological development of renewable energy through the high-value utilization of different biomass feedstock, mainly focusing on biowaste. Additionally, it aims to provide a comprehensive and cutting-edge multi-disciplinary analysis of the issues related to selecting a suitable conversion method for different biomass feedstock and the associated problem of biomass conversion.

We look forward to receiving your contributions.

In this study, the primary paper-mill sludge characterized as containing 51% glucan was used to optimize the enzymatic saccharification process for the production of bioethanol using a Box–Behnken design (BBD). Polyethylene glycol 4000 (PEG-4000) surfactant-assisted enzymatic saccharification of dried primary sludge (DPS) showed a 12.8% improvement in saccharification efficiency. There was a statistically significant effect of solid enzyme loading and saccharification time on the enzymatic saccharification of DPS at a 95% confidence level (p < 0.05). The optimum levels of 10.4% w/w DPS solid loading, 2.03% enzyme loading (10 FPU g/DPS), and 1% (w/w DPS) PEG-4000 loading for a saccharification efficiency of 57.66% were validated experimentally and found to be non-significant with regard to the lack of fit with the predicted saccharification efficiency of 56.76%. Furthermore, Saccharomyces cerevisiae fermented the saccharified sugars into ethanol (9.35 g/L) with a sugar-to-ethanol conversion yield of 91.6% compared with the theoretical maximum. Therefore, DPS is a more suitable renewable biomass for determining the presence of fermentable sugar and for the production of ethanol. Full article

In recent years, the world has witnessed an enormous effort to find a replacement energy source that is more environmentally friendly and renewable. Face masks that contain plastics lead to another management problem as they are non-biodegradable. Thus, by turning agricultural waste with plastic waste as an additive into beneficial products like briquettes, a solid waste problem can be minimized. In this study, Imperata cylindrica and mango peel commonly found in Malaysia were anticipated to boost the properties of solid fuel briquettes. Thus, the characterization of Imperata cylindrica, mango peel, and face mask waste as raw materials for the production of solid fuel briquettes is discussed in this paper. Proximate and ultimate analyses as well as Fourier transform-infrared (FTIR) were conducted to obtain the properties of the raw materials. FTIR results showed that face mask waste contained a methyl type group (CH3), and both agricultural wastes contained an oxygen type group (C–O–H). Based on the proximate analysis, face mask waste, mango peel, and Imperata cylindrica had low moisture contents, where mango peel had the highest moisture content (5.2%) followed by Imperata cylindrica (<1%) and face mask waste (<1%). Imperata cylindrica had the highest volatile matter content (94.6%) and the lowest ash content (2.3%), while mango peel contained the highest fixed carbon value, which was 16.1%. From the analyses conducted, face mask waste had the highest calorific value (26.19 MJ/kg1). Face mask waste contained 63.6% carbon and 10% hydrogen. Meanwhile, Imperata cylindrica and mango peel contained 44% and 40% carbon and 6.15% and 6.95% hydrogen, respectively. The characteristics and properties of face mask waste, mango peel, and Imperata cylindrica are significant for the contribution of the optimal ratio of these materials to form solid fuel briquettes.

Global resource limits and increasing demand for non-fossil energy sources have expanded the research on alternative fuels. Among them, algal biomass is designated as a third-generation feedstock with promising opportunities and the capability to be utilized for energy production in the long term. The paper presents the potential for converting beach wrack containing macroalgal biomass into gaseous fuel as a sustainable option for energy production, simultaneously improving the organic waste management that the coastline is facing. Beach wrack collected in the northern Baltic Sea region was converted by gasification technology applicable for carbon-based feedstock thermal recovery, resulting in syngas production as the main product and by-product biochar. Proximate and ultimate analysis, trace and major element quantification, detection of calorific values for macroalgal biomass, and derived biochar and syngas analysis were carried out. A higher heating value for beach wrack was estimated to be relatively low, 5.38 MJ/kg as received (or 14.70 MJ/kg on dry basis), but produced syngas that contained enough high content of CH4 (42%). Due to macroalgal biomass specifics (e.g., high moisture content and sand admixture), an adjusted gasification process, i.e., the combination of thermochemical procedures, such as mild combustion and pyrolytic biomass conversion, might be a better choice for the greater economic value of biowaste valorization.
