A Review on Turning Waste into Wealth: Valorization Sewage Sludge as a Resource for Sustainable Energy

Future Perspectives of Medical Pharmaceutical and Environmental Biotechnology, Год журнала: 2024, Номер 1(1), С. 31 - 38

Опубликована: Март 31, 2024

The renewable energy sector is experiencing rapid growth as researchers, economists, and decision-makers aim to meet multiple objectives. These include generating from more sustainable environmentally friendly sources, well addressing the increasing disparity between supply demand in a market where continues rise. It important seek balance that ensures ongoing economic industrial development while prioritizing environmental health. One promising solution this regard production of biofuel sewage sludge, which has calorific value 8,300 joules per gram. From an perspective, achieving reduction greenhouse gas emissions necessitates daily target 4.6´107 gigajoules by 2040. This review will cover knowledge about sludge form biomass how utilize raw materials various types biomasses. Special focus be given selected biofuels, including biodiesel, bioethanol, biogas, serve alternatives their fossil fuel or natural counterparts.

Sugar Fermentation by Non-conventional Hansenu-La Polymorpha Yeast to Co-produce Methanol, Ethanol and Butanol

Опубликована: Март 26, 2024

Hansenula polymorpha is a non-conventional, methylotrophic, and thermo-tolerant yeast well known for the industrial production of recombinant proteins. However, research to evaluate this potential sugar fermentation produce alcohols biofuel applications at an infant stage. For advancement, present work investigated wild type H. strain (DSM 70277) co-production methanol, ethanol, butanol using batch reactor performing experiments ideal temperature 40°C with pH 5.5 different sugars (fructose, glucose, xylose) as substrates. The maximum specific growth rates (h-1) were 0.59–3.02 fructose, 0.08–2.60 0.06–0.08 xylose. overall yields (g/g) methanol higher from fructose (0.132–0.226) than glucose (0.020–0.021) xylose (0.009–0.030). Ethanol yield (0.130–0.325) was more (0.054–0.167), (0.042–0.068). ranged 0.018–0.031 (fructose), 0.017 (glucose), 0.009–0.010 (xylose). Due methylotrophic nature polymorpha, shorter time (preferably 2 h) found suitable butanol.

Recent advancements and challenges in the lignocellulosic and algal biomass-based bioethanol production: a review

Biofuels, Год журнала: 2024, Номер unknown, С. 1 - 20

Опубликована: Дек. 4, 2024

The sustained increase in global energy needs and environmental impacts from greenhouse gases emitted by burning non-renewable fuels has led to a focus on developing renewable sources. Bioethanol can meet future demands of nations. Lignocellulosic feedstock algal biomass are considered effective sources substrates for converting fermentable sugars into ethanol. structural configuration lignin-based cellulosic is modified using integrated pretreatment technologies, including physiochemical biological methods. hydrolysis cellulose with cellulase enzymes consists adsorption the surface, disintegration polymers simple sugar compounds, desorption cellulase. Soybean straw fermented Thermoanaerobacterium aotearoense at 55 °C 15 g/L total provided 0.34 g/g ethanol yield. Rice hydrolyzed 30 °C, 74 h, pH 4.5 yielded 0.44 macroalgae species Ulva rigida solid-state fermentation Saccharomyces cerevisiae 37 5, 3 h 330 mg/g glucose. microalga Chlorella vulgaris 45 6, 48 amylases 3.8 Different processes reduced include submerged, solid-state, very high-gravity fermentation.
