Summary: This study investigated the effect of substrate-inoculum ratio and fly ash concentration on the anaerobic digestion of winery wastewater. The results showed that a substrate-inoculum ratio of 0.50 g soluble COD/g VSS was the most effective. Among the tested fly ash concentrations, adding 100 mg/L improved methane production by 79%, while 150 mg/L inhibited methane production. Additionally, it was found that fly ash had a similar effect to a system with Fe-EDTA, indicating the bioavailability of Fe in the fly ash.

Summary: The study investigated the biochemical methane potential, biodegradability, and kinetic parameters of goat manure at different inoculum to substrate ratios. Results showed that the biomethane yield was similar among all ISRs and significantly higher than the control group. The biodegradability of goat manure was consistent across different ISRs, with 90% of the yield observed within 31 to 32 days.

Summary: The study found that when digesting cork boiling wastewater (CBW), the biomethane potential is very low for Ino/CBW ratios of 1:1 and 2:1 compared to other organic substrates using digested sludge as inoculum; however, co-digestion with cow manure showed better biomethane yields.

Summary: Phosphorylated cellulose nanocrystals (P-CNCs) are derivatives of cellulose nanocrystals (CNCs) that have garnered attention in various industries. A new eco-efficient process combining pre-phosphorylation with mechanical fibrillation was developed for the production of P-CNCs. This process not only improved the quality of P-CNCs, but also showed better environmental and economic performance compared to existing production processes.

Summary: The MCC-magnesium hydroxide composite adsorbent prepared by reacting MCC, magnesium sulfate hexahydrate, and trisodium citrate in an ammonia bath can efficiently adsorb and remove Co(II) ions, with optimal process parameters including an MCC-MH dosage of 2.5 mg/mL, a contact reaction equilibrium time of 50 min, a Co(II) solution pH of 6.0-8.0, an initial Co(II) concentration of 300 mg/L, and a temperature of 303 K. The removal rate of Co(II) solution by MCC-MH was as high as 97.67%, and the maximum adsorption capacity reached 153.84 mg/g.

Summary: This study demonstrates that high-COD/TOC produced water can be effectively removed with appropriate microbial inoculation, leading to energy recovery in the form of methane. Chemical analyses show that ethylacetate-extractable compounds in produced water are more amenable to biodegradation, while compounds added during drilling and completion significantly contribute to COD and anaerobic degradability.

Summary: Dyes and heavy metals are key pollutants that pose significant threats to human health and the environment. Conventional methods for treating contaminated water are costly, energy-intensive, and produce hazardous waste. Therefore, there is a need for cost-effective, efficient, and environmentally friendly processes for wastewater treatment. The use of cellulosic materials, such as cellulose and its derivatives, as adsorbents in water purification has gained attention due to their clean, sustainable, and effective characteristics in removing heavy metals and dyes. This review explores the application of cellulose-based substances in water purification, highlighting their potential, challenges, and future prospects.

Summary: The aim of this study was to use wastewater from the Arenga starch industry (WWAS) for the production of bacterial cellulose (BC) and cellulose acetate (CA). BC was produced through fermentation, while CA was produced through acetylation. The optimal conditions for BC production were determined to be a sucrose addition of 200 g/L, an initial medium pH of 4.5, and a cultivation time of 14 days. Acetylation of BC with a BC-acetic anhydride ratio of 1:3 resulted in CA suitable as a biofilm raw material with desired properties.

Summary: This study evaluated the biohydrogen potential of three Opuntia varieties and found that the hydrogen production is influenced by the inoculum-to-substrate ratio. Additionally, the use of methanol extracted residual biomass resulted in decreased hydrogen production. The study suggests further exploration of the use of Opuntia species for hydrogen production.
