Enhancing dissolved inorganic phosphorous capture by gypsum-incorporated biochar: Synergic performance and mechanisms.

Excess nutrients, such as phosphorus (P), in watersheds jeopardize water quality and trigger harmful algal blooms. Using phosphorus sorption material (PSM) to capture P from wastewater and agricultural runoff can help recover nutrients and prevent their water pollution. In this study, a novel designer biochar was generated by pyrolyzing woody biomass pretreated with a flue gas desulfurization gypsum.

Influence of biosolids and sewage effluent application on sitagliptin soil sorption.

Biosolids and sewage effluent application to agricultural fields is becoming a win-win practice as both an economical waste management strategy and a source of nutrients and organic matter for plant growth. However, these organic wastes contain a variety of trace chemicals of environmental concern such as pharmaceuticals and personal care products (PPCPs), which may pose a risk to agricultural fields and ecosystems. This work aims to investigate the sorption of sitagliptin on four agricultural soils, evaluate the effects of biosolids and sewage effluent application, and elucidate the main sorption mechanism of the pharmaceutical on soils.

Capture and recover dissolved phosphorous from aqueous solutions by a designer biochar: Mechanism and performance insights.

Excessive phosphorus (P) in marine and freshwater systems has been identified as a primary perpetrator for the harmful and nuisance algal blooms. In this study, a novel designer biochar was produced from sawdust biomass treated with lime sludge prior to pyrolysis. The adsorption of dissolved P on the designer biochar was comprehensively evaluated under different experimental conditions.

Effective delignification of lignocellulosic biomass by microwave assisted deep eutectic solvents.

To establish an environmentally friendly and cheaper method to delignify lignocellulosic biomass feedstocks, deep eutectic solvents (DESs) were investigated as a green alternatives to conventional solvents. Six different DESs were facilely prepared and used to delignify miscanthus and birchwood feedstocks, including monocarboxylic acid/choline chloride (ChCl), dicarboxylic acid/ChCl and polyalcohol/ChCl. The enhanced delignification efficiency was evaluated in relation to the nature of the hydrogen bond donors and acid strength of DES.

Photobioreactor cultivation strategies for microalgae and cyanobacteria.

The current burden on fossil-derived chemicals and fuels combined with the rapidly increasing global population has led to a crucial need to develop renewable and sustainable sources of chemicals and biofuels. Photoautotrophic microorganisms, including cyanobacteria and microalgae, have garnered a great deal of attention for their capability to produce these chemicals from carbon dioxide, mineralized water, and solar energy. While there have been substantial amounts of research directed at scaling-up production from these microorganisms, several factors have proven difficult to overcome, including high costs associated with cultivation, photobioreactor construction, and artificial lighting.
