Summary: Organic sticky contaminants pose a significant challenge in paper recycling, causing various issues in the paper machine. This study analyzed and characterized the nature of sticky contaminants in different wastepaper grades using screening, solvent extraction, and analytical techniques. The content of stickies varied among paper grades, with higher amounts found in curb side collection wastepaper. The major components of the sticky contaminants were identified as polyvinyl acetate polymers, styrene butadiene rubber, paraffin waxes, and polyamines. The findings provide insights into the nature and behavior of stickies, with the aim of developing efficient technologies for contamination removal in paper recycling.

Summary: The current energy crisis and waste management problems have led to the investigation of alternative solutions. This study explored the feasibility of pyrolysis of commonly used plastics as a way to recover energy and manage plastic waste. Results showed that pyrolysis of polyethylene terephthalate (PET), high- and low-density polyethylene (HDPE, LDPE), polypropylene (PP), and polystyrene (PS) resulted in flammable liquid products with high fuel conversion yields. The calorific values of these products were comparable to diesel and gasoline, making them potential fuel alternatives. Implementing this study could mitigate energy and environmental issues in developing countries and create entrepreneurship opportunities.

Summary: Seaweeds, primitive plants and macroalgae, typically grow in shallow water areas such as backwaters, estuaries, and seas. They attach to coral reefs, rocks, and other substrata. Researchers collected seaweeds from the Kanyakumari region and processed them to extract methanol using the Saccharification method. The highest yield of methanol (51.2%) was obtained with a substrate concentration of 15% and a time duration of approximately 48 hours. The study focused on producing methanol from a high concentration and choice of seaweed (Sargassum wightii).

Summary: Spent caustic discharges contribute to increased oil and grease content in refinery wastewater, leading to higher treatment costs; a case study on Sines refinery found that processing high kerosene cut acid crude oil may increase effluent management cost by up to 3 euro/ton of processed crude oil. Spent caustic O&G effluents typically consist of organic contaminants with low molecular weight, aromatic and polar arrangements like phenolic groups and naphthenic acids, highlighting the importance of identifying suitable technologies for treatment.

Summary: This study explored the pyrolysis behaviors and mechanisms of different monosaccharides, including arabinose, galactose, galacturonic acid, and glucuronic acid. The roles of structural differences in these monosaccharides were analyzed, and it was found that glucuronic acid undergoes a special C-C bond breaking reaction during pyrolysis. The findings provide a deep understanding of the pyrolysis chemistry of hemicellulose and the role of different branches.

Summary: The accurate prediction and assessment of soot emissions in internal combustion engines are crucial for the development of sustainable powertrains. This study presents a detailed quadrature-based method of moments (QMOM) soot model coupled with a state-of-the-art flow solver for the simulation of gasoline engines. The model accurately describes the entire cause-and-effect chain of soot formation, growth and oxidation. Experimental validation and engine cycle simulations are used to identify the root cause of observed soot formation hotspots.
