Summary Oil palm ( Elaeis guineensis ) is a major oil crop that significantly contributes to the Indonesia's and Malaysia's economic growth. However, processing for extraction generates substantial waste, such as kernel cake, palm‐pressed fibre, empty fruit bunches mill effluent, which pose noticeable environmental challenges. This review explores green techniques waste processing, include microwave‐assisted extraction, deep eutectic solvents, ultrasound‐assisted supercritical fluid enzyme‐assisted subcritical water extraction. The potential industry scaling, mechanisms, applications challenges of each technique used are discussed. Microwave‐assisted particularly promising large‐scale production, while solvents paired with show improve efficiency. also reveals sustainable alternative conventional by effectively recovering valuable compounds from reduced impact. Additionally, diverse bioactive (vitamin E, phytosterols, phenolics, polyphenols flavonoids) extracted in food, pharmaceutical, cosmetic other industries presented. Valuable components cellulose, dietary fibres peptides derived can be applied food coatings, high‐protein products drug delivery systems. Biosorbents, biofuels biodegradable would provide benefits. Future research should focus on optimising industrial use promote responsible production circular management foster health safety.

Brewer's spent grains (BSG) offer valuable opportunities for valorization beyond its conventional use as animal feed. Among components, lignin-a natural polymer with inherent antioxidant properties-holds significant industrial potential. This work investigates the of microwave-assisted extraction combined acidic deep eutectic solvents (NaDESs) efficient lignin recovery, evaluating three different NaDES formulations. The results indicate that choline chloride-lactic acid (ChCl-LA), a superior thermal stability confirmed via thermogravimetric analysis (TGA), is an ideal solvent at 150 °C and 15 min, achieving balance high yield quality. ChCl-LA also demonstrated good solubility cell disruption capabilities, while microwaves significantly reduced processing time severity. Under optimal conditions, i.e., °C, in presence NaDES, extracted achieved purity up to 79% IC50 (inhibitory concentration 50%) approximately 0.022 mg/L, indicating relatively strong activity. Fourier transform infrared (FTIR) 2D-HSQC NMR (heteronuclear single quantum coherence nuclear magnetic resonance) spectroscopy successful isolation preservation structural integrity. study highlights potential BSG lignocellulosic resource underscores effectiveness NaDESs microwave recovery.
