This article aims to present a critical review of the generation, physicochemical properties, and chemical composition of brewer's spent grains as a carbon-rich by-product of the brewing industry. The carbon-rich nature of the by-product makes it suitable for various valorisation options such as functional food, animal feed, bioenergy, bio-based chemicals, biomaterials, and carbon-based materials such as activated carbon and biochar. The review also assesses the technologies for industrial processing and fractionation of the material necessary to unlock the potential of the BSG. These include drying, milling, pretreatment, enzymatic hydrolysis, and fermentation. Environmental and sustainability assessment, such as the carbon footprint reduction potential of the material, is also discussed in the context of the overall impact of the material.

In the food and beverage industry, SFE is mainly used to extract pure and high-quality chemicals; to extract bioactive molecules; to extract the inherent taste of fruits, spices and herbs; for coffee decaffeination; and for the extraction of essential flavors. Pharmaceutically, SFE ensures the extraction of bioactive chemicals from medicinal plants, omega-3 fatty acids and antioxidants with minimal degradation and has a great role in the development of novel medications. The preservation of agricultural products by enzyme deactivation and microbial reduction is another promising application. It is considered one of the most advanced greener technologies as due to its minimal adverse effect on the environment and the ability to reuse solvents. SFE could be combined with chromatography, ultrasound, and microwave to make it more efficient and selective.

In decentralised farming systems, limited monitoring and process control increases the risk of uncontrolled emissions and environmental hazards. This study evaluates farm-scale carbon capture and utilisation (CCU) strategies within a circular and sustainable chemistry framework integrating emission mitigation, resource recovery, and environmental protection. A structured synthesis of peer-reviewed studies shows that membrane-based CO₂ recovery achieves 85–95% capture efficiency, biochar systems increase soil carbon storage by 0.3–0.8 C ha⁻¹ yr⁻¹ , algal utilisation produces 30–45 g m⁻² day⁻¹ biomass, and greenhouse CO₂ enrichment improves crop yields by 20–30%. Compared with conventional non-CCU agricultural operations, integrated systems reduce net emissions by approximately 15–40%, equivalent to 0.5–2.5 t CO₂e ha⁻¹ yr⁻¹ depending on technology configuration and system boundary. The study further highlights the importance of robust measurement, reporting, and verification (MRV) systems, predictive risk management, and IoT-enabled digital monitoring for ensuring process stability, leak detection, and environmental accountability. A conceptual smart environmental management framework that combines real-time sensing, digital dashboards, and risk-informed operational controls is proposed to support safer deployment and scalability of low-emission agricultural systems.

Considering their high surface area, surface functionalization potential, and superior adsorption capabilities, nanomaterials have been extensively studied for dye removal; yet, the existing research is still dispersed, primarily concentrating on isolated modeling techniques or experimental adsorption performance. For the advancement of predictive optimization and mechanistic assessment, there is a prominent research gap in the systematic integration of modern computational, machine learning, and molecular modeling techniques with nanomaterial-based dye removal. In addition to machine learning techniques like artificial neural networks, support vector machines, decision trees, gradient boosting, adaptive neuro-fuzzy inference systems, and hybrid optimization frameworks, response surface methodology is discussed.
