Increasing environmental awareness has boosted interest in sustainable alternatives for binding natural reinforcing fibers composites. Utilizing lignin, a biorenewable polymer byproduct from several industries, as component matrices can lead to the development of more eco-friendly and high-performance composite materials. This research work aimed investigate effect two types lignin (lignosulfonate soda lignin) on properties hemp fiber-reinforced polypropylene composites furniture applications. The were produced by thermoforming six overlapping layers nonwoven material. A 20% addition or lignosulfonate (relative mass) was incorporated between made 80% (PP). both resulted an increase tensile bending strength lignin-based composites, well decrease absorbed water percentage. Compared oriented strand board (OSB), exhibited better properties. Regarding used, than those containing lignin. Thermal analysis revealed that thermal degradation begins long before melting temperature polypropylene. early explains inferior compared with lignosulfonate.

The transition from fossil fuels to renewable energy (RE) sources is an essential step in mitigating climate change and ensuring environmental sustainability. However, large-scale deployment of renewables accompanied by new challenges, including the growing demand for rare-earth elements, need recycling end-of-life equipment, rising footprint digital tools—particularly artificial intelligence (AI) models. This systematic review, following Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) guidelines, explores how lightweight, distilled AI models can alleviate computational burdens while supporting critical applications systems. We examined empirical conceptual studies published between 2010 2024 that address energy, circular economy paradigm, model distillation low-energy techniques. Our findings indicate adopting significantly reduce consumption data processing, enhance grid optimization, support sustainable resource management across lifecycle infrastructures. review concludes highlighting opportunities challenges policymakers, researchers, industry stakeholders aiming integrate principles into RE strategies, emphasizing urgent collaborative solutions incentivized policies encourage low-footprint innovation.
