摘要

This work aims to integrate Environmental, Social, and Governance (ESG) principles into the using of coconut fiber residue for producing partially delignified cellulose nanofibrils (CNFs), providing significant benefits across all three dimensions of sustainability. A combination of alkaline treatment with mechanical refining using a colloidal mill, to our knowledge, has not yet been reported. This study explores the relationship between process parameters, the physicochemical and thermal properties of CNFs. Produced CNFs displayed FTIR spectra that indicate significant removal of lignin and hemicellulose content due to alkaline treatment. XRD data showed higher crystallinity, with a crystallinity index improvement from 42.91 to 65.98%, and thermal stability was enhanced, with carbonaceous residues ranging between 27 and 30%, as confirmed by TG analyses. The yield was 7.208%. The cost evaluation is also reported, based on applied methodological parameters and achieved yield. By leveraging coconut fiber residue within an ESG framework, companies can create environmentally friendly products, support social development, and adhere to strong governance principles.
