Aug 14, 2013 · The composting of lignocellulosic oil palm empty fruit bunch (OPEFB) with continuous addition of palm oil mill (POME) anaerobic sludge which contained nutrients and indigenous microbes was studied.
Furthermore, compost enhances water retention capabilities and promotes healthy microbial activity in the soil, contributing to sustainable agriculture practices. Applications of Commercial Compost. The high-quality compost produced through commercial composting processes finds various applications across multiple industries: 1. Agriculture:
Apr 11, 2024 · EFB constitutes the most significant proportion of waste in palm oil production, comprising 44.21% cellulose, 16.68% hemicellulose, 35.51% lignin, and approximately 0.26% silica (Foong & Denny, 2022). This composition renders EFB resistant to decomposition.
Nov 10, 2018 · Incorporation of 5% green EG/AgNPs inhibitor into the steel reinforced concrete revealed enhanced corrosion resistance, where a protective thin barrier was developed over the steel reinforced surface. This improvement was attributed to the formation of extra calcium silicate hydrate (C-S-H) gel in the concrete and thereby blocked the concrete
