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
bacteria, antibiotic resistance genes, microbial commu-nity composition, and function succession in different dairy manure composts and provide useful information for further optimization of composting practices. Key words: dairy manure compost, antibiotic-resistant bacteria, antibiotic resistance genes, microbial community diversity INTRODUCTION
