Abstract

The composting of sludge from the ultra-processed food industry in piles was evaluated through physicochemical, phytotoxic and spectroscopic parameters. The piles presented thermophilic phase for approximately two weeks. After 90 days, the seed germination index (SGI) reached values 62.5% for Pile 1 and 87.5% for Pile 2. Spectroscopic analyses revealed the degradation of aliphatic/polysaccharide structures and the increase of oxygenated functional groups present in humic acids. The concentrations of metallic ions were below the maximum value allowed under current legislation. The composting process in piles was efficient to degrade sludge from the ultra-processed food industry associated with garden pruning or sawdust, resulting in mature composts.
