Impact of innovative nanoadditives on biodigesters microbiome.

Nanoparticles (NPs) supplementation to biodigesters improves the digestibility of biowaste and the generation of biogas. This study investigates the impact of innovative nanoadditives on the microbiome of biodigesters. Fresh cow manure was anaerobically incubated in a water bath under mesophilic conditions for 30 days.

Innovative nanocomposite formulations for enhancing biogas and biofertilizers production from anaerobic digestion of organic waste.

Herein, the design of nanocomposite (NC) formulations that consist of metal enzyme cofactors, highly conductive carbon materials, DIET activators, to boost AD biogas production from anaerobically incubated cattle manure are investigated and discussed. Three different NC formulations were designed and synthesized: zinc ferrite (ZnFe), ZnFe with 10% carbon nanotubes (ZFCNTs), and zinc ferrite with 10% C76 fullerene (ZFC76). The structure and morphology of the nano-additives were investigated via x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive x-ray (EDX), and transmission electron microscopy (TEM).
