Additives for anaerobic digestion (AD) can play a significant role in optimizing the process by increasing biogas production, stabilizing system, and improving digestate quality. The of additives largely boils down to, among others, enhancing direct interspecies electron transfer (DIET) between microbial communities, resulting improved syntrophic interactions, adsorption toxic substances that may inhibit activity, stability accelerating decomposition complex organic materials, thereby rate hydrolysis. Through aforementioned action, significantly affect AD performance. function these materials varies, from activity to maintaining optimal conditions protecting system inhibitors. choice should be carefully tailored specific needs digester maximize benefits ensure sustainability. In light considerations, this paper characterizes most commonly used their combinations based on comprehensive review recent scientific publications, including report results conducted studies. publication features chapters describe carbon-based conductive metal oxide nanomaterials, trace metal, biological additives, enzymes microorganisms. It concludes with summarising reports various discussing functional properties, as well advantages disadvantages. presented is substantive concise analysis latest knowledge process. application characterized great potential; hence, subject matter very current future-oriented.

In order to study the effect of cotton stalk particle size on humification, stalks different lengths (5 cm, 10 15 cm) were co-composted with pig manure for 49 days. The results showed that cm treatment (T2) maintained a high-temperature stage 8 days, and total organic carbon decreased by 60.0%. T2 highest cellulose (57.0%) hemicellulose (77.1%) degradation rate, lowest lignin accumulation (69.8%), humus content (34.94 g/kg), which was 88.1% higher than in initial stage. FTIR analysis revealed significant changes functional groups. aromatic C=C stretching vibration (1650 cm−1) group increased 79.8%, showing better aromatization degree other two Two-dimensional spectroscopy phenolic alcohol hydroxyl groups first involved followed polysaccharides, hemicellulose, lignin, structures, enhanced this material transformation pathway. Microbial diversity identified seven main phyla, among Planctomycetota Acidobacteria abundance, closely related cellulose, compounds.
