Genomic analysis identified multiple orthologous gene clusters associated with hydrocarbon degradation, encompassing pathways such as <em>alkB</em>, <em>cyp</em> and <em>nah</em>. <em>Rhodococcus</em> sp. strain 1Y exhibited the highest number of these hydrocarbon-degradation gene clusters, highlighting its robust genetic potential and versatility in metabolizing diverse hydrocarbons. Secondary metabolite analysis identified stress-related biosynthetic pathways, including ectoine and siderophore production, supporting hydrocarbon solubilization and enzymatic activity. In a medium containing a mixture of phenanthrene and hexadecane (50 mg/L each) as the sole source of carbon, the consortium demonstrated rapid hydrocarbon degradation, with nearly complete degradation of hexadecane (reduced to 2.76 %) and partial degradation of phenanthrene (reduced to 36.56 %) by Day 12. Transcriptomic profiling across time points revealed dynamic shifts in gene expression, with 502 differentially expressed genes between Day 3 and Day 12, of which 487 were downregulated, enriched in pathways associated with xenobiotics biodegradation, lipid metabolism, and membrane transport.

State-of-the-art is to incinerate sewage sludge, which offers the benefits of volume reduction and the destruction of toxins, pathogens as well as the potential for recovery of the critical resource phosphorus from the generated ash. The latter is becoming increasingly important, particularly due to emerging regulations within the EU. Gasification as a thermal treatment method is also gaining traction as a suitable approach. The thermochemical process offers the same benefits as incineration but additionally produces gas (synthesis gas), a versatile fuel for energy generation and a precursor for the chemical industry.

This review provides a comprehensive overview of legislation related to sewage sludge management and feedstock characteristics, including ash chemistry.

The structural and physicochemical properties of M(F)/GO were characterized using field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), and other characterization techniques.
