Researchers in Colombia have conducted a study on the microbiological characterization and potential alternatives for using sludge generated from service stations. The research study collected samples of sludge from different service stations in Colombia and performed microbiological analyses to evaluate the presence of bacterial and fungal populations.

The study found that the sludge samples contained high concentrations of bacteria and fungi, including potentially pathogenic species such as Pseudomonas aeruginosa and Aspergillus niger. This finding highlights the potential risks of using sludge from service stations due to its high microbiological content.

However, the study also explored the potential use of the sludge as a substrate for biogas production through anaerobic digestion. The results indicated that the sludge had a high potential for biogas production, with methane yields of up to 304 mL CH₄/g VS added. This finding presents an alternative option for safe and sustainable waste management.

In addition to biogas production, the study explored the possibility of using sludge as a soil amendment. The results showed that the sludge could be a soil amendment, positively affecting soil fertility and plant growth. This finding presents another alternative option for the safe and sustainable management of this waste.

This research provides valuable insights for developing policies and regulations to promote safe and sustainable sludge management from service stations. The study highlights the potential risks of using sludge from service stations due to its high microbiological content. It also presents alternative options for the safe and sustainable management of this waste. Biogas production and soil amendment are two potential alternatives that can be explored further for the safe and sustainable management of sludge from service stations.
