“…In our study, it was found that after 28 days of degradation, further prolongation of degradation time did not show signi cant impacts on the growth of strain PDBF01 and its degradation rate of PVA. It may mainly be due to the reduction of substrate after PVA degradation, limiting the access to carbon sources and energy, weakening the growth momentum of the strain [50,51].The growth of strain PDBF01 has reached a saturation state in such speci c environment. The changes may be related to an altered culture environment that is no longer suitable for the growth of the strain, as described previously [52].…”

Massive accumulation of plastics into environment has caused enormous pressure on the ecosystem. Efficient and environmentally friendly plastics degradation technologies have evolved into a global ecological challenge. Microbial degradation, as an eco-friendly plastic treatment technology, is confronted with a problem of low efficiency in its current application. Hence, it is crucial to discovery plastic biodegradable microorganisms and find the optimal conditions for their action. The aim of our study is to isolate plastic-biodegrading fungi and explore optimum conditions for their action. A strain isolate of Fusarium oxysporum was obtained from a degraded plastic handle through screening, separation, and purification and designated PDBF01 (CGMCC No.40272). In a screening assay of plastic polymers, PDBF01 only exhibited the degradability to polyvinyl alcohol (PVA), with no activity toward polyvinyl chloride, polypropylene, or polylactic acid. PVA degradation efficiency of PDBF01 was significantly affected by inoculum concentration, temperature, and degradation time. PDBF01 produced significant degradation of PVA under 28°C and 25% inoculum concentration. Moreover, the highest degradation rate reached 51.26% after 21 days. PVA degradation rate of PDBF01 was further increased to 58.83% by the addition of electrolytes (K+, Mg2+, Fe2+, and Ca2+). Our results suggested PDBF01 can be used as a potential and efficient PVA-degrading strain in practical applications.

“…Microorganisms have garnered attention for their potential in breaking down fossil hydrocarbon waste, including WMO. Nevertheless, this approach entails lengthy decomposition times and does not tap into the energy potential of WMO [13]. An alternative approach requires introducing WMO into the pyrolysis process of waste polyethylene (PE) and waste polypropylene (PP) to enhance the quality of the resulting liquid product [14], but this method remains relatively inefficient in harnessing the full energy potential of WMO.…”

Waste Motor Oil (WMO) is a hazardous waste material with the potential to contaminate water, soil, and the atmosphere. The management and engineering of WMO have become imperative in modern society for both resource utilization and environmental protection. Maximizing the energy content of WMO poses a significant challenge for researchers, to solve environmentally friendly solutions. Direct combustion of WMO often results in incomplete combustion and elevated CO emissions. Therefore, this research aims to optimize the harnessing of WMO's energy potential through a furnace equipped with steam injection. The steam is generated by utilizing the heat energy produced during the WMO heating process. Our study demonstrates that steam injection in the WMO furnace is an effective method for maximizing energy content while simultaneously reducing CO emissions.

“…Motor oil is mixture-based, synthesized from crude oil, and enriched with chemical additives for friction reduction. Waste motor oil (WMO) is full of sludge and burnt hydrocarbons and constitutes a hazardous waste (Pimda and Bunnag, 2015). Exhausted motor oil is a combination of several contaminants such as dirt particles, soot, and combustible products, among others.…”

“…Recent research has focused on the alternative to hydrocarbon bioremediation. For example, previous studies have shown that waste motor oil is degraded by Nostoc hatei TISTR 8405 (Pimda and Bunnag, 2015) and Pseudomona aeruginosa (Su et al, 2011); oilfield wastewater is biotreated using Rhodococcus cultures (Kuyukina et al, 2017). The biodegradation potential of crude petroleum has been assessed by hydrocarbonoclastic bacteria isolated from Soummam wadi sediments (Yalaoui-Guellal et al, 2020).…”
