Crude oil spill incidents have emerged as a prominent source of environmental contamination, adversely affecting marine ecosystems. This paper undertakes a comprehensive examination of the efficiency of utilizing green surfactants followed by a solid biofoam material as a viable remedy to remove crude oil contamination from a simulated mangrove environment within the Bodo region of the Niger Delta, Nigeria. During the study, four distinct soil samples encompassing sand, mud, peat, and peat–mud were meticulously collected to simulate the prevailing conditions in Bodo. Subsequently, surfactants were introduced into contaminated matrices at similar concentration levels over a specific time frame under the same conditions as in Bodo. Afterwards, a lignin-based biofoam material was then created with the goal of advanced remediation improvement. The outcomes show positive potential, presenting an innovative path for researchers to explore further environmentally sustainable solutions for contaminated muddy soils. The findings from the investigation include the following: (1) the interfacial tension caused by the best-performing surfactants was reduced to a level of 10−1 mN/m, demonstrating that the mobilization of contaminants and extraction are efficient using the studied formulations, especially for sand and muddy samples, and (2) advanced biofoam remediation showed an oil absorption level of 40%, with only brine water existing in the contaminated oil.
