Environmental waste management in mechanical workshops: towards a culture of urban sustainability

The study examined the environmental impact generated by auto repair shops, focusing its analysis on the inadequate management of hazardous waste such as lubricating oils, batteries, and polluting filters. National and international background information was reviewed, which showed poor performance by auto repair shops in terms of waste management, in many cases without complying with current environmental regulations. Various studies concluded that waste was disposed of in the environment without prior treatment, seriously affecting water, air and soil. Structural causes were also identified, such as lack of information, limited budgets, absence of municipal permits and poor enforcement by the competent authorities. Alternative solutions were explored, such as the application of bioremediation techniques using microorganisms and the use of activated biochar, which proved effective in restoring contaminated soils. The theoretical framework included the Battelle-Columbus theory and fundamental concepts of ecology and environmental psychology, providing an understanding of how human perceptions and behaviours influence sustainability. The regulatory analysis demonstrated the existence of environmental laws but highlighted their limited application in practice. It was concluded that the environmental management of these establishments required not only sanctions and control but also a cultural and educational transformation that would promote collective sustainable behaviour.
