The implementation of a circular economy for empty agrochemical containers in areas where agriculture is intensive and the use of agrochemicals is in large quantities, is necessary to reduce the impact on the environment and people's health. Training the primary producers of empty containers and agrochemical companies in the correct management of hazardous waste, as well as promoting the participation of the social and private sectors in activities of recovery and recycling of hazardous waste are some strategies aimed at avoiding the disposal end of empty agrochemical containers in the soil, bodies of water or incineration without controls, seeking in this way the recycling, co-processing or treatment of empty agrochemical containers.

The hazardous waste in Mexico is generated from a wide range of activities, such as automotive workshops, this type of generators produces spent oils, filters, paint packs and different types of solids impregnated with fats, oils and solvents, all these With dangerous characteristics, the mismanagement of hazardous waste leads to environmental and health risks in humans and wildlife, so they require storage, transport and final disposal in a safe manner. A study was carried out in the mechanical workshops of the city of Los Mochis, Sinaloa, with the purpose of analyzing the handling of hazardous waste, especially used oils and solids impregnated with fats and oils. As evaluation instruments, a survey and a checklist were applied based on the specifications indicated in the Mexican environmental legislation on waste. 43% of the workshops do not have a temporary warehouse, 39% are not registered with the authority as generators of hazardous waste, 43% generate more than 100 kg of hazardous waste per month and 19% of these waste are spent oils. It was concluded that not all workshops work under the guidelines of the Mexican environmental legislation on waste, for which reason a more exhaustive vigilance is recommended by the competent authorities in the matter.
