Mexico City's Sustainable Initiatives Transforming Urban Mobility

Mexico City's Ministry of Environment (SEDEMA) underscored the pivotal role of biodiesel from the Central de Abasto (CEDA) plant in driving the city's energy transition. Biofuel is actively employed in the municipal tractor fleet and is slated for expansion into additional vehicles.

This strategic move aims to mitigate greenhouse gas emissions (GHG), with a particular focus on repurposing used cooking oil for biodiesel production. By harnessing energy from this waste, the initiative eliminates the need for improper disposal. Notably, improper disposal of used cooking oil in drains can clog pipes and contaminate vast amounts of water, with just one liter capable of polluting 40,000L of water.

The biodiesel plant at Central de Abasto boasts a daily production capacity of 1,350L. The biodiesel is blended with conventional diesel in proportions ranging from 5% to 20%. The fuel is currently used in 20 tractors situated at the Vivero San Luis Tlaxialtemalco, with plans to extend its application to tankers and trucks in the San Juan de Aragon Forest. Furthermore, two passenger buses and vehicles at the Vivero Nezahualcoyotl area will soon join the sustainable fleet.

Biodiesel production relies on 100% Mexican technology, developed by IPN, with an installed capacity capable of producing up to 2,700L/d. Since 2019, SEDEMA has collaborated with Central de Abasto and local administrations to promote proper used oil separation through the "My kitchen does not pollute" project. This initiative encourages individuals to contribute to the repurposing of used oil for soap and biodiesel production.

Between January 2021 and July 2023, a substantial 35,763L of biodiesel have been produced, and 7,720L supplied to Metrobús during the same period last year. Beyond its positive impact on urban mobility, the biodiesel initiative enhances air quality by reducing emissions from diesel combustion, facilitates wastewater treatment, mitigates flooding issues due to clogged drains, and contributes to improved public health through the reutilization of cooking oil.
