Since 2017, Mexican scientists have been researching transforming prickly pear cactus into biogas.

According to AFP, scientists in Mexico have devised a way to convert prickly pear cactus into biogas. In Mexico, the striking, brilliant green cactus is widely grown for usage in beverages, medications, and shampoo.

In May 2017, a pilot operation was established in Milpa Alta's cactus market, which generates up to 200,000 tonnes of prickly pear cactus annually. Every day, up to 10 tonnes of this cactus becomes garbage on the market floor.

Mexican Green Energy Start-up Suema decided to create a biogas generator to convert trash into energy. According to the AFP, the generator will eventually be able to treat three to five tonnes of trash every day, resulting in 170m3 (45,000 gallons) of biogas and more than one tonne of compost.

This will generate 175-kilowatt hours of electricity, enough to run 9,600 low-energy light bulbs.

The Mexican government supported the $840,000 project. Mexico pledged in 2015 to cut emissions by 2050. In 2016, green energy accounted for 15.4% of the country's energy mix, with biogas accounting for barely 0.1%. significant potential in providing sustainable energy solutions for semi-arid areas, aligning with efforts towards bioeconomy and renewable energy development.
