Guatemalan waste can be converted into electricity, fuels, and energy

Solid waste poses a major environmental and health risk in Guatemala, accumulating in streets, rivers, and landfills. However, this waste holds untapped energy potential, and the University of the Valley of Guatemala (UVG) is actively developing technologies to transform it into electricity, fuels, and thermal energy.

Guatemala's waste management system is a structural challenge. According to the Ministry of Environment and Natural Resources, about 46% of solid waste is organic, followed by plastics (14%), paper and cardboard (10%), and sanitary waste (9%). UVG's research, including waste composition analysis and technological mapping, aims to provide the data needed for informed national decisions on waste-to-energy solutions.

One promising initiative is a pilot plant at UVG producing biodiesel from used cooking oil. This project, involving students, researchers, and faculty, can generate 200 gallons of biodiesel daily. By partnering with restaurants and institutions for used oil collection, UVG not only recycles waste but also provides biodiesel for vehicles. This process significantly lowers carbon monoxide emissions, with studies showing a 25% blend of biodiesel with diesel offers maximum emission reduction.

The use of biodiesel has been proven not to damage vehicles or reduce performance, as demonstrated by a USDA-tested vehicle since 2011. This research highlights the feasibility of transforming Guatemala's waste problem into a sustainable energy resource and a driver for development.
