BIOMETRANS project seeks to promote the recovery of dry and wet biomass waste generated in the Ibero-American Region through the production of biomethane and promote its use as a transport biofuel. Innovative processes will be designed to organize the logistics of biomass collection and the adequacy of the same for its treatment by anaerobic digestion. In this sense, different biomass pre-treatment technologies will be investigated to promote their biodegradability, the evolution of the anaerobic digestion process will be compared in one or two phases, and different biogas refining technologies will be investigated. Also, a biomethane commercialization model will be carried out in the region, assessing its potential environmental, social and economic impact, and the model of exclusively using biofuels in transport vehicles (biomethane and biodiesel mixture) will be considered.

The result will be a process to produce biomethane from residual biomass, optimized in an integral way (including the stage of collection of raw material, its processing and commercialization of products), adapted to the conditions of the participating countries and easily transferable, which will allow promote the use of biofuels in the region.

A total of 24 researchers from Spain, Peru, Mexico, Uruguay and Colombia will work for two years on this idea.

The CARTIF team (project coordinator) has developed its own biogas cleaning technology (double curtain scrubber) and is currently collaborating with a research team in India in the development of a membrane contactor with which expects to obtain biomethane with99% CH4.

For its part, Toro Equipment is one of the leading European companies specialized in the design and manufacture of equipment for the treatment of industrial and urban wastewater, process water, water reuse and treatment of sludge and other organic waste.

In Peru, the Catholic University of Santa María, has been working since 2004 in the production of biogas from organic waste, mostly agricultural.

In Mexico, CIATEJ’s participating research group is currently evaluating different biomass pre-treatments to maximize the production of biogas from tequila vinasses and agave bagasse hydrolysates, as well as the evaluation of biohydrogen production from these substrates. The Mexican companies Enfriadora Jalisciense and Translíquidos Serra, contribute the residual biomass with which to feed their own digester, and a fleet of trucks to carry out the tests with the biomethane generated in the project.

In Uruguay, the Renewable Energy Area of the Polo Tecnológico de Pando Institute has been working for 25 years in the production and characterization of carbonaceous materials and in the study of pyrolysis and biomass combustion processes.

In Colombia, the University of Santander has been present for years in the generation of knowledge about processes for the use of biomass.

In Guatemala, the Ingenio La Union has a fleet of transport trucks, which will be tested with biomethane.
