In fact, it is estimated thatthe installed equipment has avoided the emission of 9,000 tons of CO2 by the reduction of methane generated by the farm itself, and by the consumption of fossil fuels for energy production, which has been replaced by that provided by thebiodigesters devised by Joaquín Víquez.
His family roots, linked to the field, his studies as an agronomist and his later experience in agricultural operations, led him to create the Viogaz company in 2009 and to give shape to the idea that was in his head after seeing how the farms continued to treat excrement of livestock in a polluting and inefficient way, a luxury difficult to assume for small producers who, precisely, need to fine-tune their productivity to survive.
This is how their biodigester was born, which has beenrecognized by the MIT Technology Review because, that a producer incorporates this technology, it translates into “better use of agricultural residues, improving the productivity of developing rural areas ", considers Mark Hoffmann, member of the jury of Innovators under 35 years of Central America 2016, in which Joaquín Víquez was awarded.
This solution for the management of manure contains the costs of the farms, is designed to be especially durable and is focused on small and medium-sized farmers, who can replace a good part of the energy they used for that obtained from biogas.
The company offers farmers advisory and training services, as well as two biodigester options. The first, the Viogaz biodigesters, withup to twenty models available from 2 to 120 cubic meters of capacity liquid, so that each farm finds the one that suits its needs. The invention, created with a PVC geomembrane, has a useful life of 10 years.
The second possibility is theViogaz covered lagoons, preferable for a liquid capacity above 360 cubic meters, and suitable for those farms that have lagoons that, with this alternative, are covered at the bottom and at the top with a polyethylene geomembrane. The useful life of this option is estimated at between 12 and 15 years.
Many of the producers who need these technologies lack the resources to acquire them. For this reason, the company led by this young man has launched ainitiative through the Kiva organization to grant microcredits that allow small farmers to provide their farms with this comprehensive solution to improve manure management.
