The biogas plant SanMartin is the most advanced industrial biogas plant in Nicaragua and represents the latest state of the art technology. This plant is able to energetically utilize almost all kinds of waste produced from the slaughterhouse, tannery facility and feedlot from the company group Industrial Comercial San Martin S.A.

The first stage of the project was started in 2015 and the commissioning in 2016.

The second stage (expansion phase) was executed in 2017 with commissioning of the second digester in the same year.

Agrinz Technologies GmbH was responsible for the technology, the entire process engineering and project management (detail and execution planning, supervision and coordination, operator training, handing over and commissioning) . Since the plants ‘commissioning Agrinz has been providing after sales service and process consulting.
