Biogas upgrading unit for Latvian SIA ZAAO commissioned

Membrane technology-based biogas upgrading unit, BIOupgrade, as well as the gas filling station and the high pressure storage facility have now been officially commissioned and handed over to the customer in Latvia. Over the past weeks, the Biovoima project and commissioning team has been carrying out finalisation work at the SIA ZAAO facility, conducting performance tests and training the operators of the facility.

After commissioning and handover, the cooperation with the customer will continue, as the Biovoima's service business BIOservice is responsible for scheduled maintenance during the warranty period. BIOservice supports the customer by ensuring high availability, reliability, efficiency and safety of the equipment and processes, as well as by managing the entire life cycle of the solution.

Biogas upgrading unit and filling station for SIA ZAAO

New biomethane production and use concept BIOupgrade upgrading unit, filling station and the high-pressure storage facility support SIA ZAAO's goals of environmental sustainability, operational efficiency and energy self-sufficiency, producing biomethane in an energy- and cost-efficient manner. With the introduction of the new solutions, waste collection trucks will no longer have to drive far to refuel, but will be able to refuel on their own premises.

ZAAO Development Director Mārtiņš Niklass said earlier in the project that he was happy to work with Biovoima: “We trust Biovoima's expertise in biogas upgrading technology and their professional project execution.”
