The installation of the moving floor and compactor at our Corio Road Transfer Station has provided a most positive community outcome. It has been a great experience working with OREZ to bring the project to fruition, the team were always open to learnings, responsive and happy to collaborate to achieve a beneficial outcome for the Shire of Murray.
Shire of Murray
We engaged OREZ through an ECI contract to provide us with a comprehensive preliminary design package for our new In-Vessel Composting facility. We required them to integrate four tunnels plus all supporting auxiliaries into an existing structure. Their expertise ensured a design capable of processing a diverse range of waste streams, including FOGO, Green Organics, and liquid/sludges. We appreciated OREZ’s expertise and professionalism and look forward to progressing our project into the construction phase shortly.
