Formed in 2004, we have delivered 'no nonsense' practical help to those wishing to pursue low carbon alternative energy supplies utilising biomass.

Stewart Thermal has a unique understanding of the process requirements for the small and large scale generation of electricity and/or heat from biomass.

We are able to support biomass energy conversion projects into operational use, including their mobilisation and day-to-day operations and maintenance.

Stewart Thermal recognises the importance of supporting projects holistically, enabling a design concept to deliver the required outputs – cost effectively. Our approach to operational and maintenance management is geared to minimise on-costs, thereby protecting the bottom line and enabling best practice to become part of the plant management culture.
