To reduce costs at food processors, Advetec has launched the Advetec XO, an evolution of its biothermic digester (BTD) technology.
Designed initially for industrial food and drink manufacturers which currently pay for organic waste disposal to be collected and processed off-site, the Advetec XO is a small footprint, fully contained on-site solution.
It delivers a 60-90% reduction in mass from mixed organic waste streams, with typical opex cost savings of 10% to 15% from the first day of operation.
The process uses a bespoke blend of thermophilic bacteria and nutrients to digest the organic content of waste, utilising an exothermic reaction. This generates heat which sustains the high- emperature environment required for the thermophilic bacteria,and ensures low energy cost.
Waste is digested as it moves through the Advetec XO, producing water vapour that can be condensed or vented to atmosphere. The remaining output material is dry with a potentially high calorific value.
The completely re-engineered solution includes a range of improvements to both the mechanical integrity of the machine and internal processes, as well as the control software and remote monitoring systems. These help to improve performance capabilities with different waste streams, with overall efficiency gains of 10% on previous models.
Cycle times for waste digestion as material passes through the machine are now between 24 and 72 hours, depending on density and composition of the waste.
The Advetec XO is said to be the only on-site solution which can handle non-organic waste contained within the organics. This gives operators the benefits and flexibility of not needing to sort or treat waste prior to processing.
