Deltaway has developed its own WTE power plant concept, called DeltaBox. DeltaBox is a modular, semi-permanent plant that can be barge-mounted, transported, and “plugged into” local power grids. It can be built on-site, or shipped or trucked to destinations at shorelines near or amid urban areas and sources of waste. Based on a 750-tonne-per-day waste throughput module, DeltaBox can also be linked to additional modules if needed, offering certain economies of scale.
DeltaBox’s core incineration system is identical to those used in many U.S. and European facilities and is known to be reliable and highly efficient for fuel consumption and environmental requirements. DeltaBox also incorporates the latest boiler; turbine-generator; and gas, fly ash, and slag collection technologies. At 750 tonnes per day, DeltaBox offers four primary advantages:
• Standardization of available off-the-shelf equipment,
• Optimized investment cost for target markets,
• A module size ideal for upscaling as needed, and
• Highly efficient energy output.
Because DeltaBox occupies a small land footprint or even can be anchored on water, it minimizes impact on limited land resources. Additionally, its built-in systems desalinate seawater for steam and other plant needs, thereby reducing impact on scarce fresh water supplies. This makes it a particularly viable option in developing market population centers, the largest of which are coastal. In regions such as Asia, where waste tipping fees are low and power purchase agreements are high-priced, DeltaBox can still operate profitably on power sales alone.
