Dry Anaerobic Digestion: SMARTFERM Batch Processing
Batch Dry AD Technology
Zero Waste Energy offers a high-solids, batch processing anaerobic digestion design for facilities starting as low as 5,000 TPY and up to 90,000 TPY of almost any organic material utilizing SMARTFERM proprietary technology. The batch processing is well suited for the production of biogas from stacked solid organic waste in a non-continuous process. Unlike other dry fermentation technologies, SMARTFERM offers a sub-grade percolate tank, which significantly reduces percolate and biogas process piping runs as well as the size of motors and fans to move them. The sub-grade percolate tank also greatly enhances the overall thermal efficiency of the process. The SMARTFERM design allows for a thermophilic mode of operation and is offered on two platforms: a shop fabricated steel digester system or as a cast-in-place concrete digester system.
All SMARTFERM systems can be designed to include biogas-processing technology for combined heat and power (CHP) generation for both onsite use and export as well as compressed natural gas (CNG) for use to fuel waste transport vehicles. In addition, in-vessel composting (IVC) options can provide partial or complete sanitizing of compost for the wholesale or retail market.
SMARTFERM is offered on two platforms based on the amount of organic waste to be processed: shop fabricated steel digesters or as a cast-in-place concrete digesters (see below for details). Our technology is built in the US specifically for the waste industry.
