The New Slurrycarb™ Process, Under Construction in Rialto, CA, will Convert Biosolids to a Renewable Fuel
Abstract:The current trend in California biosolids management is less Class B land application and more production of Class A products. Agencies that land fill biosolids, along with the few that incinerate, are concerned that these practices may disappear because of changing regulations and the perception that these methods waste a resource instead of recycling. Some agencies are hauling biosolids to Arizona and Nevada for Class B land application or land filling, but these options are not guaranteed for the long term. Two counties in Arizona have already restricted biosolids practices. California and two of its major cities have set aggressive goals for increasing the amount of energy produced from renewable sources.
Since July 2006, three new major biosolids processing facilities in Southern California have either broken ground or started operations. These include two composting facilities and EnerTech's renewable fuel facility.
EnerTech's 883 wet tons per day regional biosolids processing facility in Rialto, California began construction in April 2007 and should start receiving biosolids in September 2008. This energy efficient process will convert biosolids into a renewable fuel which will be used in lieu of coal in a cement kiln. This unique beneficial use reduces fossil fuel and raw material consumption and provides permanent recycling of the biosolids. This paper will discuss the final design criteria, construction status, and start-up schedule for this facility.
