“…The pilot study of thermophilic sole digestion of organic fraction of restaurant solid waste of the Los Angeles airport was not focused on parameter optimization, but on the degradability of organic fraction of restaurant solid waste ( Hernandez et al, 2001 ). This study proved that implementation of codigestion of this waste stream with municipal sludge at Hyperion WWTP could be possible without foreseeable major problems.…”

“…Hence, systems for suspending or removing these floating layers should be recommended for full‐scale applications if the waste is difficult to suspend. For digestion of food waste, Hernandez et al (2001) reported that this waste did not contain grits. However, it needed grounding to provide a fluidized slurry that can easily be fed and to enhance anaerobic digestion.…”

“…The Environmental Engineering Division of the City of Los Angeles, California, performed a pilot study of thermophilic (54°C) anaerobic digestion of organic fraction of restaurant solid waste collected at the Los Angeles airport ( Hernandez et al, 2001 ). The objective was to evaluate the potential of codigestion of organic fraction of restaurant solid waste in thermophilic digesters at the Hyperion Treatment Plant (Los Angeles, California).…”

Codigestion of organic wastes is a technology that is increasingly being applied for simultaneous treatment of several solid and liquid organic wastes. The main advantages of this technology are improved methane yield because of the supply of additional nutrients from the codigestates and more efficient use of equipment and cost‐sharing by processing multiple waste streams in a single facility. Many municipal wastewater treatment plants (WWTPs) in industrialized countries currently process wastewater sludge in large digesters. Codigestion of organic wastes with municipal wastewater sludge can increase digester gas production and provide savings in the overall energy costs of plant operations. Methane recovery also helps to reduce the emission of greenhouse gases to the atmosphere. The goal of this literature survey was to summarize the research conducted in the last four years on anaerobic codigestion to identify applications of codigestion at WWTPs. Because the solids content in municipal wastewater sludge is low, this survey only focuses on codigestion processes operated at relative low solids content (slurry mode). Semi‐solid or solid codigestion processes were not included.    Municipal wastewater sludge, the organic fraction of municipal solid waste, and cattle manure (CAM) are the main wastes most often used in codigestion processes. Wastes that are codigested with these main wastes are wood wastes, industrial organic wastes, and farm wastes. These are referred to in this survey as codigestates. The literature provides many laboratory studies (batch assays and bench‐scale digesters) that assess the digestibility of codigestates and evaluate the performance and monitoring of codigestion, inhibition of digestion by codigestates, the design of the process (e.g., single‐stage or two‐stage processes), and the operation temperature (e.g., mesophilic or thermophilic). Only a few reports on pilot‐ and full‐scale studies were found. These evaluate general process performance and pretreatment of codigestates, energy production, and treatment costs.

“…The thermophilically digested sludge was more odorous than the mesophilic sludge, however, the centrifuged cake from thermophilic operation was less odorous than the mesophilic cake. Hernandez et al (2002) reported on a research program to evaluate advanced digestion technologies at the Hyperion wastewater treatment plant.…”

This review section covers journal articles and conference papers related to biosolids and sludge management that were published in 2002. The literature review has been divided into the following sections:• Regulations and biosolids management planning,• Biosolids characteristics and measurement,• Odor issues,• Sludge treatment technologies, and • Disposal and reuse. The biosolids characteristics and measurement section includes stability, metals, nutrients, synthetic organics, and pathogens. An entire section was devoted to odor issues since a host of relevant papers were identified from the Water Environment Federation's Odors and Toxic Air Emissions 2002 Conference in Albuquerque, New Mexico. The sludge treatment technologies include: pretreatment, anaerobic digestion, aerobic digestion, dewatering, drying, composting, alkaline stabilization, and innovative treatments. A vast majority of the treatment papers relate to anaerobic digestion of sludge. The disposal and reuse section considers land filling and land application as disposal options. Much of the literature dealt with the agricultural land application of biosolids/sludge, so that this subsection is also fairly lengthy. Within land Literature Review 2003
