“…With very little volatilization of 2,4-D occurred during the composting process, Michel et al (1995) noted with interest that their results indicated an active mineralization of 2,4-D at composting temperatures of 60°C. To elucidate the hazard potential of compost application, Hartlieb et al (2003) amended municipal biowaste with 14 C labelled pyrene and simazine, which they incubated in a pilot-scale composting simulation system. A mass balance incorporating the mineralization, metabolism and sorption of the two model substances was then established over a period of 370 days.…”

Sustainable development requires the development and promotion of environmental management and a constant search for green technologies to treat a wide range of aquatic and terrestrial habitats contaminated by increasing anthropogenic activities. Bioremediation is an increasingly popular alternative to conventional methods for treating waste compounds and media with the possibility to degrade contaminants using natural microbial activity mediated by different consortia of microbial strains. Many studies about bioremediation have been reported and the scientific literature has revealed the progressive emergence of various bioremediation techniques. In this review, we discuss the various in situ and ex situ bioremediation techniques and elaborate on the anaerobic digestion technology, phytoremediation, hyperaccumulation, composting and biosorption for their effectiveness in the biotreatment, stabilization and eventually overall remediation of contaminated strata and environments. The review ends with a note on the recent advances genetic engineering and nanotechnology have had in improving bioremediation. Case studies have also been extensively revisited to support the discussions on biosorption of heavy metals, gene probes used in molecular diagnostics, bioremediation studies of contaminants in vadose soils, bioremediation of oil contaminated soils, bioremediation of contaminants from mining sites, air sparging, slurry phase bioremediation, phytoremediation studies for pollutants and heavy metal hyperaccumulators, and vermicomposting.

“…In addition to HOC mineralization, some fractions of NAPL-associated contaminants can become sequestered within organic matrices through sorption, covalent binding, or hydrophobic interaction and entrapment during biodegradation, forming nonextractable residues [25,26]. The impacts of NAPL characteristics on such processes are, however, largely unknown.…”

The effects of loading and aging pyrene in soils in the presence of four environmentally common nonaqueous-phase liquids (NAPLs) (hexadecane, 2,2,4,4,6,8,8-heptamethylnonane [HMN], toluene, and dimethyl phthalate [DMP]) on its subsequent desorption from those soils, earthworm accumulation, biodegradation, and extractability were tested by using two dissimilar soils. The presence of each of the four NAPLs increased fractions and rates of pyrene desorption, and hexadecane slowed the effects of aging on these same parameters. Loading with hexadecane and HMN caused earthworm accumulation of pyrene to decrease. These results contrast with generally observed faster desorption rates resulting from NAPL addition, suggesting that additional factors (e.g., association of pyrene with NAPL phases and NAPL toxicities to earthworms) may impact bioaccumulation. The presence of HMN and toluene increased pyrene biodegradation, whereas hexadecane and DMP had the opposite effects. These results correlate with changes in the extractability of pyrene from the soils. After aging and biodegradation, hexadecane and DMP substantially increased pyrene residues extractable by methanol and decreased nonextractable fractions, whereas HMN and toluene had the opposite effects.

“…This stage can last for several weeks or months depending on the size of the system and the composition of the ingredients [51,56]. DEHP is resistant to being fully biodegraded during the conventional sludge digestion process [57]; however, the biodegradation of DEHP can be stimulated by thermophilic aerobic sludge digestion (TAD) at the temperatures of approximately [60][61][62][63][64][65][66][67][68][69][70] C [58]. Most microorganisms cannot survive under thermophilic condition and therefore are killed during thermophilic stage.…”

“…The observed decreases were due to the adsorption and/or complexation of VAs to organic compounds and divalent cations present in manures. During composting more VA adsorption sites are generated (as part of the process and due to the feed matrix) [60], and consequently, extractable concentrations of VAs and their metabolites decline with time in high organic matrix [78]. Kim et al [65] investigated the decline in extractable tetracycline (CTC), sulfonamides (SMZ), and macrolides (TYL) during composting.…”

Sewage sludge is a rich source of organic matter and nutrients, which can be utilized for soil improvement and plant growth. The utilization of sewage sludge for plant growth and conversion of sludge into renewable resource is often restricted by the presence of hazardous organic matter (HOM) including di-(2-ethylhexyl) phthalate (DEHP) and antibiotics. HOM enters the sewerage system through various domestic and industrial sources; they are mostly hydrophobic in nature and recalcitrant to microorganisms. HOM has the tendency to accumulate in the sludge during biological wastewater treatment processes and, subsequently, raise the difficulty of further sludge treatment and/or disposal. The application of sewage sludge containing HOM can create risk to ecosystems. The stability and biodegradation of DEHP and antibiotics during composting are discussed in this chapter. Finally, the recent advances in the bioremoval of these HOM are briefly summarized.
