“…These objectives are also applicable to remediation projects that use composting to degrade hazardous substances into innocuous end products.The process of compost bioremediation is similar to what occurs biologically in soil; however, composting may accelerate the destruction of contaminants (Buyuksonmez et al, 1999;Rao et al, 1996;Williams microbes → & Keehan, 1993).The composting process is primarily facilitated by a high concentration of biodegradable organic material in the compost matrix and an active microbial population. Such compost offers a good nutrient source for microbes (Laine & Jorgensen, 1996).…”

“…-diamine] was low during composting of atrazine-amended poplar wood (Populus sp. L.) or corn cobs (Zea mays L.) at three temperatures, suggesting no relationship between atrazine and mineralization of these lignocellulosic substrates [48]; however, mineralization of atrazine was enhanced by cocomposting with newsprint [47]. Composting destroyed nearly half of the 2,4-D (2,4-dichlorophenoxyacetic acid) residues of lawn clippings [69].…”

“…The processes of remediation in compost are similar to those that occur biologically in soil. However, composting may accelerate the destruction of contaminants [15,34,47,48]. Temperatures are generally higher in composts than in soils, resulting in increased solubility of contaminants and higher metabolic activity in composts.…”

Hazardous organic and metallic residues or by-products can enter into plants, soils, and sediments from processes associated with domestic, municipal, agricultural, industrial, and military activities. Handling, ingestion, application to land or other distributions of the contaminated materials into the environment might render harm to humans, livestock, wildlife, crops, or native plants. Considerable remediation of the hazardous wastes or contaminated plants, soils, and sediments can be accomplished by composting. High microbial diversity and activity during composting, due to the abundance of substrates in feedstocks, promotes degradation of xenobiotic organic compounds, such as pesticides, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). For composting of contaminated soils, noncontaminated organic matter should be cocomposted with the soils. Metallic pollutants are not degraded during composting but may be converted into organic combinations that have less bioavailability than mineral combinations of the metals. Degradation of organic contaminants in soils is facilitated by addition of composted or raw organic matter, thereby increasing the substrate levels for cometabolism of the contaminants. Similar to the composting of soils in vessels or piles, the on-site addition of organic matter to soils (sheet composting) accelerates degradation of organic pollutants and binds metallic pollutants. Recalcitrant materials, such as organochlorines, may not undergo degradation in composts or in soils, and the effects of forming organic complexes with metallic pollutants may be nonpermanent or short lived. The general conclusion is, however, that composting degrades or binds pollutants to innocuous levels or into innocuous compounds in the finished product.

Microorganisms play an important role in the recycling of agricultural wastes. The compost generated by bioconversion of agroresidues offers several benefits such as enhanced soil fertility and soil health which can lead to increased agricultural productivity, improved soil biodiversity, reduced ecological risks and a healthier environment. These virtues make composting an ideal option for processing of the enormous quantities of agrowastes that are generated in the world. Recent reports also indicate multifarious uses of bioaugmented compost as carrier for bioinoculants, biocontrol agents for diseases suppressivness and bioremediation. There is definite need to intensify research on novel effective microorganisms to prepare high quality compost in a relatively shorter duration and new technologies for large-scale production.
