conclusions considering the weight percentage of food wastes (70%), solid wastes of babolsar city could be used for composting. also as large quantities of infectious wastes were produced by hospitals of babolsar, it is recommended that sterilization systems (hydroclave) be used for decontamination of these hazardous wastes. materials and methods this study was a descriptive and cross-sectional...

Solid-state fermentation (SSF) is envisioned as a prominent bio conversion technique to transform natural raw materials into a wide variety of chemical as well as biochemical products. SSF is being successfully exploited for food production, fuels, enzymes, antibiotics, animal feeds and also for dye degradation. The reuse of agro-industrial wastes in SSF processes is of particular interest due ...

Conservation agriculture (CA) integrates ecological management with scientific agricultural production. CA promotes minimal disturbance of the soil by tillage (zero tillage), balanced application of chemical inputs (only as required for improved soil quality and healthy crop and animal production), and careful management of residues and wastes. CA Promotes application of fertilizers, pesticides...

Most livestock and poultry odors are generated by the anaerobic decomposition of livestock wastes such as manure (feces and urine), spilled feed, bedding materials, and wash water. Increased organic loading rates due to expanding animal numbers, slug loading, concentrated waste streams, and/or inadequate amounts of dilution water increase the potential for odor emissions from waste management s...
