During biogas production, the rate-determining step for the conversion of complex organic matter is the hydrolysis. Different pretreatment methods aid in facilitating the anaerobic digestion by increasing the rate of organic matter hydrolysis. This in effect results in enhanced production of biogas and aids in waste stabilization as well as disposal. This review gives an overview of the methods...

The objective of this study was to identify the components, composition, generation rate and management of dental waste in Urmia, Iran. Fifteen dental centers including eight general dental offices, five specialist dental offices and two dental clinics were selected and two samples were taken from each office. Then, the wastes were manually separated in 31 components and weighted. The results s...

The key to waste minimization in fine chemicals manufacture is the widespread substitution of classical organic syntheses employing stoichiometric amounts of inorganic reagents with cleaner, catalytic alternatives. The E factors (by waste per kg product) of chemical processes increase dramatically on going downstream from bulk to fine chemicals and pharmaceuticals, mainly owing to the use of “s...

We consider a Periodic Load-dependent Capacitated Vehicle Routing Problem (PLCVRP) encountered by medical centers and medical waste collection companies for the design of a weekly inventory routing schedule to transport medical wastes to treatment sites. In addition to minimization of transportation risk, occupational risk related to temporary storage of hazardous wastes at the health-care cent...

This study examined the relationship between team culture and corporate performance. The objectives of are to examine how dimensions culture, such as collaboration, interdependence, shared goals, affect performance, product quality, time minimization, waste minimization. A survey literature was used a source data collection. following were findings: Collaboration improves Interdependence enhanc...

Construction wastes have become the major source of solid wastes in Hong Kong. Thousands of tonnes of solid wastes are produced every year from construction and demolition activities. Increasing generation of these wastes has caused significant impacts on the environment and aroused growing public concerns. Therefore, the minimization of construction wastes has become a pressing issue. This pap...

Construction waste is considered as a major contributor of solid wastes in municipal landfills. Construction, renovation, and demolition (CRD) waste generated by the Canadian construction industry accounts for 27% of total municipal solid waste disposed in landfills. However, many researchers stated that 75% of what the construction industry generates as waste has a residual value and therefore...
