The main purpose of this study is to reduce the production cost of cellulase by optimizing the production medium and using an alternative carbon source such as municipal solid waste residue. In the present investigation, we aim to isolate the two novel cellulase producing fungi (Aspergillus niger and Trichoderma sp.) from municipal solid waste. Municipal solid waste residue (4-5% (w/v)) and pep...

in a country like iran, where soil organic matter is less than 1% and in most cases even less than 0.5 %, municipal solid waste (msw) is a permanent and inexpensive source of organic matter. various experiments have indicated that applications of compost improve plant health, yield and nutritional quality. however, the quality of the compost determines the growth and the development of plants. ...

hydrologic evaluation of landfill performance (help) model is one of the most accepted tools to simulate the hydrological attributes of landfills. although some major deviations from real values has been reported about the calculated results for leachate generation by help model but other researchers and/or engineers in practice have used it in some places to estimate amount of leachate produce...

Man has always been proficient producer of waste; however, towards the end of the 20th century saw the upsurge of a new, noxious clutter: the electronic detritus that has come to be known as e-waste. The consumption of electronics: televisions, computers, cell phones, video games, iPods, etc has increased over the last few years, making the electronic industry the world’s largest and fastest gr...

AIM To evaluate the prevalence of hepatitis B virus (HBV) markers among municipal solid waste workers (MSWWs) in Keratsini (Greece). METHODS We assessed in a cross-sectional study the prevalence of biological markers of HBV infection (HbsAg, anti-Hbc, anti-Hbs) and their association with exposure to waste and other socio-demographic factors in 166 municipal employees in Keratsini (Greece). ...

A review is given of gasification processes for solid fuels with special emphasis on waste gasification. Although the co-current moeing bed gasifier has not been under consideration for a long time, it offers interesting possibilitiesJor waste gasification. Some operational data are given. Two potential applications are discussed--gasification of agricultural waste (maize cobs) in the rural are...

An integrated model of municipal waste management of the Czech Republic was developed as a balanced network model for a set of municipal solid waste (MSW) sources (mostly municipalities) connected with a set of chosen waste treatment facilities processing their waste. The model involves composting, energy utilisation, material recycling, and land-filling. It is implemented as a combination of f...

OBJECTIVES Increased concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzo-furans (PCDFs) in pooled blood samples from workers at municipal waste incinerators have been reported. This study was undertaken to confirm these results in individual blood samples from potentially exposed and unexposed workers at municipal waste incinerators compared with matched unex...

Introduction: Countries around the world are looking for an appropriate, stable, and affordable replacement for the natural energies. Therefore, the waste is considered as an available resource to produce energy, which by controlling, its effects on the environment could be minimized. Materials and Methods: To conduct this review article, the scientific data related to the topic were gathered ...
