Bulk waste storage carts are common in hospitals and undoubtedly assist in the day-to-day management of clinical wastes. They are used for the transport and interim storage of primary clinical waste containers and are often located close to or within hospital buildings to receive such wastes from clinical departments. Examination of a random selection of bulk clinical waste carts at nine acute ...

Anaerobic digestion is applied widely to treat the source collected organic fraction of municipal solid wastes (SC-OFMSW). Lipid-rich wastes are a valuable substrate for anaerobic digestion due to their high theoretical methane potential. Nevertheless, although fat, oil and grease waste from sewage treatment plants (STP-FOGW) are commonly disposed of in landfill, European legislation is aimed a...

A laboratory study was carried out on anaerobic digestion of vegetable wastes (brinjal, cabbage, carrot, ladies finger) & flowers (jasmine, sunset flower, Roselle, African wattle, Nile tulip flower, silk tree mimosa.) in a 1L capacity of anaerobic digestor using cow dung as an inoculums. The digester was operated in the ratio of 1:1 of substrate to inoculums at RT. The substrate concentrations ...

the management of hospital wastes is of high importance, because of their infectious and hazardous potential. this is a cross-sectional study based on questionnaire, interview, observation and meetings performed in major mashhad hospitals in 2009. weight and per capita waste production were determined. moreover, the status of production, separation, storage, collection, treatment, transportatio...

The article represents the theoretical, regulatory consolidated information on effectiveness indicesof performance of customs authorities, as well an econometric modeling separate parameters such economic indicators payments, namely weight and cost. developed models according to given are based monthly data Customs statistics for commodity group 23 «Residues wastes food industry; prepared anima...

A brief overview is given of the sources, characteristics, and toxic constituents of municipal solid wastes. Several methods are presented for handling, treating, and disposal of solid wastes. Monitoring the landfill site is necessary; there has been a trend to recognize that municipal solid wastes may be hazardous and to provide separate secure handling, treatment, and disposal for their dange...

This study compared the environmental impacts of composting yard wastes in windrows with using them in place of soil as alternative daily cover (ADC) in landfills. The Life Cycle Assessment was made using the SimaPro LCA software and showed that the ADC scenario is more beneficial for the environment than windrow composting. ADC use is also a less costly means of disposal of yard wastes. This f...

Plasma pyrolysis integrates thermo-chemical properties of plasma using pyrolysis process for safe disposal of solid wastes. It is an environment friendly technology to generate valuable byproducts by converting municipal solid waste, biomedical waste and hazardous wastes at 800-1000°C. Plasma Pyrolysis of plastic wastes generates pyrolysis gas, which can be utilized for energy recovery via diff...

Very little is known about the microbial composition of animal bedding wastes, including poultry litter, and what is known has been deduced from standard culture methods, by which some fastidious organisms that exist in the environment may not be detected. We evaluated the bacterial composition of poultry litter by using a combination of culture and molecular detection. Total aerobic bacteria i...

The concept of microbiological leaching have played a greater role to recover valuable metals from various sulfide minerals or low grade ores during the middle era of twentieth century and that continued till the end of the century. Slowly, due to depletion of ore/minerals, and implementation of stricter environmental rules, microbiological leaching process has been shifted for its application ...
