The objectives of this study were to identify the perceptions of nursing workers regarding the handling of hazardous chemical waste at the University of São Paulo University Hospital (HU-USP), and develop a proposal to improve safety measures. This study used a qualitative approach and a convenience sample consisting of eighteen nursing workers. Data collection was performed through focal group...

Considerable attention has been given to chemical methods of reducing the Biochemical Oxygen Demand (B.O.D.) of semi-chemical neutral sulfite waste (S.N.W.). Very little study has been devoted to a biological method. The exact composition of this paper industry waste will vary with the type of wood chip used and the modification of cook. Table 1 shows a typical composition of the liquor resulti...

The research presented in this manuscript is focused on the pyrolysis of waste pharmaceutical blisters, which are a large and neglected group waste, that could be possibly recovered. studies were analysis chemical composition, as well fuel properties char generated during process its possible applications. temperatures (400, 425, 450 °C) determined based thermogravimetric study was performed pr...

Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of wa...

The analysis of solid waste or incinerated residue for information regarding the chemical constituents involved the development and adoption of analytical methods. Methods were developed for the determination of nitro­ gen, carbon, hydrogen, protein, chemically decomposable organic and calorific values. The chemical composition of two types of residue and unburned solid waste was de­ termined u...
