The wastes generated in the Faculty of Physical Sciences shopping complex and offices on daily basis for a period of one week continuous sampling have been determined. The summation of the wastes generated amounted to 355.38kg; the volume was arrived at following the daily scientific survey by gathering all wastes matrix generated in a particular day followed by manual sorting and weighing of t...

The alkaline-tolerant marine-derived fungus Chaetomium globosum was tested for the production of enhanced levels of cellulases and free phenolics under highly alkaline conditions using agro wastes (cotton seed, sugar cane bagasse) as substrates under solid state fermentation (SSF) processes. In both the agro wastes used, an increase in cellulases (β-endoglucanase, β-Glucosidase, and β-exoglucan...

Egg breaking wastes were treated with 1W200 mg./l. chitosan, a by-product /derived from shrimp and crab shells, and 2-20 mg./l. Betz 1130. Suspended solids in the .I wastewater were reduced by 70-90% and the COD by 55-75%. The yield of dry coagulated solids from wastes collected during cleanup was approximately 12 lb./IOKl gal., and from the concentrated wastes in the egg washers, the yield was...

background : due to the crucial role of dental solid waste in the spreading of pathogens and threats to human health and the environment, its optimal management is very important. methods: this was a descriptive cross-sectional study. the study population consisted of 40 dental centers, from among which 11 dental centers were selected through random sampling. from each center, 3 samples were co...

The carbonization of coal to produce metallurgical coke is an alternative route for the feedstock recycling of plastic wastes of different structures and origins. Individual plastics or mixed plastics of domestic origin can be incorporated into typical coking blends as secondary raw materials. The effects of the composition of the plastic wastes on the thermoplastic properties of coal, coking p...

Lactic acid can be produced by fermentation of organic matters present in various wastes with the addition of various carbon and nitrogen sources using Lactobacillus species. Organic wastes form kitchen garbage and foodprocessing industries are especially rich in carbon and moisture content. The present study investigates the treatment of the organic wastes using microbiological process for eff...

I n common with most industrial processing industries, the fermentation industries are concerned with waste disposal situations that often become critical. Fermentation wastes usually occur in liquid or solid forms, although some gaseous wastes are also produced. It is worthy of note that, in addition to the problems involved, the disposal of these wastes is particularly interesting to fermenta...

(1) Potential uses of photosynthetie bacteria in the recycling of human wastes have been considered. I t is concluded that systems using photosynthetic bacteria may have advantages over purely algal systems under conditions where total recycling is needed and energy is not abundant. (2) Two systems are proposed in which the metabolic potential of the photosynthetic bacteria might be realized. B...
