The effect of various animal wastes on growth and reproduction of an epigeic earthworm Eisenia foetida was studied under identical laboratory conditions. For each waste, viz., cow, buffalo, horse, donkey, sheep, goat and camel, five hatchlings per 100 g of waste were inoculated and monitored for biomass gain, mortality, sexual maturity, cocoons production periodically for 15 weeks. No mortality...

Jamaican agro-industries generate large quantities of wastes, which are either discarded or under-utilized. In order to evaluate the possible utilization of these wastes, it is necessary that the profiles of the major biochemical groups be developed. This paper describes the determination of the amino acid composition of coffee, citrus, and rum distillery wastes using a reversed-phase high-perf...

The growth of the biobased economy will lead to an increase in new biorefinery activities. All biorefineries face the regular challenges of efficiently and economically treating their effluent to be compatible with local discharge requirements and to minimize net water consumption. The amount of wastes resulting from biorefineries industry is exponentially growing. The valorization of such wast...

In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...

hospital wastes are one of most important environmental problems because of their hazardous, toxic and pathogenic characteristics. the aims of this study were to identify and measure the amount of hospital wastes and classify of them according to who criteria in amirolmomenin(as) hospital and shahid rajaei policlinic in ahwaz, sw of iran. this research was a field-descriptive study. initially, ...

in this study, the chemical composition of the tea wastes determined. the value of dry matter, organic matter, crude protein, crude fiber, calcium and phosphorous 95, 94, 13.3, 23.1, 0.011 and 0.29 percent, respectively. in the experiment of digestibility by animal, five experimental rations (including tea waste and alfalfa in the proportion of 0:100, 10:90, 20:80, 25:75 and 30:70 percent) and ...

The SAPICO2 project is an INTERREG IVA cross channel collaboration established to develop new technologies utilising accelerated carbonation for the creation of eco-construction materials from solid wastes. Over three phases, the project has identified carbon dioxide reactivity of solid wastes, produced prototype-construction materials (from these wastes), and manufactured bulk samples of carbo...

The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...

Temple puja wastes are released in water bodies or land creating severe environmental pollution and health hazards. The temple wastes extract was used to isolate the Bacillus megaterium for the production of enzyme penicillin amidase as it recorded the largest zone of activity. The result obtained showed that on nutrient agar medium the grown colonies were confirmed by gram staining as Bacillus...

OBJECTIVES to evaluate the heterogeneity of biomedical waste (BW) using Nightingale charts. METHOD cross-sectional study consisting of data collection on wastes (direct observation of receptacles, physical characterisation, and gravimetric composition), development of a Management Information System, and creation of statistical charts. RESULTS the wastes with the greatest degree of heteroge...
