In this study, the possibility of using tea production waste as a new casing material in mushroom (Agaricus bisporus) cultivation was investigated. Some physical and chemical characteristics of tea waste, fermented tea waste and a mixture of tea waste with peat were compared with that of peat casing, as were their effects on yield. The highest yield was obtained from peat casing. Using tea prod...

We report the use of a simple yet highly effective magnetite-waste tea composite to remove lead(II) (Pb(2+)) ions from water. Magnetite-waste tea composites were dispersed in four different types of water-deionized (DI), artificial rainwater, artificial groundwater and artificial freshwater-that mimic actual environmental conditions. The water samples had varying initial concentrations (0.16-5....

the adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol a on locally available black tea leaves waste and granular activated carbon were investigated. the results obtained indicated that the kinetics of adsorption were ph, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...

Changes in black tea quality were studied for three subsequent years and in different times of plucking (spring, summer and autumn) in the form of two leaves and a bud. Percentage of waste, total sensory scores, total soluble solid, caffeine, theaflavin, thearobigin, total color and brightness were evaluated in black tea. The data were analyzed in split plot design based on randomized complete ...

A novel multi-metal binding biosorbent (MMBB) was developed by combining a group of three from the selective natural lignocellulosic agro-industrial wastes for effectively eliminating lead, cadmium, copper and zinc from aqueous solutions. Four MMBBs with different combinations (MMBB1: tea waste, corncob, sugarcane bagasse; MMBB2: tea waste, corncob and sawdust; MMBB3: tea waste, corncob and app...

Waste from tea, a beverage globally consumed is a common menace discarded to the environment thereby contributing to environmental pollution. The textile and paper industries have also been major culprits in the pollution of the environment through their indiscriminate discharge of dye solutions. These dyes are carcinogenic, mutagenic, and generally harmful to the entire eco-system; this has po...

Dengue mosquitoes are evolving into a broader global public health menace, with relentless outbreaks and the rise in number of Zika virus disease cases as reminders of the continued hazard associated with Aedes vectors. The use of chemical insecticides-the principal strategy against mosquito vectors-has been greatly impeded due to the development of insecticide resistance and the shrinking spec...

Soil samples were collected from three different habitats at monthly intervals. Order Oribatida was the highest numerically abundant group of acrarines followed by order Mesostigmata. ANOVA indicated significant difference (p<0.05) in population density of oribatid mites among the sites. Five, eight and ten species of oribatid mites were recorded from the waste disposal site at Panga, Denguajha...
