  • Heterogeneous photodegradation of methylene blue with iron and tea or coffee polyphenols in aqueous solutions

    Recently, we developed two new Fenton catalysts using iron (Fe) and spent tea leaves or coffee grounds as raw material. In this study, Fe-to-tea or Fe-to-coffee polyphenol complexes were successfully tested as heterogeneous photo-Fenton catalysts. The photodegradation efficiency of methylene blue solutions with Fe-to-polyphenol complexes was higher than that of homogeneous iron salts in the ...

  • Dynamic uptake of drug norfloxacin from aqueous solution using spent tea leaves as a sorbent

    This work describes sorptive removal of antibiotic drug norfloxacin using spent tea leaves (STL) as a cost effective sorbent. The specific surface area (BET) of spent tea leaves was 1.141 m 2 gm –1 . The effect of pH, initial concentration of drug, contact time and particle size on the extent of adsorption were studied. The kinetic uptake data were best interpreted by pseudo second order ...

  • Influence of some biological wastes and their combination on growth and reproduction potential of earthworm, Eisenia fetida and their effect on plant growth

    Effect on growth and reproduction potential of animal wastes viz., cow, goat, horse and a domestic waste (used tea dust) and their combinations to the earthworm, Eisenia fetida, was studied under laboratory conditions. The effect of above on growth aspects of Bhendi crop was compared with the normal compost individually under green house conditions. The effects on growth were assessed for ten ...

  • Coffee`s new uses saves manufacturer big money - case study

    For over a decade Sustainable Resources Group (SRG) has provided this client with turnkey service providing beneficial re-use of residuals from the production of coffee and tea beverages. SRG manages the use of 43,000 tons of bulk residuals and another 7.3 million gallons of liquid residuals annually. Local land application of the plant’s wastewater treatment residuals as a liquid ...

  • Farm size and economic efficiency: a case study of tea production in West Bengal

    Once tea was the major source of export earnings for India, but now India is trailing behind in the field of tea production and exports. Darjeeling tea is considered as India?s pride and almost entire production are exported. The depressed tea export of India actually caused the breakdown of the tea industry in West Bengal. Under such circumstances, it is appropriate to verify whether the tea ...

  • The effects of municipal solid waste compost and compost tea on mineral element uptake and fruit quality of strawberries

    Three levels of municipal solid waste compost (MSWC) and two application rates of compost tea made with MSWC were applied to strawberries for two years. The highest level of application of MSWC significantly increased the concentrations of most extractable soil mineral elements except for Ni which was increased in the highest compost tea application rate. Despite large differences in soil mineral ...

  • Nitrogen uptake by radish, spinach and “Chingensai” from composted tea leaves, coffee waste and kitchen garbage

    A pot experiment was conducted to determine the effects of the application of composted tea leaves (TC), coffee waste (CC), and kitchen garbage (KC) on the nitrogen and nitrate accumulated in radish (Raphanus sativus L. cv. 'radicula pers'), Chingensai (Brassica campestris L. cv. 'Choyo No. 2'), and spinach (Spinacia oleracea L. cv. 'Ban chu paruku') as compared with the effect of inorganic 15N ...

  • Content of magnesium in Ginkgo biloba leaves

    The aim of this study was to investigate the content of magnesium in Ginkgo biloba leaves and compared with those Urtica dioica. The magnesium was determined by atomic absorption spectrophotometry: Ginkgo biloba leaves contained (456 ?g/g) of Mg and Urtica dioica leaves 396 ?g/g. The concentration of magnesium in the aqueous extracts prepared from Ginkgo biloba leaves was about two-fold higher ...

  • Sustainability of Current Agricultural Practices in The Cameron Highlands, Malaysia

    Cameron Highlands is a mountainous region with steep slopes. Gradients exceeding 20∘ are common. The climate is favourable to the cultivation of tea, sub-tropical vegetables and flowers (under rain-shelter). Crop production is sustained by high fertiliser and manure applications. However, agriculture in this environment is characterised by high levels of soil erosion and environmental ...

  • Prediction of Soil and Nutrient Losses in A Highland Catchment

    Highland catchments in tropical regions are frequently subjected to soil erosion and the transport of chemicals downstream. Any drastic changes in land use will increase the severity of these processes of land degradation. A simulation study using GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) was conducted at a catchment presently under tea farming in Cameron Highlands, ...

  • Technical efficiency of organic tea smallholding sector in Sri Lanka: a stochastic frontier analysis

    Organic tea is emerging as a major farming activity in Sri Lanka. In this paper, using a stochastic frontier analysis, we analyse the technical efficiency of organic tea smallholdings in the mid country wet zone of Sri Lanka. The Cobb-Douglas functional specifications are found to be an adequate representation of the cross-sectional data obtained in 2002. Our results indicate that there is great ...

  • Organics in Action : Sustainable Practices Thrive In A National Park

    The Presidio is part of California’s Golden Gate National Recreation Area and the national park system. As an urban park on the northern edge of San Francisco, there are many challenges to be met in the quest to be a model of sustainability. An innovative composting program is becoming one way to help meet the park’s goals. Nearing the close of its second year, this program is well on its ...

  • Evaluating Microbiology of Compost

    The fact that not all compost is created equal has both producers and growers looking for ways to successfully evaluate compost quality. Traditional compost analysis has focused on NPK and micronutrient concentrations in an effort to mirror fertilizer analysis. Compost, however, is much more complex than fertilizer and its most significant value to the grower may be far more than its mineral ...
