Background Animal and municipal solid wastes (MSW) create environmental pollution. It is one of the most challenging problems which require attention. Efforts were made for the conversion and eco-management of animal and municipal wastes into safe and hygienic products by an epigeic earthworm Eisenia fetida. The excess use of chemical fertilizer and synthetic pesticide has […]
Background Water hyacinth (Eichhorniacrassipes) is one of the most uncompromising weeds in the whole world. Its adverse effects due to fast growth rate are main physical interference with fishing and navigation. Water hyacinth also causes eutrophication due to the large release of organic nutrients after its degradation, consequentially deterioration of water quality and also adversely […]
Background The disposal of sugar mill effluent has become a major problem in India due to generation of huge volume of effluent. The value of wastewater for crop production has been recognized in many countries, including India. The effluents not only contain nutrients that stimulate growth of many crops, but also may have various toxic […]
There is a widespread interest in converting organic waste into compost fertilizer to extend the life of landfills, create economic and environmental benefits, and ultimately reduce the pressure on local governments in managing the ever-increasing complexity of municipal solid waste. However, composting is still seldom considered as a strategic element. There is also very little […]
Background This experiment was conducted to study the effect of diet contained mushroom spent wheat straw (MSWS) remained from Agaricus bisporus mushroom as well as the physical form of the diet on the performance of the feedlot calves. At the end of mushroom harvesting period, MSWS was collected from production room and the casing soil […]
Background Over the years, the use of organic materials in farming has reduced due to the increase in the use of chemical fertilizers which are rich in readily available plant nutrients. Intensive use of inorganic fertilizers may have depressing effect on yield of watermelon. Field experiment was conducted at the Teaching and Research Farm, Kwara […]
Introduction In Europe, because of the high production levels of livestock farming in general and pig farming in particular, animal waste management has become increasingly important to comply with the required lowering of livestock farming environmental pressure. Usually manures undergo solid/liquid separation, which generates one clarified liquid fraction and one nutrient-rich solid fraction suitable for […]
Background A study was carried out to classify municipal solid waste (MSW) compost produced in Delhi, India for their marketability and use in different area with respect to physico-chemical properties, fertilizing and heavy metal polluting potentials. Results The pH of the compost was slightly alkaline (8.4 ± 0.02) and C:N ratio (9.46 ± 0.91) was […]
Introduction Total coffee production in the world in 2013 was 8.7 million Mg of coffee beans. Coffee must be processed after harvest to separate beans from the husk, and the post-harvest process can generate different types of residues. Knowing that 50 % of the harvested coffee is husk, it is important to consider that these […]
Background Mushroom wastes are widely left from mushroom production industries and have been supposed to possess prebiotic, antimicrobial, antifungal and antioxidant properties. Due to difficulties with using antibiotic growth promoters in poultry diet, mushroom wastes seem to be a proper substitute for them. Therefore, present experiment was carried out to investigate the effect of oyster […]
