Four different tests to assess compost stability were compared during green waste composting in windrows at a largescale composting plant. The tests used were: germination index, (based on seed germination); SOUR (specific oxygen uptake rate, respirometric method based on O2 consumption by the microorganisms); self-heating test, (reflecting the energy output from the aerobic process); and Solvi...

Olive leaves are an agricultural waste of the olive-oil industry representing up to 10% of the dry weight arriving at olive mills. Disposal of this waste adds additional expense to farmers. Olive leaves have been shown to have a high concentration of phenolic compounds. In an attempt to utilize this waste product for phenolic compounds, we optimized their extraction using water-a "green" extrac...

Decentralized eco-sanitation system is a promising and sustainable mode comparing to the century-old centralized conventional sanitation system. The decentralized concept relies on an environmentally and economically sound management of water, nutrient and energy fluxes. Source-separation systems for urban waste management collect different solid waste and wastewater streams separately to facil...

The increased concern about environmental problems caused by inadequate waste management, as well as the concern about global warming, promotes actions toward a sustainable management of the organic fraction of the waste. Landfills, the most common means to dispose of municipal solid waste (MSW), lead to the conversion of the organic waste to biogas, containing about 50% methane, a very active ...

Recycling of coffee pulp waste for composting is a time taken process and to reduce the composting period developing efficient decomposing microorganism is needed. The relationship between microorganism and its enzymatic activities lead for the better understanding to develop microbial consortium for effective composting. In the present study the organisms were screened which produces enzymes l...

Composting is a solid waste treatment process consisting of the biochemical degradation of organic materials. A controlled microbial aerobic decomposition produces stabilized organic materials to be used as soil conditioners or organic fertilizers. The efficiency of this process is strongly temperature-dependent and the key to successful composting lies in the tracking of an appropriate tempera...

escalating development of tourism and petroleum industries in small islands such as lavan-iranrequires sound solid waste management. in the present investigation, three scenarios which consist of thecombination of landfill, recycling, incineration and composting and their environmental impacts have beenevaluated for 7514 kg/day of waste generation in lavan island. for this purpose, life cycle a...

Municipal solid waste contains high amounts of cellulose, which is an ideal organic waste for the growth of most of microorganism as well as composting by potential microbes. In the present study, Congo red test was performed for screening of microorganism, and, after selecting a potential strains, it was further used for biodegradation of organic municipal solid waste. Forty nine out of the 25...

Survival of bovine enterovirus was studied in animal by-products subjected to sanitization processes. Composting technology and anaerobic digestion under mesophilic (37 °C) and thermophilic (55 °C) conditions were tested in terms of their effectiveness. Viruses were introduced into the biomass in the course of waste treatment processes and virus titres were determined at appropriate time interv...
