  • A study on Air Filled Porosity evolution in sludge composting

    Air Filled Porosity (AFP) is a key parameter in the composting process, conditioning oxygen availability and heat accumulation. Air pycnometry is considered the most adequate methodology for AFP determination. This technique requires withdrawing a sample of material from the composting mass for AFP measurement, which may alter its physical characteristics. A novel strategy that permits to measure ...

  • Pleurotus ostreatus spent mushroom compost as green biosorbent for nickel (II) biosorption

    The potential of Pleurotus ostreatus spent mushroom compost (PSMC) as a green biosorbent for nickel (II) biosorption was investigated in this study. A novel approach of using the half-saturation concentration of biosorbent to rapidly determine the uptake, kinetics and mechanism of biosorption was employed together with cost per unit uptake analysis to determine the potential of this biosorbent. ...

  • Microbial community composition and reactor performance during hydrogen production in a UASB reactor fed with raw cheese whey inoculated with compost

    This study investigated the microbial community developed in a UASB reactor for hydrogen production and correlated it to reactor performance. The reactor was inoculated with kitchen waste compost and fed with raw cheese whey at two organic loading rates, 20 gCOD/Ld and 30 gCOD/Ld. Hydrogen production was very variable, using an OLR of 30 gCOD/Ld averaged 1.0 LH2/Ld with no methane produced under ...

  • Double vault composting latrine program in Northern Vietnam

    This case study is based from the findings of Plan Vietnam from the investigation made by Ben Cole and John Collet in Ha Nam and Nam Dinh provinces in Vietnam in May and June 2007. The investigation basically tackles the perception and attitude of the people who have been using the double-vault composting (DVC) latrine. Based from studies conducted by the World Bank (WB) thru their Water and ...

  • Review of current European practice of MBT compost-like output use and application to land in relation to environmental protection

    Mechanical-Biological Treatment (MBT) is often a key element in National Strategies for the diversion of Biodegradable Municipal Waste (BMW) from landfill. Unlike incineration, it provides flexibility in the system, which is important in those Member States where the system will have to undergo widespread changes in the amount and quality of residual waste that is dealt with. The main objectives ...

  • Composting dairy solids with the ac composter

    In October, ECS began conducting trials at California State University Fresno to explore using the new patent pending AC Composter system to manage dairy manure solids and comply with air-quality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF's research dairy. This research is being conducted with funds from a USDA Small Business Innovative Research ...

  • Composting in Wiltshire-schools

    Background - St Laurence is a popular 11-18 Church of England Comprehensive School in Bradford- on-Avon, with specialist performing arts status. They achieved their bronze Eco-School status in April 2007 and are well on their way to achieving their silver award. The school's eco-group call themselves ECO (Environmental Care Organisation) and meet every few weeks. The group is facilitated by ...

  • Residence time and contact volume in sloped compost and compost/vegetated filter beds

    Little is known about transport mechanisms in sloped dormant vegetated and compost only filters for roadway runoff. Residence time experiments were carried out in triplicate in 0.254 m wide × 0.65 m long by 0.10 m deep beds using a bromide tracer. Bed slope was 12°. Only at the lowest flow rate tested (0.276 l/min per m of filter width) were mean residence times in compost beds with and without ...

  • Pathogen destruction and solids decomposition in composting latrines: study of fundamental mechanisms and user operation in rural Panama

    The relationship between temperature, high pH, desiccation, decomposition, pathogen destruction, and user operation in active double vault urine diverting (DVUD) composting latrines located in the Bocas del Toro region of Panama was assessed. Latrine samples were analyzed for temperature, pH, % moisture, carbon-to-nitrogen (C/N) ratio, and presence of specific pathogens. Surveys and visual ...

  • Sludge composting, sludge pretreatment and radiation technology: a review

    The paper reviews the state-of-the-art technologies on sludge conditioning and stabilisation. Radiation technology, best contextualised within the concept of Green Chemistry, is yet another developing area of sludge pretreatment. Besides revisiting some important aspects of sludge treatment by composting, this review paper also appraises the application of gamma ray and ultrasound irradiations ...

  • The effects of bioadditive in the form of yeasts and zeolite on the composting process and odour emission

    The objectives of this paper are to determine the effectiveness of bioadditive in the form of yeasts and zeolite in reducing odour and ammonia emissions during composting and to assess its effects on the process. Two series of experiments were conducted. The higher dosage treatments reached thermophilic temperatures sooner and the high temperatures stayed longer. The application of bioadditive at ...

  • Effect of composting on sludge contaminated with heavy metals from three different tannery streams and their bioavailability to plants

    This research was conducted to study the influence of composting on tannery sludge contaminated by Cr, Cd, Zn, Cu, and Ni. Composting of sludge streams was performed in three different piles for 60 days. The results showed that the total concentration of heavy metals was increased with composting, except in the TT-3 sample where the concentrations of Cd, Cu, and Ni did not increase. The ...

  • Devontalk - Composting in schools in Devon

    Do you know what London's 02 Arena and Okehampton College have in common? It's something called Big Hanna, a huge shiny composter that turns all their food waste into compost. Big Hanna arrived in Okehampton last year and immediately made her presence felt because someone had to look after her and feed her regularly. That someone is Okehampton-born and bred Gary Drew, who went to the college ...

  • Effects of composting on removal of nitrogen, phosphorus, and potassium

    A six month study evaluated composting affects on nitrogen (N), phosphorus (P), and potassium (K) leaching from hardwood and furniture sawdust amended with 20% and 30% chicken litter. Toxicity Characteristic Leaching Procedure (TCLP) was obtained from substrates. Moisture was provided through precipitation, and the substrate was aerated once or twice per week, depending on the amount of rainfall. ...

  • Nitrogen and sulphur transformations in composts containing chicken feathers

    Chicken feathers composted with pine bark and rye straw are subject to intensive mineralisation and biotransformation with efflux of water-soluble components: N-NH4, N-NO3 and S-SO4. The content of N-NH4, N-NO3 and S-SO4 in water extracts of the studied composts was positively correlated with the time of composting. The release of those components reached a maximum after 15 weeks of composting ...
