  • 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 ...

  • 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 ...

  • Compost Dried Primary Sludge – A Renewable Energy Source?

    Abstract Napier is a city of almost 60,000 population on the east coast of the North Island, New Zealand. Napier City Council planned to upgrade its Awatoto Wastewater Milliscreening (0.75mm aperture) plant to advanced primary treatment (APT) and ultraviolet disinfection to improve the quality of discharge to the ocean through the existing 1600m long outfall into Hawke Bay. The APT plant ...

  • Influence of different co-substrates biochemical composition on raw sludge co-composting

    The influence of biochemical composition of different co-substrates added to raw sludge during co-composting process was studied. The physical properties of the composting mass and theirinfluence on the biological activity were also investigated. Three treatments composed of mixtures of raw sludge and co-substrate (commercial fats, protein, and cellulose) were carried out and compared to a ...


  • Cattail plants’ Biomass as a bulking agent in sewage Sludge composting and the effect of the produced Compost on cattail plants’ Growth

    In every Greek island there is at least one town with more than 20,000 inhabitants. Several smaller towns and villages range from a few hundreds to a few thousands in population. Usually in the larger towns there are sewage treatment facilities providing at least secondary treatment of wastewater. In most cases the effluent produced is drained to the sea and the sludge is dumped in landfills. In ...

  • Phosphorus And Compost Use Dynamics

    Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources. Phosphorus is one of the 16 essential plant nutrients, and is considered one of the three major plant nutrients (along with nitrogen and potassium). Phosphorus is not only important in root development, but ...

  • Food Residuals Composting in the U.S.

    For many years, the public sector has been at the forefront of the developing composting industry. For example, when biosolids composting first got started, it was the sanitation departments of municipalities and local sanitary authorities pushing projects. With yard trimmings composting, municipalities and counties were the primary entities developing programs. Even the fledgling steps of solid ...

  • 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 ...

  • Oxygen Uptake of Soil and Compost Samples

    Oxygen Uptake of Soil and Compost Samples The Challenge AER-200 aerobic/anaerobic respirometer is ideally suited to determine in-situ rates of oxygen uptake in soil or compost samples – as may occur in the upper layers of soil under natural atmospheric conditions or in mixed compost reactors. This objective is accomplished by using a double-column reactor configuration as illustrated in Figure ...

  • Quality of compost: the experience of veneto region

    The Regional Administration of Veneto Region (Italy) established in 1991 the rules for authorisation of composting plants for treatment of pre-selected organic wastes, including urban sludges, organic fraction of municipal solid wastes and animal manure. Also chemical composition of compost were regulated (Table 1). Some composting plants started working in 1994; at the moment seven farms are ...

  • Composting on Maui hits its stride

    The Hawaiian island of Maui - a vacation destination for more than 2.2 million people each year - has a year-round growing season that yields a massive stream of green waste from nonstop cutting, trimming and pruning. For years, the resultant trimmings were simply landfilled along with the 500 tons/day of trash. One company, however, decided to turn that tide and has been aggressively taking in ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
