  • Composting

    Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...

  • Aerobic Composting 101

    If you have recently purchased a compost tumbler bin, let me be the first to say congratulations! You’ve just taken the first step toward aerobic composting. What is aerobic composting, you ask, and why is it so great? In this article, we’ll explain how aerobic composting works and what you need to do to get started. There are two main types of composting, aerobic and anaerobic. ...

  • Ohio supermarket composting

    State and grocery chain commitment lead to successful food waste diversion pilot that could motivate others to replicate program. IN JULY 2008, the Kroger supermarket chain decided to expand its active role in the community to include an environmental element. The company’s first food scrap composting program was rolled out in 24 Ohio stores. In just four months, more than 650 tons of food waste ...

  • Troubleshooting the Compost Pile

    While composting is a biological process, we as composters must provide the microorganisms that do the work with the conditions they need to do their job. If there is a problem with the system, then look at it from the point of view of the microbe. What does that microbe need to function, and why isn’t it functioning correctly? Microorganisms need a source of energy organic feedstocks to feed on ...

  • Decolorization of paper mill effluents with disimilar characteristics using anaerobic composting

    Currently, there are no national standards for color limits in pulp and paper mill  wastewaters effluents. In some cases, there are regional or State stream standards based on the receiving waters. Decolorization of this industry wastewater is getting higher concerns due to possible regulations to the color of the discharge effluents. The sustainability of color removal and the degree and ...

  • Why home composting is so great!

    Have you heard of composting, but just aren’t sure what it means? Not sure why how compost can benefit you? If you haven’t started composting at home yet, now is the time! Home composting is more than just a growing trend among gardeners, it’s a great way to recycle your kitchen scraps and yard refuse into something you can use-compost!

  • Monitoring Moisture In Composting Systems

    Monitoring Moisture In Composting Systems IF YOU SQUEEZE a handful of material and water drips or trickles out, it is the right moisture content for composting.” This bit of hands-on wisdom comes from the proverbial squeeze-test for evaluating moisture in composting piles. It has been uttered by Master Gardeners and other composting educators for many years as a tool for determining, and ...

  • Composting and biogasification for senna pod waste stabilization

    A medical factory in Finland extracts sennocid from pods of a senna plant with a solvent containing methanol and water. Sennocid is the active compound in some constipation medicines (Otavan Iso Kasvitietosanankirja, 1981). The extraction process produces 50 m3 of pod waste weekly. In 1998, 757 tons of pod waste was produced. The water and methanol contents of the waste are approximately 25 w/w-% ...

  • Introduction of composted digestates in agriculture

    Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...

  • Composting in flanders: the vlaco experience

    Currently, the Flanders waste policy is based on the so-called ‘ladder of Lansink’. Six aerobic composting and one anaerobic digestion plant are operational for the treatment of biowaste. Some new composting plants are foreseen for 1999 and/or 2000. Composting retention time varies from 10 to 15 weeks. Green waste is treated in 15 open air composting plants. With respect to the use of compost ...

  • Evaluating the potential of an electronic nose for detecting the onset of anaerobic conditions during composting

    Most bad odours in composting plants are formed under anaerobic conditions and often they could be avoided if detected early enough. In this project an electronic nose was used to evaluate the odours produced during a composting process at bench scale. The electronic nose consists of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system ...

  • Composting infrastructure trends in the UK

    The European Union's Landfill Directive, which restricts landfilling of biodegradable waste, has made it necessary to develop alternative infrastructures to manage the organic fraction of the solid waste stream. In the United Kingdom, the Landfill Directive has created demand for composting facilities that take source separated organics (SSO), and for anaerobic digestion. Infrastructure also is ...

  • Food composting infrastructure

    From 1995 to 2000, BioCycle published an annual national survey of food waste composting projects in the United States. Since then, we have continued to track food waste composting activity, and in 2007 launched www.findacomposter.com, a publicly searchable data base that lists many sites in the U.S. that receive municipal, commercial, institutional and industrial food waste ...

  • 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 ...

  • A new Technology for Composting: Suction Aeration for Opening Composting Works

    Cost-efficient solution for smell emission reduction The enormous waste quantities that are produced day by day are one of the most difficult problems for the economy as such, for cities and communities and for private households. Storage capacities for waste are scarce everywhere. Therefore solutions of all kinds that reduce waste quantities or recycle waste materials to be reused in the ...

  • Commercial composting provides food for thought

    The retail sector and food manufacturers produce a mountain of waste but, unlike householders, they cannot simply throw it in the compost and wait for it to rot down. The Compost Association told edie about the obstacles in the way of recycling waste from the commercial sector. Compared to household domestic waste, biodegradable matter from the retail and catering sector represents only a small ...

  • 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 ...
