  • 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 ...

  • The control of the process and compost quality

    The European Commission has adopted a new proposal on landfill whose objective it is to reduce the impact of waste disposal on the environment. The new directive introduces a series of new elements and provides for a number of safeguards with respect to both existing and new landfills. Disposal of waste is the option of last resort in the hierarchy of waste management principles; the Commission ...

  • Composting of washed Ulva reticulata seaweed: process parameter variations and compost quality

    Co–composting process of unwashed (Run A) and washed (Run B) seaweed Ulva reticulata with bagasse and broiler litter was studied. Peak temperatures of 48.9°C and 55.2°C were recorded for Runs A and B, respectively. For Run A, the starting wet bulk density was 43.31 kgm–3 and increased by 5.2 times on day 23. Net biodegradable Volatile Solid (VS) reductions were 2.19 and 11.44% ...

  • Homogenous mixing for shortening of composting processes - Case Study

    Various treatment processes are used today for manufacturing compost, of which two are of particular interest in terms of mixing and treatment technology. They are open composting and container composting. In both cases e.g. sewage sludge (wet and dry), chopped paper, loppings, green waste, and sawdust are pre-mixed with the possible addition of small amounts of active substances. The task of ...

  • Cover-all building ideal for composting process

    Hy-Line International is a multi-million dollar company whose primary purpose is the sole production, multiplication and distribution of leghorn genetics.  At its Iowa facility in Dallas Center, Hy-Line chose to handle its hatchery by-product in a cost effective manner by combining it with field by-products, such as corn stocks and chicken manure, to create a compost product for ...


  • Odour emissions from MSW composting process steps

    This study brought to the definition and the calculation of Odour Emission Factors (OEFs), which enable the estimation of odour emissions from a composting plant by relating the quantity of odour emitted to the atmosphere to a given associated activity. The results show that the aerobic biological treatment has the highest odour impact, with an OEF of 1.4 ? 108 ouE t−1. Moreover, the efficiency ...

  • Effect of covering composting piles with mature compost on ammonia emission and microbial community structure of composting process

    Received for publication February 14, 2008. To control ammonia (NH3) volatilization from the dairy cattle (Bos taurus) manure composting process, a compost pile was covered with mature compost and the gas emissions evaluated using the dynamic chamber system. The peak of NH3 volatilization observed immediately after piling up of the compost was reduced from 196 to 62 mg/m3 by covering the compost ...

  • Compost Express—How to Make Compost in Half the Time

    Fall is a terrific time for making compost, partly because leaves—which have a way of coming down this time of year—are a fantastic source of soil enriching nutrients. And since you probably plan to remove all those leaves from your lawn anyway, recycling them into your compost pile is a win-win proposition. Since leaves need to break down in order to integrate with the ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Compost Users Forum: Compost Marketing Trends In The U.S.

    “We know there are limiting factors in this sector,” acknowledges Hans Van Dusen, who is on the contract implementation staff for Seattle Public Utilities. “Transient populations as well as space in downtown and older buildings are problematic, but multifamily recycling has emerged as a priority for the city.” Seattle has taken a number of steps to make its program more user friendly and flexible ...

  • 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 ...
