Inactivation kinetics of indicator microorganisms during urea treatment for sanitizing finished compost from composting toilet
This study aimed at estimating the sanitizing effectiveness of urea treatment by studying the inactivation kinetics of selected indicator microorganisms. Finished composts from a composting toilet were inoculated with indicator microorganisms and subjected to different urea concentrations (0.5–2% w/w) and temperatures (22, 32 and 42°C). The inactivation kinetics parameters were determined in ...

Caledon Compost Facility - Case Study
About the Project The Regional composting facilities for organics, food and yard waste are located at the Peel Integrated Waste Management Facility and the Caledon Public Waste and Recycling Depot. The program does not replace backyard composting, but enhances it by allowing residents to compost materials that can’t be put in their backyard composter. Currently 9,000 tonnes/year ...

Removal of 2-methylisoborneol from aqueous solution by cattle manure compost (CMC) derived activated carbons
The objective of this study is the synthesis of activated carbon derived from cattle manure compost (CMC) causing environmental problems using zinc chloride (ZnCl2) activation and to examine the suitability and performance of the prepared activated carbon (PAC) in removing 2-methylisoborneol (2-MIB) from aqueous solution. The influence of ZnCl2/CMC ratios and outgassing from the PACs on the ...

Kinetic study of compost liquor nitrification
This study is a first kinetic approach about the compost liquor treatment by activated sludge. This industrial wastewater is highly loaded in organic and nitrogen compounds (COD≈12,000 mg L−1 and NH4+-N≈4,000 mg L−1). The possibility of its treatment in an urban WWTP is studied measuring ammonia oxidation rate with non-acclimated sludge to the industrial effluent. Compost liquor appears as an ...

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 ...

Slaughterhouse carcass waste composting case study
Slaughterhouse waste was treated with BactiDomus Technology compost accelerator to monitor the effects of the treatment against untreated waste. The goal of the project is to increase the efficiency of the composting process to reduce the total time needed to turn the waste into compost. Two separate bins of waste were treated with BactiDomus Technology compost accelerator, the first on August ...

Ammonia Reduction & Reduced Beetle Larvae with MICROBE-LIFT® Technology in Poultry Composting in Honduras - Farm Waste Management
Lazarus & Lazarus, a technology-based construction firm in Honduras, contacted a distributor of Ecological Laboratories to explore technology to improve their poultry litter processing. Ecological Laboratories’ technologists devised a test protocol using MICROBE-LIFT® technology conducted at an experimental poultry farm. This farm is utilized to evaluate new technology to optimize ...

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 ...

Influence of temperature during the initial phase of Composting on biological activity and emission of Ammonia and dinitrogen oxide
Composting is a robust and cheap biological treatment method useful for all solid biodegradable waste. The performance of composting can vary substantially depending on managing conditions such as oxygen supply and compost temperature. Oxygen and temperature affects the rate of degradation and may also influence emission of NH3 and N2O. The gaseous N losses during composting from organic ...

Odour pollution problems caused by composting activities in flanders: current situation and abatement strategies
In Flanders, garden fruit and vegetable (GFV) waste is selectively collected and composted in 7 composting plants, in six of which aerobic indoor composting is used. In the seventh plant waste is anaerobically digested first followed by an aerobic post-treatment. The total amount of waste composted was about 275 000 tons in 1997 (OVAM, 1999). The nominal capacity of the composting plants varies ...

Compost stability: a comparative evaluation of respirometric techniques
The new Paradigm in waste management promotes attitudes and processes that conserve resources and reduce pollution. Under this philosophy, organic waste is increasingly recognised as a recyclable material, a useful resource, making composting one of the key elements of modern waste management. As the composting industry is expanding rapidly there is a growing need for a simple, fast, relatively ...

Composting in the Subarctic – Operations
The Actium compost drums are used in a variety of climates. In the tropical and subtropical climates, the composter is used year-round. In temperate climates, the Actium Batch Compost Drum can be used year-round because the drum is insulated. However, the decaying process can be slowed where winter temperatures are below freezing for a prolonged period. There are two approaches to maintain hot ...

Waste Management a Problem & Organic Waste Composters a Solution
What would it be like to wake up one day to a planet free of trash and other debris? You can know that this vision is a theory based on your present knowledge of the scenario. Because we’re still more concerned with increasing production than reducing or simply controlling the waste that results, we’ve created this situation. Try to imagine a world populated ...

How to speed up composting
How to Speed up Composting Composting is a natural process. You can say it’s the most important recycling process in the ecosystem. Every living thing on the planet eventually dies and breaks down into soil to help new plant life (and, subsequently, every other living thing) flourish. By learning about the key factors in making fast compost we can begin making our own compost piles more ...

Combining primary collection with decentralised composting - a solution?
The environmental problems of urban areas extend over a wide range of spatial scales; i.e., the household, the place of work, the neighbourhood, the city, the wider region, and the world. In rapidly growing cities of the developing world, urban solid waste management (SWM) is currently regarded as one of the most immediate and serious problems faced by urban governments. Inadequate or unavailable ...

Composting: Art and science of organic waste conversion to a valuable soil resource
Raw organic materials such as grass clippings and manure are transformed into stable soil-like humic compounds through decomposition in the composting process. Composting is an age-old practice found in various settings, ranging from domestic to industrial. Compost maker machine is becoming an increasingly practical method of organic waste disposal when landfills reach capacity ...
