For economic, agricultural, and environmental reasons, composting is frequently used for organic waste recycling. One approach to limiting the potential risk from bacterial food-borne illnesses is to ensure that soil amendments and organic fertilizers are disinfected. However, more knowledge concerning the microbiological safety of composted substrates other than sludge and manure is necessary....

Environmental policies at the European and global level support the diversion of wastes from landfills for their treatment in different facilities. Organic waste is mainly treated or valorized through composting, anaerobic digestion or a combination of both treatments. Thus, there are an increasing number of waste treatment plants using this type of biological treatment. During waste handling a...

Composting is clearly reported as one of the most effective technique to transform organic wastes into an interesting resource, useful to improve soil characteristics and playing a potential role in reducing greenhouse gases, due to its high content in stable organic matter (Favoino and Hogg, 2008). However, its agronomical properties are dependent on several factors, which pollutant contents b...

To ensure quick and uniform aerobic stabilization of biowaste through domestic composting and to prevent malodorous emissions, two modifications were made to a conventional steel barrel composter by: (1) providing 0.0125 m diameter openings throughout the sides and (2) placing a 0.0254 m diameter perforated polyvinyl chloride (PVC) pipe in the middle portion of the barrel. The volume of compost...

In this paper we investigate the economic and environmental efficiency of charities and NGO’s “rescuing” food waste, using a 2008 case study of food rescue organisations in Australia. We quantify the tonnages, costs, and environmental impact of food rescued, and then compare food rescue to other food waste disposal methods composting and landfill. To our knowledge this is the first manuscript t...

Exposure to bioaerosols in the occupational environment is associated with a wide range of adverse health effects. Composting is biological decomposition of organic waste material which necessarily leads to proliferation of microorganisms with in the composting substrate, it is potential for these microorganisms to become airborne as the compost is being turned and screened. Exposure to bioaero...

Composting is a good recycling method to fully utilise all the organic wastes present in kitchen waste due to its high nutritious matter within the waste. In this present study, the optimised mixture proportions of kitchen waste containing vegetable scraps (V), fish processing waste (F) and newspaper (N) or onion peels (O) were determined by applying the simplex-centroid mixture design method t...

Government policy requires that valuable resources should be recovered and recycled from biodegradable waste. A successful and growing organics recycling industry delivers this policy with composting being one of the principal technologies deployed to process suitable feedstock such as garden and food waste. Composting inevitably generates bioaerosols – particulate matter comprising cells or ce...

A pollutant solid material called "alperujo" (AL), which is the main by-product from the Spanish olive oil industry, was composted with a cotton waste as bulking agent, and the compost obtained (ALC) was compared with a cattle manure (CM) and a sewage sludge compost (SSC) for use as organic amendment on a calcareous soil. The experiment was conducted with a commercial pepper crop in a greenhous...
