RNA-based high-throughput sequencing is a valuable tool in the discernment of implication metabolically active bacteria during composting. In this study, “alperujo” composting was used as microbial model for elucidation structure-function relationships with physicochemical transformation organic matter. DNA and RNA, subsequently retrotranscribed into cDNA, were isolated at mesophilic, thermophi...

The management of Municipal Solid Waste (MSW) in Nigeria and most developing countries has remained a major public health challenge, thus creating the need for reliable and environmentally-acceptable alternatives. This study focuses on composting assessment as a viable recovery alternative for MSW in six States of Southwest Nigeria, namely: Ekiti, Osun, Ondo, Ogun, Oyo, and Lagos. Extensive lit...

This chapter describes the methodology used in EPA's Waste Reduction Model (WARM) to estimate streamlined life-cycle greenhouse gas (GHG) emission factors for yard trimmings and food scraps beginning at the point of waste generation. The WARM GHG emission factors are used to compare the net emissions associated with these two organic material types in the following three materials management op...

This paper presents preliminary results from a year-long indoor bioaerosol monitoring performed in three working environments of a municipal composting facility treating green and organic waste. Composting, whereby organic matter is stabilized through aerobic decomposition, requires aeration, causing the dispersion of microbial particles (microorganisms and associated toxins). Waste can, theref...

This paper aims to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge and green algae regarding their biodegradability, their stabilization kinetics and their temperature rise during composting. Three experiments in lab-scale pilots (300 L) were performed for each waste, each one under a constant aeration rate. The aeration rates applied were comprised between ...

Due to economic growth Greece has experienced a large amount of waste generation during the last twenty years. Landfill has been the predominant waste treatment method which applied so far in the country. A large portion about 90% of the refuse is disposed in Sanitary Landfills and open dumps. European Union concerns for the human health, as well as the environment impose a specific framework f...

Materials and Methods The poultry industry in India has undergone a paradigm shift, from backyard venture before the 1960s to vibrant intensive agribusiness, growing at around 8 to 10% annually over the last decade. This fast growing industry is currently facing issues regarding waste management. Accumulation of large amount of wastes is one of the major problems, posing serious challenge to th...

1 This paper aims to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge 2 and green algae regarding their biodegradability, their stabilization kinetics and their temperature rise during 3 composting. Three experiments in lab-scale pilots (300L) were performed for each waste, each one under a 4 constant aeration rate. The aeration rates applied were comprised b...

The benefits of biodegradable and compostable (B&C) products are attained when the organic waste (OW) is composted. B&C products may improve the management of OW, so that greater and cleaner OW flows can be collected and composted. In this paper we show the case of the catering sector as an example of this. Disposable tableware is usually distributed at fast food restaurants and town festivals....

Pathogen contamination of waterways is a serious concern in dairy farming areas where livestock waste is applied to agricultural fields. As an alternative, a biodrying composting system dries collected livestock waste, reduces the strong odors, and has been proposed as a means of reducing, and even eliminating pathogens present in the waste. Therefore, the survival of pathogens in a biodrying c...
