|Methods for quantifying gaseous emissions from full-scale windrow composting of garden waste|
T.H. Christensen, Charlotte Scheutz
Two different methods for quantifying gaseous emissions have been used and assessed in this study. These are small scale point measurement methods and they were used at a composting facility treating garden waste: a flux chamber method and a dynamic funnel method. The present paper describes the generation of GHGs and their spatial and temporal distribution during composting. In addition the emissions of these GHGs have been quantified and related to the degraded mass of carbon and nitrogen respectively.

|Fecal indicators and pathogenic bacteria in USA market ready green composts and relationship to management parameters|
William Fisher Brinton,
Composting has emerged recently as a strategy for recycling waste organic matter as an alternative to landfilling andincineration. Originally regarded as a fertility management tool for organic farming (Mukherjee et al. 2004) it was adapted by developed nations in the 1950âs to tackle municipal solid waste (MSW) with poor results (Hickman, 2001). Dramatic growth in composting has come about recently in Europe and N. America as a means to attain legislated recycling and landfill reduction mandates (USEPA 1992). Bulky components of waste such as woody yard trimmings, grass clippings and food scraps, which may occupy up to 45% of the waste stream, are obvious targets. At least 22 states in America have imposed restrictions or bans on accumulation of yard trimmings in landfills. Compost recycling has grown with the expectation of absence of significant risk to society (Farrel 1992, USEPA 1992). Studies in the 1960âs indicated thermal inactivation of numerous pathogens from the sustained biological heating of composts (Wiley 1969). The USEPA sponsored studies on pathogen reduction in sewage sludge composting, and subsequently drafted the findings into regulation as the EPA-503 rule (Farrel, 1992). Since then, this 503 Rule has been widely applied to all types of recycled organic matter (ROM).

In this context, biological treatments as composting are encouraged because they allow an agronomic reuse of the organic matter contained in biodegradable organic wastes.
|Respiration and microbial community succession as compost stability indicators|

Although a large variety of stability indexes has been proposed in the literature and some have been adopted in national regulations, the question of identifying parameters effectively reflecting the stabilisation process of organic matter during composting still remains.
