ARGUS (2000) The behaviour of PVC in landfill. Final report February 2000. Report prepared for the European Commission Environment Directorate (DGXI.E.3) by ARGUS (Germany) in association with Professor Spillmann (University of Rostook, Germany), Carl Bro (Denmark), and Sigma Plan (Greeoe) (http //ec.europa.eu/environment/waste/studies/pve/landfill.pdf). 

Continuous daily addition of the waste volume corresponding to each R.T. or the volume established in the mixed waste studies. 

Except in case of the anaerobic digestion of poultry waste, methane production decreases as retention time is reduced. This is a result of the substrate being exposed for less time to the action of anaerobic bacteria. With the poultry waste, it was noted that methane production increased as the retention time was reduced. Also the methane production in the three retention times studies was much higher than that reached in the mixed wastes study when the retention time was greater than 30 days. 

The main difference is in the composition of the substrate In the retention time study, the volatile solids value varied between 3, 5 and 7 while in the mixed wastes study it varied between 3, 6 and 4, 2. 

The percentage of methane in the biogas was 60.1% for a retention time of 30 days and 56.8% for a similar retention time in the mixed waste study.

The first step in any toxic waste study is to determine what toxic materials are present and in what amounts. Since most toxic waste situations involve the dumping of diverse materials, problems of expensive technical methodology can be formidable. However, without an adequate inventory of the... 

The limitations of these observations can be described in terms of the general problems associated with such toxic waste studies. The health outcome of concern (cancer, specifically childhood leukemia) is a relatively rare disease. The toxic chemical exposure of particular persons having these diseases could not be directly documented, since the organic chemicals found in well water were transient. Therefore, no means were available for linking particular leukemia cases to particular toxic substances. For the present, then, we are left with an apparent leukemia case cluster and no good evidence for associating cases with the striking environmental toxic waste problems clearly present in the town. 

Variograms can be calculated from irregularly spaced data. However, the plots can be misleading if not interpreted with care, so this case is not addressed in this introductory primer. Variograms can also be plotted with a distance lag between samples. Examples include applications in geostatistics and environmental solid waste studies (Gressie, 1993). 

How reactive are incineration products of municipal solid waste Studies conducted by Baccini and colleagues (1993) have shown that, under long-term considerations, even products such as incineration bottom ash are not really inert. After the release of chloride and sulfate, two developments can be distinguished. First, part of the calcium content, which was formerly...

Each year, the average US citizen throws away 70 pounds of clothing and textiles. According to the 2012 Federal Municipal Waste Study conducted by the ERA, 21.8million tons of textile products are discarded each year with only 3.5million tons of postconsumer textile waste (PCTW) recycled, but this comprises only 8.7% of the municipal solid waste generation. Thus, 84% of textile and apparel consumption is sent to US landfills (ERA, 2012). By 2019, the amount of PCTW generated waste is projected to increase by 40%, primarily due to increased consumption of fast-fashion apparel.

Compared to the investigations described above for SLMs in processing actinides from spent fuel wastes, studies devoted to ELMs are very limited. ELM transport of U(VI) from a solution which was 0.01 M in nitric acid and 2 M in sodium chloride with an emulsion of 2.5 M phosphoric acid in 0.1 M DEHPA-dodecane is practically quantitative (Table 9) and equivalent to 66 stages of extraction with the DEHPA in dodecane (55).
