Reduce Emissions

Emission of methane from landfills due to anaerobic decomposition of organic material is oneof the most important environmental concerns with regards to solid waste management. Thisis due to the amount of methane released from landfills globally and the relatively high globalwarming potential of methane. An approach to reduce emissions is to improve conditions forbiological oxidation of methane in the top cover using engineered biocovers.A demonstration project was initiated at the Technical University of Denmark under the EULife Environment program, where this technology is applied in full scale at section I on Fakselandfill in Denmark. Construction of the full scale biocover at the test site was completed attime of writing.The main project objective was to document the construction and efficiency of the system.The project actions consist of a logical order of tasks performed in able to meet the objectivesof the project. At first the landfill was characterized. Expected landfill gas production wasestimated based upon the collected data using models. Then, a baseline study was performed,consisting of an evaluation of the spatial variability in methane emission at the site. The totalmethane emission from the landfill was measured by use of a tracer technique.Mixtures of locally available soils and organic waste residuals were tested by laboratory batchand column experiments. A cover improvement plan included details on material additions toselected areas of the landfill, maintenance plans of the total landfill cover. A plan formonitoring performance was setup. The emissions after the cover improvement will becompared to the emissions obtained during the baseline study. Scenarios for other landfillswill be calculated based on the experiences obtained from the studied landfill.

The present experiment was a preliminary attempt to use the psychophysical scaling methods of magnitude estimation and cross-modal matching to investigate suprathreshold judgments of lingual vibrotactile and auditory sensation magnitudes for 20 normal young adult subjects. A 250-Hz lingual vibrotactile stimulus and a 1000-Hz binaural auditory stimulus were employed. To obtain judgments for nonoral vibrotactile sensory magnitudes, the thenar eminence of the hand was also employed as a test site for 5 additional subjects. Eight stimulus intensities were presented during all experimental tasks. The results showed that the slopes of the log-log vibrotactile magnitude estimation functions decreased at higher stimulus intensity levels for both test sites. Auditory magnitude estimation functions were relatively constant throughout the stimulus range. Cross-modal matching functions for the two stimuli generally agreed with functions predicted from the magnitude estimation data, except when subjects adjusted vibration on the tongue to match auditory stimulus intensities. The results suggested that the methods of magnitude estimation and cross-modal matching may be useful for studying sensory processing in the speech production system. However, systematic investigation of response biases associated with vibrotactile-auditory psychophysical scaling tasks appears to be a prerequisite.
