Optimization of Experimental Biomethanation Applied to Poultry Droppings for Better Energy Valorization

Optimization of Experimental Biomethanation Applied to Poultry Droppings for Better Energy Valorization



Ghariani. I, Najar. T



The fight against climate change is first and foremost
passed by the reduction of greenhouse gases (GHG). Mainly in the form
of methane CH4, the GHGs emitted by the waste originate from the
decomposition of organic matter which is more commonly known as
Anaerobic Digestion (AD) or Biomethanation. Livestock manure is one of
the major hazards to the environment and human health due to the
nuisances and pollution generated. The present study consists of
optimizing the methane fermentation applied to poultry droppings. This
optimization focuses on the daily monitoring of experimental digesters,
on the physico-chemical characterization of the inputs used and on the
study of the effect of temperature and inoculum changes on the daily
production of biogas and its composition (CH4, CO2 and H2S). The main
results show, on the one hand, that the stability of the DA process
after initial filling depends on experimental conditions, the general
characteristics of the anaerobic digester, the initial biomass activity
and the nature of the introduced inoculum. On the other hand, the
production of biogas is better at a temperature of 35°C than at a
temperature of 55°C and the addition of the inoculum has improved the
production of biogas and the CH4 content, especially the use Of liquid
poultry digestate.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
