BACKGROUND The migratory patterns of animals are changing in response to global environmental change with many species forming resident populations in areas where they were once migratory. The white stork (Ciconia ciconia) was wholly migratory in Europe but recently guaranteed, year-round food from landfill sites has facilitated the establishment of resident populations in Iberia. In this study...

Sampling and analysis of leachate from Bhalaswa landfill and groundwater samples from nearby locations, clearly indicated the likely contamination of groundwater due to landfill leachate. The results of simulation studies carried out for the migration of Chloride from landfill shows that the simulation results are in consonance with the observed concentration of Chloride in the vicinity of land...

An autonomous environmental monitoring system (Smart Landfill) has been constructed for the quantitative measurement of the components of landfill gas found at borehole wells at the perimeter of landfill sites. The main components of landfill gas are the greenhouse gases, methane and carbon dioxide and have been monitored in the range 0-5 % volume. This monitoring system has not only been teste...

EXECUTIVE SUMMARY: Terms as ‘landfill stability’ and ‘final storage quality’ are very often used in discussions about sustainable landfill and groundwater protection at landfills. Internationally accepted definitions of these terms are not available. Consequently there is also no shared notion of sustainable landfill. In a Dutch sustainable landfill project it was proposed that: ‘a landfill is ...

Shredded green wastes were composted in windrows, at the Harewood Whin landfill, near the city of York, in West Yorkshire, UK. Landfill leachate were added twice during the second and fourth week of the process in two piles. One pile was turned once every week for eight weeks and the other was turned twice, during the same period. Each time approximately, 2 m3 of leachate was added, into each p...

The time-series topography change of a landfill site before its failure has rarely been surveyed in detail. However, this information is important for both landfill management and early warning of landslides. Here, we take the 2015 Shenzhen landslide as an example, and we use the radar shape-from-shading (SFS) technique to retrieve time-series digital elevation models of the landfill. The resul...

Relandfill activity, which means digging up landfill waste and recovering resources, can remove the material having been landfilled, and will free up the land to be reused as new landfill space. We have extended the WIO model for environmental assessment including re-landfill activity. As a part of this work, we have estimated landfill consumption and CO2 emission based on 4 kinds of scenarios ...

Surface spraying, horizontal trenches, and vertical wells are the most common leachate recirculation system used at landfills in engineering practice. In order to quantify efficiency of three aforementioned systems, a hydro–biochem–mechanical-coupled model was developed present work, which can describe hydrodynamic biochemical behaviors food-waste-rich landfills. A typical landfill cell modeled...

SUMMARY: Investigations into landfill simulation reactors and a full scale landfills are used for predicting emissions from municipal solid waste landfills. In the present study the water flow and solute transport through a landfill simulation reactor and a full scale landfill (using the same waste) has been investigated. The results indicate that, due to preferential flow pathways the water fl...
