Landfill Engineering and Environmental Conflicts

Fri, 03 Jul 2009 01:35:03 +0000

Landfill engineers are increasingly preoccupied with building landfills which will capture as much landfill gas as possible and use that gas optimally to generate renewable energy. However, this very engineering holds dangers for the environment around a landfill, with raised leachate levels, and extra stress on landfill lining membranes.

US EPA Landfill Capping

Fri, 15 May 2009 23:00:59 +0000

Landfill Capping is the most widespread type of remediation since it is in general less pricey than other technologies and actually manages the human being and environmental risks allied with a remediation place. In this article we provide the basics of capping according to the US EPA.

Landfill Reclamation

Landfill reclamation is a technique which can be very beneficial and profitable to developers in certain cases. To reclaim the land of an old tip returns it to normal use and the land can then be used for housing and factories etc. Read more about Landfill Reclamation in this article now!

How to Do Landfill CQA Up to the Start of the Construction Works

Sat, 20 Dec 2008 01:28:41 +0000

Landfill CQA Actions up to the Start of Construction Once the landfill design engineer has completed the landfill design and the specification has been substantially completed, it is possible to write the landfill Construction Quality Assurance (CQA) Plan, which the construction contractor will then be required to follow, and which will once completed be reported upon [...]

Why Landfill Construction Quality Assurance is so Important to the Installation of Landfill Geomembrane Liners

Tue, 16 Dec 2008 22:04:48 +0000

Landfills nowadays each contain huge amounts of organic materials and hold a huge potential to pollute the local groundwater for generations in the containment systems upon which their design is based fail to function as intended. The engineering of a landfill is no different to other engineered structures, in fact in many ways, especially due to [...]

How to Design a Permanent Geological Exposure in a Landfill

Sun, 14 Dec 2008 20:21:05 +0000

One of the most common locations for landfills are worked out quarries and quarries suitable for landfill are an increasingly valuable resource for this reason. In a growing number of cases suitable sites include rare geological exposures of mineral bearing rock, or strata of regional importance which need to be kept exposed after landfilling for educational [...]

Top Landfill Development Contractors (UK)

Tue, 28 Oct 2008 22:52:01 +0000

The closest you can get to a list of the top contractors doing Construction Quality Control (CQC) work on landfill developments (basal development and capping/restoration) is probably the following list. New Civil eEngineer Magazine, which is the weekly news magazine of the Chartered Institution of Civil Engineers, provides through eMapInform an annual contractor listing and ranking [...]

The Use of Landfill Tyre Drainage Layers and Their Hydraulic Capability Under Load

Sat, 16 Aug 2008 02:09:07 +0000

Leachate drainage layers are necessary in most waste landfill sites to minimise the accumulation of leachate within the site and they reduce the risk of contamination of surrounding ground and groundwater. A cheaper and environmentally preferable option is be the use of scrap vehicle tyres, but is their use permissible and what happens to them [...]

Dense Asphaltic Concrete as a Landfill Lining

Sun, 13 Jul 2008 01:24:58 +0000

Dense Asphaltic Concrete has been as a Landfill Lining membrane material for many years and although it is not commonly seen in the UK, it is used much more often in Europe, and particularly in Germany. The Dense Asphaltic Concrete is formulated in a manner which ensures both very low permeability and possibly as low as 1 x [...]

Dense Asphaltic Concrete Can be an Alternative to HDPE Liners

Fri, 11 Jul 2008 23:57:45 +0000

Dense Asphaltic Concrete can be an extremely versatile product, suitable for many types of applications. The ancient civilizations of Egypt, Babylon and Assyria all used bituminous lining materials and mortars for waterproofing and building, some more than 5,000 years ago, and many examples of their work remains intact even today. More recently with the advances in hydraulic technology, asphalt [...]
