Why Every Landfill Liner Leaks But Not All Leakage Matters

Landfill liner leaks are endemic. A small amount escapes from composite landfill lining systems which include both 1 metre thick a clay layer, and a clay liner loses water/ leachate according to its permeability and the head of pressure of leachate over it. That is despite applying stringent design and operational requirements for landfills, landfills continue […]

Zero Waste and UK Recycling Progress

Landfills vary immensely, but even the most recently developed are not considered to provide a sustainable way of getting rid of rubbish.  They can cause pollution, and certainly hold the potential to do so. Very few of us want to live near to them, and the methane gas produced by them is a major contributor […]

DSEAR United Kingdom article

Landfill Sites and the DSEA Regulations (DSEAR – UK)

Here is an explanation of the requirements of the DSEA Regulations and what they mean for landfill site owners and operators. All landfill owners (and by delegation their operators) fall under this regulation, and must act in order to comply with Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) which have been in force since July 2006. DSEAR – […]

The Trading of Carbon wrt Landfills

Carbon Credit Trading and Landfills

It’s Methane that makes Landfill and Carbon Credit Trading so interconnected. Methane is the second most prevalent greenhouse gas after carbon dioxide, is emitted in large quantities from modern engineered landfills unless it is collected and flared (burnt). Kyoto obligations mean that UK landfill emissions need to fall by 20 percent from 1990 levels, and […]

waste diversion targets away from landfill

The UK Government Waste Diversion Targets Set on the Landfilling of Waste (in 2005)

Local authorities across England have been set limits on the amount of biodegradable municipal waste they can dispose of in landfill sites. The aim of these waste diversion targets is to achieve the diversion of waste away from landfill sites. Environment Minister Elliot Morley confirmed (3 February 2005) the final allocation of landfill allowances for […]

Soil washing for contaminated land

Treatment of Contaminated Land by Soil Washing

Soil washing has become an important method for cleaning up contaminated land, and it was first propelled into the main stream as a process for this purpose in the summer of 2004. The reason for this was that the summer of 2004 saw the implementation of EU Landfill Directive requirements which slashed the available number […]

Building on landfill not a good idea

Building on Landfill Sites and Recommendations

We would like to emphasise that, if at all possible, building on landfill sites containing putrescible material, and which therefore are likely to be generating landfill gas should be avoided. Some old landfills will be free from landfill gas, but do take great care to obtain expert advice before you assume that any particular landfill is […]

What old landfills are like inside

Old Closed Landfills and What to Expect if You find One

There are many thousands of closed landfills in the UK. In general all domestic waste landfills filled before the 1950s now exert little or no environmental impact as they contained a low organic content from the start. They did not ever become significantly methanogenic (methane producing), and were: normally shallow (2 to 5 metres deep), […]

what about aerobic landfill

Aerobic Landfill and Why The Subject Will Not Be Forgotten

A key topic raised in many countries, not least Japan, is why most other industrialized nations have gone so strongly for sanitary landfill design, which locks up waste and only slowly allows it to decompose with air (anaerobically) and not aerobic landfills which rot away quickly. The awful longevity of sanitary landfilling, becomes clear when […]

Water content terms for landfills saturation capacity

Definition of Landill Solid Waste Water-Content Terms

There are 3 very important Water-Content Terms Used in the Landfill Industry for the water balance calculations used to predict leachate volumes generated duiring the active life of a landfill site, and these are: Field capacity Field capacity is the amount of liquid that a given mass of material will absorb prior to downward percolation […]
