PROJECT: EMI and Magnetic surveys at closed waste disposal sites LOCATION: Holloman Air Force Base near Alamogordo, New Mexico PROJECT DESCRIPTION: Designed and performed total-field magnetometer surveys in tandem with EM-31 terrain conductivity (EMI) surveys of approximately 53 acres of closed landfills at an Air Force base in New Mexico. Survey was designed to detect buried metallic debris and soil conductivity. The magnetic method successfully identified numerous burial locations and the EM-31 method successfully delineated boundaries of old landfilling sites. Performed detailed data reduction and provided Client with line-contour and color-contour maps with Latitude-Longitude coordinates.
Summary
Biorem`s biogas desulphurization product is providing very high removal efficiencies at a landfill site in Quebec. Despite the highly variable concentrations and low winter temperatures, the system has achieved an average removal efficiency of 97%, and has maintained outlet nydrogen sulphide concentration below target consistently. As a result, the customer has realized a significant cost reduction over the previously used chemical scrubbing process, and site environment has improved.

The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the derogation that allows Air Pollution Control residues to be disposed of to landfill at three times the standard waste acceptance criteria (3xWAC) threshold for hazardous landfill. Chief technical officer, David Deegan, explains why below:

For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires can float like balloons to the surface, sometimes rupturing the protective liners that keep contaminants from polluting...
One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints.
In fact, compared to other industrial applications such as wastewater treatment and asphalt production, landfills face more challenges in fighting odors. Moisture, humidity, agitation, and summer temperature can...
AutoPumps Keep the Power On for Thousands of Florida Homes
Waste Management`s Springhill Regional Landfill near Campbellton, Florida generates "green" energy by extracting and burning the methane in landfill gas. Its $7 million landfill gas energy (LFGE) plant, with six large Caterpillar engines running 24 hours a day, 7 days a week, is capable of producing 4.8 million watts of power. Most of the energy goes to the Alabama Electric Cooperative for distribution to customers, enough to supply the electrical energy...
