With responsibility for a large area of northern Scotland and the western isles, Highland Council invests considerable sums of money on monitoring the environmental impact of 14 landfill sites throughout the region. This involves regularly testing surface water, groundwater and leachate samples for various components as well as monitoring the production of landfill gases. Testing schedules therefore generate considerable quantities of data.
To handle this data technicians employed numerous spreadsheets but they often experienced difficulty entering and extracting the information efficiently. After installing Monitor-LT the council found that data handling and assessment was greatly simplified. Both are now more perform. Council staff have also benefited from being able to view historic data for metal contaminants that are nearly exceeding therefore been spotted early. Figures exceeding consent levels are usually flagged up at the data entry stage.
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...
Green Bay adds Gas-to-Energy Facility to 30-year-old Landfil
Brown County East Landfill in Green Bay, Wisconsin recently completed a feasibility study that determined it would be economically sound to convert methane gas into electrical energy by electric generators to the site. Two new Cat 3516A+ engines are projected to come on line in December of this year, housed in a new 30 x 100 foot building that will also contain the other gas processing equipment. "We will be able to process 620 cfm through the system,...
