Landfills have been one of the oldest means of waste disposal around the world. Historically better known as ‘midden’, this technique was considered as one of the organized forms of waste disposal in many parts of the world. Today, landfills form the basis of the future of waste disposal, due to the ever-increasing population, and an even more exponential growth in the waste generated.
Landfills are the most convenient of all disposal methods available
today; since ‘land’ as a resource is gaining importance quickly due to its growing inability to contain the expanding human race and the demands that accompany it. The skyrocketing monetary value of land in most developing countries is proof enough that land is the new addition to the list of resources to be used economically.
There are several advantages of landfills over open dumping and incineration of garbage. Firstly, the nuisance caused by open dumps like polluted air and land is avoided in landfills. Breeding of disease vectors is also a problem in open dumps that rarely occurs in landfills. Also, the burning of waste in incinerators may cause severe health hazards to the civilians in the vicinity. An example of this would be the incinerator plant, started in New Delhi in 2012. The plant, run by a company named Jindal Saw Limited, gives off eye-watering noxious fumes and toxic exhaust. Apart from avoiding these problems, the cherry on the cake is that landfills end up saving a lot of space, as these spaces can be closed or covered up once they reach their capacity, and beautification programs can be undertaken in these areas such as the development of children’s gardens, parks etc.
There is, however, one important condition for the success of landfills, and that is properly engineered landfill structures. Although these sites do not offer conditions conducive to the breeding of pests and disease vectors, some persistent species like rodents can easily have their way even in these closed structures.
It is known that rodents chew and gnaw on polymeric applications, causing extensive losses in many sectors. Landfills are designed to have a lining made of plastic such as HDPE around each cell. This lining, more famously known as ‘geotextile lining’ cannot remain an exception to the attack of these creatures. Most developing societies today have accepted this form of waste disposal on a large scale. But these structures are often not well protected from the infestations of pests like rodents. The following news covered by Lisa Fernandez gives a brief on the menace of squirrels in a Berkeley landfill. The landfill was covered up, and a park was built over the closed landfill. The squirrels, however, had plans of digging it up again, causing a potential risk of leaching of toxins from the landfill into the nearby San Francisco Bay.
Berkeley Plans to Kill Squirrels Accused of Spreading Toxins From Landfill
Feb 18, 2014 By Jodi Hernandez and Christie Smith – NBC BAY AREA NEWS
And so, the original idea was to simply kill the squirrels. A Berkeley staff report mentioned trapping and killing the rodents, though the method that was to be used to kill the animals wasn’t spelled out.
But the public wouldn’t have it.
Emails, letters, calls and more flooded Berkeley city offices. After months of deliberation by a special squirrel subcommittee, city staff decided the best way to control the squirrels was to crack down on park visitors throwing peanuts and popcorn out on the sidewalk and grass.
The city will now spend $8,000 on new signs and brochures at Cesar Chavez Park informing the public that feeding squirrels are a crime.
The long-term solution to the leachate problem is a protection of the geotextile lining. Killing rodent populations, or putting up fences would not deter these animals for long, and the problem will raise its ugly head like a ground squirrel from its burrow, sooner or later. What we need to do is stop the squirrels and rats from eating away the landfill lining.
This can be done by using C Tech Corporation’s extremely low toxic product, Combirepel™. This is a polymer additive available in the form of masterbatch (plastic granules), lacquer, and also as a liquid solution in an organic or inorganic solvent.
Combirepel™ is an environment-friendly way of keeping the polymers safe from rodents and other such potentially damaging creatures. It does not harm the target or the non-target species, nor does it have any damaging effects on the environment. What it does is simply repel the rodents, and keep the HDPE geotextile lining safe!
This is, without a doubt, the most foolproof, effective, and not to mention, peaceful way of keeping the rodents away, without having to kill them!
