All of us are producing waste everyday but have you ever thought about what happens to the waste that is created after the garbage or trash pickup? It is sure that “landfills” come to our minds when we think about this. As we know, landfills are the areas that are used for waste disposal by preventing our environment from pollution and health risks. It is known as one of the most used disposal methods of municipal solid waste management.
It is important to remember that these landfills are not open dumps since landfills have an engineered mechanism to decrease the environmental effect. Landfills have to comply with regulations regarding their location, design and operation. Also, these landfill processes are monitored very closely in order to control any sign of groundwater contamination and landfill gas.
Especially engineered landfills which need highly skilled operators and experts design can be thought as good for environmental health. It would result in an effective disposal if it is managed well. However, if the landfill management is not done properly again, it leads to environmental pollution.
Types of Landfills
Landfills have three types, firstly there are municipal solid waste landfills that are designed to hold household waste and some other non-hazardous wastes. These landfills can also use bioreactors. Second one is, industrial waste landfills which are designed to receive industrial and commercial waste. Third one is hazardous waste landfills that are used for the disposal of hazardous waste in a way that keeps our health and environment safe.
Problems of Landfills
For sure landfills also consist of some problems. One of the most common problems that you can hear is probably the gas release in landfills which can lead to environmental problems. Moreover, liquid releases can be counted as another problem of these areas that can contaminate underground waters. These liquids are needed to be captured by workers. All of us are asking the same question here, can we prevent all of these problems?
The answer is yes actually. Again here, technological developments and advanced engineering skills can save us. The common point of both of these problems are the release of liquids or gases, so this point needs to be prevented. The gas and liquids are needed to be captured and collected. Technology has led us to collect all these releases firstly but in addition to this we can produce electricity from the gases!
Principles of Modern Landfills
In modern landfills we can see that the trash is buried in levels which are compacted and covered and also, we can see a protected bottom in order to prevent contamination of groundwater. Moreover ideally 0.5 meters of soil should cover the waste in order to prevent animals from digging the waste.
In addition to this, in modern and engineered landfills we can see a lot of technological advancements regarding the monitoring and tracking of landfills. In these ones, one liner system can be observed at the bottom and in the sides, a leachate removal system that is for gas extraction and groundwater monitoring. Furthermore, in order to decide on the area that the landfill will be operated, a risk management system for assessment of the risk can be seen.
Another technology that is seen is bioreactors. This technology is used to turn complex organic molecules such as papers, food etc. into less toxic smaller compounds. By the activity of bioreactors, we can see the production of biogases. These gases can be managed also by collecting properly. We can observe gas collection systems in some landfill areas in order to generate electrical energy.
In all of the processes that are mentioned; collecting, reporting and monitoring the information is crucial. Transporting these waste to landfills and after the waste disposal process is highly complex and everyday we are generating more and more waste which makes it more difficult to keep track of. In order to keep up with all this information and manage it well we need the help of technology.
Management of the increasing waste in urban life is inevitable and local authorities are having a lot of problems in managing these wastes especially in landfills. As Evreka, we are caring about our environment and we are producing advanced digitized solutions to reach a healthier environment and a better life for all. Keeping track of information and monitoring these landfills might give hard times in waste management but we are here for you. Our solutions that are highly digitized will help you to monitor these processes easily in one platform and will help you to provide a more efficient and effective waste management process.
