Overview of Drones in Waste Management

In sectors that center around waste management, great investment in labor is required to minimize safety hazards. People are conventionally required to collect samples or manually monitor dumping activities for accurate assessment. Aerial unmanned vehicles, known as drones, have changed the industry entirely. Humans no longer have to play a critical role in painfully monitoring dumping landfills, which tend to come with a baggage of dangerous undertakings. Drones are useful and effective at managing waste sites more than humankind. A drone can operate tirelessly through the most remote places. Finally, drones can take over as key counterparts in aspects of waste management that require laborious and dangerous work.

Reducing Illegal Dumping

Identifying illegal dumping can be difficult because perpetrators often sneak past CCTVs or on-ground investigators by dumping on sites that are not easily accessible or visible. Drones can effortlessly monitor every nook and cranny of the site, uncovering concealed or secluded dumping spots.

To reduce illegal dumping, drones are employed to implement preventative measures. Unlike on-site investigators, drones can identify illegal dumping events while they are happening. These real-time updates enable supervisors to act swiftly increasing the chances of minimizing illegal dumping.

Compared to deployed officers who monitor masses of suspected sites on foot or through land vehicles, drones are faster and effective in identifying the illegal sites because drones remain undisturbed by limiting land factors such as unaccommodating terrain or infrastructural obstructions. Compared to CCTVs, a drone is stealthy and mobile, hence effective at catching perpetrators when they least expect it.

Drones Can Find Illegal Garbage Dumping

Monitoring Beach Litter

Drones monitor beach littering 40 times faster than people. The aerial nature of the unmanned vehicles allows them to swiftly swoop through the air. So, drones are time-efficient in capturing sequential images of the littered shoreline. These sequential images are then sorted and categorized easily through machine learning. Drones then become an improved substitute for human surveyors.

Drones are used to identify types of litter along the shoreline as well. They can capture images of debris as small as a bottle cap through a high-resolution setup. Outsourcing the job of monitoring beach litter to a drone produces a reliable depiction of the littered shoreline.

Landfill Mapping

Landfill managers are required to patrol their sites on foot regularly to tackle potential hazards that tend to fester in landfills. But landfills are massive and difficult to maneuver around. With aerial access from drones, managers no longer have to trudge their feet across the unsteady terrain. On the whole, landfill mapping by drones has proven to be more time-efficient and less labor-intensive.

With photos and videos captured by the drones that seamlessly fly above the grounds, managers can analyze the topography of the landfill. This is then used to survey hotspots of potential threats in the location – from examining slope stability to keeping track of escaping gases that can cause explosions.

Furthermore, a drone’s image mapping is made more accurate than manned surveillance through the use of 3D models constructed from the 2D aerial shot images. These models are useful as drones not only save the physical stamina landfill managers use to assess the landfill site, but they also provide a more accurate and satisfactory inspection of the site.

Thermal Landfill Mapping

In landfill sites, biogas is generated from the mixture of waste, which is potentially explosive. To curb this, drones can be used to detect abnormal temperatures to prevent potential explosions. Drones fly above the landfill sites to scan the area with thermal imaging cameras. These cameras analyze thermal variances within the described perimeters of the landfill. Landfill managers use this data to identify potential risks of an explosion in the site.

With mounted thermal imaging cameras, drones are even more reliable at detecting thermal anomalies than ground-based thermal imaging. They measure many thermal statistics in real-time and send feedback promptly. These drones add value to the thermographic inspection of landfill sites.

Wastewater Treatment

Drones have become extremely helpful in wastewater treatment facilities. They are used to collect and test water samples in inaccessible or hard-to-reach areas. This means that a human’s life does not have to be endangered to do the manual retrieval of the water sample to bring it back for testing. However, a drone can be programmed to meet the flexibility of the employers. For places that are inaccessible or remote, drones are programmed with a specific GPS position and are versatile enough to access the desired depth of the watercourse. At the same time, drones can test samples onboard and send data remotely, which maximizes the safety and efficiency of the whole procedure. Drones revolutionize the process of remote wastewater testing by protecting team members from deploying into harsh environments.

Garbage Collection

Instead of garbage men, a drone-guided robot can collect garbage instead. In this procedure, a drone suspends over the air of the targeted neighborhood to scan its ground mapping. In doing so, the drone scours the ground for garbage bins and possible obstructions that could impede the robot’s way in its tracks. The robot on the ground then receives the feedback from the drone and maneuvers the area with the mapping in mind.

Garbage collecting robot guided by an overhead drone

This procedure simplifies the jobs of garbage men. With the overhead drone scanning the area for collision risks, safety precautions will be taken by the robot on the ground to ensure that infrastructures and civilians are not endangered from harm.

This automation reduces expenses, especially since both the drones and robots are reusable. They make the whole procedure less labor intensive.
