Advantages of Smart Waste Management | disadvantages of Smart Waste Management
This page covers advantages and disadvantages of Smart Waste Management system. It mentions Smart Waste Management advantages or benefits and Smart Waste Management disadvantages or drawbacks.
What is Smart Waste Management System?
As we know smart city concept has been evolved in order to provide decent quality of life to human beings. Smart waste management is one of the many essential requirements of the smart city. The other components include smart security, smart energy management, smart healthcare infrastructure, smart mobility, home automation and building technologies such as zigbee, Lora etc.
Everyday massive volume of solid waste is produced by humans which amounts to hundreds of kilotonnes. The disposal of which is a major concern for them. Smart waste management uses devices such as smart dustbins to robotic road cleaners coupled with smart transportation vehicles to clean up the collected and compressed wastes. Smart mobility vehicles are connected with smart dustbins using wifi/cellular connectivity over internet. The system uses GPS and software applications to guide trucks to choose the shortest path based on fill level of wastes.
Smart dustbins can also be used for other operations such as ticket bookings, bill payments, to display advertisements and so on. Underground garbage bins are installed in order to prevent open and untreated waste accumulation across the cities at various places.

Smart bins are installed with various types of sensors with specific functions. For example, fill level sensor notify waste collection team when the bins are filled upto 70% capacity. As a result of notification, team can clear the bins in due time. In smart cities, sewage drain coveres are equipped with sensors which can detect when sewage fluid overflows which alerts the concerned teams.

which has following features.
• It performs intelligent compaction of waste by monitoring fill level in real-time using sensors. It relays the information to clean city networks which consists of team of people dedicated to collect the waste from these smart bins.
• It houses solar panel on top which converts solar energy into electrical energy to be stored in the battery for situations when there is no sublight.
• It is protected by polycarbonate shield which is resistant to external forces.
• The smart bins can hold 8 times more waste compare to normal waste bins.
• It houses intelligent safety sensor which stops compaction cycle when it detects hand of human being.
• It houses fire detection sensor which triggers immediate notification to the emergency team in case of fire.
• Smart bins are equipped with bi-directional communication link which relays informations in real time which include fill level capacity, collection efficiency etc.
• It is available in different sizes. The higher size bins are compatible with wheelie bins available around the world.
• It contains LED backlit option which is used to display advertisement to generate additional revenue. It can also be visible even at night time.
Benefits or advantages of Smart Waste Management
Following are the benefits or advantages of Smart Waste Management:
➨It saves time and money by using smart waste collection bins and systems equipped with fill level sensors. As smart transport vehicles go only to the filled containers or bins. It reduces infrastructure, operating and maintenance costs by upto 30%.
➨It decreases traffic flow and consecutively noise due to less air pollution as result of less waste collection vehicles on the roads. This has become possible due to two way communication between smart dustbins and service operators.
➨It keeps our surroundings clean and green and free from bad odour of wastes, emphasizes on healthy environment and keep cities more beautiful.
➨It further reduces manpower requirements to handle the garbage collection process.
➨Applying smart waste management process to the city optimizes management, resources and costs which makes it a "smart city".
➨It helps administration to generate extra revenue by advertisements on smart devices.
Drawbacks or disadvantages of Smart Waste Management
Following are the drawbacks or disadvantages of Smart Waste Management:
➨System requires more number of waste bins for separate waste collection as per population in the city. This results into high initial cost due to expensive smart dustbins compare to other methods.
➨Sensor nodes used in the dustbins have limited memory size.
➨Wireless technologies used in the system such as zigbee and wifi have shorter range and lower data speed. In RFID based systems, RFID tags are affected by surrounding metal objects (if any).
➨It reduces man power requirements which results into increase in unemployments for unskilled people.
➨The trainining has to be provided to the people involved in the smart waste management system.
