Bin it Right

Cities adopt smart solutions to streamline their waste management processes

One of the prerequisites for building a smart city is effective monitoring and management of solid waste. Unfortunately, most Indian cities fail to treat their waste effectively as the existing solid waste management (SWM) infrastructure is inefficient and inadequate. The lack of technology penetration in SWM is the key reason for the dismal scenario. Urban local bodies (ULBs) do not have internet of things-based devices, and information and communication technology (ICT)-based solutions. One of the key objectives of the Smart Cities Mission is to promote the adoption of smart technologies to deal with the issue of waste management. Intelligent technology solutions such as smart bins with sensors, radio frequency identification (RFID) tags on transportation vehicles and GPS are gaining ground under the mission. Cities such as Surat, Indore and Coimbatore have already introduced smart solutions to streamline waste management processes. Other cities too need to deploy similar technologies and create awareness among end users to attain zero discharge status.

Solutions in store

In most cities, the process of waste management is inefficient. It begins with the segregation of waste at source and is followed by collection. ULBs do not have the required manpower and expertise to monitor the process on a real-time basis. Thus, it is essential to adopt solutions such as smart bins with sensors, smart garbage haulers with GPS tracking facility and on-board weighing systems, and obtain access to smart mobile applications for monitoring of waste activities.

Surat has introduced several initiatives to manage the waste generated in the city. As part of the mission, 43 underground garbage bins (each with a waste carrying capacity of 1.5 tonnes) have been deployed across the city. These bins are equipped with ultrasonic sensors for measuring the level of garbage and sending alerts to the control room as soon as the container is 70 per cent full. The alerts are sent through an ICT-enabled GPS system deployed in bins as well as on trucks. For door-to-door waste collection, the ULB has deployed about 425 smart garbage haulers on 900 routes across the city. Each of the vehicles is equipped with an RFID tag along with GPS for tracking their movement on a real-time basis. This has helped the Surat Municipal Corporation improve the productivity of vehicles, reduce non-compliance and optimise fleet utilisation. Other IT components such as hardware (servers), software and network devices have been installed at the control room to monitor activities through the dashboard and prepare a detailed analysis report for informed decision-making.

Another technology solution, a mobile-based smart waste management application helps overcome waste management challenges. Technology providers develop mobile applications embedded with various modules such as bin management, vehicle management and weight management, among others, to monitor each activity individually. Indore has introduced a similar mobile app called Safai Mitra for its citizens. Data on primary and secondary waste collection is sourced and compiled on this app. In August 2018, Coimbatore too launched a mobile application for streamlining its garbage collection process. The mobile application receives information through RFID tags and sensors, which are deployed on garbage collection vehicles. Waste collection workers scan the quick response codes placed on different bins and all the data is sent to the application.

Key benefits

Through these smart solutions, ULBs can improve their performance by expediting the waste collection process, ensuring real-time monitoring of vehicles and reducing the time for rerouting vehicles to waste bins by tracking vehicles that are closest to the point of collection. Further, the installation of mobile applications for SWM empowers the end beneficiaries by enabling quick complaint and grievance redressal. Also, the reliance on intelligent technologies reduces human intervention, thereby eliminating the chance of error.

The way forward

The integration of smart technologies with waste management practices is the way forward for cities to achieve zero discharge status. Citizens need to adopt waste segregation at source and use mobile applications to expedite the waste management process. Moreover, smart cities must create greater awareness about new methods and technologies in other cities to enable greater uptake.
