New e-tricycles to make garbage collection easy for conservancy workers

A batch of electric tricycles have been procured by the Greater Chennai Corporation for collection of waste. The tricycles are expected to reduce the physical burden on conservancy workers and enable swifter collection of waste.

Pushing a rickety tricycle and making multiple stops to collect waste from households is a Herculean task for conservancy workers. As the day progresses, the vehicle gets progressively heavier with heaps of garbage but the worker still pushes it, going door to door to collect the waste.  

“Every part of my body aches, literally,” said a conservancy worker, who has been in the job for over 15 years. The long term health effects of their work on these blue-collared workers include persistent shoulder and back pain. 

But there is some good news for them.  This troublesome situation could soon become a thing of the past, thanks to efforts by the Greater Chennai Corporation to make their jobs easy. The civic body has collaborated with Pi Beam Electric, a company incubated at the IIT-Madras research park, to introduce a batch of Electric Trikes (Tricycles sold as Pi Beam E03) for garbage collection. State Bank of India (SBI) has funded the vehicles under their Corporate Social Responsibility (CSR) project. The GCC will own and maintain the vehicles, while Pi Beam will be assisting with scheduled services.

As per the Solid Waste Management rules 2016, it is mandatory to segregate the solid waste at source and to process wet and dry waste separately.  Chennai Corporation has achieved around 42% source segregation so far. To implement segregation at source more effectively, more battery operated vehicles are required. “We recently conducted trial runs with the Pi Beam electric tricycle in Zone 14 and found the vehicles to be suited for the application,” said G Prakash, Commissioner, Greater Chennai Corporation. The trial focussed mostly on vehicle performance with heavy loads and manual effort required to ride the vehicles. 


  • Workers can operate the vehicles for 45km once charged. It takes around three hours to completely charge a vehicle.
  • Every worker has to cover 15 kms each day on average, hence charging frequency will be around one full charge every 3 days.
  • It has a bigger loader capacity that can fit six bins. So it reduces the workload for the workers who take multiple trips to the nearest dumpsites to empty the bins. 
  • Workers do not have to be trained vigorously on the usage of the vehicle, as it is as easy as riding a cycle.

During the trial run conducted at Perungudi (Zone 14), the various difficulties faced by workers while using the traditional tricycle became evident. The inherent weight and presence of crossbar in a manual tricycle makes it unfriendly for any female worker. Most of the conservancy workers toil for more than eight hours a day, going home with a breaking back and heavy shoulders. Pi Beam’s electric trikes addressed both these issues with an easy riding mechanism and a gender-friendly frame design. Workers of both genders were found to be able to ride the vehicles comfortably.

“The tricycle design enables easy climbing and getting down; I look forward to using these tricycles to cover more areas without much hassle,” said a woman conservancy worker at Perungudi. 

The trikes were finally rolled out on November 26th in Zone 5.  Based on findings during the trial run, it is expected that these vehicles will operate at 50% higher capacity, at half the price compared to existing electric vehicles available for the GCC.

Why a waste-to-energy plant is not the answer to Chennai’s garbage problems

GCC has floated a tender for a waste-to-energy plant in Chennai's Kodungaiyur. Here's a lowdown on WTE plants and their environmental impact.

Chennai generates about 6,000 metric tonnes of garbage every day. As the city's population continues to grow, waste generation is expected to increase even more. Not to mention the huge quantities of legacy waste currently accumulating in the Kodungaiyur and Perungudi dump yards. How will the Greater Chennai Corporation (GCC) effectively manage these vast amounts of waste? As this is a common urban issue, the government has proposed a solution already implemented in several other Indian cities. It suggests establishing an integrated waste management project facility, including a waste-to-energy (WTE) plant. It would come up in the North Chennai region,…

Abandoned gods: Discarding religious waste with care

Proper disposal of religious waste is crucial for the environment and helps raise awareness about the waste we generate.

The peepal (Ficus Religiosa) and banyan (Ficus Benghalensis) trees, both members of the Moraceae family, often have raised platforms around them for people to sit and rest under their cool shade. These trees are commonly found near temples and lakes. Believers sometimes place their religious waste under these trees. These include posters, paintings, idols of gods, pictures of ancestors, religious scriptures, clothes that have been used for prayer rituals, disused lamps etc. I spoke to my friend Ashwini who has some knowledge of the scriptures.
