The BBMP plan to buy 122 tree and plastic shredder at Rs 20.60 CR leaves a lot to be desired, say Solid Waste Management Expert
Bruhat Bengaluru Mahanagara Puee (BBMP) has decided to invest RS 20.60 Crore to buy, operate and maintain 122 small and large destroyers to reduce the volume of branches of trees, leaves and plastic waste among others.
However, the Civic body has no evidence to justify its investment as a similar destruction machine purchased in the past lying silent or dead.
Even solid waste management experts do not approve of this large-scale expenditure.
In accordance with official documents, the BBMP estimates RS 14.99 Crore as a capital cost for the procurement of this machine and regulates infrastructure while operating costs and maintenance for a year is estimated at RS 5.54 Crore.
The BBMP has flooded the tender for the lowest project and bidder that clears technical evaluation and has maintained a minimum of ten similar equipment for at least three years to get a three-year contract.
The funds were intended in the Shubra Bengaluru program announced in 2019.
There will be around 122 machines with different destroyers capacity.
Of these, 90 machines can each damage 1 ton per day, eight shredders can damage two tons per day, 16 shredder can each be destroyed five TPD and eight shredder can damage 10 TPD.
They will be used for purposes such as tearing up or cutting trees

Officials said these machines were being built in line with the rules of solid waste management, 2016.
BBMP also promised to reduce solid waste value by tearing up or reducing transportation costs.
Officials say that grated plastic will be used for road construction and grated organic waste will be used as direct dirt.
Plastic shredders will help only if BBMP appears with a system where grated plastic is used for road construction or at the factory to produce cement or coal.
There is no point in just knocking down plastic waste – Nalini Shekar from Hasiru Dala
Sandhya Narayan, a solid waste management expert, is not happy with the purchase plan.
“The BBMP has bought at least 10 shredders like that three years ago.
They are dead or not used because no one takes responsibility for maintaining the machines,” he said.
“The destruction machine does help reduce the transportation costs of dry leaves from wards,” he added.
While BBMP has floated tenders to buy shredders, officials have not placed a system or location identified where grated dry leaves can be converted into manure or soil.
Nalini Shekar Hasiru Dala said about 40 percent of dried waste produced in the city cannot be recycled, which landed in a cement plant or landfill.
“Plastic shredders will only help if BBMP appears with a system where grated plastic is used for road construction or in a factory for cement or coal production.
There is no point in tearing plastic waste,” he said.
Because BBMP is currently in the stage of transferring all jobs and programs related to solid waste management to new companies, officials do not want to comment on the project but agree that tenders have floated to buy machines.
