The Hindu After going through the machine, the organic material can either be converted into manure or utilised for production of energy.

Now, with the city’s garbage woes abating a little, the Bruhat Bangalore Mahanagara Palike (BBMP) has begun scouting for new technologies to manage garbage disposal.

One such technology is the cutter and shredder that will be installed on a pilot basis at Acharya Pathashala in Basavanagudi and Channammanakere Tank Bed in Banashankari.

Demonstration held

A demonstration was recently held at the BBMP head office by the private company that has developed the technology.

H.M. Shivakumar, a representative from the company, said he developed the cutter and shredder to help dispose of all types of organic waste.

He said the benefits were multifold as these machines could help in day-to-day handling and disposal of organic waste in a neat manner, besides reducing the volume by at least 40 per cent.

“This has been successfully tried out at the Siddaganga Institute of Technology, Tumkur. We have converted it into a green campus. This model can be emulated in Bangalore, especially in the many marriage and convention halls across the city,” he said.

Less space required

The space requirement for this is less, which makes it a feasible option for the city.

“To set this up, a semi-permanent shed measuring 20x30 feet to house the machine and curing system will suffice. There is no other requirement,” he added.

Coconut shells and fronds, banana leaves, flower garlands, food and vegetable waste, dry leaves and garden waste can be effectively managed with this system.

“After going through the machine, the organic material can either be converted into manure or utilised for production of energy. By installing this low-cost machine in many places, we can maintain cleanliness in the city,” Mr. Shivakumar said.

Basavanagudi councillor B.S. Sathyanarayana said the machines cost only Rs. 1.5 lakh.

‘Composting possible’

“The organic material can be sent to BBMP parks for composting. I have urged the owners of seven marriage halls in my ward to set it up. Instead of organic waste landing up at the dump yard, we can ensure that it is processed and composted.”
