Mavallipura was one of the three major landfills in the City, the other two being Mandur and Terra Firma on Doddaballapur Road. <br /><br />When the Mavallipura landfill was operational, at least 1,000 tonnes of waste from the City used to go to this dumping yard. The landfill operator, Ramky Environ Engineers, used to process a portion of the garbage and send the remaining filth to the landfill.

The Palike intends to bio-mine the mountain of garbage, but it will cost a fortune.<br /><br />H C Ananthaswamy, BBMP chief engineer (solid waste management), said, “We may require about Rs eight crore to Rs 10 crore to biomine the garbage pile. We have taken various measures to improve the conditions there.”<br /><br />However, the biomining process has not yet begun. As a temporary measure, the Palike covered the trash with earth with the hope that the waste material would decompose in the soil. <br /><br />But the heavy downpour this year washed away the soil and exposed a good portion of the garbage heap.
