It took more than a decade and crores of rupees (approximately

Rs 350 crore a year) for the Bruhat Bangalore Mahanagara Palike (BBMP) to create the highly toxic garbage hillocks at Mavallipura and Mandur. Now the civic agency will spend another decade and crores of rupees to undo the damage. As part of its 'social responsibility,' the Palike will undertake the Herculean task of detoxifying Mandur and Mavallipura landfills which bore the brunt of City's unprecedented growth in the last two decades. It will disintegrate the garbage mounds oozing leachate and emanating unbearable stench, by biomining and deodorising them.
