## ANSWER

## MINISTER  OF  STATE  IN  THE  MINISTRY  OF  ENVIRONMENT,  FOREST  AND CLIMATE CHANGE (SHRI BABUL SUPRIYO)

(a) to (d) The Ministry had notified the Solid Waste Management Rules in 2016. The Rules prescribe that no waste generator shall throw, burn or bury the solid waste generated by him, on streets, open public spaces outside his premises or in the drain or water bodies.The Rules prescribe the waste generators to segregate the waste at source and hand over the segregated waste to authorized waste pickers or waste collectors.

As far as scientific technique is  concerned, the Rules prescribes to setup material recovery facilities  with  sufficient  space  for  sorting  of  recyclable  materials;  collect  waste  from vegetable, fruit,flower, meat, poultry and fish market and promote setting up of decentralized compost plant or bio-methanation plant at suitable locations; facilitate construction, operation and maintenance of solid waste processing facilities and associated infrastructure including the following:

- i. bio-methanation, microbial composting, vermi-composting, anaerobic digestion or any other appropriate processing for bio-stabilization of biodegradable wastes;
- ii. waste  to  energy  processes  including  refused  derived  fuel  for  combustible  fraction  of waste or supply as feedstock to solid waste based power plants or cement kilns;

The Rules stipulate specific criteria to encourage the use of solid waste in the waste to energy plants.  It  has  been  mentioned  that  (i)  non  recyclable  waste  having  calorific  value  of  1500 K/cal/kg or more shall not be disposed of on landfills and shall only be utilised for generating energy, (ii) High calorific wastes shall be used for co-processing in cement or thermal power plants.

The plastic waste invariably forms the part of solid waste. Therefore, for the plastic waste, the key technologies prescribed are (i) utilization of plastic waste in road construction, (ii) Coprocessing of plastic waste in Cement Kilns, (iii) Conversion of plastic waste into liquid RDF (Oil) and (iv) Disposal of plastic waste through Plasma Pyrolysis Technology (PPT).

The  Rules  provides  specification  for  sanitary  landfills  including  criteria  for  site  selection, development  of  facilities,  pollution  prevention,  water  and  air  quality  monitoring  etc.The Rules also provide criteria for closure and rehabilitation of old dumps. The solid waste dumps which have reached their full  capacity have to be closed and rehabilitated by reducing the waste by bio mining and waste processing followed by placement of residues in new landfills or capping. The Central Pollution Control Board has also issued guidelines for maintaining buffer zones restricting  any residential, commercial or any other construction activity from the outer boundary of the waste processing and disposal facilities.
