• HR square arranges for cleaning of roads, medians, streets, footpaths, cycle tracks, lanes, bye lanes, surface drains, side beams by mechanized and manual means, at daily at regular intervals and used containerized device for collection and transportation of such waste.
• HR square approximately covers a road length of the Campus is 55.00 KM (in equivalent single lane of 3.0m) approximately.
• The mechanical sweeping is conducted on the Carriageways where it is conducive for the same. The remaining portion of the road stretch (i.e. where mechanical sweeper is not able to work) on both sides (upto2m of shoulder/kerb/footpath/median/central verge) is cleaned manually and was made litter free as a complementary cleaning.
• HR square cleans all street furniture, statues and road side signages falling within the jurisdiction of assigned road stretch as a complementary cleaning.
• The street sweepings and silt collected from the surface drains never accumulates on roadsides and was transported directly to waste disposal facility as a complementary cleaning.
• HR square performs trimming, pruning of excessive, unsafe growth / loosening of tree branches and vegetation along roads, corners and turns in such a way that the areas remain aesthetic, green yet safe for vehicular and pedestrian movement.
• HR square maintains the grass in the side berms and that in the designated green covers trimmed in the range of 25mm to 75mm.

• Waste collected was directly transported to the designated waste temporary storage area for handling and onward disposal.
• Vehicles used for transportation of wastes were covered and a facility was maintained to prevent waste spillage and leachate dropping from the vehicles on the ground en-route to the processing or disposal facility.
• Waste was never made visible to public, nor exposed to open environment preventing their scattering.
• Separate transportation of domestic hazardous waste was arranged as directed by the State Pollution Control
• Construction and demolition waste were transported in covered vehicles separately.
• Transportation vehicles was covered and so designed that multiple handling of wastes, prior to final disposal is avoided.

• HR square sets up waste handling and material recovery facility where non-bio-degradable or recyclable solid waste was collected, temporarily stored, segregated, and processed.
• HR square segregates and handles with suitable technology for processing & to make use of all components of wastes to minimize burden on landfill.

Following criteria was adopted, namely:

• Biodegradable wastes was processed by bio-methanation, composting, vermi-composting, anaerobic digestion or any other appropriate biological processing for stabilization of wastes.
• HR square ensures that composting or any other end product is in complying with the applicable standards and also ensured that no damage was caused to the environment during this process.
• Dairy waste was used for bio-methanation or vermi-composting or aerobic composting.
• Arrangement was made to provide segregated recyclable material to the recycling industry by the HR square for the purpose.
• Non-recyclable plastics and other high calorific content waste was utilized for co-processing in cement kilns or for polymer or fuel production or manufacturing of products such as door panels etc,.
• Construction and demolition and other inert wastes is utilized for making bricks, pavement blocks, construction materials such as aggregates, filling material in construction industry.
  • Residual combustible wastes is disposed for utilization as a feedstock for preparing refuse derived fuel (RDF)

• All waste collected, handled and primarily processed within the designated waste handling site was disposed by HR square at its own commercial discretion with a frequency so as to keep at least 30% of waste storage area.
• The waste collected from the IIT Kharagpur campus is treated / disposed as per Government solid waste management rules 2016.
