3.3.9 Solid Waste Collection and Disposal
Contractors working under the supervision of the estate services staff are responsible
for collection, segregation, disposal and recycling of solid wastes generated in MAF
and RAH areas. Four types of wastes, viz., domestic wastes, office wastes, clinical
waste and STP sludge are generated. The wet domestic wastes are sent directly to the
municipal landfill site for disposal. The dry domestic waste along with the office
waste is sent to PDO’s waste processing plant for further segregation, recycling and
disposal. The STP sludge is dried in sludge drying beds and disposed on land as a soil
conditioner.
Clinical wastes generated in the MAF medical clinic as well as PDO clinics in the
interior assets are thermally destroyed in an incinerator located in the waste
management centre in PDO. No human anatomical wastes are generated since
surgical procedures are not performed in the clinics. Clinical waste is received at the
waste processing plant in puncture proof cardboard boxes. These boxes are directly
loaded into the incinerator. The incinerator is operated approximately once a month to
destroy the stockpile of clinical waste generated from PDO’s coastal and interior
clinics.
The detailed description of waste management including the design and operation of
the waste management centre and the incinerator is presented in Chapter 4.
3.3.10 Roads and Parks Maintenance
Within the MAF and RAH areas, there are 26 km long roads in the residential areas,
11 km long roads in the industrial area and 11,400 m 2 of car park area. In addition,
there are lawns and gardens covering a total area of about 10,000 m 2 within the MAF
and RAH areas. The estate services staff are responsible for the maintenance of roads,
car parks and landscaping in these areas through contractors. The routine maintenance
activities consist of sweeping the roads and minor asphalt repairs. The resurfacing of
the roads and painting the car parks is done where required. All the necessary
equipment and materials are brought in by the relevant contractor and any wastes
generated are managed and disposed of by the contractor according to PDO’s
specifications.
For the maintenance of lawns and gardens, PDO uses only treated sewage, which
fully meets the MRME&WR discharge standards for land irrigation (Standard A-2).
To ensure good growth, small quantities of fertilisers are used. The use of pesticides is
rare. Further, the lawns are regularly mowed and the trees and bushes are trimmed.
