ndia presently generates 62 Million Tonnes / year (5.6 plastic
waste, 0.17 biomedical waste, 7.9 hazardous waste and 0.15
E-waste). Per capita waste generation ranges from200 grams to
600gramsper day.Out of collected43million tonnesperAnnum
(75-80%)ofmunicipalwaste,11.9millionistreatedand31million
is dumped inmunicipal landfill sites (22-28%). Out of hazardous
waste3.41mnMT (46%) goes forTSDFsites, 0.69mnMT (9%) for
Incineration and 3.35mnMT (45%) for recycling. By 2030, waste
generation will increase up to 165 million tonnes per annum.
Present regulations allow disposal of waste through landfill is
conversion fromone phase to another and it adds to loss of land
and resources. Waste hierarchy suggests to focus on prevention
first and disposal at last. Between these two ends one has to
explore various options for reduce, reuse, reprocess, recycle and
recovery of waste. These 5R principles of waste management
have become essential for Sustainable Development.
Port & logistics do generate Solid Waste along with Industrial
waste, Bio-medical Waste and E-waste. APSEZ has adopted a
vision of Zero waste to landfill by 2020.
Solid Waste includes paper, plastic, metal, glass, rubber; scrap
etc. is segregated at source, sent for recycling. Non-recyclable
waste (Refuse Derive Fuel) is sent for co-processing in Cement
kiln as a fuel. Other inert material can be converted to paver
block and used for infrastructure activities. All biodegradable
waste is converted to manure and same is used in-house for
horticulture purpose. E-waste including other materials such as
metals, plastic etc. APSEZ is towards the path of Zero Waste to
Landfill.
These practices results in saving of land, resources, money,
emission, pollution and helps generate revenue. Time has come
to focus on value added initiatives tomakebusiness Sustainable.
