Management
of Hotel Waste
There
are a large number of Restaurants and Hotels in Mumbai. These
hotels contribute substantially to the generation of waste in
a ward. As per our study of a few wards, hotel and restaurant
waste contributes to around 25-30 % of the total waste generated
by the ward.
Types
of Hotel waste:
Hotel waste comprises of two components, Biodegradable (Wet)
waste and Non biodegradable (Dry) waste. The wet waste comprises
of food, vegetable and non veg waste whereas the dry waste comprises
of plastic bottles, papers, plastic wrappers, HDPE, LLDPE bags
etc.
Present
System of disposal of Hotel Waste :
At
present Hotel waste generated by small restaurants is disposed
off directly by the hotels at nearby collection spots. The substantial
quantity of food waste dumped at these collection spots gets
mixed with all the other kinds of dry and wet waste and gives
an ugly look to the collection spots with lot of dirt and stink.
In
case of large four and 5 star hotels, the hotel waste is disposed
off directly by the hotels through MCGM or through private contractors
to the dumping ground.
MCGM
provides a service of directly lifting hotel waste from the
small hotels in some wards such as A , B, H west, M West ward
etc.
MCGM
charges Trade Refuse Charge (TRC) to the hotels for the waste
generated by the hotels. The TRC
is charged in multiples of license fees which is directly based
on the area of the hotel and the grade.
The grade one hotels are generally bars and permit rooms
which do peak business during evening hours. The waste generated
by the restaurants with bars and permit rooms is much less as
compared to that generated by the food restaurants. However
the TRC charged for the bars and restaurants is much higher
than that charged for the ordinary restaurants which generate
much more quantity of waste.
As
per our observations of the hotel waste generated by hotels
in a few wards, around 70 to 75 % of the hotel waste is biodegradable
and gets mixed with all the other type of waste when dumped
at the collection spots. Also the waste which is collected directly
by the MCGM/private contractors gets mixed with all the other
type of non biodegradable waste at the dumping ground.
Suggested
Action Points for MCGM
Management
of waste generated by all the 3,4 and 5 star hotels and restaurants
generating over one tonne of waste by themselves :
These hotels can look at options of in-situ composting, installation
of small biomethanation plants in the premises etc.
At
present, hotel Orchid, Rhodas and Lotus suites are manging their
waste quite well and can set an example for other hotels.. MCGM
should enforce in-situ management of waste generated by these
hotels.
Direct
collection of waste generated by hotels my MCGM and its localized
disposal
: MCGM should look at direct collection of hotel waste
and set up zone wise processing facilities (either composting
or biomethanation. MEDC is evaluating various technologies for
biomethanation and developing a business model. The report will
be ready in a couple of months).
This will substantially reduce the transport cost as
well as the load on the dumping grounds. The public collection
spots will also get less amount of garbage.
Some
methods for management of Hotel Restaurant and Club food waste
could be as follows :
Bio
Sanitizer by Excel Industries :
Excel Industries Ltd. supplies machines of capacity 500kg, per
day, 1 tonne per day and 3 tonnes per day machines along with
biosanitizer. This machines can crush the food waste to 1/3rd
of the original volume and odourless compost produced can be
used as manure after curing. (Details can be available with
Excel Industries).
Biomethanation
:
Biomethanation Plants of capacities 100 -500 kg per day can
be installed in the premises of hotels if adequate space is
available. Gas generated can be used for cooking.
Composting/
Vermicomposting – Options of composting/vermicomposting
could be explored.
