Solid Waste Management of Dibrugarh Municipality Board:

Present Status, Challenges and Its Future Prospects.

Presented by: Annesha Mech

Introduction:

Solid waste are unwanted materials disposed off by man which can neither flow

into the streams nor escape immediately into the atmosphere causing pollution of

air, water and soil.

Solid Waste Management (SWM) has been a neglected area of urban development

and often accounts for severe health and environmental problems. Proper waste

management includes various aspects: source reduction, onsite storage, collection

and transfer, processing and disposal.

Dibrugarh Municipality Board (DMB) established in 1873,is responsible for SWM

within the municipality limits of Dibrugarh town, spreading over an area of

15.40sqkm divided into 22 wards.

Objectives:

1) To study the existing status of solid waste

management of Dibrugarh Municipality Board

2) To identify problems faced by DMB in waste

management

3) To study initiatives that are planned to be

undertaken by DMB.

4) To suggest some ways for improving SWM in

DMB

Methodology:

• Visit to Dibrugarh Municipality Board,

• Dumping site in MaijanPrimary data

• Collected from newspapers, journals and website of dibrugarh municipality.

Secondary data

1. Existing status of Solid waste management of Dibrugrh Municipality Board:

• Solid waste generation within the municipality area is

about 60 to 65 metric tones per day.

• No formal door to door garbage collection.

• there are about 15 big dustbins and 40 small dustbins

• nine tractors, 2 robot waste collector cars, 1 dumper

and 3 excavators are involved in collection, disposal

and leveling of waste.

• Waste are collected from the roadside bins and are

disposed off at dumping ground in Maijan with no

further treatment.

• Assam Medical College has the only Bio-medical

waste treatment facility with an incinerator capacity of

150kg.

Discussion:

2. Problems faced by the Dibrugarh Municipality Board in waste management:

Generation of solid waste are increasing with rise in population and increase

in economic activities.

Due to financial constraints labourers employed are inadequate and unskilled,

lesser vehicles are available for waste collection and disposal.

No suitable technology available for treating garbages.

Availability of only 1 dumping ground where untreated waste are being

disposed since 1981, resulting in piling of waste and about 80% of the

dumping ground has been filled up which is a matter of great concern where

the future waste will be disposed off.

People tend to throw the waste on the adjoining roads and outside dustbins

increasing the work of collection staff of DMB.

Waste being thrown outside the dustbins

Untreated waste in the dumping ground of Maijan leading to degradation of environment.

3. Initiatives that are planned to be undertaken by Dibrugarh Municipality Board for waste management:

Dibrugarh will have a waste management

plant worth Rs.16 crore near Khanikar farm,

about 6 km away from Dibrugarh town which

will be financed by Asian Development Bank.

The ADB had further agreed to give a loan of

Rs.150 crore for clearing the main drain from

Paltan Bazar to the Sessa river.

4. Ways for improving solid waste management by Dibrugarh Municipality Board:

• Improving waste segregation and storage at source.

• Improving collection of waste through door to door collection of

segregated waste.

• Adoption of some scientific and eco-friendly methods of disposal and

treatment of solid waste which are as follows:

Recycling of organic waste:

(a)Vermicomposting

(b) Biomethanation (anaerobic digestion)

(c) Aerobic composting

Treatment of inorganic waste depends on its physical and chemical

characteristics and on its reuse potential. The inorganic waste should be

segregated into recyclable and non-recyclable. Waste recycling in

Dibrugarh Municipality area has many untapped potentials.

Thermal treatment techniques:

(i) Incineration

incinerators

(ii) Gasification technology

(iii)Refuse derived fuel technology

Sanitary landfills will minimise migration of leachate through

soil strata, supress the foul odour and improve the aesthetic

quality.DMB should discontinue open dumping and adapt

sanitary landfill practices.

Conclusion:

•Adopt sustainable solid waste management practices by adapting various

eco-friendly methods of waste management.

• Cooperation among public and municipality.

• Outsourcing certain services and resorting to public private partnership/

Non-governmental Organisation participation in providing certain SWM

services inorder to improve efficiency and services of Dibrugarh

Municipality Board.
