DHAKA DEBRIS MANAGEMENT PLAN

AWAL UZ ZAMAN

UNDP refers to "Debris” as the mixture of building waste and rubble arising from building demolition.

OBJECTIVE

To provide operational guidance and specific action for the government of Bangladesh to conduct a large scale debris operation in the event of a catastrophic earthquake in Dhaka city

ROLE OF BD ARMY

# Provide Trained search and rescue teams, rotary wing airlift, debris clearance and engineering cap

# Cantonment Area within the Dhaka metropolitan city will be dealt under existing rules and regulation of Bangladesh.

# Armed Forces Division has also divided the city into 8 zones

# AFD will be working in the Early response phase

POST DISASTER DEBRIS MANAGEMENT• It is imperative for a country like Bangladesh to prepare a post disaster

strategy • Debris management is a key part of post disaster strategy.

Typical debris stream after Earthquake  

Construction and demolition : Building materialsHazardous waste : Fuels, oil, batteriesMunicipal solid waste : HH garbage, personal belongingsPutrescible : Food waste, organic matterWhite goods and vehicles : Refrigerators, ACSpecial waste : Archeological importanceGeological : Soil, mud and sand

Plan

• 1. City corporation may issue notice to risky buildings and tell them to fix it, otherwise it may fix it and people may pay additional tax

• 2. if unnoticed by owned and seriously risky, it can be demolished at the earliest time

Stages• Normal Time• Alert and Warning Stage• Disaster Stage• Rehabilitation Stage

DEBRIS MANAGEMENT CYCLE

Importance of Debris Management Plan:

Expedites the removal of debris thus helping in speedy recovery of the affected communities.

Protect human health and environment by proper removal and organization of debris based on its types.

Identify the cost effective debris management options that can save money and spaces for debris disposal.

Debris Management Cycle

CHALLENGES IN POST EARTHQUAKE DEBRIS MANAGEMENT

• Bangladesh Government senior policy makers and staff may be unavailable initially for response.

• Major approach will initially be blocked and access to the city for immediate relief will severely disrupted

• Open space within the city will be immediately overwhelmed by displaced persons

• Debris Clearance, Transport and Disposal Response

CHALLENGES (CONT.)

DEBRIS CLEARANCE AND DISPOSAL

• The lack of preparedness and technical capability in part of the government to carry out rescue missions and debris management

• Financial Constraints

• Environmental, Health and Safety Consideration

• Lack of Rules and Regulation Pertaining To Disaster Waste Management

CHALLENGES (CONT.)

ENVIRONMENTAL, HEALTH AND SAFETY CONSIDERATION

• The volume of paint and lead from damaged houses and building could reach million liters

• Other hazardous wastes include battery and mercury • Locals directly exposed• Lack of proper protective measures and first aid for demolition workers and supervisors.• Skin problems, Damages to Kidney, Lugs and Nervous System

OPPORTUNITIESRECYCLE, REDUCE AND REUSE (3R)

POTENTIAL OF DEBRIS

Economic and Environmental Benefits Reduction in the cost of debris removal and disposal Reduction in space used for landfill and transportation costs Revenue from recycled aggregates Job creation especially in developing countries Vegetative waste can be reduced by composting which can then be used for

diverse purposes

OPPORTUNITIESCONSTRUCTION AND DEMOLITION DEBRIS (C&D)

C&D debris represents a large portion of disaster debris but provide an excellent opportunity for recycling, reuse and reduction.

• Masonry materials, such as brick and blocks, and concrete could be used in the landscaping industry.

• Timber and other wood products can be used in variety of ways • Asphalt shingles could be recycled into new asphalt pavement mixes or used at a

cement kiln. Drywall can be recycled into new dry wall, cement and agricultural uses.

• Metal is already typically recycled, therefore metal recycling after a disaster is very promising.

RISK FACTORS

• Disaster events can generate large quantities of debris and management of such debris can present a major challenge

• Lack of preparedness and technical capability in part of the government to carry out rescue missions will be lengthy

• Also, to put the plans into action government needs to overcome financial constraints and address issues related to efficiency, transparency and governance

• Post-earthquake debris, especially Construction & Demolition debris, have enormous 3R potential

• These 3R strategies can bring numerous economic, social and environmental benefits

Refuse Reuse Recycle

3 Basic Recommendation

RECOMM

• 50% of the estimated budget should be managed from local level• A combined effort of technicians, specialist and locals will ensure speedy and

justifiable recovery. • Increase the community realization that all debris are not waste, thus helping

in reuse and recycling of debris. • Debris can be used for land reclamation in shallow areas

RECOMM

• Local disaster management and reconstruction should be formed • Maximum involvement of local communities • For monitoring the project, a monitoring team consisting of local political

representative should be formed• The site for disposal of debris should be guaranteed

RECOMM

• Hazardous waste pose immediate threat to human health, safety and environment. Hence, it is critical to guarantee its proper management.

• Necessary safety measures needs to be put in place for demolition workers, handlers and supervisors. Only skilled workers should be designated for high risk works.

• Finally, it recommended that health, environment and safety expert be appointed, either by the government or independently, who can advise on potential hazards.

CONCLUSION• Furthermore, government should create necessary working environment for

professionals including engineers, environmentalist, geologist and contractors working in this field.

• Finally, local political parties and non-governmental organizations (NGOs) should also contribute in these initiative through active coordination and monitoring
