MAIN ISSUES 
- Absence of segregation of waste at 
source 
- Lack of technical expertise and 
appropriate institutional 
arrangement 
- Unwillingness of ULBs to introduce 
proper collection ,segregation, 
transportation & treatment/disposal 
systems 
- Indifferent attitude of citizens 
towards waste management due to 
lack of awareness 
- Lack of sufficient funds with ULBs 
Punai Chak,Patna - 2014 
Boring Road, Patna - 2014
PRESENT STATUS OF WASTE MANAGEMENT 
- Storage of waste at source is 
lacking 
- Domestic waste/Trade waste is 
thrown on streets 
- Construction debris left 
unattended 
- Bio-medical waste disposed in 
municipal stream /open areas 
- Segregation of recyclable waste at 
source not done 
- Primary collection of waste not 
done at place of generation 
Professors Colony, Patna - 2014
PRESENT STATUS OF WASTE MANAGEMENT……….. 
- Design and location of 
municipal waste storage depots 
inappropriate, resulting in 
littering of 
- Street sweeping not done 
everyday 
- Waste transportation done in 
open vehicles 
- Waste processing partially 
practiced in ULBs 
- Final disposal done through 
crude dumping 
- Rag pickers collect recyclables 
from municipal bins/dumpsites 
and litter the waste causing 
insanitary conditions 
Opposite A N College ,Yesterday
REASONS FOR IMPROPER MANAGEMENT OF WASTE 
• Lack of planning for waste management 
while planning townships 
• Lack of proper institutional set up for 
waste management, planning and 
designing in urban local bodies 
• Lack of technically trained manpower 
• Lack of community involvement 
• Lack of expertise and exposure to city 
waste management using modern 
techniques / best practices 
• Lack of awareness creation mechanism 
• Lack of Management Information Systems 
• Lack of funds with ULBs 
• Indifferent attitude of ULBs to levy user 
charges and sustainability 
Gardani bagh,Patna - 2014
II COMMENTS 
2) Residents 
A very unsatisfying collection Transportation A poor treatment 
 Lack of bins (80%) and bins 
are full 
 Poor collection frequency in 
some areas 
 No option for segregation 
 People manage their own 
way 
 Improper maintainance of 
vehicles 
 Insufficient number of 
vehicles 
 Open trucks spilling on road 
 Inappropriate treatment 
technology (Bairiya) 
 Lack of resources 
=> An overall dissatisfaction

2) Residents 
 improve the collection of waste, but 
also the transport and treatment 
 Improve manpower 
 East area neglected (no bins)

III GENERAL DISCUSSION 
1) Weaknesses of MSWM in Patna 
a) Factors related to population 
A huge population 
Lack of civic sense… 
… caused by lack of amenities and 
sensitization ? 9
III GENERAL DISCUSSION 
1) Weaknesses of MSWM in Patna 
b) Factors related to administrations 
Lack of facilities… Lack of awareness and communication… 
Caused by lack of organization 
-no studies on waste data 
-collection disorganized 
-lack of employees’ training 
-coordination between administrations

III GENERAL DISCUSSION 
2) Opportunities 
b) Integrated solid waste management 
More analyses : Life Cycle Assessment 
Waste management hierarchy and 3R 
-“cradle to grave" impacts of a product or 
service 
-Evaluation of MSWM environmental 
impacts 
-Help to identify options for waste reduction 
and recovery 
Waste to energy 
-80% of compostable : composting and 
vermicomposting are the best options for MSW 
-a low-cost method and viable (Sinha, 2014) 
-a very good fertilizer and protects plants “Gold 
from garbage”, vermifiltration 
-But segregation has to be done 12

IV RECOMMENDATIONS 
• Outsourcing of all activities under 
Solid Waste Management 
Services 
• ULBs to concentrate on 
segregation of waste at source 
• Waste processing like 
composting, bio-methanation 
should be done through public-private 
partnerships / private 
sector 
• Final disposal viz. sanitary 
landfilling to be done under 
public private partnerships / 
private sector 
• Bio-medical waste to be managed 
by Central Bio-Medical Waste 
Management Facilities.
RECOMMENDED APPROACHES TO WASTE PROCESSING & DISPOSAL 
I.WEALTH FROM WASTE (PROCESSING 
OF ORGANIC WASTE) 
(A) Waste to Compost 
(i)Aerobic / Anaerobic 
Composting 
(ii) Vermi-composting 
(B) Waste to Energy 
(i)Refuse Derived Fuel / 
Pelletization 
(ii) Bio-methanation 
II. Recycling of Waste 
III. Sanitary Landfilling 
IV. Treatment of Bio-medical waste 
separately
Waste treatment 
Type of waste determines the available treatments. 
• Mixed (MSW) 
– Incineration, Anaerobic digestion 
• Separated 
– Biological: Anaerobic digestion, Composting 
– Wood residue: Gasification, Incineration 
– Gray waste: Incineration 
– Recycling!
Incineration 
Materials are burnt, producing heat which is used to 
generate electricity. Toxic gasses have to be cleaned with 
various units and the solid residue is often mixed with 
asphalt. 
• Most applied technique 
• Pro’s: 
– Large capacity 
– Produces electricity 
• Con’s: 
– Requires advanced gas cleaning (especially gray waste) 
– Potential dioxines 
– Gas plume
Anaerobic digestion 
Biological degradation process which converts hydrocarbons into 
methane gas 
• Biomass and MSW can be used. 
• Produces electricity 
• Effluent from biomass digesters 
used as fertilizer. 
• Effluent from MSW digesters is 
mostly incinerated. 
• Relatively slow process, requiring large installations
Composting 
Composting is an established process which decomposes organic 
matter in biomass (only plant) via micro-organisms. 
• Product often used as fertilizer 
• Composting produces heat that can be utilized 
• Also evaporates water 
• Requires gas cleaning (often biological)
Gasification 
Gasification is used for woody biomass. Materials are 
indirectly heated producing syngas and woodcoal. 
• Biomass is transferred to electricity more efficiënt 
and cleaner than incineration 
• Closed carbon cycle, less polution 
• !Safety! CO, explosion.
Pyrolysis 
Releases combustibles from materials containing organic matter. 
Often plastics, rubbers, fat and oil fractions. Materials are 
indirectly heated in absence of air so combustion wont take 
place. Gaseous hydrocarbons are then separated and 
condensed into various fractions. 
• Requires high quality products to prove cost efficiënt 
• Requires advanced gas cleaning 
• !Safety! Explosion, harmfull gasses
Separation 
This is the key to effective waste management. 
In Austria 8 different waste bins are collected; separated plastic 
types, biological waste, plant material, paper and glass. 
Materials can be effectively recycled or processed, reducing 
landfillsize and raw material consumption. 
Mechanical separation techniques are also well established, 
however still funtion less effective than source separation

  • 15. IV RECOMMENDATIONS • Outsourcing of all activities under Solid Waste Management Services • ULBs to concentrate on segregation of waste at source • Waste processing like composting, bio-methanation should be done through public-private partnerships / private sector • Final disposal viz. sanitary landfilling to be done under public private partnerships / private sector • Bio-medical waste to be managed by Central Bio-Medical Waste Management Facilities.

  • 18. RECOMMENDED APPROACHES TO WASTE PROCESSING & DISPOSAL I.WEALTH FROM WASTE (PROCESSING OF ORGANIC WASTE) (A) Waste to Compost (i)Aerobic / Anaerobic Composting (ii) Vermi-composting (B) Waste to Energy (i)Refuse Derived Fuel / Pelletization (ii) Bio-methanation II. Recycling of Waste III. Sanitary Landfilling IV. Treatment of Bio-medical waste separately
  • 19. Waste treatment Type of waste determines the available treatments. • Mixed (MSW) – Incineration, Anaerobic digestion • Separated – Biological: Anaerobic digestion, Composting – Wood residue: Gasification, Incineration – Gray waste: Incineration – Recycling!
  • 20. Incineration Materials are burnt, producing heat which is used to generate electricity. Toxic gasses have to be cleaned with various units and the solid residue is often mixed with asphalt. • Most applied technique • Pro’s: – Large capacity – Produces electricity • Con’s: – Requires advanced gas cleaning (especially gray waste) – Potential dioxines – Gas plume
  • 21. Anaerobic digestion Biological degradation process which converts hydrocarbons into methane gas • Biomass and MSW can be used. • Produces electricity • Effluent from biomass digesters used as fertilizer. • Effluent from MSW digesters is mostly incinerated. • Relatively slow process, requiring large installations
  • 22. Composting Composting is an established process which decomposes organic matter in biomass (only plant) via micro-organisms. • Product often used as fertilizer • Composting produces heat that can be utilized • Also evaporates water • Requires gas cleaning (often biological)
  • 23. Gasification Gasification is used for woody biomass. Materials are indirectly heated producing syngas and woodcoal. • Biomass is transferred to electricity more efficiënt and cleaner than incineration • Closed carbon cycle, less polution • !Safety! CO, explosion.
  • 24. Pyrolysis Releases combustibles from materials containing organic matter. Often plastics, rubbers, fat and oil fractions. Materials are indirectly heated in absence of air so combustion wont take place. Gaseous hydrocarbons are then separated and condensed into various fractions. • Requires high quality products to prove cost efficiënt • Requires advanced gas cleaning • !Safety! Explosion, harmfull gasses
  • 25. Separation This is the key to effective waste management. In Austria 8 different waste bins are collected; separated plastic types, biological waste, plant material, paper and glass. Materials can be effectively recycled or processed, reducing landfillsize and raw material consumption. Mechanical separation techniques are also well established, however still funtion less effective than source separation
  • 28. YES Sanitation www.ancollege.org matters because our health is at stake ! THANKS
