and biomethanization are found to be more suitable. Although the pollution problems are associated with
incineration but it can be made viable for handling small amount of waste, If due care is given to the treatment of
flue gases [2]. Similarly biomethanization is recommended for small quantities. The gas obtained from
biomethanization can be used for power generation purpose [4]. As the amount of entire waste generation for
Delhi is as high as 9000 MT per day it can alone not be dealt by using any one method only. But incineration and
biomethanization are method which reduces the load on Sanitary Land Fills [4]. The proper segregation of solid
waste at the source itself will enable us to extract higher amount of energy at a considerable low cost as well as it
helps us in producing a high quality compost. During the survey at Balswa compost plant wecame to know that
the composting plant is underutilized due to the poor quality of waste reaching to dump site (Plant capacity is
500 MTPD and it operates at 300 MTPD).The need is to make the public aware of the fact and to operate on an
efficient waste collection and utilization mechanism [6]. In order to exploit the solid waste as a source of energy
the steps are to be taken by ULBs and the participation of private sector as well as that of the RWAs and NGOs
is must for the success of WTE application [3]. If we do not take the necessary steps on time we shall be facing
the problem of public hygiene as well as the deterioration of environment [8]. There is a considerable amount of
energy content which can be extracted from the domestic solid waste, but we are deprived of this because of the
fact that we are not able put the ban on rag picking. Also there is no accountability of govt. officials deployed for
the solid waste management [7].
The complete elimination of SW is not possible at all, so the emphasis should be on its proper management.
Certain suggestions to improve the situation are as mentioned below:-
• Commercial establishments and road side vendors must ensure for safe disposal of SW.
• Participation of NGOs and RWAs is to be encouraged.
• Government should have a strict supervision on recycling plants.
• Public Awareness through hygiene camps.
• Encouraging separate use of separate containers for biodegradable and non biodegradable waste
segregation at source. Garbage should be transported in covered vehicles.
• Open disposal of waste is to be banned and ensuring the segregation at the source.
• Introduction of sanitation course at school level.
• Developing nodal energy centers for institutional MSW to handle and WTE generation.
• Funding and subsidizing the loans for implementation of such projects.
Acknowledgement
We acknowledge our sincere thanks to the residents of SAHARA II, and RAJMAHAL -- II, for their support in
conducting the experiment and providing us their domestic solid waste on regular basis. We are also thankful to
the staff deployed at composting plant at Bhalswa for providing us the valuable informations.
