The workshop was inaugurated by Dr. Rakesh Kumar (Figure 3). He briefed the delegates and

participants about the theme of workshop. He spoke about the history of waste management in India and

how management of municipal solid waste was neglected over the years when compared to other kinds of

wastes. He also highlighted different prospects of waste management in India in terms of existing

management practices, its challenges, policy issues, technological options and opportunities in terms of

waste to energy.

Figure 3: Dr. Rakesh Kumar delivering his Introductory Speech

Thereafter, distinguished speaker Dr. Sukumar Devotta (Figure 4)shared his comparative

knowledge of waste to energy from developed countries and how it could be implemented in developing

countries along with comparison of hazardous and MSW management systems in India. He also

highlighted the importance of mechanical, biological and other relevant treatment technologies for waste.

He concluded his speech by providing feedback on current Solid Waste Management and Handling Rules,

2000 and need for its amendment.

Then, Guest of Honor, Mr. R. A. Rajeev, IAS (Figure 5), shared his experience about the

management practices opted by TMC and the various challenges faced by them in its implementation. He

stressed on the fact that there is an urgent need to bridge the gap between existing management practices

and motivated municipalities and municipal corporations in India for implementation of effective

sustainable waste management in which Waste to Energy along with sanitary landfills should be an

integral part.

Thereafter, Prof. Ashok Pandey (Figure 6), expressed his views on the objectives of this

international workshop. The main focus of his speech was the understanding of available technological

options for waste to energy in India. He mentioned that developing technologies to treat mixed solid

wastes are collected in most parts of India to be very challenging. Subsequently, he highlighted the need

for source separation and technological options for the same. He concluded his talk urging for the

enhancement of capacity building at national and local levels with guidance from international

communities, interaction amongst experts, industries and municipal personnel on state of the art

technology and solid waste management system. He pointed out there should be an appropriate

technology for using waste as a resource.

Figure 6: Dr. Ashok Pandey delivering his Inaugural Speech

In the absence of Prof. Nickolas Themelis, Director, Earth Engineering Centre, Columbia

University, USA, Prof. Gunter Busch (Figure 7), Brandenburg University, Germany was the Chief

Guest. He shared the knowledge of existing technologies from Germany and other European countries

with their advantages and disadvantages in terms of economical and social aspects. He also suggested

some relevant small-scale technologies which may be suitable for Indian climatic conditions keeping in

view the per capita generation and the physical composition of solid waste.

THE MAJOR RECOMMENDATIONS OF THE WORKSHOP WERE:

The multiple levels of sharing of knowledge within India and also from other countries, set of

recommendations emerged. Though some of the issues could not be led to consensus, however, the need

to move ahead and move decisively and distinctly was clearly spelt out.

The status of MSW management in India has not improved substantially despite enormous

finding from JNNURM and other governmental grants. Smaller cities conditions are even more of

concern.

The MSW Management and Handling Rules need reform. Some of these need to emerge from the

areas of collection and transportation as a first step. Of the same, segregation needs to be

considered as a key component of the MSW management. In absence of segregation, most of the

downstream efficiencies are not achieved. The treatment/processing technologies have shown

poor results due to mixed waste receipts. The other area of reform is better monitoring of

odorous gases based on scientific rationale. The monitoring protocol based on population needs to

change as the emissions and odour are not linked with the population. In fact, the increasing

population makes it necessary that odour parameters are given more importance.

The technology mix needs to emerge from the characteristics of the waste and not on what

technology is available. The use of Waste to Energy concept must keep the basic principle that

we should burn what is combustible and use biological methods for biodegradables.

It was felt that there is a tremendous scope for the generation of energy from MSW and all the

municipalities must ensure the same. This would benefit the energy starved nations like India.

There should be proper technology assessment throughout the country which must address the

issue of climate (especially rains) and also the scale of the technology. There is a need to redefine

and document technologies applicable for smaller cities, large villages, whereas large metro cities

must address through technologies option of waste to energy, volume reduction and less land

intensive options.

The need was also felt that cities assessment across the country with regard to waste generation

and management needs to be undertaken periodically. The absence of reliable data makes all

MSW management decisions unreliable.

The health burden of poor MSW management started to pile up as number of diseases and its

spread has been seen to have direct correlation with waste management efficiencies.

Awareness must be created among general public and also among technology suppliers and

providers.

There is an urgent need of research and development in this sector, especially in following areas:

Biogas technologies (small scale and large scale); landfills of low-cost for smaller cities, recycle

and reuse benchmarking, combustion technology adaptation based on Indian MSW feedstock etc.

Currently, India is facing problems in terms of solid waste management and energy demand. A

solution must be chalked out in such a way that it becomes a win-win situation both in terms of

solid waste management and energy production.

Planning regarding urban waste management must be chalked out.

One could concentrate on decentralized system for management and treatment of solid waste in

urban cities.

Policies must be framed in such a manner that minimum quantity of solid waste must be disposed

at landfill sites. Since land is a scarce resource, government agencies must concentrate now to

plan for future. Also look at the options of reducing land requirement so that sustainability is very

high.

There should be more participation from regulatory bodies, policy makers through a regular and

proper public consultation.

Benchmarking of different issues regarding MSW management needs to be undertaken which

will address the service level benchmark. This would also help in performance based payment.

Service providers and also technology suppliers within India and also those with tie ups in other

countries are looking forward to transparent communication of policies for cities in terms of

technology use and their benchmark. The uncertainties are very high for new players who come

with technology and wish to undertake projects.

Odor control measures must be highlighted in policy framework and must get reflected as a

guideline without which acceptance of waste facilities would continue to be poor.

Roles and responsibilities of different organizations, public, and rag pickers must be formulated

in policy framework. Informal sector work must be recognized as they are responsible for a

minimum of about 8-10% of waste generated. They not only provide employment but also reduce

burden on the landfills. Their contributions need to be recognized.

The MSW process of decentralized management must also be examined and encouraged as they

prevent accumulation and also creation of a big problem.
