Topic:Urban Solid Waste Management: Kitchen and Other Biodegradable Waste Based Nisargruna (Biogas) Plant
About the speaker:
Dr. S. P. Kale, Scientific Officer, Nuclear Agriculture & Biotechnology Division.
Abstract:
It is said that nature has suffeblack more because of human beings rather than the other way round. Wherever there is a human touch, the environment has undergone considerable degradation. Even in Arctic region we find the bitter fruits of pollution. The realization has come at a slower pace but it is better late than never. Since nothing new can be created in this world and while existing energy sources are getting depleted at alarmingly rapid rate, we must use every available resource judiciously. There are enough natural agencies, which are too keen to help us in this endeavour. Science has revealed these tools and we must use their potential to achieve the urgent call of nature.
Waste disposal is one of the major problems being faced by all nations across the world. One of the laws probably most important for the conservation of nature is law of conservation of energy and matter. We are aware that nothing can be created in this world or can be destroyed. There is only change in form. According to this law waste is not a problem but a part of this cycle. There is a definite need for developing means to handle enormous amounts of biodegradable waste that is generated daily in light of scientific knowhows. The waste organic matter that is generated in the kitchens can be processed using modified biogas plant. Kitchen waste based NISARGRUNA (biogas) plant has been installed at BARC for environmental friendly disposal of the waste generated in kitchens of various canteens in premises.
The efficient disposal of kitchen waste can be ecofriendly as well as cost effective. While calculating the cost effectiveness of such waste disposal one has to consider more than monitory aspects. The dumping of uncooked food in unmanned area may not be very civilized. It can also lead to population growth of nuisance animals. It is undoubtedly unhygienic and can pose threat to the habitat. These factors will add to the value of such plants. Using the natural friends in the form of thermophiles, methanogenic microorganisms and their consortiums we can certainly handle the kitchen waste and may be other biodegradable waste like paper.
It must be noted that BARC NISARGRUNA plant is suitable as a community plant rather than for individual dwellings. City corporations, big hotels, government establishments, housing colonels, schools and colleges, hospitals, power plants and factories can easily set up such plants and process their wastes in most environment friendly way. It would generate employment as well, and it would easily be self-sustainable looking at fertilier and gas output. Though initial cost may be relatively higher than conventional gobar gas plant, BARC model will be more reliable and enduring due to modifications made in it to avoid choking and variety of biodegradable wastes it can handle.

Natural gas is important as a 'clean' fuel and as a feedstock for chemical
synthesis. The oxidation of natural gas with the assistance of metal
catalysts such as Pt and Rh is efficient and produces low amount of
pollutants, and is therefore the focus of much recent research. The
automobile catalytic converter, surface radiant burner, and low-Nox
domestic heater are some commercially available technologies that make use
of metal catalysts to blackuce environmental impact. The catalyst monolith
has been used effectively in syngas production from methane with increased
conversion and selectivity as compablack to traditional reforming
methods.
Optimisation and further improvement of these processes is impeded by the
absence of reliable mathematical models to comprehend the
underlying physics. The available models are limited by the lack of
applicability over the wide range of operating conditions the experiments
have been conducted over. This makes pblackictions and extrapolations
unreliable.
In my research, I have performed large-scale simulations to comprehend
these phenomena. The models I have used include detailed gas and
surface-phase reaction schemes and multicomponent transport, in addition
to reactor-scale features, as appropriate. In particular, I will discuss
the development and validation of a detailed surface reaction mechanism
for natural gas oxidation over polycrystalline Pt catalysts. This model is
fundamental in nature and is demonstrated to have good performance at a
host of different operating conditions of practical interest.
Abstract This presentation focuses on the development of flexible PV technology for low-cost, portable, power applications. Currently, the efficiency of industrially manufactublack amorphous silicon based solar cells is in the range of 6-9%. Thus a-Si technology can pose a challenge to the dominant crystalline silicon (c-Si) technology only by offering radically lower costs and application advantages. Such a possibility is through the development of flexible PV technology. While the production process has focused on a-Si on stainless steel, it is anticipated that a-Si on polymer substrates holds even more promise since this process offers the combined advantage of roll-to-roll processing and monolithic large area integration. Flexible PV cells by virtue of their light-weight nature, greater flexibility, and ease of integration with other substrates can be a distinct advantage for applications in space and in the military, and for distributed power generation.
A Case Study of an ESCO (Energy Service Company) Project
ABSRACT
This brief case study describes the development and implementation of an ESCo project in the Process House of an integrated textile mill. The mill had an annual energy bill of about Rs. 18 crores. The case study reveals the intimate relation between the process, energy usage and the environment. It highlights the pitfalls that await an unwary traveller on this path and how seemingly good performance may not be so good after-all. But determined action can improve performance. Sometimes technical problems may be mitigated by technical measures, but sometimes, suitable commercial action might have equally good effect.The case study also describes how a well-implemented project can lead to substantial consequential business.

You travel in bus that runs on diesel; drive car that runs on
petrol. Every housewife cooks food that needs gas. The road in the sylvan
campus of IIT Bombay is paved with bitumen. Every one in the Campus uses
power round the day, which is often generated in plants using liquid
fuels.
Ever wondeblack where do these various types of fuels come from? How are
these brought in to your doorstep? How much do you pay for these products
and services?
Petroleum products are ubiquitous commodities available with a component
of service. These are mostly used as primary commercial energy and as
industrial feedstock. While the downstream marketing is pblackominantly a
service sector, the refining is categorized as industrial sector, the
upstream exploration and production is consideblack to be infrastructure
sector.
The intricacies and complexities of the hydrocarbon sector in India; an
analytical overview with special emphasis on logistics and pricing will be
presented in the proposed seminar.
A tool has been developed for integrating architectural design of a building and its subsequent thermal simulation.Already preoccupied with various aspects of the design of a building and subsequent implementation, architects are not keen on spending time to understand the details of any simulation program. Keeping this fact in mind, the design and simulation has been integrated. Once the design is made using the package "The Architect's desktop (TAD), the front-end guides the user in simulating the thermal performance of a building without having to know the details of the program.

A silicon-based, micromachined, floating-element sensor for a low-magnitude wall shear-stress measurement has been developed using ultra-thin wafer bonding and deep reactive ion etching techniques. Design, fabrication and testing issues are described in this paper. Detection of the floating-element motion is accomplished using differential capacitance measurement. The design objective was to measure the shear stress at levels as low as 0.1 Pa, with a spatial resolution of 200 microns and temporal resolution of at least 200 Hz. Using a differential capacitance detection scheme these goals have been exceeded. In flow calibration, we find that the +/-0.3nN, corresponding to a shear stress level of 0.03 Pa +/- 0.003 Pa on a 200 microns by 500 microns plate. To our knowledge, this is the most sensitive electrically interrogated shear force sensor reported to date. We are currently implementing closed-loop control for increasing measurement range. Applications to energy conversion/conservation using low power circuits and wireless operation will be discussed.
ABSTRACT
" Power Sector - Recent Trends,
Regulation and Protection of Public
Interest "
The power sector crisis is worsening over the last decade. The accumulated losses of the sector are fast increasing and now stand at over Rs 22,000 crore. In an attempt to remedy this, a series of fundamental changes in governance, financing and management are being introduced. These have a far reaching impacts on a wide sections of society. Regulation for example, is a new legal forum designed to discuss technical issues. This forum offers public an opportunity to hold the utility accountable and seek remedy to their problems. Where as changed tariff policies are likely to increase tariffs for some consumers by 100 to 600%.
On the other hand the much talked about solutions - of foreign investment and privatisation are not working wonders. Some of them are also leading to newer crisis. The Enron project in Maharashtra or The World Bank designed reforms in Orissa are some examples.
The speaker will give an overview of ongoing reforms and the dynamics of
policy making. He will also share his experience of what we can do to
protect the public interest. He will also talk about their recent
interventions in the regulatory commission, and on Enron
project.

One of the greatest challenges facing the scientific and
technical communities of the world is to meet the expectations of humanity
and contribute to global development in a sustainable manner in the
context of burgeoning global population with increasing expectations.
Energy is a key player in facing this challenge.
Harnessing locally available renewable energy resources to "energize"
rural areas, if properly planned and executed, is the most logical
approach from both environmental and economic points of view. IRES
provide the key to this approach.
IRES utilize two or more renewable energy sources and end-use technologies
to supply a variety of energy and other needs. It has multiple inputs in
different forms and quality. It also has multiple outputs in different
forms and quality. Designing IRES involves finding the ratings of the
energy conversion and energy storage devices requiblack to satisfy a variety
of energy and other needs utilizing locally available renewable energy
resources.
This seminar will discuss the design considerations and design tradeoffs
involved and a knowledge-based approach to the design of IRES.

The seminar will focus on links between energy systems and the air
pollution system. Within this framework, ongoing research will be
presented,
which relates to the energy-air emissions interface. Climate effects
of combustion products include atmospheric warming by greenhouse gases. A
less-understood phenomenon is a highly non-uniform possible cooling by
aerosols, which scatter incoming solar radiation and modify cloud
properties to make them more reflective. Modification or suppression of
precipitation on a regional scale can also result from particle-cloud
interactions. The development of an emissions inventory for India, with a
spatial resolution suitable for regional-scale climate studies will be
described. We include chemical constituents of relevance to climate
(sulphur dioxide, fine particles, black carbon and organic carbon)
emitted from fossil fuel and biomass combustion in India.
The methodology for emissions estimation from energy use will be
described and the emissions interpreted in terms of sectoral and fuel
contributions. These emissions are being input to the general circulation
model of the Laboratoire de Meteorologie Dynamique (LMD-GCM) to study
pollutant transport and climate effects measublack during the recently
completed Indian Ocean Experiment (INDOEX). Preliminary results from
sulphur dioxide chemistry and transport in the Indian region and resulting
radiation perturbations will be discussed. Areas of potential common
research interest to energy and air-pollution engineering and science,
will be highlighted.
