Report on Educational Field Trip to Jindal Urban Waste Management Limited
On account of National science day (28/02/2025),an educational field trip was organized
for minor physics students, as well as first and second-degree students, to the Jindal Urban
Waste Management Limited (JUWML). The plant, which processes waste collected from
Greater Visakhapatnam Municipal Corporation, Srikakulam Municipal Corporation, Vizianagaram
Municipal Corporation, Amudavalasa Municipality, and Nelimarla Municipality, serves as a model
of waste-to-energy conversion. Students were given the opportunity to explore the waste collection
and processing methods, which are integral to the plant's ability to generate renewable energy from
municipal solid waste.
A key highlight of the visit was the process by which JUWML generates 15 MW of electricity from the waste it processes, with 13 MW being exported to the Andhra Pradesh Eastern Power Distribution Company Limited (APEPDCL) at a tariff of ₹6.22 per unit. The students learned about the plant's role in contributing to sustainable energy production and how it converts waste into a valuable resource. The project, with an investment of ₹340 crores, was funded by the Indian Renewable Energy Development Agency (IREDA) and the Indian Infrastructure Finance Company Limited (IIFCL), underscoring the scale and impact of this initiative.
In addition to learning about energy generation, students were introduced to the leachate treatment plant, which plays a crucial role in managing liquid waste from decomposing organic materials. This part of the visit helped students understand how waste management systems mitigate environmental risks by treating harmful leachate and preventing contamination of the environment and groundwater. The technology used in the leachate treatment process was explained in detail, offering valuable insights into advanced waste management techniques.
One of the most engaging parts of the visit was the interaction with the plant's large turbines. The students saw firsthand how mechanical energy is converted into kinetic energy, which is then transformed into electrical energy. This demonstration deepened their understanding of physics principles, particularly those related to energy conversion. Overall, the field trip was an educational success, providing the students with a practical understanding of how waste can be turned into clean energy, and inspiring them to explore the intersection of renewable energy and environmental science.
Van Mithra
On 28/02/2025 students visited Van Mithra instead of Thotlakonda as planned because of
traffic issues.It is an initiative focused on fostering environmental awareness and promoting sustainable
practices. The visit provided students with an opportunity to explore hands-on methods
of environmental conservation and sustainable living. Vanya Mithra, which emphasizes the importance
of eco-friendly solutions, offers a practical learning experience for students interested in the
preservation of nature and the promotion of green initiatives.
During the visit, students had the chance to observe and learn about vermi compost pits, a natural method of composting that uses earthworms to break down organic waste. This technique not only reduces waste but also produces nutrient-rich compost that can enhance soil quality. The students gained valuable insights into the benefits of composting and how it contributes to sustainable agricultural practices by reducing dependence on chemical fertilizers.
Additionally, students explored the various nurseries and plantations at Van Mithra, where a wide range of plants, including medicinal and native species, were cultivated. This part of the visit emphasized the importance of local plant species in maintaining biodiversity and supporting local ecosystems. Students observed the process of planting, nurturing, and maintaining plants, learning about the environmental significance of afforestation and reforestation efforts.
The overall experience at Van Mithra not only deepened the students’ understanding of environmental conservation but also inspired them to adopt sustainable practices in their daily lives. The visit encouraged them to think critically about waste management, the importance of green spaces, and how individual actions can contribute to a healthier planet.
Field Trip – Jindal Stainless Steel Limited, (S.Kota)
Department of Physics of St. Joseph’s College for Women(A) , Visakhapatnam went for a Field trip
with Students on 25th of March 2024, at Jindal Stainless Steel Limited S. Kota. Jindal Steel and
Power (JSP) is one of India’s leading business organizations with a significant production in steel,
mining, power and infrastructure. In this plant Stainless Steel is made from bauxite ore, iron ore, a
compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steel
making are mined and then transformed into steel using two different processes: the blast furnace/
basic oxygen furnace route, and the electric arc furnace route. There are 6 basic steps in the
Steel- making processes, which are as follows-
Iron-making
This is the first step in the manufacturing of pure steel. In this process, the raw materials like iron ore,
coal and lime are melted in a blast furnace. This results in the formation of molten iron, also known as
hot metal, which still contains 4-4.5% of carbon and other impurities, which makes it brittle. These have
to be subsequently removed.
Primary Steel Making
The remaining impurities are removed by either BOS or EAF methods. In the BOS method, recycled or
scrapped steel is added to the molten iron in a convertor. Oxygen is blown through the metal at high
temperatures and this reduces the carbon content to about 0-1.5%.In the EAF method, scrap steel is fed
through high-power electric arcs to melt the metal and convert it into high quality steel. The steel that is
obtained at the end of this step, by either of the methods, is called raw steel.
Secondary Steel Making
This step involves treating the raw steel in different ways to get different grades of steel. This may
include addition or removal of certain elements, and/or altering the temperature and the production
environment.The final grade of steel that is desired determines the further techniques that need to be
applied. These may include-
Stirring
Altering the temperature Ladle injection
Removal of gasses CAS-OB
4.Continuous Casting
In this step, the molten steel is cast into cooled moulds, causing the steel to harden. Using guided rollers,
the steel is drawn out of the moulds while it is still hot and then allowed to cool and fully solidify. Next,
it is cut to the desired lengths, depending on the applications-beams, slabs, billets, etc.
5. Primary Forging
In primary forming, the cut steel is formed into different shapes, generally by hot rolling, which
eliminates the casting defects and gives a desirable shape and surface quality. Seamless tubing, long
products, flat products and various other speciality products can be obtained by this process.
6. Secondary Forming
The final step is the secondary forming process, which gives the steel its finished shape and properties.
Various techniques can be applied at this stage, which involve-
Heat treatment (tempering) Joining (welding)
Shaping (cold rolling) Coating (galvanising) Machining (drilling)
Surface treatment (carburising)
The field trip was very exciting and knowledgeble and the students learned a lot of steel industry process
. Four faculty members were accompanied them. We are very greatful to the management for bearing all
our expenditure towards transportation etc., for the benefit of our students community.
