INTRODUCTION This documentation has been written as a part of the IN:CH International Studio 2014 I Urban Subcultures. The aim of the documentation is to analyze the waste managment process of the university and make it an example for application in other universities.

For this reason the students worked with the Christ University in Bangalore and the Center for Social Action which is an association of the university.

The task for the students was to understand the source and disposal of all the different kinds of waste. What is already done within the system and how can it be improved and enhanced. For this topic a detailled analysis, the opinions from all the stakeholder as well from the employees, of the system was necessary. To understand this, several site visits were needed.

LOCATION Christ University founded in 1969, has a large campus with around 25 acres and is a part of the 100 acre Dharmaram College Campus in the center of Bangalore. 1 The Christ University, has taken a strong effort to establish the campus as a zero waste zone, through different scientific and environment-friendly measures. The slogan for the university is the everywhere known „reduce, reuse and recycle“.

WASTE MANAGEMENT OVERALL The Christ University has an awareness about waste management and handles their waste carefully and properly. At the beginning of the semester, the students are given instructions about this system.

The students get access to the waste processing units in the backyard and learn what happens with the waste they produce and how important segregation at the source is.

In this special education they visit the three types of the waste management system. There is the Sewage Treatment Plant (STP) which treats the waste water from the washing places. Further they see the wet waste processing which is done in two ways - the biogas plant as well as the composting plant. At the same location is the segregation area, where the women segregate the dry waste in 14 different types. Paper is already recycled on the site, and out of this they make different products for the students as well for the people outside the campus.

In all these places the students get detailled information and data, so that they really understand what is the process after their disposal in the dustbins.

In the following chapters will follow a detailed analysis of all these different waste management systems.

teens produce a lot of different kinds of waste. Their philosophy is to not let the waste out of the campus.

The university has established a system of primary segregation, in which the waste which is produced is collected in two different kinds

of dustbins. One for the dry waste and the other one for the wet waste, mainly produced in the canteens and kitchens.

This makes the secondary segregation much easier. Specialy to look

for is the mass of paper waste produced in a school. They produce daily around 75kg waste of different paper (coloured, blank, newspaper, etc.).

The wet waste which is produced by the canteens and kitchens is recyled totally in the campus area itself. The 420 kg of the wet waste produced by the university per day is used for composting or the biogas plant. They also collect wet waste from the theological college which is close to the same campus and use it in the biogas plant.

Nr. 04 : biogas plant | IN:CH 14

BIOGAS PLANT One biogas plant which can take around 1 MT of Wet waste per day needs an area of 500 m². The plant takes 1 MT of wet waste every day and produce 83.6 m³ biogas. This could be converted into 50 m³ Methane which can be used as bio diesel or converted into 193 kWh of electricity. There will be still some waste left, about 30%, but this can be used as manure.

Nr. 05 : small biogas plant | IN:CH 14

The basic process of a biogas plant: The wet waste gets collected in a collecting box after this it comes into a fermenter. It is around 20 – 40 C° in the fermenter and there is no fresh air and light so the microorganism can decompose the waste.

Biogas gets created during this process. Biogas consists of 60% Methane 30% Carbon dioxide and 10% other gases. 1 It is similar in the case of the analysed biogas plant. In a day, the plant takes a maximum of 500kg wet waste and produces 50m 3 of biogas. This biogas is used for cooking. The daily process needs 100-200 litres of fresh water. The main problem in this plant are the lemons and oranges or similar fruits which disturb the process.

The biogas plant does not generate any income, as the gas produced is used by the theological college for heating water for free. CSA and Parivarthana plan to sell the same gas to the college to generate income. For this reason, the biogas plant should be more controlled, which means more employees (one or two) only for this area. The space requirements is for a plant in this scale around 500 sqm.

Nr. 07 : composting plant | IN:CH 14

COMPOSTING PLANT Composting plants are used to recycle the wet waste and make fertilizer for the plants. The composting process takes 45 days. For the best result and to reduce the smell it is good to put different layers in the pits. For example, first a layer of dry leaves and on top of these a layer of foodwaste. After a while you have to mix it up and let the process continue. After 40 days the compost is nearly ready. After

Nr. 08 : composting plant | IN:CH 14

this you have to dry the compost for another 4 days and crush it in the crushing machine to powder.

The process is exactly like this at the Christ University. There are 4 composting pits with a capacity of 1‘300kg per pit. To fill up one pit it takes around 7 days. The 120kg per day comes from all the smaller canteens on the campus, except the Aman Rasoi canteen. For the dry leaves they have two large storages next to the pits.

The problems in this process are the smell and the drying area. There are a few good installations to handle the smell. They have a pipe below the pits which blows the smell out every day and second there is a coal filter above. This does not matter in the step, where the women have to take out the compost for drying. It smells very strong during this process. A good ventilation should be provided. The second problem is the drying area which is not covered by a shelter.

They have to dry the product in the sun on the street next to the composting area.

In the case study the plant generated in 2013 around 9‘500 Rupees with all the maintenance and salaries included.

SEWAGE TREATMENT PLANT In order to recycle and reuse the waste water, a sewage treatment plant is used. The STP treats the water in several ways, such as mechanical, with micro organism and if necessary with chemicals, until it is clean enough to reuse it for gardening and flushing. First the water goes through a coarse rack to take out the big solid waste. In the next step grease and sand gets segregated which is followed by sedimentation. After this the water gets treated by microorganisms.

Nr. 11 : sewage treatment plant | IN:CH 14

These two processes are repeated for several times and results in the final sedimentation tank. The STP reduces BOD5 (Bio Chemical Oxygen Demand) by 98% and the phosphate by around 90%. Even nitrogen gets reduced by 50%. 1 In the case study of the Christ University there is no recycling of the black water from the restrooms. They recycle only the grey water from the washing places and use it afterwards to wash the cars or animals and watering the vegetation on the campus.

Therefore a smaller STP is enough and some steps are not necessary, such as the chemicals. The STP on the campus handles 3‘000 litres a day. This on an area of around 1000 sqm.

The plant which exist does not generate any money but saves a lot of water. The yearly saving of water is around 1 mio. litres.

Nr. 13 : segregation area | IN:CH 14

SEGREGATION AREA Segregation is the most important part in the whole waste management process. Without this, the dry waste cannot be recycled properly. Therefore the people at the source or the waste producer should segregate at least the dry from the wet waste. There is further more segregation possible. There are a lot of people (mostly women) who have to do this work and segregate all the different types of dry was-

Nr. 14 : segregation area | IN:CH 14

te.

In the case study of the Christ University, there is a good segregation at the source. There are atleast two kinds of dustbins next to the canteens and kiosks, which have the category of waste written on them through pictures and text. The employees collect the waste three or four times a day from each dustbin. For this the campus is splitted up in three parts. After the collection, the women have to clean some of

Nr. 15 : segregated material | IN:CH 14

the dry waste and segregate it further in 14 different types. There are three different kinds only for the plastic, and the same for the paper.

The whole process takes place in a small area behind the recycling center. The women have to sit in the waste on the floor during the

RECYCLING Recycling is the last or afterwards the first part of the material. To keep the resources in the circulation it is necessary to recycle the usable dry waste.

Christ University recycles the exam papers on their own. There are overall 4 tons per year. Out of this they make different large coloured and patterned papers, which they sell as it is or they produce picture

Nr. 18 : machine | IN:CH 14

frames, diaries and other products out of it.

They unfortunately do not have the technique to recycle all the different kinds of paper. Therefore they would need other and more machines.

The recyling of the tetra pack is also well organiced by the Centre for Social Action. The tetrapacks are given to the organisation ANU. ANU produces a lot of different products, like bags, covers and others out of it. They give a part of them back to the school for selling. The earned money goes to ANU. Unfortunately there is no real market for these products out of the waste. So the buyers are mostly foreigners or the students in the school. There should be a market provided that out of this process can be earned more money.

„WASTE IS OUR VALUE“

The recyling how it exists now generates around 1.1 mio. RS in a year and it is possible to increase this with a better market situation for the products and maybe other products.

CONCLUSION The Christ University does a very good job in the sense of waste managment. But there are still some problems which are seen in the analysis.

1. Segregation at the source For this topic the students are designing a new kind of dustbin which interacts with the producers. The student or all the producers should not be forced to do the segregation but it should be „fun“ to do.

2. Biogas plant In this case, the process is well organized. Although, for a proper functioning at least one employee is necessary only for this part.

Further, it is a possibility to sell the biogas produced outside the campus.

3. Composting plant The composting plant functions well, but the working conditions could be made better. The ventiliation is interrupted by the storagehouse behind the plant. When this will be removed the air circulation can happen properly and the smell is no longer a problem. (Nr. 20) Another problem is the drying area which is on the street next to the plant. Therefore should be a special area provided for this.

4. Sewage treatment plant The reusing of the treated water is limited for washing cars or animals and the vegetation. This water can also be used for flushing in probably new buildings.

7. Overall The working space for the employees is not realy in a good atmosphere. It is uncomfortable to work around waste the whole day. The intervention for the women can be a recreation area behind their working space. This area can also include a rainwaterharvesting tank or a waste garden. Some area where they can spend short breaks.

Another good thing is, that this can be an expansion of the waste managment systems and can be showed to the students, so they learn what they can do with their waste at home.

There are only a few small interventions to improve the still well organized waste management process in the Christ University. If this effort will be aimed at all or at least more universities, the „problem“ waste will be minimized.

EXECUTION DUSTBIN The question is now why is there a need for a new dustbin in the campus. The main part where we want to intervene is close to the students. The students get a lot of information in the first semester, in case of what happens to their waste. But they only have to segregate the dry from the wet waste and the further segregation happens by the women in the backyard. And even this segregation

Nr. 29 : waste seen now | IN:CH 14

does not happen carefully, there are a lot of plates in the wet waste dustbins. So we want to increase their responsibility. The students should not have to think a lot about the waste, the segregation at the source should just happen. To keep the dustbin units as small as possible are there 4 different kinds of dustbins below the wastewall.

The further segregation will still happen by the women.

An other point of the intervention is to show at least the amount of waste everyday with a half transparent dustbin. So the waste pro-

CONCEPT The interaction should happen in different levels. There is the overall level in which the dustbin should invite and interest the people around that they go closer. For this reason is there the art installation which is placed outside of the cantenes and connect the system. In the second level are there the titels of the boxes on the dustbin. These boxes are for different kind of waste so you learn at the source to segregate. After that on the third level you notice the smaller letters which show you what exactly is to throw in this specific dustbin and why it is like this.

PROCESS We got at the beginning a more or less strictly defined exercise which we had to solve. So we started with the analysis of the whole Christ University campus and their waste management. For us it was clear, that there are only small interventions possible. So we began to plan the a dustbin which should be more attractive and interacNr. 36 : process 1 | IN:CH 14

tive. But further we thought about some architectural intervention in the backyard, where the biggest part of the waste management happens. But for the client it was clear, that they want for the moment no architectural interventions. Their wish was, that they get an new dustbin. So after several changes in the design we began to search a craftsman who can help us or more who we can help him in the execution. And finaly after some fights and discussions we could built our dustbin unit and additional a art installation which belongs

Nr. 37 : process 2 | IN:CH 14

to the whole unit.

REFLECTION In the whole process was the most difficult part the conversation inbetween the group, with the client and finally the different craftsmen. There were some misunderstandings which thrown us back in several parts of the project. An other difficulty was to search the right craftsmen. There are some which want to cheat us and finaly Nr. 38 : process 3 | IN:CH 14

there is one case where we got cheated. With the fast decision to spilt up the work in two parts, the upper part and the dustbins could we avoid worse. Because of the small time frame were there some parts which were not considered and we had to solve this directly on site with the craftsmen. The fact that we got the money directly from the client was an other point of this project. The responsibility was full in our hands and the BOQ was more or less always udated. What we did wrong was, to integrate the client just in the middle of the

Nr. 39 : process 4 | IN:CH 14

planning. This should be much earlier.
