Our relationship with waste in today’s time and age, is from what we consume to the dustbin, rarely do we choose to know what happens to it after the ‘kachrawala’ collects it from our house. The blame for this lies with the boon of globalisation and urbanisation, wherein specialised systems are put in place, tending to man’s every beck and call. The downside of this though, is that these systems are rarely thought of in a holistic manner, one system is rarely intertwined with another, thus leading to discrepancies in functioning as a well organised and symbiotic network.
The most striking example of this is the case of waste management. Municipal Solid Waste (MSW) has to be managed by technologies and methods that enable keeping our cities clean, prevent pollution and protect the environment and at the same time minimize the cost through recovery of resources and energy. As per CPCB report 2012-13 municipal areas in the country generate 1,43,760 metric tonnes per day of Municipal solid waste, of which only 91,152 TPD waste is collected and 25,884 TPD treated. The MSW, therefore, dumped in low lying urban areas is a whopping 1,07,876 TPD, which needs 2,12,752 cubic meter space every day and 776 hectare of precious land per year.
Would waste management be a better system if it was thought of in a holistic way, wherein the waste we generate be used in a more productive fashion instead of taking up valuable space and causing serious environmental hazards?
In Pune, the Pune Municipal Corporation is in charge of the collection and management of waste. Currently, all of Pune’s waste is dumped in a massive landfill on the outskirts called Uruli Devachi. This has not stopped in spite of repeated protests and adverse health effects of the residents of the nearby town. Waste picker collectives like Swach are doing their part to contribute, but it is not enough. People have to start taking individual responsibility for their waste.
The need of the hour is to educate people and generate awareness about creating less waste. This project aims at developing a city level network of decentralised waste to energy power plants in each of the 16 administrative wards of Pune city that would also serve as context specific social space to make the service infrastructure accessible to the urban fabric and sensitise people toward the aim of generating less waste by incentivising responsibility toward waste.
Concept Development :
Swa-oorja (Swa: Self, Oorja: Energy) has the capacity to power 18,500 homes at an average in Pune per ward per day. This system will generate employment and revenue along with reducing reliance on the conventional hydro-electric system of power generation. It is scalable and hence is adaptable to various contexts and sizes, right from a housing society to a whole city. The programmatic challenge was to find the ‘sweet’ spot between industry, education and recreation, and the instinctive design response was to deconstruct the assembly line, which allows permeability of social functions without compromising on efficiency. Demystifying the industrial infrastructure was important, so as to design an architecture that addresses both its processing and social functions, and it is perceived as a social space first, before an industrial one.
Context and site study:
Kothrud ward was selected for a model for this system, as its population density to waste generation ratio is relatively high (6.7 sq.m per person). Kothrud also holds the record for the fastest growing suburb in Asia, transitively generating a massive amount of residential and commercial waste. The ward generates around 50 Tonnes per day(TPD) of MSW out of which approximately 40 TPD is organic waste. After studying the fabric of the ward, it was deuced that Kothrud had negligible public park space. Hence the power plant would double up as a public park. A former landfill site on an arterial road was chosen, which has a history as a landfill before it was banned in 1990’s, and is presently being used as a waste transfer station and office for Swach, the ragpicker’s collective. The site area is 27 acres with the road on the southern end, a hill to the north, and residential buildings on the east and west, along with a slum, that houses the swach employees to the southwest.
Site specific design decisions include water harvesting, two way vehicular circulation, deriving an axis from an existing temple. The role of the architect in this case is more as a designer of systems. The site has been developed as an overlay of various programmatic systems which translate themselves in geometries, them being:
- Plane: The surface on which the social activities take place.
- Organic line: Circulation on the ground, traced by the instinctive movement of people on the site, and the topography.
- Point: A grid of 20m x 20m has been laid on the site, with the grid points translating themselves into buildings, and the workflow tracing the gridlines.
- Process Line: The line tracing the grid, which the processes and services follow, and also translates itself into a pedestrian bridge, for visitors to access the processes without interrupting the workflow.
Programming the Plant:
The programme is divided into three parts, the power plant, which includes the waste to energy plant, processing units for dry waste, and an administration that includes a visitors centre and employee area. The social programme is designed as supporting functions to the power plant and include a shop for selling artisanal items made from waste, a cafeteria, a library and workshops that can be used to for a variety of purposes, ranging from studios for artists to hosting exhibitions. An art gallery has also been included, to encourage art. The third part is the permeable edge, on the southern end of the site, adjacent to the road, which relies on site specific design interventions, including a marketplace to replace the haphazard hawkers on Paud road, a community centre with public toilets and open space that the slum dwellers can use constructively. Adaptive reuse of the existing waste transfer station into an industrial jungle gym for children to play in. The existing Swach office has been used as a Nursery for toddlers and a cycle rent stand, while the office has been shifted to be a part of the administrative building.
Architectural language and material expression:
The prismatic form has been translated as a prototypical modular system of steel trusses, one module being 10m wide by 12m long, made from scrap metal. This module is repeated according to the usage of the building, with functions requiring less space made up of lesser modules and so on. Fly ash bricks are used for the walls, plastic bottles have been used as roof tiles and gutters, Bottle bricks have been used to make the seating, and reused oil drums have been used as lighting.
The aesthetic of the project has been designed to communicate a certain level of relate-ability, with the building form being reduced to platonic solids, prisms, spheres and cylinders, with the interpenetration between them make for the architectural language.
‘Architects have to become designers of eco-systems. Not just beautiful facades and buildings, but systems of economy and ecology, wherein we channel the flow not only of people, but also the flow of resources through our cities and buildings’ – Bjarke Ingles.
This quote sums up the concern for the project and the approach taken toward the thesis. Systems of living have to thought about in a holistic way, and the role of the architect in today’s time is a designer of these systems, since he has the foresight to perceive systems. Swa-oorja is an attempt at such a system, and it is designed to highlight and address waste management and power generation as cogs of the same wheel of sustainable living.

The industrial revolution provided us with the engineering and power necessary to make profound economic and social change. However, with this unprecedented growth and new found prosperity, an abuse of natural resources and our environment initiated a trajectory of unforeseeable consequences. Today, we are leaving our historically wasteful and turbulent manufacturing economy in favor of a seemingly more stable and mainstream digitally driven era. With this, we are seeing the massive areas of disrupted land that once stood to represent the height of innovation and success appearing as abandoned wastelands all over the world. With the quest to redevelop these areas lies the opportunity to re-imagine the definition of public space and green infrastructure.
This thesis takes a critical eye to previous and current design strategies of industrial landscapes and identifies new typologies relevant within this construct. Using a Gravel quarry with abandoned area as its site, this thesis proposes a master plan to reclaim, restore, and reuse the quarry as an alluring recreational green space for the surrounding community. In seeking a redefinition of the urban park, this thesis argues that a new type of cultural parkland is needed that envelope structures, that conversed and ground that responds to 21st century living.
This proposal uses a series of architectural interventions to respond to sites visual character and fill the recreational needs of the community. How can a forward looking architecture acknowledge a surrounding context defined by its past? This thesis aims to capture the knowledge of previous violent enterprise, physical industrial remnants, topographic qualities of a Quarried landscape, and the character of the surrounding community in order to fuse architecture with its industrial surroundings. Through this entwined relationship of architecture and its surrounding landscape the project is able to provide unique amenities that embrace the quarry’s industrial heritage. The proposal sees what has been abandoned not as waste, but as an opportunity to redefine the cultural park in order to create dynamic and engaging spaces.
“The modern park is no longer seen as a quiet rural green, but as a sparkling and overcharged urban crossroads” – AdriaanGeuze
Creating the Urban Landscape of tomorrow
The evolution of industries in the last quarter of the 21st century has been characterised by the abandonment of industrial areas. This trend is ongoing and is pushing rapidly toward urban areas. With this, cities are confronting change by reprogramming these postindustrial spaces, and people are changing their aesthetic sensibilities and attitudes toward natural and man-made environments.
By redefining these sites as public green space, we can capture the unique qualities and benefits of their industrial past to provide green infrastructure that hosts new architectural opportunities and amenities for its surrounding community. The recreational services provided by these sites will have both environmental and social benefits. The parks of tomorrow will become the basis of a thriving metropolitan culture. Parks implemented in these post-industrial areas will allow for shared experiences that give rise to mutual respect in the community and act as landmarks within our cities that represent growth and prosperity the way their previous industrial nature once did.
This thesis accepts the challenge that lies in incorporating natural processes into architectural interventions and looks to the land itself to identify design opportunities. The form and content of the pavilions and constructed landscape is developed through historical traces, local associations, indigenous plants, and regional materials in order to provide a new form of public space, while simultaneously embracing the identity of the monumental landscape defined by man.
