THEATRICAL WASTE SORTER CLUB from waste to commodity

The Theatrical Waste Sorter Club in Shibuya, Tokyo changes the public perception of waste to a valuable commodity by engagement of the public and theatrical propaganda. The design characters of each sorting layer determine a distinct club stage through the means of sound, light and space. To enter the club, dancers pay a waste bag as entrance fee. The thereby occurring waste sorting is a technological key for higher recycling rates. Afterwards the sorted wasted is collected again for reuse by citizens and the industry. The infrastructure significantly decreases waste production by shifting the public perception of waste and recycle more. Waste is now part of the personal circular nightlife, and its disposal no longer a disconnected end in the linear life cycle of a product. Furthermore, the emissions and congestion from curb side collection are reduced as well as the amount of collected waste, because most of the waste material is kept in a production cycle inside the city.

A material recovery facility has the following sorting steps: After the waste is tipped into a temporary storage area, it is sorted through four machines: A rotating disc screen to divert cardboard, then through an electromagnet to collect ferrous metals, through an Eddy current separator to repel non-ferrous metals and lastly, through an optical sorter to separate glass from plastic. Finally, it is compressed by a baler for transport to the recycling processes. The theatrical waste sorter club rearranges the horizontal sorting typology into a vertical tower to show the sorting steps as layers and the importance of gravity in the sorting process.

The Tenet of Ecology

The monocoque enclosure of the sorter materialises the design characters of theatricality, air pressure and noise to change the public perception of waste. Different waste types create different types of sound and light supported by the different sizes, acoustic and visual properties as well as materials of the monocoque modules. These modules are made from recycled aluminium, plastic and glass and are fabricated close to the site by the car production method of progressive metal stamping. Each sorting layer has its individual monocoque mutation varying in material, texture, scale, etc. according to its design characters.

LEARNING MOUND AA Exemplary Project 2020-21 ETS High Pass

The Learning Mound aims to intervene in London’s second CBD Canary Wharf, extend and expand its life beyond its working hours by introducing a vertical university campus focused on environmental studies as well as public programmes serving the local community. The expansion of demographics to students and academic staff will contribute to a more diverse community and district culture and the building to a sustainable future Canary Wharf. The building being open to the public enables the local community as well as office users to participate in open and free environmental education and wellbeing programmes before, during or after working hours.

The stepping of the slabs allows for an open base condition and houses the vertical park which continues in the sky gardens. The ground is characterised by a public educational plaza where the public and students participate in discussions and lectures. Furthermore, they relax by playing sports, enjoying the greenery or dining in a restaurant. The middle section becomes more communal with residential areas, smaller individual learning bubbles, communicative learning and tutorial spaces. A public thermal spa opens the top up again to the public.

natural ventilation and daylight on-site energy generation heat capture biodiversity generation

Environmental And Technical Studies 3. Design Project. As part of the ETS3 design project, I developed the Learning Mound to be as sustainable as possible with six environmental key strategies. These strategies are natural ventilation and daylight, biodiversity generation, heat capture from the underground. On-site tidal and solar power, rainwater collection and storage, and water reuse.

CARDBOARD AGGREGATE

Cardboard can be used for a lot of everyday items like packaging material or furniture. However, the material is really pushed to its limits as structural building material by Shigeru Ban who creates architecture with it. Typically he would use paper rolls as compression members of a truss in combination with metal nodes to connect them. The research question for my technical studies project was: Can the node become paper as well? Shigeru Ban’s nodes are metallic for a reason: They have to convey forces with multiple vectors in a very confined space. As cardboard cannot deliver that, the nodes have to become larger to the point that they constitute the whole structure and that there is only one element which does it all. The Institute for Computational Design and Construction (ICD) in Stuttgart has already developed something similar: Aggregation. Aggregation mimics the structural behaviour of granular substances like sand or gravel. Complementing the reuse theme of the course, aggregates are stable structural systems like a solid but can be disassembled and reconfigured without any waste like a fluid. Hence, my specific task was to develop a cardboard aggregation particle physically and test its properties in large scale aggregates digitally.

To illustrate the physical experimentation process, I always compared a potential improvement to the previous iteration by using the same method including the mould, pouring device, number of particles, etc., and changing one parameter.

Cardboard Aggregate

Further Learnings Though aggregates work theoretically only through compression, the barbs proved to enhance the stability significantly through tension. Miniaturisation of the particles also increased the stability. The cardboard sheets derived from a cardboard box and had crease lines which caused instability of the particles which crossed those lines.

Digital Experimentation

The Jitter Problem

To explore the limitations of the last physical iteration on a larger scale, a Houdini script simulated the aggregate behaviour. The constraints of the experiment were set as similar to the real world as possible. An external cuboidal mould and ground plane provide an operational space and the internal mould changed to be tested. The external mould was a bit larger than the spawning area to prevent the particles from spawning inside the mould and glitching into and through it.

The solver used in the Houdini script created a jittering effect. The particles moved and pushed each other so much that the aggregate always ended up approaching the ground plane. After a lot of iterations I managed to get the simulation partly working by adjusting a range of parameters including the frames of spawning particles, deleting the mould and reactivating all the particles, the shape, density, bounce, and friction of the particles and more. The simulation also made it possible to create impressions of spatial applications of the cardboard aggregate.

LIRIO

Project Lirio deals with the task of designing a self-sufficient city of the future. It identifies the functions of such a city and then placing it coherently in an urban planning concept. The project is located in the Geiranger Fjord in Norway, whose exposed cliffs and seclusion provide a logical environment for a self-sufficient city.

To emphasize the theme of self-sufficiency, Lirio hovers over the fjord, supported by a central pillar made of reinforced concrete, the stem. Cantilever arms, the petals, which house the residential quarters, fan out from this central axis. The vertical forces acting on the cantilevers are absorbed by tension cables leading to the stem. The horizontal forces acting radially to the central axis are caught by an annular tension cable. Between the petals above the pillar is a central light shaft, which ensures a natural ventilation and lighting of the megastructure. The diameter of Lirio and its height is 500m.

PARABRIDGE

In the course structural design I developed an arched bridge which is suspended from three arches that converge under the bridge to form a continuous girder. Grasshopper makes it possible to define a structurally and functionally reasonable geometry of the road surface dependent on the arc. The basic principle is that the suspension ropes follow the vector of curvature of the arc to provide the optimal load with a minimal bend in the arch similar to the Weinberg Bridge in Rathenow by Schlaich Bergermann Partner.

BETWEEN PLATES

“Between Plates” provides a widely visible monument for the attraction of the Grjótagjá caves and their geothermal pools. Following a circular trail around the fissure between the European and American plates, visitors reach the café with an integrated waiting area. After refreshing themselves, they enter the stairs along the meandering rustic corten steel wall. While climbing the stairs, the tourist‘s view is restricted to the beautiful surrounding landscape. At the moment they pass the opening into the space between the two large corten steel walls, their sight is guided along the fissure. The visitors travel from the American plate through a threshold between the tectonic plates to the European plate. The names of the plates are impressed into the walls to visualise the transition. On the European plate, the traveler arrives at the hot water of Karlagjá cave. Finally, they complete the circular path to the parking area.

During my internship at Gasteiger Architekten in Munich, I could participate in various high-end housing projects in and around Munich. I drew a lot of details and learned much about structures, dimensions and standards that way. I also helped wherever there was something to do, e.g. in model making, other plan drawing than details (floor plans, underground parking, etc.) or customer talks. We often visited the construction sites so that I could get a real impression of what I was drawing.
