ZERO WASTE CAFETERIA
A zero-waste educational machine.
The basic principle of the design is to create a spaces from which the school goers can learn about waste reduction and sustainability. The building achieves this by the reuse of existing materials, integrate sustainable materials and recycle all waste. The materials have been chosen to enhance & protect, biodiversity and existing ecosystems whilst promoting these through design. Lastly, through the promotion of green living and education of how to be sustainable is at the forefront of the design.
A number of sustainable approaches are applied to the running of the facility in order to achieve the end-goal:
Bio gas is made from WC waste and used for cooking and heating
The sludge from the biogas reactor is distributed into wetlands and surrounding organic farming patches
Food waste is recycled by black soldier flies to breed larvae rich in protein which in turn goes to feed the fish in the aquaponics pond
A by-product of the black soldier fly larvae is natural fertilizer which is used in the vegetable gardens surrounding the building
A 5KW wind turbine works in tandem with solar panels to produce power whereby all excess power is returned to the grid
A conscious effort is made to minimize the amount of packaging and other waste brought into the building. The waste that makes it into the building is sorted and recycled by the students.
A green roof protects and cools the building from the harsh midday sun
Rainwater is harvested through the central roof section. It is led down through a pipe located in the central column and stored.
