What if the waste we produce was put back into the energy cycle?
What if a petrol station was not a petrol filling station but a place where our waste could be transformed into organic forms of energy?
Compost Station occupies the site of a current BP petrol station, which by its nature is a hotspot of pollution and promotes a car-based lifestyle. It is designed to transform the food waste of the residents of Acton Central Ward into energy: green energy they can use themselves. The building is composed of two key elements. In one, compost is digested using wormeries located in repurposed petrol tanks. The organic material disintegrates into two key components: biogas and fertilisers. The biogas is turned into electricity in power generators, while the fertilisers are stored for further use in the garden and greenhouse. The second part of the building consists of a greenhouse and work cafe that utilises the energy generated in the compost house. The fertilisers are used to grow vegetables for the local community. The site is designed to be a place open to everyone, a place for neighbours to socialise and that promotes a pedestrian city.
Thick rammed earth walls form most of the façade and are raised on brick plinths. They are supplemented by a lightweight timber-framed greenhouse structure that cuts into it.
The main compost drop-off point consists of a light timber structure and large, see-through containers that are connected to the underground composting chamber with wide pipes.
Compost station is composed of two key parts. The compost and energy-generating part is located underground with the public cafe and greenhouse rising above it.
This section shows how compost is directed from the drop-off point on the left to the composting chamber, biogas-generating tank, biogas storage tank, energy generator, electrical box and kitchen right above it.
