Current sustainable architecture and energy system is that the existing sustainable method to architecture is only concerned with only sustaining existing economic conditions. This only concerns the mere economic value and the standard and regulation are only estimated and based on Capitalism, which was the destructive concept that led to the situation.

This building is an urban recycling plant as a digestor of the waste from toilets and bio waste within the city, which aims to change the perspective and that notion of energy sources. The alternative energy sources are sludge and anaerobic digestion, both are from the human excrement and biowaste from the food and manure.

These are regarded as something to disgust to look at and its system is hidden under our current building system, which is always invisible. By distributing this view of discomfort and making fruitful energy from it, the building could potentially change the concept of discomfort, and eventually the discomfort can produce the comfort The forms of the sludge in the facade intervenes with the public with the public interface on street level and interacts with it, where the public can directly experience the scale of the sludge-meter.

The experience is caused by the sludge, as an ornamental material, and operating like a shopfront, which is run by the output from waste in the city. This building is moving from ownership to public access, and from markets to networks. There is nowhere for this waste to go beneath the ground or it cannot be removed through the conversion process.

This project seeks to undo the distinction between architecture practices and their context, by utilising the waste and the behind system to form a digester that could passively operate the buildings and the city.
