Rubble is a major issue for environmental and health reasons, and the problems with rubble are biggest where the demands for building materials are also biggest: in areas that recently experienced disaster. The recycling of rubble to new construction materials would thus be a major benefit for those regions. The Mobile Factory provides a new approach to recycling rubble. It converts the rubble left behind after natural disasters or wars to liquid concrete and puts it into blocks resembling 'Lego', which can be used for quick construction. The blocks themselves are also aligned with the principles of the circular economy, as it is possible to disassemble and reuse the blocks.

Demolition, war and natural disasters risk turning every man-made structure into rubble. Rubble is the world’s largest polluter in volume. It destroys the environment and it’s a health hazard for the people who are forced to live among it. Rubble typically occurs in places that are least equipped to deal with it. Following disasters that damage buildings, people are pre-occupied with rebuilding their homes and infrastructure, and the capacity to remove rubble tends to be lacking. At the same time, construction materials are in high demand, and therefore expensive and scarce.

The Mobile Factory is a small production unit that fits into two shipping containers, and breaks down rubble into liquid cement. From this liquid cement, the Mobile Factory creates bricks that resemble bigger, cement 'Lego' blocks. Those can be used for quick and easy reconstruction of damaged homes for the victims of war or disaster, while also clearing away rubble quickly. The buildings constructed with Mobile Factory bricks can also be easily disassembled, as the Lego-inspired system does not require any cement.
