The world is witnessing a paradigm shift. The transition from a linear to a circular economy may be about to drive the biggest transformation in business since the Industrial Revolution 250 years ago through a radical departure from the traditional 'take, make, waste' production and consumption models. We are going through the evolution to a circular economy, a socio-economic system which is smart, cross-sectorial and full of opportunities and challenges. SEMiLLA empowers this by designing circular systems such as our sanitation system.
