Danielle Coffey — a graduate from the Northumbria University in New Castle upon Tyne, England, has pioneered a new soap-making method that is inspired by the movement for sustainability and conservation of resources.
The device is mindful of food by-product waste. Dubbed 'Sápu' (which means 'soap' in Icelandic), the gadget operates on fat, oil, and grease waste. Through an intricate process, Danielle Coffey's project turns this input into usable, natural soap. Aside from being able to make your own cleaning products, the soap-making method ensures that the excess oils, fat, and so on do not pollute drinking water.
Danielle Coffey's 'Sápu' is also an attempt to "instill behavioral changes" in users, making them aware of the importance to use and reuse.
