Northumbria University graduate Danielle Coffey has designed a device that transforms oils and fats leftover from cooking into soap, to prevent them from polluting household water systems.
Sa?pu, which is Icelandic for "soap", is a kitchen product that aims to encourage homeowners to collect and repurpose their own fat, oil and grease (FOG) waste from cooking by turning it into natural soap.
Developed as a more environmentally friendly alternative to sink disposal methods, the project aims to address the pressing future issue of water pollution.
Once filtered, lye and water is added to the mixture During her research, Coffey found that FOG blockages are responsible for around 80 per cent of water-system issues, and approximately £100 million worth of damage to systems and the environment.
She also discovered that incorrect disposal of pollutants by households are the biggest contributor to blockages in the water system.
Therefore, with her Sa?pu project, she aims to improve future water quality by "instilling behavioural changes" that will encourage people to correctly dispose of or reuse FOGs.
