Emma graduated from Kingston University last year, where she developed her Green Pipe concept, which won an Award at the inaugural GREEN GRADS show last year. Her research showed that London has suffered from illegal levels of air pollution since 2010. Around 1.4 billion kg of air pollution are removed by vegetation each year; and, in the same period, even in dry districts, 24,000 litres of water could be collected from every roof. Her water collection and filtration panel system, bringing plants to underused vertical surfaces, attaches to gutters and directs water through the root system of plants growing on the panels. “Greenery can remove Co2 and other pollutants from the air,” said the designer. Her project will be shown on screen.
