Sustainability, innovation and cutting edge environmental technology lie behind ambitious plans for the City of Sejong, a regeneration program made possible under South Korea’s future planning city banner status. Covering almost 73 km2 and combining striking architecture and innovative urban design features with wide-open living spaces and 400 km of bike tracks, Sejong city’s population is expected to increase from 30,000 people to 500,000 by 2030.
Its predicted density, in parallel with governmental plans to make Sejong the country’s second largest administrative city after Seoul, led to the decision to integrate Envac’s system within the fabric of Sejong city’s urban infrastructure.

Working in partnership with South Korea’s Land & Housing Corporation, Envac designed a system that will cater for 200,000 households, a park, public buildings and 69 schools on the development’s completion in 2030.
With an underground pipe network spanning almost 188 km, close to 3,500 outdoor waste inlets and the capacity to handle 140 tons of waste each day on the project’s conclusion, the first phase of Sejong City’s Envac system launched in 2015 and has already become an integral component in ensuring that the city remains clean and attractive to its current population, 11,000 of which are civil servants.
Sitting alongside other pioneering technology such as solar panelled bicycle paths that supply energy to 1,800 households, Envac is a beacon of sustainability that has helped Sejong become a national showcase of modern urban excellence.
Envac also helps to deliver a sustainable environment by working in partnership with the city’s waste contractors, which use waste transported by the underground pipe network to supply material for bio- and methane-gas power plants.
Since the system became operational in 2015 it has:
