Swedish consortium promotes Chinese sustainability

IVL Swedish Environmental Research Institute has joined Scania, Xylem and Malmberg in a new consortium to promote sustainable urban development in China.

The consortium will, together with Chinese partners, aim to solve the challenges that Chinese cities are facing with severe air pollution and an increasing need for sewage treatment and sludge disposal. The signing of the new association took place in the presence of the Swedish Minister of the Environment Lena Ek and Zhao Yingmin Director General for Science and Technology, Ministry of Environmental Protection, at the Sino-Swedish Seminar on Environmental Technologies for Future Cities that was held in Beijing.

According to IVL, the four companies will offer solutions for work in areas such as wastewater treatments and sludge handling.
“…sludge must be recognized as a resource which contains large amount of organic matter and nutrients, as well as energy. It is estimated that about 100 terawatt-hours of renewable energy is wasted every year in China,” said Östen Ekengren, Vice President of IVL, in a press release.

Furthermore, Chinese cities also need to build modern, attractive and economic public transportation systems. In order to reduce local emissions many operators use natural gas as vehicle power, especially the taxi in city. IVL states that this means that biogas easily can replace natural gas as vehicle fuel in China, which could achieve up to 90 per cent reduction of the emissions of carbon dioxide, particulates and nitrogen oxides. Another way to reduce emissions and to reduce road congestion is to attract more people to take public transports. The consortium will also offer modern city buses that will attract passengers thanks to their comfort, low emissions and safety. For the city bus operator these buses offer much better operating economy than available in China today. The better operating economy is a combination of using the best drive line and cheap locally produced biogas.
