Next generation tech tackles pollution


Next generation technologies present advanced new ways for both public and private sector to address waste and pollution challenges, experts say.

Speaking ahead of the upcoming workshops at Pollution and Waste Technology Africa showcase, experts report that 4th Industrial Revolution technologies and Internet of Things (IoT) systems can significantly improve monitoring and control of pollution and waste.

IBM scientist Tapiwa Chiwewe, a participant in the Pollution and Waste Technology Africa panel discussions, leads research on IBM’s Green Horizons air quality initiative in South Africa, which harnesses data from a range of sources and applies IBM computing and analytics, to measure air quality and even forecast levels and types of air pollution in future.

“In South Africa, national, provincial and local governments are committed to combating air pollution, and we have legislation and air quality monitoring stations in place in major metros. This puts South Africa ahead of many other African countries. However, resources are always a challenge, and there are not enough air quality monitoring stations. It is an important issue, since air pollution is a causal factor in a range of diseases, which could kill up to 700,000 people per annum,” he notes.

Chiwewe’s work harnesses next generation technology to support in-situ monitoring stations, extending the reach and impact of measures to measure and forecast levels of pollution, including particulate matter and ozone in the air.

“Following a data driven approach, we are gathering a range of available data and applying data science and artificial intelligence to make more accurate predictions about air quality,” he says. “So we look at all the historical data and forecast conditions in the future around diurnal trends, weekdays vs weekends and correlations between types of pollutants, for example. It is interesting that just by using the available data in new ways; we can now come up with reasonable predictions around specific pollutants in particular areas in future. This demonstrates the power of next generation technologies in managing waste and pollution.”

Chiwewe and a range of experts will participate in workshops at Pollution and Waste Technology Africa, where the role of next generation technologies in multiple fields will come under discussion. The talks will cover issues such as what the 4th Industrial Revolution means for waste and pollution; waste to energy; e-waste; innovative solutions for air quality management; mining waste and new technology; medical waste; waste water technologies and even the role of Google cars in measuring pollution.

“Next generation technologies such as IoT and big data analytics will play a growing role in managing pollution, waste and environmental affairs in future,” says Hanli Goncalves, Portfolio Director Hanli Goncalves of event organiser, Reed Exhibitions. “They stand to revolutionise industry, improve efficiencies and possibly even reduce costs. This is why our key theme across Pollution and Waste Technology Africa and the co-located Africa Automation Fair and Connected Industries conference this year is Industry 4.0/IIoT.”

Pollution and Waste Technology Africa will be held alongside Africa Automation Fair 2017 and the Connected Industries conference from 6-8 June 2017 at the Ticketpro Dome in North Riding, Johannesburg. They will focus on the changes wrought by the Fourth Industrial Revolution, assessing its global impact, the technology and infrastructural requirements behind the revolution and the impact it will have on efficiency and quality. Pre-registration for the Africa Automation Fair is free before 31 May, and registration at the door costs R100.

Traditionally attracting around 4,500 visitors, Africa Automation Fair is Africa’s largest showcase of industrial automation and control technologies.
