JSE-listed Novus Holdings, formerly Paarl Media Group, has installed a biomass steam plant to power its Paarl Media Cape gravure printing presses. The plant was built and managed by renewable-energy company Sustainable Heating.
The boiler was powered by sustainable biomass, which burned at intense temperatures to generate the steam required to power the printing presses.
By using wood chips opposed to fossil fuel, coal or paraffin, Sustainable Heating’s boiler room produces steam for the printing process. By doing this, it does away with the high carbon emissions of fuel-generated steam. It also consumes minimal electricity.
Sustainable Heating CEO Paul Gorremans said the new printing facility would save about 218 000 t of carbon emissions over the next 15 years. The plant is 85% to 90% efficient, with fuel only being used to transport the woodchips.
The woodchip fuel used by Sustainable Heating was obtained from sawmill waste, as well as wood pallets that were chipped down to the right size.
Gorremans said world-class technology had been used on the project, which had taken 17 weeks to build.
He said he hoped to keep improving on this, with the goal of achieving 9.5 weeks for a full installation from foundation to first steam.
Novus Holdings prints most of the country’s newspapers and magazines, including You, Huisgenoot and Drum, and has 12 facilities across the country, with Paarl Media Cape being its flagship printing operation.
Novus Holdings group executive of sales Peter Metcalfe said the company had invested over R100-million in environmentally responsible practices.
“Various green initiatives and technologies have been put in place to reduce the impact of print production processes on natural resources,” he pointed out.
He added that the company focused on energy and water consumption, emissions and waste reduction, as well as boosting efficiency in production.
Metcalfe noted that Novus Holdings had also found a way of dealing with ongoing paper waste. Through its acquisition of a tissue manufacturing plant in KwaZulu-Natal, it had been able to transform the potential of waste paper into the production of toilet paper.
He encouraged other com-panies to consider renewable technologies.
Western Cape Economic Opportunities Minister Alan Winde said renewable energy was a game changer in South Africa. “We are working hard at our own carbon footprint and how we can help, from a leadership point of view, in creating a green future.”
He said he expected more biomass projects to be devel-oped in South Africa.
“If we . . . continue to build these plants that take biomass waste products, and start gener-ating better energy consumption, it starts to change how people think.”
