Key challenges associated with this proposed project included the following: Potential dustfall and particulate emissions from construction and operational activities, specifically: […]
Climate Change Impact Assessment
Rayten Engineering conducted a Climate Change Impact Assessment (CCIA) for the proposed extension of an anthracite mine in KwaZulu-Natal, as a required component of the Environmental Impact Assessment process. The CCIA assessed both the impact of the project on climate change and the potential impact of climate change on the mine’s future operations. The carbon […]
Air Quality Impact Assessment – Proposed Opencast Mine
As part of our commitment to supporting responsible environmental planning, we conducted an Air Quality Impact Assessment (AQIA) for a proposed opencast mining development in the Limpopo Province, South Africa. The objective of this study was to evaluate the potential air quality impacts from the construction and operational activities of the proposed mine on surrounding […]
Carbon Footprint Assessment – Water and Wastewater Treatment Facility
Rayten Engineering Solutions recently conducted a comprehensive carbon footprint assessment for a water and wastewater treatment facility in South Africa, covering one annual period. The assessment forms part of the company’s ongoing commitment to understanding, quantifying, and reducing its greenhouse gas emissions. Using methodologies aligned with the GHG Protocol’s Corporate Accounting and Reporting Standard and […]
Vanadium Ore Processing in Emalahleni
Problem/Challenge: An existing vanadium ore processing plant located in Emalahleni within the Highveld Priority Area—a region already burdened with poor air quality—posed potential air pollution concerns due to emissions from its operations. These included particulate matter (PM10 and PM2.5), sulphur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), ammonia (NH₃), and dustfall. Historical monitoring showed exceedances […]
Luanda–Malanje Railway in Angola
Problem/Challenge: The Zenza–Cacuso section of the Luanda–Malanje Railway in Angola faces significant operational issues due to degraded infrastructure, including numerous sharp bends, steep gradients, and damaged tracks and bridges. Thus, the Zenza – Cacuso section requires urgent renovation/upgrades involving sophisticated construction and engineering, to improve the existing line by introducing the necessary improvements. The proposed […]
Regional General Waste Landfill in the City of Tshwane
Problem/Challenge: The proposed development of a Regional General Waste Landfill in the City of Tshwane raised concerns about potential negative impacts on ambient air quality. These concerns stem from emissions expected during landfill operations, including dust, hazardous air pollutants (HAPs), and odorous gases such as hydrogen sulphide, ammonia, and various volatile organic compounds. The surrounding […]
Harbour/Port in Mossel Bay, South Africa
Problem/Challenge: One harbour/port in Mossel Bay, South Africa – although relatively small, hosts maritime and vehicular activities that contribute to air emissions. The challenge was to assess whether these emissions posed a significant risk to ambient air quality and nearby sensitive receptors, including residential areas, schools, and healthcare facilities. This assessment was necessary to ensure […]
