NOSA Testing method now accredited for waste water
Access to safe drinking water is a basic human right and is vital to human health. The South African National Standard (SANS) 241 Drinking Water Specification states the minimum requirements for potable water to be considered safe for human consumption. This includes effluent water generated in multiple operations in myriad industries, including mining, food and industrial processes. In other words, any water used, treated and then tested following any of these applications must be clean enough that a person could potentially consume it without falling ill. These requirements include the microbiological, chemical and physical properties of the water. NOSA Testing’s ISO 17025-accredited laboratory service has increased its scope of accreditation to render the following water-analysis capabilities. Expertise includes, but is not limited to: • Heavy metals via ICP-MS and ICP-OES • Volatile organic compounds (VOCs) via GC-FID • BTEX (benzene) via GC-FID • Microbiological (pathogens and bacteria) • Total organic compounds (TOCs) • Chemical oxygen demand (COD) • Testing for trihalomethanes (THM) • Groundwater analysis • Borehole water analysis • Treated water analysis • Mining discharge water analysis • Waste water analysis • SANS 241 chemistry, microbiology, somatic coliphages and protozoan parasites Whether a company utilises water in its process, or provides water solutions, NOSA can provide further technical information on its waste-water analysis capabilities.
The kind of rubber that really matters
With the introduction of dual-compound rubber-soling technology in Africa, footwear can now offer better durability and more comfort Even when working in the same industry, employees often require footwear that is fit for different purposes with varying levels of protection. Traditionally, people working in extreme or hazardous conditions required footwear with a single-density vulcanised rubber sole, a nitrile rubber sole, or a dual-density polyurethane rubber sole. The single-density rubber sole can compromise on comfort as it makes for a heavy shoe with no midsole. The use of polyurethane rubber, on the other hand, results in a lighter boot that offers more comfort, but compromises on durability. Dual-compound rubber (DCR) technology, however, offers all the benefits with none of the compromises. It uses two different layers of rubber with the soles directly injected onto the uppers (the part of the shoe that covers the foot) for a superior bond that increases longevity. In DCR footwear, the polyurethane is replaced with a lightweight rubber to fight the destructive impact of hydrolysis, or the breakdown of chemicals, due to its reaction to water. The technology is ideal for environments with fluctuating temperatures and is resistant to 300°C direct and radiant heat, acids, oils and chemicals. It has superior slip, penetration and abrasion resistance, is shock absorbent and has a 100-percent waterproof sole. It’s ideal for use in the mining, oil and gas, heavy construction and engineering industries. This new technology can be found in the Bova footwear range. Peter Gerbrands, group marketing manager at BBF Safety Group, which manufactures and distributes the Bova range, says: “The challenge for us was to find a way to bring together the benefits offered by both the single-density vulcanised rubber and dual-density polyurethane soling technologies, while eliminating their shortcomings. “This technology is available through only a handful of manufacturers around the world, due to the complexity of the sole injection, and until now has not been manufactured on the African continent. This meant the DRC boots had to be imported, which made them expensive.” However, with Bova now manufacturing the product locally, it can offer the high-quality footwear at an affordable price. BBF Safety launched the new Bova range at the 2019 A-OSH Exhibition. The range includes a six-inch boot, two eight-inch boots, a shoe and Chelsea boot. Gerbrands comments: “Bova has earned a reputation for manufacturing safety footwear that is engineered for purpose rather than applying a one-size-fits-all approach.” With this in mind, the manufacturer plans to expand the DCR footwear range further with a specialist boots for extreme risk-associated environments with specialist applications. “It is our responsibility to constantly explore the products we release into the market and ask whether this is the best that we can offer our wearers. As technology evolves, it is our job to update our products to reflect the latest in safety footwear engineering, in line with market requirements and costs,” Gerbrands concludes.
Porsche sets factory benchmarks
Sports car maker Porsche has received a Platinum Award from the German Sustainable Building Council (Deutsche Gesellschaft für Nachhaltiges Bauen, DGNB) for its Leipzig plant. The facility, which covers 427 ha, was assessed in 28 categories involving 167 criteria, including environmental protection, biodiversity, energy management and its effect on the local urban environment. The award marks the second time a Porsche factory has won the DGNB’s Platinum certificate. In 2017, parts of the brand’s main plant at Zuffenhausen received similar status. Christine Lemaitre, CEO of the DGNB, says the car maker set high sustainability targets for its construction projects – and then met them consistently and transparently. Zero-impact factory Further, the company has revealed grand sustainability plans for the future: “Our vision is a zero-impact factory – we don’t want our production facilities to leave an ecological footprint,” says Albrecht Reimold, member of the Executive Board for Production and Logistics. He says that, since 2014, Porsche has cut vehicle-specific CO2 emissions caused by production by more than 75 percent and reduced energy consumption for each vehicle produced by more than 30 percent. Water consumption has been cut by about 20 percent. During the same period, the use of solvents has been cut by a third.

Our aim in terms of sustainability significantly exceeds mere decarbonisation,” Reimold explains. "We want to make sustainability at Porsche quantifiable and report it transparently, and awards like this are an important part of that," he adds.

Production is fully powered by regenerative energy sources, including photovoltaic systems, which supply power to the Macan and Panamera body shops, and a biomass plant to meet the requirements of a state-of-the-art paint shop. Since 2015, energy efficiency measures have saved a total of 23,3 GWh of power. The paint shop uses a rock meal filter system as part of a dry separator to collect unavoidable paint overspray. In line with a Green Logistics theme, Porsche operates its railway transportation with ecologically produced power, increasingly uses electric logistics vehicles, and has set up energy-efficient shuttle technology at a new, automated small parts warehouse. Compared with conventional small parts warehouses, the facility saves 676 t of CO2 annually. Holistic approach Production is not the only area of Porsche’s focus on sustainability. The manufacturer has implemented a unique children’s safari concept on its 132-ha off-road facility in Leipzig, which offers insights into plant and animal life. The environmental education project forms part of the company’s extensive corporate social responsibility commitments in culture, sports, education and social projects. “Acting sustainably means acting responsibly in terms of our staff, the local population around our sites and society as a whole,” says Gerd Rupp, chairman of the Executive Board at Porsche Leipzig.
