In the final webinar of its African Review-hosted 2023 campaign, Convergent Group explored its modern, eco-friendly concrete solutions for African projects
Such solutions – delivered to cut maintenance costs by eliminating hazardous silicate products – were showcased by company experts in the form of Jean-Claude Biard, SEO of Convergent Group SA; Mputu Schmidt, former CEO of Convergent Group SA and founder of Bondeko MB (exclusive distributor of Convergent Group in Africa); Carlos Garcia, technical and sales for ADI Group (Spanish distributor for Convergent Group); and Amritpal Singh Sura, external consultant for flooring treatments, former distributor of Convergent products in the Middle East.
“A number of projects we were doing in the Middle East required protection,” remarked Sura. “Longevity of protection requires a system which basically impregnates and becomes a densified surface as opposed to something which is topical and lifts off due to moisture migration. I found that being exposed to Convergent, it was important to stay focused on those systems in the Middle East. Jean-Claude, Mputu and I met several times in Dubai and there was emphasis on providing systems which were affordable and still ending up having a robust, lasting longevity of product. So you are not spending money all the time in order to maintain the finishes which you have already paid for.”
Over the course of the session, the participants guided the audience through the potential of cutting-edge lithium silicate technology for enhancing the protection of concrete surfaces, maximising cost-effectiveness and meeting sustainability targets.

Presenting on an African Review-hosted webinar, Martin Provencher, global industry principal for mining, metals and materials at AVEVA, explored the digital transformation of mining operations and its impact on sustainability.
“Sustainability is becoming a key aspect for mining operations,” remarked Provencher. “If we look at the latest EY research on the top ten business risks and opportunities for mining and metals globally in 2023, ESG remains at the top. Of course, most companies have environmental goals or are expected to reach a net zero emission by 2050, which is a pretty aggressive target. Many of them are targeting 30% reduction by 2030; seven years from now. So there is a lot of action that needs to take place quickly to get there. It is possible to get there, but we need to make sure we are doing this correctly.”
Fast becoming a huge part of ESG initiatives is fleet electrification where particular progress is being made in underground mines. While some countries are certainly more advanced than others here, Provencher noted that 40% of total emissions from the mining industry come from diesel trucks, making EVs a very attractive low-hanging fruit for companies to pursue.
There are, however, a number of challenges associated with bringing in electric vehicles which remains a barrier for introduction. One of the predominant reasons, is the limited range of EVs against diesel counterparts. To mitigate this, Provencher continued, data management is key and ensuring a strong grasp of real-time information coming in will show operators when machinery needs to be charged, allowing them to plan effectively for maximum efficiency on site.
Indeed, this is but a small advantage that digitalisation can bring to the mining industry as it grapples to meet ESG goals while achieving production targets. By getting a better grip of their data and using it to empower tools such as artificial intelligence, advanced analytics and machine learning, companies can achieve tangible benefits such as reduce downtime, enhance worker safety, cut operating costs and, of course, ensure compliance with environmental regulations and targets.
Through the course of the webinar, Provencher outlined this in more detail and explored AVEVA’s suite of cutting-edge software solutions, specifically designed to help mining companies make progress on their digitalisation journey and empower their operations.

The International Energy Agency (IEA) and the African Development Bank (AfDB) hosted the first ever high-level summit on providing clean cooking access in Africa
Co-chaired by Tanzanian and Norwegian government leaders, AfDB and the IEA, close to 60 countries alongside numerous companies and development institutions were represented at the Summit on Clean Cooking in Africa which took place in Paris.
Together, participants sought to take on the challenge that more than two billion people are affected by a lack of access to clean cooking, with more than half living in Africa. Here, cooking is typically conducted over open fires and basic stoves, making use of charcoal, wood, agricultural waste and animal dung as fuel. This can lead to harmful toxic fumes and smoke being inhaled – representing the second leading cause of premature death on the continent – and limits opportunities for education, employment and independence due to the time spent gathering fuel which is also detrimental to the environment.
President Samia Suluhu Hassan of Tanzania, commented, “Ensuring clean cooking access for all in Africa needs adequate, affordable, and sustainable financing for appropriate solutions and innovations; adequate global attention; and smart policies and partnerships. Successfully advancing the clean cooking agenda in Africa would contribute towards protecting the environment, climate, health, and ensuring gender equality. This Summit underscores our commitment to advancing this agenda and providing a framework towards universal adoption of clean cooking fuels and technologies across the continent.”
According to the IEA, the tools for enabling clean cooking access are readily available and affordable but progress in many African countries has lagged compared to other regions. It was against this backdrop that more than 1,000 delegates attended the Summit, to mark a turning point on an issue overlooked for too long. In Paris, approximately US$2.2bn was mobilised for this cause in financial pledges from both governments and the private sector.
Solving the clean cooking challenge
“This Summit has delivered an emphatic commitment to an issue that has been ignored by too many people, for too long,” remarked IEA executive director Fatih Birol. “We still have a long way to go, but the outcome of this Summit, US$2.2bn committed, can help support fundamental rights such as health, gender equality and education while also reducing emissions and restoring forests. And the commitments announced today go beyond the money alone – they set out concrete steps on how governments, institutions and the private sector can work together to solve the clean cooking challenge this decade. Going forwards, we will rigorously track the commitments announced today to make sure they’re met on time and in full – and continue to do our utmost to bring greater resources and attention to this critical issue.”
AfDB President Akinwumi A. Adesina, added, “At the African Development Bank, we are delighted to play a leading role alongside the International Energy Agency (IEA), Tanzania and Norway, to definitively tackle lack of access to clean cooking, that affects a billion people in Africa. In concert with countries, we will increase our financing for clean cooking to US$200mn annually over the next decade, while also scaling-up the provision of blended finance for clean cooking through the Sustainable Energy Fund for Africa (SEFA).”
Following the summit, the IEA has indicated that it will employ a ‘double-lock system’ to ensure that momentum behind clean cooking does not slow in the coming months and years. This will include using effective methods to ensure that pledges and commitments are fulfilled, tracking them carefully to make sure the money is spent in a timely manner and reaches those in need. In addition, the IEA will continue to play a convening role to engage more willing partners and generate new funds to help meet the US$4bn a year in capital investments required between now and 2030.
Prioritising clean cooking has been identified as a priority for the IEA in 2024. Find out more at: https://africanreview.com/energy/iea-prioritises-clean-cooking-access-in-africa
Rokbak, a ADT manufacturer, has provided a guideline on how to become a successful articulated hauler operator
Get ready to move:
Take control of the hauler and the daily work before the ignition has been switched on by making sure the truck is known inside out. It is important to have a thorough understanding of the truck's controls, capabilities and limitations. This includes knowing how to operate it efficiently and safely in various conditions.
Check things over:
At the start of the working day, prestart checks are essential. A diligent operator conducts routine truck inspections to make sure the truck is ready for work. They should check for pre-existing damage including identifying leaks and loose parts, the tyre conditions, lights and beacons are fully operational, full visibility through the windows and fluid and battery levels daily. Rokbak trucks have ground level test points and a fully tilting cab for quick, easy access when servicing. A thorough equipment walkaround before starting a shift can make a big difference, and it does not require a lot of time.
Know the limits:
Learn the worksite boundaries such as speed, ground bearing weight limits, travel direction, passing areas, width and height restrictions and no-go areas. Know the hauler’s capacity and ensure the truck’s working limits with regard to payload are understood. Furthermore, keep an eye on how many buckets the loader is dumping in the truck to stay within the safe operating limits of the ADT and avoid accelerated component wear through overloading. Rokbak provides an optional onboard payload system and exterior payload lights, which indicate to both the truck and loader operators whether the payload is on target or overloaded. This information is recorded and transmitted via the Haul Track telematics system.
Safe operation:
Follow all site operating procedures when driving the truck. Keep under speed and under control on gradients and check grade guides for safe and controlled descent speed. Correctly use differential locks – employing them when the operation is in soft or slippery ground conditions to maintain traction and control. Be aware of what equipment is on the haul route and what sort of traffic will likely be encountered.
Correct usage:
The Rokbak RA30 and RA40 articulated haulers have fully enclosed multi-disc brakes on all six wheels plus a retarder to deliver safe, consistent performance. Understanding the correct use of the retarder can prolong the life of the service brakes and reduce maintenance intervals for lower total cost of ownership (TCO). If required, make use of the transmission lock in range or manual shift modes to maintain a steady ascent or descent on gradients.
Stay alert:
A safe ADT operator stays alert to their surroundings, including other workers, vehicles and obstacles on site. They anticipate potential hazards and adapt their driving accordingly to maintain safety for themselves and others. Inevitably there will be challenges, such as navigating tight spaces. An alert operator can quickly assess situations, make informed decisions and take appropriate action to resolve issues while minimising downtime. Never operate an articulated hauler if feeling fatigued or unwell.
Keep an eye on targets:
Operating an articulated hauler requires attention to detail to ensure proper loading, unloading and manoeuvring of materials. While an integrated payload system can account for the number of loads moved, manually recording progress in relation to a target keeps productivity proceeding on schedule. For improved fuel efficiency, minimise heavy acceleration and aim to reduce unnecessary idle time whenever feasible.
Don’t ignore fault codes:
Critical information is delivered whenever system fault codes are triggered. If a Rokbak truck does develop a fault, the operator will receive a warning symbol on the dashboard. Faults should be reported when they occur as continuing operating could exacerbate the issue. Following the truck’s advice means increasing uptime by avoiding potential disruptions, and effective communication with site supervisors, co-workers and other equipment operators is crucial for coordinating tasks and ensuring smooth operations.
Finally:
At the end of a shift, follow the correct shutdown procedure. Allowing the truck to idle for a brief period at the end of a long workday enables the coolant to circulate through the engine. This helps to gradually lower the temperature, preventing potential damage from frequent ‘hot shutdowns’ over time. Adhering to the correct maintenance and start-up and shutdown procedures will help to keep operation costs low.

Benefits include all lead removed from the production process and from being released into the environment during application and the company is also investigating options for the reduction of plastics in the development of the new systems to further limit the environmental footprint.
Orica’s group executive and EMEA president James Bonnor, remarked, “This is the first time Orica’s electronic blasting systems are being manufactured at our new state-of-the-art facility in Sweden, close to customers in Europe, ensuring supply security and optimisation. The facility will initially be used to assemble Orica’s standard EBS detonators before it will become the world’s first assembly line for the fully lead-free electronic blasting range based on NPED technology. Trials with our customers will get underway in July – August 2024 and we look forward to continuing to explore how Orica can use innovative technologies to assist our customers achieve their environmental, social and governance goals.”
Field trials and testing will be conducted in the coming months following several years of development and it is expected that the new lead-free electronic blasting systems range will be available for shipment in Europe by early 2025.
