Same trusted intelligence, smarter footprint: Hexing unveils the feature-rich smart meter A s utilities and municipalities across the region accelerate their grid modernisation efforts, space kiosks requires technology that is both physically adaptable and future-proof. Responding directly to this market demand,
are getting the identical, high-performance technology they rely on, with absolutely zero compromise on features, security, or metrological accuracy.” Next-generation security and grid control While the meter maintains the trusted architectural DNA of the standard HXE130, this compact variant is built for the future of utility operations. It natively supports STS2.0, ensuring compliance with the latest encryption standards and providing a secure, seamless transition for utilities managing long-term token identifier (TID) rollover strategies. Furthermore, the integration of advanced load-limiting functionality gives utilities a powerful tool for demand-side management. Grid operators can now dynamically manage peak demand and protect localised distribution infrastructure directly from a compact DIN-rail footprint. Integrated LCD and modular comms Historically, shifting to a tighter DIN-rail footprint meant sacrificing user interface clarity and communication flexibility. Hexing’s engineering team has shattered that convention by introducing two major design milestones for this product class: First-in-Class Integrated LCD Display: For the first time in Hexing’s DIN-rail meter range, a full LCD screen is built directly into the face of the compact unit. This allows field technicians and consumers to view critical metrology data, consumption metrics, and status codes effortlessly at the point of installation. Novel Modular Communication Options: In a true breakthrough for a form factor this compact, the meter features a fully modular communication slot. Utilities are no longer locked into a single communication medium; they can hot-swap modules to support varying field requirements—whether utilising PLC, RF, or cellular networks—without replacing the meter asset itself. “This is about giving our partners the flexibility to standardise their technical deployments across vastly different environments,” Faisal explains. “We have achieved something truly novel at this footprint by integrating both a clear LCD display and a fully modular communications architecture. Whether you are managing complex token upgrades with STS2.0 or swapping out communication modules as your infrastructure evolves, this meter delivers. We’ve compressed the hardware, but we’ve significantly expanded the capabilities for our customers.” Seamless integration, proven reliability For technical and engineering teams, the introduction of new hardware often brings the headache of backend system overhauls. Because the internal architecture, metrology circuitry, and core firmware of the DIN- rail variant align with the trusted HXE130 platform, it integrates smoothly into existing systems. Head-end systems (HES) and Meter Data Management (MDM) platforms will interface with the compact unit seamlessly, preserving existing vending workflows and security keys.

Industry expertise drives SEW-EURODRIVE’s presence at Electra Mining Africa
Motor protection relay solutions I n today’s demanding industrial and commercial environments, reliable motor protection is essential for maintaining uptime, ensuring safety, and maximising asset lifespan. For electrical contractors working with low- voltage (LV) and medium-voltage (MV) systems, selecting and implementing the right motor protection relay solutions is critical. Understanding motor protection relays Motor protection relays are specialised devices designed to detect faults and abnormal operating conditions in electric motors. They provide protection against hazards such as overloads, phase failures, unbalanced currents, ground faults, and locked rotor conditions. Modern relays offer much more than basic protection—they integrate monitoring, diagnostics, and communication capabilities, helping contractors deliver smarter, safer, and more efficient solutions to end-users. Key features and benefits For LV and MV applications, relays must be selected based on system voltage, motor size, and application-specific requirements. Digital motor protection relays, in particular, bring several advantages: • Comprehensive protection: Advanced relays monitor multiple parameters, including current, voltage, temperature, and power factor, ensuring rapid detection of abnormal conditions. • Reduced downtime: Fast-acting trip mechanisms help isolate faults, minimising damage and reducing repair times. • Remote monitoring and control: Many modern relays support communication protocols such as Modbus, Profibus, or Ethernet, enabling real-time monitoring and remote operation—ideal for facilities with centralised control rooms. • Integrated diagnostics: Built-in event and fault logging help contractors and maintenance teams analyse issues quickly, improving troubleshooting and system reliability. Implementation considerations When installing motor protection relays, contractors should focus on proper sizing, correct wiring practices, and seamless integration with existing control systems. For MV systems, considerations such as insulation coordination, CT/VT selection, and arc-flash mitigation become even more critical. LV installations benefit from compact, multifunctional relays that fit easily into standard panels and offer plug-and-play commissioning. Conclusion Motor protection relays are indispensable for safeguarding motors in both LV and MV environments. With the increasing complexity of modern electrical systems, contractors should prioritise advanced relay solutions that combine robust protection with smart features. By doing so, they not only ensure regulatory compliance and equipment longevity but also deliver greater value to their clients through improved safety and operational efficiency.
Smarter technologies and modern engineering solutions are helping industries improve efficiency and competitiveness.
A ccording to Jonathan McKey, National Sales & Marketing Manager at SEW-EURODRIVE, industry- specific focus and life cycle support are the standout features of SEW-EURODRIVE’s presence at Electra Mining Africa 2026. “Our exhibition stands will demonstrate how we partner with customers across the full operational lifecycle – from new installations through to maintenance, upgrades, optimisation and long-term asset management,” McKey says. “The overarching message is about business integration and modernisation to help customers progress along their sustainability and productivity journey.” He highlights that SEW-EURODRIVE has expanded its offerings not only through exciting innovations in equipment and solutions but also through services that assess customers’ existing infrastructure and enhance it to enable more efficient, productive operation. This philosophy shapes both of the company’s stands at the show. “Visitors to our main stand in Hall 5 will appreciate the industry-focused layout, which facilitates conversations that are both relevant and technically focused,” he explains. “Instead of a generalised display, visitors will be able to engage directly with specialists aligned to specific sectors, including mining, materials handling and logistics.” To enhance the value of these vital face-to-face discussions, SEW-EURODRIVE will have management and technical experts on hand throughout the exhibition. Dedicated meeting areas will also facilitate more private discussions on operational challenges, project requirements, or longer-term strategic partnerships. At the company’s second exhibition stand in Hall 4, SEW-EURODRIVE will focus on its electronics portfolio and showcase its on-site energy surveys. The company’s experts will demonstrate how they use advanced tools to conduct these surveys and the key benefits they deliver. “We will unveil selected new technologies at our stands, focusing on how this innovation is driven by customer need,” McKey says. “We avoid promoting products for their own sake; rather, we use these forums to ask visitors about the technical challenges they face, and then we design our solutions to address them.” This extends beyond physical equipment to include digital tools, training, service agreements and maintenance programmes. SEW-EURODRIVE will also showcase its training, digital solutions, after-sales and maintenance services. “Another theme of the exhibition will be the modernisation of existing plant infrastructure,” he says. “This is particularly relevant to mining operations,
where legacy equipment often remains in service for decades.” While older systems may still be functional, their performance may be compromised and their cost- effectiveness suboptimal. SEW-EURODRIVE increasingly works with customers to evaluate existing installations, compare them with current technologies, and identify opportunities for improvement. This can include energy surveys, drivetrain assessments, maintenance reviews, and broader operational optimisation studies. “We can modernise those products, extend their service life, and make an impact across multiple facets of a customer’s business - including running costs,” he says. “We can enhance all of that by modernising the plant with technology.” Importantly, the company aims to reduce the disruption often associated with upgrading legacy infrastructure by using specialised solutions to streamline the transition and mitigate risk. Another key talking point across the stands will be SEW- EURODRIVE’s growing service capability in South Africa, including expanded aftermarket support, reverse engineering and repair services. This capability extends beyond servicing its own products to include other OEMs’ equipment. “Our recently expanded facilities in Aeroton, Johannesburg, have further improved our service capabilities not only for our own product but also for non-SEW products,” he says. “With our depth of technical expertise and specialised workshop equipment, we can reverse engineer and repair obsolete products, restoring them to working order.” By visiting SEW-EURODRIVE, Electra Mining Africa visitors can begin a holistic discussion of their current operational demands and future plans for their specific mine or industrial plant. The experienced SEW- EURODRIVE team on hand at the exhibition will help chart the path to improved asset performance. “Our presence further underscores that mining remains a major global growth sector for us, especially as mines look for ways to extract minerals from the ground more efficiently,” McKey says. “This pressure is accelerating demand for modern drive technology, automation and broader operational optimisation, which are the areas where we see growing opportunity.” McKey also expects strong interest from Electra Mining Africa visitors in infrastructure development and asset improvement more broadly. He notes that SEW-EURODRIVE is increasingly involved in projects that not only support industrial operations but also help modernise economies through better engineering, improved reliability and smarter technologies.

Powering your operations across Africa with trusted technical expertise A manufacturing plant needs a steady- state generator set that can power sensitive CNC machines with stable by visiting the site. We gather detailed information around power demands, peak loads, and the equipment that the
shelf model to more elaborate equipment and configurations, including synchronised units for large-scale power generation and careful integration with site equipment and infrastructure. An experienced generator provider collects these details and collates a site’s multiple requirements. Typical customisation options include the generator’s power output capacity, fuel type, noise reduction, control system, and size. Balancing these against budget, performance, and environmental expectations is complex, which is why the value of an experienced customiser shouldn’t be underestimated. For instance, a remote mining site requires generators to support emergency dewatering operations. These generators need to be hardy yet mobile, hold enough fuel for long-term operations, provide remote-monitoring features, and also be easy to refuel. They need to be cost- effective, and the customised units must be delivered quickly. Such a project has several competing requirements that can undermine the generator set’s value and performance. The generators might be too cumbersome to move as the dewatering operations shift focus. They might use the wrong fuel or require frequent maintenance due to dust and moisture damage. It’s the generator customiser’s job to understand such issues, says Kotze. “We conduct assessments to understand factors like environmental and operating conditions, which we might get from the client or
generators will power. We try to speak to all the stakeholders. Customising generators is our second priority. Understanding the project’s requirements from different angles is our first priority.” How to select a customisation provider Customising a generator requires more than technical skills. To evaluate a generator provider’s customisation service, start by looking at their track record. What is their experience with similar projects, and what references and case studies do they provide? Are they asking the right questions, showing they understand the specific characteristics of a project and its sector? Their approach to assessments is as important. Are they thorough? Do they gather and incorporate technical and timeline requirements? Do they have the capacity to responsively adapt and provide additional services such as maintenance? Certifications and standards are crucial, as they define quality, safety, and performance. The most fundamental is ISO 8528 for generator sets. Also look for standards such as ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 3046 (combustion engine management). Others include adherence to health & safety, testing, and sector-specific standards (such as food safety considerations at a food & beverage advanced motor protection and energy- efficient lighting, play a defining role. Motor-driven systems remain among the largest consumers of electrical energy in any operation. Poorly controlled or unprotected motors not only increase energy waste but also pose risks from unplanned downtime and equipment failure. Modern MCCs address this challenge by centralising control, improving visibility and enabling smarter operation of motor systems. With integrated monitoring, automation compatibility and scalable design, MCCs allow businesses to optimise performance while reducing unnecessary energy consumption. Equally critical is the role of advanced motor protection. Electrical faults such as overloads, phase imbalance and voltage instability are not merely maintenance issues; they directly contribute to inefficiency and energy loss. Intelligent protection solutions detect and respond to these conditions early, preventing damage, extending equipment life and ensuring that systems operate within optimal parameters. In doing so, they protect both assets and energy investment, making protection a driver of efficiency rather than simply a safeguard. Lighting offers another major opportunity for immediate, measurable energy savings. The transition to LED technology has already transformed energy consumption profiles, but the real value lies in pairing
and clean power. A mine requires generators that operate underground in confined spaces while meeting safety, emission, and noise requirements. Meanwhile, a construction site’s generators need to be rugged, hold enough fuel for ongoing activities, and be transportable to support a range of different equipment as the site progresses. The challenge for each is to select the right generator solution. It is rare that a standard generator set can meet such specific requirements, which is where generator customisation comes in. This process requires coordinating specifications from several stakeholders, says Louis Kotze. “Selecting a generator set depends on factors that come from different people. The site’s electrical engineer focuses on areas like load requirements, total output and reliability, while procurement managers are interested in cost-related issues and emissions regulations, and project managers want to know that the generators will support their project goals and not become a hindrance. Each party knows what they expect from a generator. What they don’t have time for is to work out all the details.” Customisation needs the right partner The generator marketplace has a wide array of ratings and standards. A generator set can range from a straightforward off-the-

manufacturer). Focus on the team behind the customisation to ensure a site gets the right generator sets, says Kotze. “Engineers and managers on sites know what they want. What they need is someone who can connect the dots for them quickly yet professionally. Selecting and customising a generator solution requires skill. But what’s often neglected is understanding the customer’s goals and how customisation will achieve them. When deciding on a generator provider, that’s where the real value comes from.”

The result is a clean, unified assembly engineered to the specific demands of the application, with much of the complexity handled in a controlled factory environment rather than on a busy job site. Conclusion: a forward-looking approach The integration of VFDs and soft starters into standard MCC footprints is rapidly becoming the norm across industries seeking efficiency, reliability, and streamlined project delivery. While this approach introduces new technical challenges—particularly in thermal and harmonic management—the benefits for contractors and end-users are substantial. As factory-tested, plug-and-play MCC solutions become more sophisticated, the future of motor control is set to be smarter, safer, and more energy-efficient than ever. Proper integration is essential for facilities to obtain regional energy conservation certificates. Authorities now require detailed energy usage logs and validation that all asset monitoring is active and accurate before issuing compliance documents. Contractors must be prepared to provide comprehensive handover documentation, including: • As-built diagrams showing device placement and network connections • Device configuration files and communication settings • Sample energy and asset data screenshots or exports A new skillset for a new era As compliance requirements grow, so does the responsibility of electrical contractors. Staying ahead requires investment in training in smart relay programming, EMS integration, and data verification. By mastering these demands, contractors not only ensure smooth project delivery but also position themselves as vital partners in clients’ long-term energy efficiency and regulatory journeys. In summary, compliance-driven energy and asset tracking is here to stay. Forward- thinking contractors who embrace these requirements will lead the way in delivering safe, efficient, and future-ready electrical systems.
These measures ensure long-term reliability and compliance with stringent power-quality standards, even as the density of electronically controlled motors increases. Impact on contractors: complexity Moves to the factory floor The push to integrate VFDs and soft starters into MCCs fundamentally shifts the installation and commissioning process. Rather than mounting drives in loose field enclosures and performing complex on-site wiring, contractors can now specify factory-assembled MCC sections that are prewired, pretested, and ready for quick connection. This not only improves installation quality and reliability but also reduces on-site labour, commissioning time, and the risk of costly errors or rework. This trend also means that contractors must work closely with MCC on energy consumption, essential for energy audits and billing accuracy. • Reactive power (kVAR): Insights into system inefficiencies and opportunities for improving power factor. • Power factor: Key for maintaining grid stability and avoiding utility penalties. • Voltage imbalances: Early warnings for equipment stress or potential failures. These relays form the backbone of an integrated EMS, providing critical information to the building management system (BMS) or to cloud-based dashboards. Contractor impact: installation, integration, and documentation For contractors, the implications are significant. It’s no longer enough to simply install protective devices; contractors must ensure that smart overload relays and other monitoring components are properly networked and configured to communicate with the BMS or remote dashboards. This includes: • Correct wiring and commissioning of digital communication protocols (Modbus, BACnet, etc.) • Verification of data mapping to ensure that all required parameters are logged and easily accessible • Testing interoperability with the customer’s preferred EMS or BMS platform
regulatory reporting. As a result, electrical contractors are now on the front line of deploying and commissioning these systems. Smart overload relays: the new standard A critical component in this compliance- driven environment is the smart overload relay. Unlike traditional relays, modern devices also function as high-precision power meters. They do more than protect motors—they provide granular logging of: • Active power (kW): Real-time data
power control systems to incorporate integrated Energy Management Systems (EMS). This shift is more than a technical upgrade—it’s a fundamental change in how energy and asset data must be tracked, reported, and handed over. The code mandate: integrated EMS Modern regulations are clear: new and retrofitted facilities must incorporate EMS functionality into their power control architectures. This is not just about
Integrated VFDs and soft starters in standard footprints: transforming MCCs for modern demands A s the industrial landscape continues to evolve, the drive for greater energy efficiency Thermal and harmonic management: new engineering challenges
Packing advanced power electronics such as VFDs into standard MCC compartments poses significant engineering challenges, particularly in heat dissipation and harmonic mitigation. VFDs generate considerable heat during operation, and their compact integration in MCCs can quickly raise compartment temperatures beyond safe operating limits if not properly managed. Additionally, VFDs introduce harmonic distortion into the power system, which can lead to equipment malfunctions, overheating, nuisance tripping, and reduced power quality for other loads. To address these issues, contractors are now required to integrate built-in active harmonic filters and advanced cooling configurations directly into the MCC lineup. Solutions such as forced ventilation, high- performance heat sinks, or air-to-air heat exchangers are increasingly standard.
and tighter operational control is fundamentally reshaping electrical infrastructure across manufacturing, water treatment, and process industries. One of the most significant trends in this transformation is the integration of Variable Frequency Drives (VFDs) and soft starters directly into Motor Control Centres (MCCs) via standard footprints. This article examines the drivers of this shift, the challenges it poses, and the practical impacts on contractors and end- users alike. Industry drivers: energy efficiency and space optimisation Clients across multiple sectors are increasingly focused on reducing their energy footprints in response to rising utility costs and regulatory pressures. VFDs and soft starters provide precise control of motor speed and torque, delivering substantial energy savings, improved process control, and reduced mechanical stress. Traditionally, these devices were installed in separate wall-mounted enclosures—a solution that required additional space, complex wiring, and field commissioning. However, as facility footprints become more constrained and clients demand cleaner, more streamlined installations, there is a growing expectation that VFDs and soft starters be integrated directly into MCC lineups. Using standard MCC compartments allows electrical rooms to be designed more compactly, with equipment that is easier to maintain and expand.

Advanced fire protection for South Africa’s battery storage boom A s lithium-ion batteries become central to backup power and energy storage systems, innovative passive
address the unique risks posed by thermal runaway events in Li-ion batteries. “Li-ion battery fires behave very differently from conventional fires,” he says. Fire protection strategies need to evolve “They burn at extremely high temperatures, can reignite hours after being extinguished, and release toxic gases during combustion. As battery storage becomes central to South Africa’s energy future, fire protection strategies need to evolve accordingly.” In response to this growing challenge, advanced passive fire protection technologies developed in Germany are now entering the South African market through PyroBrand and ASP Fire. The technology uses engineered, non- combustible glass granules that surround battery modules or cells, creating an inert insulating barrier that suppresses flames, absorbs heat, and helps contain thermal
runaway before it escalates. Unlike active suppression systems that rely on external intervention, passive protection solutions function continuously and automatically, making them particularly suited to battery storage environments where early containment is critical. A major shift towards preventative risk mitigation “This technology represents a major shift towards preventative risk mitigation,” explains van Niekerk. “The goal is not simply to extinguish a fire after ignition, but to minimise the probability of catastrophic propagation within battery systems.” The material has been tested to international standards and demonstrates thermal stability at temperatures exceeding 1 000 °C. Independent South African testing has also shown a significant reduction of toxic vapours
generated during battery failure events, an important consideration for enclosed battery rooms, logistics facilities, and energy storage installations. The technology is additionally being incorporated into specialised transport and storage containers for damaged or defective batteries, supporting safer logistics across sectors such as mining, telecommunications, manufacturing, renewable energy, and electric mobility. “With South Africa’s dependence on backup and standby power continuing to grow, the safe deployment of battery technologies is becoming a critical infrastructure issue,” concludes van Niekerk. “The industry needs solutions that combine compliance, operational resilience, and environmental responsibility. Passive fire protection is becoming an essential part of that conversation.”
fire protection technologies are helping to mitigate the growing risks of thermal runaway events As South Africa accelerates its adoption of backup power systems, battery energy storage solutions (BESS), and renewable energy technologies, the fire risks associated with lithium-ion (Li-ion) batteries are becoming an increasingly urgent concern for the electrical sector. From residential solar installations and commercial UPS systems to large-scale energy storage facilities, Li-ion batteries are now integral to modern energy resilience strategies. However, these systems introduce complex fire hazards that conventional suppression technologies are often ill-equipped to manage. According to Michael van Niekerk, CEO of ASP Fire, the industry must adapt rapidly to

Gas-to-power hopes hinge on terminals, tenants and timing By: Chris Yelland, EE Business Intelligence S outhern Africa’s gas sector has made some progress, with parallel developments in South Africa’s planned LNG import infrastructure and Mozambique’s expanding offshore LNG export industry. At Richards Bay, Zululand Energy Terminal has strengthened the commercial case for South Africa’s first planned LNG import facility. Reuters reported in June that ExxonMobil had signed a preliminary agreement to supply LNG to the terminal, reinforcing Richards Bay’s role as a future entry point for imported gas. This followed Eskom’s Heads of Agreement with ZET, under which Eskom is positioned as a foundational customer for LNG import, storage and regasification infrastructure linked to its proposed 3000 MW gas-to-power programme. For South Africa, LNG could support flexible generation, reduce diesel dependence and provide feedstock for industrial users. But the risks remain equally clear. Imported LNG is exposed to global price volatility, foreign exchange movements, port and pipeline constraints, and the risk that expensive gas-to-power locks consumers into long-term costs just as renewables, storage and demand flexibility are becoming cheaper. Mozambique, meanwhile, is moving in the opposite direction: from gas resource holder to major LNG exporter. Mozambique Rovuma Venture, led by Eni, has issued an international call for expressions of interest in a third floating LNG unit in Area 4 of the Rovuma Basin. The proposed facility could produce up to six million tonnes a year, with the engineering, procurement, construction, installation and commissioning (EPCIC) scope covering these activities in water depths of about 2000 m. With Coral Sul and Coral Norte, the tender confirms the growing importance of offshore LNG in Mozambique’s fiscal and industrial strategy. Gas is back on the agenda – but its bankability will depend on price, security, infrastructure, environmental risk and credible offtake.
Kalfresh has secured WELTEC BIOPOWER, a leading international technology partner, to deliver its landmark bioenergy facility at Kalbar in South-East Queensland, aligning with one of the world’s most experienced and proven providers of anaerobic digestion technology. The Queensland-based vegetable business has signed an agreement with the German company to design and build the first stage of the bioenergy facility, which will anchor the new Scenic Rim Agricultural Industrial Precinct. The WELTEC equipment is due to arrive on site in late August, when construction of the first anaerobic digestion (AD) tank will commence. The partnership marks a significant milestone and will unlock the paddock-to-power potential of Kalfresh’s vertically integrated business, which will convert crop residues, processing offcuts and agricultural waste into several renewable by-products. One by-product, a nutrient- rich digestate, will be returned to farms as a biofertiliser, advancing Kalfresh’s long-term vision of circular agriculture. Kalfresh CEO Richard Gorman said WELTEC BIOPOWER will use its proven stainless-steel tank technology, which ensures durability, corrosion resistance and long operational life. “For us, it was critical to work with a partner that has a track record of delivering reliable, long-term infrastructure,” Mr Gorman said. “This is proven technology, and we’re building it to last. We have visited many operational bioenergy sites overseas, including those designed and built by WELTEC. They have a reputation for designing efficient, high-quality systems that perform consistently. “Kalfresh sent a group of Queensland farmers to Germany in April to visit WELTEC sites and see the AD technology first-hand.” WELTEC BIOPOWER was established in 2001 and has planned, delivered and constructed more than 450 specialised stainless-steel biogas plants in the US, Japan, Cyprus, the UK and across Europe. Dirk Krumdieck, CEO and Head of Sales at WELTEC BIOPOWER, says the agreement reflects the extensive preparatory work and technical planning undertaken by WELTEC and Kalfresh in recent years. „We are excited to be delivering a flagship bioenergy project in Australia that combines Kalfresh’s agricultural innovation with our proven European biogas engineering experience,” Mr Krumdieck said. The project will be delivered in three stages. The first stage involves the construction of a
large digester with a diameter of 31.48 metres and a height of 8.8 metres, along with a digestate storage tank, all supported by the newly implemented WELTEC Control system. It represents a new model for Australian agriculture, in which farming, food production and energy generation operate side by side in a closed-loop system. At full capacity, the facility could feature 14 digesters capable of producing enough energy to power up to 31,000 homes or fuel up to 98 million kilometres of truck and bus travel annually. “Recent international events have made it clear there’s a real and immediate need for national fuel and fertiliser security,” said Mr Gorman. “The introduction of a home-grown, dispatchable source of renewable natural gas into the energy mix comes at an important time. We can help transition Australia’s emitters towards emissions- free operation. “This is a practical, farmer-led solution that works today and can be replicated in the future in agricultural communities across the country, adding value to what is already produced on farms.” The Scenic Rim Agricultural Industrial Precinct will co-locate advanced food manufacturing on a 40-hectare site fronting the Cunningham Highway, approximately one hour from Brisbane. The Precinct will feature 16 serviced lots, three of which are occupied by Kalfresh, with access to on- site renewable power and circular waste services.
