Sustainable Production: Reducing Environmental Impact in Industry
The industrial sector stands at a turning point. As pressure mounts to limit environmental harm, companies across manufacturing, automotive, materials, and energy are being asked to do more than comply with regulation , they are being asked to lead. The Kestria Industrial/Production Global Practice Group recently brought together six senior industry leaders from different regions and sectors to discuss how their organisations are reducing environmental impact, managing energy transitions, and building sustainability into the core of their business strategy.
Their conversation offers a grounded, practical picture of what sustainable production actually looks like today: incremental, technical, often constrained by cost and infrastructure, but moving steadily in one direction.
Three Themes Emerge
Across every industry represented cement, automotive components, composites, wood products, and consumer manufacturing three consistent themes stood out.
First, energy resilience is now a driver of innovation, not just a cost-saving measure. Companies are investing in solar power, waste heat recovery, and modular renewable systems to keep operations stable, particularly in regions with unreliable electricity grids.
Second, true circularity remains difficult to achieve. Recycling progress is real, especially for materials like PET plastic and lead, but full closed-loop systems are still limited by economics and a lack of supporting infrastructure.
Third, sustainability has moved into the boardroom. It is increasingly treated as a strategic performance indicator, with leadership teams aligning supply chains, operations, and staff incentives around long-term environmental goals rather than short-term compliance.
Cutting Waste and Rethinking Materials
In the cement industry, which accounts for roughly 8% of global CO₂ emissions, the approach is less about reducing waste and more about using it productively. Rather than sending waste to landfill, cement producers are burning alternative fuels such as used tyres in place of fossil fuels, with some manufacturers targeting fuel substitution rates as high as 50%. Producers are also cutting the use of clinker, the most carbon intensive ingredient in cement, by blending in materials such as sugar cane ash, a technique with roots stretching back to Roman construction.
In the automotive sector, the shift toward hybrid and hydrogen vehicles is being accelerated by tightening emissions regulation in Europe, including an eventual ban on new internal combustion engine vehicles. Component manufacturers exporting into these markets are adapting lean manufacturing practices and running closed-loop recycling systems for materials like lead, which despite being energy-intensive to produce, is almost fully recyclable through battery return programmes.
For composite materials manufacturers supplying the wind energy industry, the challenge is more structural. Recycled PET plastic is used to make foam cores for turbine blades, but once that foam is bonded with resin, separating the materials at end of life becomes extremely difficult and costly. Many blades therefore still end up in landfill after their 20-to-25-year service life. The same foam technology is proving more circular when used in office furniture, where it replaces heavier wood cores, though even here, long product lifespans of 10 to 20 years slow down material recovery.
Wood products manufacturers have found one of the more complete circular solutions: recovering fibre from demolished buildings and old furniture, reusing the longer fibres in new panel products
The central conclusion drawn from this framework is that executive search is evolving away from process execution and toward strategic interpretation, contextual assessment, and trust brokerage. The value proposition has shifted from identifying candidates to determining which candidate is appropriate, explaining cultural fit, and articulating leadership trade-offs and risks.
Powering the Transition
Energy transition strategies vary sharply by region, shaped largely by grid reliability and available government support.
In South Africa, years of power shortages between 2022 and 2024 pushed industry toward one of the fastest national shifts to solar power seen globally, with nearly nine gigawatts of new capacity added in 2024 alone, more than five gigawatts of it from rooftop installations. For manufacturers operating there, solar has become both a resilience measure and a straightforward financial decision, offering fast returns even for cautious organisations.
In Europe, government and EU subsidies are helping industrial sites cover a substantial share of their electricity needs through solar power, illustrating how policy support can accelerate adoption in ways that self-funded projects alone cannot.
Cement producers are pairing renewable energy investment with technical efficiency gains including lower energy grinding equipment and waste heat recovery systems that capture heat from kiln stacks and convert it into usable power, in some cases offsetting up to 30% of total site energy demand. Some producers are even applying machine learning to production processes, reducing variation and, in turn, energy consumption.
Extending Sustainability Through the Supply Chain
For manufacturers whose own operations produce relatively little direct emissions, the real sustainability challenge lies upstream. Composite materials producers, for instance, report that more than 95% of their carbon footprint comes from raw material suppliers rather than their own facilities. Meeting emissions targets in these cases depends less on renewable energy at a single site and more on close collaboration with suppliers particularly where a large share of the supply chain runs through markets where recycled materials remain more expensive than virgin alternatives.
Responsible sourcing certification plays a similar role in wood products manufacturing, where companies work to source only from forests where growth outpaces harvesting, and where separate certifications govern chemical emissions, biodiversity impact, and indoor air quality standards for finished products.
Consumer goods manufacturers operating across multiple regions describe a mix of approaches suited to local conditions: combined heat and power systems and solar installations in South Africa, a shift to compressed air and nitrogen-based propellants in aerosol products globally, and reflective roof coatings in high-temperature climates like Bahrain that have cut site energy consumption by close to 5%. A common thread across these examples is treating suppliers as long-term partners rather than transactional vendors, with open sharing of best practices around energy, water, and emissions.
Leadership Makes the Difference
Perhaps the clearest message from the discussion is that technology alone does not drive sustainable production leadership.
Executives point out that sustainability has evolved considerably since the first Rio climate summit in 1992, moving from a peripheral concern to a core measure of business performance, backed by data and reviewed at the highest levels of leadership. Companies increasingly use structured measurement systems, often built around a fixed baseline year, to track resource use and emissions over time, even as their operations expand. Several organisations now link sustainability performance directly to compensation, treating it as a genuine strategic priority rather than a reporting exercise.
At the same time, leaders acknowledge that regulation has not always kept pace intelligently with the transition with some describing certain European sustainability regulations as overly burdensome for smaller companies, even as they welcome recent efforts to simplify these frameworks.
Conclusion
What emerges from these conversations is not a single formula for sustainable production, but a shared direction of travel: reduce waste by using it rather than discarding it, pursue circularity even where it remains only partially achievable, invest in energy resilience suited to local conditions, and extend responsibility beyond the factory gate to suppliers and partners.
Progress is uneven across regions and industries, shaped by infrastructure, cost, and regulatory maturity. But as sustainability becomes embedded in corporate strategy and leadership accountability, the industrial sector is steadily building the practices and the leadership talent needed to balance growth with environmental responsibility.
