Sustainable Cable Manufacturing: Our Commitment to the Environment
The cable industry, like many manufacturing sectors, faces increasing pressure to minimize its environmental impact. At Newtek Kabel, we believe that sustainable manufacturing isn't just an ethical choice—it's a business imperative. Through innovative processes, material selection, and energy management, we're reshaping the future of cable manufacturing to be greener and more sustainable.
Our Environmental Journey
Newtek Kabel's sustainability journey began over a decade ago with simple waste reduction initiatives. Today, we've transformed our entire operation with a comprehensive approach to environmental responsibility that encompasses every aspect of our business—from raw material sourcing to end-of-life product management.
In 2018, we formalized our commitment by establishing a dedicated Sustainability Team and developing a concrete roadmap with measurable targets. Our goal is ambitious but clear: to become the industry leader in sustainable cable manufacturing while maintaining the exceptional quality and reliability our customers expect.
Eco-Friendly Materials: Rethinking Cable Composition
Traditional cable manufacturing relies heavily on plastics derived from petroleum, metals from energy-intensive mining operations, and potentially hazardous chemical additives. Our material innovation strategy aims to replace these conventional inputs with more sustainable alternatives without compromising on performance.
Key Material Innovations
Recycled Copper and Aluminum
Up to 85% of our metal conductors now come from recycled sources, reducing the need for new mining while maintaining optimal electrical conductivity. Our advanced refining processes ensure that recycled metals meet the same stringent quality standards as virgin materials.
Bio-Based Insulation
We've pioneered the development of insulation materials derived from renewable resources like plant oils and starches. These bio-based alternatives have a carbon footprint up to 70% lower than conventional PVC while offering comparable or superior technical properties.
Halogen-Free Flame Retardants
All our cables now use advanced halogen-free flame retardant systems that minimize toxic emissions during fires while still providing the necessary safety protection. These environmentally friendly additives significantly reduce the potential for environmental contamination.
Reduced Chemical Additives
Our reformulated compounds use up to 30% fewer chemical additives than industry standards. We've eliminated phthalates, lead stabilizers, and other compounds of concern, making our cables safer both for the environment and human health.
Energy Efficiency and Carbon Reduction
Manufacturing operations, especially extrusion and metal drawing processes, are traditionally energy-intensive. We've implemented a multi-faceted approach to minimize our energy consumption and associated carbon emissions:
- Renewable Energy: Our facilities now derive 78% of their electricity from renewable sources, including our own rooftop solar installations and power purchase agreements for wind energy.
- Equipment Modernization: We've invested over €3 million in high-efficiency equipment that reduces energy consumption by up to 40% compared to older machinery.
- Heat Recovery Systems: Waste heat from extrusion processes is captured and reused for facility heating and preprocessing of raw materials, creating closed-loop energy systems.
- Process Optimization: Advanced monitoring and control systems minimize idle time and optimize production parameters for maximum energy efficiency.
The result of these initiatives is a 35% reduction in our carbon footprint per ton of cable produced since 2018, with a commitment to achieve carbon neutrality for our entire operation by 2030.
Water Conservation and Pollution Prevention
While cable manufacturing is not as water-intensive as some industries, we recognize the importance of preserving this precious resource and preventing water pollution:
Closed-Loop Cooling Systems
Our redesigned cooling systems have reduced water consumption by 85% through recirculation and advanced cooling tower technologies. The minimal makeup water required comes from harvested rainwater when possible.
Zero Liquid Discharge
We've implemented zero liquid discharge systems at our main manufacturing facilities, ensuring that no industrial wastewater leaves our premises. All process water is treated and reused internally.
Water-Based Alternatives
Where possible, we've replaced solvent-based processes with water-based alternatives, reducing both air emissions and the potential for hazardous waste generation.
Stormwater Management
Advanced stormwater management systems at all our facilities include bioswales, permeable paving, and retention basins that protect local watersheds and replenish groundwater.
Waste Reduction and Circular Economy
Our commitment to sustainability extends to comprehensive waste management, with a focus on creating circular economy solutions wherever possible:
- Near-Zero Manufacturing Waste: Through precise control of our manufacturing processes, we've reduced scrap rates to below 0.5%, well below industry averages of 3-5%.
- Internal Recycling: 100% of our internal plastic and metal scrap is recycled back into our production processes through specialized reprocessing technologies.
- Take-Back Programs: We offer customers the option to return end-of-life cables for responsible recycling, closing the loop on material use and preventing improper disposal.
- Packaging Innovations: Our packaging is now 95% recyclable or biodegradable, with a focus on reusable solutions like our award-winning returnable cable reels.
Product Design for Sustainability
True sustainability must be designed into the product from the beginning. Our eco-design principles include:
- Minimalist Design: Optimizing cable constructions to use the minimum material required while still meeting or exceeding performance specifications.
- Extended Lifespan: Designing cables with enhanced durability and aging resistance, extending service life and reducing replacement frequency.
- Ease of Recycling: Developing cable structures that can be more easily separated into constituent materials at end-of-life.
- Carbon Footprint Assessment: Evaluating the lifecycle carbon impact of new designs and prioritizing lower-impact alternatives.

Certifications and Transparent Reporting
We believe in holding ourselves accountable through rigorous third-party verification and transparent reporting of our environmental performance:
ISO 14001
Environmental Management System certification across all manufacturing sites
ISO 50001
Energy Management System certification for optimized energy efficiency
Carbon Trust Standard
Verified carbon footprint reduction achievements
Our annual Sustainability Report provides comprehensive disclosure of our environmental metrics, progress against targets, and ongoing initiatives. We follow Global Reporting Initiative (GRI) standards to ensure our reporting is consistent, complete, and comparable.
The Path Forward: Our Sustainability Roadmap
While proud of our progress, we recognize that sustainability is a journey, not a destination. Our roadmap for the coming years includes:
- Carbon Neutrality by 2030: Eliminating or offsetting all direct and indirect emissions from our operations and purchased energy.
- 100% Sustainable Materials by 2035: Transitioning to exclusively recycled, renewable, or bio-based inputs across our entire product range.
- Zero Waste to Landfill by 2025: Eliminating all landfill waste through enhanced recycling, reuse, and responsible treatment.
- Supply Chain Engagement: Extending our sustainability principles throughout our supply chain through education, incentives, and requirements.
- Product Carbon Labeling: Providing transparent carbon footprint information for all products to help customers make informed choices.
