Innovative Methods and Key Metrics in Sustainable manufacturing:
Moving from ideation to action

In today’s world, sustainability isn’t just a buzzword; it’s an absolute necessity. So, how can top electronics manufacturers serving diverse global clients in industries like consumer tech, automotive, health, and beauty stay ahead of the curve? By embracing sustainable production methods and robust metrics that create accountability for your sustainable efforts.

Through this blog, we pin down our research of innovative sustainable production practices and the essential metrics used to measure their effectiveness. Explore how these strategies not only enhance environmental stewardship but also boost your relevance and appeal to prospects and clients.

Embracing Sustainable Production Methods

Sustainable business involves creating products through economically sound processes that minimise negative environmental impacts while reducing use of energy and natural resources. Here are some key methods:

1. Lean Manufacturing

Lean manufacturing is a systematic approach aimed at minimising waste and maximising value within a manufacturing sector. Originating from Toyota’s production system, lean principles focus on value creation for the customer using fewer resources by optimizing workflows and eliminating non-value-added activities.

This approach employs tools like 5S (Sort, Set in order, Shine, Standardize, Sustain), Kaizen (continuous improvement), and Just-In-Time production to enhance efficiency, reduce costs, and improve overall quality. In the electronics manufacturing industry, lean manufacturing is particularly impactful as it addresses common challenges such as high-mix, low-volume production, rapid technological advancements, and the need for precise quality control.

2. Additive Manufacturing

Also known as 3D printing, additive manufacturing creates objects by layering materials. This technique is highly resource efficient as it minimizes waste, with unused materials often being recyclable. According to research, additive manufacturing can reduce material waste by up to 90% compared to traditional methods, thus promoting green manufacturing.

3. Renewable Energy Integration

Incorporating renewable energy sources such as solar, wind, and bioenergy into manufacturing processes reduces reliance on fossil fuels and lowers greenhouse gas emissions.

Apple has expanded renewable energy across its global supply chain to 13.7 gigawatts, avoiding 17.4 million metric tons of carbon emissions in 2022 alone. This is equivalent to removing nearly 3.8 million cars from the road. (Source)

4. Material Substitutes

Traditional PCBs are often made from materials like fiberglass and epoxy resins, which are not only resource-intensive to produce but also challenging to recycle. Their disposal leads to pollution of various natural habitats. However, advancements in materials science are paving the way for greener alternatives. Biodegradable substrates made from natural fibers and resins are being developed, reducing the environmental impact during both production and disposal.

Additionally, using conductive inks and adhesives derived from renewable sources can further lessen the ecological footprint of electronic devices. Companies like Samsung are actively incorporating these sustainable materials into their manufacturing practices, aiming to reduce the overall environmental impact and improve recycling rates.

Key Production Metrics for Sustainable Production

Sustainability is a topic of high value today. Companies are rolling out their sustainability reports, publishing their green efforts and taking steps to include sustainable manufacturing practices as a part of their business proposals. But how do we identify that the efforts are bringing the desired output. This is where metrics help us draw the growth graph that is purposed to lead us to a greener, more efficient tech-economy:

• Carbon Footprint:
  This metric measures the total greenhouse gas emissions produced by manufacturing processes. Reducing the carbon footprint is a primary goal for sustainable production, often achieved through energy efficiency and the use of renewable energy sources.
• Energy Consumption:
  Tracking energy use helps identify opportunities for efficiency improvements. Lower energy consumption not only reduces costs but also minimizes environmental impact.
• Water Usage:
  Monitoring water usage is critical, especially in regions where water is scarce. Implementing water-saving technologies and recycling water within manufacturing processes can significantly reduce water consumption.
• Waste Reduction:
  Measuring the amount of waste generated and recycled is crucial. This includes tracking solid waste, hazardous waste, and by-products. The goal is to achieve zero waste through recycling and reuse. For example, one jeans factory called Site reduced the water used to make each pair of jeans from 800 litres to less than 1 litre by employing lean principles. This initiative was a part of Everlane’s broader commitment to sustainability and reducing the environmental impact of denim production (Source)
• Resource Efficiency:
  This metric evaluates how effectively materials are used in the production process. High resource efficiency means more products are created with fewer raw materials, reducing waste and costs.
• Lifecycle Assessment (LCA):
  LCA evaluates the environmental impact of a product throughout its lifecycle, from raw material extraction to disposal. This comprehensive metric helps manufacturers understand and mitigate their environmental impact at every stage.
• Sustainable Sourcing:
  Tracking the percentage of materials sourced sustainably ensures that raw materials are obtained in an environmentally and socially responsible manner.
• Employee Health and Safety:
  Ensuring a safe and healthy work environment is part of sustainable production. Metrics include accident rates, sick days, and employee well-being programs.
• Product Longevity and End-of-Life Management:
  Measuring the durability of products and their recyclability at the end of their lifecycle is crucial. This metric ensures that products are designed for longevity and easy recycling, supporting circular economy principles.
• Customer Satisfaction and Eco-Labels:
  Tracking customer feedback and certifications related to sustainability, such as Energy Star or EPEAT, can provide insights into how sustainable practices are perceived and valued by customers.

Real-World Applications and Benefits

Adopting sustainable production methods and tracking relevant metrics benefits manufacturer networks in numerous ways. Here are a few of those many examples:

• Cost Savings: Efficient use of resources and energy reduces operational costs.
• Brand Reputation: Demonstrating a commitment to sustainability enhances brand image and can attract environmentally conscious customers.
• Regulatory Compliance: Adhering to environmental regulations avoids penalties and promotes business continuity.
• Market Differentiation: Offering sustainable products can differentiate a company in a competitive market.
• Long-Term Viability: Sustainable practices ensure the long-term availability of resources and the health of ecosystems.

For instance,

• Apple’s integration of renewable energy and commitment to carbon neutrality by 2030 showcases its leadership in sustainable production.
• Samsung’s expanded use of recycled materials and collaboration with global initiatives further highlights its dedication to sustainability.
• According to research from the University of Cambridge, implementing rapid sustainability improvements can result in up to 15% efficiency gains, proving that small, iterative changes can lead to significant benefits.

Commitment to sustainable production is essential for the future of our planet and the success of businesses. By embracing advanced manufacturing technologies and tracking comprehensive production metrics, companies can achieve remarkable efficiency, reduce their environmental impact, and meet the growing demand for sustainable products. As the industry evolves, staying ahead of these trends will not only benefit the environment but also enhance competitiveness and customer loyalty.

The next step for manufacturers is clear.  Make sustainable production a part of your production lifecycle and lead the way to a greener, more sustainable future.
