Sustainability in Manufacturing Processes

My Co-Founder, CTO, and brother David Lu made a point in his TEDxHarvardSquare talk that I keep coming back to: for technology to create lasting change in process manufacturing, sustainability has to mean three things simultaneously – people, environment, and operations. Pull one out and the whole thing falls apart. Most sustainability conversations in this industry treat environmental impact and operational performance as separate goals – one for the ESG report, one for the P&L. The reality on the factory floor is that water saved is cost saved, chemicals reclaimed are margin recovered, and energy optimized is productivity gained. Every single cycle Laminar runs makes the production line more sustainable and more efficient at the same time, because the two outcomes are driven by the same underlying decision: act on real-time data instead of a static timer set decades ago. People means the operator on the floor has to understand what the technology is recommending and why. Decades of institutional knowledge can't be bulldozed by an algorithm that nobody can explain – the technology has to earn trust by being explainable, accessible, and built for the person standing at the line, not the analyst sitting at a dashboard. Environment means every cleaning cycle, every chemical dose, every gallon of water has to be genuinely optimized rather than performatively reported. Operations means the savings have to show up on the balance sheet in a way that makes the decision to keep running Process-Aware Autonomy an obvious one. When all three work together, sustainability stops being a cost center and starts being a compounding advantage. Laminar is built on exactly that thesis of productivity and sustainability being the same decision that ultimately creates value for the facility.

Most "green" manufacturing initiatives fail. Why? They focus on looking good instead of being good. Here's our real playbook: 1. Energy First: • Switch to smart LED systems • Install motion sensors • Monitor machine idle times Small changes = Big savings 2. Waste Revolution: • Measure your waste by TYPE • Reprocess clean room garments • Partner with recycling specialists Cut waste = Cut costs 3. Package Smart: • Eliminate plastic where possible • Use recycled sterilization wraps • Design collapsible packaging Less space = More profit 4. Water Control: • Install closed-loop cooling • Reuse validated water • Monitor usage by process Every drop counts 5. Supply Chain Reality: • Source locally where possible • Bulk ship raw materials • Choose suppliers by carbon footprint Proximity = Profitability 6. Clean Room Efficiency: • Use HEPA instead of complete air changes • Install energy recovery systems • Monitor particle counts real-time Better control = Less waste The truth about sustainable manufacturing? It's not about being green. It's about being efficient. Efficiency equals sustainability. Start here: Measure your waste for one week. Track everything. The numbers will shock you. #MedTech #SustainableManufacturing #CleanTech

Sustainability in Pharmaceutical Industry 26% of Emcure’s revenue comes from injectables but did you know that syringes are one of the toughest to recycle ? Around 16 billion syringes are used annually around the world and they are typically disposed of by incineration or end up in landfills. Most recycling firms are unwilling to accept syringes due to the potential dangers of needle sticks and contamination with pathogens and biological fluids. As you can see from this one example, pharma industry truly has its unique set of environment related challenges. Below I have tried to summarize a few industry specific sustainability issues. Manufacturing . Using Safer solvents (eg Pfizer’s switch to using ethanol and water instead of methylene chloride in the synthesis of Viagra reduced hazardous waste by over 95%), Using Better Catalysts (eg Merck’s use of an enzymatic process in the diabetes drug Januvia reduced waste by 56%), implementing advanced process control and automation (eg Precise temperature and pressure control in reactors helped Astra Zeneca reduce energy consumption by 20%). Finally by recovering and reusing waste heat, overall energy demand can be significantly reduced. Eli Lilly saved an estimated 8000 MWh of energy annually. R&D - Use of digital twins, which are virtual copies of physical assets that provide insights into the performance of their real-world counterparts reduces the use of material and energy consumption. Delivery Mechanisms: E.g. in inhalers, the evolution of propellants from Chloroflurocarbons (damage ozone layers) to dry-powder inhalers has cut carbon emissions by 95%. Packaging: Companies have started recycling, re-using material, and ensuring proper disposal of plastics. Astellas used biomass based plastic from sugarcane for their blister packages. Adoption of QR codes on packaging reduces the need for physical pamphlets. Cold-chain: Keeping products at 2-8 degrees uses a lot of energy and plastic packaging. Optimization of route and improvement in packaging are being worked on. Sourcing: Most companies are now evaluating vendor partners on sustainability criterions. However the sad reality is that most API is sourced from India and China where environment issues are rampant. The documentary “ An unequal fight” on the severe impact of industrial pollution in Patancheru is a shocking tale. Waste management: The Environment Protection Rules 1986 requires installation of Effluent Treatment Plant (ETP) to treat waste generated before it is disposed off. Emcure uses ETP and has invested in renewable energy. At a corporate level, better lighting, less paper, such policies are implemented across the board. Emcure is also using modulation of its Cooling Tower Pump at Kurkumbh (precision heat and pressure) to reduce energy consumption. Bottomline - While pharma companies are working on sustainability measures, the reality is that this space remains challenging and we have only scratched the surface !

The manufacturing landscape is evolving rapidly, driven by AI, sustainability, and agility. My experience at RSWM Limited has shown that progress stems from blending technology with human insight. Beyond automation, success lies in intelligent collaboration. Agentic AI predicts maintenance, optimises supply chains, and boosts efficiency. Value emerges when teams innovate with these systems. Our shift to biofuels and zero-liquid-discharge operations illustrates how discipline transforms waste into value and enhances profitability. Sustainability is core to strategy. Circular models, recycled materials, and bio-fabrication set new standards. GreenStitch’s AI platform supports this by centralising data, automating ESG reporting, and tracking carbon footprints for informed decisions. Agility is vital amid trade shifts and climate disruptions. Market diversification and digital adoption foster resilience: the strength Indian manufacturing has shown across cycles. The future of manufacturing depends on intelligence, agility, and purpose. AI-enabled factories and digital supply chains are becoming standard practice while sustainability is embedded in operations rather than positioned as a CSR initiative. Leadership excels via effective technology integration: data-driven decisions, balanced profitability, responsive systems, and skilled teams. Concerns about AI replacing jobs ignore historical trends. Technology has always redefined roles rather than eliminated work. Supply chains are now AI-driven, equipment uses smart sensors, automated changeovers are standard, and predictive insights have replaced manual inspection. Customer engagement has moved from physical catalogues to digital portfolios, meeting global regulatory and market standards. Today’s manufacturing leaders must ask sharper questions, take informed risks, and build organisations that evolve continuously. Future factories will rely on engineering excellence, strategic clarity, and strong cultural alignment. #manufacturing #AI #agenticAI #technology #leadership #leadwithrajeev

What’s one thing that can turn a good sustainability plan into a great one? As we work to make businesses more sustainable, there’s one approach that often flies under the radar but makes a real difference: Six Sigma. Yes, the same Six Sigma that transformed manufacturing can also be a powerful tool in sustainability efforts. Here’s how. Six Sigma starts with a focus on the customer—whether that’s a buyer or the environment. It’s a way of reducing waste, spotting inefficiencies, and refining processes to reduce errors. In sustainability, accuracy matters more than ever. Six Sigma helps teams pinpoint where waste occurs, how much, and what impact it has, using data to make decisions with confidence. To break it down, Six Sigma follows five steps, each with a purpose: -Define – This is where the team starts by identifying the problem clearly. Imagine a project aiming to cut down on packaging waste. Define the specific waste issues, what success would look like, and who the key “customers” of this improvement are—whether it’s the planet, a community, or the bottom line. -Measure – Next, collect data. For instance, if packaging waste is the focus, measure how much waste is currently generated. Analyzing the flow of materials allows for precise benchmarks that ensure improvements are tracked effectively. -Analyze – This is where teams dig deep, examining the causes of waste or inefficiencies. In our packaging example, they might find that excessive or non-recyclable materials are the primary issues, pinpointing areas to change. -Improve – Now, with root causes in hand, it’s time to make changes. Teams might test out solutions like biodegradable materials or redesigning packaging to use less. Improvements are guided by data, making the process both strategic and impactful. -Control – Finally, sustaining progress means implementing control systems. Regular checks make sure that the new packaging methods continue to reduce waste and meet environmental goals. The result? Real, data-backed progress. Studies show that Six Sigma projects can reduce errors and waste by up to 50% while increasing productivity. For sustainability, that means cutting resource use, lowering emissions, and hitting those ambitious goals. Have you used Six Sigma in your work? Or Are you considering it for sustainability efforts?

Great illustration of the significance of material choice in product success. A palm leaf plate may look simple, but the outcome depends on a delicate balance of many factors. Too brittle, and it could break. Too moist, and it might deform. What looks like a straightforward forming process is more intricate and highly dependent on a number of things including physical properties. That is especially true with biomaterials. As more companies move toward sustainable alternatives, the challenge is beyond just about finding something biodegradable or renewable that can actually do the job. Can it handle heat and pressure? Will it hold form? Can it be sourced reliably? Will it behave consistently enough for commercial production? Is it cost effective? Can it be supplied in volumes? These questions are the core of every material selection decision for a product designer. A single choice can change manufacturing yield, product quality, shelf life, economics, and the amount of waste generated along the way. Which is why this work is part science, part engineering, part economics and part pattern recognition. That is also why this problem space is so fascinating to us at XTRIUM. The real magic is in understanding fit. 1. Material choice shapes process more than process shapes material. 2. Sustainability still has to pass the test of performance, manufacturability, cost, sourcing and repeatability. 3. Better decisions upstream save time, cost, and waste downstream. 4. Natural does not automatically mean manufacturable. 5. Material properties ripple across the entire product and process. 6. The smartest decisions are grounded in data, not just gut feel and hope. 7. Better material intelligence can save months of trial and error. 💫Dr. Sirisha K. Raghunandan Mathur Rekha Muralidharr Lisa Morales-Hellebo Brian Laung Aoaeh, CFA Vidhya Subramanian Andrew Eil

Overview of Green and Sustainable Manufacturing Processes: • Green and sustainable manufacturing focuses on creating products through processes that minimize environmental impacts, conserve energy and natural resources, and ensure safety for employees, communities, and consumers. The goal is to balance economic growth with environmental stewardship and social responsibility. • The 12 principles of green chemistry provide a framework for designing new chemical processes responsibly, reducing environmental footprints, and improving the safety of processes and products. • The American Chemical Society Green Chemistry Institute’s Pharmaceutical Roundtable has identified process mass intensity (PMI) as a key metric for evaluating and benchmarking sustainability efforts, moving beyond traditional metrics like E-factor and atom economy. • PMI is a key green chemistry metric. It tells you how much total material you use (including solvents, reagents, etc.) to make a unit mass of product. PMI = Total mass input (kg) / Mass of product (kg). • The aspirational goal for a green and sustainable manufacturing route is achieving a "zero-waste" process. • Hong Ren, Kevin Maloney, and colleagues demonstrated a green and sustainable manufacturing process for Gefapixant Citrate (MK-7264), achieving a low PMI, short synthetic sequence, high overall yield, minimal environmental impact, and significantly reduced API costs.   Limitations of Supply Process for Gefapixant Citrate 1:  • The process did not meet key success criteria for commercial manufacturing, including lead time, cost, process mass intensity (PMI), and robustness. • It involves a longest linear sequence of 11 steps, a high PMI of 366, a low overall yield of 16%, and a high API cost. • Several reactions in the route are unsuitable for commercial manufacturing due to the use of hazardous reagents and unsafe conditions. Advantages of green and sustainable commercial process for Gefapixant Citrate 1: • Reduced the process from 11 steps to 6 steps. • Achieved a significantly improved overall PMI of 78. • Increased overall yield from 16% to 60%. • Developed a more practical and cost-effective manufacturing route. • Replaced hazardous alkylation and two highly toxic chemicals, making the process safer and more robust. • Successfully demonstrated at >300 kg scale for the production of Gefapixant Citrate (1).

𝗠𝗼𝘀𝘁 𝗺𝗮𝗻𝘂𝗳𝗮𝗰𝘁𝘂𝗿𝗲𝗿𝘀 𝗱𝗼𝗻’𝘁 𝗵𝗮𝘃𝗲 𝗮 𝗰𝗮𝗿𝗯𝗼𝗻 𝗽𝗿𝗼𝗯𝗹𝗲𝗺 — 𝘁𝗵𝗲𝘆 𝗵𝗮𝘃𝗲 𝗮 𝗱𝗲𝗰𝗶𝘀𝗶𝗼𝗻 𝗽𝗿𝗼𝗯𝗹𝗲𝗺. And the real shock? The biggest drivers of carbon impact aren’t on the shop floor. They’re buried inside the operational choices we treat as routine. Sustainability in manufacturing isn’t achieved through big initiatives or glossy net-zero roadmaps. It’s shaped in the upstream decisions that determine how a factory behaves long before production begins. 𝗧𝗵𝗲 𝗿𝗲𝗮𝗹 𝗰𝗮𝗿𝗯𝗼𝗻 𝗱𝗿𝗶𝘃𝗲𝗿𝘀 𝗵𝗶𝗱𝗲 𝗶𝗻𝘀𝗶𝗱𝗲 𝗱𝗲𝗰𝗶𝘀𝗶𝗼𝗻𝘀 𝗹𝗶𝗸𝗲: → The point at which customisation is triggered → The logic behind batch formation and release → The routes materials take across the factory network → The timing and scope of equipment reconfiguration → The choice between additive, subtractive, or conventional processes Individually, these decisions look harmless. Collectively, they lock in the carbon signature of the entire system. 𝗛𝗲𝗿𝗲’𝘀 𝘁𝗵𝗲 𝗶𝗻𝗱𝘂𝘀𝘁𝗿𝘆’𝘀 𝗯𝗹𝗶𝗻𝗱 𝘀𝗽𝗼𝘁: You cannot reduce what you cannot see — and most organisations have zero visibility into the carbon ripple effects of these decisions. 𝗧𝗵𝗮𝘁’𝘀 𝘄𝗵𝗲𝗿𝗲 𝗗𝗶𝗴𝗶𝘁𝗮𝗹 𝗧𝘄𝗶𝗻𝘀 𝗯𝗲𝗰𝗼𝗺𝗲 𝘁𝗿𝗮𝗻𝘀𝗳𝗼𝗿𝗺𝗮𝘁𝗶𝘃𝗲. Not because they mirror the factory, but because they expose the hidden interactions, trade-offs, and consequences traditional tools never reveal. When organizations treat sustainability as an optimization variable and not a compliance box — everything shifts. Agility increases. Emissions fall. And decision intelligence becomes a true competitive advantage. Where are you seeing hidden decision friction in your operations , the kind that silently undermines sustainability? #DigitalTwin #SustainableManufacturing #Industry40

But once a fibre enters a dyehouse, chemistry and process conditions often determine the majority of the environmental footprint. Dye selection, auxiliaries, reduction chemistry, fixation efficiency, rinsing stages, wastewater treatment load. These are the factors that decide water consumption, energy demand and chemical discharge. Two fabrics made from the same fibre can leave the mill with completely different environmental profiles depending on the wet processing route used. The industry still talks about sustainability as if fibres alone determine impact. In reality the wet processing stage is where many of the largest variables appear.
