How Amazon learned to cut its cardboard waste
David Gasperino, an Amazon principal research scientist, led the technical development of PackOpt, which is helping Amazon’s stakeholders to not only minimize the amount of “air” shipped to customers, but also helping Amazon deliver on its Climate Pledge commitment to reaching net-zero carbon emissions across its business by 2040.
“To create an optimal set of boxes, you need to select a small subset of columns to pack all of the shipments, and those columns must lead to the smallest overall box volume when you sum it all up,” explains Gasperino. It is a hard challenge — literally. “This problem belongs to a theoretical class of problems called ‘NP hard’
The 100% Recyclable Running Shoe That’s Only Available by Subscription
To make a shoe that can be ground up, melted down and reincarnated as another shoe, Swiss sportswear brand On didn’t just need new materials and manufacturing processes. It designed a new sales model. In June, On began shipping the first 10,000 pairs of its latest model, starting with U.S. customers. The Cloudneo is pitched as “the shoe you will never own.” Instead, runners pay $29.99 a month for an endless supply, provided they return worn-out pairs to be recycled. On executives say this arrangement will lock in a supply of raw material for new shoes, reducing waste.

Researchers Consider the Circular Economy in Pulp and Paper Industries
The paper and pulp industries can benefit greatly from a cyclical model of manufacture. These industries are responsible for the consumption of most of the lignocellulosic biomass produced in the world. In 2020, the European paper and pulp industries alone consumed an estimated 146.5 million cubic meters of wood. The transition to a green economy approach is a chief concern in these industries.
Sensible CO2 recycling
Carbon dioxide from technical processes should no longer impact the climate. That is why a key objective of the voestalpine decarbonization strategy is to avoid its generation. But as long as carbon remains an indispensable component, for example in the production of high-quality steels, researchers are also looking into solutions to prevent or recycle CO2 emissions. In cooperation with a team from the K1-MET metallurgical research competence center, voestalpine is tackling this challenge.
Can AI help create less carbon-intensive concrete?
Cement is a popular binding and fortifying agent with a high production cost (and we’re not talking about $$): For every ton of cement produced, at least one ton of CO2 is released into the atmosphere—adding up to at least 8% of annual global emissions. The researchers trained a generative AI model on environmental impact data and a small public dataset. Using semi-supervised learning, the model sought out concrete formulas that checked all of the researchers’ boxes: 1) lower carbon footprint, 2) significant compressive strength, and 3) similar durability and other qualities.
Towards a more circular production in Scania Oskarshamn
Great achievements towards a more circular production are made at Scania’s cab factory In Oskarshamn, Sweden, since 2019. The production is fossil free since 2020, more material is recycled, and the energy consumption has decreased with several thousand MWh.
The beverage sector moving towards sustainable factories

Nissan Intelligent Factory enables Nissan to: Use robots that have inherited the skills of takumi to manufacture next-generation vehicles; of the highest quality, Create an improved environment where a wide range of people can work comfortably, and; Realize a zero-emission production system, thereby accelerating efforts to achieve a decarbonized society.
A new perspective on the mining industry
Certain geologies and structures ultimately have different vulnerabilities. Entering known data into a simulated environment or kind of digital twin, can help figure out the unknowns, assisting miners to decide where and how to apply their efforts. This is essential for remotely managed or autonomous vehicles that can achieve low waste, and efficient extractions in harsh or dangerous locations. Autonomous vehicles can actually extend operation hours, increasing productivity as well as reducing the use of energy hungry and personnel centred equipment. In an IoT network these may increasingly incorporate ‘intelligent’ or ‘smart’ devices that not only store or transmit but process data – as in a ‘smart factory’. “We’re seeing opportunities with sustainability oriented projects in Canada and Europe,” Sym-Smith says.
Minexx’s software platform uses blockchain digital distributed ledger, payments, biometric and IoT technologies to create much-needed trust and transparency around quality and methods of production. This helps clients manage aspects of know your customer (KYC) and anti-money laundering regulations as well, giving them and the artisanal miners access to markets and better prices. “Once data is on the blockchain, you can’t change it. Then essentially you give the manufacturer the key,” Scaramanga says.
The business of sustainability in steelmaking
These upgrades at the Train 2 plant allowed ArcelorMittal to save 15-20% on installation, reduce downtime by 5-10%, save 170 equivalent metric tons of CO2, and prevent reprocessing 26 tons of materials. Sensor-based equipment condition monitoring also let the steelmaker’s staff track energy use and identify potential faults before they cause downtime. These improvements also increase the facility’s installation reliability, energy efficiency, personnel safety and equipment life with predictive maintenance.
Make Digital Twins an Integral Part of Your Sustainability Program
Digital solutions provide the visibility, analysis and insight needed to address the challenges inherent in sustainability goals. A digital twin strategy as part of an overall digitalization plan can be a crucial capability for asset intensive industries such as refining and chemicals. A digital twin needs to encompass the entire asset lifecycle and value chain from design and operations through maintenance and strategic business planning.
Comprehensive sustainability solutions are stretching the capabilities of thermodynamic first principle-based digital twins and driving the need for the next generation of solutions. Reduced order hybrid models offer a critical capability to achieve digitalization, sustainability and business goals faster. Reduced-order models can abstract models to enterprise views which inform executive awareness and strategic decision-making. Site-wide models can run faster and more intuitively to drive agile decision-making and optimize assets to achieve safety, sustainability and profit.
Design for Sustainability
Typically, product designers select a few focuses, for instance, design for manufacturing (DFM), design for assembly (DFA) and design for reliability (DFR), and optimise those aspects of the product. Every design decision is evaluated in the light of the selected focus or focuses and relevant changes are then made taking the full life cycle of the product into account.
A sustainable alternative to this system is the circular economy. The main focus of this type of economic model is to reintroduce used parts as raw materials for new products. The intent is to move from a high-waste to a high-value model. Such a system is highly resource-efficient and reduces the effect of consumer demand on the exploration, pollution, and wastage of natural resources. Models such as biomimicry, cradle-to-cradle, product service systems (PSS), 4Rs, are all strategies that can provide design features to achieve a circular economy.
How 3D printing improves sustainability across the supply chain
After analyzing several studies about energy efficiency of 3D printing, the answer is not as simple. Due to very individual use cases (machine, product and process characteristics), comparability of traditional methods and 3D printing is not always generally possible. While compared with subtractive methods, 3D printing can be more energy efficient (especially due to lesser material consumption). The energy consumption of 3D printing compared to injection molding is generally considered to be higher due to a way longer production time per part (less than a minute per part for injection molding, several hours for 3D printing). However, other factors such as the energy consumption for producing the mold, the production volume and material efficiency have to be taken into account. When looking into lower volumes, it becomes a fact that additive manufacturing is a more sustainable production method, regarding energy efficiency.
Sensors: Data for next-gen composites manufacturing
Suppliers of dielectric sensors such as Lambient Technologies (Cambridge, Mass., U.S.), Netzsch (Selb, Germany) and Synthesites (Uccle, Belgium) have also demonstrated their ability to shorten cycle times. Synthesites reported from R&D projects with composites manufacturers Hutchinson (Paris, France) and Bombardier Belfast, now Spirit AeroSystems (Belfast, Ireland), that it was able to reduce the cure cycle for RTM6 by 30-50% based on real-time measurements of resin electrical resistance and temperature, which are converted into estimated viscosity and Tg by its Optimold data acquisition unit and Optiview software. “The manufacturer can see the Tg in real time, so they can decide when to stop the cure cycle,” explains Synthesites director Nikos Pantelelis. “They don’t have to wait to complete a longer-than-necessary legacy cycle. For example, the legacy cycle for RTM6 is 2 hours at 180°C for full cure. We’ve seen that in certain geometries this can go down to 70 minutes.”
ABB’s Paper Mill Technology Helps Renewcell Turn Old Clothes Into New Fabrics
In recent years, the pulp and paper industry has gone from having a reputation of being dirty and environmentally unfriendly to being a leader in sustainability and pollution control. Now the technologies that enabled that transition are being used to help the textile industry too. And the players involved are restarting a shuttered paper mill in Sweden to make it happen, once more providing good-paying jobs for the area.
Renewcell is the Sweden-based scaleup at the center of it all. The company developed a sustainable process that recycles waste textiles into a product called Circulose, whose name is the tip-off that it’s aimed at making fashion circular.
How pioneering deep learning is reducing Amazon’s packaging waste
Fortunately, machine learning approaches — particularly deep learning — thrive on big data and massive scale, and a pioneering combination of natural language processing and computer vision is enabling Amazon to hone in on using the right amount of packaging. These tools have helped Amazon drive change over the past six years, reducing per-shipment packaging weight by 36% and eliminating more than a million tons of packaging, equivalent to more than 2 billion shipping boxes.
“When the model is certain of the best package type for a given product, we allow it to auto-certify it for that pack type,” says Bales. “When the model is less certain, it flags a product and its packaging for testing by a human.” The technology is currently being applied to product lines across North America and Europe, automatically reducing waste at a growing scale.
Humber Zero: decarbonising an industrial cluster
The Humber is an industrial hub with an economy worth £18bn GVA and where one in ten jobs is associated with heavy industry. Two oil refineries, the second largest chemicals and process clusters, and an integrated steelworks all contribute to the Humber being the most carbon-intensive industrial cluster in the UK.
Blue hydrogen is the main focus at Immingham although Phillips 66 is progressing Gigastack, a green hydrogen project separate to Humber Zero that along with project partners ITM, Ørsted and Element Energy aims to generate green hydrogen and electricity from nearby offshore wind and electrolysis.
How Eastman Strives for a Circular Plastics Economy
“Mechanical recycling—where you go out and take items like single-use bottles, chop, wash and re-meld them and put them back into textiles or bottles—can only really address a small portion of the plastics that are out there,” Crawford said. After a few cycles, the polymers in the products degrade and the process is no longer possible.
Instead, Eastman uses advanced, also known as molecular or chemical, recycling. “We unzip the plastic back to its basic building blocks, then purify those building blocks to create new materials,” Crawford said. This “creates an infinite loop because that polymer can go through that process time and time again.”

Material World: A Greener and Smarter Future for Textile Production
The environmental impact of textile production is well documented, with the industry as a whole ranking second only to oil in terms of global pollution levels. Massive energy and water use, together with sky-high levels of discarded chemicals and landfill waste are all key drivers in the calls for closed-loop production.
“3D design packages help designers optimize materials and design for minimal or zero waste, for example through lay efficiencies when laying pattern pieces out, or through calculating how to knit a garment in one piece without any yarn waste. Smart processes can also influence sourcing and supply strategies, for example through using computer algorithms to predicts waste or production inefficiencies, or fabric performance issues.”
Why more manufacturers are turning to microgrids
Microgrids offer manufacturers a flexible platform to head off these issues — ensuring power is reliable, enabling renewable energy for sustainability goals, controlling energy costs and attracting customers and investors that want manufacturers to continuously raising the bar on ESG performance. A microgrid can help control energy generation, usage and cost stability.
A well-designed microgrid can bring efficient, low-cost power as well as reliability and resiliency benefits to critical infrastructure. A microgrid with robust controls and up-to-date cybersecurity supports operational flexibility while providing predictable costs optimized for both efficiency and sustainability.
An investment in a microgrid can act as insurance for continued growth, success and innovation. A power disruption brings vulnerability, loss of time and money — a microgrid puts you back in charge.

Pharma Sets a Foundation for Greener API Manufacturing
To contribute to the reduction of CO2 and GHG emissions, all drug developers and manufacturers need to seriously consider measures to improve sustainability throughout each phase of their industrial processes, according to Weng. “The pharmaceutical industry is due for a major overhaul in all aspects of its unit operations. Essentially, the pharmaceutical industry should be evaluating sustainable alternatives for all current exercises that rely on fossil fuel inputs,” he sates.
The best time to consider optimal, sustainable production solutions is during the design of the synthetic route to an intermediate/API, notes Martin, because once these processes are validated, it is very challenging to introduce any changes, even if they offer significant improvements in productivity and sustainability.
Parts cleaning: the manufacturing maintenance saving you’ve never heard of
“Our new process, developed with the new Automatic Aqueous cleaning machine solution supplied by Safetykleen, reduced the cleaning cycle from 30 minutes down to 7 minutes!,” said a spokesperson at Knorr-Bremse “Not only was the cleaning time reduced but the cleaning is now more efficient and has significantly less environmental impact.”
The use of a parts washer can dramatically decrease the personnel time required for the cleaning component of maintenance and allows maintenance workers to focus on the key tasks of disassembly, reassembly and testing. According to feedback from users, an automatic parts washing machine can complete two days’ worth of manual cleaning in around 3 hours and reduce maintenance personnel requirements by 23%.
Can a Green-Economy Boom Town Be Built to Last?
The epicenter of that boom is an electric-vehicle maker named Rivian, which brought in Mr. Mosier’s company and others in the Normal, Ill., area to work on the city’s costliest construction project in decades: a massive auto plant.
As it prepares to deliver its first electric pickup trucks and sport utility vehicles this year, Rivian has spent around $1.5 billion renovating and expanding a factory once owned by Mitsubishi. On a typical day the 3.3-million-square-foot plant hosts several hundred construction workers alongside more than 2,500 workers employed by the company, which expects to eventually double its local head count.

They’re applying digital and IoT technologies and predictive analytics to build water-resilience management techniques such as flood modeling, sustainable drainage design, clean water distribution, and resource optimization.
The Big Semiconductor Water Problem
Circular Car Factories
The next big shift will be an environmentally friendly movement dubbed the “circular auto factory.” According to some experts, the circular cars initiative will reshape the auto industry during the next two decades, as OEMs and suppliers attempt to achieve net-zero carbon emissions across the entire vehicle life cycle.
The term “circular car” refers to a theoretical vehicle that has efficiently maximized its use of aluminum, carbon-fiber composites, glass, fabric, rubber, steel, thermoplastics and other materials. Ideally, it would produce zero material waste and zero pollution during manufacture, utilization and disposal.
One of the key elements of a circular car factory is a closed-loop recycling program where disassembly lines are housed in the same facility as traditional final assembly lines. All vehicle components and materials are remanufactured, reused and recycled at the end of life.
Circular Economy 3D Printing: Opportunities to Improve Sustainability in AM
Within the 3D printing sector alone, there are various initiatives currently underway to develop closed-loop manufacturing processes that reuse and repurpose waste materials. Within the automotive sector, Groupe Renault is creating a facility entirely dedicated to sustainable automotive production through recycling and retrofitting vehicles using 3D printing, while Ford and HP have teamed up to recycle 3D printing waste into end-use automotive parts.
One notable project that is addressing circular economy 3D printing is BARBARA (Biopolymers with Advanced functionalities foR Building and Automotive parts processed through Additive Manufacturing), a Horizon 2020 project that brought together 11 partners from across Europe to produce bio-based materials from food waste suitable for 3D printing prototypes in the automotive and construction sectors.
How Honeywell's CEO is turning the legacy manufacturer into a SaaS player
Cumulatively, it marked a significant step forward in Adamczyk’s vision to turn Honeywell from a legacy industrial manufacturer into a top software provider for sectors like real estate, life sciences and aviation.
“The one common fiber across all our businesses is we are a controls company,” he told Protocol at an event on Tuesday. “When you’re a controls company, you’re connected to everything, you’re connected to all the systems in that building, in that aircraft. We use that data to drive controls, but we could use that data to drive energy savings, to drive efficiency.”
How to optimize cleaning in place (CIP) duration?
Cleaning systems regularly disinfect the entire production lines. They consist of stainless steel tanks, storage tanks, pumps, valves and piping and integrate connections with the production equipment. In a medium-sized factory, the cleaning stations wash up to 250 pieces of equipment per day to avoid contamination from one batch to another (by bacteria or micro-organisms).
When the equipment is being cleaned, disinfected or sterilised, it is not in a position to produce. CIP thus has a direct impact on the uptime rate of production lines. Furthermore, CIPs require large volumes of water, the scarcity of which is becoming increasingly critical looking at the needs of a factory estimated at several tens of thousands of cubic meters per year. Optimising CIPs is therefore an essential lever for any manufacturer who aims to increase the availability of production lines while significantly reducing its water consumption, in other words to achieve eco-efficiency.
