Supporting and Developing Sustainable Industrial Processing in Pulp and Textiles

In the past several years, Kadant has continued to expand its operations with a major focus on Sustainable Industrial Processing®. In fact, Kadant has been nominated as one of America’s Most Responsible Companies for 5 years in a row. These rankings consider several factors across Kadant operations, but a key component of these evaluations is an environmental score. Now, not only has Kadant been present on this list for 5 years running, but our environmental score has also continually increased among other factors.


Within the Black Clawson division of Kadant, we directly support these efforts. We supply products and solutions that directly support paper recycling. What is already remarkable about this industry is that according to the United States EPA, corrugated boxes had a recycling rate of 96.5% in recent years. On a holistic view, 46 million tons of paper and paperboard were recycled in 2018, which is the highest recycling rate amongst other materials categorized as Municipal Solid Waste. This rate has remained relatively constant in spite of American recycled paper export rates decreasing and becoming more volatile since 2018 thanks to a significant amount of recycled paperboard production has come online since that time.

Kadant has been a major supporter of North American efforts to continually increase recycling rates with challenging feed stocks of mixed papers, and other highly contaminated fiber sources. These recycling rates make us proud to be part of such sustainable industries and the facilities that make this happen.


Tornado Pulper’s Role to Support Sustainability


The Tornado Pulper fits directly into the Kadant goal to promote Sustainable Industrial Processing. In the forward-thinking approach integral to Kadant Black Clawson’s success for so many years, we see a critical need to prepare our products and offerings to support enhanced recycling capability of difficult to defiber paper products, and textiles.


As noted previously, in the last several years the recycling rate has remained relatively consistent at 46 million tons per year. Recycled paper mills are becoming larger and better equipped to handle highly contaminated furnishes to support this continued growth and sustainability.


Nonetheless, some paper streams are still problematic to handle such as wet strength treated papers as well as other barrier coatings that are required for the performance of paper-based products in demanding applications. Some conventional technologies exist that can be used for wet strength, but it is no secret that the material is difficult to process. In a 2021 Recyclability Guide from AF&PA, wet strength resins were outlined as a significant recycling challenge in corrugated packaging, boxboard, carrier board, kraft sacks, and molded products. Those that operate recycled paper lines know that significant wet strength in the recycle stream can lead to yield loss, impacting the bottom line of operations.


As we look toward the future of reduced reliance on plastics for packaging, food and beverage containers, and other specialty products, it will be necessary to be capable of handling the increased volume of these specialty treated products which can be challenging to repulp.


The Tornado Pulper brings Kadant to the forefront of the Sustainable Industrial Processing required to make these items recyclable. Utilizing a rotor and stator to efficiently disintegrate these materials in a wet environment, the Tornado pulper, aided by the pumping action of the rotor and stator to produce a recirculated flow, provides rapid size reduction of difficult to pulper materials. All these features combine to allow the Tornado to pulp materials that are otherwise extremely problematic.

Textile Recycling Rates



Textile recycling lags that of paper significantly, but at the heart of these materials is the same make-up – cellulose. Clearly, taking old jeans, t-shirts, and other cotton-based clothing items and recycling them into new products is a challenge due to the structure of the articles, and their long fiber lengths (relative to wood fibers).


So, while paper recycling rates continue to be sustained and increased each year, we see minimal changes in recycling rates for textiles relative to the explosive increases seen for paper grades from the 1990’s through the mid-2000’s. We also see landfill rates of textiles rapidly outpacing the growth of recycling rates.

Again, referring to EPA estimates, only 14.7% of textiles were recycled in 2018. Meanwhile textiles represent 5.8% of total MSW generated, or 17 million tons, and only 2.5 million tons were recycled.


Overall, the North American market tends to feel less pressure related to landfill costs, which varies by region. Meanwhile, mandates in Europe indicate this issue will be coming to the forefront of industry to address. North America may lag with this challenge, but it is ultimately a matter of when.


The Tornado Pulper allows Kadant to be on the forefront of supporting the increase of sustainable recycling of these materials.

Benefits and Pitfalls of Machine Health Monitoring

Machine health monitoring involves the continuous observation of machinery performance through sensors and data analytics to predict failures, optimize maintenance schedules, and improve overall productivity.

 

In the context of paper pulp processing, an industry where complex, high-speed, and often harsh machinery operates, the integration of machine health monitoring systems offers a range of potential benefits but also presents certain challenges. Understanding both the advantages and pitfalls of such systems can help manufacturers make informed decisions about their implementation.


Benefits


“Forewarned is forearmed”


Predictive Maintenance and Reduced

Downtime

The primary advantage of machine health monitoring is predictive maintenance. Paper pulp production relies on large, expensive machines such as pulpers, refiners, and paper machines, which operate under heavy mechanical stress. By using sensors to track parameters like vibration, temperature, pressure, and wear rates, machine health monitoring systems can predict when a machine is likely to fail. This allows operators to schedule maintenance before a failure occurs, thus avoiding unexpected downtimes. Predictive maintenance has been shown to reduce unplanned shutdowns, which are especially costly in continuous manufacturing environments like pulp production.


Equipment-related failures account for more than 35% of unplanned downtime incidents in manufacturing.

“Measure twice, cut once”


Enhanced Equipment Longevity

Continuous monitoring of equipment allows for the early detection of minor issues such as misalignment, imbalance, or increased wear on components. Identifying these issues before they escalate into more severe damage prolongs the life of critical machinery, resulting in reduced capital expenditure on replacements. Given the substantial cost of machinery in pulp processing, this can lead to significant long-term savings.

 

“A stitch in time, saves nine”


Energy Efficiency and Cost Savings

Energy consumption is a significant operational cost. Machine health monitoring can help optimize machine performance, ensuring that the equipment operates within optimal parameters. For instance, it can detect inefficiencies caused by friction, wear, or underperformance in certain parts of the process. As energy consumption is directly related to machinery performance, ensuring the system runs smoothly translates to less energy waste. Optimizing energy usage not only cuts operational costs but also supports sustainability efforts by reducing the carbon footprint of production.


The average cost of unplanned downtime reached $260,000 per hour in 2024.

“For wont of a nail”


Improved Safety

Heavy machinery and chemical processes can pose safety risks. By constantly monitoring the health of these machines, health monitoring systems can identify dangerous anomalies, such as overheating or unusual vibrations, which might indicate potential failures. Early detection of such conditions allows for timely intervention, preventing accidents, fires, or explosions. This contributes to a safer work environment for employees, reducing the likelihood of costly injuries and downtime.


“Mind your p’s and q’s”


Data-Driven Decision-Making

Machine health monitoring systems generate large volumes of real-time data that can be analyzed for insights. In pulp processing, where several machines are operating in tandem, having access to such data allows managers to optimize the entire production line. Real-time monitoring provides a clearer picture of the system’s health, enabling better resource allocation, workload balancing, and inventory management. Furthermore, the data can be used to identify trends, enabling more accurate forecasting and long-term planning.


Pitfalls


“The cost of success is far cheaper than the price of failure” 


High Initial Investment

One of the main drawbacks of implementing machine health monitoring systems is the high upfront cost. Installing sensors, data collection infrastructure, and analytics platforms can be expensive. For small to medium-sized mills, the initial investment can be a significant financial burden. Additionally, integrating these systems into legacy equipment may require upgrades or even the replacement of older machinery, which adds to the cost.


“Too much, too soon” 


Data Overload

Machine health monitoring systems generate vast amounts of data. While this data can be invaluable, the sheer volume can also be overwhelming. Without effective data management and analytical tools, companies might find it difficult to extract meaningful insights. This can lead to “data overload,” where operators are inundated with information but lack the ability to identify actionable insights. In a fast-paced production environment like paper pulp processing, this can reduce the effectiveness of the system rather than enhance it.


“To be unprepared for success is to be prepared for failure”


Skill Gap and Workforce Training

Implementing machine health monitoring systems requires skilled personnel who can interpret the data, maintain the monitoring system, and act on its insights. In industries where workforces may not have a background in data analytics or advanced machinery diagnostics, there may be a gap in required skills. Companies will need to invest in training employees or hire specialists, which can incur additional costs and potentially disrupt normal operations during the transition period.


“Maintenance is the art of preserving excellence”


System Reliability and Maintenance

While machine health monitoring can improve the reliability of equipment, the monitoring systems themselves are not immune to failure. Sensors can malfunction, data transmission can be interrupted, or software glitches can occur. If the monitoring system fails or provides incorrect readings, it can lead to erroneous decisions, such as overlooking a pending failure or scheduling unnecessary maintenance. Furthermore, maintaining and troubleshooting the monitoring system itself adds a layer of complexity and cost.


“There is nothing so simple that cannot be misunderstood”


Integration Challenges

Integrating machine health monitoring systems with existing production management systems can be difficult. In many facilities, there are various pieces of machinery from different manufacturers, each with its own communication protocols and data formats. Ensuring seamless integration between these disparate systems can be a time-consuming process. Moreover, if integration is not done correctly, it can lead to data silos, where useful information from different systems cannot be shared or analyzed effectively.


“To thine own self be true” 


Conclusion

Machine health monitoring offers significant benefits to paper pulp processing, particularly in terms of improving maintenance practices, enhancing equipment longevity, reducing energy consumption, and ensuring safer operations. However, it is not without its challenges, such as the high initial investment, potential data overload, and the need for skilled personnel.

 

To maximize the benefits of these systems, companies must carefully weigh these factors and invest in proper training, system integration, and data management strategies. When implemented effectively, machine health monitoring can serve as a powerful tool for enhancing productivity and reducing operational costs.

Unplanned Downtime


Everyone knows that unplanned downtime is expensive, but many still choose to ignore it. Modern machine health monitoring is an excellent way to at least eliminate the excuses. Even airlines use it to monitor engines in flight. Perhaps they take it a little more seriously, or perhaps we should say mill managers should take it more seriously. Either way, you procrastinators are running out of excuses!
