Paper Recycling, Collection, Quality

The challenges increase, not only for the deinkers among paper mills – it becomes more and more difficult to produce new graphic paper from paper for recycling at economically reasonable conditions. Rising prices for paper for recycling increase the costs, at the same time the availability of graphic paper is going down – people read less newspapers, the newspapers become thinner due to less advertising, and the paper collected for recycling contains more and more packaging. The municipalities sometimes take advantage of new legislation to discourage locally competing selective collectors who deliver especially preferred quality. Concerned about the quantity of their supplies it becomes more and more difficult for the paper mills to keep up their requirements for high quality. A helpful aspect is the increasing importance of ecolabels such as the Blue Angel or the EU Ecolabel for printed products, for which also the removability of printing inks has to be proven.

2018 01 15 100526Quality is not only important for deinking grades, also the manufacturers of corrugated papers and board face the challenge to meet the rising demand at an acceptable quality, mainly for the increasing need for all kinds of packaging. A possible source for high quality paper for recycling is the fraction today known as mixed paper. How can, already by a more selective collection and sorting at the consumer, the yield be increased for the different grades, suitable for the different products? Here it is of some help to know the material flow: Where do the different fractions of paper for recycling end up, that are so valuable for the different grades to be produced?

New digital printing processes are a perennial issue at the INGEDE Symposium in Munich: Mostly the inks and therefore also their behaviour in the deinking process differ fundamentally from traditional offset and gravure inks. While dry toners (from laser printers) are generally good deinkable, some inkjet prints create problems. But here a lot has been achieved within the last years, some manufacturers have improved their processes and inks significantly. David Croll of Océ Printing Systems will present the history of inkjet printing and new, better deinkable inkjet processes at the symposium.

Undeinkable Prints can Create Problems in the recycling Process

Some might remember that prints with liquid toner from HP Indigo are not suitable for the deinking process. Similar problems can arise from UV-curable inks – here the inks cross-link due to a polymerisation induced by UV light sources. In many cases the resulting large particles are not sufficiently separable, also because they are not as water-repellent (hydrophobic) compared to traditional offset inks. But also here some differences can be observed; at the INGEDE Symposium the reasons for the increasing prevalence of UV-cured prints and the resulting problems will be discussed.

2018 01 15 100756Quality of Paper for Recycling Continues to be a European Issue

Different collection rates in different European countries continue to be a challenge. In his keynote presentation, Ulrich Leberle of CEPI in Brussels will explain the measures for a circular economy that the European Commission aims at together with the European paper industry.

Paper Industry 4.0: The Digital Revolution in Papermaking?

The classical process optimisation undergoes a revolution. There are new and better answers to old questions, better than ever: Jürgen Käser, Voith’s expert for the paper industry 4.0, will present these answers. Which kind of raw material composition will reduce production costs without harming productivity? What is the relationship between the frequency of tear-off and the way the plant is being run? What application of primary energy is absolutely necessary for a certain grade? Novel mathematical modelling in real-time lead to new process dynamics, this results in highly stabilised and cost effective production processes – not to be reached by human hand so far. And the first practical applications show: Also papermaking is at the edge of a digital revolution.

Since its establishment in 1989, INGEDE for more than 25 years now deals with the common problems of the deinkers. INGEDE has become well known also for the development of test methods that in the meantime have become established and reliable international standards. Many ecolabels for printed products are based on these standards.

Toscotec is confirmed as global supplier of Steel Yankee Dryers, with installations across five continents. 

Encore tissue started up a new Toscotec Steel Yankee Dryer on ET3 at its Laverton North mill, Melbourne, Australia. The rebuilt tissue machine started producing high quality tissue paper immediately after start-up. The Australian tissue maker purchased a second generation TT SYD of 3600 mm diameter, to replace an existing cast iron Yankee.

2018 01 11 132832

Following the installation of Toscotec’s steel Yankee dryer, Encore Tissue expects to increase the machine operating speed from 1,400 mpm to 1,900 mpm. They also expect an increase in production and machine efficiency, and a real improvement of the finished product quality, from the point of view of homogeneity of the tissue structure.

With this sale, Toscotec sets a new important record in the steel Yankee dryer market: 203 TT SYD sold in 36 countries across five continents.

Marco Dalle Piagge, Toscotec Sales Director, stated: “In the year 2000 we installed the first steel Yankee dryer in Italy. Eighteen years on, we have TT SYD running in mills all over the world. We are proud of the technological revolution we have pioneered and of the journey - certainly not without obstacles – that led our company to an unquestioned leadership in the tissue market.

Stefano Marenco, Toscotec R&D Director, stated: “What we have achieved is an important recognition, but it will not be the end of the road. Toscotec is always looking for solutions that can improve the tissue process and reduce the energy cost. TT SYD is not an exception. Our R&D department is abuzz and there will be new developments soon.

Let's have a look at the new video!

As part of its strategy to expand into the tissue segment, Suzano Papel e Celulose, the world’s second-largest eucalyptus pulp producer, commissioned Voith Paper, a global technology leader in innovation for the paper industry, to supply complete production lines for the manufacture of sanitary (tissue) paper.

An Environmentally Friendly Replacement for Polycoated and Waxed Papers!

Moisture is a major threat to raw materials and finished goods of all kinds—particularly those made of metal and prone to rust and corrosion. Greases and oils sometimes used as lubricants or rust preventatives on metal components add another problem by threatening to leak through packaging and contaminate surrounding areas. Waxed or polycoated papers are traditional moisture-resistant packaging options for problems like these. However, such coated papers pose an environmental problem because they are not recyclable and repulpable. Even if recycled back into the pulp and paper stream, they would first have to go through a costly process of separating the paper base from the coating.

To avoid this environmental problem, Cortec® Corporation has developed an environmentally acceptable replacement to unrecyclable polycoated and waxed papers. Cortec’s new high gloss EcoShield® Super Barrier Paper and Linerboard relies on a water-based moisture barrier coating for moisture resistance. The technology makes the paper fully recyclable and repulpable without requiring costly processes to remove the coating from the paper. In addition to recyclability, Cortec’s EcoShield® Super Barrier Paper and Linerboard demonstrated better water vapor barrier properties than polycoated paper and waxed paper during testing.

2018 01 11 071711 2018 01 11 071745 2018 01 11 071812

To evaluate the moisture resistance of EcoShield® Super Barrier and Linerboard, the barrier paper was tested against a comparable polyethylene coated paper and a commercial waxed paper according to ASTM E-96 at 73°F (23°C) and 50% relative humidity. The EcoShield® Super Barrier Paper and Linerboard showed a water vapor transfer rate of 0.32-0.37 grams per hour on a square meter of paper. A polycoated paper in the same test allowed slightly more water vapor to pass through in the same time frame, at the higher rate of 0.47-0.71 grams per hour.  The waxed paper was much less resistant to water vapor, allowing it to transfer at a rate of 6.5-6.9 grams per hour on the same size of paper. Though it is not intended for applications involving constant water contact, the shiny side of EcoShield® Super Barrier Paper and Linerboard also has the ability to repel liquid water. Its TAPPI T-441 Cobb Water Absorption rate is less than 0.3 grams of water per square meter in 2 minutes.

EcoShield® Super Barrier Paper and Linerboard also has excellent oil and grease resistance. It registers a high kit test value of 12, representing the highest amount of an aggressive liquid solution to remain on the paper surface without causing the paper to fail. The high gloss paper not only protects against the ingress of moisture or grease into a package, but it also protects against the leaching of oil and grease out of a package. This is important when manufacturer’s specifications require the use of greasy rust preventatives, or when the metal equipment being wrapped, packaged, or shipped contains lubricated parts. EcoShield® Super Barrier Paper and Linerboard can discourage these oils and greases from seeping out of the package and causing packaging failure or contamination of nearby materials.

The versatility of EcoShield® Super Barrier Paper and Linerboard as a flexible, moisture barrier material allows it to be used for a variety of packaging applications and beyond:

•    Protecting moisture sensitive components
•    Wrapping oily or greasy parts
•    Lining wood pallets or corrugated boxes
•    Packaging products
•    Keeping work surfaces clean with a disposable cover

EcoShield® Super Barrier Paper and Linerboard is available in custom sizes and as sheets or perforated rolls for the convenience of the user.

Whether moisture threatens from the inside or the outside of a package, EcoShield® Super Barrier Paper and Linerboard is a more environmentally friendly way to protect against damage from moisture, grease, and oil. By coating water based barrier technology onto biobased material, Cortec® has made a fully recyclable, environmentally acceptable, and competitively performing replacement for polycoated and waxed papers.

Levelling the playing field for the U.S. industry, Canadian uncoated groundwood paper imports to now require CVD deposits to enter the country legally

North Pacific Paper Company has just commended the U.S. Department of Commerce for its preliminary countervailing duty (CVD) determination covering subsidized uncoated groundwood papers from Canada. As a result of these determinations, the Department of Commerce will impose tariffs on imports of uncoated groundwood papers to offset the unfair advantage provided by Canadian government subsidies.

2018 01 10 064711“Today’s affirmative decision by the Department of Commerce confirms that Canadian uncoated groundwood papers benefit from significant levels of government subsidies,” said Craig Anneberg, CEO of NORPAC. “What the U.S. uncoated groundwood papers industry wants is a level playing field, and this decision is an important step forward for American producers, workers and their families that have been the victims of unfair Canadian trade practices for too long.”

The Department of Commerce found that Canadian uncoated groundwood paper was subsidized by an average of 6.53 percent.

“NORPAC has a world-class facility that can compete with anyone around the world, but we need to be able to compete on a level playing field. This decision will protect American jobs in Washington, Mississippi and Georgia, and may even serve to create jobs in the U.S. as idled paper machines restart,” said Anneberg.

Today, there are groundwood paper mills operating across the U.S., primarily located in Washington state, Georgia and Mississippi, which support family-wage jobs and countless community businesses and supporting industries.

In the face of unfair competition since 2012, more than ten American mills have closed costing approximately 2,150 jobs, reducing the U.S. groundwood paper industry’s production capacity by nearly 70 percent. During this time, U.S. producers’ share of the American market has plummeted from 60 percent to 36 percent. 

The U.S. uncoated groundwood papers industry and NORPAC are not alone in seeking and finding relief from unfair trade. Today’s Department of Commerce decision follows similar trade cases in the last five years, which also found that supercalendered papers and softwood lumber imports from Canada were being subsidized causing material injury to U.S. manufacturers and jobs. Other cases found that imports of foreign coated and uncoated papers were also being subsidized causing injury.

“While we understand the concerns recently surfaced by some newspaper publishers, we strongly disagree with the notion that their industry requires low-priced, government-subsidized, imported newsprint from Canada to sustain its business model. High-quality journalism in communities across the country should not depend on unfairly traded inputs that cause material injury to a U.S. industry and American jobs,” added Anneberg. “We estimate the impact this ruling would have on the cost to produce the average printed newspaper would be less than $.05 per newspaper – a small price to pay to preserve American manufacturing jobs.”

Continuing to innovate, retool and invest for the future, NORPAC operates one of the largest and most efficient paper mills in the U.S., which produces a broad range of high-quality papers to customers across the United States and around the world. Recently, the company unveiled affordable, sustainable Natural Choice Paper™, which is made with a process that yields twice as much paper from the same amount of wood, compared to standard copy paper.

“NORPAC is one of the largest employers in rural Southwest Washington and Northwest Oregon,” concluded Anneberg. “These are strong, family-wage manufacturing jobs that cannot be replaced in a rural community that faces some of the highest unemployment in the region.”

On August 9, 2017, NORPAC filed antidumping and countervailing duty petitions with the U.S. government. The Department of Commerce will issue its preliminary determination in the companion antidumping investigation on March 7, 2018. The Department is expected to make final antidumping and countervailing duty determinations in July 2018, and the International Trade Commission will make its final injury determination in August 2018.

WestRock to Upgrade Florence, SC Mill

WestRock Company, a leading provider of differentiated paper and packaging solutions, has just announced a planned investment in its Florence, South Carolina kraft linerboard mill that will significantly increase the mill’s efficiency, quality and service levels.

2015 10 18 094836The $410 million investment over two years will include installing a 330” state-of-the-art kraft linerboard machine and related infrastructure that will replace three older, narrow-width paper machines. The company expects the new machine to produce 710,000 tons of kraft linerboard annually. In addition, the company plans to invest approximately $60 million over the next five years to support the new machine and other mill projects.

When coupled with the recently completed modern woodyard, the Florence mill will become one of the lowest cost kraft linerboard mills in North America. 

“This investment will make our Florence mill a state-of-the-art manufacturing facility, sustaining good manufacturing jobs and promoting the long-term success of the mill,” said Steve Voorhees, chief executive officer of WestRock. “The support of the Florence County Economic Development Partnership and the South Carolina Department of Commerce helped make this investment possible and is greatly appreciated.  We look forward to contributing to the Florence community for many years to come.”

“Any time a company invests in our state, it shows a commitment to our citizens that we couldn’t be more grateful for. This investment is something that South Carolina should be proud of, and we know that the future is bright for the partnership between our state and WestRock,” said Henry McMaster, governor of South Carolina.

“WestRock is not only a leader in the packaging industry, but also a respected name in South Carolina’s overall business community. Today, I’m thrilled to congratulate this great company on their continued success in the Palmetto State,” said Secretary of Commerce Bobby Hitt. 

“WestRock supports hundreds of jobs in Florence County and remains one of our top employers. We are very pleased that this industry will continue to be an important part of Florence County’s economy,” said Florence County Council Chairman Kent Caudle.

“Florence County is excited about WestRock and its investment in our area – one of the largest in recent history. This is a significant development for the people of Florence County,” said Florence County Economic Development Partnership Chairman Frank J. “Buddy” Brand.

“This new investment is an important step for Florence County in preserving jobs that support so many families in our community, and is evidence that companies that come to Florence stay in Florence. I’m very pleased that this project will help sustain the significant economic progress that Florence has made in recent years,” said South Carolina Senate President Pro Tempore Hugh K. Leatherman.

The new linerboard machine will be housed in a building adjacent to the existing complex, and the company expects production on the new linerboard machine and the shutdown of the three existing machines to occur in the first half of calendar 2020.

In 2016 Smurfit Kappa awarded Toscotec with the rebuilding of the Company´s Barbosa paper machine’s dryer section. The target operating speed of the machine after startup was set at 1,000 mpm.

Following an extensive project that lasted 25 months, with 36 days of setup from paper to paper, the PM was successfully commissioned and started up in July 2017. 

2018 01 04 081259

The main target of the project was to improve the efficiency of the PM, by increasing its operating speed and production. The alliance between Toscotec and Smurfit Kappa has lead the packaging company to increase containerboard production to 120,000 tonnes per year which means an increase in the corrugating machines production.

Enrico Fazio, Toscotec’s Paper & Board Sales Manager stated, “Toscotec’s long-standing experience in dryer section rebuilds, using TT SteelDryer, our unique dryers with an extremely high drying capacity, and the advanced rope-less tail threading system, was the deciding factor in the customer’s choice. We are very proud of our partnership with Smurfit Kappa and we would like to thank the SK team in Barbosa for their great cooperation during the entire project”.

According to Carlos Mario Londoño, the project manager, "This was a very complex project to carry out. Thanks to the collaboration of suppliers such as Toscotec, we achieved the our goal within the time we had established”.

WestRock Company (NYSE:WRK) has just announced that it has completed its previously announced acquisition of substantially all of the assets of Plymouth Packaging, Inc. (“Plymouth”).

Wet and mild weather in the fall and early winter has led to a shortage of pulpwood in late 2017 and early 2018.

billkorlogoThe root cause of the shortage of pulp wood is the unusually wet and mild start of the winter. Normal winters the ground freezes which allows for efficient forestry. At present, forestry machines cannot be used in the forests in certain areas. In addition, the possibility of driving on the forest road network is limited in some areas, which also reduces the flow of wood. The situation is the same in the Nordic countries, western Russia and the three Baltic states.

BillerudKorsnäs has taken measures to minimize the effects of the lack of pulpwood and follows the situation on a daily basis. The measures taken are mainly mix changes in production and redistribution of flows to optimize the use of wood.

"We have the opportunity to change the product mix in our production to optimize wood usage. This is something we look over every day but what we now do from the perspective of economizing wood, especially short fiber. To the plant in Gävle we have also imported eucalyptus chips from South America, something that has been evaluated to be used in this type of situations that historically happens every 5-10 years, "says Uno Brinnen, Senior Vice President Forestry, BillerudKorsnäs.

The financial impact on Q4 2017 results is minor and it is difficult to assess the extent of the lack of pulpwood and how long the situation will last but given current assessments the estimated negative impact on earnings in Q1 2018 is approximately SEK 80-100 million.

Valmet has introduced a predictive tool for detecting recovery boiler leaks - Valmet Recovery Boiler Leak Detector. This innovative diagnostics application with advanced analytics enables boiler owners to detect even the smallest tube leaks in an unprecedented way, resulting in significantly improved boiler safety and reduced damage risks.

valmet logoTypically, distributed control systems (DCS) have only relatively primitive tools for recovery boiler leak detection. These include simple differentials between the feedwater and the steam, or alarms for low drum level and high furnace pressure that are activated only in the case of very large and sudden leaks. With these traditional tools, it is virtually impossible to notice a minor leak in the boiler furnace. A small undetected leak may grow, rupture a tube and lead to severe damages or even to a major smelt-water explosion. 

"Valmet Recovery Boiler Leak Detector now takes leak detection a major step forward by combining advanced mass and chemical balance calculations. This makes it an invaluable diagnostics tool for detecting leaks at their early stages," says Timo Laurila, Business Manager, Recovery Analyzers and Advanced Process Controls, Valmet.

Currently, the leak detection solution is used by several pulp mills, and the results gained with it have been very positive.

Technical information about Valmet Recovery Boiler Leak Detector

Valmet Recovery Boiler Leak Detector typically recognizes a 0.25-0.50% difference between the feedwater and the steam in the feedwater flow. Additionally, the application features an advanced chemical balance calculation, which enables higher accuracy and identification of critical leaks and separation from non-critical leaks. The balance is typically calculated using phosphate as a tracer.

Alarm levels can be set low enough so that a leak can be diagnosed before a tube is ruptured. As boiler load swings are taken into account, there are no unnecessary alarms due to changes in load.

Leak rate monitoring and alarms can be tested safely during normal operation by using a blowout line for leak simulation. Operator instructions and training for boiler leak detection and management are included in the delivery scope.

Valmet Recovery Boiler Leak Detector is part of the Valmet Recovery Boiler Optimizer product portfolio and can be implemented on any DCS.

Valmet is the leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries. We aim to become the global champion in serving our customers.

Valmet's strong technology offering includes pulp mills, tissue, board and paper production lines, as well as power plants for bioenergy production.
