Jofo Nonwovens Acquisition of PFNonwovens Includes Face Mask Line In Europe

Jofo Nonwovens, based in Weifang, Shandong, China, will acquire PFNonwovens' Wuxi, China-based nonwovens operation. PFNonwovens acquired the operation from First Quality Nonwovens in 2018. First Quality started making spunmelt nonwovens in Wuxi in 2013.

Jofo, fast growing and leading nonwovens supplier in China, has four manufacturing sites in Asia. With the transaction, Jofo is expecting to enter into growing medical sector on top of its existing hygiene and industrial businesses.

PFN is a global leading producer of nonwoven textiles with operations in Europe, USA and Africa. It will continue, post transaction, to supply nonwovens worldwide to its customers in absorbent hygiene with a focus on premium infant care, adult incontinence, feminine hygiene and medical protective products for the retail and health care markets.

“PFN Wuxi is a very well managed site with a strong team and very good location," says Rain Tian, CEO of Jofo. "This transaction takes Jofo entering into medical nonwoven market in Asia and provides more capacity to address the growing demand of our existing customers. Also, a strong logistic position in East China region will enable Jofo to support the customers in that region better. We commit to invest strongly in Wuxi site to make it a strong manufacturing base with more new capacities and technologies to better serve our customers.”

“This transaction will enable us to fully focus on supporting our global customers in their key markets, as we continue to build on PFN`s core strengths, namely high value added and innovative products. It will allow us to bring forward the building of two new production lines in North America and Europe to increase our production capacities in absorbent hygiene and the medical segment," says Allen Bodford, CEO of PFN. "In addition, we will continue our expansion into Africa with our new South African line, which started its commercial production in Q4 2019. We are very pleased that we are passing on the Wuxi plant to a strong Chinese investor with plans to expand capacity and to build out the facility. We would like to also express our sincere appreciation and gratitude to our entire workforce in China for all their great work over the years.” 

In April, PFN announced it was adding a Reicofil 5 spunmelt line in the U.S. and a meltblown asset in the Czech Republic. The U.S. investment will largely target medical and hygiene applications while the Czech line will make materials for face masks and medical wipes, which will be made available to the Czech government as well as private customers.

Team at ASU Uses Wastewater to Track Coronavirus and Single Out an Individual Among Two Million

Recently, researchers from the Center for Environmental Health Engineering at Arizona State University's Biodesign Institute have developed a new approach to monitoring regional levels of SARS-CoV-2—the virus that causes COVID-19.

The research is being conducted through a partnership between the university and the City of Tempe, Arizona.

Led by Professor Rolf Halden, who directs the Biodesign Center for Environmental Health Engineering and teaches in ASU’s School for Sustainability and the Built Environment, and Olga Hart, lead author of the new study and a researcher in the Biodesign Center for Health Engineering, the team has begun developing a new monitoring approach for the novel coronavirus, among other dangerous pathogens and chemical agents, in wastewater.

Our results show that exclusive reliance on testing of individuals is too slow, cost-prohibitive and in most places, impractical, given our current testing capacity,” Halden said. “However, when preceded by population-wide screening of wastewater, the task becomes less daunting and more manageable.”

In their redefined method, known as wastewater-based epidemiology, the researchers collect sewage samples so that clues can be analyzed over human health, and can even detect levels of coronavirus infection at both a local and global scale. The high sensitivity of the type of study is also reported to have the potential to detect the signature of a single infected individual among 100 to 2 million persons.

According to ASU, the research method could lead to real-time monitoring of disease outbreaks, resistant microbes, levels of drug use or health indicators of diabetes, obesity and other maladies.

The process works by first transcribing coronavirus RNA into complementary DNA (cDNA) by the reverse transcriptase enzyme, then amplifying the resultant DNA to improve signal detection. This step is followed by the use of sequencing techniques to confirm viral presence in the wastewater samples.

When probing for the SARS-CoV-2 virus, the wastewater is screened for the presence of the virus’ nucleic acid fragments. The RNA genomes are amplified through a process known as reverse-transcriptase quantitative PCR (RT qPCR).

"We can, in one go, monitor an entire community for presence of the new coronavirus,” Hart said. “However, trade-offs exist. To get the best results and avoid loss of information, we want to measure close to virus hot spots and take into account wastewater temperature and dilution when estimating the number of infected cases."

Already, the university suggests that each person infected with SARS-CoV-2 will excrete millions, possibly billions, of viral genomes into wastewater per day, based on estimates on European and North America data. Given those chances, researchers have translated that number to landing somewhere between 0.15 and 141.5 million viral genomes per liter of wastewater generated.

Using this type of monitoring system, along with RT qPCR, researchers predict that they could detect the coronavirus with high sensitivity, simply by monitoring roughly every 1 in 114 individuals in the worst-case scenario and just one positive case among 2 million noninfected individuals under optimum conditions. The information collected would be able to help pinpoint viral hotspots so that resources could better be directed to vulnerable populations, while restrictions could be eased in virus-free regions.

Although the research has since been published in an issue of the journal, Science of the Total Environment, the team has also created OneWaterOneHealth, a nonprofit project of the ASU Foundation that seeks to bring COVID-19 testing to those who currently cannot afford it.

Halden reports that using the ASU-designed screening, roughly 70% of the U.S. population could be screened for SARS-CoV-2 through monitoring the country’s 15,014 wastewater treatment plants at an estimated cost for chemical reagents of $225,000.

Once hotspots in the nation are targeted, testing individuals using clinical methods could then be implemented.

Schools Reopen with Partitions but What About Laminar Air Flow and filtration?

The Pima County superintendent, Dustin Williams, toured a charter school and was impressed that the  Da Vinci Tree Academy had installed partitions. 

Partition 2

The question McIlvaine keeps asking is what consideration is there of laminar air flow.  Partitions can keep virus laded air in suspension.

Many industries are proceeding as if the virus is contained in big droplets such as rain when instead much of the danger comes from aerosols smaller than cigarette smoke.

Lydall has Multiple COVID Initiatives Including Long Term Meltblown Contract with Honeywell not 3M

In our May 29 Alert we had 3M in the title when it should have been Honeywell. In the text we did accurately quote CEO, Sara A. Greenstein “In May, we secured a major long-term agreement with Honeywell to supply meltblown filtration media for their N95 mask production facilities. Our proven technical and production capabilities were key factors in our selection. As a result, we have already committed additional capital to acquire a new meltblown production line to satisfy this and related demand.”

Honeywell has Contract with State of Colorado

Last week Colorado Gov. Jared Polis announced a partnership with Honeywell that will bring millions of N95 face masks to the state.

Honeywell, will produce 6 million masks for health care workers in the state, the governor said.

The masks will “keep our front line health care workers safe,” Polis said, attributing the 17-month contract to his administration’s Innovation Response Team.

The governor added he’s been in continued contact with the federal government about receiving more personal protective equipment.

“I also joined the vice president on a call  where I talked about continuing our partnership with the federal government to supply high-quality PPE to our nursing homes,” he said. “They received their first shipment; they’ll be receiving an additional shipment shortly.”

Nursing homes across the nation and in Colorado have been hit hard by COVID-19, with one analysis finding 57.5 percent of all deaths from the virus in Colorado occurring in long term care facilities.

More than 25,000 Nursing Home Deaths from COVID

The federal government has begun sharing its tracking data for nursing home fatalities for the first time since the novel coronavirus outbreak, a step long urged by members of Congress as an important way to guide efforts to protect the elderly and frail as the nation tries to reopen.

“Without this information, adequate testing and a full supply of personal protective equipment, our seniors will continue to suffer,” U.S. Sen. Bob Casey, a Pennsylvania Democrat, said last month.

The new, initial numbers from the Centers for Disease Control and Prevention and Centers for Medicare and Medicaid Services were shared in a letter to U.S. governors dated Sunday and obtained by ABC News. The numbers document that at least 25,923 nursing home residents have died as a result of COVID-19, though the figure doesn't include reporting from some states prior to May and differs from state-by-state reports due to disparities in the way data is tracked.

The federal regulators also acknowledge their first release of figures may account for about 80% of the nation’s nursing homes, and that “data maybe inconsistent with state data, particularly state death data.”

The survey is the first to include the number of nursing home staff killed in the outbreak, which federal officials list at 449 fatalities across the country. And it marks the first public accounting of deaths in 10 states that were not previously publishing any data about the outbreak’s severe impact on those in long-term care facilities during ABC News' most recent survey.

Along with the new figures, the federal agency that regulates nursing homes told governors they intend to step up penalties and enforcement of infection control efforts. Problems containing infections using trusted methods, like frequent hand-washing and changing gloves and masks, have surfaced frequently during inspections of facilities where there have been deadly coronavirus outbreaks. In inspections, multiple facilities have been shown not to be using certain infection control methods properly.

The federal totals remain lower than the numbers gathered through a state-by-state analysis conducted by ABC News in mid-May. That survey found more than 37,600 deaths attributed to the coronavirus in nursing homes and long-term care facilities from 40 states and the District of Columbia stretching back to the beginning of the crisis.

Just over 100,000 total coronavirus deaths in the U.S. have been reported since the outbreak reached America's shores, according to a tally by Johns Hopkins University.

The new federal count shows that in the 10 states that were not reported nursing home fatalities during ABC News' last survey of national data, an additional 794 residents and staff have died. Those states are Alaska, Arizona, Delaware, Hawaii, Idaho, Kansas, Maine, Montana, Missouri and Utah.

As Florida Reopens Nursing Home Deaths Rise

Over the most recent week, elders living in long-term care facilities accounted for seven in 10 Florida deaths resulting from the coronavirus, as the pandemic increasingly became a scourge of the old and frail.

Though the cumulative overall number of deaths attributed to COVID-19, the illness caused by exposure to the coronavirus, doubled in May, coronavirus deaths at nursing homes and assisted living facilities tripled. As of Monday, 1,236 people at long-term care facilities had died from COVID-19.

One Third of 43,000 COVID Deaths in UK were in Nursing Homes

More than 43,000 people have suffered deaths linked to COVID-19 across the United Kingdom, underlining the country’s status as the worst-hit in Europe.

At least 13,500 deaths linked to the novel coronavirus — nearly 1 in 3 — have occurred in British nursing and residential homes, known as care homes in the United Kingdom. Care homes are places where elderly or vulnerable people live for short or long periods of time and can receive nursing care.

But that is only a part of the pandemic’s tragic impact inside care homes across the United Kingdom. Deaths attributed to other causes have also risen sharply over the same period — so much so that the homes have 26,000 more deaths than is typical, a concept known as “excess deaths.”

Room Air Purifiers Being Furnished to at Risk Homeowners in Clairton PA

Johnnie Perryman, a 77-year-old Clairton resident recovering from recent major heart surgery, likes to sit on his front porch in the sunshine, but on most days he can’t because of the chronically bad air quality in the industrialized Mon Valley community.

So he’s forced to retreat inside where he can breathe easier due to a whole house air purification system, he credits with saving his life.

“That purification device is the reason I’m still alive,” said Mr. Perryman, a member of Valley Clean Air Now.

The local citizen’s group is part of a nine-member coalition working on a new program to provide free air purifiers to Clairton residents with cardiovascular and respiratory disease who are most at risk during the ongoing COVID-19 pandemic.

People already in the worst of health are the ones dying of COVID. We have to help save as many as we can,” Mr. Perryman said. “We also need to help others avoid developing preexisting conditions.”

The Clairton Home Air Filter Distribution Program will accept applications through Saturday of this week, inform those selected in early June and have the room air purifiers delivered within three or four weeks, by the beginning of July.

The indoor air purifiers are able to reduce levels of fine airborne particulate matter, or soot, as well as other pollutants, from outside air pollution sources like U.S. Steel Corp.’s Clairton Coke Works. That plant is the biggest coke-making facility in the U.S. and among the largest emitters of air pollutants in Allegheny County.

“Residents of Clairton are now at a heightened risk for COVID due to ongoing air pollution issues,” said Dr. Deborah Gentile, medical director for Community Partners in Asthma Care, another coalition member. “This much-needed program will provide the most vulnerable members of the Clairton community some protection against air pollution and its harmful health effects.”

More than 225 households, containing 585 residents, have already applied for the air purifiers, said Myron Arnowitt, Pennsylvania director for Clean Water Action, a member of the coalition.

Of those applicants, 29% have respiratory problems, 26% have cardiovascular disease and 11% have diabetes. Many of the applicant households reported having multiple health problems.

“The response from residents has been overwhelming, with most of the applicants having serious health conditions,” Mr. Arnowitt said. “This program is demonstrating what Clairton residents have been saying for years — that pollution in the area has made them vulnerable to health problems, including COVID-19.”

A $54,000 Heinz Endowments grant provides the program’s seed money, Mr. Arnowitt said, enough to buy air purifiers for 40 to 50 families in the first round. He said the number of air purifiers would be tailored to a family’s home size and needs.

UV is One Option for Dentist Offices

As more businesses reopen, dental practices are considering enhanced measures to clean their facilities and equipment, as well as protect their patients and staff. CNBC provided a good summary of options.

One method involves using ultraviolet light to sanitize the air, surfaces and equipment in dental offices. Disinfecting with UV light products is widely used in hospitals and larger medical facilities, but now small practices are looking into adopting the technology.

Brett Messina, vice president of sales and marketing at Medical Illumination, which makes VidaShield, an air purifier that disinfects using UV light. estimated that 80% to 90% of the company’s new requests were coming from dental offices.

However, before committing to purchasing a product that may cost $2,000 per unit, dentists should understand the advantages and drawbacks of UV technology and know their options. This investment could be particularly costly at a time when practices may be trying to recoup profits after closing operations during the Covid-19 pandemic. 

Dentists in particular may be considering new sanitizing technology in reopening their business because they use procedures where people can easily transmit the virus through droplets in the air, according to Ann Marie Pettis, president-elect of the Association for Professionals in Infection Control and Epidemiology.

She said basic hygiene practices and protective gear should be dentists’ first step in preventing disease transmission.

“Much of what they need to do is what they probably and hopefully were already doing,” Pettis said.

They can also implement new measures such as spacing people 6 feet apart in the waiting room, staggering appointments, practicing “telephone triage,” where patients are asked questions to ensure they are not sick prior to dental treatment and even temperature-screening visitors, according to Pettis. 

The American Dental Association gives similar recommendations in its “Return to Work Interim Guidance Toolkit,” which does not mention UV light decontamination. In response to being asked about UV sanitizing in dental offices, ADA told CNBC it “is researching many strategies to mitigate possible routes of infection.”

“We will continue to evaluate the validity of emerging evidence and research to support any future recommendations supporting the safety and health of the public and profession,” the association said in a statement.

If dentists are interested in purchasing sanitizing equipment in addition to following ADA hygiene practices, UV light products may be a viable option. Pettis said UV sanitizing has been used in large health care facilities for years and is “very effective” in killing germs and bacteria. 

UV light is also particularly useful against coronaviruses, according to Dr. Richard Martinello, an associate professor at Yale School of Medicine and medical director of the Department of Infection Prevention at Yale New Haven Hospital. Martinello is also on the board of the International Ultraviolet Association, which promotes the use of ultraviolet light in sanitizing practices. 

“One good thing about the coronavirus is that it is a very fragile virus,” Martinello said. “What makes it fragile is that it has a layer of lipids, a fatty layer that coats the virus itself, and that layer is very easily disrupted.”

UV light as well as cleaning products like soap and disinfectants can destroy this layer, causing the virus to degrade and die, according to Martinello.

He said his association has seen an increasing interest in UV light applications since the onset of the pandemic. However, just because UV light is effective in decontaminating surfaces does not mean it’s effective for treating the virus in humans, which was an idea President Donald Trump pitched at a press briefing in April. 

Staff members need to take special precautions in order to use this equipment properly, including not being in the room when it is in operation, according to Nicole Greeson, director of the Occupational Hygiene and Safety Division at Duke University and a board officer of the American Industrial Hygiene Association.

“It can cause burns to the skin and to the eyes if the person was not covered with appropriate personal protective equipment, so the best means of protection is to actually have them leave the room so that they wouldn’t have exposure,” Greeson said.

She said this kind of large equipment may not be the best fit for small medical or dental practices, and that other options are available, especially when it comes sanitizing dental tools.

“UV is typically not used for equipment because there are definitely materials for which it’s not compatible,” Greeson said, citing plastic as an example.

Instead, dentists can rely on autoclaves, which are chambers that can come in small sizes and use heat to sterilize tools, according to Greeson.

However, that’s not to say there aren’t UV sterilizing chambers available.

Online dental supplies retailer Treedental has seen an increase in demand for its UV Dental Disinfection Cabinet, according to Jenny Pan, an advertising and marketing planner at the China-based company. The unit has a list price of $145 and a disinfection time of 15 minutes and is supposed to be able to eliminate germs on glass, metal and plastic tools.

The company has been careful in mentioning UV light as being effective against the coronavirus in marketing its products, as research into this is “ongoing,” according to Pan. 

“There is not enough data to say that UV lights can inactivate Covid-19,” she said. 

Instead, when advertising items like masks and gloves, Treedental only mentions products’ ability to “protect” against the coronavirus.

Medical Illumination has taken a similar tactic in promoting its VidaShield UV light air purifier, though Messina said the product has been effective in eliminating different coronaviruses, as well as other germs and bacteria, including MRSA, tuberculosis and influenza. 

“The interest in the VidaShield product has gone up significantly with the pandemic that we’re going through now,” he said. “The air is where a lot of stuff lives.”

In eliminating germs in the air, the product keeps them from settling on surfaces, according to Messina. He said the product is commonly used in hospitals, but that dental offices are becoming interested, too.  

Installed in the ceiling, VidaShield uses fans to draw in air from the surrounding environment and purifies it using UV-C light. It also contains either fluorescent or LED tubing allowing it double as a ceiling light panel.

VidaShield also doesn’t have the same risks as a disinfecting tower does in exposing people to UV light because it is self-contained within the product, according to Messina.

“No UV escapes out of this unit, so it’s safe to use in an occupied space, meaning this can be on 24 hours a day, seven days a week, continually cleaning the air,” he said. 

VidaShield costs anywhere from $1,400 to $2,000 per unit, depending on the model, according to Messina. Comparatively, UV light towers typically used by hospitals and other medical facilities can range in price from $25,000 to $100,000 per unit.

UV Resources, another manufacturer of UV light sanitizing devices, has seen a tenfold increase in business inquiries, including from dental offices and other businesses.

Currently facing back orders, the company has been struggling to meet demand because there are a limited number of manufacturers that make the UV lamps it needs for its products.

UV Resources makes Upper-Room UV-C fixtures, which are mounted on the wall in order to treat air in the environment and costs around $1,000 per unit. Unlike the VidaShield, the UV light is not contained within the unit. Instead, it emits UV light at an upward angle, creating a “kill zone” for microbes that rise in the air near the ceiling, according to Jones. 

UV Resources has faced a rush of inquiries from various businesses consider installing air purifiers in their offices and break rooms.
