BOFA publishes research paper on 3D printing industry emissions

A review into the particulate and gases emitted through 3D printing processes has been published by BOFA International, a provider of fume and dust extraction systems for a wide range of industrial sectors and applications.

The company has consolidated the findings of empirical studies into emissions linked to additive manufacturing processes into a report that provides industry guidance on helping protect both the health of employees and product quality through effective filtration systems.

The study underlines the presence of potentially harmful airborne contaminants in 3D printing processes, including VAT polymerisation (VP) and fused filament fabrication (FFF). These two additive manufacturing processes alone account for approximately 50% of the total components produced in the AM industry.

“The report highlights the importance of installing effective filtration solutions that can help capture and remove any potentially harmful emissions,” said Ross Stoneham, product manager of 3DP & Growth Markets at BOFA International. “This will not only help protect operatives from potentially harmful airborne contaminants but will also ensure that resulting product and the machines remain free from contamination.”

The findings of the report include:

  • The temperature of 3D printer nozzles dramatically influences the volume of particles generated by FFF processes.
  • An increase in 3D printer nozzle temperature decreases the average particle size generated by FFF processes – this means particles can penetrate more easily into the human body, which can potentially impact negatively on health.
  • Any insoluble or low-solubility nanoparticles emitted can pass through human defence mechanisms and locate in the bloodstream, with potential distribution to organs in the body.
  • Gases emitted by FFF printers include volatile organic compounds (VOCs), which can potentially cause operatives conditions such as headaches, eye irritation, skin problems and occupational asthma.

The BOFA industry paper on 3D print emission can be downloaded on BOFA’s website.

SWM announces Q3 results; buoyed by strong performance across filtration portfolio

Schweitzer-Mauduit International, Inc. (SWM) reported earnings results for the three month and nine month periods ended September 30, 2021.

Advanced Materials & Structures segment sales were $260.1 million, up 87%, including the benefit from the Scapa acquisition, while organic sales increased 10%. The organic sales increase was driven by continued rapid growth in transportation sales, specifically automotive paint protection films, as they continued to rebound sharply from COVID-19 related pressures that began early in 2020, and broad strength across our filtration portfolio, particularly water and process filtration products.  Transportation and filtration sales each grew approximately 25%. Construction sales, led by erosion control and turf products, and industrial sales, led by digital printing products, also increased.  Healthcare sales (excluding Scapa) declined as certain products that saw short-term COVID-related demand spikes in prior year quarters, such as facemask materials, faced difficult comparisons.

Engineered Papers segment sales were $123.5 million, down 12%, driven by a 10% volume decrease, unfavorable price/mix of 3%, and a 1% currency benefit.  The volume decline was attributable to lower tobacco-related papers, including LIP, as certain customers resumed more normalized order patterns compared to the third quarter of 2020 when they built inventories to de-risk their supply chains amidst Covid-19 uncertainties. The lower LIP volume was a significant contributor to the negative mix. Continued rapid growth in reduced risk Heat-not-Burn products was a positive offset within the tobacco business. Non-tobacco paper volumes were essentially unchanged.

Unallocated GAAP expenses were $16.9 million, versus $9.7 million in 3Q:20; and included $3.3 million of expenses related to the Scapa acquisition, primarily integration costs.  Adjusted unallocated expenses (which excluded the Scapa acquisition related costs) were $13.6 million, versus $9.6 million.

Consolidated sales were $383.6 million, up 37%, but down 1% excluding the incremental sales from the Scapa acquisition.  Favorable currency movements benefited sales on the business, excluding Scapa, by 1%. GAAP operating profit was $23.0 million, down 38%, and GAAP operating profit margin was 6.0%. Adjusted operating profit was $40.0 million, down 24%, and adjusted operating profit margin was 10.4%, down 850 basis points.  

Third Quarter 2021 Financial Results Summary

  • Continued strong demand in AMS, highlighted by 10% organic sales growth, offset by escalating input cost inflation and supply chain challenges across the business
  • Total sales were $383.6 million, up 37.3%, but down 1% on organic basis
  • GAAP operating profit was $23.0 million, or 6.0% of sales, down $14.0 million; Adjusted operating profit was $40.0 million, or 10.4% of sales, down $12.7 million
  • GAAP EPS was $0.38, down from $0.78; Adjusted EPS was $0.82, down from $1.16; difficult earnings comparison to an exceptionally strong third quarter of 2020
  • Management now expects full year 2021 Adjusted EPS to finish below the $3.75 to $4.05 guidance range provided in May, with fourth quarter Adjusted EPS expected to be down approximately 20% versus prior year quarter (see Management Commentary and Business Outlook sections below for additional detail)

ProPublica publishes report and map showing most toxic air pollution sites in the U.S.

ProPublica published a report showing five years of modeled EPA data, identifying more than 1,000 toxic air pollution hot spots across the United States with an estimated 250,000 people living in them, who may be exposed to levels of excess cancer risk that the EPA deems unacceptable.

Thousands of facilities nationwide that are considered large sources of toxic air pollution submit a report to the government each year on their chemical emissions. Using the reports submitted between 2014 and 2018, ProPublica calculated the estimated excess cancer risk from industrial sources across the country and mapped it out.

The EPA’s threshold for an acceptable level of cancer risk is 1 in 10,000, meaning that of 10,000 people living in an area, there would likely be one additional case of cancer over a lifetime of exposure. But the agency has also said that ideally, Americans’ added level of cancer risk from air pollution should be far lower, 1 in a million.

The ProPublica report includes a map highlighting areas where the additional cancer risk is greater than 1 in 100,000.

Practical Water Solutions starts various pilot projects with NX Filtration’s direct nanofiltration technology in South Africa

Practical Water Solutions (PWS) has partnered with NX filtration to launch various pilot projects to text direct nanofiltration (dNF) membranes for the reuse of industrial wastewater. PWS will deploy NX Filtration’s Mexpert pilot system alongside PWS’ Abrimix technology to conduct pilot projects at industrial clients across South Africa.

“NX Filtration’s dNF technology offers our clients a unique opportunity to reuse their wastewater in a very simple and robust way,” said Rob Cloete, CEO at PWS. “The results of our first pilot projects at Coega Dairy and Summerpride Foods look promising, enabling them to reduce their water footprint by 80%, and 100% respectively. Throughout the coming year, we plan to deploy pilots at industrial customers throughout the country, supporting them in addressing their water challenges.”

PWS is offering a WaaS solution based on the Abrimix Suspended Solid Flotation (SSF) technology and NX Filtration’s dNF technology to enable potable water recovery from wastewater in industrial processes. The first two pilot projects have been conducted at the Dairy Group’s Coega Dairy and Summerpride Foods.

“Industrial wastewater reuse is one of the sweet spots of our dNF technology,” said Johann Lombaard, Sales Manager at NX Filtration. “Building on our experience at various European, North American and Asian industrial clients, we are happy that we can now also roll this out in South Africa. With our dNF membranes we can remove microplastics, pesticides, pharmaceuticals and colour from wastewater in one single step, while recovering certain raw materials that can be recycled in industrial processes. In addition, we offer strong sustainability benefits to our customers, as our technology avoids the use of pre-treatment chemicals and requires significantly less energy than conventional methods.”

In 2018, Cape Town’s “Day Zero” became the focus for South Africa’s water crisis. However, the entire country is impacted by high demand and inadequate supply of water. As a result, more stringent regulations are being implemented. For example, in the Gqeberha (formerly Port Elizabeth) area, industries are now being required to reduce water consumption by a minimum of 20%.
