On December 5, 2019, the National Toxicology Program (NTP) announced that the NTP Technical Report on the Toxicity Studies of 1020 Long Multiwalled Carbon Nanotubes Administered by Inhalation to Sprague Dawley (Hsd:Sprague Dawley® SD®) Rats and B6C3F1/N Mice is now available.  In 2003, the Rice University Center for Biological and Environmental Nanotechnology nominated nanoscale materials as a class of substances for toxicological evaluation.  The recommended...

By Lynn L. Bergeson and Ligia Duarte Botelho, M.A. First published last week, on November 25, 2019, the article titled “Consolidated Production of Coniferol and Other High-Value Aromatic Alcohols Directly from Lignocellulosic Biomass” has gained media attention across the globe. Given the finite geological oil reserves, the competition to identify alternative biobased and biorefinery processes continues to grow. According to the article, the aim in identifying such products is not...

By Lynn L. Bergeson On December 3, 2019, Governor of Iowa, Kim Reynolds, signed an Executive Order that requires all new contracts for the purchase of state vehicles with diesel engines to have written support from the manufacturer to use B20 biodiesel (a mix of 20 percent biodiesel and 80 percent petroleum-based diesel) or more. The Iowa Department of Transportation (DOT) started using biodiesel blends in 1994. B20 is used for most of the year already, in most equipment with a diesel engine,...

By Lynn L. Bergeson From December 11 through 12, 2019, DOE’s Office of Bioenergy Technologies Office will host a workshop titled “Plastics for a Circular Economy” in Denver, Colorado. The workshop will include discussions on technology solutions to address plastic waste and focus on the development of new recycling and degradation strategies. The objective of the workshop will be to identify early-stage applied research problems in the aforementioned area that need to be...

On November 25, 2019, the European Union (EU) Observatory for Nanomaterials (EUON) announced the publication of a study published in Frontiers in Pharmacology entitled “Unpredictable Nanoparticle Retention in Commonly Used Plastic Syringes Introduces Dosage Uncertainties That May Compromise the Accuracy of Nanomedicine and Nanotoxicology Studies.”  The researchers in the study radiolabeled a variety of different nanoparticles, loaded suspensions of particles into different plastic...

On December 4, 2019, the U.S. Environmental Protection Agency (EPA) published an advance notice of proposed rulemaking (ANPRM) soliciting information as EPA considers a future rulemaking to add certain per- and polyfluoroalkyl substances (PFAS) to the list of toxic chemicals subject to reporting under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) and Section 6607 of the Pollution Prevention Act (PPA) (more commonly known as the Toxics Release Inventory...

There is less than one month before the effective date of the online requirements set forth in California’s Cleaning Product Right to Know Act of 2017 (S.B. 258). S.B. 258 sets forth new requirements on manufacturers of “designated products” to disclose certain chemical ingredients on the manufacturer’s website and product label. The online ingredient disclosure requirements set forth under California’s law are applicable to designated products sold in California as of January 1,...

The European Chemicals Agency (ECHA) announced on December 3, 2019, that it has developed a new Appendix for nanoforms applicable to the Guidance on Registration and Substance Identification.  According to ECHA, it aligns ECHA’s guidance with the amended annexes of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation that will apply to nanomaterials and enter into force on January 1, 2020.  The new guidance document explains the term nanoform,...

The U.S. Environmental Protection Agency (EPA) announced on December 2, 2019, that it granted the first two manufacturer requests for risk evaluations for diisodecyl phthalate (DIDP) and diisononyl phthalate (DINP), two chemicals used in plastic production.  EPA states that if the requests are not withdrawn within 30 days, both DIDP and DINP will enter the risk evaluation process under the Toxic Substances Control Act (TSCA).  Manufacturer-requested risk evaluations are conducted in the same...

The European Commission’s Joint Research Center (JRC) recently published a white paper entitled Anticipation of regulatory needs for nanotechnology-enabled health products.  The white paper notes that at this time, “no specific regulatory framework exists for nanotechnology-enabled health products but the current regulatory practice requires additional guidance in order to fully cover the particularities of such products.”  The white paper identifies the following major...
