Advocates are particularly concerned over the use by datacenters of PFAS gas, or f-gas, which can be potent greenhouse gases, and may mean datacenters’ climate impact is worse than previously thought. Other f-gases turn into a type of dangerous compound that is rapidly accumulating across the globe. Two kinds of cooling systems are used to prevent the semiconductors and other electronic equipment stored in datacenters from overheating. Water cooling systems require huge volumes of water, and chemicals like nitrates, disinfectants, azoles and other compounds are potentially added and discharged in the environment. Many centers are now switching to a “two phase” system that uses f-gas as a refrigerant coolant that is run through copper tubing. In this scenario, f-gas is not intentionally released during use, though there may be leaks, and it must be disposed of at the end of its life.

The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer. Previously, researchers proposed using these sticky natural polymers to clean up water. Now, they report in ACS Omega that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics in ocean water, freshwater and groundwater.

As artificial intelligence (AI) and cloud computing continue to expand, the demand for data processing—and the heat it generates—is skyrocketing. Currently, cooling accounts for up to 40% of a data center’s total energy use. If trends continue, global energy use for cooling could more than double by 2030. Engineers at the University of California San Diego have developed a new cooling technology that could significantly improve the energy efficiency of data centers and high-powered electronics. The technology features a specially engineered fiber membrane that passively removes heat through evaporation. It offers a promising alternative to traditional cooling systems like fans, heat sinks and liquid pumps. It could also reduce the water use associated with many current cooling systems.

The advance is detailed in a paper published on June 13 in the journal Joule.

The Office of Electricity’s (OE’s) Microgrid Program recently concluded a scoping study of the campus microgrid at the University of Illinois Urbana-Champaign with a focus on integrating a Small Modular Reactor (SMR) into the generation mix. SMRs are advanced nuclear reactors that have a power capacity of up to 300 MW(e) per unit (about one-third the size of traditional nuclear power reactors). The nuclear power industry is rapidly innovating to meet the energy demands of a decarbonizing world.  Advanced technologies, such as SMRs, can be deployed as electricity producers on the grid or in tightly integrated energy systems, such as campus microgrids, to provide reliable, dispatchable carbon-free power.

'Pacifiers can release bisphenol A, a chemical linked to hormone disruption and developmental problems, with the highest levels found in one marketed as "BPA-free," a new study shows. The research, published Jan. 24 in Environmental Science and Pollution Research, raises questions about hidden chemical exposure during infancy and how baby products are regulated and labeled. It is among the first to quantify how much BPA can leach from pacifiers and estimate how much infants and toddlers, whose bodies and hormone systems are still developing, may absorb during everyday use.'

In a paper published in the Journal of Hazardous Materials, Sarah Sajedi and colleagues from Concordia University look at the science around the health risks posed by single-use plastic water bottles. They are serious, Sajedi says, and seriously understudied. In her review of over 140 scientific articles, Sajedi writes that individuals on average ingest between 39,000 and 52,000 microplastic particles per year, and bottled water users consume 90,000 more particles than tap water consumers. Once inside the body, these small plastics can cross biological boundaries, enter the bloodstream and reach vital organs. This can lead to chronic inflammation, oxidative stress on cells, hormonal disruption, impaired reproduction, neurological damage and various kinds of cancer. However, the long-term effects remain poorly understood due to a lack of widespread testing and standardized methods of measurement and detection.

Using a high-tech instrument to measure how aerosol particles form and grow in the atmosphere, researchers at the University of Colorado Boulder stumbled upon something unexpected: the first-ever airborne measurements of Medium Chain Chlorinated Paraffins (MCCPs), a kind of toxic organic pollutant, in the Western Hemisphere. Their results published today in ACS Environmental Au. MCCPs are currently under consideration for regulation by the Stockholm Convention, a global treaty to protect human health from long-standing and widespread chemicals. While the toxic pollutants have been measured in Antarctica and Asia, researchers haven’t been sure how to document them in the Western Hemisphere’s atmosphere until now. MCCPs are used in fluids for metal working and in the construction of PVC and textiles. They are often found in wastewater and as a result, can end up in biosolid fertilizer, also called sewage sludge, which is created when liquid is removed from wastewater in a treatment plant. In Oklahoma, researchers suspect the MCCPs they identified came from biosolid fertilizer in the fields near where they set up their instrument.

Giving a second life to construction materials after demolition, engineers at the University of São Paulo and Princeton have developed an approach for recycling cement waste into a sustainable, low-carbon alternative that is comparable in performance to the industry standard. In addition to lowering the carbon intensity of the cement and concrete industry, the process could enable new uses for construction and demolition waste, of which concrete is a significant component. In 2018 in the United States, the total amount of construction and demolition waste was more than twice that of household waste. In their paper, published in ACS Sustainable Chemistry & Engineering, the researchers demonstrated that mixtures containing up to 80% of this recycled cement were just as strong as conventional Portland cement by itself while generating a fraction of the carbon emissions.

While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer (1/50th the thickness of an average human hair), are far more reactive, far more mobile and vastly more capable of crossing biological membranes. Yet, because they are so tiny and so mobile, researchers don't yet have an accurate understanding of just how toxic these particles are. The first step to understanding the toxicology of nanoplastics is to build a reliable, efficient and flexible tool that can not only quantify their concentration in a given sample, but also analyze which specific plastics that sample contains.

An international team of scientists led by the University of Massachusetts Amherst recently announced in Nature Water the development of a new tool, known as the OM-SERS setup, which can do all of these things and can furthermore be used to detect particular nanoplastic concentrations and polymer types in solid samples, such as soils, body tissues and plants.

Household hazardous waste (HHW) is showing up on states’ and local jurisdictions’ radar, fueled by safety concerns and the exorbitant cost to manage these materials. As batteries, vapes, compressed gas cylinders, and certain other products flood waste and recycling streams, they spark fires and injure waste workers while leaving governments to shoulder most of the cleanup costs. In response, a few jurisdictions are looking at extended producer responsibility (EPR) laws, requiring producers to take responsibility for dealing with these materials at the end of life.

As global plastic production has ballooned, small fragments of plastic have infiltrated rivers, sea ice, and even our brains. When the minuscule fibers and shards seep into soils, they change how the soil interacts with water, according to a new study. The study, published in Vadose Zone Journal, measured water retention and conductivity in soils from three regions of Germany with and without four different microplastics. The researchers found that a plastic concentration of just 0.4% by mass can change how quickly water flows through soil, depending on both the type of plastic and the type of soil. The altered hydraulic properties likely result from the hydrophobic nature of plastic and the microplastic particles changing the arrangement of individual soil granules, the authors said.

A major discovery by an interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has found a safer and more sustainable approach to extract and recover gold from ore and electronic waste. The glistening gold-extraction technique, unveiled in the leading global journal Nature Sustainability, promises to reduce levels of toxic waste from mining and shows that high purity gold can be recovered from recycling valuable components in printed circuit boards in discarded computers. 

The new process uses a low-cost and benign compound to extract the gold. This reagent (trichloroisocyanuric acid) is widely used in water sanitation and disinfection. When activated by salt water, the reagent can dissolve gold. Next, the gold can be selectively bound to a novel sulfur-rich polymer developed by the Flinders team. The selectivity of the polymer allows gold recovery even in highly complex mixtures. The gold can then be recovered by triggering the polymer to “un-make” itself and convert back to monomer. This allows the gold to be recovered and the polymer to be recycled and reused.

Harnessing moisture from air, Northwestern University chemists have developed a simple new method for breaking down plastic waste. The non-toxic, environmentally friendly, solvent-free process first uses an inexpensive catalyst to break apart the bonds in polyethylene terephthalate (PET), the most common plastic in the polyester family. Then, the researchers merely expose the broken pieces to ambient air. Leveraging the trace amounts of moisture in air, the broken-down PET is converted into monomers — the crucial building blocks for plastics. From there, the researchers envision the monomers could be recycled into new PET products or other, more valuable materials. Safer, cleaner, cheaper and more sustainable than current plastic recycling methods, the new technique, published in the journal Green Chemistry, offers a promising path toward creating a circular economy for plastics.
