'In a sustainable twist to the saying"When life gives you lemons, make lemonade," researchers in Hawaii are developing a method to convert discarded fishing nets and plastic trash into asphalt roads. Their early tests show that incorporating recycled plastic into asphalt is technically viable and bears minimal risk of shedding microplastics that could end up in the oceans. The team from the Center for Marine Debris Research at Hawai'i Pacific University presented their innovative solution to the island's plastic waste problem at the American Chemical Society Spring 2026 conference.'

"US researchers at Oak Ridge National Laboratory (ORNL) have found a new way to turn the world’s most common plastic waste into gasoline and diesel fuels. Polyethylene is a common polymer used in the manufacturing of grocery bags, kitchen cutting boards, and other consumer goods. Through a specialized molten salt treatment, the long polymer chains in polyethylene are broken down into fuel-grade molecules. Currently, other known methods use high heat to break down plastic, but this new technique accomplishes the same at temperatures around 200°C (392°F). It makes the entire conversion process much cheaper and less energy-intensive."

"Textile waste continues to be one of the most pressing sustainability challenges in our industry, but new collaborations are constantly emerging to combat the issue and make responsible disposal easier for consumers. As we enter Earth Month, WM, UNIQLO, and Piece of Cake Moving & Storage are expanding the UNTrash It Program beyond New York City into Los Angeles and Dallas. This move will build on a pilot program that has diverted more than 7,000 pounds of clothing from landfills and into reuse and recycling streams. To get more insight into this expansion and initiative, Waste360 caught up with Tom Carpenter, senior director of circulatory solutions at WM, and Jean Shein, global director of sustainability at UNIQLO. The two share how the partnership is working to scale textile recovery efforts and reshape how consumers think about clothing disposal."

'Scientists have created a “sustainable, highly efficient” method to “upcycle plastics to value-added acetic acid,” which is the main component of vinegar, said a study published in the journal Advanced Energy Materials. The process is a “bio-inspired cascade photocatalysis using iron atoms embedded in carbon nitride,” said a release about the study. It is similar to “how certain types of fungi break down organic matter using enzymes.”'

In February 2026 Malaysia announced 'an immediate and full ban on the importation of electronic waste, as the government vowed the country would not be a “dumping ground” for the world’s waste. The Malaysian Anti-Corruption Commission said in a statement late Wednesday that all electronic waste, commonly known as e-waste, would be reclassified under the “absolute prohibition” category effective immediately. This removes the discretionary power previously given to the Department of Environment to grant exemptions for importation of certain e-waste.'

'Texas A&M AgriLife Research scientists have developed a patented breakthrough system that marks a major step forward in insect biomanufacturing, waste reduction and sustainable protein production. The new "Black Soldier Fly Billet" was developed in the lab of Jeffery Tomberlin, Ph.D., a Texas A&M AgriLife Research Fellow, professor in the Texas A&M Department of Entomology and director of the Center for Insect Biomanufacturing and Innovation. It represents the first reliable method for long-term, room-temperature storage of young black soldier fly larvae...Each billet is a pint-sized container engineered with layers of fermented feed, newborn larvae and a dry food "blanket," sealed with a breathable lid that maintains consistent moisture and temperature. The system preserves larval viability far beyond the two-to-four-day window typical under conventional rearing methods. Once opened and emptied onto organic waste, Tomberlin said each unit can generate up to more than 3 pounds of harvestable larvae in as little as seven to 10 days.'

'Switching to a circular electric vehicle (EV) battery economy is essential to meet growing demand and avoid a critical bottleneck in the supply of key minerals, according to a new analysis.

The report by the Ellen MacArthur Foundation warns a bottleneck could threaten higher and volatile prices, which in turn could lead to a slower uptake of such vehicles.

It argues only a practical, system-wide circular economy approach can keep pace with market appetite, build resilience in the supply chains, and deliver better value.'

'German biotechnology company Bioweg, in partnership with Technische Universität Berlin (TU Berlin), has secured 1.5 million euros, or $1.76 million, from SPRIND, Germany’s Federal Agency for Disruptive Innovation, as part of the Tech Metal Transformation Challenge. The funding will support the development of Bioweg’s platform technology for water-based rare earth element (REE) recovery...The platform technology combines Bioweg's expertise in bioacid production from waste streams for bioleaching with TU Berlin's peptide-based separation technology using column systems. The process operates in water at ambient temperature, applying green-chemistry bioleaching without the use of solvents or high heat, according to a news release Bioweg issues about the grant award. The bio-based acids are generated as a secondary output of Bioweg's fermentation platform, requiring no additional downstream processing, resulting in a low-energy process with a reduced overall CO₂ footprint.'

Yuwei Gu, an assistant professor in the Department of Chemistry and Chemical Biology in the Rutgers School of Arts and Sciences, was hiking through Bear Mountain State Park in New York when inspiration struck.  If nature can build polymers that serve their purpose and then disappear, Gu reasoned, perhaps human-made plastics could be made to do the same. Gu already knew that natural polymers contain tiny helper groups built into their structure that make chemical bonds easier to break when the time is right.  In a study published in Nature Chemistry, Gu and a team of Rutgers scientists have shown that by borrowing this principle from nature, they can create plastics that break down under everyday conditions without heat or harsh chemicals.

A new report by Ocean Conservancy assessed how states are doing against six benchmarks and scored them based on a five-point scale. The average score was a meager 1.5. Benchmarks included the presence or absence of policies in four areas: 1) single-use plastics, 2) microplastics, 3) reduce and reuse, and 4) producer accountability, as well as access to recycling and recycling rates. Ocean Conservancy went on to recommend what it considers the best of existing policies for improvement, and red-flagged policies it believes are thwarting progress.

Researchers from Oregon State and the Rural Development Administration in South Korea have made a key advance in turning spent coffee grounds into food packaging materials that can extend the shelf life of products. Their findings were published in the Journal of Food Science.

An estimated 60 million tons of spent coffee grounds are generated worldwide annually. Most end up in landfills and release methane, a potent greenhouse gas. That has led researchers to study other uses for coffee grounds, such as incorporating them into biofuels, cosmetics, catalysts and composite materials, including concrete, and now food packaging materials. The researchers believe coffee grounds could be used to make different food packages, including sheets between sliced cheese, pads underneath fresh meat and pads in clamshell containers used to package strawberries.

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.

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.

We’ve all felt the sting of guilt when fruit and vegetables go bad before we could eat them. Now, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have shown they can extend the shelf life of harvested plants by injecting them with melatonin using biodegradable microneedles. Refrigeration is the most common way to preserve foods, but it requires energy and infrastructure that many regions of the world can’t afford or lack access to. The researchers believe their system could offer an alternative or complement to refrigeration. For the open access version of their paper, see https://hdl.handle.net/1721.1/159257.
