Sustainable packaging takes centre stage at Westfalia Fruit’ in France

Westfalia Fruit’s business in France, has launched a new range of environmentally and consumer friendly packaging for avocados that dramatically reduces and replaces the use of plastic, eliminating altogether the use of black plastic which is difficult to recycle, whilst successfully maintaining fruit quality. These industry leading initiatives, were stringently researched and developed in advance of a new law banning plastic packaging on most fruit and vegetables, which came into effect in France from New Year’s Day 2022. Cucumbers, lemons and oranges are among the 30 varieties banned from being wrapped in plastic according to the new law.

These sustainable packaging alternative solutions include options with no plastic, or a significant reduction in plastic, reflecting Westfalia’s industry leadership in environmental sustainability including waste and carbon emission reductions.

Zero plastic options include a cardboard tray with a paper label or a paper band, that are fully compostable. Both are made with Forest Stewardship Council materials, guaranteeing that the cardboard used has been sourced from sustainably managed forests that consider people, wildlife and the environment in the long term. The FSC is the only timber certification scheme endorsed by the conservation organisation WWF. A heat seal film option includes recyclable plastic which contains a QR code on the packaging directing consumers to details of where they can recycle their plastic rubbish. A paper lid is also in development for this packaging.

Additional solutions include an FSC certified string bag and zero packaging natural laser marking on the skin of the avocado itself permitting logo & messaging placement.

“We have worked hard to remove plastic from our packaging to contribute to solving the plastic waste challenge and to lower our carbon footprint. We are delighted to take a proactive approach in implementing industry leading initiatives, enabling compliance to respective laws whilst offering a host of solutions for our customers and consumers,” said Johnathan Sutton, Group Safety & Environmental Executive at Westfalia Fruit.

The packaging initiatives have been introduced and adopted as solutions by a wide range of retailers in France.

World’s first LED lights developed from rice husks

World’s first LED lights developed from rice husks

Milling rice to separate the grain from the husks produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot (QD) LED light. Their new method transforms agricultural waste into state-of-the-art light-emitting diodes in a low-cost, environmentally friendly way.

“Since typical QDs often involve toxic material, such as cadmium, lead, or other heavy metals, environmental concerns have been frequently deliberated when using nanomaterials. Our proposed process and fabrication method for QDs minimizes these concerns,” said Ken-ichi Saitow, lead study author and a professor of chemistry at Hiroshima University.

Since porous silicon (Si) was discovered in the 1950s, scientists have explored its uses in applications in lithium-ion batteries, luminescent materials, biomedical sensors, and drug delivery systems. Non-toxic and found abundantly in nature, Si has photoluminescence properties, stemming from its microscopic (quantum-sized) dot structures that serve as semiconductors.

Aware of the environmental concerns surrounding the current quantum dots, the researchers set out to find a new method for fabricating quantum dots that has a positive environmental impact. Waste rice husks, it turns out, are an excellent source of high-purity silica (SiO2) and value-added Si powder.

The team used a combination of milling, heat treatments, and chemical etching to process the rice husk silica: First, they milled rice husks and extracted silica (SiO2) powders by burning off organic compounds of milled rice husks. Second, they heated the resulting silica powder in an electric furnace to obtain Si powders via a reduction reaction. Third, the product was a purified Si powder that was further reduced to 3 nanometer in size by chemical etching. Finally, its surface was chemically functionalized for high chemical stability and high dispersivity in solvent, with 3 nm crystalline particles to produce the SiQDs that luminesce in the orange-red range with high luminescence efficiency of over 20%.

“This is the first research to develop an LED from waste rice husks,” said Saitow, adding that the non-toxic quality of silicon makes them an attractive alternative to current semiconducting quantum dots available today.

“The present method becomes a noble method for developing environmentally friendly quantum dot LEDs from natural products,” he said.

The LEDs were assembled as a series of material layers. An indium-tin-oxide (ITO) glass substrate was the LED anode; it is a good conductor of electricity while sufficiently transparent for light emission. Additional layers were spin-coated onto the ITO glass, including the layer of SiQDs. The material was capped with an aluminum film cathode.

The chemical synthesis method the team developed has allowed them to evaluate the optical and optoelectrical properties of the SiQD light-emitting diode, including the structures, synthesis yields, and properties of the SiO2 and Si powders and SiQDs.

“By synthesizing high-yield SiQDs from rich husks and dispersing them in organic solvents, it is possible that one day these processes could be implemented on a large scale, like other high-yield chemical processes,” Saitow said.

The team’s next steps include developing higher efficiency luminescence in the SiQDs and the LEDs. They will also explore the possibility of producing SiQD LEDs other than the orange-red color they have just created. Looking ahead, the scientists suggest that the method they have developed could be applied to other plants, such as sugar cane bamboo, wheat, barley, or grasses, that contain SiO2. These natural products and their wastes might hold the potential for being transformed into non-toxic optoelectronic devices. Ultimately, the scientists would like to see commercialization of this eco-friendly approach to creating luminescent devices from rice husk waste.

Light, oxygen turn waste plastics into useful benzoic acid

Light, oxygen turn waste plastics into useful benzoic acid

Styrofoam egg cartons, hard plastic compact disc cases, red drinking cups and many other common products are composed of polystyrene, a type of plastic that makes up a third of landfill waste worldwide.

“In terms of plastic production and end-of-life waste streams, we are on the road to an unsustainable future,” said Erin Stache, assistant professor of chemistry and chemical biology in the College of Arts and Sciences.

But there’s good news: Stache has discovered a new path for polystyrene waste that includes being upcycled into benzoic acid, a chemical with wide commercial demand, through a mild process that uses light, an oxygen-rich environment and an abundant iron-based catalyst. The reaction can even take place in a sunny window.

In line with her lab’s mission to tackle environmental concerns through interesting chemistry, the new process is mild, climate-friendly and scalable to commercial waste streams, Stache said. It efficiently produces benzoic acid, a product stocked in undergraduate and high school chemistry labs and also used in fragrances, food preservatives, and other ubiquitous products.

Moreover, the process is tolerant of additives inherent in a flow of consumer waste, including dirt, dyes and other types of plastics.

Polystyrene (PS) plastics vary widely in form, use and texture – from light, airy Styrofoam to hard CD cases, and many forms in between. All these products are similar in chemical composition, Stache said.

“The difference is in how they are processed,” she said. “Polystyrene foam, or Styrofoam, is filled with air, like a meringue, whereas a hard plastic CD case is solid polystyrene.”

At the molecular level, polymers (plastics) are composed of hundreds of small molecules called monomers assembled into long molecular chains through complicated processes, Stache said. Breaking down a polymer can be similarly intricate.

The researchers found that optimized conditions require a PS sample in acetone exposed to LED light in an oxygen-rich environment, using an iron chloride catalyst for 20 hours. In the optimized process, PS broke down to 23% benzoic acid. Other products included smaller plastic molecules that can be repurposed in other ways.

Last summer, Stache’s lab ran some degradation experiments in a sunny window; in a place with strong year-round sunlight, the reaction could be done outdoors.

“The advantage of using light is you can get exquisite control over the chemical process based on some of the catalysts we’ve developed to harness the white light. If we can use sunlight to drive the process, that’s a win-win,” Stache said, noting that many existing polymer recycling require heating a polymer for melting and processing, which usually requires fossil fuel.

To test the tolerance of the process to other materials mixed with the PS plastic, the researchers used several products, ranging from packaging materials to coffee cup lids.

They found that three items – a white coffee cup lid, Styrofoam and a clear lid – degraded efficiently. A black coffee cup lid degraded less efficiently, possibly because the black dyes inhibit light penetration, Stache said.

“These results signify that our system could efficiently break down commercial samples of PS, even with additional composite and insoluble material,” she said.

To demonstrate scalability and potential commercial application, the researchers created a setup with two syringe pumps and two LED lamps in a 3D-printed photoreactor. The efficiency of the breakdown process at the large scale was similar to that in small batches.

“If we can make the process even more efficient, we can think about how to commercialize it and use it to address waste streams,” Stache said.

Mondi and Thimonnier team up to make recyclable packaging for liquid soap refills

  • Mondi and Thimonnier launch a new recyclable mono-material berlingot sachet for liquid soap refills
  • The innovative new packaging reduces plastic usage by more than 75% compared to rigid plastic bottles
  • The solution is designed to replace the current industry standard of non-recyclable plastic

Mondi, a global leader in packaging and paper, has joined forces with French machine supplier Thimonnier to develop a recyclable packaging that reduces plastic waste.

The companies have created a new packaging for liquid refills that is designed so that it can be entirely emptied. The berlingot sachet is made from a recyclable mono-material, coextruded polyethylene (PE). It not only weighs less but also reduces plastic usage by more than 75% compared to rigid plastic bottles. The refill solution can replace the current industry standard of multilayer PVC refill containers, which are effectively not recyclable.

The unusual shape of the sachet is eye catching and differentiated. The durable and leak-proof solution allows consumers to smell the product inside, a particularly useful feature for the liquid soaps it is designed to protect. The lightweight material also makes it more convenient for customers, especially those who are buying in-store.

“Our goal working with Mondi was to find a packaging alternative with low environmental impact and good runnability. We are pleased to have found a solution that achieves both”, explained Eric Duhoo, General Manager at Thimonnier.

For Mondi, the solution was further demonstration of the benefits of partnership and its importance to achieving a truly circular economy. “Our Mondi Action Plan 2030 (MAP2030) sustainability framework sets ambitious goals to tackle global issues across the value chain: creating circular-driven packaging and paper solutions that are made by empowered people taking action on climate. We are proud and excited to partner with customers like Thimonnier to achieve our goal of keeping materials in circulation and making a real difference”, said Olivier Werbrouck, Regional Sales Consumer Flexibles, Mondi.

MAP2030 includes a target to make 100% of Mondi’s products reusable, recyclable or compostable by 2025. The sustainability plan also includes other commitments and targets in relation to circular driven solutions, people and climate – all of which are underpinned by a set of responsible business practices. Mondi has a long history of working with industry leaders to design packaging that is both effective and sustainable by design. The berlingot refill packaging was launched during the 25th edition of the CFIA in Rennes, France from 8 March to 10 March.
