Solvay and P&G Join Forces in Industry- Leading Effort to Double the Global Supply of Sustainable Guar Farming in India

The partnership with P&G Beauty in the Sustainable Guar Initiative will accelerate sustainable growth of guar at scale, empower more women farmers, and further improve the livelihoods of smallholder guar bean farmers in India

Solvay, a leading global supplier of naturally-derived polymers for beauty care formulations, has announced that P&G Beauty has joined its Sustainable Guar Initiative (SGI), an industry-leading program launched in 2015, aimed at developing sustainable guar production at scale within the Bikaner desert district of Rajasthan, India. The district is one of the country’s largest guar producers and supplies Solvay with guar as a natural and renewable resource for Jaguar® used in hair and body care formulations.

“I am delighted to welcome P&G Beauty to the Sustainable Guar Initiative,” said Solvay CEO Ilham Kadri. “Through this fantastic partnership we will be able to significantly increase our impact and I’m particularly proud that together we will ramp up our efforts to empower farmers, especially women farmers. This is a win for farmers, customers and consumers.”

With the partnership of P&G Beauty, one of the market leaders in the beauty category, the SGI program will nearly double its reach in the region. It will significantly expand its efforts to equip guar farmers, especially women farmers, with the tools and knowledge in good agricultural practices1 that promote continuous improvement on key outcomes like higher-yield production and crop productivity, improved financial stability, and better living and working conditions.

P&G Beauty’s partnership will add 5,250 new farmers to the program, bringing the total reach of the SGI program to just over 11,000 famers. This includes doubling the reach and scale of the program with women, by training, supporting, and empowering 1,800 additional women as farmers, entrepreneurs, workers, and members of farming households.

In addition, P&G Beauty will enable the SGI program to double the number of women trained (nearly 900 in total) in the adoption of household hygienic practices as well as in the building of kitchen gardens, which will give women and their families the ability to improve their food security, household nutritional diversity and their livelihoods. The P&G Beauty project will also include the construction of a new johad (a local community owned pond), designed to improve the capture and percolation of rainwater for home use, animal hydration as well as the establishment of a community plantation unit.

“We are proud to join forces with Solvay to significantly expand the positive impact of the Sustainable Guar Initiative and to accelerate the growth of this important program,” says Alex Keith, CEO, P&G Beauty. “Working in partnership with Solvay and TechnoServe India is enabling our continued commitment to Responsible Beauty and to being a positive force for beauty in the world. We hope this program inspires others to invest in the sustainable growth of guar, empowerment of women farmers and improving the lives and livelihoods of farming communities in India.”

“As a founding member of the Sustainable Guar Initiative, our aim is to conceive, demonstrate, and refine scalable actions for an inclusive, sustainable growth of the Guar production system in India,” explains Punit Gupta, Country Director, TechnoServe India. “We are delighted to welcome P&G Beauty on this important effort as they move to become a buyer and funder of sustainable guar. Being one of the market leaders in the beauty category, P&G Beauty’s partnership is a significant step in support of TechnoServe’s work to promote sustainable livelihoods among smallholder guar bean farmers in India.”

About the Sustainable Guar Initiative
The SGI program was launched by Solvay in 2015 and empowers guar farmers with tools and knowledge for cultivating their crops. The program includes training in climate-smart agricultural practices to improve and stabilize guar yield and increase soil fertility. It also aims to enhance the Bikaner region’s climate preparedness and resilience. From 2015 to the end of 2020, the initiative led to a 125 percent increase in guar yields and an increase in revenues to guar farmers of 143 percent.

Solvay is further enhancing social impact by leveraging blockchain and building a digital platform, with two partners TechnoServe and BanQu, tracing the transaction from farm to shampoo. So far, this platform is available for 2000 farmers to record their transactions of guar volumes and related payments.

With P&G Beauty’s partnership, the program will double its impact and scale, strengthening its action amongst areas such as, but not limited to, ensuring that local children are not missing school, that communities have access to clean and safe drinking water, that women and families are trained on best practices for health and hygiene, that practices are established to monitor the survival of plantations, and that a local Farmer Producer Organization is created to ensure economic stability of the farmers and their families.

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

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.
