Forgive the elevator pitch but the types of projects which really excite me have the potential for real world positive outcomes for people, community and environment.

Particularly those tackling the challenges of climate change and sustainability.

If you are looking for someone for your sustainability project, I have experience working on projects for WRAP and the Swedish EPA andycarolan.com

Far more plastic in oceans than thought:

“A new study published Wednesday in the journal Nature estimates that the North Atlantic Ocean alone contains 27 million metric tons of nanoplastic...

That figure is 10 times higher than previous estimates of plastic pollution of all sizes across all the world’s oceans, according to the study’s authors.”

#Okra and #Fenugreek Extracts Safely Remove #Microplastics From Water in New Texas Research

May 10, 2025

"The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer.

"Texas researchers proposed in 2022 using these sticky #NaturalPolymers to clean up water. Now, they’ve found that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics from #ocean water, #freshwater, and #groundwater.

"With funding from the U.S. Department of Energy, Rajani Srinivasan and colleagues at Tarleton State University found that the plant-based polymers from okra, fenugreek, and #tamarind stick to microplastics, clumping together and sinking for easy separation from water.

"In this next stage of the research, they have optimized the process for okra and fenugreek extracts and tested results in a variety of types of water.

"To extract the sticky plant polymers, the team soaked sliced okra pods and blended fenugreek seeds in separate containers of water overnight. Then, researchers removed the dissolved extracts from each solution and dried them into powders.

"Analyses published in the American Chemical Society journal showed that the powdered extracts contained #polysaccharides, which are natural polymers. Initial tests in pure water spiked with microplastics showed that:

- One gram of either powder in a quart (one liter) of water trapped microplastics the most effectively.
- Dried okra and fenugreek extracts removed 67% and 93%, respectively, of the plastic in an hour.
- A mixture of equal parts okra and fenugreek powder reached maximum removal efficiency (70%) within 30 minutes.
- The natural polymers performed significantly better than the synthetic, commercially available polyacrylamide polymer used in #wastewater treatment.

"Then the researchers tested the plant extracts on real microplastic-polluted water. They collected samples from waterbodies around Texas and brought them to the lab. The plant extract removal efficiency changed depending on the original water source.

"Okra worked best in ocean water (80%), fenugreek in groundwater (80-90%), and the 1:1 combination of okra and fenugreek in freshwater (77%).

"The researchers hypothesize that the natural polymers had different efficiencies because each water sample had different types, sizes and shapes of microplastics.

"Polyacrylamide, which is currently used to remove contaminants during wastewater treatment, has low toxicity, but its precursor #acrylamide is considered #toxic. Okra and fenugreek extracts could serve as #biodegradable and #nontoxic alternatives.

" 'Utilizing these plant-based extracts in water treatment will remove microplastics and other pollutants without introducing additional toxic substances to the treated water,' said Srinivasan in a media release, 'thus reducing long-term health risks to the population [and the environment].

"She had previously studied the use of food-grade plant extracts as non-toxic flocculants to remove textile-based pollutants from wastewater and thought, ‘Why not try microplastics?’"

Remarkable story from @mongabay about the Moken people of Thailand, sea nomads pushed to adapt onshore due to ecological damage and politics:

“When we were children, the boat was like our home.

We kept traveling around.

By the time we return to this island, the resources we collected earlier would have replenished themselves.”
