A … Mealworms fed a steady diet of HBCD-laden polystyrene were as healthy as those eating a normal diet.
"Mealworms safely consume toxic additive-containing plastic."
In 2015 alone, nearly 25 million metric tons of these chemicals were added to plastics, according to various studies. part may be reproduced without the written permission.
Your email address is used The same was true of shrimp fed a steady diet of the HBCD-ingesting mealworms and their counterparts on a normal diet. Conclusions: This experiment was very conclusive, mealworms prefer dark locations. Mealworms are not only able to eat various forms of plastic, as previous research has shown, they can consume potentially toxic plastic additives in … They found that microorganisms in the worms' guts biodegrade the plastic in the process -- a surprising and hopeful finding. Not only are they able to consume various forms of plastic, as previous Stanford research has shown, they can eat polystyrene containing a common toxic chemical additive and still be safely used as protein-rich feedstock for other animals, according to a new Stanford A new Stanford study shows mealworms can eat polystyrene containing a common toxic chemical additive and still be safely used as protein-rich feedstock for other animals. Not only are they able to consume various forms of plastic, as previous Stanford research has shown, they can eat polystyrene containing a common toxic chemical additive and still be safely used as protein-rich feedstock for other animals, according to a new Stanford study published in Environmental Science & … Now Anja Brandon, a student at Stanford University, and her research supervisor, Craig Criddle, have found that bacteria in the guts of mealworms can break down polymers much more quickly.Other researchers had already found that mealworms can digest a particular plastic called polystyrene. However, concern remained about whether it was safe to use the plastic-eating mealworms as feed for other animals given the possibility that harmful chemicals in plastic …
Others had their plastic meals supplemented with wheat bran. And the plastic-eating worms didn’t appear to be less healthy than worms eating a more natural diet. ScienceDaily. While hopeful for mealworm-derived solutions to the world's plastic waste crisis, they caution that lasting answers will only come in the form of biodegradable plastic replacement materials and reduced reliance on single-use products. Best of all were the worms that were given bran with their plastic.
Ms Brandon and Dr Criddle wondered whether polystyrene was uniquely palatable, or whether the bacteria in the worms’ guts might be able to eat other sorts of plastic, too. "Mealworms safely consume toxic additive-containing plastic." After 16 days, about half of the carbon from the polystyrene came out of the mealworms as waste. Hypothesis: We hypothesize that the mealworms will attack each other in the absence of food. If the worms found it nutritious as well, that would suggest their tastes might be usefully wide-ranging.More than 90% of the worms survived the 32-day experiment. The worms can then be used as a safe, protein-rich feed supplement.Tiny mealworms may hold part of the solution to our giant plastics problem. (Wheat bran had been found to increase the rate at which mealworms could digest polystyrene). To check, they turned to polyethylene, which is both more common than polystyrene and very different in chemical terms. It serves as a proof of concept for deriving value from plastic waste. According to the Stanford study, a single meal worm can eat 46.36 mg of polystyrene waste a year. That was significantly more than the worms eating polystyrene, who managed just 0.57 grams of the stuff. (Wheat bran had been found to increase the rate at which mealworms could digest polystyrene). Tiny mealworms may hold part of the solution to our giant plastics problem. With it, they excreted the HBCD – about 90 percent within 24 hours of consumption and essentially all of it after 48 hours. The additive is one of many used to improve plastics' manufacturing properties or decrease flammability.
Materials: - One plastic cup - Mealworms Procedure: Place all of your mealworms in a plastic cup with no food resource. Have any problems using the site? Tiny mealworms may hold part of the solution to our giant plastics problem. The process is fairly slow. "It reminds us that we need to think about what we're adding to our plastics and how we deal with it. (2019, December 19). Get weekly and/or daily updates delivered to your inbox.
"This work provides an answer to many people who asked us whether it is safe to feed animals with mealworms that ate Styrofoam," said Wei-Min Wu, a senior research engineer in Stanford's Department of Civil and Environmental Engineering who has led or co-authored most of the Stanford studies of plastic-eating mealworms.Brandon, Wu and their colleagues looked at Styrofoam or polystyrene, a common plastic typically used for packaging and insulation, that is costly to recycle because of its low density and bulkiness.
This means the mealworms are uncontaminated even if they substituted on styrofoam.
Most of the rest was converted to carbon dioxide. More importantly, the study might have revealed a new approach to waste management, including the potential for industries to explore the option of using mealworms to treat plastic wastes.
With it, they excreted the HBCD – about 90 percent within 24 hours of consumption and essentially all of it after 48 hours. "It's amazing that mealworms can eat a chemical additive without it building up in their body over time.
