Alright, gather ‘round folks! Today we’re diving into a topic that’s as sticky as a McDonald’s drive-thru floor in summer—a new bioplastic. Forget about that 3D-printed pizza you saw on Instagram; we’re talking about MECHS—Mechanical Engineered Living Materials. Sounds like a sci-fi movie, doesn’t it? “MECHS: The Bioplastic Awakens.”
So, what’s the scoop? We’ve got scientists at Northeastern University leading the charge against our plastic apocalypse. I mean, let’s be honest, if you’ve ever stepped into the ocean and come back with more plastic than you came with, you’ll appreciate this invention. Avinash Manjula-Basavanna and Neel S. Joshi saw the horror of synthetic plastic pollution—those pesky wrappers clinging to your leg while you try to enjoy a day at the beach. They decided enough was enough and created MECHS.
Now, technically, what is MECHS? It’s bioplastic that can compost, heal, and actually scales up—unlike that sad banana bread everyone made during the lockdown. MECHS can stretch like my waistband after the holidays and can even respond to stimuli like a well-trained dog, except it doesn’t require a treat or a scruff behind the ears. Check this out: if you toss it in water or compost, it says, "Thanks for the vacation!" and disappears faster than your motivation to hit the gym in January!
The two main reasons this bioplastic is making headlines are quite impressive. First off, it’s inspired by nature—meaning it can regenerate and adapt. Nature’s like that friend who’s a bit of a show-off but always has your back. And second, it actually biodegrades. Unlike those pesky plastic food containers that refuse to leave your fridge long after you’ve moved on to a new meal plan, MECHS can be flushed down the loo. Imagine that! “Hey, love, can you take out the trash?” “Nah, highly recommend just flushing it!”
Now, you might be thinking, "What about all the E. coli lurking about?" Not to worry! This engineered E. coli is more like “E. coli 2.0” for materials. It’s all about using bacteria for good; after all, that’s what it’s there for, right? It’s crafting a fibrous structure that can be used in everything from your new phone’s packaging to plant pots! Imagine a world where your iPhone comes in packaging that can actually make your plants thrive. “Thanks, Apple, I didn’t just buy a phone; I adopted a new plant!”
Of course, there are a few hiccups in scaling this miracle material. We need to make sure our engineered bacteria don’t turn rogue! We can’t have them plotting to take over Earth while trying to break down your leftover takeout container! Also, industries using traditional plastics might throw a tantrum—slightly more complex than getting a toddler to share their toys. We’ll need change, and it’s going to take some time, money, and lots of convincing, like trying to explain TikTok to your parents.
But fret not! The future of sustainable materials looks brighter than the glow of a half-burnt candle from your last romantic meal. As research advances, we could see more flexible, adaptable materials that’ll transform industries. The dream is to create biodegradable materials tailored for specific applications—and who wouldn’t want to contribute to saving the planet while still binge-watching their favorite Netflix series?
So, what’s the takeaway? Embracing nature-inspired innovations could just reshape our relationship with materials as we know it. We’re not just looking at a better bioplastic; we’re staring down the barrel of a sustainable future—one compostable toilet roll at a time! Who knew saving the planet could get this fun?
For more on this groundbreaking research, be sure to check out the full article published in Nature Communications. Because if we don’t laugh about our plastic crisis, we might just cry. And nobody wants to be that person holding a soggy plastic bottle in the ocean, right?
Birth of a new bioplastic
Manjula-Basavanna collaborated with Neel S. Joshi, a prominent associate professor of chemistry and chemical biology at Northeastern University, leading to the innovative creation of a groundbreaking bioplastic called MECHS.
MECHS stands for Mechanical Engineered Living Materials with Compostability, Healability, and Scalability.
Recently, the research team had their findings published in the distinguished journal Nature Communications, highlighting their pioneering work in engineered living materials—living cells designed to synthesize functional materials.
Wonders of bioplastic
MECHS stands out for two key reasons presented by Manjula-Basavanna and Joshi.
Firstly, it showcases nature-inspired solutions, possessing the remarkable capacity for self-regeneration and self-regulation while reacting intelligently to environmental stimuli such as light.
Unlike the deleterious plastics currently dominating the environment, MECHS biodegrades both in water and compost facilities, presenting a promising alternative.
“Right now we use a lot of conventional nonbiodegradable plastics for applications they don’t need to be used in at all,” Joshi emphasizes. “If we replace that with our plastic, you could just flush it down the toilet and it would biodegrade.”
Engineered living materials
Traditionally, engineered living materials have not been scalable for broad production; however, MECHS changes that dynamic.
This innovative bioplastic consists of engineered E. coli bacteria integrated into a fibrous matrix, forming a material reminiscent of paper or film.
The structural design imparts essential properties to MECHS, such as the ability to stretch akin to plastic wrap, while also allowing genetic modifications for varied stiffness. Notably, it possesses the ability to self-heal.
The icing on the cake? MECHS can dissolve completely in ample water or within a compost environment, breaking down far more rapidly than conventional biodegradable plastics. Furthermore, it can be produced en masse akin to paper.
Potential applications
Experts foresee MECHS effectively addressing the essential “primary packaging” sector, which encompasses everything from protective covers for electronics to detergent pods. Picture MECHS enveloping a potted plant, gradually decomposing and nourishing the plant with proteins!
Manjula-Basavanna underscores the significant potential of MECHS in the realm of plastic packaging, a segment that constitutes nearly one-third of the entire plastic market.
While conventional packaging lasts from several days to two years, the petrochemical plastics in use can linger in the environment for hundreds of years.
“For such a short lifespan of packaging, the petrochemical plastics that can take hundreds of years to biodegrade are unnecessary in many cases. A sustainable alternative like MECHS, with its biodegradability, flushability, and mechanical adaptability, could revolutionize the industry,” notes Manjula-Basavanna.
Challenges in adopting MECHS
While MECHS showcases a substantial breakthrough in tackling the plastic crisis, transitioning this innovation into mainstream adoption is fraught with hurdles. A crucial concern lies in ensuring the genomic stability of the engineered E. coli bacteria employed in MECHS.
The stability and safety of these bacteria must be assured across diverse environmental conditions to prevent unintended consequences. Additionally, industries that depend on traditional plastics face economic and logistical barriers when shifting towards MECHS.
Production facilities globally may necessitate adopting new techniques and infrastructure to support this novel material, potentially accruing considerable costs in the short run.
Public perception and regulatory challenges must also be addressed to build trust and secure the necessary approvals for wide-scale usage.
Future of sustainable materials
As research continues to evolve around MECHS, it heralds a new era for sustainable and versatile materials poised to reshape various industries.
With ongoing studies into living materials, intriguing opportunities arise, including the development of dynamic, adaptable materials for yet-to-be-conceived technologies.
Building upon their success with MECHS, Manjula-Basavanna and Joshi envision a broadened range of biodegradable materials customized for diverse applications—from environmental preservation to healthcare solutions.
Their work stresses the importance of interdisciplinary collaboration, merging biology, chemistry, and engineering to propel sustainable innovations.
Ultimately, MECHS exemplifies how harnessing nature-inspired ingenuity can yield breakthroughs with the potential to transform our interaction with materials and the environment we occupy.
The study is published in the journal Nature Communications.

How can educational initiatives encourage the adoption of MECHS among consumers and industries?
Awareness and acceptance will also require educational initiatives to inform consumers and industries about the benefits of MECHS over conventional plastics. It’s all about making sure people know that flushing a bioplastic is a valid and eco-friendly alternative to tossing it in the trash.
Furthermore, regulatory approval is essential for bioplastics like MECHS to make their way into the market, and navigating the compliance landscape can be complex. Stakeholders must collaborate with policymakers to establish guidelines for the safe use of engineered living materials.
while MECHS represents a remarkable step forward in the quest for sustainable alternatives to traditional plastics, its successful implementation will depend on overcoming these technical, economic, and societal challenges. Still, the potential impact on reducing plastic pollution and enhancing environmental sustainability is significant. The journey from laboratory innovation to everyday practicality might be long, but the vision for a cleaner planet powered by biodegradable solutions is certainly worth the effort.
