    Antibiotic resistance strains have been an issue of concern for many years.  Researchers at Rice University have come up with a new strategy to deal with them in wastewater treatment, they call it “wrap, trap, and zap.”

    Read the article below which was taken from Science Daily.

    Better wastewater treatment? It's a wrap

    A shield of graphene helps particles destroy antibiotic-resistant bacteria and free-floating antibiotic resistance genes in wastewater treatment plants.

    The labs of Rice environmental scientist Pedro Alvarez and Yalei Zhang, a professor of environmental engineering at Tongji University, Shanghai, introduced microspheres wrapped in graphene oxide in the Elsevier journal Water Research.

    Alvarez and his partners in the Rice-based Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment (NEWT) have worked toward quenching antibiotic-resistant "superbugs" since first finding them in wastewater treatment plants in 2013.

    "Superbugs are known to breed in wastewater treatment plants and release extracellular antibiotic resistance genes (ARGs) when they are killed as the effluent is disinfected," Alvarez said. "These ARGs are then discharged and may transform indigenous bacteria in the receiving environment, which become resistome reservoirs.

    "Our innovation would minimize the discharge of extracellular ARGs, and thus mitigate dissemination of antibiotic resistance from wastewater treatment plants," he said.

    The Rice lab showed its spheres -- cores of bismuth, oxygen and carbon wrapped with nitrogen-doped graphene oxide -- inactivated multidrug-resistant Escherichia coli bacteria and degraded plasmid-encoded antibiotic-resistant genes in secondary wastewater effluent.

    The graphene-wrapped spheres kill nasties in effluent by producing three times the amount of reactive oxygen species (ROS) as compared to the spheres alone.

    The spheres themselves are photocatalysts that produce ROS when exposed to light. Lab tests showed that wrapping the spheres minimized the ability of ROS scavengers to curtail their ability to disinfect the solution.

    The researchers said nitrogen-doping the shells increases their ability to capture bacteria, giving the catalytic spheres more time to kill them. The enhanced particles then immediately capture and degrade the resistant genes released by the dead bacteria before they contaminate the effluent.

    "Wrapping improved bacterial affinity for the microspheres through enhanced hydrophobic interaction between the bacterial surface and the shell," said co-lead author Pingfeng Yu, a postdoctoral research associate at Rice's Brown School of Engineering. "This mitigated ROS dilution and scavenging by background constituents and facilitated immediate capture and degradation of the released ARGs."

    Because the wrapped spheres are large enough to be filtered out of the disinfected effluent, they can be reused, Yu said. Tests showed the photocatalytic activity of the spheres was relatively stable, with no significant decrease in activity after 10 cycles. That was significantly better than the cycle lifetime of the same spheres minus the wrap.

    It’s 9:00 pm and I’m tidying up after my 8-year-old who is running through the house with the 11-year-old on her tail. They aren’t playing tag or hide and seek. They are saving moths from the evil clutches of our ravenous puppy. Like everyone in town, our house is overrun with moths – Miller Moths to be exact. The puppy loves to eat them, the kids don’t want innocent lives to be lost. It’s a continuous battle.

    Miller Moths are a normal part of life in Colorado in the summer. Their lives begin as eggs which hatch into cutworms on the plains. The cutworms feed voraciously on alfalfa, wheat, and other plants and continue growing all winter. Then in the spring, they pupate underground and after a few weeks, they emerge as moths and migrate west to feed on nectar in the Rockies. The migration generally begins in late May to early June and lasts for 4-5 weeks with the first 2-3 being the worst. The number of moths flying around town depends on many things; cutworm predation, moth predation, weather conditions, and availability of vegetation to eat.

    Experts say this is actually just an average year. The last four years have been below average, skewing memories to make this year appear particularly bad. It turns out 1991 was the “heaviest, most prolonged flight of Miller Moths across Eastern Colorado.” I remember spending hours setting up buckets and bowls of soapy water under lamps in attempts to capture the Miller Moths for removal. The moths were so bad that year they would pile up an inch deep in garage window frames.

    In addition to our short memories, why does this “average” year seem so bad? Drier spring conditions in Colorado combined with the late April frost wiped out some of the vegetation, leaving less food and condensing the Millers around Denver to feed on the nectar from the remaining flowers. Whatever the reason, these moths have brought a level of excitement to our house every night. And you may be wondering why they are called Miller moths? According to the interwebs, the scales on the wings that frequently flake off reminded people of the flour dust that millers were covered in after their shift at the mill.

    To learn more about Miller Moths, check out these great websites that I referenced to write this blog post: 1) www.denver.cbslocal.com. Think Those Miller Moths are Everywhere? You’ll Be Seeing More of Them. By Karen Morfitt. May 25, 2020. 2) www.animalsake.com Looking for Information About the Miller Moths? Read These Facts. Accessed June 26, 2020.

    Hi! We hope this finds you and yours safe and healthy during this time!

    In this era of COVID, most drinking water professionals, wastewater professionals, and those that work in labs and other professions that provide assistance to maintain critical infrastructure have been classified as “necessary”, and most are required to go in to work, even if it is on a modified schedule. This requirement exposes many to vectors that those that are working from home are not exposed to. Most are not ‘on the front lines’, but their services keep permit requirements intact, water quality high,   and reassure the public that a new public health crisis does not evolve from failing water treatment. Remember, through all of the craziness your contribution matters, and we appreciate all that you do!

    One positive thing about coronavirus; it does not ‘survive’ water treatment. There have been no cases of coronavirus in drinking water. Likewise, standard wastewater disinfection also renders coronavirus incapable of transmitting disease. Just imagine how much worse everything would be if this was not the case!

    However, coronavirus is known to be present in wastewater. This can cause extra concern for wastewater operators, lab analysts, and others exposed to raw wastewater. Whether or not the coronavirus in wastewater can cause disease is still an open question that needs more study. Some studies show that coronavirus can survive for several days in wastewater, while other testing has shown that coronavirus is inactivated by going through a human gut. In any case, the good news is that no known case of COVID 19 is known to have been transmitted via wastewater. The CDC calls wastewater ‘low risk’ for COVID 19. The CDC, OSHA, and WEF all agree that the normal engineered and administrative measures, PPE, and hygiene measures protect wastewater workers sufficiently from COVID 19. While the risk is low, wastewater workers must exercise extra diligence at work, even while already taking added measures like wearing masks and social distancing. Additionally, WRRFs are not assured of being able to get sufficient PPE because of the higher world demand.

    While we hope that wastewater does not have extra risks for workers, the coronavirus in wastewater has the possibility of becoming an important weapon in the fight against COVID 19. Because coronavirus is excreted in the feces and urine of affected persons, coronavirus in a sewer can be an early warning of COVID 19, and can be representative of the spread in the sewershed. It can also give important and timely information to public health decision-makers. This is known as Water Based Epidemiology (WBE), or Environmental Surveillance (ES). This is a developing field related to COVID 19 and has several hurdles before becoming relevant, but it is looking hopeful.

    Researchers in The Netherlands are credited for being first to test wastewater for coronavirus. They found coronavirus in wastewater even before the first reported COVID infection in the sewershed. Thus, they established that coronavirus in the wastewater can be an early warning of COVID 19 in the population.

    There are also currently several efforts to analyze levels of coronavirus in wastewater, and then to correlate those levels to an estimated number of affected people in the service area. Wastewater is a different and more complex matrix that those normally used in virology labs and is analytically challenging. Additionally there is an unknown distribution of the viral pieces between liquid and solid in the wastewater. Known levels of quantification are not yet known, but would have to be low enough to be able to compensate for the dilution of the virus in the wastewater in order to be useful. Already a researcher at Arizona State University (ASU) claims to be able to detect one affected individual in a population of 2 million. Others estimate 1-3 cases per 100,000 people. Additional problems on the analytical side are getting representative samples, developing rigorous QA/QC protocols, unknown matrix effects, and unknown fate and transport of coronavirus.

    Once detected in wastewater, there are additional formidable challenges of correlating the level of coronavirus in the wastewater to the level of COVID infection in the population. This requires knowledge of the population, flow, temperature, time in the sewer, industrial/residential discharge ratios, the fecal shedding rate per person, and many other factors. It will apparently also require knowledge of the average size of human poop. (No need to set up a study for this though. A professor at MIT has already determined this. It is 200 grams.)

    Despite the challenges, the promise of WBE/ES - that wastewater could give us both an early warning of, and an accurate measure of COVID in the population – is enticing. It could detect COVID 19 in a population before there have been any confirmed cases. It could indicate when a second or third wave is beginning. It would be faster than individual testing. It would include asymptomatic carriers and would be more representative of the spread of the disease than the current biased numbers that are low since they are hindered by testing availability. It would be specific to each sewershed, so response measures could better meet specific needs. It could be scalable; from the entire service area of a large WRRF down to a sewer from a single neighborhood, school, or assisted living facility. Testing would be cheap, the sample abundantly available.

    The study of analytes in wastewater as they relate to current issues in the service population is not new. Illicit drugs, malaria, salmonella, other viruses, etc. have all been looked at in wastewater. Each case provides its own challenges, but they all confirm the interesting hidden value of wastewater, and its important relationship to its service area. And in this current crisis, it is another reminder of the important work that everyone in the water field does!

I also used some information from the Closing Ceremony of the WRF Virtual International Water Research Summit on Environmental Surveillance of Indicators of COVID 19 in Sewersheds, April 30, 2020. Please let me know if you would like more information, or if you have an interesting addition!

    A few weeks ago, I was finalizing details for an upcoming trip to Paris and Bath, UK when I received an email from Natalie reminding me that I was due for a Blog post for the RMWQAA website.  It just so happened that I was simultaneously looking at a map of the small town of Saltford where the Airbnb I had booked for the trip was located. Less than a mile from the cottage was the Saltford Treatment Works.   “Brilliant idea!” I thought to myself.   I hoped I could pop over to the wastewater plant and see how the Brits are doing things.  I did some searching online, found Wessex Water on Facebook, and sent a message.  They were happy to arrange a tour of their facility for me.  Splendid!

    Wessex Water is a district that serves about 2.8 million people in the areas of Bristol, Bath, Somerset, Dorset and nearby areas.  These cities are all in southwest England, west of London, and bordering Wales.  Although Wessex runs like a district, it is owned by YTL Power International out of Malaysia.

    On the morning of my visit, I drove past the Avon River where Wessex Water discharges.  Due to a storm named Henry, the river had recently topped its banks and flooded the road so I felt lucky to have a clear day for the Assistant Treatment Manager Julian Collins to show me around.

    Originally built in 1914, the Saltford Treatment Works originally had four (4) basins made of brick. They are still in use today.   Across the pond, they report in Liters per Second, which meant I had to do some conversions to figure out the facility’s current capacity.   Side note:  When looking for conversion calculators, I discovered there are American gallons and English gallons.  Plant capacity is between 11 and 13 MGD depending on which factors you use.   

    Much of the treatment is the same as in Colorado.  The difference is they have combined sewer and storm systems.  Large dedicated basins catch the overflow and provide containment during rain events.  Their Environment Agency regulates the industry and has minimum and maximum “consents” comparable to permit limits of similar capacity facilities.  


    Their Guidance Document details permit regulations.

    In contrast to the older, smaller Saltford plant is the Wessex Water Operations Center in Bath also within the Wessex District.  The district runs all operations from their state-of-the-art green building, built using as much recycled material as possible.  The building is equipped with solar power heating, rainwater collection and use, and eco-friendly everything!  Security is top notch too. They even use fingerprint and retina scans. 

    Wessex Water’s sister company, Geneco, operates multiple liquid waste treatment facilities that handle a variety of industrial and domestic wasteloads including dairy, septic, industrial cleaning products, landfill leachate, and food waste.  All residents have a food waste bin that is put out for regular collection along with the recycle and rubbish bins each week.   Food waste goes to the main facility in Bristol for large scale composting.  Sludge from the Saltford Treatment Works is also processed in Bristol for later biosolids application and generation of power from biogas. 

    There’s much more to Wessex Water and all of their operations, but I will have to check out the rest on my next visit.  In the meantime, it’s great to have new colleagues and contacts across the pond.  Cheers!

    The prominent days that we think of for the month of February are typically Valentine’s day and President’s day celebrated on February 14th and 17th respectively. However, there is another important day that is celebrated worldwide on February 2nd: World Wetlands day.  World Wetlands day (WWD) raises global awareness about the value of wetlands and originated in 1971 when the Convention on Wetlands was formed in the Iranian city of Ramsar on the shores of the Caspian Sea.1 The Convention on Wetlands is an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.2 The first celebration of WWD was in 1997 and continues to be celebrated today by government and community groups by promoting conservation, restoration, and the proper use of wetlands.

    According to the EPA, Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season. 3 There are two general categories of wetlands, coastal or tidal and inland or non-tidal wetlands, which support various types of vegetation and both aquatic and terrestrial animal species largely determined by the hydrology of the habitat. The functionality of wetlands is also essential in an ecosystem by acting as a water filter, through the absorption of excess nutrients and other pollutants before they reach larger bodies of water, and providing flood and erosion control, by slowing and absorbing floodwaters during periods of excessive rain.4 Additionally, wetlands are economically important due to recreational popularity and the commercial fish and shellfish industry. However, these vital habitats are disappearing at an alarming rate.

    Wetlands only account for 6% of the Earth’s land surface and are disappearing three times faster than forests due to factors such as development and climate change.5  This impacts 40% of the world’s plant and animal species that live or breed in wetland areas and threatens to deplete the rich biodiversity that these habitats provide.6 Thankfully, governments and other organizations recognized the enormity of these impacts and have now increased efforts toward the conservation and restoration of wetlands. The general public is encouraged to get involved through volunteer monitoring programs, participating in restoration projects, providing support through donations, and to continue the education outreach of why wetlands are so essential to our environment.

    Habits can have an enormous impact in the workplace—and we’re not just talking about nail-biting, junk food and cigarettes. Habits affect all aspects of a person’s behavior and they can influence how that person responds to the rules and regulations of a company, how they interact with their fellow employees and ultimately determine their performance level on the job.

    For most people, their habits are so ingrained it’s like they’re operating on autopilot when the habit kicks in. This is true for both good and bad habits; good habits can make us more efficient, and bad ones can get in the way of reaching goals. 

    Overcoming bad habits can be challenging, but being consciously aware of the change that needs to happen is the first step to establishing more effective habits.

    When creating new habits there are a few do’s and don’ts you should follow to make those habits stick. These same rules apply to replace a bad habit with a good one.

    First, you need to understand how habits work. Charles Duhigg, the author of The Power of Habit, presented a simple neurological loop at the core of every habit consisting of three components: cue, routine and reward. In order to more fully understand your habits, you need to break down your own habit loop. 

    Start by asking yourself two questions: When does your bad habit happen? What is the cue (trigger) that sets it in motion? 

    It’s important to identify the cue as the beginning of the routine. The reward that comes at the end is what prompts the routine to continue. Here are a few tips when trying to override a bad habit.

    1. Change your cue. Without first identifying the trigger, it’s hard to make an adjustment when trying to change your habits. If you can control the cue it’s easier to maintain your commitment to change the habit. But you need to be aware of what triggers your habit. Once you’re able to consciously attribute the cue to the routine, you need to adjust that pattern to achieve a change in behavior. For example, if going to the cafeteria on break ultimately leads to you buying junk food, then you need to find a new location to have your break. The cafeteria is the cue that leads to the routine of buying the sweet reward of junk food. Because you want to change that pattern, a good start is to change the cue. 

    2. Make a substitution. Cutting out the cues isn’t always going to be an option when it comes to an emotional trigger like stress. If you try eliminating a bad habit based on willpower alone or by quitting cold turkey, you could be setting yourself up for failure. Once the cue is identified, substitute a good habit for your bad habit so that the trigger will inspire a new routine of actions with a similar reward.  For example, often people go for smoke breaks at work to handle stress. Cue: Stress. Routine: Go outside for a smoke. Reward: Relief from stress. In order to change the bad habit to a good habit, when the stress trigger sets in, keep the habit of going outside the same but don’t go where the smokers are. Instead, take a walk. You’re still getting the break and taking time to calm down from the stress but you’re getting exercise instead of smoking. Often in this situation, the smoker finds it wasn’t really the cigarette that brought them relief after all but the break of being outside. 

    3. Be realistic. When making habits, one rule of advice is that you have to be prepared to fail. This is not to say that you should give up before you start, rather it indicates that it’s going to be hard so you should anticipate setbacks and not allow them to derail you completely. There are a lot of things that people tell themselves when it comes to habits. These excuses include thinking you need to start all over when you’ve had a slip up. Rather than give up when you slip up, just be sure to get back on track and move forward in a positive and healthy way. Another thing to keep in mind is that you should start small. Rome wasn’t built in a day and your habits aren’t going to become automatic immediately either.

    Don’t forget, you don’t have to do it alone. Letting people know about your intentions of changing your bad habits will also invite those people to keep you accountable. And who knows, you may inspire them to make a positive change themselves.

    Wastewater is a valuable resource that can be reclaimed into many beneficial products. The mix of biological, chemical, and physical techniques used in this form of reclamation is forced to become more creative as discharge requirements become stricter. Nutrient requirements are a good example. As phosphorus and nitrogen limits drop for many wastewater treatment plants, we have to get creative to find new and cost effective ways to remove these analytes from our treated waters.

    Algae is one solution to our nutrient woes that is getting attention from different utilities and research groups. Algal treatment can be applied to treat for ammonia, nitrogen, phosphorus, and carbonaceous biochemical oxygen demand (cBOD). Low operational costs paired with the added sales of harvested fertilizer makes this technology realistic for many utilities.

    Gross-Wen technologies (GWT) has developed a revolving algal biofilm (RAB) system where algae grows on a treadmill-like belt that is suspended vertically above the wastewater. The belt rotates in and out of the wastewater allowing the algae to consume CO2, nitrogen, and phosphorus until it is harvested and used to make bioplastics and/or fertilizer.

    Fig. 1. Gross-Wen Algae Treatment Technology.

    Unlike most off the shelf organic brands of fertilizer, this algae fertilizer has slow-release properties that prevents nutrient leaching and polluting of our waterways.

    GWT installed a commercial pilot program at Metropolitan Wastewater Reclamation District in Chicago, Illinois. During the three-year study, 64 tons of algae was produced per day and $30 million a year was made from selling the pelletized algae. Researchers at GWT project that a commercial-scale facility could process between 200,000 and 1 million gallons of wastewater per day.

    CLEARAS is another research company using algae to clean wastewater and harvest recycled algal biomass. Their technique is different than GWT in that it directly mixes the algae into the nutrient-rich wastewater. After the recovery of nutrients and CO2, the mixture is filtered apart, leaving a clean water stream and a return activated algal stream. Results of their nutrient reductions are shown in Figures 2 and 3.

    Fig. 2. Total phosphorus results comparing influent and effluent. Data set includes 234 separate trials. Average incoming phosphorus = 1.91 mg/L. Average treated phosphorus = 0.02 mg/L.

    Fig. 3. Ammonia results comparing influent and effluent. Data set includes 234 separate trials. Average incoming ammonia = 14.09 mg/L. Average treated ammonia = 0.49 mg/L.

    CLEARAS claims that their system is zero-waste, incurs lower operation and maintenance costs due to the lack of chemicals used and disposed, produces ultra low-levels of phosphorus, nitrogen, biochemical oxygen demand, and total solids, and the ability to easily scale to your facility.

    Regulatory changes and needs of our communities create the opportunity for utilities to innovate systems to become more sustainable, clean energy based, and cost effective. When making choices in the future regarding nutrient removal, algal treatment systems may be a good fit for your utility.

    The holidays are approaching fast, and with everything that needs to be done, this usually involves a higher level of water usage. Think: cooking a big meal, thawing out your turkey, and more bathroom breaks during the big Thanksgiving game. To help you cut down on your water usage, I’ve compiled some helpful tips to get you through the holidays:

    • Rather than thawing frozen food under running water, consider letting it thaw in the refrigerator or use the defrost setting on the microwave. According to FoodSafety, the recommended time for thawing a turkey in the fridge is approximately 24 hours for every 4-5 pounds.
    • Consider washing all your produce in a bowl of cold water instead of rinsing it under running tap water. This change can help to reduce the amount of water lost down the drain. Plus, the water leftover in the bowl can be reused for other purposes, such as watering plants around the house.
    • Rethink rinsing the dishes with running tap water and instead, let your dishes soak in a sink filled with soapy water. This simple shift uses significantly less water and has the added benefit of making clean-up a bit easier.
    • Food waste often leads to unnecessary water waste via the garbage disposal. To cut down on water usage, try to cook only what you need and cut down on the garbage disposal usage. Compost food scraps whenever possible, and when they are not compostable, tossing scraps in the trash is a better option than down the sink. Be sure also to avoid pouring any oils or grease down the drain as this can lead to clogged pipes -- and yes, resulting in more water usage.
    • When cooking vegetables, consider steaming as opposed to boiling. Steaming is a great way to conserve your water usage and has the added benefit of maintaining the nutritional value of the vegetables.  
    • Make the conscious decision only to run your dishwasher with full loads. Especially if you're hosting guests for a big meal, this shouldn't be too big of a problem with the high amount of dishes that you will be using. Cutting down on the number of times you run the dishwasher is a great way to reduce your household's water consumption.

    The holidays are a great time to spend time with the ones we love and to be thankful for all the wonderful things that our life provides. So, let us enjoy the holiday season, while also helping with water conservation in the process.

    In response to Richard’s Local Water News blog from earlier this year, this blog has been written to highlight some worldwide water news. As the new water year begins and the end of the calendar year approaches, here are five uplifting water stories that could help improve our quality of life down the road!

    • 1)     Agreements signed for the Reintroduction of Salmon to the Upper Columbia River:

    From Victoria News in Canada, three leaders of Indigenous groups and two governmental groups have agreed to begin the process of ensuring salmon can reach their once thriving numbers in the Upper Coloumbia River. For the last 80 years dams have prevented the salmon from traveling along their traditional migratory routes, many of these through the state of Washington. The lack of salmon making their traditional runs effects the entire ecosystem, so the First Nations and several governmental agencies made sure an agreement was signed to explore the best ways to reintroduce salmon. In turn, a way of life for the Syilx Okanagan, Ktunaxa, and Secwepemc peoples and their communities could be restored as they will have access to these fish once again. There are, however, plenty of things to consider, such as the best way to manage dams to allow the fish through, climate change, and how the reintroduced salmon will interact with some endangered species now in the basin. This is progress though, and in a world where so many of our ecosystems are consistently fragmented, progress towards reconnecting them is what we need. Read the full story at Vicnews

    • 2)     Global Science Award Given to Teen for Microplastic Removal:

    From The Journal in Ireland, an 18 year old from Ballydehob was given the top award in the 2019 Google Science Fair. His project focused on the removal of microplastics from water using ferrofluids and magnets. The teen did point out that while not as effective on polypropylene plastics, it did show effectiveness with fibers found in washing machines. The experiment showed removal of 87% of microplastics in water samples, with a sample size of 1,000 tests. Could ferrofluids be our answer to the rising microplastic issues? Meet the 18 year old who believes so and watch his presentation video at TheJournal

    • 3)     Microfragmenting of Coral to Help Grow Back Coral Reefs:

    This story is from late 2018 and comes from Tech Maven. Coral reefs can take up to 75 years to reach sexual maturity in nature, however after a coral broke into pieces in the lab a new study was born! Researchers at the International Centre for Coral Reef Research and Restoration found that the corals grew back to their initial sizes in a few weeks rather than the three years it took to grow the original coral piece. What scientists found even more amazing was that once these fragments grew and they touched each other, they recognized themselves and fused together forming one large coral. This process speeds up coral growth by nearly 40 times! The restoration process is in full swing along the Florida Keys. Read more about the crew and check out their BBC Earth Video online at Sci-Techmaven

    • 4)     Creating Drinking Water from Air:

    A story from March this year in the Jerusalem Post provides insight on the Isreali company Watergen, a group determined to bring clean water to just about anywhere in the world just by pulling it out of the atmosphere. Their devices have been improved yearly since they were established in 2009, and have already provided aid in disaster locations across the world, included the United States! Essentially, the device pulls in air, filters the air, then through their heat exchange and cooling process condenses into water. Once filtered and hardened the water can be used as fresh drinking water. With just an electricity supply, the largest generator can create 5000 gallons of drinking water in a day.

    • 5)     The Ocean Cleanup is Successfully Gathering Trash in the Pacific Ocean:

    This story comes out of the Netherlands and is the most recently updated story on this list. If you haven’t heard of The Ocean Cleanup it is worth following. The group was founded in 2013 with a goal of cleaning up the Great Pacific Garbage Patch using drifting systems and the ocean currents. The devices drift along the currents and collect plastic, and would just need to be “harvested” for their contents every few months by a small fleet of ships. In early October of this year they announced that the most recent prototype launched in June was successful in collecting and retaining both visible plastics and microplastics as small as 1mm. They still have much work to do in improving their design and growing their fleet, but once fully functional they hope to reduce the size of the garbage patch by half within the first 5 years! Obviously there is much to be done when it comes to cleaning up our oceans, but with companies like The Ocean Cleanup we are moving in the right direction. To learn more about the group, their design, and its sustainability check out their website at TheOceanCleanup.
