Natrx Shell Bag Innovation Being Put To The Test

Natrx is teaming up with the Chesapeake Bay Foundation (CBF) to introduce an innovative technology that aims to replace the commonly used, yet less desirable and less effective, plastic shell bags.

Traditionally, plastic shell bags have been utilized to bolster coastal resilience in low wave energy situations. These bags are typically filled with recycled oyster shells. However, the use of plastic in this method poses several challenges, as it tends to release harmful chemicals and disintegrates into harmful microplastics over time. Although more eco-friendly options like jute, coconut, or biodegradable plastics have been attempted, they haven't proven to be a sustainable long-term solution.

Enter Natrx - in collaboration with the CBF and various commercial partners - on a mission to develop a practical and high-performance alternative to plastic shell bags. Extensive research into natural fibers, coatings, and plastic alternatives revealed that fibers spun from basalt rock, a naturally occurring lava rock, hold immense promise. Basalt fibers have already demonstrated their efficacy across various applications since the late 1990s, and now, Natrx is working to adapt this material to create environmentally friendly shell bags.

Currently, this project with the CBF along the Elizabeth River is in its pilot phase, designed to put the material to the test in practical use. The basalt-based shell bags being utilized here are the first prototypes, and the primary objective is to assess their viability. Subsequent prototypes will follow, exploring a wider range of applications and possibilities.

Natrx Technology At the Center of CCA REEF Louisiana Program

"This technology could open the door for a new wave of CCA reef projects as we experiment with different module sizes and designs. In the future, we could conceivably create reef materials specifically designed to optimize each reef location."

-- John Walther, CCA Louisiana Vice President of Habitat 

A Natrx project and partnership with CCA, The Louisiana Department of Wildlife and Fisheries, Danos, and White Water Contractors in south Louisiana was featured on KATC 3 News.

This artificial reef project uses 128 Natrx ExoForms or "Cajun Coral" which were designed and manufactured specifically for the site.

"Located in about 20 feet of water, the new reef replaces that lost habitat, providing habitat for trout, redfish, and a diverse range of marine species, according to a spokesperson for CCA."

$9M grant aims to restore Waikīkī reefs with coral nurseries

A coral reef restoration project off iconic Waikīkī Beach has been recommended for a $9 million grant by the National Oceanic and Atmospheric Administration’s (NOAAOffice of Habitat Conservation.

The REEFrame project is a partnership by the University of Hawaiʻi at Mānoa, Conservation International, the Hawaiʻi Division of Aquatic Resources, the ocean technology firm Natrx, the ocean engineering firm Oceanit, and workforce development nonprofit ClimbHI. The project will run from summer 2023 to mid-2026.

“Many reefs in the region are now so degraded that there is little living coral, collapsing to the point where they no longer provide shelter for fish,” said the REEFrame science lead Mark Hixon from UH Mānoa’s School of Life Sciences. “Unfortunately, many reefs around Oʻahu and other highly populated Hawaiian Islands now have few parrotfish and other seaweed eaters. Our reefs are in danger of being lost to ocean warming unless we help them recover with these interventions.”

“We are honored to work with the people of Hawaiʻi on this innovative and inclusive approach to restoring our precious coral reefs,” said Matt Ramsey, senior director of Conservation International Hawaiʻi. “We need to do everything we can to ensure that our present and future generations will have the opportunity to enjoy the many benefits of healthy and thriving coral reefs.”

This initiative is one of nearly 150 projects across 30 coastal and Great Lakes states and territories that were recommended to receive a total of $562 million. Vice President Kamala Harris made the announcement on April 21. These investments are an effort to make communities and the economy more resilient to climate change, as part of the Biden-Harris Administration’s Investing in America agenda. The awards are made under NOAA’s Climate-Ready Coasts Initiative and are funded by the Biden-Harris Administration’s historic Bipartisan Infrastructure Law and bolstered by the Inflation Reduction Act.

Project details

Planning and working with local stakeholders and pending numerous permits, the team is proposing to build two permanent coral nurseries—each about 100 feet by 100 feet and about 6 feet tall—on a bare rock seafloor in about 55 feet of water about ¾ mile off Waikīkī Beach. Construction could begin by 2025 after specific plans, environmental studies and permits are finalized. Made of stacked 3D-printed concrete modules in organic shapes with many holes and overhangs for fishes and other sea life, the nurseries are intended to serve two purposes:

  • “Corals of opportunity,” which are living coral colonies dislodged by storms, ship groundings, anchor drags or other disturbances, will be attached to the structures for temporary keeping until they are later transplanted to areas lacking coral. The process is similar to transplanting nursery trees after a forest fire, helping to restore the forest.
  • By attracting fish, especially parrotfish (uhu) and other seaweed eaters that keep reef surfaces clean so corals can flourish, the complex structure of the nurseries will gradually be colonized by naturally settling coral larvae, eventually becoming coral reefs in their own right. A preliminary experimental study off Waikīkī by Hixon and his lab demonstrated the feasibility of this approach.

“Essentially, the project will assist the natural process of coral regrowth by providing the structural framework that is needed for a healthy reef ecosystem. This is why we call the project REEFrame,” said coastal engineer Mike Foley of Oceanit.

“The three-dimensional framework of the nurseries will attract fish and corals, eventually becoming productive fishing reefs in their own right,” added Matt Campbell of Natrx.

Project outreach

The team will consult with local and cultural organizations during the design phase of the project, learning from ocean users, incorporating historical Indigenous practices where appropriate, and educating the public about the goals of and science and engineering behind the project. The team recognizes the cultural, economic and biological value of the Waikīkī region, and aims to minimize any impacts in helping to restore this valuable resource.

ClimbHI will help connect project organizers with schools statewide to provide opportunities for student and educator involvement, as well as partnerships with various industries.

“REEFrame offers a way for our keiki to gain valuable hands-on experience with leading environmental organizations and businesses,” said Julie Morikawa, president of ClimbHI. “We look forward to building widespread participation with this project from our local communities.”

The Hawaiʻi Division of Aquatic Resources (DAR) will facilitate the permitting process for the project.

“This project is a positive step towards habitat restoration for the fisheries of our islands,” said Brian Neilson, DAR Administrator.

As climate change continues to warm the oceans, coral bleaching—where heat waves cause corals to turn white and often die—is becoming more common in Hawaiʻi and elsewhere. When corals die, they are soon covered by seaweeds unless abundant uhu and other fish eat them, freeing space for new corals to grow. Corals are like the trees of a forest, providing habitat for many species. No coral means no reef, no fisheries, no natural breakwaters, and no sustainable sources of new beach sand that reduces coastal erosion as sea levels continue to rise.

NOAA is excited to be supporting our partners’ innovative efforts to restore coral reefs off the coast of Waikīkī Beach,” said Carrie Selberg Robinson, director of NOAA‘s Office of Habitat Conservation. “Coral reefs provide countless benefits for fisheries and coastal communities, and reef restoration projects are crucial for preserving the future of these important habitats.”

Natrx Living Shoreline Project Featured in Virginia

A recent living shorelines project we were involved in was just written up in the Gloucester-Mathews Gazette-Journal. This National Fish and Wildlife Foundation grant-funded shoreline project made use of our Natrx ExoForms to combat erosion and provide ongoing coastal resilience. Check it out below:

mathews case shoreline natrx 1
SHERRY HAMILTON / GAZETTE-JOURNAL Betty Case, left, of Atlanta and Port Haywood received grant funding to help pay for a project to create a living shoreline along her property on the East River. The project uses new technology developed by Matt Campbell, right, president of Natrx Adaptive Infrastructure in Raleigh, North Carolina.

A grant-funded shoreline restoration project in Mathews is using a new technology developed by Natrx Adaptive Infrastructure to help create efficient, effective—and cost-effective—living shorelines.

Betty Case of Atlanta and Port Haywood has a long shoreline at her East River property, and she’s concerned about erosion that’s occurring due to wave action driven by winds coming up from Mobjack Bay.

A shoreline study conducted a number of years ago by Donna Milligan and Scott Hardaway of the Virginia Institute of Marine Science identified Case’s property as one of several sites in Mathews that needed shore protection, so when the Middle Peninsula Planning District Commission secured a National Fish and Wildlife Foundation grant to create a reach-based, resilient shoreline protection project, Case was contacted to see if she wanted to participate. Her answer was an enthusiastic yes.

Natrx is a Raleigh, North Carolina-based company that uses patented computer-based manufacturing to create custom concrete modules expressly designed for the needs of a specific site. President and head of engineering Matthew Campbell said his company focuses on nature-based solutions for coastal restoration. He said he had been in the business of coastal restoration for 20 years, and that “creative desperation” had eventually led him to come up with a system that could “do things more efficiently and effectively.”

He invented a new process for forming concrete, Dry Forming, which is a type of 3D printing with concrete, to develop structures that were a better fit for certain sites than riprap, which requires building a structure with large stones that, pyramid-like, is wider at the bottom than the top.

The exoforms Campbell’s company creates with the technology weigh about 250 pounds each and have rounded edges with rough surfaces and crevices that oysters like, he said. They’re made tall enough to break the waves before they hit the shoreline, but low enough so that sediment can be transported over them during storms. Water is maintained at the same level as the river, providing marsh grasses with proper nourishment. The structures can even be designed to dip lower in some places for fish to cross over, and the openings in them allow water to flow through.

One of the best things about Natrx structures, said Campbell, is that they are more cost-effective than riprap, able to cover two to three times the linear footage than rock for the same price.

“We’re trying to bring new tools to restoration and make the whole industry more efficient,” he said.

Milligan, an associate research scientist in VIMS’s Physical Sciences Department, said the long shoreline at Case’s property has different habitat components that need to be handled differently. The project, which has been about two years in the making, will involve placing Natrx structures in front of areas with existing but eroding marsh grasses to mitigate erosion by breaking the waves before they hit the marshland. Riprap will be placed offshore along high-energy areas that have already eroded, with sand fill behind it for planting grasses. The structures will provide substrate for oysters to grow and “hopefully become a nice oyster reef.”

Campbell said there appears to be a lot of demand for shoreline projects in this area, so he’s considering establishing a manufacturing site here as the demand for his product grows. Lewie Lawrence, director of the Middle Peninsula Planning District, said that the Captain Sinclair Lewis property in Gloucester that’s being managed for the county by the Middle Peninsula Public Access Authority would be a good potential location for manufacturing the Natrx modules.

Case said she’s thrilled at the expertise that’s being brought to her shoreline project and happy to be “an example in this area of what can be done.”

Danos Completes Nature-Based Coastal Restoration Projects

In late 2021, Danos completed four coastal restoration projects in south Louisiana on behalf of Shell Pipeline Company. The work will provide shoreline protection through a combination of customized 3D printed modules, nicknamed “Cajun Coral,” and advanced satellite image monitoring with partner Natrx, Inc. The project designs and installation procedures were tailored to local site conditions in order to enhance biodiversity and shoreline stability.

We look forward to continuing our joint work to facilitate effective, nature-based solutions and to quantify the benefits such as biodiversity, vegetation health and natural carbon sequestration.

Leonard Nelson
Natrx CEO

“Louisiana’s coast is vital to our industry and our environment,” said Paul Danos, CEO of Danos. “Using technology to help restore the ecosystem, is one way Danos is living our purpose of solving big challenges for our customers and our communities.”

“Shell is committed to making a positive contribution to biodiversity in critical habitat areas where we operate, such as Louisiana’s coast, while delivering safe and reliable operations,” said Greg Mouras, general manager operations, Shell Pipeline Company. “We value Danos and Natrx’s support in bringing innovative, nature-based projects to life which serve both objectives, enabling important sustainability benefits, including wetland conservation and oyster creation, while protecting our pipeline infrastructure.”

In partnership with Natrx, Danos managed the project on behalf of Shell, including designing the technical drawings and installation plans. Danos’ construction team then completed the infrastructure fabrication and aided in installation on-site, in the marshes of Terrebonne Parish.

 

Faster and Safer Installs

The Danos and Natrx team developed the concept of “Cajun Coral,” a solution that combats erosion while providing ongoing resilience through the growth of oysters and marsh. The structures were optimized to allow a controlled flow of water to pass which, in turn, provides a healthy new habitat for oysters. As water flows through the barrier, oysters are nourished and sediments are deposited that encourage new marsh growth, support marine life and provide protection that grows stronger and more resilient over time.

"Cajun Coral" builds resilience and promotes healthy habitat growth.

In 2019, Shell GameChanger and The Idea Village teamed up for an accelerator program, ENERGYx in New Orleans, to support startups and innovators with the potential to impact the future of Louisiana and coastal areas around the world. Natrx was one of the companies selected for the program, which focused on emerging innovative technologies for coastal construction and water management that improves the capital efficiency of real projects on-the-ground.

“The partnership with Danos and Shell Pipeline Company has created new techniques for adaptive management of natural systems in south Louisiana,” said Natrx CEO Leonard Nelson. “We look forward to continuing our joint work to facilitate effective, nature-based solutions and to quantify the benefits such as biodiversity, vegetation health and natural carbon sequestration.”

A Closer Look at The Natrx OysterBreak System

Nature based solutions can allow you to deploy material that you don’t pay for that helps protect essential habitat.  The videos below take you through key elements of the Oysterbreak solution, and performance during the heavy 2020 hurricane season.

The Natrx Oysterbreak (US Patent# 9144228B1) is a modular breakwater designed to support coastal protection through a high-strength modular design and special material additives to support biological growth.  The system can be manufactured at large scale through local pre-cast manufacturers.  The Oysterbreak design can be modified to support other key species such as corals, vegetative species upon request.  Over 50,000 linear feet of storm-tested living shorelines have been deployed utilizing modular Oysterbreak technology.

As opposed to other traditional construction techniques such as rock revetments and seawalls, the Oysterbreak leaves ecological shoreline transitions intact, which supports fisheries and helps ensure stability for storm resilience.  Natural growth provides additional strength development over time as shown in the plot below from a scientific test of an early installation at an erosional site at Rockefeller Wildlife Refuge.

 

 


The studies key findings included, paraphrased from Risinger, 2012:

Increased Height: Oyster shell height measurements of 50 cm were recorded after six months growth, with oyster counts exceeding 500 per m^2 on the artificial concrete modular breakwater reefs.

Increased Strength: A significant increase in ASTM 78 standards for flexural strength over time from an initial 28-day curing load of 100 lbs to loads of 479 lbs in six months and 1,344 lbs in two years.

Sediment Accretion:  Pilot scale breakwater emplacements dominated by biological growth accumulated nearly 4 m3 of sediment over four years, representing over 300% of original mass deployed.

Infrastructure Success at Golden Meadow

A first of its kind, technology-driven, adaptive approach to shoreline and habitat protection is successfully validated in the aftermath of Hurricane Zeta.

In the latest efforts of a long successful partnership, ConocoPhillips and Ducks Unlimited have implemented an innovative, technology-led, and nature-based approach to bolstering shoreline resilience in the communities of southern Lafourche Parish. Over the past eight years, ConocoPhillips and Ducks Unlimited have restored or enhanced over 800 acres immediately outside of the Larose to Golden Meadow Hurricane Protection System. This work provides shoreline protection, marsh enhancement, and terracing that increase the resilience of the levee system and the communities within. The goal of this particular project was to stabilize 750 feet of a newly completed marsh creation project. This area is exposed to increasing storm surges and weather events such as the set of storms hitting the Louisiana coast this year as well as erosion from day-to-day tidal action.

The project site presented numerous challenges including shallow water access, weak foundation soils, and the necessity to operate safely around established energy infrastructure. Natrx utilized its intelligent, adaptive infrastructure platform to create and install a set of custom reef modules nicknamed “Cajun Coral” by Louisiana-based Danos LLC, a key contractor on the project. "Danos is proud to have partnered on this innovative project to prevent erosion and strengthen our local wetlands. 'Cajun Coral' was born out of our team's desire to develop a name for the reef modules that reflected our local, South Louisiana culture," said Eric Danos, owner of Danos. 

3D Printed “Cajun Coral” Modules

Natrx Oyster Stakes

These modules were specifically designed to provide habitat-positive protection for the exposed segment of the site. Less exposed reaches were stabilized with a system of ultralight, hand-deployed oyster stakes which will develop into a robust oyster reef over time. This innovative approach creates a cost efficient, weather resilient, and habitat-friendly oyster reef shoreline protection system.

In the end, 180 feet of the custom-designed “Cajun Coral” was installed along with 620 feet of ultralight oyster stakes.  Thanks to the partnership’s modular, intelligence-driven production, delivery, and installation approach the entire protection solution exceeded safety targets by deploying with zero safety incidents. Immediately after installation, the project’s innovative approach proved successful by performing perfectly during a direct hit by Hurricane Zeta. A post storm assessment revealed new oyster spat growing on both the Cajun Coral and the oyster stakes.

ConocoPhillips and Ducks Unlimited are proud of their partnership that demonstrates how the latest innovations can be harnessed to enhance efficiency, reduce cost, and improve performance through micro-tailored solutions. The continued success of this fruitful partnership is in large part due to the contributions of several like minded organizations including: Lafourche Parish, Natrx, ORA Estuaries, Louisiana’s Coastal Protection and Restoration Authority, Danos LLC, MREC Environmental, and the National Fish and Wildlife Foundation.
