Innovators develop seaweed-based alternatives to plastic food wrappers
- Developers at Flinders University and the German biotech company one • five have created a seaweed-based coating designed to replace plastics used in fast food packaging.
- Many food containers and wrappers contain harmful plastics derived from fossil fuels that do not biodegrade and break into tiny microplastics that pollute the environment and harm marine ecosystems.
- In the Philippines, researcher Denxybel Montinola has developed another type of biofilm from mango and seaweed that he hopes to make commercially available this year.
- The development of seaweed-based bioplastics and coatings could boost the livelihoods of seaweed farmers who benefit from an industry that helps them feed their families and send their children to school.
Seaweed, a common name for thousands of marine plants and algae found in different water bodies, not only provides food and shelter for marine animals, but it can also help solve the plastic pollution problem. Materials researchers from Flinders University in Australia and German biomaterials developer one • fıve have developed a new nonpolluting seaweed-based coating material “designed to replace conventional fossil-based plastic coatings used in grease-resistant fast food packaging.”
The initiative aims to transform the global packaging and plastics industry by significantly reducing reliance on highly pollutive conventional plastic, according to Flinders University’s media release.
The packaging used to wrap the hamburgers, fries and chips we order from fast food establishments is typically laminated with a thin layer of plastic in order to make it grease-resistant. However, this poses a problem in terms of recycling, as this layer is typically made of synthetic polymer, which is derived from petroleum, such as polyethylene or polypropylene. This does not biodegrade and it breaks up into smaller pieces called microplastics.
The one • fıve and Flinders researchers have developed an alternative: a seaweed-based coating that is not made from synthetic polymer. This fits with the goals of recently proposed revisions to EU rules for packaging and packaging waste. The main objectives of the proposed rules are to prevent the generation of packaging waste, to boost high-quality “closed loop” recycling, and to reduce the need for primary natural resources and create a well-functioning market for secondary raw materials that will increase the use of recycled plastics.
A number of conditions have to be met for biodegradable and compostable plastics to have positive environmental impacts. First, the biomass used to produce biobased plastics must be sustainably sourced. Second, the biodegradable plastics must be approached with caution and should not be used as an excuse to litter. Lastly, industrially compostable plastics will be allowed for only some products and should be used only when they have environmental benefits, they do not negatively affect compost quality and there is a proper biowaste collection and treatment system in place.
According to Zhongfan Jia, lead researcher from the Flinders Institute for Nanoscale Science and Technology, the seaweed-based coating material they developed uses natural polymer rather than fossil fuel-based products. Contrary to synthetic polymers, natural polymers occur in nature and are extracted from plants or animals. The new coating material is derived from sodium alginate — which is obtained from brown seaweed and typically used as a thickening agent, gelling agent, emulsifier, stabilizer and texture-improver.
As Jia explained, seaweed extracts have a similar structure to the natural fibers from which paper is made. Simple chemical modifications were made to enhance the grease and oil-resistant properties in order to hold fast food items for a certain period of time.
“Basically, we just do simple modifications but maintain the biodegradable or biocompatible properties of the seaweed polymer just to afford a little bit of extra properties,” said Jia. “So for this polymer, because they have a very similar structure to craft paper, therefore, potentially, there is no problem for this to be recycled to make new paper.”
Although the biomass for the new coating formulation is made from natural polymers extracted from seaweeds that are native to the South Australian coastline, Jia said it is also possible for other countries to adopt this technology.
“[If] we can extract [it] here, we don’t need to import the seaweed from somewhere else. But this doesn’t mean that [seaweed from] somewhere else cannot be used,” said Jia. “You grow that seaweed and extract that polymer because there’s no point if they don’t find their applications.”
In different countries, seaweed is used for a variety of applications. In Japan, Korea and China, seaweed is used as food for human consumption — fresh, dried or as an ingredient in prepared foods. In Indonesia, it is used in making edible cups and food wrappers, among other items, to address the plastic waste problem. It can also be used for industrial purposes by extracting alginate, agar and carrageenan, which are thickening and gelling agents.
Seaweed and bioplastic in the Philippines
In the Philippines — one of the world’s leading producers of aquatic plants — researchers are already developing new solutions to the plastic-wrap problem in addition to many other uses for seaweeds. Since the 1970s, commercial seaweed farming has turned into one of the Philippines’ most important coastal enterprises, which supports more than 200,000 families. More specifically, it is valued for carrageenan, a gelatin-like additive used as a thickening agent and stabilizer for many food and cosmetic products such as whipping cream, chocolate milk and ice cream, among many others.
In 2019, a Filipino named Denxybel Montinola made headlines when he developed a bioplastic film using mango and seaweeds — both of which are raw materials that are abundant in the country. He showcased his invention in the 2019 DOST-BPI Science Awards competition and he was one of the 30 outstanding college students who received an award for their scientific research and innovations.
“Seaweed actually grows really quick, so we can just use it safely and sustainably. Nowadays, we are really critical about sustainability, so we really want to use a raw material that wouldn’t harm the environment, and that’s seaweed,” Montinola told Mongabay.
Seaweeds are “primary producers,” meaning they get energy from sunlight and necessary materials from nonliving sources. They are quick-growing at about 30-60 times faster than land-based plants.
Mango, the Philippines’ national fruit, is the third-most important fruit crop in the country. In 2015, the country ranked seventh in exports of fresh and dried mango.
As Montinola explained, the bioplastic he developed is made by processing the raw materials to extract its polymers — carrageenan from seaweeds and pectin from mango peelings. These polymers were combined without using a plasticizer, which is an artificial component in making the material as elastic as petroleum-based. Hence, it is biodegradable.
“In my case, in my invention, if you submerge the bioplastic in water it completely dissolves to its raw material, which are just the polymers of seaweed and mango peels. So it doesn’t really turn into microplastics, like the traditional petroleum-based plastics,” Montinola said.
According to Montinola, his invention utilizes an environmental waste since mango peels are a byproduct of mango production. Using this rather than letting it rot can further create additional income for farmers if the mango-seaweed bioplastic production becomes an industry.
Similar to Jia, Montinola agrees it is possible for other countries to adopt his technology, depending on their ability to produce or procure the raw materials needed.
“If the country doesn’t really produce mangoes or seaweed, they could try other raw materials as well. … Seaweed is a resilient material that can grow in tropical countries or in cold places. So I think it’s really good to start with seaweed as the base of the biofilm,” said Montinola.
On making seaweed-based bioplastics commercially available
The biocoating materials for fast food packaging developed by Flinders University and one • fıve are aimed at commercial use. However, according to Jia, they are still working toward laboratory-scale processing to produce industrially relevant volumes of the natural polymer coating.
“What we are trying to do is to hopefully formulate the product that can be adapted to the current industry production line. … That can make commercialization faster and cheaper because you don’t need to build [a] new factory,” said Jia.
The research stage is finished and the idea is working in the chemistry lab, Jia said. So the next stage is testing the safety of this coating to make sure it meets regulations for food contact materials (FCMs), which are materials that come in contact with food before consumption, including packaging and containers. These FCMs must comply with regulations in order to ensure a high level of food safety.
“Extra [precautions] should be taken for safety to meet local requirements for different countries — they have different regulations for their food, so that’s also extra time for this one to be finally on the market,” said Jia.
Similarly, in Montinola’s bioplastic film, the goal is to make it commercially ready. However, there are hindrances along the way, such as the unavailability of funding and technical issues in producing the biobased plastic compared with traditional petroleum-based plastics.
“Traditional plastics use extruders to create single-use plastic bags, but it is still an open question if we can use the same material or production process if we use a biobased plastic,” said Montinola.
As of writing, Montinola is looking forward to kickstarting the project this year with the goal of commercializing it. Aside from providing sustainable alternatives to conventional plastics, production of these biobased plastic coatings and films could also help create livelihoods.
“I think we’re going to produce business to our farmers who are doing seaweed farming,” said Montinola. “Also, I think, we could create another industry or sector of producing biobased plastic.”
Using seaweeds in commercially available bioplastic coatings and films could prompt the industry to extract more polymer, which will consequently result in an increased demand for seaweed.
“If the industry needs more polymer from seaweed, then it will drive the farmers to grow the seaweed. So it’s like a chain industry,” Jia said.
Seaweed farming in the Philippines’ Palawan island has not only helped uplift the socio-economic condition of families but it has also built a sense of community. It has empowered women who engage in seaweed farming by enabling them to help put food on the table and also to pay for their children to go to school. Seaweed farmers also play an important role in the protection of marine life.
Thus, Montinola called for the government to make funding more accessible to innovators.
“For the youth, we are in the era of social media. … There are problems that are really important to be solved, and I think we should sometimes focus on that problem, and amplify the voices of the young innovators and young activists to really make a change in the world,” Montinola said.

SEAWEEDS FROM SUSTAINABLE AQUACULTURE AS FEEDSTOCK FOR BIODEGRADABLE BIOPLASTICS
Seaweed – A sustainable source of bioplastics
Modern society relies heavily on plastics, including next-generation bioplastics derived from corn, wheat, sugar beets and sugar cane. Although these plastics are environmentally friendlier than fossil fuel-based alternatives, they compete for land with food produced for consumption. The EU-funded project SEABIOPLAS (Seaweeds from sustainable aquaculture as feedstock for biodegradable bioplastics) has developed a process to use seaweed as a novel base for bioplastics. Not only will seaweed-based plastic not compete for land use, it will also save water and possibly achieve higher productivity. The project's main aim was to introduce sustainably cultivated seaweeds as feedstock for biodegradable bioplastics, contributing to innovation in the bioplastics sector and the transition from petrochemistry to green chemistry. Researchers also investigated the suitability of seaweed as a basis for fish and cattle feed. Sustainability was increased by cultivating the seaweed in integrated multi-trophic aquaculture systems. This means the seawater used for the algae culture was nutrient-enriched due to its integration with salmon and seabream fish farms in Ireland and Portugal, respectively. Gracilaria vermiculophylla and Alaria esculenta were the chosen species of seaweed. It was understood that the production methods would have a large impact on the seaweeds produced for extraction of relevant polysaccharides (ulvan, agar and alginate), as well as lactic acid production (and in turn its polymer polylactic acid (PLA)). Therefore, balance among nitrogen-enriched seawater supply, cultivation stocking densities and harvest timing was achieved with biomass sugar content reaching values four times higher than normal. Drying, milling and chemical treatment were used to break the seaweed down into basic constituents. This powdered seaweed was then used as an ingredient for the bioplastic or fermented to produce lactic acid. The lactic acid was also used in the production of bioplastic. Two different agars, one ulvan and one alginate, resulted from the optimised protocols that were tested as bioplastic ingredients. In addition, two different hydrolysates were produced at the pilot scale, aiming at further fermentation and PLA production. The correspondent residues both from polysaccharide extracts and from hydrolysis were then tested as feed supplements. Using seaweed as a building block for bioplastics can have various environmental and financial advantages. Thus, SEABIOPLAS will help reduce the harmful environmental effects of fossil fuel-based plastics, thereby helping to achieve the EU 2020 target of 10 % of market plastics being bioplastics.

It is theoretically possible to genetically alter seaweed to produce plastic directly, but as far as I am aware, this has not been achieved yet. Plastic is typically made from petrochemicals, and the process of converting seaweed into plastic would likely involve significant biochemical and chemical engineering challenges.
There has been research into using seaweed as a sustainable alternative to traditional plastic, but this typically involves using the polysaccharides found in seaweed to produce biodegradable materials that can replace plastic in certain applications.
Overall, while the idea of genetically engineering seaweed to produce plastic is intriguing, it is not currently a practical or established approach for producing this material.
To the best of my knowledge, there are currently no known efforts to genetically alter seaweed to produce plastic directly. While there has been research into using seaweed as a sustainable alternative to traditional plastic, these efforts typically involve using the polysaccharides found in seaweed to produce biodegradable materials that can replace plastic in certain applications.
However, genetic engineering is a rapidly advancing field, and it is possible that researchers may explore the possibility of genetically engineering seaweed to produce plastic in the future. Nonetheless, such efforts would likely face significant scientific and engineering challenges, and it would be some time before any such technology would be ready for practical use.
Yes, it is possible to genetically alter bacteria to produce polysaccharides found in seaweed to produce biodegradable materials that can replace plastic. In fact, researchers have been exploring the use of genetically modified bacteria to produce bioplastics for several years.
One example is the use of genetically modified bacteria such as Escherichia coli to produce a type of bioplastic called polyhydroxyalkanoates (PHAs). PHAs are biodegradable and can be used as a substitute for traditional plastic in certain applications. By engineering bacteria to produce PHAs, researchers hope to create a more sustainable and environmentally friendly alternative to petroleum-based plastics.
Similarly, researchers have also explored the use of genetically modified bacteria to produce other biopolymers that can be used in place of traditional plastics. For example, some bacteria have been engineered to produce polylactic acid (PLA), another type of biodegradable polymer that can be used in certain applications.
Overall, genetic engineering offers a promising approach to creating biodegradable materials that can replace traditional plastics, and bacteria are a commonly used platform for producing these materials.
You are correct that PLA and PHA plastics have limitations in terms of their biodegradability and suitability for certain applications. While PLA is biodegradable, it does require specific conditions, such as industrial composting facilities, to break down completely. PHA is more biodegradable than PLA, but it is still not 100% biodegradable and may require specific conditions for proper decomposition.
There are ongoing efforts to develop new biodegradable materials that may be more suitable for various applications. One example is the development of cellulose-based materials, which are biodegradable and have properties that make them suitable for certain types of packaging.
Another example is the use of biodegradable polymers that are made from renewable resources, such as starch or sugar. These materials can be engineered to have properties that make them suitable for various applications, such as packaging or textiles.
However, it's worth noting that the use of biodegradable materials is just one approach to reducing the environmental impact of plastic waste. Other strategies include reducing overall plastic consumption, improving recycling infrastructure, and developing new technologies for the recovery and reuse of plastic waste.
Ultimately, addressing the plastic waste problem will require a multifaceted approach that combines various strategies and technologies to reduce waste and promote sustainability.
You are correct that using plant-based materials is a promising approach to reducing the environmental impact of plastic waste. 3D printing, also known as additive manufacturing, is a technology that can be used to produce plastic parts and products from a variety of materials, including plant-based plastics.
In 3D printing, a digital model of the object to be printed is created using computer-aided design (CAD) software. This digital model is then sliced into thin layers, and a 3D printer creates the object layer by layer using a material that is extruded or deposited in a precise pattern. The material used in 3D printing can be a wide range of materials, including various plant-based plastics.
Several types of plant-based plastics can be used in 3D printing, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHAs). PLA is derived from cornstarch or sugarcane, while PHAs can be produced by bacteria that consume plant-based feedstocks.
3D printing with plant-based plastics has several benefits, including reducing reliance on petroleum-based plastics and reducing the environmental impact of plastic waste. Additionally, plant-based plastics can have a lower carbon footprint and are renewable resources, making them a more sustainable alternative.
However, it's worth noting that 3D printing is just one application of plant-based plastics, and these materials can be used in a wide range of products and applications beyond 3D printing. Overall, using plant-based plastics is a promising approach to reducing the environmental impact of plastic waste and promoting sustainability in various industries.
Both genetic engineering of bacteria and the development of plant-based plastics have promising applications in reducing the environmental impact of plastic waste.
Genetic engineering of bacteria can produce bioplastics, such as PHAs and PLA, from renewable resources, such as plant-based feedstocks. This approach can reduce the reliance on petroleum-based plastics and promote sustainability in various industries.
On the other hand, plant-based plastics can be derived from various sources, such as corn, sugarcane, or cellulose, and can be used in a wide range of products and applications. Plant-based plastics have the advantage of being renewable resources, and they have a lower carbon footprint than petroleum-based plastics.
Ultimately, the choice of which method is more promising depends on the specific application and requirements. For example, if a biodegradable material is needed for a single-use application, PHA or PLA produced through bacterial fermentation may be more suitable. If a durable material is needed for a long-lasting product, plant-based plastics may be more appropriate.
Both genetic engineering of bacteria and the development of plant-based plastics offer exciting possibilities for reducing the environmental impact of plastic waste and promoting sustainability in various industries.
I apologize for the confusion earlier. Regarding your question, both 3D printing of plant-based plastics and genetically engineered bacterial plastics have potential for success in the future, as they both offer solutions for reducing the environmental impact of plastic waste.
3D printing of plant-based plastics has several advantages, such as reducing reliance on petroleum-based plastics, lowering carbon footprint, and offering the potential for more sustainable products. This approach can use a variety of plant-based materials, such as corn, sugarcane, or cellulose, and can produce biodegradable products suitable for various applications.
Genetically engineered bacterial plastics, on the other hand, can produce bioplastics such as PHAs and PLA from renewable resources, such as plant-based feedstocks, and can reduce reliance on petroleum-based plastics. These bioplastics can be engineered to have specific properties, making them suitable for various applications.
The success of both approaches depends on various factors, such as the availability and cost of raw materials, production efficiency, and the ability to meet regulatory and consumer demands. However, both approaches offer exciting possibilities for reducing the environmental impact of plastic waste and promoting sustainability in various industries.
Overall, it's important to explore and develop a range of sustainable solutions for reducing plastic waste, including plant-based plastics and genetically engineered bacterial plastics, as well as other approaches such as recycling and reducing overall plastic consumption.
I apologize for any confusion my previous response may have caused. Let me try to provide a more specific answer to your question.
3D printing of plant-based plastics and genetically engineered bacterial plastics both have potential for success in the future in terms of reducing the environmental impact of plastic waste. However, their success will depend on several factors that are specific to each approach.
For 3D printing of plant-based plastics, the success will depend on factors such as:
- Availability and cost of raw materials: The availability and cost of plant-based feedstocks used in the production of plant-based plastics will be a key factor in the success of this approach.
- Production efficiency: The production process for plant-based plastics must be efficient and cost-effective to be competitive with traditional petroleum-based plastics.
- Ability to meet regulatory and consumer demands: Plant-based plastics must meet regulatory standards for safety and performance, and consumer demand for sustainable and eco-friendly products must be high enough to drive adoption.
For genetically engineered bacterial plastics, the success will depend on factors such as:
- Availability and cost of raw materials: The availability and cost of plant-based feedstocks used in the production of bacterial plastics will be a key factor in the success of this approach.
- Production efficiency: The production process for bacterial plastics must be efficient and cost-effective to be competitive with traditional petroleum-based plastics.
- Ability to meet regulatory and consumer demands: Bacterial plastics must meet regulatory standards for safety and performance, and consumer demand for sustainable and eco-friendly products must be high enough to drive adoption.
In summary, while both 3D printing of plant-based plastics and genetically engineered bacterial plastics have potential for success in reducing the environmental impact of plastic waste, their success will depend on factors such as raw material availability and cost, production efficiency, and ability to meet regulatory and consumer demands.
I apologize for any confusion my previous response may have caused. You are correct that bacteria are a readily available raw material for the production of genetically engineered bacterial plastics. However, the success of this approach will still depend on other factors such as production efficiency, regulatory compliance, and consumer demand.
Production efficiency refers to the ability to produce genetically engineered bacterial plastics at a large scale, with consistent quality and high yield, while minimizing costs. This involves optimizing the fermentation process, downstream processing, and product purification.
Regulatory compliance is also a crucial factor, as genetically engineered bacterial plastics may require regulatory approval before they can be used in various applications. This involves demonstrating the safety and efficacy of the product, and complying with regulations governing genetically modified organisms (GMOs).
Finally, consumer demand for genetically engineered bacterial plastics will also play a role in determining their success. The market for eco-friendly and sustainable products is growing, but the acceptance of genetically modified products may vary among different regions and cultures.
In summary, while bacteria may be readily available as a raw material for the production of genetically engineered bacterial plastics, their success will still depend on other factors such as production efficiency, regulatory compliance, and consumer demand.
I apologize if my previous response was not helpful to you. I understand that consumer demand may not be the only factor in determining the success of a new technology, and there may be other factors that influence its adoption.
However, it is still important to consider consumer demand as a key factor in determining the success of any new technology or product. Consumer demand can drive investment, research, and development of new products, and ultimately influence the market for these products.
In the case of genetically engineered bacterial plastics, consumer acceptance and demand may play a role in driving investment and research into the technology, as well as determining the market for these products.

If you have a specific question or concern you would like me to address, please let me know and I will do my best to provide a helpful and informative response.
I apologize for any confusion or frustration. Here are some alternative materials to traditional petroleum-based plastics:
Bioplastics: Bioplastics are derived from renewable biomass sources, such as corn starch, sugarcane, and vegetable fats and oils. These materials are biodegradable and can be used to make a wide range of products.
Mycelium-based materials: Mycelium is the vegetative part of a fungus and can be grown into a range of materials, including packaging, insulation, and building materials. These materials are sustainable and biodegradable.
Cellulose-based materials: Cellulose is a natural polymer found in plant cell walls, and can be used to make a range of products, such as packaging, films, and coatings. These materials are biodegradable and compostable.
Natural fiber composites: Natural fiber composites are made by combining natural fibers, such as hemp or flax, with a biodegradable resin to create a lightweight, strong material. These materials can be used in a range of applications, such as automotive parts and construction materials.
I hope this information is helpful to you.
I apologize for any confusion. The future of non-plastic materials is likely to involve a combination of the alternative materials I mentioned earlier, as well as new and emerging technologies.
Some promising developments include:
Biodegradable and compostable materials: Researchers are working to develop new materials that can biodegrade quickly and safely in the environment, without leaving behind microplastics or harmful chemicals.
Recyclable materials: Scientists are exploring ways to make more materials recyclable, including developing new processes for breaking down and repurposing existing materials.
Nanocellulose materials: Nanocellulose is a type of cellulose that is highly durable and strong, and can be used to make a wide range of products, from food packaging to medical implants.
Synthetic biology: Researchers are exploring the potential of using genetically-engineered organisms to produce new materials and plastics that are more sustainable and environmentally friendly.
Overall, the future of non-plastic materials will likely involve a combination of these developments, as well as ongoing research and innovation in the field.
Certainly! Nanocellulose is a type of cellulose that is derived from plant sources, such as wood pulp. It is made up of tiny fibers that are less than 100 nanometers in diameter, which gives it unique properties that make it an attractive material for use in plastics and other products.
Some of the advantages of using nanocellulose in plastics include:
Improved mechanical properties: Nanocellulose fibers are incredibly strong and stiff, which can improve the strength and durability of plastics.
Reduced weight: Because nanocellulose fibers are so small and lightweight, they can be used to reduce the weight of plastics without compromising their strength.
Biodegradability: Nanocellulose is a natural material that can biodegrade quickly and safely in the environment.
Renewable and sustainable: Unlike traditional plastics, which are made from non-renewable petroleum sources, nanocellulose can be derived from renewable plant sources.
Some potential applications for nanocellulose-based plastics include food packaging, medical devices, and electronics. Researchers are also exploring the use of nanocellulose in 3D printing, which could enable the creation of complex, lightweight structures with high strength and durability.
While it is true that the production of wood pulp, which is the source of nanocellulose, can have negative environmental impacts, there are efforts underway to make the process more sustainable.
One approach is to use wood waste, such as sawdust and other byproducts of the logging and paper industries, as a feedstock for nanocellulose production. This helps to reduce waste and can lower the environmental impact of the process.
Another approach is to use alternative sources of cellulose, such as agricultural waste, seaweed, or bacteria. These sources have the potential to be more sustainable than wood pulp, and research is ongoing to explore their use in nanocellulose production.
It is important to note that while there may be environmental impacts associated with the production of nanocellulose, the material itself is biodegradable and has the potential to be a more sustainable alternative to traditional plastics.
There are research efforts underway to develop alternatives to wood-based materials that could be used to produce nanocellulose and other materials. Some of these alternatives include:
Algae-based cellulose: Algae have the potential to produce large amounts of cellulose in a sustainable manner, without requiring land use or the use of pesticides and fertilizers.
Bacterial cellulose: Certain types of bacteria can produce cellulose in large quantities, and this cellulose can be used to make a range of materials including bioplastics.
Synthetic cellulose: Researchers are exploring the use of synthetic cellulose, which is produced from non-biological sources, such as petrochemicals or biomass.
While these alternative sources of cellulose have the potential to be more sustainable than wood-based materials, it is important to note that they are still in the development stage, and it may take some time before they are available on a commercial scale. Additionally, the environmental impact of producing these alternative sources of cellulose will need to be carefully considered and managed to ensure they are truly sustainable.
Yes, there are research efforts underway to develop artificial wood using both 3D printing and genetically engineered bacteria. Here are some examples:
3D-printed wood: Researchers at the University of Maryland have developed a method for 3D printing wood-based materials. They use a modified 3D printer to deposit layers of a cellulose-based ink, which is then solidified using a mild acid. This results in a material that has the look and feel of natural wood.
Genetically engineered bacteria: Researchers at the University of Cambridge have developed a method for producing artificial wood using genetically engineered bacteria. They modified E. coli bacteria to produce a protein that can self-assemble into a cellulose-like material. This material can be molded into different shapes and has mechanical properties similar to those of natural wood.
It's important to note that both of these methods are still in the experimental stage and have not yet been commercialized. However, they show promise as potential alternatives to natural wood, which could help reduce deforestation and the environmental impact of wood-based products.
Apologies for the confusion. Here is a response to your question:
