This has put pressure on the world\u2019s hydrocarbon reserves, necessitating the need for an alternative source of plastics from renewable sources. Polylactic Acid (PLA) plastics created from renewable sources like sugarcane, corn starch, and cassava have become a great alternative for manufacturers.<\/p>\n\n\n\n<p>Unlike plastics from hydrocarbon sources, some PLA plastics are designed to be broken down under certain conditions, like in industrial composting facilities, to help lower the plastic pollution in the environment. According to the United Nations Environment Program, there has been a doubling of plastic waste every decade since 2000, with the trend expected to triple by 2060 <sup><a href=\"#ref01\" type=\"internal\" id=\"#ref01\">[1]<\/a><\/sup>.<\/p>\n\n\n\n<p>Only 9% of the 400 million tons of global plastic waste generated annually is recycled <sup><a href=\"#ref02\" type=\"internal\" id=\"#ref02\">[2]<\/a><\/sup>. The remaining 91% end up in landfills or in the ocean, which is part of the reason why more countries are banning single-use plastics. PLA plastic is moving from laboratories to production lines. This is not just an environmental symbol but also a technological fulcrum that can unlock a market worth hundreds of billions of dollars.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-basic-knowledge-of-pla\">Basic Knowledge of PLA<\/h2>\n\n\n\n<p>The process of getting PLA plastics from plants is similar to the process of getting plastics from hydrocarbon sources. The major difference is the base material. For example, in the creation of synthetic plastics from crude oil, the raw crude is distilled in a refinery to get a fraction called naphtha, which forms the base material for plastic production.<\/p>\n\n\n\n<p>In the case of PLA, starch from plants is converted into sugar, followed by the fermentation of the sugar to produce lactic acid, which forms the base material for the resulting plastic. PLA is engineered from renewable sources in the following key steps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Extraction of starch:<\/em><\/strong> PLA makers extract starch from sugarcane, corn, or any other plant substrate through wet milling (grinding and separation of the starch from other components).<\/li>\n\n\n\n<li><strong><em>Hydrolysis:<\/em><\/strong> The large molecules of the starch (polysaccharide) are converted to simple sugars (monosaccharides) like glucose through a reaction involving water and enzymes.<\/li>\n\n\n\n<li><strong><em>Fermentation:<\/em><\/strong> The resulting glucose from the hydrolysis is fermented with the help of microorganisms\u2014especially Lactobacillus species\u2014to convert the sugar into lactic acid.<\/li>\n\n\n\n<li><strong><em>Formation of Lactide:<\/em><\/strong> Lactic acid from the fermentation is converted into lactide, which is a cyclic dimer of lactic acid.<\/li>\n\n\n\n<li><strong><em>Polymerization:<\/em><\/strong> The controlled linking of the lactide molecules through polymerization forms longer chains of polylactic acid (PLA). The outcome of the polymerization is small pieces of raw PLA plastic that can be molded into different products.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-pla-plastic-key-characteristics-table\">PLA Plastic Key Characteristics Table<\/h3>\n\n\n\n<p>It has several unique characteristics that make it more desirable in the medical and food packaging industry.

Some companies and industries have been at the forefront of PLA plastic industrialization. While the use case began with simple applications like packaging, it has evolved into more technical uses like medical implants and automobiles. Here\u2019s a timeline of the three stages of industrialization that the PLA has undergone.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-2002-natureworks-first-70-000-ton-production-line\">2002: NatureWorks\u2019 first 70,000-ton production line<\/h4>\n\n\n\n<p>NatureWorks started research on how to harness the carbon dioxide molecules stored in plants to create more environmentally friendly plastic products. Their research led to the creation of Ingeo, a PLA biopolymer that was eventually used for the creation of mostly food packaging products. It was also used for food serviceware (spoon, plate, fork), textiles, packaging coatings, and 3D printing.<\/p>\n\n\n\n<p>NatureWorks is based in the USA and built the first global industrial-scale PLA production plant, which started operation in 2002 with a line capacity of 70,000 metric tons. The company doubled its production capacity in 2015. In 2023, NatureWorks announced that it had made significant progress in the construction of a PLA manufacturing facility in Nakhon Sawan Province, Thailand <sup><a href=\"#ref04\" type=\"internal\" id=\"#ref04\">[4]<\/a><\/sup>. The facility is expected to have an annual capacity of 75,000 tons of Ingeo biopolymer.<\/p>\n\n\n\n<p>NatureWorks\u2019 success inspired a similar 5,000-ton capacity PLA plastic line in China by Hisun. The company added a 10,000-ton line to the factory in 2017. The following year, Hengtian built several lactide-to-PLA fiber lines with a capacity of 10,000 tons. COFCO also installed a 10,000-ton PLA plastic plant in China in the same year.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-2016-arburg-s-medical-grade-pla-bone-screws\">2016: Arburg\u2019s medical-grade PLA bone screws<\/h4>\n\n\n\n<p>PLA plastic eventually found new and more complex industrial applications, following breakthroughs in precision injection molding and 3D printing. With Arburg\u2019s Plastic Freeforming (APF) process, medical-grade PLA bone screws were created using commercially available PLA granules.<\/p>\n\n\n\n<p>APF is an additive production method that allows the direct use of PLA granules without the added step of filament creation, which may alter the properties of the material <sup><a href=\"#ref05\" type=\"internal\" id=\"#ref05\">[5]<\/a><\/sup>. The manufacturing process jets droplets of molten plastic, layer-by-layer, to form a 3D structure.<\/p>\n\n\n\n<p>Arburg\u2019s medical-grade PLA bone screws and implants were desirable because they reduced the need for a follow-up operation to remove the materials. Instead, they degrade over time and are absorbed by the body, unlike metal implants.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-2024-heat-resistant-pla-interior-parts-for-automobiles\">2024: Heat-resistant PLA interior parts for automobiles<\/h4>\n\n\n\n<p>By 2024, heat-resistant PLA was massively adopted for the <a href=\"https:\/\/firstmold.com\/insights\/automotive-interior-parts-manufacturing-and-china-suppliers\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>creation of interior parts for automobiles<\/strong><\/a>, spearheaded by Mercedes-Benz\u2019s mass production. Although standard PLA plastic has a relatively low heat deflection temperature (around&nbsp;55\u00b0C to 60\u00b0C [131-140\u00b0F] ), it is modified with additives that improve its heat resistance and make it suitable for interior parts, like decorative accents and trim pieces.<\/p>\n\n\n\n<p>PLA plastic technological maturity has reached level 8 in different fields. At technology readiness level 8 (TRL 8), the technology demonstrates full functionality, reliability, and compliance with required regulations. The widespread use of PLA in 3D printing and end-use parts in many sectors validates its TRL 8 status\u2014and it might have reached TRL 9 in some fields.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-comparing-pla-with-pbat-and-pbs\">Comparing PLA with PBAT and PBS<\/h2>\n\n\n\n<p>PLA, Polybutylene adipate-co-terephthalate (PBAT), and Polybutylene succinate (PBS) are all forms of biodegradable plastics. Consequently, their large-scale adoption can be instrumental in the fight against plastic pollution in the environment. Although they can all be made from sustainable sources, their properties differ.<\/p>\n\n\n\n<p>PBAT is a thermoplastic polyester made up of repeating units of terephthalic acid, adipic acid, and 1,4-butanediol. Its different compound combination bestows unique properties on it. It is synthesized from the combination of adipic acid, terephthalic acid, and butylene glycol, and is particularly known for its flexibility and high elongation at break. It is mostly used in food packaging.<\/p>\n\n\n\n<p>PBS is synthesized from succinic acid and 1,4-butanediol. In addition to being biodegradable, it is highly resistant to heat and compatible with other biodegradable polymers. Its properties are closely related to what is obtainable with isotactic polypropylene and high-density polyethylene, which makes it a great choice for broad applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-comparison-of-the-properties-of-pla-pbat-and-pbs\">Comparison of the properties of PLA, PBAT, and PBS<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Properties<\/th><th>PLA plastic<\/th><th>PBAT plastic<\/th><th>PBS plastic<\/th><\/tr><tr><td>Biodegradability<\/td><td>compostable in an industrial composting facility under specific conditions<\/td><td>Because of the presence of butylene adipate, it is fully biodegradable when composted<\/td><td>Microorganisms can break it down into water and carbon dioxide<\/td><\/tr><tr><td>Melting temperature<\/td><td>302<sup>o<\/sup>F to 356<sup>o<\/sup>F<\/td><td>230<sup>o<\/sup>F to 266<sup>o<\/sup>F<\/td><td>212<sup>o<\/sup>F to 266<sup>o<\/sup>F<\/td><\/tr><tr><td>Tensile strength<\/td><td>50 to 70 MPa<\/td><td>17 to 24 MPa (can be increased to 47 MPa by adding lignin-TiO2 nanoparticles)<\/td><td>30 to 50 MPa<\/td><\/tr><tr><td>Flexibility<\/td><td>Generally rigid and brittle (but flexibility can be increased with plasticizers)<\/td><td>Stretches significantly before breaking<\/td><td>Has good flexibility<\/td><\/tr><tr><td>Cost<\/td><td>Moderate to low<\/td><td>Moderate<\/td><td>Moderate<\/td><\/tr><tr><td>Application &nbsp; &nbsp;<\/td><td>3D printing, food packaging, medical implants, textiles, and automotive<\/td><td>Mulch films, food packaging, fabrics, and temporary implants<\/td><td>Agricultural films, food packaging, and medical devices<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>PLA, PBAT, and PBS are inherently hydrophobic due to the presence of methyl groups (CH3). In simple words, these renewable plastics have moderate water absorption and wicking properties compared to Polyethylene Tetraphthalate (PET). This property makes renewable plastics a better choice for sportswear compared to PET.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-popular-applications-of-pla-plastic\">Popular Applications of PLA Plastic<\/h2>\n\n\n\n<p>Two to three decades ago, it cost around $200 to make a pound of PLA, a major setback on its path to industrialization. With the help of innovative technologies, you can get a pound today for less than $2. With the cost constraints now behind us, the door has opened for mass adoption in various industries. Today, the manufacturers that have adopted PLA the most are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Indoor 3D printing of parts<\/li>\n\n\n\n<li>Medical implants<\/li>\n\n\n\n<li>Fashion<\/li>\n\n\n\n<li>Packaging of food and drinks<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-pla-plastic-use-in-3d-printing\">PLA Plastic Use in 3D Printing<\/h3>\n\n\n\n<p>When it comes to 3D printing, PLA filament is a widely accepted option because of its low melting point compared to other filaments, which makes it easy to use. The low melting point speeds up the printing process, reducing warping and energy requirements. Also, during the printing process, PLA filament releases lactide, which is generally considered non-toxic fume. Therefore, the use of PLA filament for 3D printing is safe for indoor use. Other advantages of PLA in 3D printing include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Emits a sweet smell during printing, unlike the foul fumes emitted by some materials.<\/li>\n\n\n\n<li>The printed parts can be solvent welded, which makes assembly of the parts easier.<\/li>\n\n\n\n<li>Available in a vast color option.<\/li>\n\n\n\n<li>It can be blended with other materials to create different properties.<\/li>\n\n\n\n<li>Printing with PLA plastic has good dimensional accuracy that closely matches the intended dimension.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-benefits-of-pla-use-for-medical-implant\">Benefits of PLA Use for Medical Implant<\/h3>\n\n\n\n<p>PLA enjoyed a better reception in the medical field because of its inherent properties. For example, it has good biocompatibility as an implant, meaning it doesn\u2019t elicit adverse reactions when implanted in the human body. Bio-incompatibility can lead to inflammation and other adverse reactions that could be deadly. Consequently, it is used for surgical implants, tissue engineering scaffolds, and drug delivery systems.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It reduces the risk of infection and follow-up operations because it degrades naturally.<\/li>\n\n\n\n<li>The rate of degradation can be controlled by blending PLA with other materials.<\/li>\n\n\n\n<li>PLA plastic strength and stiffness can be manipulated to make different types of implants, like a bone screw.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-pla-plastic-gains-in-fashion\">PLA Plastic Gains in Fashion<\/h3>\n\n\n\n<p>The fashion industry generates around 92 million tons of textile waste globally every year <sup><a href=\"#ref06\" type=\"internal\" id=\"#ref06\">[6]<\/a><\/sup>. The bulk of this waste ends up in landfills, while the rest ends up in water bodies. The use of PLA helps to lower the textile burden in the environment because it degrades over time. Other benefits of using PLA in the fashion industry include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Breathability of PLA fabrics allows the circulation of air, which keeps the wearer cooler and comfortable.<\/li>\n\n\n\n<li>They have a soft, comfortable feel on the body.<\/li>\n\n\n\n<li>PLA fiber offers adequate&nbsp;strength for daily wear while offering biodegradability.<\/li>\n\n\n\n<li>PLA fabric can hold color and resist fading from washing or drying in the sun.<\/li>\n\n\n\n<li>Their hypoallergenic property makes them suitable for people with sensitive skin.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pla-processing-technologies\">PLA Processing Technologies<\/h2>\n\n\n\n<p>PLA plastic is compatible with the majority of the available plastic processing technologies with minimal modifications.&nbsp;For example, PLA is easily formed into different shapes using injection molding. Granules of PLA can also be molten and forced through a die to form films and sheets. It can also be processed through blow molding to create bottles and containers.<\/p>\n\n\n\n<p>Since PLA can absorb water, it is always important to dry it before using it with any of the molding technologies. Using a wet PLA filament on a 3D printer, for example, can lead to performance issues and print defects. During printing, the water absorbed by the filament will turn to steam, leading to popping sounds and inconsistent extrusion or bubbly surface finish. In extreme cases, the filament expands due to steam and clogs the nozzle, leading to total print failure. Some of the ways for drying PLA filament include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Drying with oven:<\/em><\/strong> Preheat the oven to around 110\u00b0F to 120\u00b0F. Place the filament in it for 4 to 6 hours. Always keep the oven well below the melting temperature of PLA.<\/li>\n\n\n\n<li><strong><em>Using a filament dryer:<\/em><\/strong> Follow the instructions that came with the dryer<\/li>\n\n\n\n<li><strong><em>Desiccator and Ziploc:<\/em> <\/strong>For less severe moisture, place the PLA filament in a Ziploc with some desiccant packets and leave it for several hours<\/li>\n\n\n\n<li><strong><em>Food dehydrator:<\/em><\/strong> Since PLA is a food-grade plastic, you can place it in a food dehydrator with adjustable temperature and dry it there<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-pla-plastic-injection-molding-parameters-and-equipment-modification\">PLA Plastic Injection Molding Parameters and Equipment Modification<\/h3>\n\n\n\n<p>The good news for manufacturers who want to switch from synthetic plastic to PLA plastic for their products is that no major tooling modification may be required. The major alterations often involve adjusting the flow parameters like temperature, pressure, injection speed, cooling, and cycle time to accommodate the thermal sensitivity of the material.<\/p>\n\n\n\n<p>Where necessary, the manufacturer may need to incorporate additives to get the desired properties. In a few cases, the mold design may need to be optimized to improve the quality of the manufactured part. Common transformations include rethinking the gate design, altering wall thickness, and adding draft angles. Optimizing the cooling system is vital to prevent warpage and shrinkage.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Injection molding parameter<\/th><th>Recommended optimal<\/th><\/tr><tr><td>Melting temperature<\/td><td>356\u00b0F to 428\u00b0F, and up to 464\u00b0F for some grades (sufficient temperature is necessary to prevent premature solidification)<\/td><\/tr><tr><td>Mold temperature<\/td><td>180\u00b0F to 220\u00b0F, depending on desired part properties and geometry<\/td><\/tr><tr><td>Injection pressure<\/td><td>Requires moderate injection pressure between 55 MPa and 110 MPa<\/td><\/tr><tr><td>Injection speed<\/td><td>Usually within the range of 150 mm\/s to 300 mm\/s for proper filling<\/td><\/tr><tr><td>Cooling time<\/td><td>Requires a longer cooling time because of the slow crystallization rate.

This may involve physical modification, chemical modification, or the use of additives. Here is a list of the different techniques for PLA plastic modification.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-chemical-modification\">Chemical modification<\/h4>\n\n\n\n<p>There are different options here, but the choice will depend on the property that the manufacturer wants to confer on the product. The common techniques are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Copolymerization:<\/em><\/strong> The blending of PLA with polycaprolactone or other monomers to improve properties like degradation rate, flexibility, and thermal stability.<\/li>\n\n\n\n<li><strong><em>Chain extension:<\/em><\/strong> Increasing the molecular weight by adding molecules like maleic anhydride or epoxy-functionalized compounds. This improves melt strength.<\/li>\n\n\n\n<li><strong><em>Grafting:<\/em><\/strong> The process of giving PLA hydrophobicity or other desirable properties by attaching other polymers or molecules to its backbone.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-physical-modification\">Physical modification<\/h4>\n\n\n\n<p>This change often happens on the surface level without involving any chemical change to the PLA molecules. They are also used to give the desired properties to the material. For example, it can be combined with cellulose or starch in a process called blending to improve its flexibility and biodegradability. Other physical modifications are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Nucleation:<\/em><\/strong> Enhancing crystallization with the addition of nucleating agents.<\/li>\n\n\n\n<li><strong><em>Annealing:<\/em><\/strong> Applying heat treatment to the PLA part after processing to improve crystallinity.<\/li>\n\n\n\n<li><strong><em>Surface treatment:<\/em><\/strong> Coating the surface with a desirable compound to enhance wettability, biocompatibility, or adhesion.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-fillers-and-additives\">Fillers and Additives<\/h4>\n\n\n\n<p>One of the drawbacks of using PLA is its low impact resistance. That can be improved with the addition of rubber or other polymers. Likewise, the incorporation of glass fibers, biofibers, nanoclays, and other similar materials can improve the thermal stability and other characteristics of PLA plastic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-frontier-technological-breakthrough-directions\">Frontier technological breakthrough directions<\/h3>\n\n\n\n<p>Frontier technologies like AI have played a significant role in PLA plastic production. With AI technologies, manufacturers can optimize different production stages and accurately simulate how different polymers can impact PLA\u2019s properties. Consequently, AI helps to fast-track the development of new PLA designs, improve the efficiency of existing formulations, and make the production of PLA more sustainable.<\/p>\n\n\n\n<p>Automation of production systems with the help of AI now helps manufacturers to monitor and optimize the PLA production process in real-time. The systems can automatically adjust molding parameters like temperature, injection pressure, flow speed, and so on to increase efficiency and minimize waste and defects.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pla-market\">PLA Market<\/h2>\n\n\n\n<p>The global PLA plastics market has grown significantly in the last two decades. The upward trend is expected to continue in the future, partly driven by environmental regulations to curb plastic pollution. As of 2023, more than 130 countries around the globe had banned or partially restricted single-use plastics, including plastic bags, straws, food containers, and so on <sup><a href=\"#ref07\" type=\"internal\" id=\"#ref07\">[7]<\/a><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-scale-and-growth\">Scale and Growth<\/h3>\n\n\n\n<p>Mordor Intelligence estimates that the PLA plastic market size in 2025 is 2.59 million tons, and it is projected to reach 6.45 million tons by 2030 at a cumulative annual growth rate (CAGR) of over 20% <sup><a href=\"#ref08\" type=\"internal\" id=\"#ref08\">[8]<\/a><\/sup>.<\/p>\n\n\n\n<p>The European Bio-Polylactic Acid Organization said PLA was the most produced biodegradable plastic, with the capacity hitting 675.8 kilotons in 2023. The global PLA market was valued at least $1.5 billion in 2023, but MarketsandMarkets expects that number to reach $3.3 billion by 2028 <sup><a href=\"#ref09\" type=\"internal\" id=\"#ref09\">[9]<\/a><\/sup>. Europe has the largest PLA market, influenced by increasing demand from sustainable packaging and strict environmental regulations.<\/p>\n\n\n\n<p>PLA injection molding has moved beyond R&amp;D and entered large-scale application, thanks to innovations that have now made the process cost-effective. In November 2024, Futerro set up the first vertically integrated biorefinery in Europe. Located in Normandy, the facility produces and recycles PLA. In many countries, PLA packages have replaced banned single-use plastics.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-challenges-and-future\">Challenges and Future<\/h2>\n\n\n\n<p>Out of all the different available biodegradable polymers, PLA plastic and PBAT plastic are the most commercialized due to their large availability and processing feasibility. The main pain point that stands in the path of biodegradable plastic commercialization is the cost of production.<\/p>\n\n\n\n<p>Depending on the region where you source your PLA from, the price can vary from $2.33 per kg (Northeast Asia) to $2.86 per kg (Europe), according to Business AnalystIQ <sup><a href=\"#ref10\" type=\"internal\" id=\"#ref10\">[10]<\/a><\/sup>. Although the price has reduced significantly over the years, it is still more expensive compared to polypropylene plastic, which can be purchased for $1.03 per kg in Northeast Asia or $1.58 per kg in Europe.<\/p>\n\n\n\n<p>To offset the cost and boost performance, custom blends of PLA plastic, like mixing PLA and TPS or PLA and PBAT, will likely be favored in the future. This includes blending PLA with natural fibers and other polymers to produce composites with better properties for specific applications.<\/p>\n\n\n\n<p>Several PLA plastic makers have a 2025 \u2013 2030 roadmap that focuses on improving material properties, enhancing production efficiency, and expanding applications. There is growing research on integrating 3D printing with injection molding <sup><a href=\"#ref11\" type=\"internal\" id=\"#ref11\">[11]<\/a><\/sup>.<\/p>\n\n\n\n<p>It is believed that combining both methods into a single production system will lower the limitations of their individual use cases. For example, 3D-printed molds can lower the high initial tooling cost and extended lead times facing injection molding. With the possibility of AI technology, further automation can be achieved with a 3D printing-injection molding PLA hybrid.<\/p>\n\n\n\n<p><em>Tips: Learn more about the other plastics<\/em><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/abs-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>ABS<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pe-plastic\/\"><strong>PE<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pvc-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PVC<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pp-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PP<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pa-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PA<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pc-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PC<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/ps-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PS<\/strong><\/a><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pom-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>POM<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pmma-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PMMA<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/peek-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PEEK<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pbt-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PBT<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/psu-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PSU<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pps-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PPS<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/san-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>AS<\/strong><\/a><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/ppo-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PPO<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/ppa-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PPA<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/tpu-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>TPU<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/tpe-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>TPE<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/firstmold.com\/guides\/pet-plastic\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>PET<\/strong><\/a><\/td><td class=\"has-text-align-center\" data-align=\"center\"><\/td><td class=\"has-text-align-center\" data-align=\"center\"><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-references\">References<\/h2>\n\n\n\n<p id=\"ref01\">[1] United Nations Environment Programme.
