Perfect polymers — polymers that balance physical and environmental properties — do not exist, but polybutylene terephthalate (PBAT) is closer to perfection than many polymers.
For decades, manufacturers of synthetic polymers have failed to prevent their products from eventually entering landfills and oceans, and they are now under pressure to take responsibility. Many people are redoubling their efforts to promote recycling to avoid criticism. Other companies are trying to solve the waste problem by investing in biodegradable bio based plastics, such as polylactic acid (PLA) and polyhydroxyalkanes (PHA), hoping that natural degradation can reduce at least some waste.
However, both recycling and biopolymers face obstacles. For example, despite years of efforts, the plastic recovery rate in the United States is still less than 10%. However, it is difficult for bio based polymers – usually fermentation products – to achieve the same performance and production scale as the mature synthetic polymers they are to replace.
PBAT combines some beneficial properties of synthetic polymers and bio based polymers. It comes from common petrochemical products – purified terephthalic acid (PTA), butanediol and adipic acid, but it is biodegradable. As a synthetic polymer, it can be easily produced on a large scale, and it has the physical properties required to manufacture flexible films, which can be comparable to the films of traditional plastics.
Interest in PBAT is rising. Old brand manufacturers such as BASF in Germany and novamont in Italy have seen an increase in demand after decades of market cultivation. More than half of Asian manufacturers have joined them. With the promotion of sustainable development by regional governments, they expect the business of this polymer to be booming.
Marc Verbruggen, a former CEO of NatureWorks, a PLA manufacturer, is now an independent consultant. He believes that PBAT is “the cheapest and easiest way to manufacture bioplastics products”. He believes that PBAT is becoming an excellent flexible bioplastics, It is ahead of competitors such as polybutylene succinate (PBS) and PHA, and it may become one of the two most important biodegradable plastics as a whole, keeping pace with PLA. He said PLA is becoming the main product for rigid applications.
Ramani Narayan, a professor of chemical engineering at Michigan State University, said that the main selling point of PBAT — its biodegradability — comes from ester bonding rather than carbon carbon bonds like non degradable polymers such as polyethylene. Ester bonds are susceptible to hydrolysis and enzymes.
For example, polylactic acid and PHA are polyesters that degrade when their ester connections are destroyed. But the most common polyester, polyethylene terephthalate (PET), used in fibers and mineral water bottles, is less likely to decompose. This is because the aromatic rings in its backbone come from PTA. According to Narayan, these rings give structural properties and make pet hydrophobic. He said: “water is not easy to enter. It slows down the whole hydrolysis process.”
Some ingenious chemical reactions led scientists to invent PBAT in the 1990s as a bridge between aliphatic and aromatic polyesters.
BASF produces polybutylene terephthalate (PBT), a polyester made of butanediol. The company’s researchers are looking for a biodegradable polymer that they can easily produce. They use aliphatic dibasic acids to replace some PTA in PBT. In this way, the aromatic part of the polymer is separated so that it can be biodegradable. At the same time, enough PTA is left to make the polymer biodegradable Trustworthy physical properties.
Narayan believes that the biodegradability of PBAT is better than that of PLA, which needs industrial compost to decompose. However, it can not be compared with the commercially available PHA, which can be biodegradable under environmental conditions and even in the marine environment.
Experts most often compare the physical properties of PBAT with low-density polyethylene, an elastic polymer used to make films, such as garbage bags.
PBAT is often mixed with polylactic acid, a rigid polymer with polystyrene like properties that provides hardness. BASF’s ecovio brand is based on this mixture. For example, Verbruggen says compostable shopping bags are usually 85% PBAT and 15% PLA.
Novamont added another dimension to the formula. The company mixes PBAT and other biodegradable aliphatic aromatic polyesters with starch to create resins for specific applications.
Stefano facco, the company’s new business development manager, said: “over the past 30 years, novamont has been committed to solving applications where degradability adds value to the product itself.
A big market for PBAT is mulch, which is spread around crops to prevent weeds and help maintain moisture. When polyethylene films are used, they must be pulled up and often buried. However, biodegradable films can be cultivated directly into the soil.
Another big market is compostable garbage bags, which are used for catering services and household collection of food and yard waste. Bags from companies such as biobag, which novamont recently acquired, have been sold at retailers for many years.
Joerg auffermann, head of the global business development team of BASF biopolymers, said: “the main ecological benefits of Compostable Plastics come from their service life, because these products help transfer food waste from landfills or incinerators to organic recycling.
Over the years, biodegradable polyester industry has entered applications other than film. For example, in 2013, the Swiss coffee company launched a coffee capsule made of BASF’s ecovio resin.
An emerging market for novamont materials is biodegradable tableware, which can be composted with other organics. Facco said the tableware has started in Europe and other places that have passed regulations restricting the use of disposable plastics.
As more environment driven growth is expected, new Asian PBAT participants are entering the market. In Korea, LG Chemical is building a PBAT plant with an annual output of 50000 tons, which will open in 2024 as part of the $2.2 billion sustainable investment plan of Ruishan city. Sk geo centric (formerly known as SK global chemistry) and Kolon industries are cooperating to build a 50000 ton PBAT plant in Seoul. Kolon industries, a nylon and polyester manufacturer, provides production technology, while SK provides raw materials.
PBAT in the Chinese market is the most popular. Okchem, a Chinese chemical distributor, predicts that China’s PBAT production will rise from 150000 tons in 2020 to about 400000 tons in 2022.
Some Chinese enterprises are increasing their investment in PBAT. Hengli Petrochemical’s new biodegradable material project with an annual output of 450000 tons, with a total investment of 1.8 billion yuan, is located in Hengli (Changxing Island, Dalian) Industrial Park. Using independently developed process technology and formula, relying on the raw materials and supporting advantages of the industrial park, it mainly constructs two major projects: 150000 T / a PBS biodegradable plastics and 300000 t / a PBAT biodegradable plastics.
Verbruggen believes that there are many driving forces for investment. First, all types of biopolymers have recently experienced an increase in demand. The supply is tight, so the prices of PBAT and PLA are very high.
In addition, Verbruggen said that the Chinese government has been promoting China’s “great development” in bioplastics. Earlier this year, the Chinese government passed a law banning the use of non degradable shopping bags, straws and tableware.
Verbruggen said that the PBAT market is attractive to Chinese chemical manufacturers. This technology is not complicated, especially for companies with experience in polyester.
In contrast, polylactic acid is capital intensive. Before manufacturing this polymer, the company needs to ferment lactic acid from an adequate sugar source. Verbruggen pointed out that China has a “sugar deficit” and needs to import carbohydrates. “China is not necessarily a good place to build a lot of capacity,” he said.
Existing PBDE manufacturers have been keeping up with new players in Asia. In 2018, novamont completed a project to transform a PET plant in patrica, Italy, to produce degradable polyester. The project doubled the output of biodegradable polyester to 100000 tons per year.
In 2016, novamont opened a plant to produce butanediol from sugar using the fermentation technology developed by genomatica. The plant with an annual output of 30000 tons is located in Italy and is the only similar plant in the world.
According to facco, the new Asian PBAT manufacturers may produce a limited number of commercial polymer grades for large-scale applications. “It’s not complicated.” He said. In contrast, novamont will maintain its strategy of serving the professional market. “This is where we have some knowledge and are good for the market,” he said
BASF is responding to the trend of PBAT construction in Asia and participating in the construction of a new factory in China. The company licensed its PBAT technology to Tongcheng Xincai, a Chinese company, which plans to build a production plant with a capacity of 60000 tons / year in Shanghai by 2022.
Auffermann said: “with the upcoming new laws and regulations guiding the application of bioplastic materials in packaging, mulching and bags, it is expected that the positive market development will continue. The new plant will enable BASF to meet the growing demand in the region locally.”
In other words, BASF, which started producing PBAT 25 years ago, is now keeping up with the upsurge of new business because this polymer is becoming a mainstream material.

Biodegradable mulch films are an alternative to polyethylene films used in agriculture for weed control, improving crop productivity. This change could minimize the residue production and costs related to the final disposal.

Soil biodegradable mulch films composed of the polyester polybutylene adipate-co-terephthalate (PBAT) are being increasingly used in agriculture. Analytical methods to quantify PBAT in field soils are needed to assess its soil occurrence and fate. Here, we report an analytical method for PBAT in soils that couples Soxhlet extraction or accelerated solvent extraction (ASE) with quantitative protonnuclear magnetic resonance (q-1H NMR) spectroscopy detection. The 1H NMR peak areas of aromatic PBAT protons increased linearly with PBAT concentrations dissolved in deuterated chloroform (CDCl3), demonstrating accurate quantitation of PBAT by q-1H NMR. Spike-recovery experiments involving PBAT addition to model sorbents and soils showed increased PBAT extraction efficiencies into chloroform (CHCl3) with methanol (MeOH) as cosolvent, consistent with MeOH competitively displacing PBAT from H-bond donating sites on mineral surfaces. Systematic variations in solvent composition and temperatures in ASE revealed quantitative PBAT extraction from soil with 90/10 volume % CHCl3/MeOH at 110-120 °C. Both Soxhlet extraction and ASE resulted in the complete recovery of PBAT added to a total of seven agricultural soils covering a range of physicochemical properties, independent of whether PBAT was added to soils dissolved in CHCl3, as film, or as particles. Recovery was also complete for PBAT added to soil in the form of a commercial soil biodegradable mulch film with coextractable polylactic acid (PLA). The presented analytical method enables accurate quantification and biodegradation monitoring of PBAT in agricultural field soils.

Global Mulch Films Industry

Weathering the current pandemic and the looming recession, the global market for Mulch Films is projected to reach US$5. 1 billion by 2027. Intricately linked to food security, the agriculture industry is expected to buck the economic pressures posed by the COVID-19 pandemic.

Mulches are applied to the surface of the soil, and around flower beds, trees, and paths, for preventing soil erosion from slopes, and in growing areas for vegetable and flower crops. Layers of mulch are normally applied 2 inches or more deep. Depending on their intended use, mulches are applied at several times during the year. Towards the start of the cultivation season, mulches are initially applied for warming the soil by preventing loss of heat during the night. The prevention of heat loss, while enabling early transplanting and seeding of certain crops, encourages faster growth. Plastic mulch, which is used by large-scale commercial farms, is spread across the field either in the form a standalone plastic mulch layer or with the help of a tractor. Plastic mulch generally forms a part of a high-end mechanical process, in which raised beds covered with plastic are created, and seedlings transplanted into the soil through holes in made the plastic. Since the plastic mulch is impervious to water, drip tapes are laid under the mulch for providing drip irrigation. A key trend in the market is the growing preference for biodegradable mulch film. With agriculture contributing to over 20. 4% of global man made greenhouse gas (GHG) emissions worldwide, pressure is mounting on the agricultural sector to minimize its role in climate change. Biodegradable mulch offers several benefits such as eco-friendliness and sustainability when compared to polyethylene (PE) mulch; least impact on soil biological and biogeochemical processes; reduced risk of microbial community changes and functioning via microclimate modification; elimination of labor costs and landfill disposal fees associated with removing and disposing PE mulch; lower environmental burden when compared to on-farm burning and stockpiling issues associated with PE mulches; cost effective, easy application, zero toxic residues in the soil and ensures agro ecosystem sustainability.

June 1, 2018 is the tenth year for China to implement the plastic restriction order. Can you tell me which countries in the world have implemented the plastic restriction order?
At present, more than 40 countries and regions have made regulations on the use of plastic bags, including three kinds of policies: prohibition, partial prohibition and restricted use.
Plastic reduction policies in Europe and the United States continue to strengthen. The European Union recently announced that it will recycle or reuse plastic packaging by 2030, but most European countries are only at the level of consumers’ voluntary reduction. France’s plastic restriction order was upgraded at the beginning of this year, and all cosmetics containing plastic particles will be taken off the shelves. From 2020, household plastic cotton swabs and disposable plastic tableware will also be banned. At the beginning of this year, the UK proposed to ban plastic bags, bottles, plastic straws and other products within 25 years. In the United States, only California has banned plastic bags, while other cities need to pay for paper or plastic bags.
At present, more than 12 of the 54 countries in Africa have introduced plastic limit policies. Eritrean government banned plastic bags as early as 2005. Other countries include Tanzania (2006), Uganda (2007), Rwanda (2008), Mauritania (2013), Morocco (2016), Senegal (2016), Somaliland (2017), Tanzania (2017) and Kenya (2017). If these countries want to completely ban plastic bags, or ban the manufacture, sale and use of plastic bags, the punishment will be stronger 。
The Asian plastic restriction order is quite effective. In 2002, Bangladesh became the first country in the world to ban plastic bags. Mumbai, India, banned the use of plastic bags less than 0.05mm in thickness in 2016, and Sri Lanka also banned plastic bags, plastic plates and plastic cups. The plastic restriction policies of Southeast Asian countries are different. The government of Rangoon, the capital of Myanmar, banned the manufacture, sale and storage of plastic bags; Malaysia announced in 2017 that the federal region banned the use of general plastic bags. Other regions, such as Japan, have announced that all retail stores will ban the provision of free plastic bags from 2020. In 2008, China banned the provision of free plastic bags, the manufacture, sale and use of plastic bags less than 0.025mm in thickness. The South Korean government decided in 2018 that large supermarkets would ban disposable plastic bags.

A significantly growing interest is to design new biodegradable polymers in order to solve fossil resources and environmental pollution problems associated with conventional plastics. A kind of new biodegradable polymers, aliphatic–aromatic co-polyesters have been researched widely and developed rapidly in recent years, since that can combine excellent biodegradability provided from aliphatic polyesters and good properties from aromatic polyesters. Out of which, poly (butylene-adipate-co-terephthalate) (PBAT) shows the most importance. PBAT has been commercialized by polycondensation reaction of butanediol (BDO), adipic acid (AA) and terephthalic acid (PTA) using general polyester manufacturing technology. And it has been considered to have desirable properties and competitive costs to be applied in many fields. Therefore, this review aims to present an overview on the synthesis, properties and applications of PBAT.

Is PBAT toxic? While PBAT is incredibly biodegradable and will decompose in home compost leaving no toxic residues, it is currently partly derived from petrochemicals, yip, oil. … Interestingly, it is PBAT that is added to make the product degrade quickly enough to meet the home compostability criteria.

What is PBAT and PLA? Biodegradable polymers as poly(lactic acid) (PLA) and poly(butylene adipate-co-terephthalate) (PBAT) are thermoplastics which can be processed using the most conventional polymer processing methods. PLA is high in strength and modulus but brittle, while PBAT is flexible and tough.

Is PBAT biodegradable? Poly(butylene adipate-co-terephthalate) (PBAT) is a well-known biodegradable plastic. It is a flexible material, and has a high elongation at break, as well as good hydrophilic and processing properties.

What is PBAT material? PBAT (polybutyrate adipate terephthalate) is a biodegradable random copolymer. The co-polyester of adipic acid, 1,4-butanediol and dimethyl terephthalate is available commercially as resin and as compound with PLA or starch. As a “drop-in” polymer, PBAT resembles LDPE in its properties.

In the 21st century, as one of most important materials, conventional plastics have been developed rapidly and utilized widely in varieties of fields because of their excellent comprehensive properties and low costs. Unfortunately, most of these conventional plastics, such as polyethylene (PE), polypropylene (PP) and polystyrene (PS) etc., come from petroleum origin and their wastes cannot be degraded. So the increase in the production and consumption of conventional plastics, as a consequence, results in the increase of oil consumption and serious environmental pollution. Fossil resources and environmental pollution, as the major problems caused by conventional plastics, should be solved for sustainable development in future.

The overall strategy to solve these difficult problems on fossil resources and environmental pollution should be through recycling wasted conventional plastics and using biodegradable plastics together. The serious problems could not be solved by means of conventional plastic recycling alone, because it is not always possible to recover all the used plastics. A considerable amount of wasted plastics are eventually destined to be burnt or buried in land during recycling processes of wasted plastics, whether physical or chemical recycling. In such situation, it is one effective way and beneficial supplement for solving these plastic problems to use biodegradable plastics, compared to plastic recycling. A biodegradable plastic is one that undergoes decomposition due to the action of naturally occurring microorganisms such as fungi, algae and bacteria. Take these into consideration, the necessity of biodegradable plastics can be easily understood that their wastes can be recovered by microorganisms under natural environment. In fact, biodegradable plastics have become increasingly popular all over the world, because biodegradable plastics have been put into effect in solving these plastic problems with their rapid developments and wide applications in recent years.

The market for biodegradable plastics has also shown strong growth during the last two decades. In 2005 the global biodegradable plastics market tonnage was estimated at 94,800 tones and in 2010 the market reached the 214,400 tones, which represents a compound annual growth rate of 17.7% during the period 2005–2010. Packaging (including rigid and flexible packaging, paper coating, and foodservice) consumes about the 39% of the total biodegradable polymer market volumes, followed by loose-fill packaging (about 24%), bags and sacks (21%), fibers (9%), and others (7%). Consequently, there is a strong demand to design and improve biodegradable plastics that are not only biodegradable but also meet the requirements of expected material properties.

To solve the environmental problems and meet the market demand, there is a growing interest in designing new biodegradable polymers which are the foundation of biodegradable plastics. During developing biodegradable polymers, polyesters are a particularly interesting group of polymers.On one hand, aliphatic polyesters have been shown to be easily biodegradable because of their ester bonds in the soft chain, which are sensitive to hydrolysis. Unfortunately, aliphatic polyesters like poly-caprolactone (PCL) and poly-β-hydroxybutyrate (PHB), show poor mechanical and thermal properties. On the other hand, aromatic polyesters like Polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), exhibit very good physical properties but strong resistance to attack by microorganisms. Therefore, in order to design new polyesters having both satisfactory mechanical properties and desirable biodegradability, some aliphatic-aromatic co-polyesters consisting of aliphatic and aromatic units have been synthesized and researched.

Among numerous aliphatic-aromatic co-polyesters, the most promising and popular one with potential development prospects in a wide range of applications is poly (butylene adipate-co-terephthalate) (PBAT), obtained by poly-condensation between butanediol (BDO), adipic acid (AA) and terephthalic acid (PTA). It has been turn out to be the most appropriate combination, regarding excellent properties and good biodegradability. The commercially available aliphatic-aromatic co-polyester PBAT is list in Table 1. Therefore, the scope of this review is a comprehensive summary of currently available results about the synthesis, properties and applications of PBAT.

Major commercially available Co-polyester PBAT.

Mechanical properties

PBAT shows not only good biodegradability due to the aliphatic unit in the molecule chain, but also excellent mechanical property thanks to the aromatic unit in the molecule chain. Compared to most biodegradable polyesters such as poly (lactic Acid) (PLA) and poly (butylene-co-succinate) (PBS), the mechanical properties of PBAT show more flexible, and are similar to those of low-density PE (LDPE). These mechanical properties make PBAT a very promising biodegradable material for a wide range of potential applications.

The mechanical properties of PBAT.

Application of PBAT

For about past two decades, vast amount of research is being carried in the field of PBAT, which illustrates its significance. However, research and development is just part of a product life cycle. The real product starts when the sciences being applied to a specific application. Thus, the product process introduces a new material into the market. Now the development state of PBAT is under more and more applications into the market. Many products based on PBAT have been applied into many fields such as shopping bags, garbage bags, cutlery and mulch film etc. And out of which, two applications is select to be introduce in the details in this text, one is packaging aimed to the recent market, and the other is mulch film aimed to the future market.

Packaging

Conventional plastic packaging is widely used in a number of consumer goods and garbage collection applications due to its good properties and low cost compared to other packaging materials. In past ten year, around 14 million tons of conventional plastic packaging waste was generated each year, out of which only 1.6 million tons was recovered through recycling and the rest of which ended up in landfills. In efforts to reduce conventional plastic packaging, one of the recovery techniques is composting using the biodegradation process. As a result, a number of biodegradable PBAT-based materials are being commercialized that are compostable. Packaging based on these materials has currently gained great attention in many disciplines because of unique properties when compared to conventional plastic materials. There are a number of commercially available compostable PBAT-based materials that could be further processed to make a package for desired applications. Some of the notable companies that have been developing PBAT-based materials are BASF, Novamont, Junyuan, BIOTECH and KINGFA etc. As one of the world leaders in biodegradable plastics, KINGFA has developed several compostable materials based on PBAT, starch and PLA etc. These materials have found several applications in packaging especially in shopping bags, compost bags etc., as exhibit in. The shopping bags supervised by KINGFA based on Starch-PBAT blends have been widely used in high-level supermarkets in China, which has become a model for the application of biodegradable plastics in China.

Some applications of PBAT based products

Mulch film

Modern agriculture heavily relies on the use of conventional plastic mulch films, because these films can raise crop yields through elevating soil temperatures, conserving soil moisture, controlling weed growth and providing protection against severe weather and pests. The global agricultural film market is predicted to reach an annual volume of 7.5 million tons by 2021, and China uses the most PE mulch film with 1.5 million tons annually. After these PE mulch films have been used up, it is hard to recovery them from agricultural fields completely, due to PE film embrittlement and fragmentation caused by weathering, particularly when thin films are used. Residual PE films enter and subsequently accumulate in agricultural soils, as results, which decrease soil productivity by blocking water infiltration, impeding soil gas exchange, constraining root growth, and altering soil microbial community structures. A promising approach to overcome the accumulation of residual PE mulch films in soils is to replace the conventional with biodegradable mulch films composed of polymers designed to be degradable by soil microorganisms. Biodegradable mulch films placed in the soil are susceptible to ageing and degradation during their useful lifetime, so they need to have some specific properties. PBAT based mulch films have been developed by KINGFA to meet agricultural requirements, as exhibit in. When applied in soil, PBAT based mulch films can be little affect by water, high temperatures and UV radiation during their useful lifetime and can be biodegradable completely after their useful lifetime. The agricultural films manufactured by KINGFA and Junyuan based on PBAT/PLA/Nano-particles composites have been applied and achieved positive results in many regions and crops in China, which build a good foundation for the further developments in China.

Conclusions

The indiscriminate use of conventional plastics has brought about significant environmental problems, which has led to increased interest in biodegradable plastics, especially PBAT based biodegradable plastics that can offer a number of benefits in environmental conservation due to their biodegradability. So the important issues about PBAT such as synthesis, properties, composites and applications are discussed in this review. PBAT can be easily synthesized using conventional polyester manufacturing technology, which make it can be possible to obtain sufficient capacity for PBAT in a short term. Since PBAT shows not only good biodegradability but also excellent properties, PBAT can be applied in many fields, especially in package and mulch film application. So PBAT is considered to be one of the most promising biodegradable polyesters.

In the future, conversion of biomass components into PBAT is one of the promising and economical techniques to overcome fossil fuel crisis. Firstly, bio-based BDO has been obtained through industrial biological fermentation to replace of petrochemical BDO in PBAT directly. Secondly, sebacic acid, as a substitute of AA, coming from castor oil has been used as monomer to prepare poly (butylene sebacinate-co-butyleneterephthalate) (PBSeT) co-polyesters. Finally, 2, 5-furandicarboxylic acid (FDCA) has been regarded as one of the most high-potential bio-based aromatic monomers. It is a perfect bio-based alternative to the petroleum-based PTA. Hence, it is foreseeable that whole bio-based aliphatic-aromatic co-polyesters will be formed in a few years.

PBAT has excellent mechanical performance, almost same as PP and ABS, good heat resistance and outstanding process ability allows it to be variously processed on conventional blown film plants.
Our PBAT is completely degradable according to various international standards and regulations like European standard EN 13432 and American Standard ASTM 6400, which will be eventually biodegraded to carbon dioxide, water and biomass when metabolized in the soil or degradable under standard conditions. Our resins are also certified by Ok Compost, BPI, ABAM, JBPA, FDA, EU Food Contact regulations, etc.

Petroleum is actually a natural substance formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum is separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation. Some fractions are taken off and formed into plastics, tyres etc. and others are used to make PBAT. Here’s the crucial bit – it is what is done to them at this point that determines how they then behave ie. whether or not they will break down quickly or take an age – like plastic. Traditional plastic is engineered to last as long as possible, but PBAT is engineered to be fully biodegradable when composted. This is due to the presence of butylene adipate groups.

In short, just because PBAT is derived from petroleum, doesn’t mean it biodegrades the same way as traditional plastics and synthetics, in fact quite the opposite! It actually biodegrades quicker and better than a corn cob or avocado skin!
