Resumen
Indonesia saat ini menempati urutan ke-2 sebagai negara penghasil sampah plastik. Oleh karena itu, dalam beberapa tahun terakhir, penelitian tentang plastik ramah lingkungan yang dikenal sebagai bioplastik sedang digalakkan. Bioplastik yang terbuat dari bahan alam, sifat mekaniknya tidak sebaik plastik jenis LDPE (Low Density Proly Ethylene). Salah satu bioplastik tersebut adalah berbahan dasar pati-kitosan, yaitu pati yang digunakan dari singkong atau disebut tapioka/pati. Pada penelitian ini, campuran pati-kitosan ditambahkan nanoselulosa dari rumput alang-alang sebagai nanofiller. Pertama, nanoselulosa diasetilasi kemudian dicampur dengan pati-kitosan. Bioplastik yang dibuat pada penelitian ini menggunakan perbandingan tapioka dan kitosan yakni 9 : 0,3. Bioplastik yang dibuat dari campuran pati-kitosan-nanoselulosa , memiliki kekuatan tarik 7,01 MPa, modulus Young atau kekuatan luluh 4,69 MPa dan perpanjangan putus 29,72% untuk ketebalan film 0,28 mm. Dari penelitian ini diketahui bahwa penambahan nanoselulosa dapat meningkatkan sifat mekanik bioplastik pati-kitosan, meskipun belum menyamai sifat mekanik bahan plastik LDPE. Indonesia is currently the 2nd largest producer of plastic waste. Therefore, research on environmentally friendly plastics, known as bioplastics, has been promoted in recent years. Bioplastic is made from natural materials, and its mechanical properties are not as good as LDPE (Low-Density Poly Ethylene) plastic. One of the bioplastics is made from starch-chitosan, the starch used from cassava or called tapioca/starch. In this study, a mixture of starch-chitosan was added with nanocellulose from alang-alang grass as a nanofiller. The first, nanocellulose was acetylated and then mixed with starch-chitosan. Bioplastics were made in this study using a tapioca-chitosan ratio of 9: 0.3. Bioplastic Bioplastic made from a mixture of starch-chitosan-nanocellulose has a tensile strength of 7.01 MPa, Young's modulus or yield strength of 4.69 MPa and elongation of break 29.72% for a film thickness of 0.28 mm. This research shows that the addition of nanocellulose can improve the mechanical properties of starch-chitosan bioplastic. However, it has not matched the mechanical properties of LDPE plastic material.

Resumen
Bioplastics are plastics made from renewable raw materials such as polysaccharides, proteins and lipids. One of the alternative sources of bioplastic raw materials is hydrocolloid from seaweed, which is abundantly available in Indonesia, so that this hydrocolloid-based bioplastic is very prospective to be developed, and can increase the added value of seaweed. The physical and mechanical properties of alginate bioplastics can be improved by combining them with other materials into biocomposite materials that have superior properties and meet specifications. This study aims to determine the effect of calcium chloride (CaCl2) on the physical and mechanical properties of the CMC-Glycerol-Alginate composite bioplastic from Sargassum sp. Bioplastics were made by mixing 0.5 g of alginate flour, added CMC (1.5 g), and 100 ml of distilled water, then stirred with a magnetic stirrer for 10 minutes at 90oC. After that, the temperature was lowered to 40oC and 5 ml of glycerol was added and then homogenized again for 15 minutes. The mixture was filtered and then poured into a glass mold and the surface was leveled using a stainless steel cylinder, then dried in an oven at 80oC for 12 hours. After that the bioplastic is released from the glass plate. In the soaking method, the bioplastic sheets were immersed in a 2% CaCl¬2 solution for 5 minutes, then dried and stored in a desiccator. In the mixing method, 1 gram of CaCl¬2 was put directly into the alginate-CMC-glycerol mixture and homogenized with a magnetic stirrer at 90oC for 15 minutes, then printed on a glass plate, then dried at 100oC for 12 hours. CaCl2 treatment by mixing and soaking decreased elongation, tensile strength, biodegradability and transparency, but increased water resistance and thickness of the alginate-CMC-glycerol composite bioplastic, and changed the surface properties of the bioplastic to be rougher. No new functional groups were formed due to the interaction between alginate, CMC, glycerol, distilled water and CaCl2. Bioplastik adalah plastik yang dibuat dari bahan baku terbarukan seperti polisakarida, protein dan lipida. Salah satu alternatif sumber bahan baku bioplastik adalah hidrokoloid dari rumput laut yang tersedia melimpah di Indonesia, sehingga bioplastik berbahan hidrokoloid ini sangat prospektif untuk dikembangkan, serta dapat meningkatkan nilai tambah rumput laut.Sifat fisik dan mekanik bioplastik alginat dapat ditingkatkan dengan cara dikombinasi dengan bahan lain menjadi material biokomposit yang memiliki sifat unggul dan memenuhi spesifikasi.Penelitian ini bertujuan untuk mengetahui pengaruh kalsium klorida (CaCl2) terhadap sifat fisik dan mekanik bioplastik komposit CMC- Gliserol-Alginat dari Sargassum sp.Bioplastik dibuat mdengan mencampurkan tepung alginat sebanyak 0,5 g ditambahkan CMC ( 1,5 g), dan akuades 100 ml, lalu diaduk dengan magnetic stirrer selama 10 menit pada suhu 90oC. Setelah itu, suhu diturunkan sampai 40oC dan ditambahkan gliserol 5 ml lalu dihomogenkan lagi selama 15 menit. Campuran disaring lalu dituang dalam cetakan kaca dan diratakan permukaannya menggunakan silinder stainless steel, kemudian dikeringkan dalam oven pada suhu 80oC selama 12 jam. Setelah itu bioplastik dilepaskan dari pelat kaca. Pada metoda soaking lembaran bioplastik direndam dalam larutan CaCl­2 2% selama 5 menit, lalu dikeringkan dan disimpan dalam desikator. Pada metoda mixing, CaCl­2 sebanyak 1 gram dimasukkan langsung ke dalam campuran alginat-CMC-gliserol dan dihomogenkan dengan magnetic stirrer pada suhu 90oC selama 15 menit, lalu dicetak dalam pelat kaca, lalu dikeringkan pada suhu 100oC selama 12 jam. Perlakuan CaCl2 dengan cara mixing dan soaking menurunkan elongasi, kuat tarik, biodegradabilitas dan transparansi, tetapi meningkatkan ketahanan air dan ketebalan bioplastik komposit alginat-CMC-gliserol, serta mengubah sifat permukaan bioplastik menjadi lebih kasar. Tidak terdapat gugus fungsi baru yang terbentuk akibat interaksi antara alginat, CMC, gliserol, akuades dan CaCl2.

Resumen
Plastik sintetis yang digunakan sebagai pembungkus makanan dapat menimbulkan masalah lingkungan, karena sulit terurai sehingga menjadi sampah. Bioplastik dapat menjadi alternatif plastik komersial karena terbuat dari bahan alami sehingga mudah terurai. Berbagai bahan dasar pembuatan bioplastik telah ditemukan, salah satunya berbahan dasar karagenan. Bioplastik memiliki kekurangan seperti teksturnya yang kaku dan rapuh, sehingga perlu ditambahkan gliserol sebagai pemlastis. Bioplastik dapat terdegradasi lebih cepat sehingga perlu ditambahkan pengawet alami. Karboksimetil kitosan adalah polimer alami yang digunakan sebagai pengawet karena memiliki aktivitas antibakteri. Penelitian ini bertujuan mengetahui penambahan karboksimetil kitosan terhadap waktu degradasi bioplastik. Metode yang digunakan dalam penelitian bersifat eksperimental labolatoris. Pembuatan bioplastik menggunakan karboksimetil kitosan dengan konsentrasi 2 g, 3 g, 4 g dan 5 g, karagenan 3 g dan gliserol 1,7 ml. Berdasarkan hasil penelitian diperoleh nilai ketebalan sebesar 0,25 mm – 0,82 mm, nilai kuat tarik sebesar 1,04 MPa – 1,61 MPa, uji biodegradabilitas tercepat selama 116 menit dan terlama selama 373 menit. Pemberian karboksimetil kitosan dapat mempengaruhi waktu degradasi bioplastik dan pada konsentrasi karboksimetil kitosan 5 gram dapat terdegradasi lebih lama.The use of food wrapping plastic (synthetic) becomes waste that pollutes the environment, because its difficult to decompose. Bioplastics can be an alternative to commercial plastics because is making from natural materials so they are easily biodegradable. Various basic materials for making bioplastics have been found, one of which is carrageenan. Bioplastics have drawbacks such as their rigid and brittle texture, so additional ingredients such as glycerol are needed to be added as plasticizers. Bioplastics can be degraded more quickly, so natural preservatives need to be added. Carboxymethyl chitosan is a natural polimer that is used as a preservative because it has antibacterial activity. This study aims to determine the bioplastic characteristics of carrageenan with the addition of glycerol and carboxymethyl chitosan and to determine the appropriate concentration of carboxymethyl chitosan so that bioplastics from carrageenan and glycerol can last a long time. The method used was experimental laboratory, making bioplastics using carboxymethyl chitosan with concentrations of 2 g, 3 g, 4 g and 5 g, carrageenan 3 g and glycerol 1.7 ml. Results of the research that has been carried out, the results of the bioplastic characteristics in the form of a thickness value of 0.25 mm - 0.82 mm, a tensile strength value of 1.04 MPa - 1.61 MPa, the fastest biodegradability test for 116 minutes and the longest for 373 minutes. Carboxymethyl chitosan affects the bioplastic degradation time of carrageenan.

Plastic production is a necessity for humanity today. It is impossible to imagine an industry without it, whether it is the production of children's toys or the production of test tubes. However, the issue of environmental pollution is growing in direct proportion to the increase in plastic production. For example, mankind has created about 380 tons of plastic in 2018, of which only a small part was disposed of. Therefore, the issue of alternatives to plastics that are tolerant of the environment and human health is only gaining momentum. The main task of this work is to create a viable bioplastic from starch that can compete in the market with the usual sample. In fact, starch has long been used in this industry, this polysaccharide is a successful raw material for plastic production due to its properties, which are provided by its components: amylase and amylopectin, amylase in turn responsible for stickiness and water absorption, and amylopectin for strength. Виробництво пластику - це необхідність для людства сьогодні. Неможливо уявити собі індустрію без нього, незалежно від того, чи є це виробництво дитячих іграшок чи виробництво пробірок. Однак питання забруднення навколишнього середовища зростає прямо пропорційно збільшенню виробництва пластмас. Наприклад, людство виробило близько 380 тонн пластмаси у 2018 році, з якої була використана лише невелика частина. Тому питання альтернатив пластмас, які є толерантними до навколишнього середовища та здоров'я людини, отримує лише імпульс. Основним завданням цієї роботи є створення стійкого біопластику з крохмалю, який може конкурувати на ринку зі звичайним зразком. Фактично, крохмаль давно використовується в цій галузі, цей полісахарид є успішною сировиною для виробництва пластмас завдяки своїм властивостям, які забезпечуються його компонентами: амілаза та амілопектин, амілаза, яка відповідає за липкість та поглинання води, а також амілопектин для міцності.

Resumen
Ett av världens största miljöproblem är plastnedskräpning. På många platser kan spår av mänsklig närvaro ses i form av skräp av plast. År 2011 tillverkades det 280 miljoner ton plast, det motsvarar ungefär 28 000 Eiffeltorn. I Sverige förbrukades år 2010 ungefär 880 000 ton plast. I Asien produceras ungefär 50 % av all världens plast och Kina står för cirka hälften av detta. Nordamerika och Europa står för cirka 40 % av världens plastproduktion. Resterande produktion av plast är fördelat på Afrika och Sydamerika. Kommersiell plast är uppbyggd av små enheter kallade polymerer. Polymerer är i sin tur uppbyggda av ännu mindre enheter som kallas monomerer. Dessa monomerer är i dagsläget framställda av petroleum (råolja/mineralolja). Ungefär 4 % av världens oljekonsumtion går åt som råvara till att producera plast och lika mycket olja används som bränsle i tillverkningsprocessen. Begreppet bioplast är en hel familj av material som är biologiskt nedbrytbar, biobaserade eller bådadera. Det är dock inte en självklarhet att bioplaster besitter båda egenskaperna. PHA-plast är biobaserad och biologisk nedbrytbar, vilket är anledningen till att den står i fokus under detta examensarbete. För produktion av PHA-plast används en trestegsprocess, vilket innefattar ett fermenteringssteg, ett selektionssteg och ett ackumuleringssteg. Sist sker en extraktion för att frigöra PHA- plasten från det övriga organiska materialet. Syftet med det här examensarbetet är att med hjälp av framställning av bioplast främja miljön, vilket en anläggning som producerar bioplast skulle göra eftersom en del av den fossiloljebaserade plasten skulle kunna bytas ut mot bioplasten PHA. Större framställningsmöjligheter av bioplast i Värmland skulle medföra ett ökat intresse av en produktionsanläggning. Målet är att inventera olika industrier runt om i Värmland, i första hand matindustrier och skogsindustrier, och utreda deras processavloppsvattens potential att producera VFA. I detta examensarbete har fermenteringsförsök genomförts satsvis på processavloppsvatten från OLW, Barilla (Wasa), Skoghall, Gruvön och Rottneros. Försöken visar deras potential att producera VFA. Experimenten utfördes med ett konstant pH på 6 och varierande uppehållstid. Resultaten visade att OLW och Barilla har bäst potential till VFA-produktion med 4500 mg/l respektive 1610 mg/l. Spädning av OLWs och Barillas processavloppsvatten visade sig vara en gynnsam åtgärd, då VFA-produktionen ökade snabbare i jämförelse med de tester som utfördes vid icke-spädning. Dock erhölls inte lika stor totalmängd av VFA. Det är dock bättre att producera en större mängd VFA och på så vis låta processen ta längre tid. Vid fortsatta experiment rekommenderas att göra ytterligare försök på OLW och Barillas processavloppsvatten då de visade bäst potential till VFA-produktion.
One of the biggest environmental problems is the plastic littering. In many places traces of human presence is seen in the form of plastic littering. In the year 2011, 280 million tons of plastic was produced, which represents about 28 000 Eiffel Towers. In Sweden, about 880 000 tons of plastic a year is consumed, according to figures from 2010. Approximately 50 % of all the world's plastics are produced In Asia and China accounts for about half of it. North America and Europe account for about 40% of the world's plastic production. The remaining production is distributed between Africa and South America. Commercial plastic is made from small units called polymers. A polymer consists of smaller units called monomers. In present, these monomers are produced out of petroleum (crude oil/ mineral oil). Approximately 4% of the world’s oil consumption is spent as raw material to produce plastic and the same amount of oil is used as fuel in the plastic production process. The term bio-plastic is used for a family of materials which are biodegradable, bio- based or both. However, it is not given that bioplastics do possess both properties. PHA plastics are both bio based and biodegradable, which is why it is the focus for this thesis. Production of PHA plastic is a three-step process comprising a fermentation step, a selection step, and an accumulation stage. Finally, there is an extraction to release the PHA plastic from the organic material. The aim of this thesis is to aid the production of bioplastics in order to lessen the environmental load of plastics. The more bioplastic that can be produced, the greater the interest of a bioplastic-producing plant in Värmland. The goal is to make an inventory of industries around Värmland, primarily food industries and forest industries, and to quantify the potential of their process wastewaters to produce VFA. In this thesis, fermentation experiments conducted batch-wise was performed with process wastewater from OLW, Barilla (Wasa), Skoghall, Gruvön and Rottneros. The experiments showed the wastewaters potential to produce VFA. The experiments were performed with a constant pH of 6 and with varying residence time. The results showed that OLW and Barilla has the highest potential for VFA production with 4500 mg/l and 1610 mg/l, respectively. Dilution of OLWs and Barillas process water turned out to be favorable, as the VFA production increased rapidly in comparison with those tests that were conducted under non-dilution. The total production of VFA, however, was not as high. In further experiments, it is recommended to make another attempt at the OLWs and Barillas process wastewater since they showed the best potential for VFA production.

Resumen
Modern chemistry has reached the level of molecular research, which made it possible to reveal the mechanisms of many processes in a living organism, synthesize substances that do not exist in nature, and decipher the genetic mechanisms of heredity. The development of the production of both biologically derived and biodegradable polymers cannot be stopped. Nowadays biopolymers in many areas represent a serious alternative to traditional polymeric materials. The notion that they are not competitive will not hold out for a long time. What is more, they certainly will not become a panacea for all environmental problems. The concept of biopolymers as 100% resource conserving agents is also premature. However, they open up new prospects in the post-oil era.

Resumen
Microalgae used in sewers to capture CO2 eventually turns into waste material. Through the use oftheir biomass, the waste algae can be given a new purpose. In this study attempts to extract starch or PHA from three different algae; Calothrix Scytonemicola, Scenedesmus Almeriensis and Neochloris Oleoabundans, were made. We also attempted to create a bio-based plastic material. Both Scenedesmus Almeriensis and Neochloris Oleoabundans are starch rich microalga. By washing with acetone, cryo grinding, use of ultrasonic homogenizer and dialysis, starch was likely extracted successfully. The extracted material and the plasticiser Carboxymethyl Cellulose (CMC) was used to cast plastic film. The cast film was very thin and brittle; perhaps by using different plasticisers or additives a more usable bio-based plastic material can be created. The PHA rich algae Calothrix Scytonemicola was used to extract PHA. The algae was washed with acetone, cryo grinded and then mixed with Sodium Hypochlorite(aq) and deionised water to extract the desired PHA. Due to a shortage of algae very small amounts of material could be extracted. Therefore, the casting of a plastic film was performed with commercial PH3B, which is a type of PHA. Three attempts were conducted. The first one with only chloroform, the second one with CMC and chloroform and the last one with Sucrose Octaacetate and chloroform. The film with Sucrose Octaacetate gave the best plastic material in regards to mechanical properties.
Mikroalger som används i kloaker för att binda CO2 blir till slut restavfall. Genom att använda dess biomassa kan restalgerna få ett nytt syfte. I denna studie utfördes extraktionsförsök av stärkelse samt PHA från tre olika alger, Calothrix Scytonemicola, Scenedesmus Almeriensis och Neochloris Oleoabundans. Ytterligare försök genomfördes för att försöka framställa ett biobaserat plastmaterial. Både Scenedesmus Almeriensis och Neochloris Oleoabundans är stärkelserika mikroalger. Genom att tvätta dem med aceton, kryomalning, användning av en ultrasonic homogenizer och dialys kunde stärkelse troligtvis extraheras. Det extraherade materialet blandades med karboxymetylcellulosa (CMC) för att skapa en plastfilm. Filmen blev väldigt tunn och spröd, således behövs antingen en annat mjukningsmedel eller tillägg av additiv för att skapa ett mer användningsbart biobaserat plastmaterial. Den PHA-rika algen Calothrix Scytonemicola användes vid extraktionen av PHA. Algerna tvättades med aceton och kryomaldes innan PHA förhoppningsvis extraheras med hjälp av natriumhypoklorit(aq) och avjonat vatten. På grund av en för liten mängd tillgänglig alg extraherades endast en liten mängd material. Det var därför inte möjligt att skapa en plastfilm av vårt extrakt utan istället användes kommersiell PH3B, som är en typ av PHA. Tre försök genomfördes, en med endast kloroform, en med CMC och kloroform och den sista med sucrose octaacetate och kloroform. Den sistnämnda filmen gav det bästa plastmaterialet med avseende på de mekaniska egenskaperna.

Texto completo
Resumen
Cyanobateria are promising cell factories due to their minimal nutrient requirements and utilization of asmospheric carbon di-oxide as its sole carbon source. In particular, polyhydroxybutyrate (PHB) is an industrially useful bio plastic that is produced naturally by some cyanobacteria. Furthermore, PHB biosynthetic pathway is a starting point for production of the biofuel, 1-butanol. There has been much genetic engineering effort toward increasing the production of PHB from cyanobacteria. These have been focused on increasing the pool of acetyl-CoA precursor, or increasing the amount of the reductant NADPH. The upstream process for increasing these reactants is complex and involves many genes. In this contect, cyanobacteria libraries will contribute to reveal genes or gene fragments that are responsible for production of PHB, alkanes and other high value compounds. In pursuit of finding these novel genes or genefragments, a transcription factor library is created in this study with 50 transcription factors. Furthermore, the process is optimized towards the creation of genomic fragment library and metagenomic fragment library with 26 diverse strains. Membersof the transcription factor library are over-expressed by a PHB - producing host Synechocystis PCC 6803 and the process towards creation of genomic and metagenomic libraries is optimized. The members of the metagenomic library can be screened for increased PHB, alkanes, lactate and other high value products and the potential members can be isolated and characterized.

Resumen
The Sri Lankan construction industry is facing significant challenges in building construction projects due to the negative impacts of using traditional building materials. Consequently, there has been a surge of interest in sustainable materials, and among them, bioplastics have emerged as a promising alternative. The aim of this study is to investigate the potential of bioplastics as a sustainable building material specifically for the Sri Lankan construction industry. To achieve this, the study applied a qualitative research approach to collect data through semi-structured interviews. The research objectives are to identify alternative sustainable materials used in construction and identify how bioplastics could contribute to the construction industry as ta sustainable material. In addition to that, the study also identifies the motivators and challenges to the use of polymer building materials in Sri Lanka and subsequently develop a framework including potential strategies to use bioplastic as a sustainable construction material. The study's findings have identified significant factors that establish bioplastics as a sustainable material suitable for the Sri Lankan construction sector. Moreover, the research offers valuable recommendations to address challenges related to the adoption of polymer building materials. Furthermore, the study would contribute to the formulation of policies and regulations that promote the use of bioplastics as a sustainable building material.

Resumen
The manufacture of bioplastic from potato starch (Solanum tuberosum L.) and glycerol from waste cooking oil with the addition of TiO2 has been done by varying the concentration of TiO2. This study aims to study the effect of the addition of TiO2 on the physical and mechanical properties of potato starch and glycerol from leech oil. The research was conducted by making glycerol from waste cooking oil, making bioplastic film with various concentrations of TiO2 (0; 1; 2; 3 and 4%), characterization of bioplastic, which includes physical and mechanical properties. The addition of TiO2 as a bioplastic filler can affect its physical and mechanical properties. The result showed that each addition of 1% TiO2 increased the thickness by 22,966 microns, the tensile strength value by 0.0853 N/mm2, the average Young’s modulus by 0.0599 MPa, and decreased elongation by 5.0987%. The best bioplastic mechanical test results were produced at a starch composition of 2.5 grams and 2% (w/w) of TiO2 particles.

Resumen
Incorporation of chitosan into the bioplastic film could improve its mechanical properties. However, aqueous acidic solution is required to dissolve the chitosan. The aim of the present work was to explore the potential use of acidic NADES as the plasticizer as well as a solvent for chitosan without the addition of aqueous acidic solution. The film-forming solution consisted of sago starch as the matrix and chitosan as the filler was prepared by solution casting and evaporation method in the presence of acidic NADES. Acidic NADES was obtained by mixing choline chloride (ChCl) and lactic acid (LA) as the hydrogen bond acceptor and hydrogen bond donor, respectively. The mechanical properties and water uptake ability of chitosan-reinforced starch-based bioplastic films plasticized with acidic NADES were compared with the bioplastic films plasticized with conventional plasticizer, glycerol in the absence and presence of acetic acid solution. The results revealed that acidic NADES was capable of plasticizing the starch and dissolve the chitosan. Bioplastic film plasticized with acidic NADES achieved higher tensile strength and lower water uptake than the bioplastic film plasticized with glycerol in the presence of acetic acid solution. The interaction between chitosan and acidic NADES was confirmed by Fourier-transform infrared spectroscopy (FTIR). FTIR results exhibited that the amide II band of chitosan in the ChCl/LA film had shifted, and its intensity had decreased to almost undetectable.

Resumen
This brief outlines how the environmental benefits of bioplastics are tempered by waste disposal challenges and why Thailand and countries in Southeast Asia should consider policies and incentives to capitalize on rocketing bioplastics demand. Noting Thailand is the world’s second-largest bioplastics producer, the brief explains the costs, production processes, and uses of the materials. It looks closely at their greenhouse gas emissions and complex issues around end-of-life biodegradation. It shows why countries should invest in infrastructure such as industrial composting facilities and provide fresh financial incentives for manufacturers to help meet growing demand and drive the shift to a bio-based economy.

Resumen
This rapid evidence assessment undertaken by RSM UK Consulting LLP (RSM) and Dr Samuel Short (University of Cambridge) aimed to develop an understanding of the alternatives to single-use plastics in food packaging and production in terms of their risks and opportunities, as well as potential future developments. Literature from within and beyond the UK was gathered from academic databases and reports published by government and non-governmental organisations such as environmental charities. Evidence from the literature was supplemented by findings from a workshop with experts in the field from a variety of industries such as academia, manufacturing, and government. Two broad groups of alternatives were established: material/product alternatives (traditional materials, natural fibres, biopolymers synthesised from biomass, biopolymers synthesised from bioderived monomers, biopolymers produced by microorganisms) and, and system/process alternatives (reducing, reusing, and recycling food packaging and, active and intelligent packaging). These alternatives and systems vary considerably in terms of their properties, such as effectiveness as a barrier to moisture or contamination, convenience for consumers, production costs, and potential for commercialisation. Our review also highlighted gaps in the current knowledge, for example in terms of consumer acceptance and carbon footprint at each stage of their life cycle. The capacity to produce bioplastics (i.e. biopolymers that look and feel similar to conventional plastics but are made from natural materials rather than fossil fuels and are biodegradable or compostable) is anticipated to increase globally from 2.1 million tonnes in 2019 to 6.3 million tonnes by 2027. This growth appears to be enabled by increased consumer awareness of environmental issues and existing regulation and legislation encouraging the development and establishment of a circular economy. However, there are barriers that may challenge this growth. These include already established industry regimes, high production cost of novel materials and a lack of waste management guidance. Overall, fossil-based conventional plastics are a very cheap, versatile material compared to the alternatives currently being developed and tested. Because of this, they might remain the preferred industry choice for certain applications, while alternatives continue to be optimised and commercially scaled. To add to this, the reviewed evidence suggests that there is unlikely to be one single solution to the single-use plastics problem. The solution will likely draw on a range of materials and systems depending on food type and context.
