Unfortunately when organic food packaging is added to the recycling process, it contaminates the purity of the raw materials which results in large batches being sent to the landfills. Large amounts of different materials, like paper, glass and plastics, are used globally to manufacture packaging materials and more than two thirds are used in the food sector alone. As single-use packaging materials theyre very expensive and impractical. We shouldnt forget though, that plastic-free packaging is not always guilt-free packaging. Composting is the controlled aerobic or biological degradation of organic materials to generate a carbon and nutrient rich compost that acts as a natural fertiliser than can be used to grow crops and thus reducing the demand for chemical fertilisers [13,83]. This requires food packaging with a good barrier against microbes, water vapour, oxygen, light, mechanical contaminants and other external factors that affect the properties of the product [101]. L.K.N. Lets rule out a paper bag as we already know that would be very messy.

As a result of enhanced water barrier properties, the nanocomposites were able to retard lipid oxidation of the packaged processed meat, effectively extending the shelf life. It is paramount to note that non-biodegradable bioplastics from bio sources still have advantages over biodegradable fossil fuel plastics. Raheem D. Application of plastics and paper as food packaging materialsAn overview. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (. Moisture barrier properties of biobased packaging materials are generally inferior to those of conventional materials [110,115]. Biodegradation is a process of defragmentation, initiated by heat, moisture, and/or microbial enzymes, which transforms longer molecular substances into smaller compounds [22]. Blends with other non-toxic naturally occurring materials provide safe packaging composites. Food packagingRoles, materials, and environmental issues. Biodegradable materials are generally characterised by limited durability whilst their petroleum-based counterparts are more durable. I'd like you to contact me regarding my enquiry only. Betancourt N.G., Cree D.E. And they still contribute to greenhouse gas emissions. These products will contribute to the development of a circular bio economy. Jacob J., Lawal U., Thomas S., Valapa R.B. Africa is yet to make its mark as it is still lagging behind in terms of production of bioplastics, despite the availability of raw material resources. The developed films were used to package sliced salami, a fatty food. Jabeen N., Majid I., Nayik G.A. It would be a shame to offset the only positive spinoff of COVID-19, by recklessly forgoing eco-friendly practices during the pandemic. Much of our waste is taken to landfill sites. The main issue with bio-plastics (such as PLA or Bio-PE) is that they require specialised conditions in order to biodegrade efficiently. PLA is environmentally friendly biodegradable thermoplastic polyester. The developed material was evaluated for bread fungal protection compared to petroleum based biaxially oriented polypropylene (BOPP), a common bread packaging material. The packaging industry is the largest and growing consumer of synthetic plastics derived from fossil fuels. The following Table 1 shows some research on composites from PLA with natural fillers to improve its properties as well as reduce the cost of the final composite. Chapter 4-Biobased Polymer Composite from Poly (Lactic Acid): Processing, Fabrication, and Characterization for Food Packaging. Required mechanical properties ensure the packaged products are protected from external forces and/or ensure the packaging material has adequate strength to contain the packaged goods [109]. In the packaging industry, food packaging accounts for 50% of the plastics derived from fossil fuels [11]. Cazn P., Velazquez G., Ramrez J.A., Vzquez M. Polysaccharide-based films and coatings for food packaging: A review. All these challenges can be overcome by employing various methods, including blending with other polymers, making composites, as well as coating and polymer modification [24,36,74,75]. However, new techniques for the economical production of PLA are contributing to the growth of utilisation in packaging and textile sectors [2,45,81]. Biopolymers have emerged as promising green materials although they still have very low market uptake. Growing environmental concerns have placed packaging under scrutiny as it is a constant source of high amounts of plastic waste and this has brought about the need to do extensive research into renewable alternatives [15,16,17]. Too many subscribe attempts for this email address. However, they have proven to have a grave impact on the environment and its habitants. Southern Africa has some of the richest vegetation on earth and has since been recognised as one of the most fascinating and vital areas of the world from an ecological and evolutionary point of view [133,134]. The packaging also displayed better properties that were enhanced by ultraviolet (UV) sterilisation treatment. Petrochemical plastics have been used widely since their inception to date. Biodegradable polymers have replaced only about 1% of global plastics [10,67]. Bethany is a freelance writer specialising in travel, adventure sports, sustainability and eco-friendly living. But irresponsibly disposed of cigarette butts. Asia was the major producer accounting for 45% of global production. In: Motarjemi Y., editor. From factory to fashion-show, the clothing industry uses vast quantities of water throughout the intensive production and manufacturing process of creating garments.. Ramos .L., Pereira R.N., Cerqueira M.A., Martins J.R., Teixeira J.A., Malcata F.X., Vicente A.A. Chapter 8Bio-Based Nanocomposites for Food Packaging and Their Effect in Food Quality and Safety. Active packaging films have been developed by [121] using PLA and bleached bagasse carboxymethyl cellulose for mango storage life extension. Attaran S.A., Hassan A., Wahit M.U. Zhao Y., Qiu J., Feng H., Zhang M., Lei L., Wu X. It may seem like too much effort to disinfect and recycle every item, but unprecedented times call for unprecedented measures (and not the vandalism of mobile infrastructure). However, when visualising the future it is highly plausible that there will be a massive move towards urban farming and sophisticated bartering systems. Id like you to contact me regarding my enquiry and would also like to receive marketing updates from Eco To Go Food Packs. Food contact substances and chemicals of concern: A comparison of inventories. Up to 40% less fuel is required to transport plastic bottles than glass bottles. Their use has grown to address advanced functionality packaging applications like active packaging and modified atmosphere packaging applications. This could be on a home compost heap or an industrial composting facility. Bioplastics and food packaging: A review. Examples include: Plant resources provide subsistence and income for millions of people, mostly in developing countries. The inconvenient truth, however, is that there is an undeniable link between an unbalanced eco-system and COVID-19. Hottle T., Bilec M., Landis A. Sustainability assessments of bio-based polymers. In the figure, fossil-based polymers are shown in bold. It can also be simply defined as a process by which substances are broken down by living organisms [2,23,24]. It presents packaging applications for a wider array of products including films, forms, food containers and coatings among many others [2,36,50,75]. Grab our PDF guide with 104 ways to reduce your plastic at home. Adeyeye O., Sadiku E.R., Reddy A.B., Ndamase A.S., Makgatho G., Sellamuthu P.S., Perumal A.B., Nambiar R.B., Fasiku V.O., Ibrahim I.D. A biodegradable material is one that can be broken down by microbes and used as a food source. In addition to the GPGP causing an imbalance to the subatomic levels of the eco-system, when plastic packaging ends up in our ocean it frequently injures and kills marine life. In: Grumezescu A.M., editor. The hierarchy ranks the treatments of waste based on the ability to conserve resources, with the prevention or minimisation of waste being the most preferred route to follow into the future, and the disposal of waste being the worst-case scenario to be avoided at all costs. However, sustainable packaging is still a multifaceted concept that necessitates investigations and documentation to appraise the package design, materials used, processing, and life cycles. This means that food contaminated packaging can be sent for composting with no need for cleaning. As a result of their low cost, biodegradability, large availability, and valuable mechanical and physical attributes, a wide variety of lignocellulosic fibres and natural fillers from agricultural and industrial crops, such as corn, wheat, and bagasse, have been employed in the production of composites for areas including packaging, automotive and building industry [30,96,97,98]. Bioplastics material coordinate system. Silva T.F.D., Menezes F., Montagna L.S., Lemes A.P., Passador F.R. On the other hand, thermosets cannot be reprocessed by heat once they are formed. A glass jar or a tin can be reused hundreds of times before eventually being recycled. In terms of the ocean, this volume could be achieved by dumping a plastic-filled garbage truck into the ocean every minute. If not, yesterdays sandwich wrapper may well end up polluting oceans and rivers. The rise in global population will demand more food and hence more packaging. Dikky I., Stevia S. Replacing plastic: An assessment of new material for food production package to re-engineer packaging industry based on multi-criteria analyses; Proceedings of the First ASEAN Business, Environment and Technology Symposium (ABEATS 2019); Bogor, Indonesia. If not, it will sit next to plastic in landfill, taking up a greater volume of space. Plastics have remained the material of choice, and after serving their intended purpose, a large proportion ends up in the environment where they persist for centuries. If you are under 16 years of age you MUST obtain parental consent before subscribing to our email newsletter. The key to successfully returning this material to the earth is to tear it up into strips and combine it with the correct ratio of green waste. Kosior E., Mitchell J. Data from [64]. Plant-based fibrous materials used with biopolymers/biomass-derived polymers can yield environmentally friendly and biodegradable green composites with sufficient flexibility and mechanical strength comparable to commercially available petroleum-based polymers [71,99,100,101]. This property is affected by permeability, diffusivity, solubility across the barrier, and affinity towards moisture of the packaging material [22]. Chamas A., Moon H., Zheng J., Qiu Y., Tabassum T., Jang J.H., Abu-Omar M., Scott S.L., Suh S. Degradation Rates of Plastics in the Environment. The energy and C02 emissions involved in transporting your pasta sauce staple are going to be high. Permeability to carbon dioxide compared to that of oxygen (perm selectivity) is higher than that of most conventional fossil fuel-based plastics. Lightweight Materials from Biopolymers and Biofibers. It is reported that more studies are still required to assess how the process of biodegradation affects properties of PLA-based composites for food packaging [116]. The routes of note are biodegradation in soil, compost, and aquatic environments since most of the packaging developed would be single use and easily find its way into the environment or into compost facilities. As a result of its inherent drawbacks, PLA can be used with numerous organic fibres and fillers to improve some of its properties such as mechanical strength and reduced gas or moisture permeability. The adoption of biodegradable polymers for packaging can provide a solution to waste-disposal problems associated with the traditional petroleum-derived packing materials as well as address the fact that crude oil and natural gas resources are limited [7,25,68,69,70,71]. However, it can be repurposed into compostable (or biodegradable) food packaging before this stage, making this material one of the most convenient eco-friendly options.
