Did you know the packaging industry is leading towards a more sustainable future? It’s all thanks to growing environmental concerns like plastic pollution and greenhouse gas emissions. Individuals have become more aware of the long-term impact of single-use plastics on our planet’s ecosystems and wildlife.
Nevertheless, there’s good news! Bioplastics, made from renewable resources like plants and bio-waste, offer a sustainable alternative to traditional plastics. They break down naturally, reducing finite resource reliance and carbon footprint.
Bioplastics are increasingly popular due to their biodegradability and reduced carbon footprint, but concerns about environmental impact, economic feasibility, and production and disposal issues may affect demand.
Rise of Bioplastic Packaging: First Step Towards the Sustainability
The term “bioplastics,” made from biomass resources or biodegradable materials, can be compostable or biodegradable depending on their origin and after-use options. These materials can be designed for either the technical or biological cycle, and some, like PLA and PHA, can be recyclable and compostable if the right infrastructure is in place.
Also, not all compostable materials are bio-based. Some fossil-based compostable plastics, like PBAT and BASF EcoFlex, are industrially compostable. However, they represent a smaller segment of the market as compared to greenhouse gas-based plastics.
According to market research from Future Market Insights, the bioplastics for packaging market is predicted to surpass US$ 30.9 billion by 2033, registering a 10.3% CAGR. Discreet but eco-friendly packaging can benefit from this rise as consumers value simplicity and sustainability.
So, what does anybody know about bioplastics? This broad class of polymers is derived from natural materials, including proteins, fermented sugar cane and maize, and corn starch. Furthermore, there are several kinds. For instance, starch-based polyesters are combined with cellulose-based polyesters, biodegradable polyesters, and many more. The fact that they are constructed of renewable resources rather than fossil fuels makes them awesome.
Current Economic Application of Bioplastic
The concept of bioplastics may seem like a modern invention, but the truth is that they have been around for over a century. In fact, the Ford Model T, one of the world’s first cars, was manufactured using parts made from corn and soybean oil. As the drawbacks of petroleum-based plastics have become more prominent, bioplastics have emerged as a viable alternative to create a variety of products, including food containers, grocery bags, disposable cutlery, and packaging.
One of the most commonly used bioplastics is polylactic acid (PLA), which has been employed for a wide range of applications, such as plastic films, bottles, medical devices, and shrink wrap. Moreover, PLA has been utilized for specialized uses in 3D printing. Leading companies such as Coca-Cola, PepsiCo., Heinz, Ford, Mercedes, and Toyota have already integrated bioplastics into their packaging materials as part of their commitment to sustainability.
Adaption of the Bio-Based Plastic in Early Days
Perhaps surprisingly, the concept of bioplastics is quite new. The earliest known studies with materials from naturally occurring chemicals, such as cellulose, were conducted in the early 1900s. Unfortunately, petroleum-based polymers are more versatile and affordable, so they have yet to be widely used despite their promise. However, there has been a resurgence of interest in bioplastics recently due to rising concerns about plastic pollution and the depletion of fossil resources. Modern renewable bioplastics have resulted from this, and in some situations, end-of-life alternatives like compostability and biodegradability have been enhanced.
A Confluence of Aspects Propels the Augmented Production and Use of Bioplastics
Elevated Demand from Consumers
Consumers have grown awareness of environmental issues in recent years, increasing demand for sustainable products, particularly packaging. Consumers are increasingly seeking alternatives to conventional plastics, which has prompted companies to explore bioplastics to meet these expectations and enhance their brand image. Consequently, there has been a significant drift towards bioplastics in the packaging industry, with more and more companies investing in research and development in bioplastic packaging.
Hitting Sustainability Goals Commercially
It’s heartening to see more and more corporations taking steps towards sustainability by setting ambitious targets for reducing their carbon footprint and transitioning to circular economy models. Bioplastics have appeared as a profitable solution to help companies achieve these goals, and it’s encouraging to see increased investment and interest in bioplastic packaging solutions.
Development of Lowered Carbon Footprint
Bioplastics are better for the environment than regular plastics because they come from plants. When plants grow, they naturally soak up CO2 from the air, and this helps reduce the emissions created when making and breaking down bioplastics. As a result, bioplastics have a lower carbon footprint than traditional plastics.
For example, polylactic acid (PLA), a cornstarch-based bioplastic, emits fewer greenhouse gases than PET. However, the carbon footprint varies based on feedstock cultivation, conversion efficiency, and energy source. Therefore, prudent production process management is essential to maximize the benefits of bioplastics.
Aspects of Biodegradability and Composability
Let’s take a moment to appreciate the positive impact of bioplastics on our environment. With their ability to biodegrade or compost, they offer a sustainable solution for a greener future. However, we must also be mindful that not all bioplastics are created equal and require specific conditions for effective breakdown. We can ensure that bioplastics continue contributing to a healthier planet by gaining more clarity on these terms.
Biodegradable bioplastics can decompose into water, carbon dioxide, and biomass with the help of microorganisms. However, this process often requires industrial composting facilities that maintain high temperatures and humidity. Unfortunately, home composting conditions are usually insufficient for many bioplastics, and proper industrial composting facilities are necessary for these materials to break down more efficiently than conventional plastics in a landfill.
On the other hand, compostable plastics are a subset of biodegradable plastics designed to break down in commercial composting facilities within a specific timeframe, leaving behind no toxic residue. The standards for composability, such as ASTM D6400 in the United States, ensure that these plastics can contribute to valuable compost used to enrich soil. However, the effectiveness of composting bioplastics also depends on the availability and accessibility of these non-universally available composting facilities.
Novel Regulations on Global Level Prompts Demand for Bioplastic Packaging
Around the world, there is a growing commitment to developing and using bioplastics, backed by supportive regulatory initiatives and policies. This is particularly evident in the European Union, where the Circular Economy Package and the Strategy for Plastics in the Circular Economy have been introduced to ensure that plastics are sustainable and made from renewable and recyclable materials. Similarly, countries like Japan are taking proactive steps to promote bioplastics by providing subsidies for their manufacturing and usage.
In current terms, the focus on mitigating plastic waste has taken on a diverse approach in the United States. Different states have implemented various regulations to tackle this issue, with some advocating for bioplastic usage. Notably, the State of California has passed legislation mandating the reduction of plastic waste while promoting the adoption of compostable and recyclable packaging alternatives.
Such regulatory efforts often comprise directives on minimizing single-use plastics, providing incentives for utilizing renewable resources, and establishing standards for compostability and biodegradability. Such measures have significantly impacted the bioplastics market by bolstering demand and creating clear production and disposal guidelines.
