Biodegradable materials, e.g. Notpla, are made from seaweed and plants
Biodegradable materials, such as Notpla, are made from seaweed and plants, offering a promising and sustainable alternative to traditional plastic packaging. Seaweed is a common name for thousands of marine plants and algae found in different water bodies. It is a "primary producer," meaning it gains energy from sunlight and draws necessary materials from nonliving sources.
Seaweed-based bioplastics and coatings can be developed by extracting polymers from raw materials. For instance, carrageenan from seaweeds and pectin from mango peelings can be combined to create a bioplastic. This bioplastic is biodegradable and dissolves into its raw materials when submerged in water.
The development of seaweed-based bioplastics offers a solution to the plastic pollution problem. Seaweed-based food packaging materials are naturally biodegradable and can incorporate functional properties, making them attractive options for the food industry. For example, seaweed-based biopolymers can be used as edible films for food packaging, extending the shelf life of different packed foods.
Additionally, seaweed-based packaging materials can be eco-friendly and cost-effective. Green production methods for creating seaweed films are more viable than conventional extraction methods as they are more environmentally friendly and economical. By using biodegradable materials made from seaweed and plants, we can reduce our reliance on plastic packaging and contribute to a more sustainable future.

Paper-based solutions, e.g. EcoPush, are used for health and beauty products
The beauty industry produces about 120 billion units of packaging annually, with many products packaged in rigid, hard-to-recycle plastic. This has led to a rise in eco-friendly packaging materials, with paper-based solutions at the forefront. Paper-based solutions, such as EcoPush, are being used for health and beauty products to reduce plastic waste.
EcoPush is a paper-based tube applicator that serves as an alternative to traditional plastic packaging. It can be used for a range of health and beauty products, including lip balm, sunscreen, and deodorant. The paperboard used in EcoPush allows for all-over branding, and its optional grease-resistant barrier protects the product.
Another example of a paper-based solution is Pak On Demand™, which produces paper-based mailers, seals, and labels. This is particularly useful for e-commerce retailers looking to cut down on single-use plastics.
Metallized paper is also becoming popular in the beauty industry. It offers a premium, glossy look while maintaining recyclability when used with paper and card primary packaging. This type of paper is very versatile in terms of design and is ideal for use with paperboard products, which are commonly used in the beauty industry.
Some companies, such as LOLI Beauty, are using fully compostable outer packaging made from mushrooms and upcycled hemp. LOLI also uses 100% recycled FSC paperboard for shipping.
While paper-based solutions offer a more sustainable alternative to plastic, it is important to consider the source of the paper. Over three billion trees are cut down each year to produce paper packaging, with many coming from ancient and endangered forests. Therefore, it is crucial to use recycled paper or next-generation materials made from agricultural residues or non-edible food waste to reduce the environmental impact of packaging.

Natural fibres, e.g. coconut fibre, hemp, husk, are cheap and readily available
Natural fibres, such as coconut fibre, hemp, and husk, offer a cost-effective and widely available alternative to plastic packaging. Coconut fibre, derived from the fibrous husk of the coconut, boasts impressive resilience, strength, and durability due to its high lignin and low cellulose content. Its lightweight nature stems from the cavities formed by dried-out sieve cells. This makes it ideal for various packaging applications, particularly in the textile industry, where it is the only fruit fibre used. However, coconut fibre's propensity to absorb oxygen and moisture requires specific storage conditions, including temperature, humidity, and ventilation, to prevent combustion risks and ensure product safety.
Husk, another natural fibre, serves as an innovative and sustainable packaging solution. Recou, a product developed by the German company Prosveration, is crafted from grain husks, typically discarded during grain processing. By utilising an organic binder, Recou can be moulded into various shapes and sizes, mimicking the characteristics of conventional petroleum-based packaging materials like Styrofoam. Biodegradable and customisable, Recou offers a plastic-free option for businesses seeking to protect their products and showcase their sustainability commitments. The pricing of Recou depends on factors such as volume, shape, complexity, and the type of grain husks used, with local sourcing reducing transport costs and emissions.
Hemp presents another natural fibre alternative to plastic packaging, particularly in the cannabis industry. Sustainable cannabis packaging options are available from companies like Sana Packaging, which offers eco-conscious solutions that align with the values of businesses and consumers prioritising environmental responsibility. While specific details about the hemp packaging were scarce, the focus on sustainability and customisation suggests that natural fibres like hemp play a pivotal role in their product offerings.
These natural fibres—coconut fibre, hemp, and husk—exemplify the diverse and accessible alternatives to plastic packaging. Their adoption by companies striving for sustainability underscores the feasibility and benefits of transitioning from plastic to more environmentally friendly materials. With consumers increasingly demanding eco-friendly options, natural fibres present a compelling opportunity for businesses to meet their customers' expectations and contribute to a greener future.

Recycled paper and cardboard are more environmentally friendly than plastic
Plastic packaging has a bad reputation for its contribution to environmental degradation and pollution. While no perfect solution exists, recycled paper and cardboard are considered more environmentally friendly alternatives to plastic packaging.
Paper and cardboard are seen as better for the environment because they are made from trees, which are a renewable resource, unlike plastic, which is made from non-renewable fossil fuels. Paper is also biodegradable and easily recycled, whereas plastic is difficult to recycle to a high level due to waste contamination. Paper is also preferred by consumers, with 62% seeing paper and cardboard packaging as more environmentally friendly, and 70% actively taking steps to reduce their use of plastic packaging.
However, the production of paper and cardboard is water-intensive, and there are risks of deforestation if materials are not sourced sustainably. Paper also generates emissions during manufacturing, and it can be difficult to recycle if contaminated with food or other waste. Paper-based flexible packaging often uses laminations of plastic or aluminium, or coatings of resin, which make it non-recyclable.
Despite these drawbacks, recycled paper and cardboard are still considered preferable to plastic. This is because, in addition to being recyclable, paper and cardboard are biodegradable, so even if they end up in the ocean or waterways, they will have less long-term impact on the environment than plastic. Paper and cardboard are also more likely to be recycled properly, as they do not rely on chemical reactions and are less sensitive to contamination.
Other alternatives to plastic packaging include biodegradable materials such as seaweed and plants, which can be used to create moulded fibre-based trays. Wool is another versatile, compostable, and biodegradable alternative, as well as stone paper, which is made from calcium carbonate.
