Bioplastics are here to revolutionise the way we think about materials. In a world where sustainability and environmental friendliness are becoming increasingly important, these new materials present themselves as an innovative alternative to conventional plastics. But what exactly are they and what benefits do they offer?
As integral product developers, at Atienza & Climent we are aware of all the novelties related to manufacturing materials. In this article we analyse the characteristics and benefits of this discovery.
Sustainable alternatives to traditional plastics are needed
Traditional plastic, derived from petroleum, has been an almost indispensable component of modern life, but its negative impact on the environment is unquestionable. This is where bioplastics from organic waste come into play, a sustainable solution that harnesses biological materials to reduce dependence on fossil resources. Such materials not only reduce pollutant emissions, but also promote a more efficient use of natural resources, closing the life cycle of many products that were previously considered waste.
What are bioplastics?
Si se pretende entender la relevancia de estos nuevos materiales, primero es importante saber qué son los bioplásticos. A grandes rasgos, son polímeros obtenidos de fuentes renovables, como plantas o residuos orgánicos, en lugar de utilizar petróleo como materia prima. Existen diferentes tipos, algunos son biodegradables, lo que significa que se descomponen de manera natural bajo ciertas condiciones, mientras que otros no lo son, pero siguen siendo más sostenibles en su producción.
Is bioplastic plastic?
Although naturally occurring, bioplastics are essentially plastics. This means that they can fulfil the same functions as traditional plastics: strength, versatility and lightness. However, because they come from renewable sources, they have much less impact on the environment.
Types of bioplastics
There are different types of bioplastics, each with specific characteristics that make them suitable for different applications. They are generally classified into two groups: on the one hand, there are those that are biodegradable, which can decompose under industrial composting conditions or even in natural environments. On the other hand, there are the non-biodegradable ones, which, although they do not decompose as easily, are obtained with more sustainable production processes than conventional plastics.
Advantages of bioplastics over conventional plastics
These innovative materials offer multiple benefits compared to conventional plastics.
Advantages of bioplastics:
- Reduced dependence on oil: because they are obtained from organic materials, the need for fossil fuels is reduced.
- Lower carbon footprint: during their production they emit less greenhouse gases than conventional materials.
- Biodegradability: some of them decompose more quickly under controlled conditions.
- Use of waste: many of them are made from agricultural or industrial waste.
- Recyclable: they can be recycled in many cases, contributing to the circular economy and waste reduction.
All these advantages make them a perfect option for those seeking more sustainable solutions without sacrificing the practicality and versatility of conventional polymers.
What are bioplastics for?
Bioplastics have found a place in various industries thanks to their properties. They are used in the manufacture of packaging, bags, disposable utensils, medical products and even in the automotive industry. Thanks to their durability and sustainability, these materials are gradually replacing conventional plastics in many everyday applications.
Limitations and challenges of bioplastics
Despite being a more sustainable option and their many benefits, they also face a number of challenges.
Some of the problems of bioplastics are:
- Production costs: they may require more expensive production processes than conventional plastics.
- Limited biodegradability: not all bioplastics degrade easily under natural conditions.
- Complications in the recycling chain: sometimes they cannot be recycled together with other waste.
- Dependence on agriculture: their production can compete with food production.
These obstacles make it clear that while these materials are a promising alternative, much work remains to be done to perfect their use and production.
Materials and manufacturing of bioplastics
Bioplastics can be made from a variety of materials, such as corn starch, sugar cane or vegetable oils. The manufacturing process usually requires less energy and generates fewer emissions compared to petroleum-based plastic. This ability to be produced from renewable resources is one of their main advantages over traditional polymers.
Bioplastics applications in the toy industry
The toy industry has traditionally been characterised by its constant renewal and search for new alternatives, and the use of new materials in its production processes is a clear example of this.
Here is a list of some applications of bioplastics in toys:
- Biodegradable toys: made from materials that decompose in compost.
- Sustainable packaging: used to create recyclable packaging.
- Safe accessories: non-toxic materials that are safe for children.
The use of these materials in the toy sector not only promotes sustainability, but also ensures safer and more environmentally friendly products.
The future of bioplastics as a sustainable alternative
As the demand for eco-friendly solutions continues to grow, the future of bioplastics to improve the circular economy looks promising. These materials not only help reduce pollution, but also encourage a more responsible production and consumption model.
Ongoing research aims to improve their efficiency and reduce production costs, making them accessible in a wider range of sectors.
Steps towards wider adoption of bioplastics
It is clear that bioplastics are positioning themselves as a more achievable alternative, but for them to be widely adopted by the bulk of today’s industries, a number of important steps need to be taken:
- Investments in infrastructure: in order to facilitate recycling and composting.
- Government incentives: policies that support and encourage their production and use.
- Public awareness: increasing consumer knowledge of its benefits and uses.
- Process improvement: optimisation of production to reduce associated costs.
The adoption of these materials will depend largely on the ability of industries and governments to drive the necessary changes, allowing them to become a fundamental part of the global economy.
