Bioplastics are made of bio-based polymers and are produced utilizing sustainable and renewable resources, such as corn or sugar cane.
Bioplastics operate nearly identically to plastics made from petroleum, and they are quickly overtaking them in popularity as a packaging material. A notable prediction from scientists is that bioplastics could reduce carbon dioxide emissions by as much as 70%. They are also 65% more energy efficient when being manufactured, making them the more environmentally responsible option.
Although there are many other kinds of bioplastics, polylactic acid (PLA)-based packaging is the most often utilized variety. For roasters seeking for a beautiful yet environmentally responsible material to package their coffee, PLA has immense possibilities.
However, because PLA coffee bags are only recyclable and biodegradable under specific conditions, they are vulnerable to greenwashing. Roasters and coffee cafes must inform customers about the nature of PLA packaging and proper disposal as legislation catches up to the rapidly growing bioplastics industry.
Continue reading to learn how to communicate to consumers how long it takes for PLA coffee bags to disintegrate.
PLA?
The synthetic fiber business was revolutionized by Wallace Carothers, an American chemist and inventor, who is best known for developing nylon and polyethylene terephthalate (PET).
In addition, he found PLA. Carothers and other scientists found that pure lactic acid could be transformed and synthesized into polymers.
Traditional food preservatives, flavorings, and curing agents include lactic acid. By fermenting it with starch and other polysaccharides or sugars abundant in vegetation, it can be converted into polymers.
The resultant polymer could be used to create non-toxic, biodegradable thermoplastic filaments.
Its mechanical and thermal resistances are however constrained. As a result, it lost out to polyethylene terephthalate, which was more widely available at the time.
Despite this, PLA could be employed in biomedicine due to its low weight and biocompatibility, most notably as a tissue engineering scaffold material, sutures, or screws.
These substances can stay in place for a while before degrading spontaneously and without harm thanks to PLA.
Over time, it was found that combining PLA with specific starches could enhance its performance and biodegradability while reducing production costs. This contributed to the creation of a PLA film that could be utilized to manufacture flexible packaging when combined with injection molding and other melt processing technology.
Researchers anticipate that PLA will become more reasonably priced to produce, which is good news for coffee cafes and roasters.
As demand for flexible packaging rises due to customers' choice for environmentally friendly and recyclable packaging materials, the worldwide PLA market is expected to surpass $2.7 million by 2030.
Additionally, PLA can be made from agricultural and forestry waste to avoid competing with food sources.
How long does it take for PLA coffee bags to break down?
Traditional polymers made from petroleum can take up to a thousand years to decompose.
Alternately, the breakdown of PLA into carbon dioxide (CO2) and water might take anywhere from six months to two years.
Despite this, PLA collecting facilities are still adjusting to the growing bioplastics business. Only 16% of potential garbage is now being collected in the European Union.
Due to the prevalence of PLA packaging, it is possible for it to contaminate various waste streams, mix with conventional plastics, and end up in landfills or incinerators.
Coffee bags made of PLA must be disposed of at a specialized industrial composting facility where they can entirely decompose. Thanks to a certain set of exact temperatures and amounts of carbon, oxygen, and nitrogen, this process can take up to 180 days.
If PLA packaging doesn't degrade under these circumstances, the process could produce microplastics, which are bad for the environment.
Because coffee packaging is rarely constructed from a single material, the procedure becomes more difficult. For instance, the majority of coffee bags have zippers, tin ties, or degassing valves.
It might also be lined to provide an additional layer of barrier defense. Due to the possibility that each component needs to be processed separately, factors like these can make PLA coffee bags difficult to dispose of.
Using PLA coffee bags
For many roasters, using PLA to package coffee is a convenient and responsible option.
The fact that both ground and roasted coffee are dry commodities is a significant advantage. This indicates that PLA coffee bags won't need to be cleaned after usage because they are free of contaminants.
Additionally, customers can be recruited by roasters and coffee shops to help prevent PLA packaging from ending up in landfills.Customers must be aware of which recycling bin PLA coffee bags should be placed in after usage. Printing recycling and separation instructions on coffee packaging will accomplish this.
Roasters and coffee shops can encourage consumers to return their empty packaging in exchange for a discounted coffee if there are no nearby facilities to collect and process PLA.
Business owners can then make sure that used PLA coffee bags are delivered to the proper recycling center.
It might be simpler to dispose of PLA packaging in the near future. Notably, 175 nations made a commitment to stop their plastic pollution at the United Nations Environment Assembly in 2022.
As a result, more governments might make future investments in the infrastructure needed to produce bioplastics.
The movement toward adopting bioplastics is gaining momentum as plastic waste continues to devastate the environment and affect both human and animal health.
By collaborating with a coffee packaging expert, you can implement eco-friendly packaging that genuinely has an impact and doesn't cause new issues for anyone.
A variety of coffee bags from CYANPAK are available with a PLA interior. Customers can choose a totally compostable solution when it is combined with kraft paper.
We also offer packaging that is compostable, biodegradable, and recyclable that is manufactured from renewable resources, such as rice paper.
Additionally, we can utilize digital printing to customize coffee bags so that they include recycling and separating instructions. No matter the size or material, we can offer low minimum order quantities (MOQs) of packaging with a turnaround time of 40 hours and a shipment period of 24 hours.
Degassing valves that are completely recyclable and devoid of BPA are also available; they may be recycled with the rest of the coffee container. These valves not only make a product that is user-friendly for consumers but also lessen the harmful effects of coffee packaging on the environment.
