In the past, many traditional tea bags contained polypropylene, a sealing plastic that prevents them from being recycled. However, an increasing number of tea brands have moved away from plastic, opting for plant-based bioplastics that are recyclable and biodegradable. In June 2021, Aldi joined this movement by pledging to remove single-use plastic from its own-brand range of tea bags. This commitment means switching from oil-based plastic sealing to biodegradable materials, with the goal of making all tea bags 100% biodegradable and plastic-free.

What You'll Learn
Aldi tea bags are now plastic-free
Aldi has committed to removing single-use plastic from all its own-brand tea bags. In June 2021, the supermarket confirmed it was removing single-use plastic from its tea bags, with the changes rolling out across the country by the end of that year.
Aldi's tea bags are now made from industrially compostable plant-based plastic PLA, meaning they are 100% biodegradable and can be added to compost bins. This switch is part of the brand's ongoing sustainability efforts and will help reduce its environmental impact.
Prior to this change, Aldi's tea bags, like many traditional tea bags, contained polypropylene, a sealing plastic that made the bags non-recyclable and non-biodegradable. Now, all of Aldi's own-brand tea, including decaffeinated and fruit and herbal infusions, are made from PLA and are industrially compostable.
This move towards plastic-free tea bags follows similar actions by other supermarkets, including Sainsbury's and Lidl, and is in line with Aldi's pledge to halve the volume of plastic packaging it uses by 2025. The supermarket has also committed to having all own-label products be recyclable, reusable, or compostable by 2022 and branded products sold at Aldi by 2025.

They switched to biodegradable materials
In June 2021, Aldi announced its commitment to removing single-use plastic from its own-brand tea bags by the end of the year. The company's tea bags were previously sealed with oil-based plastic, which was replaced with biodegradable materials. This switch meant that all of Aldi's tea bags became 100% biodegradable and could be added to compost bins.
Aldi's decision to remove plastic from its tea bags was part of a broader effort to reduce its environmental impact and provide more sustainable options for its customers. The company had previously pledged to halve its plastic packaging by 2025, aiming to eliminate 74,000 tonnes of plastic packaging over four years. Aldi's commitment to sustainability also included plans to make all own-label products recyclable, reusable, or compostable by 2022 and to achieve the same for branded products sold at Aldi by 2025.
The switch to biodegradable materials for tea bags was not an isolated incident at Aldi. Other supermarkets, such as Sainsbury's and Lidl, also made similar transitions. Lidl, for instance, confirmed that its own-brand tea bags were completely biodegradable, primarily made from polylactic acid (PLA), a compostable bioplastic.
The shift towards biodegradable tea bags was driven by consumer demand and the growing awareness of hidden plastics in everyday items. Many traditional tea bags used polypropylene, a sealing plastic that prevented them from being recycled. However, with increasing environmental consciousness, several tea bag brands moved away from plastic, opting for plant-based bioplastics that are both recyclable and biodegradable.
Aldi's tea bags are now free from single-use plastic and are made from industrially compostable plant-based plastic PLA. This change has been well-received by consumers who are increasingly seeking eco-friendly and sustainable alternatives. Aldi's commitment to sustainability and its response to consumer demands have positioned it as a leader in environmental responsibility among UK supermarkets.

Oil-based plastic sealing was previously used
The transition to biodegradable tea bags means that consumers can now dispose of Aldi's tea bags in their compost bins, contributing to a more sustainable waste management approach. This change aligns with the growing consumer demand for eco-friendly alternatives to traditional tea bags, which often contained hidden plastics.
The presence of oil-based plastic sealing in tea bags has been a concern for environmentally conscious consumers. With the removal of this sealing plastic, Aldi's tea bags are now free from single-use plastic, addressing the issue of non-biodegradable waste. This shift towards biodegradable materials is a positive step towards reducing the environmental impact of tea bag consumption, offering consumers a more sustainable option for their daily cup of tea.
Aldi's decision to switch to biodegradable tea bags is a response to consumer demand for more sustainable products and the company's commitment to reducing its environmental footprint. By eliminating oil-based plastic sealing, Aldi has taken a significant step towards making its tea bags eco-friendlier and contributing to a more circular economy. This change also highlights the power of consumer voices in driving sustainable changes in the products they use, encouraging other companies to follow suit and make similar environmentally conscious decisions.

PLA is a bioplastic
In June 2021, Aldi announced its plans to remove single-use plastic from its own-brand range of tea bags. The UK's fifth-largest supermarket committed to switching the oil-based plastic sealing of the tea bags to biodegradable materials, making all tea bags 100% biodegradable.
Polylactic Acid (PLA), a bioplastic, is one such biodegradable material. PLA is derived from renewable resources such as maize or sugar cane. The fermentation of starch or sugar extracted from these resources results in the production of lactic acid, which is then transformed into a monomer: lactide. The polymerization of lactide is what allows the manufacturing of PLA.
PLA is one of the first renewable plastics capable of competing with conventional plastics in terms of performance and environmental impact. It emits three times less CO2 and is already available on the market. PLA is also the most widely used filament for 3D printing due to its biodegradable nature.
However, it is important to note that PLA is not without its disadvantages. It can be more expensive than conventional plastic due to the number of steps required in the production process. Additionally, its compostability has historically been limited to industrial installations due to the requirement for high and constant temperatures. Furthermore, PLA may not fully biodegrade in marine environments, presenting a danger to marine life.

PLA is industrially compostable
In June 2021, Aldi announced that it would be removing single-use plastic from its own-brand range of tea bags. The company pledged to make all of its own-brand tea bags, including decaffeinated and fruit and herbal infusions, free of plastic and biodegradable by the end of the year.
Aldi's tea bags are now made from PLA, a bioplastic made from plant-based resources like corn, cassava, and sugarcane. PLA stands for poly(lactic acids), and it is one of the most commonly used bioplastics. It has similar functionalities to conventional plastic and is considered to be compostable, biodegradable, and recyclable.
However, it is important to note that PLA is only compostable under specific high-temperature conditions that cannot be found in nature. It is certified as industrially compostable to Australian and European Standards (AS4736 and EN13432), which means that under commercial composting conditions, PLA will break down within twelve weeks. This makes it a more environmentally friendly choice than traditional plastics, which can take centuries to break down and often end up as microplastics.
While PLA is a step in the right direction for companies like Aldi, it is not a perfect solution. Recent research has shown that PLA might not be as environmentally friendly as initially thought. For example, a study found that PLA did not show any signs of degradation after spending 428 days under natural marine conditions. Additionally, the recycling infrastructure for PLA has not been fully developed yet, so recycling PLA is not a widely available option at the moment.
