The truth about bioplastics
What are Bioplastics?
There isn’t a short answer to this because the term bioplastic is a blanket term used that can cover a range of plastic-like materials.
You can argue that the term ‘bioplastic’ is cynically designed to make us think that it’s an environmentally friendly alternative to traditional plastic. However, it isn’t as simple as the name would suggest.
What should be considered is that bioplastics are essentially still plastic, and still have the potential to wreak as much havoc on the environment as their traditional counterpart.
How are bioplastics made?
Where bioplastics generally differ from traditional plastic is in the way that they are manufactured. Rather than using fossil fuels and petroleum, bioplastics are formed using renewable sources, such as corn starch or sugar cane.
There are new types of bioplastics being developed all the time. Manufacturers are gradually making the swaps for packaging, bags and medical supplies. Anything from Algae-based material to seaweed, it seems, can be utilised to create a more environmentally friendly alternative and all as versatile as traditional plastics. In summary, though, these can be split into three main groups:
Bio-based plastics:
Using bio polyesters such as polyethylene (PE) or polyethylene terephthalate (PET). These are often produced from agricultural sources, such as sugar cane or corn starch.
Bio-based and biodegradable plastics:
Using materials such as polylactic acid (PLA) or polybutylene succinate (PBS). These plastics break down in industrial composting facilities.
Fossil-based but biodegradable:
Using materials such as PBAT or PCL.
Is Bioplastic Biodegradable?
This is where it gets really complicated. There is no ‘one-size-fits-all’ answer to this.
It’s helpful here to understand the difference between biodegradable, degradable and compostable.
Perhaps it helps to consider how traditional plastic breaks down. The majority of traditional plastics are petroleum based. It takes a long time to degrade and, as it does, releases toxic microbes or microplastics into the environment. These microbes find their way into water, air, soils and can have devastating effects on the environment and biodiversity.
Biodegradable is the term generally applied to bioplastics that are, at least in part, formed of organic matter. The idea being that they can break down more quickly and without releasing harmful microplastics. This, however, is a far more complex process than we are led to believe.
Under the right conditions, it’s possible for some bioplastics to break down into carbon dioxide, water or compost. It’s important to note that there need to be some fairly specific circumstances in order for this to really work.
In the first instance, a bioplastic needs to be, at least partially bio-based
Secondly, you cannot simply plonk your bioplastic on your home compost and hope for the microorganisms to get to work. They need to be disposed of correctly and require strict industrial conditions in order to break down. If these conditions are not met, then bioplastic has just as much chance of ending up in landfills or polluting the oceans as any traditional plastic.
And lastly, there are some bioplastics that will still release toxic microbes in the degrading process.
So, whilst in theory, a bioplastic can be a better option than petroleum-based plastic, it’s more complex than just a straight swap for it to really make an impact. Realistically, there is so much research to do should you want to really find a bioplastic that could be considered environmentally friendly, that it makes sense to avoid them altogether.
Is bioplastic recyclable?
The honest answer to this question is ‘sometimes’. Again, the issue here is the blanket term ‘bioplastic’ being applied to a wide range of materials. Whilst some are specifically designed for recycling, the resources to do so simply aren’t there. Recycling plants are not always equipped with the specifics required of many types of bioplastic.
In order to really make an impact, there needs to be a meaningful discussion about how we, as a country and a global community, deal with waste. Without this, the switch to bioplastics by large conglomerates and companies is little more than Greenwashing.
Is bioplastic better for the environment?
Yes, if managed properly. However, as seen from the above, this is not as simple as it would first appear. Once you begin to dig a little deeper, you realise that ‘compostable’ doesn’t necessarily mean what you might think.
If you can ensure that the above criteria are met, then yes, bioplastics are going to be much better for the environment in the long run. However, it’s a bit of a leap to suggest that this is going to solve the plastic waste problem.
What is the solution to plastic Waste?
So, what is the solution to plastic waste? Before it all gets too overwhelming, there are ways that you can help fight the problem of plastic waste.
Here are a few tips that can help:
- Reduce! Start small - you can’t solve the plastic waste issue all by yourself. Like any big problem, it’s helpful to break it down. Start by making small eco swaps. For example, pick a room, the kitchen, the bathroom, garden etc. Think about where you can replace single-use plastics. A bag for life, a reusable water bottle (Here’s looking at you Joe Lycett!) or, of course, a tube of toothpaste!
- Reuse! One of the things we love at Truthpaste is seeing the creative ways that you reuse our jars! Everything from storing food to decorating as gifts, we’ve even seen them used to hold furniture together! Reusing is one of the easiest ways to impact your carbon footprint and you can get seriously imaginative!
- Recycle! Look for packaging that is easily recyclable. You can find an increasing number of shops popping up that are completely plastic-free. Glass, for example, can be recycled indefinitely with no loss to the quality. If using bioplastics, look into how easily recyclable they actually are and consider what alternatives are out there.
At Truthpaste we have always aimed to produce a zero-waste and plastic-free product. We feel strongly that sustainability shouldn’t be a gimmick but a goal. Rather than simply replace plastic with bioplastic we feel that it is better and more environmentally sound to avoid plastic altogether. Our HQ operates on a zero-to-landfill approach and we are constantly looking at ways that we can make as little impact on the planet as possible.
The journey to a plastic-free health and beauty regime can take some time and a lot of research. However, we are proud to be an easy and simple swap to achieve that goal.

from 767 reviewsLove the taste of this paste and it seems to really get the mouth tingly clean. I also got the mouthwash and that's also very FRESH. Thanks for not having flouride, which so many 'alternative' toothpastes seem to include.
Nice flavour and not too strong
I have used the mouthwash for 2 weeks now and am really enjoying the fresh and minty sensation. I love the ingredients and it just makes my whole mouth feel extra clean. I will definitely order more as the bottle will probably only last for another week or so.
First time purchasing this one. so far i am happy with it.
Absolutely outstanding tbh no more pain it really disappears after 4 day’s delighted
Love this peppermint and wintergreen.. tastes great and works!! Love it Thank you 😊
Excellent product...works really well...love it
I have loved using this product. It makes the mount feel really fresh and my teeth
super clean, without any nasty ingredients included!
Aww absolutely love this bundle I had this sore gum so thought to order the bundle to try , not gonna lye it’s superb feels and taste so natural ,very cleansing and the sore gum is better , love the mouth wash too it stays fresh for a long while , the bamboo floss dosent slip unlike those waxy ones used in past ! So not going to buy anything else apart from this range even better it’s made in Brighton 🤩
I really love this toothpaste. It soothes my gums, has helped with sensitivity and leaves my mouth feeling really fresh. All without the nasties. Will buy again.
Since using Truthpaste I’ve noticed a change in how my mouth and teeth feel. Cleaner teeth, no more bleeding gums and my teeth feel stronger 😁
Been using this for around 2 weeks no unpleasant after taste like other toothpastes mouth feels fresh and jar will last a fair while Will definitely order again
I have suffered from tooth sensitivity for about a year - dentist couldn’t help suggest anything other than to quit sugar, but a girl neeeeeeeeds some chocolate at certain times, ya know? Within the first brush I felt a difference! So glad I made the switch!
Been using this toothpaste for a while now. Absolutely love it!
