10 Sustainable Materials to Look Out for in 2021

Sustainable Materials: Green Bamboo Stems

With single-use plastic seeing bans the world over, it’s never been more important to explore sustainable materials as alternatives to traditional materials. 

But, it’s also never been more difficult to make the right choice – every company claims their material is perfectly sustainable and often they’re not. 

That’s why today we’re going to show you 10 sustainable materials to look out for in 2021, so you can make the right choice when it comes to picking sustainable products.

#1: Bamboo

Bamboo is a common sustainable material choice for manufacturers and companies and nowadays you’ll find all sorts of products made from Bamboo.

Bamboo’s top attributes

  • Cultivation requires no pesticides
  • It regenerates from the root, so it doesn’t require re-cultivation 
  • Bamboo is the fastest growing plant on the planet! 
  • It is biodegradable

Bamboo can be grown with ease, making it a top pick for a sustainable material in it’s raw form.

By contrast, Viscose (the textile form of Bamboo) is made with harsh chemicals and requires lots of water and energy to make, so it is not always so great. 

When shopping for fabric Bamboo products in the form of t-shirts, socks, boxer shorts etc. make sure to opt for Lyocell, which is made without producing chemical waste.

#2: Hemp

Since many countries have started lifting their ban on growing Hemp, it has increased in popularity.

It’s quickly becoming an everyday sustainable material, used in food products, fabric products and even as a green building material.

Check out this short video on Hemp and sustainability by Pildora:

Hemp’s top attributes

  • Hemp is a weed (no pun intended), so it grows readily without water or pesticides
  • It produces far more pulp per plant than the equivalent amount of timber
  • Doesn’t require much space to grow
  • Its biodegradable
  • Virtually every part of the plant can be used, so it’s very low waste

If you’re looking for an alternative to less sustainable materials like cotton, Hemp is a great choice thanks to it’s impressive list of eco-credentials. 

#3: Cork

Cork is certainly a lot less common than Bamboo and Hemp but it’s a very sustainable material nonetheless.

It is now starting to see usage in making a bunch of consumer products like wallets, footwear, bags and more. This informative video takes a deeper dive into the green attributes of Cork and some of it’s common uses:

Cork’s top attributes

  • Cork is gathered from the bark of a tree and regenerates after harvesting
  • Cork oak forests are biodiversity hotspots
  • It is biodegradable

Cork is becoming popular thanks to its strength and durability, as well as it’s sustainable characteristics, so it’s worth trying if you get the chance.

#4: Adobe

You may have not heard of adobe but it is a building material that’s been used for centuries and is pretty commonplace in some parts of the world.

In its simplest form, adobe is made from earth, water and dung/straw which may sound unimpressive (or even a bit gross). But, these common and eco-friendly ingredients make it one of the most sustainable building materials around!

Adobe’s top attributes

  • Adobe is very durable (some of the world’s oldest buildings are made from adobe)
  • All of it’s ingredients are readily available
  • Adobe bricks are naturally baked in the sun so require no energy to bake

Now, for most of you reading this, using adobe may not be that applicable to day to day life. However, if you’re taking on a construction project or are just interested in adobe and it’s usage you can check out this great resource.

#5: Pinatex

As veganism grows in popularity, more consumers are looking for plant-based alternatives to animal products. This has lead to a rise in interesting materials like Pinatex.

Pinatex is a plant based leather made from, you guessed it, Pineapple. To see just how pineapple leaves are turned into soft and supple leather take a look at this video below:

Pinatex’s top attributes

  • It uses a raw material that would otherwise go to waste
  • Its vegan-friendly
  • It is softer and versatile like traditional leather.

Pinatex is made from a waste agricultural byproduct (Pineapple leaves) and a few other choice ingredients, making it a sustainable and low waste alternative to animal and petroleum based leather.

#6: Coconut

Coconut is no longer just a food product but is now seeing usage in a variety of products including scouring pads, bowls, cutlery and even as a sustainable building material.

To see how a humble old Coconut can be transformed into a beautiful bowl watch the video below:

YouTube video

Coconut’s top attributes

  • The Coconut shell can be used in its entirety, making it zero waste
  • No additional chemicals, such as glue, are needed for Coconut as a construction material, which makes it a ‘low to no’ toxin product 
  • It’s biodegradable

As manufacturers are looking at more uses for this wonder material, it’s becoming more common place. Keep your eyes peeled for coconut products in 2021!

#7: Bio-plastics

Bio-plastics are a hot material at the moment and many single-use plastic items are now being manufactured from all manner of bio-plastics in place of traditional petroleum based plastics. 

But what are bio-plastics? Bio-plastics are semi-synthetic plastics that are derived from plants, including corn, sugar beets and castor beans.

If you’re scratching your head as to how these materials can be transformed into plastics, this video explains everything you need to know!

Bio-plastic’s top attributes

  • They are created without use of fossil fuels.
  • Bio-plastics are just as robust as their fossil fuel equivalents.
  • They may be compostable and biodegradable.

BUT a word of caution: Bio-plastics are not without their problems. Much like other plastics, they’re often non-biodegradable and produced using an abundance of harmful chemicals. 

My best advice is to only use bio-plastics as an alternative to petroleum plastics but always opt for reusables and other sustainable materials where you can.

#8: Stainless Steel

You’re no doubt already familiar with Stainless steel as a very sustainable material, but it deserves a place on this list nonetheless.

Stainless steel is ideal for items that you’re planning to use and keep for years to come. Think reusable water bottles, cutlery, reusable straws and other cookware.

It is even being used in place of Carbon steel, as a more sustainable (and fully recyclable) material for large scale items like bridges:

Stainless steel’s top attributes

  • It is produced toxin free, which is why it makes a great choice for items like cutlery and even surgical implants.
  • Stainless steel is super durable and with care, items can last 100s of years
  • It doesn’t degrade during recycling, which means it can be recycled 100s of times.

Looking at the points above it’s clear stainless steel is a great material to choose when it comes to products you plan on having with you for life!

#9: Recycled Plastics

Plastics have been vilified in recent years and with good reason: they’re littering beaches and oceans and becoming a real hazard to wildlife. 

One of the biggest problems we face with plastic waste is what to do with all the plastic we’ve already produced. That’s where recycled plastics come in.

Loads of products are now made with recycled plastic, including shoes, bags, cookware and more.

Recycled plastic’s top attributes

  • Stops millions of tonnes of waste from entering the environment.
  • It conserves natural resources and energy
  • Saves landfill space

Recycled plastics are part of the solution to the masses of plastic waste that would otherwise be in landfill or littering the environment and the products are pretty great too!

However, don’t forget that recycled plastic products can’t always be recycled again, so it may be best to opt for another material if you’re choosing a product with a limited lifespan. 

#10: Straw

Yes straw, the very same straw that’s used as cattle feed can also be used in a number of applications including clothing, bio-fuel, packaging, paper and more. 

YouTube video

Straw’s top attributes

  • It’s cheap and readily available
  • Straw is biodegradable
  • It’s strong when woven

You may not see it in every shop, or on every shelf like some of the other materials on this list, but it’s growing in popularity every day. Straw is becoming more and more common as a replacement for single-use plastics. 

If that video has inspired you to switch to straw, keep an eye out for it in 2021!

Frequently Asked Questions

What makes a material sustainable?

There're many components that go into how sustainable a material is. In a nutshell, a material is sustainable if it can be produced with minimal impact on the planet and disposed of with minimal impact too

Which sustainable material should I choose?

This depends on what your product would be used for. If you’re opting for a product that will need to be disposed of soon, you’ll want to look at materials that are compostable and biodegradable. If you’re looking for a product that you’ll need for years, you’ll want to look at sturdier materials like stainless steel.

Where do I find products made with sustainable materials?

Luckily products made with sustainable materials have never been more accessible! You can often find substitutes for less sustainable materials by searching for “sustainable alternative to” and inserting the product you’re looking for in google. Just make sure to do a bit of research on the material and company before purchasing.
