TRYING to reduce your waste in everyday life can be complicated enough, but when travelling, a few key reusable items can make all the difference between a wasteful trip and a more sustainable one.
These zero waste travel essentials will quickly become a jet-setting staple, as important to pack as your swimwear or ski gear.
We know that travel is inherently bad for the environment, from daily car travel to the massive carbon footprint our air journeys leave us with.
So at least having a zero waste travel kit can help us minimise our waste - and our plastic use - wherever we go.
The key zero waste travel essentials every traveller needs are toiletries, reusable cups and bottles and cutlery for on the go meals.
In terms of toiletries, look for a bamboo toothbrush as an alternative to a plastic one, as well as packaging-free products.
From shampoo bars to soap to cleansing bars to menstrual cups, there are plenty of reusable zero waste travel essentials to stock up on now.

1. Best zero waste travel essentials: Ethique Face, Hair & Body Trial Pack
New Zealand brand Ethique is the go-brand for solid, zero-waste beauty bars.
This starter set has solid mini shampoo, conditioner, cleanser and body butter, and is formulated for dry skin, which often happens when travelling.
You'll also find normal and oily skin ranges.
Fans really like them - especially those who have tried other solid shampoos that just don't work as well.
'I am very impressed with all these products. The shampoo and conditioner have left my hair shiny and smooth. I have used loads of solid shampoos in the past but they have all left a residue. Not this one, it rinsed out easily.
'The solid cleanser is also lovely and lathers well. I loved the solid body butter. I let it melt in my hands and rubbed it on my body. A tiny amount is all you need. My skin felt hydrated but not oily', writes a customer.
2. Best zero waste travel essentials: Bambaw Bamboo Cutlery Set
This fantastic cutlery set with roll-up jute pouch won't take up a ton of room in your suitcase - but it will save you using disposable straws and utensils.
The bamboo set includes a spoon, fork, knife and straw, as well as a straw cleaner.
'Nicely designed carry pouch. Good sturdy cutlery. Really handy for packed lunches, picnics or just carrying in your bag just in case', writes a happy customer.
3. Best zero waste travel essentials: Moon water bottle
Designer water bottles may be all the rage, but for travel purposes you want one that's about function as much as fashion.
Moon water bottles are brilliant; they look good, keep drinks hot for 12 hours and cold for 24.
Plus, they're about half the price of some other bottles out there, which should give you peace of mind when travelling.
Fans love them so much, most of them are return buyers.
4. Best zero waste travel essentials: Anthropologie Anya travel tumbler
Middle-of-the-night flights. Jet lag. Travelling delays. These can only mean one thing: coffee is going to be an essential on your trip.
A reusable coffee cup will save you throwing away disposable cups, and you want a design that's hardwearing and inexpensive.
This Anya travel tumbler from Anthropologie ticks every box: made of stoneware, it'll be fairly scratch-resistant and durable.
The size and shape works well for housing soups on the go, too.
5. Best zero waste travel essentials: Zebra Woo bamboo toothbrushes
A bamboo toothbrush is better for the planet than a plastic alternative, and this set of four should last you the year - or work well for multiple family members (each toothbrush has a different design).
The toothbrushes have charcoal-activated bristles, and the set includes charcoal dental floss, in its own pouch.
An eco-recycled carton case is perfect for toting your brush around, wherever you are in the world.
6. Best zero waste travel essentials: N Newkoin reusable shopping bags
From market stalls with fresh fruit and veg to getting some souvenirs, shopping is a fun part of the travel experience.

This set of 12 features a few different sizes of drawstring bag, which can really be used for anything and everything (abroad or at home (you can even use them to hold dirty washing when travelling).
As one fan writes:
'I bought them because I'm trying to reduce as much plastic and trash in general from my life that I can, and it seemed like a really good idea to have reusable produce bags.
