Zero Waste Sunscreen

So the number one rule here is to put your health first. There are homemade sun lotion recipes circulating the internet, but personally I wouldn’t try anything experimental without running it past a pharmacist first to check it will actually protect you against sunburn and skin cancer. Anyway, if you live in the UK, how much sun lotion-related waste are you going to produce? I’m guessing not enough to break the planet.

Many people are concerned that the ingredients in conventional sun lotions are harmful. I’m not qualified to comment on that, but the products listed here are made from a small number of recognisable ingredients.

Lush ‘The Sunblock’ Solid Sunscreen Wash

This is packaged in biodegradable cellophane. It can be applied in the shower or directly onto the skin.

It’s certainly a very effective sunblock. I have fair white skin that burns easily, and I wore this for sunbathing in hot sun without a problem. It loses points though, on price – it works out around £3 per full-body application.

Note: it melts in warm temperatures! So store it in a liquid-proof container.

Lush Sunscreen in Recycled Plastic Bottles

Lush do Sesame Suntan Lotion, (SPF 10) which also functions as a bronzer, and Powdered Sunshine (SP15). I haven’t tried either of these, but the powder looks fun.

Sunscreens In Tins

There are several brands of sunscreen available in tins which are popular with zero wasters. It’s not clear that aluminium tins are better for the environment than a plastic bottle (especially recycled plastic) so maybe don’t go out of your way to buy these just for that reason. Having said that, I have found it useful to reuse the tins for travel, and as Shade point out on their website, it is easier to use all up all the product from the bottom of a tin.  These brands also suit people who like their ingredients list simple.

Shade All-Natural Sunscreen is tested to EU standards and contains only 4 ingredients. If you buy directly from the manufacturer they promise to post it in cardboard with biodegradable filling. Their website is also a great resource on sun safety. There’s also All Good Sunscreen Butter which is available at SPF 50. Shea Alchemy Suncream SPF 15 Sun Block is one I’ve used personally, so I can tell you that this is a very effective sunblock, although a bit sticky on application.

Conventional Sun Lotion

If none of the above suits, we won’t judge you if you go for this. Just buy only what you need (beware those 3 for the price of 2 offers) and send the empty bottles to be recycled.

Zero Waste Teeth: Are Bamboo Toothbrushes Best?

It’s annoying throwing away a whole toothbrush, so what is the alternative? There are several products on the market that claim to be environmentally friendly.

Reusable toothbrushes with replaceable heads.  Source make theirs from recycled materials, or Yaweco make theirs with solar power and are cheaper. This is what I use, and it’s great. Both of these are available in health food stores or online.

Toothbrushes made from recycled yoghurt pots  which can be recycled when you’ve finished with them.

Biodegradable bamboo toothbrushes. These are popular with zero wasters, however, I am not convinced that these are more sustainable than the reusable toothbrush. This is because:

a) they don’t comply with the first rule of sustainability, which is to reduce. Bamboo toothbrushes are not designed to last – you have to keep buying and disposing of them. They will therefore need to be produced and shipped over and over again, with all the associated environmental impacts of that.

b) there is not enough information available about the way the bamboo is grown to be sure it is sustainable. How do we know that forests are not being cleared to meet the growing demand for bamboo products? How does growing large quantities of bamboo impact biodiversity and food production? There are many questions that would need to be answered before we could conclude that bamboo is sustainable.

c) if biodegradable toothbrushes end up in landfill, they will give off greenhouse gases for years.

d) bamboo toothbrushes need extra equipment to be used – ie pliers to remove the bristles when you have finished with them. If you already have some about the place, then fine, but if you need to buy extra things for the sole purpose of disposing of bamboo toothbrushes, then this will add to the impact.

e) they are more expensive than buying replacement heads for the reusable toothbrush.

I can’t be 100% certain about this, because, although I’ve searched around, I  haven’t found any research comparing the impacts of different toothbrushes. If anyone knows of any lifecycle assessments on this, please do write in. Otherwise, I’m offering my best guess.

Toothpaste

There are a number of ideas popular with zero wasters, such as toothpaste in glass jars or recipes made with bicarbonate of soda. However, I don’t feel able to recommend any of these because:

a) I am not convinced that these are good for your teeth – my dentist warns against brushing your teeth every day with bicarb, or using toothpastes that don’t contain fluoride.

b) it’s not clear that these products are necessarily better for the environment. How is a jar more sustainable than a toothpaste tube? Glass jars can be very CO2 intensive. And what about the impact of the ingredients? Toothpaste in jars are often based on coconut oil, which is not super-friendly to the environment.

The alternatives are:

Denttabs, which are teeth cleaning tablets that are crushed between your teeth. The main advantage I can see with these are that they significantly reduce resource consumption, as they are concentrate. They also contain fluoride. Apart from that, I can’t comment on how good they are for your teeth. One to discuss with your dentist.

You may want to check out Kingfisher Toothpaste, as this received a high score on the Ethical Consumer Guide and is approved by the British Dental Health Foundation.

Dental Floss

First, is it worth bothering about such a tiddly piece of waste?

Some people worry about animals or birds being strangled by waste pieces of floss (although I’m not sure how likely this is to happen if you dispose of it properly in a bin). You might also want to find a zero waste alternative if you’ve given up your waste bin and have no wish to hang on to pieces of used floss in a jar. Or maybe zero wasters are just perfectionists.

Whatever your reason, here are your options:

Dental Lace, comes in refillable capsules containing silk floss coated in vegetable-based wax. The packaging is designed to look good if you are carrying it with you.

For vegans, EcoDent  do standard floss in cardboard packaging, which can at least be recycled.

Otherwise, if sourcing zero waste floss seems like too much hassle, don’t worry. It’s just dental floss.
