Are laundry sheets better for the environment than a bottle?

You do the laundry every week, year in year out. With a habit that comes round that often, a small change counts for a lot. The only question is which change, because not everything that sounds green makes the same difference.

Short answer

You gain on four counts: plastic, waste, water and energy.

The plastic goes, because neither the packaging nor the product contains any. Your waste shrinks, because there is no empty bottle left to throw out. You use less water, because a concentrated sheet needs less product and less rinsing. And you save energy, because the sheets wash cold as well. One thing changes in your routine: what goes into the drum.

Why does the plastic disappear from your laundry routine?

Because the bottle goes, and the cap goes with it.

iZi-Wash Sheets replace liquid detergent with a single sheet, and neither the packaging nor the product itself contains plastic. What you do not buy, you do not have to throw away: no bottle, no cap, no sticky remnant in the bottom. Have a look at the iZi-Wash Sheets with 100 washes.

That sounds small as long as you are thinking of one bottle. Work it out over a year of laundry and you are talking about the pile that normally builds up in your cupboard every month or two, and after that in your bin.

What you buy	Bottle of detergent	Laundry sheet
Packaging	Plastic bottle with a cap	Paper packaging, plastic free
What you carry home	Mostly water	Only the detergent itself
Dosing	Measuring cap, easy to overdo	Pre-dosed sheet
What is left over	An empty bottle	Nothing in the drum, and the packaging is biodegradable

How much waste does that save at home?

Every bottle you do not buy is a bottle you do not have to throw out.

Add that up over a year of laundry and you will see the difference in your bin, or in your bin bag. The sheets come in paper packaging and are biodegradable, with no harmful chemicals.

The packaging does not even need to go in with the paper recycling: tear it into pieces after use and put it in the soil. That is the only packaging in your cupboard you can do that with, and it is the simplest proof going that there is no plastic in it.

Something that often gets overlooked: overdosing is waste too. Detergent you use too much of simply rinses out of your machine unused. With a pre-dosed sheet, that cannot happen.

How do you save water with them?

In two places at once, and you do not see the second one.

In the machine you need less product per wash, because the sheets are concentrated, and less product means less water to rinse it back out of your clothes.

Before that, in production and transport, less water is needed too, because you are no longer moving bottles of water around. That is the invisible half of the bill: the water that sat in the bottle before it ever reached your cupboard.

Why washing cold saves the most

By far the most energy in a wash goes on heating the water.

Not on turning the drum, not on the pump. On the heating element. That is why the temperature dial is the one that wins you something, and not the programme.

The sheets are made to work effectively in cold water as well and they suit eco cycles, so you can safely turn that dial down a few degrees without giving anything up on clean.

An eco cycle taking longer feels contradictory. But time costs almost nothing, and heating does. A programme that runs longer at a lower temperature uses less electricity overall than a short hot wash.

Dry your washing outside when the weather allows and you save again, because after the heating element a tumble dryer is the biggest consumer in the laundry room. And your clothes freshen up naturally.

What does it save in storage and transport?

A box of sheets takes up a fraction of the space of a bottle.

You notice that in your cupboard straight away, where several packs fit in the space of one bottle. It is the sort of difference you only see once you take the bottle out.

And it counts right through the chain: because the sheets are compact and light, CO2 emissions in transport are far lower than for ordinary detergents. A lorry carrying liquid detergent is for the most part carrying water.

What is not in them?

The list is shorter than the list of what is in them, and that is the point.

1
No phosphates and no optical brighteners. Optical brighteners do not make white cleaner, they make it look whiter.
2
No bleach and no aggressive chemicals.
3
No plastic, not in the product and not in the packaging.
4
Vegan and not tested on animals.
5
Biodegradable.

The sheets dissolve completely during the wash, so no residue is left in your fibres. Kind to your clothes, kind to your skin and kind to the water leaving your machine.

What a laundry sheet does not change

The honest limit, because that is what makes the rest believable.

Your washing machine still uses water and electricity. A different detergent changes nothing about the volume of a wash or about the machine you happen to have standing there. What you gain with the temperature dial and with a full drum, no detergent gains for you.

And fibres that come loose from synthetic clothing during the wash come from the textile, not from your detergent. If you want to do something about that, it sits in what you buy and how often you wash it, not in the sheet.

What a laundry sheet does do is make the part that is genuinely in your hands smaller: the packaging, the transport, the dosing and the option to wash cold. That is a real part, and it is not the whole picture. That is a difference worth knowing before you choose.

What to look at when you compare detergents

Four questions you can ask of any pack or any bottle.

Environmentally friendly is not a protected term, so the front of the pack says whatever the maker would like it to say. The back and the weight tell you more.

How many washes are in it? Never compare on price per bottle or per pack, but on price per wash. That is the only figure that makes two different formats comparable.

How much does it weigh per wash? Weight is almost entirely transport. The less that has to travel for the same laundry, the smaller that part of the bill.

What is left when it runs out? An empty bottle, a plastic bag or nothing. That is the question your bin answers a year later.

Do you have to dose it yourself? Anything you measure by hand, you measure generously sooner or later. Pre-dosed is not only easier, it is also more economical.

What does it do for your wallet?

More sustainable and cheaper happen to coincide here.

Because the sheets are concentrated and pre-dosed, you use less product per wash and waste nothing. You no longer overdose, so you buy detergent less often.

Households that switch to reusable cloths and concentrated products with iZi-Clean save €100+ a year on cleaning products. That is not a separate exercise, it is the result of throwing less away.

How does this fit the rest of your household?

Cleaning more sustainably works on the same principle.

Fewer throwaway products, more things you use again. Washable microfibre cloths from iZi-Clean fit that perfectly, because you simply wash them in with your normal load and use them again.

There is a practical connection in it as well: the sheets leave no residue in the fibres, so your cloths keep their absorbency. A cloth full of fabric softener takes up less water, and you notice that on the windows straight away.

A clean machine belongs in that picture too. Soap residue and dirt that build up cost you extra washes in the long run. How to prevent that is in washing machine smells? this is how the smell goes in five steps.

How much effort is switching?

Less than you think, and you do not have to throw anything away.

You put a sheet in the machine, add your washing and start the programme. No measuring, no spills, and nothing else about your routine changes.

Order one pack and finish your bottle at your own pace: once it is empty, you simply will not buy another. Throwing half a bottle away to become more sustainable is exactly the opposite of the point.

Frequently asked questions

Do laundry sheets contain plastic?

No. Neither the packaging nor the product itself contains plastic. So no bottle and no cap end up in your bin.

What do you do with the packaging?

It is fully biodegradable. Tear it into pieces after use and put it in the soil.

How do laundry sheets save water?

The sheets are concentrated, so you use less product per wash. Less product also means less water to rinse it back out of your clothes. In production and transport it saves water too.

Do laundry sheets work in cold water?

Yes, they are designed to work effectively in cold water as well and they suit eco cycles. Heating the water takes most of the energy of a wash, so that is where the gain is.

Why does an eco cycle take so long?

Because it runs longer at a lower temperature. Time costs almost nothing, heating does. Overall that uses less electricity than a short hot wash.

Why does it make a difference in transport?

A bottle of detergent is largely water that gets driven the length of the country. Laundry sheets are compact and light, so CO2 emissions in transport are much lower.

What is not in laundry sheets?

No phosphates, no optical brighteners, no bleach and no aggressive chemicals. The sheets are vegan, not tested on animals and biodegradable.

Does any residue stay on my clothes?

No. The sheets dissolve completely during the wash, so nothing is left in the fibres. You notice it on microfibre cloths you wash in with the load as well: they keep their absorbency.

Does a different detergent solve the microplastics problem?

No. Fibres that come loose from synthetic clothing during the wash come from the textile, not from your detergent. The gain there sits in what you buy and how often you wash it.

Does it save me money as well?

Because the sheets are concentrated and pre-dosed, you use less product per wash and waste nothing. Counted over a year, that adds up.

Do I have to throw my bottle of detergent away to switch?

No, and that would be the opposite of the point. Order one pack and finish your bottle at your own pace. Once it is empty, you simply will not buy another.

How do I compare two detergents fairly?

On price per wash, not per bottle or per pack. Beyond that, look at the weight per wash, what is left when it runs out, and whether you have to dose it yourself.

Can I wash my microfibre cloths with them?

Yes, and the difference is easy to notice. Because no residue is left in the fibres, your cloths keep their absorbency.
