Refills and Reusables

Most zero waste lists are alphabetical, or organised by room, or just everything someone could think of dropped into a single bulleted dump. None of that tells you where to start. This is the version that does.

Every swap here has been checked for actual impact and actual performance. They’re in order, highest return first. The deep-dive articles are linked where the detail lives.

How to use this list

Work top to bottom. Don’t buy anything new to make a swap happen. Use what you already own until it runs out, then replace it with the better version. The most sustainable product is always the one you’ve already bought.

If a swap isn’t on this list, it’s either in the “not ready yet” section at the bottom, or it’s one of those things that sounds important but isn’t.

Start here. The highest-return swaps

These three come first, regardless of which room you’re starting in. Between them they cover the highest-volume, most repeatable categories of household plastic.

01. Switch cleaning products to concentrated refillable formats

A refillable glass or aluminium bottle plus concentrated tablets or drops replaces an entire under-sink cabinet of single-use plastic. A 2023 Which? review found concentrated formats use substantially less plastic and far less water than ready-mixed sprays, because you’re not shipping water around the country. For most households this is the biggest single swap. Full guide: eco swaps for home. Shop: Refillable Multi-Surface.

02. Switch laundry detergent to laundry sheets

Detergent bottles are bulky, heavy, almost never recyclable, and replaced constantly. Laundry sheets in cardboard packaging do the same job and produce none of the packaging. Modern formulations work at all temperatures in all machine types. Shop: Refillable Laundry.

03. Buy loose fruit and vegetables where you can

Food and drink packaging made up 83% of the plastic items counted in the 2022 Big Plastic Count, the largest UK household plastic survey to date. Fresh produce is one of the biggest single categories within that. Bring your own bag. Buy loose where available. Choose cardboard or paper over plastic film where it’s not. Full guide: eco swaps for food and drink.

The bathroom

04. Shampoo bar (syndet, not soap-based)

One bar replaces two to three plastic bottles. The key: buy a pH-balanced syndet bar, not a traditional soap bar. A 2014 review in the International Journal of Trichology found syndet cleansers are gentler on the hair cuticle and scalp than soap-based formulas. Give any new bar three to four washes before judging. Full guide: eco swaps for beauty.

05. Reusable cotton rounds

One of the fastest payback swaps on the list. A pack of ten reusable cloth rounds replaces hundreds of disposable cotton pads over a year. Machine washable. No adjustment required.

06. Refillable deodorant

Refillable aluminium deodorants with replaceable inserts perform as well as conventional roll-ons for most people. Higher upfront cost, lower ongoing cost and waste. Shop: Refillable Deodorant.

07. Bamboo toothbrush

The handle composts, the nylon bristles still go in general waste. Imperfect, but a clear improvement on a fully plastic brush replaced every three months.

08. For activewear, look for OEKO-TEX Standard 100

Testing reported by Environmental Health News in 2022, using an EPA-certified lab, found that around one in four pairs of popular leggings had detectable fluorine (a PFAS indicator). Three in four showed none. OEKO-TEX Standard 100 screens for these. Natural fibres work for lower-intensity exercise where moisture-wicking matters less. Full guide: eco swaps for fashion.

The kitchen and food shopping

09. Reusable water bottle and coffee cup

The most avoidable single-use plastic in most people’s daily lives. One good bottle removes the category. Shop: Water Bottles.

10. Glass, cardboard or aluminium over plastic for pantry staples

Passata in a carton rather than a plastic bottle. Tinned tomatoes rather than plastic pouches. Nut butter in a glass jar rather than a plastic tub. Identical product inside. The packaging decision costs no extra effort at the point of purchase. Shop: The Pantry.

11. Beeswax wrap for most uses

Cling film is almost never recyclable by UK councils. Beeswax wrap covers bowls, wraps sandwiches, keeps cut vegetables fresh. Doesn’t work for raw meat, needs cold water for washing. Otherwise, a direct replacement.

12. Compostable kitchen sponge

Research published in 2022 in Science of the Total Environment estimated that a single synthetic kitchen sponge can release millions of microplastic fibres over its lifetime, mostly into wastewater. Loofah, wood-pulp cellulose and sisal scourers do the same cleaning job without the plastic. Low cost, no adjustment.

13. Buy in bulk for staples you use reliably

Oats, rice, lentils, flour. Larger bags produce less packaging per portion. Many zero-waste shops also offer loose options. Shop: Bulk Pantry.

14. Reusable produce bags

Lightweight mesh or cotton. Replaces the roll of thin plastic bags. Washes easily, lasts for years.

Cleaning and laundry (beyond the two big wins above)

15. Washing-up liquid: switch to concentrate or a solid bar

Concentrated washing-up liquid diluted into a refillable bottle reduces bottle turnover considerably. A solid bar eliminates it entirely. Shop: Refillable Washing Up.

16. Dishwasher tablets in plastic-free packaging

Most conventional tablets come individually wrapped in plastic film inside a plastic tub. Cardboard-boxed or compostable-wrapped alternatives perform comparably.

17. A Guppyfriend bag for washing synthetics

Catches microplastic fibres shed during washing before they enter wastewater. Works with any machine, any detergent. Not a fix at source, but a meaningful reduction.

Fashion and wardrobe

18. Buy secondhand first

For jeans, knitwear, outerwear, basics, the UK secondhand market is deep. Vinted, Depop, eBay, charity shops. Essentially no manufacturing footprint beyond transport.

19. Wear things more

The biggest environmental lever in fashion isn’t what you buy. It’s how many times you wear it. WRAP’s research consistently finds that extending the active life of a garment by nine months reduces its carbon, water and waste footprints by around 20 to 30%. Cost per wear is the right frame: a £90 well-made item worn 90 times costs £1 per wear. A £15 fast-fashion equivalent worn five times costs £3 per wear.

The most sustainable product is always the one you’ve already bought.

20. When buying new, look for OEKO-TEX, GOTS or named factories

The signals that a brand has thought beyond the label.

21. Wash at 30 degrees and line dry

A life-cycle analysis by WRAP found that the use phase (washing, drying, ironing) accounts for a meaningful share of a garment’s total carbon footprint. One of the lowest-effort reductions available.

The ones that aren’t ready yet

Some things get asked about a lot. These are the honest answers.

Crisp packets and snack packaging. Almost all of it is plastic film or foil-laminate, collected by almost no UK councils. TerraCycle runs drop-off schemes for some brands. Not yet a consumer problem with a consumer solution.

Mascara, most foundations, and multi-component cosmetics. The packaging on these hasn’t been solved at scale. Buy less, use products fully, use TerraCycle points where available.

Compostable bin liners for general waste. They need industrial composting conditions to break down, which most UK councils don’t provide. Recycled-content plastic liners are the more honest swap for general waste until kerbside infrastructure catches up. Compostable liners do work for food caddy liners going to food waste collection.

Textile recycling into new garments. According to the Ellen MacArthur Foundation, less than 1% of the material used to produce clothing is recycled into new clothing, because the fibre-to-fibre infrastructure doesn’t yet exist at scale. Donation and secondhand keep clothes in use. Actual closed-loop recycling is not a real option for most consumers yet.

You now have the list in the right order. Next time something runs out, you know exactly what to replace it with.

FAQs

The headline number that is supposed to motivate you is the 2017 figure from the Ellen MacArthur Foundation, which projected that on current trends the oceans could contain more plastic than fish by weight by 2050. Most people absorb the statistic, feel the appropriate spike of dread, and then do nothing differently. The information itself is rarely the problem. The problem is that dread does not convert to habit change, and guilt-driven perfectionism collapses within a month.

This guide is the alternative approach. Reducing plastic is not a moral purity project. It is a set of small behavioural shifts, each one of which would barely show up on its own, but which compound into something meaningful across a year. Nobody becomes zero-waste. Most households can reasonably cut between 30% and 60% of the plastic they currently throw away without sacrificing anything that actually matters to them. That is the productive target, not a spotless bin.

The single honest fact that makes the case

The same Ellen MacArthur Foundation report found that globally, only 14% of plastic packaging is collected for recycling after use. The rest escapes into the environment, goes to landfill, or gets incinerated. Recycling, taken at face value, solves about one-seventh of the problem.

This is why the single most effective thing you can do is not recycle more. It is use less of the packaging in the first place. Reuse beats recycle, every time. A glass jar used a hundred times, a fabric bag used weekly for two years, a refillable bottle used for a decade – these remove the disposal problem from the equation rather than trying to solve it after the fact.

The rest of this guide is the practical version of that principle, in the categories where most household plastic actually lives.

Do one week of noticing before you change anything

Before you swap anything, spend a week paying attention to where plastic enters your home. Not obsessively. Just enough to build a mental map.

Most people discover that the bulk of their household plastic comes from three or four specific places. Food packaging, mainly from the weekly supermarket shop. Cleaning products and toiletries. Takeaway and food delivery containers. The occasional big category like nappies or cat litter.

Knowing which categories are your largest is what makes the next step manageable. There is no sense in obsessing over a single plastic toothbrush a month if the real volume in your bin is coming from grocery shopping. The categories are not all equal.

Keep it simple: for seven days, notice what you throw away and group it roughly. A mental audit is fine. A literal list in your phone is better.

Start with the one category that matters most in your house

Trying to switch everything at once is how almost everyone gives up. Behaviour-change research is consistent: adding one new habit at a time and letting it become automatic before adding the next is roughly twice as likely to stick than trying to overhaul multiple categories simultaneously.

Pick the category your week of noticing identified as largest. For most people that is one of three:

Food shopping. The shift here is buying loose rather than packaged where your supermarket allows it, taking your own bags and containers for the counters that will use them, and finding one or two local refill options for dry goods like pasta, rice, oats, and lentils. Most UK towns now have at least one refill shop. The Ethical Consumer directory lists them; so does a Google search for “refill shop [your town]”.

Cleaning products and toiletries. The refill shift is most developed here. Most major UK supermarkets now stock concentrated cleaning products (Ecover, Method, Smol) where you reuse one bottle and top up with water. Shampoo bars, conditioner bars and solid soaps replace plastic bottles one-for-one. Refillable aluminium deodorants replace plastic roll-ons. None of these require a research project. They just require buying the refill version the next time the current one runs out.

Water and drinks. A single reusable water bottle, used daily for a year, replaces hundreds of single-use bottles. A reusable coffee cup does the same for takeaway coffees. The carbon payback on both typically sits around twenty uses, which is a fortnight for most people.

Pick the category most relevant to your week’s audit. Commit to the swap for a month. Move on only when the first one is automatic.

Use what you already own before you buy new

Plastic containers you already own are not the enemy. The environmental cost of making them has been paid. Throwing them away to buy a “plastic-free” alternative is worse than keeping and reusing them.

A used ice cream tub is a free food-storage container. A passata jar with a good seal is a free spice jar. A shampoo bottle with a pump mechanism is a free refillable soap dispenser if you buy bulk hand soap. The Japanese concept of mottainai – the sense that it is a shame to waste the useful life in something – captures the principle better than most sustainability slogans.

The rule of thumb: only buy a purpose-made reusable when the thing it replaces is actually worn out, when you genuinely do not have a workable substitute, or when the new item will be used so often that the upfront cost pays back quickly. For most households, the reusable items that clearly meet this test are: one good water bottle, one good coffee cup, two or three cloth shopping bags, and a few beeswax food wraps. Everything else, use what you have.

Find one refill option locally, use it for a month

The single most effective habit-forming step is establishing one refill routine you actually maintain. For most households, that means locating a local refill shop – or a refill section at the local supermarket – and using it once for one product category.

The category matters less than the establishment of the routine. Washing-up liquid. Laundry detergent. Olive oil. Pasta. Lentils. Shampoo. Whichever you use most. Buy a bottle or container from the shop, or bring one from home, and do the refill once. Then bring it back next time.

DEFRA research on household waste shows that refill-based buying reduces household packaging waste by a meaningful margin, and that most people who start refilling for one category add others within six to twelve months. The second category is easier than the first. By the third, it is the default rather than the novelty.

Learn the plastic codes, but do not rely on them

The resin identification code on plastic packaging – the number from 1 to 7 inside the triangle of arrows – tells you which type of plastic it is. In theory this tells you what recycles and what does not. In practice, only two of the seven reliably recycle at UK scale.

PET (code 1, drinks bottles, clear food packaging) recycles well. HDPE (code 2, milk bottles, detergent bottles) recycles well. Polypropylene (code 5) is increasingly collected kerbside but recycles less cleanly. The rest – PVC, LDPE, polystyrene, mixed plastics – almost never recycle in practice, according to the 2024 Big Plastic Count survey by Greenpeace UK and Everyday Plastic, which estimated that only around 17% of UK household plastic is actually recycled, with the majority being incinerated.

The practical upshot: when you do have to buy plastic, choose codes 1 or 2 where possible. But recognise that the recycling symbol on most other plastics is the manufacturer’s aspiration, not the council’s capability. For the longer explanation, see our biodegradable, compostable, recyclable guide.

What good looks like after a year

A realistic end state after twelve months of slow, non-dramatic change for most households:

A reusable water bottle, coffee cup, and three or four cloth shopping bags, used consistently. One local refill routine established and maintained – usually cleaning products, sometimes toiletries, occasionally dry food. Solid-bar replacements for a few of the bathroom products that used to come in bottles. A handful of food-shopping habits that cut the weekly plastic – buying loose fruit and veg where available, bringing containers to the butcher or cheese counter, skipping the thin produce bags.

Not zero plastic. Nowhere near it. But reliably 30 to 60% less plastic in the weekly bin, with no ongoing mental effort because the habits have settled into routines. That is the honest, sustainable version of plastic-free living.

FAQs

Biodegradable. Compostable. Recyclable. They sit next to each other on packaging, with similar leaf-green logos and similar implicit promises, and they do not mean the same thing. The words describe three different processes, with different timelines, different conditions, and different outcomes for what actually happens to the item after you throw it away.

Marketing departments rely on that confusion. When most people read “biodegradable” on a plastic bottle, they picture it quietly dissolving into soil. What it usually means, in practice, is that it fragments into microplastics that persist in the environment for decades or centuries. The gap between the promise and the practice is where greenwashing lives, and closing it is the main point of this guide.

None of what follows requires a science degree. It requires five minutes of reading the label instead of the logo.

Biodegradable: the weakest claim

Biodegradable, as a word, means capable of being broken down by microorganisms. In practice it has no legally binding timeline, no test for what the material becomes, and no requirement for the residue to be harmless. Which means it is, on its own, almost meaningless as a consumer signal.

Paper is biodegradable. So is cotton, wool, and most untreated plant fibre. Those biodegrade into the same constituents they came from, within months, in normal conditions.

Then there is “biodegradable plastic.” This is the label that does the most damage. In most cases, it refers to plastic that has been chemically engineered to fragment faster than conventional plastic, or blended with additives that speed that fragmentation. What it becomes as it “biodegrades” is smaller and smaller pieces of plastic -microplastics, then nanoplastics -which do not meaningfully return to nature. They persist, they enter the food chain, and they end up in human blood.

The useful question to ask when you see the word is not “does it break down?” but “what does it break down into?” Paper, plant fibres, and certified compostable materials give a clean answer. Plastic labelled biodegradable usually does not.

Compostable: the precise claim

Compostable is the term that actually means something, because it is tied to a testable standard. In Europe, that standard is EN 13432, published by the European Committee for Standardization in 2000 and adopted by national bodies including the British Standards Institution. In the UK you will often see it as BS EN 13432.

The standard requires four things. The material must disintegrate, meaning fragment to pieces smaller than 2 mm, within 12 weeks in industrial composting conditions. It must fully biodegrade, meaning at least 90% of its organic carbon converts to carbon dioxide within six months, according to the European Bioplastics association. The residue must not harm the compost or the plants grown in it. And it must contain only trace amounts of heavy metals.

Crucially, EN 13432 certifies industrial compostability. Industrial composting runs at around 58°C for several weeks. A home compost heap typically runs at 20 to 30°C, takes much longer, and will not break down most EN 13432-certified materials in any reasonable timeframe. If you want compostable material that also breaks down in a garden compost, look for the separate “OK Compost Home” certification, which tests for 12 months at ambient temperature.

The honest version of the claim is therefore: a certified compostable item will break down completely, in the right facility, without leaving harmful residue. A compostable item in a landfill or your kitchen bin just sits there.

Recyclable: the word that has done the most harm

Recyclable means a material can, in principle, be reprocessed into something new. It does not mean it will be. The gap between those two is the entire problem.

The UK government’s official figures for 2024 show a plastic packaging recycling rate of between 51 and 53.7%, according to DEFRA’s waste statistics, based on data submitted by accredited reprocessors and exporters. That includes plastic exported to other countries for processing, not all of which reaches a reprocessor.

Independent surveys suggest the real-world number for household plastic is considerably lower. The Big Plastic Count 2024, a citizen-science survey of 225,000 UK households run by Greenpeace UK and Everyday Plastic, estimated that only around 17% of UK household plastic waste is actually recycled. Around 58% is incinerated, most of the rest landfilled or exported. The gap between the two figures reflects what counts as “recycled” in official statistics versus what actually becomes new material.

The practical rule is this: of the seven plastic types identified by the resin identification code on packaging, only two recycle reliably at scale. PET (code 1, used for drinks bottles) and HDPE (code 2, used for milk bottles and detergent containers). Polypropylene (code 5) is recyclable in principle and increasingly in UK kerbside schemes, but recovery rates are lower. Polystyrene (code 6), PVC (code 3), and mixed plastics (code 7) almost never recycle in practice. Once you colour a plastic, add a film layer, or combine two types into a composite, the cost of separating them usually exceeds the value of the recovered material.

Black plastic ready-meal trays, crisp packets, toothpaste tubes, squeezable sauce bottles, coffee cup lids -these carry the recycling symbol because they contain recyclable polymer, but the sorting infrastructure does not recover them. The symbol is the manufacturer’s aspiration, not the council’s capability.

The downcycling problem

Even when plastic is recycled, it usually comes out lower-quality than it went in. Contaminants accumulate. Polymer chains shorten. A plastic bottle becomes fibre for a fleece jacket, which then becomes filling for upholstery, which then becomes landfill. The material has been recycled, technically, but the recycling has delayed the landfill trip rather than prevented it.

Glass, metal and paper downcycle far less. Aluminium is the standout: it can be recycled indefinitely with minimal quality loss, and around 75% of all aluminium ever produced is still in circulation. Glass behaves similarly. This is one reason many circular-economy efforts prioritise these materials over recyclable plastic.

The hierarchy that actually works

Put these three words in order of real-world impact and they invert almost entirely from the marketing.

Reuse beats recycling, every time. A glass jar used a hundred times, a metal water bottle, a refillable aluminium deodorant case -these remove the disposal question from the equation rather than trying to solve it after the fact. Reusable formats carry an initial carbon cost from manufacturing, but that cost is amortised across hundreds or thousands of uses rather than one. Any WRAP analysis of consumer packaging consistently shows reuse as the dominant lever.

Compostable is second best, in the narrow case where there is a certified industrial composting route and the material is certified for it. For most UK households, that means looking for the Seedling logo from Din Certco or the TÜV Austria “OK Compost” mark, and checking whether your local authority collects food waste (this is becoming mandatory across England by March 2026 under the Simpler Recycling reforms).

Recyclable is third best, and only within the plastic types and local infrastructure that actually recycle. The recycling symbol alone is not enough.

Biodegradable, without a specific standard attached, should be treated as a marketing term.

How to shop around this

Four practical rules hold up against almost any “eco-friendly” claim.

Ask what it becomes. Paper and certified compostable items become soil. Aluminium, glass and PET become themselves again. Most plastics become something lower-grade. Biodegradable plastics often become microplastics.

Favour reusable over single-use, even when the single-use is labelled eco. The carbon maths almost always works out after ten to twenty uses, and most reusable containers last for thousands.

Read the small print on “compostable” claims. Industrial-compostable only (which is most of them) is useful only if you have the collection route. Home-compostable items are genuinely compostable in an ordinary garden heap.

Distrust “biodegradable plastic” as a category. If it matters to you that the item returns to nature rather than fragmenting into pollution, choose paper, cardboard, certified compostable plant-based fibres, or a reusable alternative.
