Bulk buying and refill shops: cut packaging and cost

Refill and bulk shopping isn't a niche lifestyle choice — it's a practical habit that cuts the plastic and cardboard leaving your home each week, reduces the amount you throw away, and can save money on the things you buy regularly anyway.

What bulk and refill actually means

The terms are sometimes used interchangeably, but they cover two slightly different things:

• Bulk dry goods: loose staples — rice, oats, pasta, lentils, nuts, dried fruit, spices, flour — stored in bins or hoppers. You fill your own bag or container and pay by weight. These are common in health food shops, some supermarkets (availability varies hugely by country and city), and dedicated zero-waste shops.
• Refill stations: large dispensers of liquid products — washing-up liquid, laundry detergent, hand soap, shampoo, conditioner, cooking oils, vinegar. You bring a clean bottle, fill it up, and pay by volume or weight. Dedicated refill shops and some zero-waste grocers carry these alongside dry goods.

Availability varies a lot. In some cities, refill shops are easy to find; in others, you may only have access to a supermarket bulk aisle or a mail-order zero-waste service. Work with what's near you.

Why it helps

• Less packaging waste. Pre-packaged goods come with plastic bags, cardboard boxes, plastic tubs and films — often multi-layer, hard to recycle. Loose goods need none of that if you bring your own container.
• Buy only what you need. Need 200 g of pine nuts? Buy exactly that. No over-buying, no half-used bags going stale at the back of the cupboard.
• Often cheaper per unit. You're not paying for packaging, labelling or a brand premium. Staples like oats, rice and lentils can be noticeably cheaper per kilogram loose than branded pre-packaged versions.
• Try before you commit. A small scoop of an unfamiliar spice or grain costs very little, so you can experiment without waste.

What's worth buying loose

The best candidates are shelf-stable, high-turnover items you buy regularly:

• Grains and cereals: rice (white and brown), oats, millet, barley, rye flakes, cornmeal
• Pasta and noodles
• Pulses: dried lentils, chickpeas, black beans, kidney beans, split peas
• Nuts and seeds: almonds, walnuts, sunflower seeds, pumpkin seeds, sesame seeds
• Dried fruit: raisins, dates, apricots — in quantities you'll use within a few months
• Spices and herbs: a major win — pre-packaged spices are very expensive per gram; loose spices are often a fraction of the cost
• Flour, sugar, salt
• Cleaning and household liquids: washing-up liquid, laundry detergent, multi-surface cleaner — where refill stations are available
• Toiletries: shampoo, conditioner, body wash — again, where stations are available
• Cooking oils and vinegar at some specialist shops

What to avoid buying in bulk

Bulk buying is only sustainable if you actually use what you buy. Some things are better bought in regular quantities:

• Perishables you can't use up in time — fresh produce, most dairy, meat. If it goes off before you finish it, the bulk "saving" is wiped out by waste.
• Foods you've never tried — taste a small amount first before committing to a large quantity.
• Anything with a short shelf life once opened — some nuts and seeds, especially those high in unsaturated oils, go rancid relatively quickly. Only buy what you'll use within the stated period.
• Strongly scented items that could taint other foods if stored together — spices especially should be sealed well.

Your first refill trip

1. Find your nearest option. Search for "zero waste shop", "refill shop" or "bulk food" near you. Some supermarkets also have a bulk or loose section — worth checking before making a special trip.
2. Gather containers before you go. Clean glass jars (jam jars are ideal), old plastic tubs, cloth bags for dry goods, or empty bottles for liquids. They don't need to be fancy — whatever is clean and sealable.
3. Tare your containers. At most refill shops, you weigh the empty container at the till (or at a scale in-store) and write the tare weight on it. You'll only pay for the contents, not the container. Staff will help if it's your first time — just ask.
4. Start with two or three staples you know you use every week — oats, rice, a pulse, a cleaning liquid. Don't try to overhaul your whole shop at once.
5. Fill your containers. Use the scoops provided and don't overfill — leave room for lids to close properly. Keep different products in separate containers.
6. Pay by weight or volume. Bring the filled containers to the till. The tare weight is subtracted, and you pay only for the contents. Most shops accept card.
7. Label when you get home. Write the contents and date on a piece of tape. This sounds trivial, but after a month your jars of "pale grain" become a guessing game.

Storing bulk food at home

Good storage keeps food fresh longer and keeps pests out — which is how you actually get the savings bulk buying promises.

• Airtight containers are essential. Glass jars with rubber-sealed lids, clip-top tins, and food-grade plastic tubs with tight-fitting lids all work well. Avoid loose lids.
• Label everything with the contents and the date you bought it. Rotate stock — put new food at the back and move older stock to the front to use first.
• Store in a cool, dark, dry place. A kitchen cupboard away from the oven or hob is ideal. Heat and moisture are the enemies of stored food.
• Nuts and seeds with a high oil content (walnuts, flaxseed, hemp seeds) keep longest in the fridge or freezer — they can go rancid at room temperature after a few months.
• Pest-proofing: airtight containers prevent most problems. A traditional trick for flour and grains is to place a dried bay leaf inside the container — it deters grain weevils without affecting taste.
• Spices lose flavour rather than go off — buy in smaller quantities more often, and keep them away from light and heat.

Online and zero-waste delivery options

If you don't have a refill shop nearby, several online retailers ship loose dried goods in minimal or home-compostable packaging. Look for:

• Shops that use paper bags, cardboard boxes, or compostable pouches rather than plastic
• Services that offer return-and-refill schemes for containers
• Buying clubs or community orders, where a group of neighbours orders together to reduce delivery emissions per household

Online bulk isn't perfect — there's still delivery packaging and transport — but it can be a significant step down from weekly single-serve plastics. See also our guide to reducing plastic use for more ideas beyond food.

Bulk and refill checklist

• Identify your nearest bulk or refill shop (or a supermarket bulk aisle).
• Collect 3–5 clean jars or containers before your first visit.
• Pick 2–3 staples you always have in your cupboard to buy loose first.
• Tare containers at the shop so you only pay for the food.
• Label everything with name and date when you get home.
• Store in airtight containers in a cool, dark cupboard.
• Rotate stock — oldest goes to the front.
• Only buy quantities you'll genuinely use before they go stale.
