Setting Up a Zero-Waste Kitchen

The packaging problem

Supermarkets in Poland — like those across the EU — are subject to packaging regulations under Directive 94/62/EC on packaging and packaging waste, but the volume of plastic and multilayer packaging in everyday grocery shopping remains high. A typical week of groceries for a household of two can generate over a kilogram of packaging waste.

The most direct way to reduce this is to shift purchasing to products with minimal or no packaging. Loose vegetables, bulk cereals, and refillable containers eliminate the wrapper before it enters the home.

Buying loose produce

Most Polish city markets (targi) and a growing number of supermarkets offer unpackaged fruit and vegetables. Biedronka, Lidl, and Kaufland have introduced sections with loose produce in larger stores. The Jarmark on Plac Defilad in Warsaw, for example, operates year-round with a wide variety of unpackaged seasonal produce.

Cloth produce bags — available from zero-waste shops or homemade from old fabric — replace the thin plastic bags provided at the scales.

Glass jars and reusable containers

Glass jars can replace a wide range of plastic packaging in dry-goods storage. Pasta, rice, lentils, nuts, and flour stored in sealed glass jars keep longer than in open packets and make pantry inventory visible at a glance. Second-hand stores (second-handy) and markets often sell glass jars at low cost.

Food waste and composting

Polish law (Ustawa z dnia 13 września 1996 r. o utrzymaniu czystości i porządku w gminach, amended in 2019 and 2021) requires municipalities to provide separate collection of bio-waste. Brown bins are now standard in residential areas of most Polish cities. However, the volume of food waste that passes through them is still lower than in Western European countries.

Meal planning

The most effective way to reduce food waste is to reduce the amount of food purchased beyond immediate needs. A basic weekly meal plan — even an informal list — reduces impulse buying and the likelihood of ingredients spoiling before use. Recipes that use whole vegetables (including peels and stalks) further reduce what goes to bio-waste.

Home composting

For households with a garden, an outdoor compost bin processes vegetable peelings, eggshells, coffee grounds, paper, and garden cuttings into usable compost within several months. Many Polish municipalities, including Warsaw and Kraków, offer subsidised compost bins for residents — check the local gmina website for current programmes.

Apartments and smaller spaces can use a vermicomposting bin (with worms). The process handles kitchen scraps including fruit and vegetable peelings, tea bags, and coffee grounds. It produces a high-quality liquid fertiliser alongside solid vermicompost.

Replacing single-use items

Several items in a standard kitchen are typically single-use but have durable alternatives:

• Kitchen paper towels — replaced by cut-up old cotton t-shirts or dedicated cloth wipes, washed with regular laundry
• Cling film — replaced by beeswax wraps (available in Polish eco-shops and online) or silicone stretch lids
• Plastic bags for freezing — replaced by glass containers or silicone bags rated for freezing
• Disposable coffee cups — many coffee shops in Poland apply a small discount for customers who bring their own cup
• Plastic straws — banned from single-use plastics sale in Poland since 2021 under EU Directive 2019/904

Cleaning products

Conventional cleaning products come in plastic bottles with limited recyclability due to contamination. Concentrated refillable versions — sold in zero-waste shops and some pharmacies (drogerie) — reduce plastic consumption significantly. Basic alternatives like baking soda (soda oczyszczona) and white vinegar (ocet) cover many cleaning tasks at lower cost and with no packaging beyond a paper bag or glass bottle.

What to do with packaging that can't be avoided

Some packaging is unavoidable. Poland's sorting bins are colour-coded:

1. Yellow bin — plastics, metals, multilayer packaging (Tetra Pak)
2. Blue bin — paper and cardboard
3. Green bin — glass (coloured and clear in separate bins where provided)
4. Brown bin — bio-waste
5. Grey or black bin — mixed residual (non-recyclable)

Items that cannot go into household bins — batteries, electronics, medications, large appliances — have separate collection points (punkty selektywnej zbiórki odpadów komunalnych, PSZOK) in every municipality. Their locations are published by the local commune.
