Bulky Waste vs. Household Waste: Züri-Sack Guide & Rules

Standing at the kerb with a blue bag in one hand and a broken lamp in the other is one of the most common moments of disposal confusion in Zurich. The Züri-Sack and Sperrgut are two completely separate systems with separate rules, separate pricing, and separate collection days, and mixing them up is the fastest way to have your rubbish left uncollected.

This guide draws a clear line between the two: what actually belongs in the Züri-Sack, what belongs in the bulky waste stream instead, and the current bag prices and sizes. If you need bulky waste disposal in Zurich, it also explains what happens when items are disposed of incorrectly and how to avoid unnecessary fines or rejected collections.

What Is the Züri-Sack?

The Züri-Sack is the official, mandatory refuse bag for Hauskehricht, ordinary household waste, in the City of Zurich. It's been blue since 2023, when the city redesigned it and reduced the built-in fee by 25 percent. Only rubbish set out in a genuine Züri-Sack is collected; loose bags or unofficial bin liners are left behind.

Züri-Sack Sizes and Prices in 2026

Each bag size carries a fixed city fee, which covers collection and processing at the Hagenholz waste treatment plant. The retail price you pay at the till is higher, since it also includes production, distribution, and the retailer's own margin, which is why prices vary from shop to shop.

Only the fee portion is fixed by the city; the shelf price is set by each retailer. Reported differences have reached over CHF 14 per roll for 110-litre bags between the cheapest and most expensive sellers, with discounters like Aldi and Lidl typically among the lowest-priced options, and convenience stores, pharmacies, and petrol stations often the most expensive.

What Belongs in the Züri-Sack

The Züri-Sack is for everyday, non-recyclable household refuse that fits inside the bag and lets it close properly:

•      General food packaging that isn't separately recyclable

•      Nappies and hygiene products

•      Broken small household items, such as cutlery, small plastic items, or ceramics that don't qualify as Grubengut in bulk

•      Vacuum cleaner dust bags, cleaning residue, and similar non-recyclable waste

•      Any general rubbish that isn't covered by a separate collection stream for paper, bio-waste, glass, or metal

What Does NOT Belong in the Züri-Sack

Key Takeaway

A simple rule of thumb: if it fits inside a Züri-Sack and the bag closes flat, it's household waste. If it's oversized, heavy, electronic, made of glass or metal, or hazardous, it belongs in a different stream entirely, not the blue bag.

What Happens If You Mix Them Up

Rubbish set out in anything other than an official Züri-Sack, including oversized items stuffed into or piled beside one, is simply left uncollected. Repeated or deliberate incorrect disposal on public land can be treated as illegal dumping, which carries a fine in the same range as other Sperrgut violations, roughly CHF 200 to 500.

The Grey Zone: Small Bulky-Adjacent Items

A few items sit right on the boundary. A single broken chair leg or a flattened cardboard box goes in general waste or paper collection, respectively, not Sperrgut. A whole broken chair, even a small one, needs a Sperrgutmarke. Kitchen items like small appliances or cookware in bulk, following a kitchen renovation for instance, usually don't belong in the Züri-Sack either and need their own disposal route.

The Faster Way to Handle a Mixed Load

A single bag of household rubbish is easy to sort correctly with this list. A full apartment clearance or a basement full of years of mixed items rarely separates neatly into Züri-Sack, Sperrgut, Grubengut, and e-waste on its own. It's usually all of it at once.

Conclusion

The Züri-Sack and Sperrgut are separate systems, and the boundary is simpler than it looks: if it fits in the bag and the bag closes, it's household waste; if it's oversized, heavy, electronic, or hazardous, it needs a different route entirely. Getting this wrong means a missed collection at best and a fine at worst. For a single bag, this guide is all you need.

Frequently Asked Questions

What size Züri-Sack should I buy?

It depends on your household size: 10 or 17 litres suits a single person with light weekly waste, 35 litres fits most smaller households, and 60 or 110 litres suits larger households or shared properties.

Why do Züri-Sack prices vary between shops?

Only the city's fee portion is fixed, roughly CHF 0.37 to CHF 1.30 depending on size. The shelf price also includes production, distribution, and the retailer's margin, which can differ by more than CHF 14 per roll for the largest bags.

Can I put a broken chair in the Züri-Sack?

No. Even a small broken chair counts as Sperrgut and needs a Sperrgutmarke or a separate collection route, not the household refuse bag.

What happens if I use the wrong bag?

ERZ leaves it uncollected. Repeated or deliberate incorrect disposal on public land can be treated as illegal dumping, with a fine of roughly CHF 200 to 500.

Do electronics or batteries go in the Züri-Sack?

No. Electronics and batteries need to go through certified SENS/Swico e-waste recycling, often free at the retailer where they were purchased, never in general household refuse.
