Recycling contamination is mostly a design problem rather than a motivation one, and it is fixed at the point where things are thrown away.
Sorting Happens at the Bin
If separating requires walking to another room, it will not happen consistently.
Whatever your local authority collects should have a container in the kitchen, at the point where waste is generated. Anything requiring a journey ends up in the general bin.
That is not laziness; it is how everybody behaves.
Size Them by Volume Generated
- Recycling volume is usually larger than general waste
- Most kitchens have this backwards
- Food waste needs a small caddy emptied often, not a large one
- Glass needs somewhere it will not be knocked
- A small bin filled daily beats a large one emptied weekly
Ranges carrying several bin sizes and step bins for small spaces, of the kind at bino.us.org, matter because a bathroom, a kitchen and a home office generate very different volumes.
Check What Your Council Actually Takes
The step that removes most contamination. Rules vary enormously between areas, and assumptions are usually wrong.
Common errors: greasy pizza boxes, black plastic trays, crisp packets, coffee cups, and anything with food residue. Contaminated loads can be rejected entirely, which wastes the whole batch.
Rinse containers, and print the local list inside a cupboard door where people can read it.
Batteries Never Go in a Bin
Worth stating separately because it is not widely known. Lithium batteries cause fires in bin lorries and at waste facilities, and those fires are frequent, dangerous and expensive.
Batteries, power banks, vapes and any device with a built-in cell go to a designated collection point. Most supermarkets have one.
Other Things That Do Not Belong
Paint, solvents, garden chemicals, motor oil and old medicines all go to household hazardous waste or a pharmacy rather than a household bin or a drain.
Aerosols, even empty, should follow local guidance since they can explode when compacted.
Odour Is a Liner and Frequency Problem
Food waste caddies smell because they are emptied weekly rather than daily.
Emptying the caddy into the outside bin every day or two, and rinsing it, removes the problem. A lid helps and does not substitute.
Step Bins and Small Spaces
A foot pedal means no touching a lid with dirty hands, which matters in a kitchen.
Line What Needs Lining
Dry recycling generally does not, which saves bags.
Empty Before It Is Full
Overfilled bins are where sorting stops.
