Sell or recycle glass waste: what businesses need to know
Glass is heavy and low in value, so small volumes are rarely bought. The gain for most businesses is a lower waste bill, although large, clean, colour separated tonnages do have a market.
This guide is for businesses. If you are a householder, use your council's recycling service or your local recycling centre instead.
What is waste glass worth?
Recycled glass, called cullet, is sold per tonne at a low price compared with metal or cardboard. Because it is heavy, haulage takes a large share of its value.
What decides its value:
- Colour. Glass sorted into clear, amber and green can be melted into new bottles, which is the best paid use.
- Contamination. Ceramics, stones and heat resistant glass ruin a load for remelting.
- End use. Mixed glass often becomes aggregate, which pays the least.
- Distance. The closer you are to a processor, the more of the value you keep.
Even where no one pays for it, separating glass removes a heavy material from your general waste, which is usually charged by weight.
For current market figures, see our glass recycling prices page, which is updated every month.
Types of waste glass
| Type | What it is | Notes |
|---|---|---|
| Clear | Clear bottles and jars, also called flint | The best paid colour |
| Amber | Brown bottles | Mid range |
| Green | Green bottles | Often the lowest of the three colours |
| Mixed colour | Unsorted bottles and jars | Lower, as it must be sorted or used as aggregate |
| Flat glass | Window and plate glass | A separate stream. Never mix it with bottles |
| Laminated and toughened | Windscreens and safety glass | Specialist recyclers only |
How to prepare glass for collection
- Keep bottles and jars separate from window glass. They are different materials.
- Keep out ceramics, drinking glasses, cookware, mirrors and light bulbs.
- Empty bottles and jars. They do not need washing, and labels can stay on.
- Sort by colour only if your buyer pays for it and you have the volume.
- Use lidded bins and watch the weight, as full glass bins are heavy to move.
Your legal duties for glass waste
- Duty of care. Your business must store its waste safely and hand it only to someone authorised to take it. See the official guidance.
- Registered carrier. Whoever collects your material must be a registered waste carrier. Check the public register before the first collection.
- Waste transfer note. Complete one for every load, or a season ticket for regular collections, and keep it for two years.
- Carrying it yourself. If you regularly transport your own business waste you must register as a waste carrier. In England this is free when you only carry waste your own business produced, unless it is construction or demolition waste.
- Separation at work. In England, workplaces must keep dry recyclables, food waste and non recyclable waste apart. The rules began on 31 March 2025, and firms with fewer than 10 full time equivalent employees have until 31 March 2027. Read the rules.
- Digital waste tracking. Since 1 October 2026, permitted sites that receive waste in England and Wales must record each load in the government's digital service. Carriers and dealers are due to follow in a later phase, so keep your transfer notes.
Rules differ slightly in Scotland, Wales and Northern Ireland. This is a plain English summary, not legal advice.
How to find a buyer or carrier for glass
- Register your business on The Green Alchemist.
- Create a selling listing with the grade, quantity, location and a clear photo of your glass.
- Browse the directory of waste processors to find buyers and carriers who handle glass, and contact them directly.
- Compare offers on price, collection and payment terms, and check each buyer's registration.
- Agree the collection, complete the waste transfer note and get paid by bank transfer.
Frequently asked questions
Will anyone pay for my glass?
For small volumes, usually not. Large, clean tonnages that are sorted by colour can earn a price. For most businesses the saving comes from lower general waste charges.
Can window glass go in with bottles?
No. Window glass melts at a different temperature and contaminates bottle glass. Keep it as a separate stream.
Do bottles need to be washed?
No. They only need to be empty. Labels and small amounts of residue are removed during processing.
Does my business have to separate glass?
In England, yes. Glass is one of the dry recyclable materials that workplaces must keep apart from general waste.
