Where do Window and greenhouse glass go?

Flat glass has a different composition from container glass and often a coating — low-emissivity films, laminate interlayers, toughening — none of which belongs in a bottle melt. It is recyclable through flat glass processors, and household waste centres usually have a skip for it. Toughened glass shatters into small cubes and laminated glass tears rather than breaking, and both are heavy and awkward, so transport them flat and edge-protected. Glaziers replacing a unit normally take the old one away, which is easier than doing it yourself. Local sites differ on quantities of flat glass and on charges, so check before loading the car.

How to prepare it

1. Tape the edges and carry sheets vertically, with gloves.
2. Ask the glazier to take the old glass; most will.

What not to do

• Never put window glass in a bottle bank; it is a different material and it contaminates the batch.

Kerbside collection rules genuinely vary by council and county, and local rules always win over general guidance. The reasoning above is what transfers — if your service differs, it will usually be for a reason described here.

Other things that go to household waste recycling centre

• Leftover wet paint Household waste centre or a community paint reuse scheme. Liquid paint is not accepted in any household bin.
• Car batteries (lead-acid) Garage, scrap yard or household waste centre. Lead-acid is the most successfully recycled consumer product there is.
• Used motor oil Household waste centre oil bank, or a garage that accepts it. One container of it contaminates an enormous volume of water.
• Small electricals (kettles, toasters, hair dryers) Electrical waste. Household waste centre, a shop take-back point, or a kerbside small-electricals sack if your council runs one.
• Pyrex and heat-resistant glassware Never the glass bin. Ovenware is formulated not to melt like bottle glass, and one fragment can ruin a whole batch.
• Televisions and monitors WEEE recycling. Old CRT sets contain several kilograms of leaded glass.
• CFL energy-saving bulbs Household waste centre or a shop take-back point. They contain mercury and must not be binned.
• LED bulbs Small electricals recycling. No mercury, but they are electronics, not glass.
• Drinking glasses and wine glasses Not the glass bin. Tableware glass has a different composition from bottle glass.
• Smoke alarms Household waste centre or manufacturer return. Ionisation alarms contain a tiny sealed radioactive source.
• Crockery, mugs and ceramics Not glass and not recyclable at the kerb. Donate what is whole; broken pieces go to the household waste centre or general waste.
• Fluorescent tubes Household waste centre, intact. Mercury inside, and a tube that breaks in transit is a spill.
• Camping gas canisters and butane cartridges Household waste centre, as gas cylinders — not the metal skip and never a bin, whether or not they feel empty.
• Fire extinguishers Household waste centre or a fire equipment company. It is pressurised until a professional has discharged it.
