Calling all gin drinkers
Do you have a taste for gin in a blue bottle? If so, Silica will pay $1 for empty blue bottles.
What are you waiting for? Cheers!

Using crushed glass
Crushing glass reduces stockpiles and creates a product that has many uses, particularly for New Zealand's local authorities.
We are now producing a 5 millimetre chip, which is excellent as a decorative cover for driveways
Silica Glass Crushers are now crushing glass in the following sizes:
- 1 millimetre down to sand
- 1.5 millimetre down to 1 millimetre
- 5 millimetres down to sand
The 1 millimetre and 1.5 millimetre products are now being used by sandblasters and it's available at $7.00 +G.S.T. per 25 KG bag, ex plant.
We are now producing a 5 millimetre chip, which is excellent as a decorative cover for driveways.
The many uses for crushed glass include:
- Leachate drains
- Sub-base in wet roading conditions
- Garden mulch
- Golf course bunkers
- Utilised in concrete
The crushed glass is reduced in a single pass to 5mm pebbles. The edges are smoothed, making it safe for many outdoor and public access uses.
Re-use or recycle -
crushed glass is safe and versatile.
Home recycling of glass means around a 5% growth in glass recovery year-on-year. New uses need to be found for it.
Transit New Zealand says: "Waste glass that is crushed and screened can be used as a portion of fine aggregate in asphalt paving mixes. Satisfactory performance has been obtained from hot mix asphalt pavements incorporating 10 to 15 percent crushed glass in wearing surface mixes. ...higher blends, incorporating perhaps up to 25 percent, could potentially be used in base or binder course mixes."
Transit quotes a report on its web site that says the City of New York's Department of Transportation used approximately 225,000 metric tons of glass to resurface streets between 1990 and 1995.
They're trialling different crushing methods for base course in Nelson and Palmerston North. This use for glass means there's no need to sort it by colour for recycling.
The New Zealand Turf Institute is working with the Glass Forum to assess glass as a golf course base material and as a mulch in vineyards.
Silaca's portable glass crusher is designed to go where the glass is needed, to avoid big stockpiles being served by big trucks with big loads of broken bottles trundling around the roads.
