Silaca Glass Crushers came about when owner and CEO Barry Lucinsky was asked to come up with a possible end use for stock-piled glass. The proposal - to incorporate
 crush glass into roading aggregate - was accepted and a trial programme commenced.

Silaca Glass Crushers provided a mobile crusher travelling from North Cape to Bluff, proving that not only was adding crushed glass feasible, it was competitive.Since then Silaca has established a glass recycling operation at the Otaki and Waikanae Transfer Depots which operates 7 days a week.

"It's busy," Barry Lucinsky says. "We've got three people on staff who operate the plant, carry out maintenance, run the website, handle the marketing, host visiting groups and travel around doing presentations. Long hours, diligence and tenacity are the key. Before we got involved all waste glass here was going to the landfill - around 600 tonnes a year."

Since Silaca's been in operation the volume of glass received has increased to over 1000 tonnes a year, as result of public awareness. Over the summer months, daily volumes exceed 4 tonnes a day, or around 12,000 bottles.

Silaca has developed processes where crushed glass is used in pavers, decorative beads, anti-skid treatments, filter media and sand-blasters.

Silaca has exported crushers to Darwin, Australia, and to the Cook Islands, with two other crushers being established in the South Island.
