Innovating the way to a secure and sustainable supply of sand for construction.
Talk to us
Innovative crushing and air screening technology is at the heart of our sand engineering plants. Originally developed because of a ban on dredging in Japan, it provides a better way to obtain sand for use in concrete.
There are now over 300 plants throughout Asia. We are committed to supporting the transition to sustainable concrete for the long-term benefit of the construction industry and our planet.
New Zealand has a history of developing world leading technologies for fine aggregate production. In the 1970s the Barmac crusher was invented by New Zealanders Jim MacDonald and Brian Bartley. Barmacs are now commonplace in quarries around the world.
Kayasand’s founder, Andi Lusty, was Managing Director of the company and supplied Barmac crushers globally for 30 years. In the early 2000s he encountered the revolutionary new Kemco V7 crushing technology developed by their chief engineer, Dr Kaya.
Seeing the growing need for an alternative to natural sand and inspired by Kemco’s technology, he retired from selling Barmacs. He founded a new company to sell the Kemco technology and named it Kayasand, after the technology’s inventor.
In 2016 Kayasand installed and commissioned the first V7-60 plant outside of Asia in Holcim’s Albion Park Quarry. Holcim sell premium manufactured sand from the Kayasand plant to concrete manufacturers in the Sydney area.
In 2023 Kayasand received a $3.5 million investment from New Zealand Green Investment Finance to reduce carbon emissions from concrete. With this cash injection they opened the first V7 high-technology demonstration plant in New Zealand showcasing how the innovative crushing and screening process engineers sand of such high quality it reduces carbon emissions in concrete by 20%.
