Rarotonga’s landfull has been waiting for years for a suitable glass crusher. Now, Rarotonga’s landfill will finally be cleared of glass bottles.


This comes after the team at the Resource Recovery Centre finally received an industrial glass crusher this week.

According to Infrastructure Cook Islands, staff and contractors were busy this week brainstorming and manoeuvring the industrial glass crusher out of its shipping container and into the Resource Recovery Centre shed.

The ministry says the Rarotonga landfill receives 916 tonnes of glass bottles per year which have been used for cover, so still has been very important to separate at source.

Now, they will divert all the glass (separated at source) from landfill (45 per cent in total weight to landfill) and produce a usable sand substitute.

The contractor Timberland Limited, the on-island agent for product supplier Expleco Limited, the company who supplied the crusher will be training the staff on operation and maintenance of the crusher.

Earlier this year upon an agreement with the Embassy of Japan, a project was funded by the Government of Japan through a grant assistance of $178,391.

The grant was for the sealing of the drop-off yard/working area with concrete and provide drainage and septic catchment and the installation of an industrial-sized glass crusher to reduce landfill waste, allowing for a more well-organised working environment.

Hilary Boyes, Infrastructure Cook Islands’ first dedicated waste programme coordinator, had earlier said the machine would crush glass into the particle size of sand, and then the glass could be substituted for sand in concreting – leaving the sand where it belongs.
