Key Services New Zealand

The PTS laboratory in Kawerau, New Zealand has a 25-year history of testing wood-based and agricultural products for a variety of uses, including biofuels. It operates 365 days a year and is open to enquiries from across the primary industry for the services it provides.

PTS currently tests for:

  • Moisture content (dry matter)
  • (Particle) size (classification)
  • Ash content
  • Bulk and basic density
  • Calorific value

Tests are regularly carried out on woodchips, wood residues and hog fuel, wood discs (from logs), increment cores (from standing trees), silage and grass.

The same tests apply to other biofuels, such as briquettes and pellets, additional agricultural feedstocks such as hay and a broad range of horticultural products such as blueberries, avocadoes and kiwifruit.

PTS also runs a Quality Management System (QMS) for major woodchip providers and users. It receives samples from across New Zealand and also carries out sampling services for clients. As an independent laboratory, PTS is ideally placed to perform testing for verification and quality control purposes e.g., for new and existing biofuel producers.

Further test methods are being developed to allow a more complete service in the areas of diagnostic testing. Please get in touch with any queries.
