WDU Composting Technologies

Delivering innovative, energy efficient and cost effective technology for on-site processing of organic waste.

OSCA - On-Site Composting Apparatus

OSCA is an automated, aerobic composting technology developed by WDU Sustainability in Queensland, Australia. Using minimal energy, OSCA processes organic waste streams including food waste (food preparation waste, plate scrapings, bones, seafood, etc.), agricultural waste, compostable packaging, paper and cardboard, manure, and green waste. OSCA can produce a high quality, safe and immediately usable compost within 10 - 14 days.

OSCA is a continuous feed system - waste is loaded in one end and finished compost ejected from the other. OSCA is silent in operation and the specially designed bio-filter makes it odourless. The unit is very easy to use and maintain.
