The team has a comprehensive network of contacts on a national and international level. We are familiar and have good working relations with a number of Australian and international composting facilities in USA, Latin America, 6 European countries and South East Asia, covering the full range of technologies available in organic waste processing. We also have information exchange and working relations with private and academic research organisations. We have developed successful composting strategies for wool scouring and anaerobically digested industrial sludges, as well as domestic organic waste, green waste, potato waste, fish waste and a range of other industrial, agricultural and commercial organic wastes. Our engineering designs take into consideration optimisation of composting rates, odour control, nutrient recovery, EPA approval criteria, pathogen and plant disease destruction, and a quality end product.

We have productive contacts in Asia, particularly, Java, Bali, India, Malaysia and China and have developed proposals for consulting, engineering and technology transfer in India and Indonesia. We are also represented on the National Committee of Standards Australia for the development of the National compost standard and have contributed to biosolids reuse guidelines and National and State organic waste management strategies.



FABCOM® Hybrid Composting System

This system has been designed and developed for large scale processing of high volumes of organic waste where odour emission and leachate generation are of concern. This system is flexible in capacity and most economical for large scale centralised (1,000 – 150,000 m3 pa) processing.

FABCOM® Bioremediation System

This system has been designed and developed for large scale bioremediation of organic chemical contaminated materials. The system offers a unique design, incorporating a specially designed removable cover, which prevents odours and vapour emissions, eliminates weather effects and allows controlled process conditions, and leachate recirculation via a leachate pond and irrigation system, which provides moisture to the system and acts to solubilise the contaminants to improve the remediation rate. This system is also flexible in capacity.


This is an on-site aerobic/anaerobic, in-vessel composting system for the rapid stabilization of food waste, septic wastes, biosolids and paper/cardboard, which the BIOBOX converts into valuable, odourless soil amendments within a two week cycle. The BIOBOX can also be used as a mobile reactor for the rapid bioremediation of hydrocarbon and pesticide contaminated soils.


METALOK is a specially formulated compound that is very effective in reducing heavy metal contamination in soils, water and solid waste by the integration of several active metal immobilisation mechanisms. METALOK can be applied to contaminated soils to achieve TCLP test compliance; composting of organic wastes, such biosolids or municipal waste, which may cause metal contamination; and the treatment of metal containing waste waters such as metal plating and photolabs.


Utilisation of the GLASS CRUSHER ensures the cost effective recycling of glass, and saves valuable landfill space. The GLASS CRUSHER reduces the volume of glass by up to 80%, improving the transportation of glass five fold and thus significantly reducing transport costs. In addition, crushing of the glass into fine cullet eliminates the risk of glass related accidental or inflicted injury. The glass crusher is an essential on–site recycling tool worth incorporating into the waste management strategy, reducing volume and promoting occupational and environmental health.


The recyclables compactor is a fully automated on site compacting system which hydraulically compacts cardboard, paper, sawdust, plastics and aluminium waste, reducing volume by 95%. Compaction of plastics and aluminium waste produces stackable briquettes for low cost transport. Compaction of cardboard and paper produces fire or barbeque briquettes suitable for cooking and heating.


This technology is designed to desalinate water, for use in irrigation, and the removal and recovery of heavy metals from waste waters. The technology can be placed in-line for continuous extraction of salts and metals from waste and storm water streams and drains.
