What is changing?

We’re a family-owned business based in Forbes, and since 2019 we’ve been transforming organic material into compost at our site north-east of Forbes. We’re proposing to expand the facility to process up to 90,000 tonnes of organic material per year, incorporating anaerobic digestion, GORE® covered composting and additional environmental controls. The proposal would increase organics recovery, produce compost and generate renewable biogas.

What is proposed?

Anaerobic digestion system: a sealed process that breaks down food organics without oxygen and produces renewable biogas

Combined heat and power (CHP) system: uses renewable biogas produced through anaerobic digestion to generate electricity and useful heat for the facility

New enclosed processing building: for receiving and sorting food and garden organics

GORE® covered composting bays: a specialised covered composting system that helps control airflow, moisture and temperature, while improving odour containment and reducing emissions to the surrounding environment

Odour, leachate and digestate management: additional systems to capture and treat odour and collect and manage leachate (liquid that drains from organic material) and digestate.

Biogas upgrading equipment: to upgrade surplus biogas to biomethane for potential supply to the local gas network, subject to final design, network operator requirements and relevant approvals.

How the process works

01
Loads arrive and are weighed and inspected
02
Non-organic contaminants such as plastic are removed during sorting
03
Food organics go to the sealed anaerobic digestion system. Other organics go to GORE® covered composting
04
Biogas is used in the CHP system or upgraded for the gas network. Covered composting controls airflow and temperature. Digestate is treated and may be beneficially reused where it meets applicable requirements
05
Compost matures, is screened and is returned to productive use on farms and soils
