Organics co-processing is where multiple residual organic materials are combined and processed together to achieve a final product of higher value than if it was processed alone.

Technologies suitable for co-processing include vermicomposting, black soldier fly composting, composting, anaerobic digestion and pyrolysis.

Products are usually soil amendments and/or energy that a farmer can sell or reutilise on farm, adding a revenue stream or reducing input costs in their operation.

This fact sheet focuses on:

1. Composting producing compost; and

2. Wet anaerobic digestion producing biogas and digestate.

It outlines key considerations for organics co-processing, available technologies, feedstock value and suitability, and tips to get started.
