REBRI Resource Recovery Timber: Processing into Mulch and Chip (PDF)

This guide provides good practice advice to maximise recovery rates for waste timber from construction and demolition (C&D) projects by improving shredding and screening processes. The guidelines cover the processing of pre-sorted waste timber into chip or mulch product and the stockpiling of the processed products.

The aim is to assist the operators of shredding and screening systems to adopt practices that:

• maximise operational efficiency and the amount of waste timber processed
• minimise contamination or damage of the mulch or chip product
• minimise the inappropriate burning or processing of treated timber
• avoid or minimise environmental and nuisance effects from processing.

This guideline covers:

• finding good markets for waste timber
• on-site versus centralised processing
• setting up a processing facility or mobile operation
• operating a timber-processing plant
• storing chip and mulch products
• environmental, health and safety hurdles
• resources and contacts
• other guidelines in this series.
