Product Overview

Summary: This Bark Processing and Disposal SOP provides a clear, step-by-step method for safely handling, processing, storing and disposing of bark generated in forestry, landscaping, sawmilling and horticultural operations. It helps Australian businesses control fire risk, dust, manual handling injuries and environmental non-compliance while turning a waste stream into a managed, traceable process.

Bark generated from tree felling, debarking, milling, landscaping and horticultural activities can pose significant safety, fire and environmental risks if it is not managed systematically. Uncontrolled bark piles can self-heat and ignite, attract vermin, generate airborne dust and spores, and create unstable walking and working surfaces. This Bark Processing and Disposal Safe Operating Procedure sets out a consistent, defensible method for managing bark from the moment it is produced through to its reuse, recycling or disposal, in line with Australian WHS and environmental expectations.

The procedure details how workers should collect, segregate, process, store, transport and dispose of bark while controlling hazards such as plant and vehicle interaction, manual handling, slips and trips, dust inhalation, noise and fire. It also addresses contamination risks (e.g. treated timber, rubbish, metal), stormwater protection and record-keeping for waste tracking. By implementing this SOP, businesses can demonstrate due diligence, protect workers and visitors, reduce the likelihood of fires and regulatory breaches, and improve operational efficiency by standardising bark handling across all sites and shifts.

Key Benefits

• Reduce the risk of fires and spontaneous combustion in bark piles through controlled stockpile design and monitoring.
• Ensure workers handle and process bark safely, minimising manual handling injuries, slips, trips and falls.
• Standardise bark collection, processing, storage and disposal practices across sites, shifts and contractors.
• Demonstrate compliance with WHS and environmental obligations by documenting clear responsibilities and controls.
• Optimise resource recovery opportunities by separating clean bark suitable for mulch or compost from contaminated waste.
