interior fitting-out
Planning stage
• Select materials that can be reused in the event of alteration to minimise wastage or disposal (e.g. recycle wall blocks)
Construction stage
• Sort waste for reuse and recycling
• Avoid the accumulation of renovation waste by requiring its removal once it is
generated and, if possible, assign a dedicated area for its temporary storage
while awaiting removal
• Use covered wheeled bins and trolleys for temporary storage and transportation
