GREEN TIPS
Reduced frequent renovation/retrofitting works
From time to time, shopping malls undergo renovation so as to attract and retain shoppers. However,
renovation and retrofitting works would invariably lead to waste generation. The more frequent such works
are taken, the more waste is produced. Mall owners shall try to prevent waste in the first place and avoid
frequent renovation except when it is necessary.
The provision of leasing incentives is also recommended to attract long-term tenancy commitment from
tenants and to minimise the turnover rate of retail leases.
6.1.1 Recommendations for site practices
As waste generation by the construction industry has always been a problem of treatment and management, strategies
on waste reduction should be well planned. Some examples are presented here mainly for contractors’ reference.
Shopping mall developers, shop owners and tenants may also use such information for auditing purposes.
During demolition
Planning stage
• Conduct an on-site survey of the materials to be demolished/collected inside the existing premises
• Prepare a demolition
to identify key waste types and waste reduction targets
Demolition stage
• Conduct induction and toolbox training for workers
• Dismantle manually, prior to demolition using a hand-held breaker, bulldozer etc., to remove reusable furniture,
electrical appliances and salvageable materials such as metals, timber, bricks and tiles
• Adopt selective sequential demolition to remove one type of material at a time to avoid mixing
• Reuse excavated spoils as back-fill materials on-site and off-site
• Separate demolition waste by category
