Timber 

Overview: Due to its flexibility, durability, and appealing visual attraction, timber has multiple applications in the construction industry. The amount of timber waste generated from C&D activities is influenced by the life span of the building materials. Australia generated 2.4 Mt of timber waste in 2016-17. The share of the C&D sector as the second-largest timber waste generator was almost 612 kt (25.8%), behind C&I with almost 1,524kt (64.3 %). Among the jurisdictions, NSW, Vic and Qld had the largest amount of timber waste in total and in the C&D waste stream in 2016-2017. In Australia, timber waste is classified into three major categories: untreated timber (Type A), engineered timber products (Type B), and treated timber (Type C). This classification determines the management strategy for timber waste.

Supply chain (circular economy): We developed a model to identified the opportunities for reducing timber waste disposal throughout the lifecycle of timber products. The opportunities are conceptualised in the timber-LoWMoR model.

 

 

 

 

 

 

 

 

 

 

   

  Timber LoWMoR  model  

The peak industry group, the Timber Development Association (TDA), has established the National Timber Product Stewardship Group (here), an industry/government steering group set up to identify and facilitate product stewardship initiatives in the industry. In 2007, TDA released a product stewardship strategy, “Timber-More Life”, which set a national target to double the recovery rate of wood waste by 2017. In 2007, the recovery rate was estimated to be 32%.

 Recommendations to reduce timber waste disposal

  • To use non disposable metal formwork instead of timber one in several construction projects

  • To redefine and harmonise timber waste in national and jurisdictional regulations and policies

  • To exclude timber waste recovered from construction activities from generic timber waste

  • To improve the existing and employing new varieties of machinery instead of old and obsolete one help reducing the wood waste

  • To fund the development of waste energy recovery infrastructure particularly those that are able to recover energy from chemically treated timber waste

  • To consider precast timber frames in the designs
