Construction is an essential part of New Zealand's economy, but it also generates a significant amount of waste. Construction waste includes materials such as concrete, timber, metals, and plastics, which can have a significant impact on the environment if not managed properly. As a result, waste minimisation in construction has become a crucial aspect for a sustainable future in New Zealand.
The New Zealand construction industry is committed to reducing its environmental impact and promoting sustainable development. The Scaffolding, Access and Rigging New Zealand (SARNZ) and other organizations have been working towards this goal by implementing waste minimisation strategies and promoting sustainable practices. For example, using shrinkwrap to contain waste on construction sites has become a popular option for companies looking to reduce their environmental impact.
Shrinkwrap is a durable and flexible material that can be used to create a temporary enclosure for construction sites. It is commonly used to protect buildings from the elements during construction, but it can also be used to contain waste materials. By using shrinkwrap, companies can prevent waste materials from being blown away, littering the site or harming the environment. This can reduce the need for site cleanups, which can be costly and time-consuming.
Waste minimisation in construction can also be achieved through the reuse and recycling of materials. For example, timber and metal can be reused in future construction projects, and concrete can be crushed and used as aggregate. This not only reduces waste but also conserves resources and reduces the need for new materials. Companies can work with local recycling and resource recovery facilities to ensure that waste materials are properly sorted and recycled.
Waste minimisation in construction is not only important for the environment but also for the bottom line of businesses. By reducing waste and reusing materials, companies can save money on disposal and purchasing costs. They can also improve their reputation by demonstrating their commitment to sustainability and promoting their eco-friendly practices.
To support waste minimisation in construction, SARNZ alongside Environmental Solutions Research Centre – Auckland Unitec, have been collaborating to research, educate and create resources on sustainable practices. Collectively, it was identified that companies were unsure of what their options were, or if their waste was being recycled in a way that contributes to a circular economy. To give companies certainty and clarity, the below decision tree was created. This will be continuously updated to ensure industry has up to date information.
Waste minimisation in construction is a crucial aspect for a sustainable future in New Zealand. SARNZ are committed to continually working on improved options for our members. By working together, the construction industry can achieve its goal of reducing waste and promoting sustainable development in New Zealand.
