Construction projects in Sydney and the rest of Australia generate large amounts of waste. This inevitably raises the question, where does construction waste actually go? What’s more, the rubbish and leftover materials from these projects are varied, and many require specialised disposal services.
At Sydney City Rubbish, we’re experts in removing construction waste and disposing of it in a safe and sustainable manner. Our team is passionate about providing efficient and reliable services for building and demolition projects of all shapes and sizes. In this article, we’ll take a look at where construction waste actually goes, and what happens to it.

What is construction waste?
Construction waste, also known as builders waste or building rubbish, consists of materials generated during construction, renovation, and demolition projects. It includes everything from wood and metal to plastics and plasterboard. Proper disposal and recycling of construction rubbish are crucial for reducing landfill waste and promoting sustainability in the industry.
How much waste does the construction industry produce?
The construction industry is one of the largest contributors to waste worldwide. In Australia, construction and demolition activities generate millions of tonnes of waste each year. The good news is that a significant portion of this waste can be recycled or repurposed, reducing the amount of construction junk that ends up in landfills.
Where do the different materials go?
Each type of building waste follows a different disposal path. While some materials are easily recyclable, others require specialised handling. Here’s a breakdown of where the various components of construction waste go:
Timber and wood products
Timber waste, including offcuts and pallets, is often repurposed for landscaping, mulch, or biofuel. Untreated wood can be recycled, whereas treated or painted timber may require disposal in specialised facilities. Many recycling centres accept clean timber, which can be chipped and turned into new materials. However, wood that has been chemically treated or coated may pose environmental risks and needs to be carefully handled.
Scrap metals
Metals such as steel, aluminium, and copper are highly recyclable. Scrap metal from builders waste is usually collected by recycling centres, where it is melted down and reused in new construction or manufacturing projects. This process significantly reduces the need for virgin metal extraction, conserving natural resources. Even smaller metal scraps, such as nails and wiring, can be processed and repurposed, making metal one of the most sustainable construction materials.
Concrete and brick
Crushed concrete and bricks are commonly reused as road base or aggregate in new building projects. Recycling concrete helps reduce demand for new raw materials and minimises landfill waste. Many demolition sites now have on-site crushing equipment to repurpose these materials efficiently. Additionally, repurposed bricks can be used in landscaping projects or as part of reclaimed building materials for sustainable construction.
Plaster products
Plasterboard and drywall can sometimes be recycled to create new gypsum-based products. However, contaminated or damp plasterboard may need to be disposed of in landfills. When properly processed, gypsum from plasterboard can be used in soil conditioning or as an additive in new construction materials. Recycling facilities that accept plasterboard often require it to be free from adhesives, nails, and paint for successful processing.
Tiles
Unused or salvaged tiles can be donated or reused in smaller projects. Broken tiles are often crushed and repurposed as aggregate or fill material. Some specialised facilities recycle ceramic and porcelain tiles into new products, reducing waste in the construction industry. Additionally, intact tiles can be repurposed for artistic projects, mosaics, or resale in salvage yards for future use.
Glass
Glass from windows and doors is usually recycled into new glass products or used in insulation manufacturing. Contaminated or laminated glass, however, may require special handling. Recycling glass reduces energy consumption compared to producing new glass from raw materials. Specialised facilities process glass by removing contaminants and sorting it by type before melting it down for reuse in bottles, fibreglass, or architectural applications.
Plastics
Construction plastics, including PVC pipes and plastic sheeting, can often be recycled. However, mixed plastics or contaminated materials may be harder to process. Many types of plastic waste can be shredded and melted into new construction materials, such as plastic lumber or insulation. The challenge lies in sorting different plastic types correctly, as not all recycling facilities accept mixed plastic waste due to varying melting points and chemical compositions.
Carpet and other flooring materials
Carpet, vinyl, and laminate flooring can sometimes be recycled, depending on their material composition. Many flooring materials are repurposed into new products or used as industrial fuel. Some carpet manufacturers offer take-back programs to recycle old carpets into new ones. Additionally, reclaimed flooring materials can be refurbished and resold, reducing waste and promoting circular economy practices in the building industry.

FAQs about construction waste
How do you deal with large volumes of rubbish from a building project?
Handling large volumes of building rubbish requires an efficient waste management plan. This typically involves on-site waste separation, skip bins for recyclables, and partnerships with licensed waste removal services.
Should the builder take away the rubbish?
In many cases, builders are responsible for disposing of builders waste. However, waste removal is not always included in construction contracts, so it’s essential to confirm this with your builder or hire a professional waste removal service.
