Inert waste is neither chemically nor biologically reactive and will not decompose or cause pollution in the environment, such as soil, sand, stone, concrete, bricks, tiles and ceramics. It’s stable – meaning it doesn’t undergo significant physical, chemical or biological transformations – and doesn’t pose a threat to water, air or soil quality.
To find out if the muck-away from your construction or demolition site is inert, the material will need to be physically and chemically assessed. The testing process also needs to assess any potential leaching behaviour.
How does it differ from non-hazardous muck?
Although not hazardous, this type of muck encompasses a broad range of materials present in construction and demolition waste, including organic matter, soil and other non-inert substances that can decompose, undergo changes over time or contain low levels of contamination that can leach from the material.
Why should it be recycled?
Recycling inert waste is critical for several reasons.
- It reduces landfill use.
Inert waste takes up significant space in landfills – by recycling, we can reduce the burden on these sites. - It conserves resources.
Recycling the waste into aggregates saves natural resources, reducing the need for new raw materials. - It has economic benefits.
Inert waste can be recycled into aggregates for use in various industries, creating economic opportunities and saving costs on raw materials. - It’s better for the environment.
Minimising the amount of waste being sent to landfills helps protect ecosystems and reduces greenhouse gas emissions associated with waste decomposition.
What does the recycling process involve?
Producing aggregates from inert waste is subject to a stringent Quality Protocol. The recycling process involves several steps to ensure that the materials are effectively repurposed.
- Collection and transportation
Inert waste is collected from construction sites, demolition projects and other sources. It is then transported to a recycling facility. - Sorting and separation
At the recycling facility, the waste is sorted to remove any contaminants such as plastics, metals and organic materials. Advanced technologies like air classifiers, screens and magnets are used to ensure the purity of the inert materials. - Crushing and grinding
Once sorted, the material is crushed and ground into smaller pieces. For instance, concrete is broken down into aggregates of various sizes, which can be reused in construction projects. - Screening
The crushed materials are then screened to separate different sizes of aggregates. This step ensures that the recycled products meet the required specifications for their intended use. - Washing
In some instances, the inert waste is washed to remove fine particles and impurities. This is particularly important for recycled glass, which must be clean in order to be melted and reformed. - Reusing and repurposing
Recycled aggregates are commonly used in roadworks, foundations and as base materials for new buildings. Recycled glass can be used to manufacture new products, including tiles, and even as a component in asphalt.
