Information on how to reduce and manage waste on construction sites
The construction industry
The UK construction industry is responsible for producing over 36 million tonnes of landfill waste every year. This equates to approximately 35% of total waste generated. So it's essential to reduce and manage waste on construction sites.
Fortunately the situation is changing in the UK. There are a growing number of sustainable waste management solutions that can be used.
Sources of waste
Waste varies according to the phase of construction, method and the type of building.
A wide range of waste materials are produced throughout the construction project.
Most waste is produced on site through:
- over ordering
- damage by mishandling
- unsuitable/lack of storage
- weather damage
But unnecessary packaging of construction materials also produces an excessive amount of waste such as plastic and cardboard.
Secure storage of lightweight waste is essential to avoid it being blown across the site and neighbouring areas.
Managing and monitoring the different types of waste on a construction site requires a detailed waste minimisation strategy. This requires careful consideration throughout the design, construction and occupancy phases.
There are three basic strategies for dealing with waste:
Waste prevention is the ideal. This can be addressed first by identifying possible waste streams early on in the construction process, and then designing for their minimisation.
Using standard sizes for building components (for example, windows, doors) can prevent future waste.
Over ordering often generates waste. It's estimated that 13 million tonnes of new building materials are thrown away every year. Time spent ensuring exact calculations of materials are made can help to reduce the level of waste. Just-in-time deliveries can also help to reduce waste created by poor storage and weather damage.
Once waste has been produced, the best method of managing it is through reuse either on the existing site, or a nearby site. Consider storing reusable waste separately as some materials could be reclaimed or even sold.
Sustainable building practice goes one step further than conventional practice. It helps reduce residential waste through designing for waste minimisation in the operation of the building. For example:
- greywater recycling
- composting toilets
- on site food composting
- off-site recycling facilities
Waste as a valuable resource
Effective waste management can:
- reduce building and operating costs
- enhance the reputation of the building industry
- generate new revenue streams through developing recycling and reclaiming markets
Reducing construction waste also:
- saves landfill space
- conserves valuable natural resources
- saves energy
- creates less pollution by reducing transportation and manufacturing processes, with a mitigating effect on climate change
The UK Government has introduced a landfill tax, aggregate levy and other waste management regulations. These encourage the diversion of waste from landfill, promote reuse and recycle strategies, and emphasise environmental responsibility.
But further measures are needed if the construction industry is to realise waste minimisation as part of its core activity. And if we really want to address our waste problems, the biggest change that needs to occur is a shift in people's thinking.
We need to see waste as not just a problem of disposal, but as a valuable resource to be treated and used with respect and care.
Disposal of business or commercial waste
Norfolk is part of the #SCRAPflytipping campaign, which aims to educate businesses regarding their responsibilities around waste disposal. Controlling waste at source and only passing it on to registered and legitimate waste disposal companies is the key to preventing illegal waste disposal.
- keep waste to a minimum by doing everything you reasonably can to prevent, reuse, recycle or recover waste (in that order) - get help to do this on the Wrap website
- sort and store waste safely and securely
- complete a waste transfer note for each load of waste that leaves your premises
- check if your waste carrier is registered to dispose of waste
- not allow the waste carrier to dispose of your waste illegally (and report them to Crimestoppers if they do)
You have extra responsibilities if you’re dealing with hazardous waste.
The Considerate Constructors Scheme is a not-for-profit, independent organisation founded in 1997 by the construction industry to improve its image.
Construction sites, companies and suppliers voluntarily register with the Scheme and agree to abide by the Code of Considerate Practice. It's designed to encourage best practice beyond statutory requirements.
For more information on the Code, please visit the Code of Constructors Scheme website.
