The ZAP project has released its first report, highlighting that more work needs to be done to reduce plastic packaging waste on construction sites – especially as the industry is the second highest plastic consumer by sector.
The report identifies a lack of initiatives to reduce packaging in the construction sector, alongside a limited number of publicly declared commitments. Some companies, the ZAP project notes, do have targets committing them to increasing recycled content.
A lack of substitute materials was also found, specifically for shrink wrap and straps.
Construction sites are difficult environments to segregate plastic packaging materials, the ZAP project says, with plastic packaging often ending up mixed in a general skip, leading to contamination and problems with processing at a waste transfer station.
Interviews conducted by the ZAP project also identified on-site barriers, as well as issues pertaining to the variety of plastic types present in packaging – making them difficult to recycle.
Following a packaging hierarchy could see the construction sector become more sustainable, says ZAP. The order is as follows: Elimination by removing packaging altogether (e.g. use of bulk deliveries); reduction (e.g. use of larger pack sizes), optimisation (e.g. light weighting); reuse (e.g. reusable crates); recycling (into new products); recovery (energy from waste); and disposal to landfill.
The ZAP project aims to develop ‘scalable solutions to help combat the prevalence of avoidable packaging plastic waste in construction.’ The project’s funded research will link with real-world construction projects to build case studies and develop guidance and training. This, the project says, will highlight positive actions that the whole supply chain and sector can do, potentially helping other organisations reach zero avoidable waste.
The next step for the initiative is to assess and evaluate a number of these opportunities across the construction lifecycle.

How will the government and DMOs address the challenges of including glass in DRS while ensuring a level playing field across the UK?
There's no easy solution to include glass in the DRS while maintaining a level playing field. Potential approaches include a phased introduction of glass, potentially with higher deposits to reflect its logistical challenges. The government and DMOs could incentivise innovation in glass packaging design and subsidise dedicated return points for glass-handling. Exemptions for smaller businesses unable to handle glass might also be necessary. Any successful solution will likely blend several approaches. It must address the differing priorities of devolved administrations, balance environmental benefits with logistical and cost implications, and be supported by robust consumer education campaigns emphasizing the importance of glass recycling.
