HDPE milk bottle research and development
05 Jan 2011
A WRAP project has identified some “quick wins” that together would enable the production of milk bottles with at least 30% recycled HDPE plastic (rHDPE) to be acceptable from a colour perspective. This has the potential to enable around 50% rHDPE to be achieved.

Milk Bottle R&D Final Report
(772 kb)
The amount of recycled HDPE plastic (rHDPE) that can be used to make new milk bottles is limited because the recycled material currently has a green hue to it. This research and development project has identified a number of solutions that would reduce the green hue and enable the production of milk bottles that are visually acceptable with at least 30% rHDPE content.
This supports the achievement of Milk Roadmap targets for higher recycled content in new milk bottles and helps achieve environmental benefits by reducing the use of virgin plastic. This uses resources more efficiently, reduces waste to landfill, saves energy and reduces greenhouse gas emissions.
