In 2017 China closed its doors to taking most plastic waste, this brought home the issue of what to do with it. Currently there are few resources in Aotearoa New Zealand repurposing this waste into new products. Of these, they are limited to a select few types of plastics.

Local councils are under immense pressure to find a solution to their growing stockpiles of unwanted mixed plastics without having to revert to landfilling this material.

Working with councils and development partners, Road Science has developed a solution to optimise standard asphalt mixes utilising the hard plastic waste and feeding it directly back into the local infrastructure where it came from.  David's PowerPoint Presentation
