The 12-Week Breakdown Process of 100% Compostable Cement Bags—Will keep 250,000+ plastic bags out of landfills

“Bluey” COMPOSTABLE cement BAGS include a rain barrier designed to
absorb less moisture than conventional polyethylene film bags;
250,000+ plastic bags will no longer be added to landfills;
& have experienced milestones throughout the biodegradation process
including removal of unsafe toxins & elements! 

Following two years of research and development, in January 2020, Bluey—a Civil Engineering solutions, innovative products, and services—began overhauling the entire BluCem bagged product line, switching to Australia’s first 100% compostable cement bag. The switch to the compostable bags means that the annual 250,000+ plastic bags will no longer be added to landfill.

The Bluey compostable cement bags have undergone a Biodegradability Assessment, conducted at the Commonwealth Scientific and Industrial Research Organization (CSIRO). The testing has been successful and concurs with AS 4736 as well as EN 14332. The diagram to the right shows the progressive breakdown of the bags over a 12-week period.

The CSIRO identified in the Biodegradability Assessment that there were milestones throughout the biodegradation process which marked the removal of unsafe toxins and elements. These include:

  • Worm Toxicity Test: AS4736 (14 days)
  • Plant Toxicity (14 days)
  • Biodegradation (45 days)
  • Becomes residual compost (In 84 days).

The bags also include a rain barrier which is designed to absorb less moisture than conventional polyethylene film bags, meaning storage practices remain the same. The water-repellent surface is formulated to keep a high tensile strength even on wet construction sites, preventing rupture.

Other Benefits Include:

  • Improved shelf life
  • CSIRO & USFDA approved
  • Meets Australian Standards Requirements
  • Improved product filling speeds
  • Reduction in landfill
  • Positive customer and consumer feedback

Daniel Bosco, CEO-Bluey, said, “It is not about being ‘eco-friendly’, ‘green’, or otherwise making a bold political statement. It is just a very small step toward ensuring that when we are gone, nobody will know that we were here”.
