Due to their low bulk density, transportation of mattresses from collection sites to recyclers is a significant contributor to the total cost of recycling. In a joint project with G&G Transport, a specialized trailer was developed that compresses mattresses by at least 50% of their original volume. In the California test trials, the project team demonstrated that mattresses could be safely and economically compressed without impacting recyclability. Commercial scale shipments using the first-generation trailer resulted in a 26% reduction in total transportation costs. A larger second-generation trailer, which is under development, has the potential to reduce total transportation costs by 45%.
