Recycled Cardboard by A4Adesign

Honeycombed-board is made of recycled paper and water-based glue, and can itself be recycled. During the production phase, all unused pieces are collected and reintroduced into the manufacturing process. The honeycomb is one of the most compression-resistant structures in nature, and can support up to 400000 N/mq pressure. That is why such extraordinarily light materials can resist such strenuous conditions.
