Eco-friendly packaging made out of algae developed in Russia

22 may 2024

Sergey Marinin, a graduate student at the Faculty of Ecology of Chelyabinsk State University, presented a new type of bio-packaging called algocarton (algae cardboard).

This innovative material is made from planktonic algae with the necessary strength and flexibility. Algocarton may become a promising replacement for conventional plastic and cardboard, offering more environmentally friendly and biodegradable packaging.

Modern packaging materials such as cardboard and plastic pose a significant environmental threat due to their slow decomposition. Algocarton, on the contrary, is biodegradable, which significantly reduces its impact on ecosystems. Algae for algocarton production are widely used in various industries, which makes this material not only environmentally safe, but also economical.

The development of algocarton production technology can be key in the creation of new environmentally friendly packaging materials that will find application both in industry and in everyday life.

The development and implementation of algocarton may significantly reduce the use of traditional plastic and cardboard packages, diminishing the amount of waste and its negative impact on the environment, according to nia.eco.
