Researchers from the National Institute for Research and Development in the Danube Delta are testing 12 types of bricks made from reed and hemp. These materials are being developed under the ReBORN project, which aims to promote sustainable construction and energy efficiency. The bricks are designed to be fire-resistant and environmentally friendly, utilizing local resources. Community involvement has increased as locals see the benefits of these materials. The project, funded by the European Climate Initiative, will conclude in May 2027, with results expected early next year. Certification for large-scale production remains a challenge.
