Sardinian cork finds new application as eco-detergent and shampoo

A unique-in-the-world solution based entirely on organic materials

The island of Sardinia has long been known as a region that has produced some fine cork – the bark of the oak tree used widely as a wine bottle stopper. Years of research, however, from local sustainable construction materials company Edizero Architecture for peace, have helped develop pioneering new detergent products based on that organic plant, which can change the way the world cleans up.

The fulcrum of innovation is the discovery of the extraordinary antimicrobial, antioxidant and depolluting qualities of cork transformed into an extract for cleaning. From bark to acorns, the plant has been studied for its properties. The project was considered revolutionary right from its debut, so much so that it received the Riccarda Serri award from Skineco, an international society of eco-dermatological medicine.

An example of localism in green innovation

The new line of products is called ‘Detergents of peace’ reflecting the company’s name. The ‘peace’ part here references that the origin of all the materials and substances used in the creation of the products are completely conflict-free.

Cork is considered one of Sardinia’s most characteristic natural resources and manufactured products. The town Calangianus is the island’s major cork production area. Hundreds of cork enterprises (sugherifici), large and small, are concentrated around this town of just four thousand inhabitants. The cork industry is divided into two main sectors, industrial and artisanal. 

The company thus has easy and convenient access to its main source and the years of research demonstrate intimate knowledge of its main source material.

These are the first detergents in the world based on cork and renewable agricultural, wood and marine surpluses that do not become waste but rather precious extracts with antibacterial, sanitizing and protective properties from pollutants.

"They are also the first in the world with the lowest weight and the highest yield: with 30 grams of water-soluble powder you get a litre of fresh liquid detergent rich in active ingredients with two months of duration in the different types of shampoos, shower gel, house cleaning, dishes, laundry, dog shampoo, street furniture, all specific to wash and sanitize without polluting," explains Daniela Ducato, from Edizero Architecture for peace, as quoted by ANSA news agency.
