Portugal to put a new twist on cork industry—from footwear, fashion to furniture as global demand for wine wanes

Producers highlight the environmentally friendly properties of cork, which is lightweight, recyclable, waterproof and fire-resistant, to encourage its use in diverse settings.

Cork is obtained by stripping the bark of cork oak trees every nine years in a careful process that allows the tree to regenerate and grow, making the industry naturally sustainable.

The material has “a negative carbon footprint because it comes from a tree that captures CO2 day and night”, Antonio Rios de Amorim, the CEO of the world’s largest cork producer Corticeira Amorim, told AFP.

The push to diversify comes as global sales of wine decline, reducing demand for cork wine stoppers which have long faced competition from cheaper plastic stoppers and screw tops.

“Periods of slowdown must be used to question what we do,” said Amorim, whose ancestors founded Corticeira Amorim 154 years ago in the northern village of Mozelos, about 30 kilometres (18 miles) south of second city Porto.

Booster rockets, metro seats

Thanks to cork’s cell-like structure, the material is elastic and highly impermeable, making it suitable to make shoes as well as ties, pants and other clothes.

Furniture designers are also increasingly drawn to the material.

British designer Tom Dixon has called it a “dream material” and put out a range of dark cork furniture that includes tables, stools and shelves using cork from Portugal.

The Lisbon metro in 2020 replaced the fabric lining on all seats of its train fleet with cork, an easier to maintain material.

Builders have been drawn to the material because of its unique thermal insulation and sound absorption properties.

Cork is also finding its way into space. It is used in thermal protection coating on booster rockets because of its resistance “to strong variations in temperature”, said Amorim.

Making wine bottle stoppers, however, remains the main activity for Portugal’s cork industry, which employs around 8,000 people.

Corticeira Amorim makes some six billion cork wine bottle stoppers per year, almost all of them for export mainly to Chile, France and the United States.

It accounts for 70 percent of the global market share for cork stoppers and posted sales of 985 million euros (one billion dollars) in 2023, slightly lower than in the previous…
