Forests cover about a third of the planet and play a fundamental role for life on Earth. According to Peter Wohlleben, author of the book “The Secret Life of Trees”, through fungal weaves, specimens of a forest can communicate with each other, exchange nutrients, help out the weakest plants, and organize survival strategies, which is essential for the healthy growth of individuals. The preservation of existing forests and the creation of new ones are essential for biodiversity and natural recovery, but also to meet the demand for wood. According to a report by the WWF (World Wide Fund for Nature), it is estimated that the amount of wood harvested in the world will triple by the year 2050, with the increase in population and income in developing countries. In addition, it is estimated that there will be an increased use of wood to manufacture biofuels, pharmaceuticals, plastics, cosmetics, consumer electronics and textiles. Searching for wood substitutes can be a smart path towards a sustainable future, especially if the alternatives are made using waste generated by other industries. Pyrus, for example, is an oil-free wood material produced sustainably with bacterial cellulose waste repurposed from the kombucha industry.
