This is an issue which is becoming increasingly important for organic wine-growers, since a wine which tastes of cork will not satisfy the customers and will mean increasing costs for the wine dealers if they have to replace cork-tainted wines.
Apart from its origin, cork, which is a natural product, is no longer environmentally friendly if you consider how it is produced using fertilizers and fungicides on the oak trees and how the bark is turned into a finished cork for a bottle of wine. The production of "natural corks" and pressed corks, which are made from waste products of natural cork, involves processes such as boiling, bleaching, coloring and sizing, which are not exactly beneficial to the environment.
In addition, these products also cause problems for getting rid of household waste, which is no longer brought to a garbage dump but is now burned, and the burning of these requires a great deal of energy. On the other hand plastic corks, made of polyethylene, produce more energy when they are burned than is required to ignite them.
Environmentally conscious wine-growers use unbleached and uncolored natural corks for their high-quality organic wines, and plastic corks are also no longer taboo.
Environmentally conscious wine drinkers do not put their natural corks into the household waste; they have them recycled as insulation material. If there is no collection point where you live, you can send us the natural corks you have accumulated.
