Vodka
This carbon-negative vodka is the first alcohol of its kind. Every bottle of spirit captures 1.5 kilograms of CO2 from the atmosphere, which is as much as eight trees can absorb within their lifetime. This alcohol is produced with a process mimicking photosynthesis, using air, water and sun as an input and oxygen as the only by-product.
When fermenting fruits or grain into alcohol, CO2 is usually a by-product of this conversion. A New York based initiative called Air Company, developed an alcohol production method where CO2 is absorbed in the production process. CO2 is broken apart with water in a special conversion system that they developed. This CO2 based conversion system could make the fermentation process normally used to make alcohol redundant. The alcohol produced is chemically pure and can be used as a primary material for products like spirits, fragrances and sanitisers.
