Here at Hinwil, the first commercial carbon-capture plant went online. The plant collects 900 tons of carbon a year, piping it into a nearby greenhouses to boost vegetable growth. The company Climeworks hopes to quickly scale up its technology and capture one percent of the global carbon dioxide produced by burning fossil fuels by 2025. the direct air capture technology uses a proprietary filter to absorb atmospheric CO2 as it passes through the plant, according to a press release. Once the filter is saturated, it is heated to 100 degrees Celsius, causing it to release the gas. The CO2 is then redirected to a greenhouse where it will help grow vegetables like tomatoes and cucumbers. The carbon boost could improve the lettuce harvest by up to 20 percent.
