# Air-Filtering Architecture The 'CO2 Scraper' is a Carbon-Positive Creation for High-Pollution Area By Marissa Brassfield | Published 2009-02-09 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/co2-scraper References: [core77](http://www.core77.com/blog/object_culture/a_different_sort_of_skyscraper_one_that_cleans_the_environment_12584.asp) & [nectardesign](http://www.nectardesign.com/industrial-products/green-concept-design-co2-scraper) The 'CO2 Scraper' by Nectar Product Development is a [carbon-positive building](https://www.trendhunter.com/trends/populus-hotel) that will actually [purify the surrounding air](https://www.trendhunter.com/trends/airsancta) cleaner. It's meant for high-pollution areas like factories, but I could see several of these in global metropolitan areas noted for their pollution like Los Angeles and Beijing. The 'CO2 Scraper' is a giant skyscraper that is essentially a [vertical forest](https://www.trendhunter.com/trends/wonderwoods-vertical-forest). It can hold 200-400 large trees, which naturally absorb carbon dioxide and convert it into oxygen. A windmill-powered irrigation system fertilizes and waters the trees; the only outside electricity Nectar Product Development says the 'CO2 Scraper' needs is for an elevator so that maintenance workers can ascend the tower. ## Trend Insights (Trend Hunter) - Score: 2.9/10 - Popularity: 28% | Activity: 52% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What's Driving This Trend - **Air-purifying Architecture:** Designing buildings that actively purify the surrounding air using natural resources and innovative technology - **Vertical Forests:** Integrating nature into urban spaces by incorporating large trees onto skyscrapers and other tall structures - **Renewable Energy-powered Buildings:** Creating structures that utilize renewable energy sources to support their functionality and maintenance ### Who This Affects Most - **Architecture and Design:** The construction industry should explore innovative ways to develop structures that actively improve air quality in high-pollution areas - **Renewable Energy:** The renewable energy industry can collaborate with architecture firms to incorporate renewable energy systems into the design and functionality of air-purifying buildings - **Urban Planning:** The field of urban planning can embrace the concept of vertical forests as a means of creating sustainable, livable urban environments ## Related on Trend Hunter - [Air Purifying Architectural Towers](https://www.trendhunter.com/trends/verto-air-purification.md) - [Plant-Supporting Air Purifiers](https://www.trendhunter.com/trends/florapur-air-purifier-concept.md) - [Algae-Powered Air Purifiers](https://www.trendhunter.com/trends/algenair-aerium.md) - [Plant-Powered Air Purifiers](https://www.trendhunter.com/trends/neo-px-air-purifier.md) - [Plant-Powered Air Purifiers](https://www.trendhunter.com/trends/decorative-air-purifier.md) - [Barcon-Negative Architecture](https://www.trendhunter.com/trends/picoplanktonics.md) - [Air-Purifying Houseplants](https://www.trendhunter.com/trends/neoplants.md) - [Pollution-Removing Murals](https://www.trendhunter.com/trends/this-campaign-sucks.md) - [Rain-Collecting Skyscrapers](https://www.trendhunter.com/trends/bpas-architects.md)
